The Effects of Exercise on Perceived Stress and IL-6 Levels Among Older Adults
Purpose of review This review highlights recent work evaluating the relationship between exercise , physical activity and physical and mental health . Both cross-sectional and longitudinal studies , as well as r and omized clinical trials , are included . Special attention is given to physical conditions , including obesity , cancer , cardiovascular disease and sexual dysfunction . Furthermore , studies relating physical activity to depression and other mood states are review ed . The studies include diverse ethnic population s , including men and women , as well as several age groups ( e.g. adolescents , middle-aged and older adults ) . Recent findings Results of the studies continue to support a growing literature suggesting that exercise , physical activity and physical-activity interventions have beneficial effects across several physical and mental-health outcomes . Generally , participants engaging in regular physical activity display more desirable health outcomes across a variety of physical conditions . Similarly , participants in r and omized clinical trials of physical-activity interventions show better health outcomes , including better general and health-related quality of life , better functional capacity and better mood states . Summary The studies have several implication s for clinical practice and research . Most work suggests that exercise and physical activity are associated with better quality of life and health outcomes . Therefore , assessment and promotion of exercise and physical activity may be beneficial in achieving desired benefits across several population s. Several limitations were noted , particularly in research involving r and omized clinical trials . These trials tend to involve limited sample sizes with short follow-up periods , thus limiting the clinical implication s of the benefits associated with physical activity .

OBJECTIVES To systematic ally evaluate evidence from published Cochrane Review s of clinical trials to summarise the evidence regarding the effectiveness and safety of rehabilitation interventions for people with MS ( pwMS ) , to improve patient outcomes , and to highlight current gaps in knowledge . METHODS We search ed the Cochrane Data base of Systematic Review s up to December 2017 , to identify Cochrane Review s that assessed the effectiveness of organised rehabilitation interventions for pwMS . Two review ers independently assessed the quality of included review s , using the Revised Assessment of Multiple Systematic Review s ( R-AMSTAR ) tool , and the quality of the evidence for reported outcomes , using the GRADE framework . MAIN RESULTS Overall , we included 15 review s published in the Cochrane Library , comprising 164 r and omised controlled trials ( RCTs ) and four controlled clinical trials , with a total of 10,396 participants . The included review s evaluated a wide range of rehabilitation interventions , including : physical activity and exercise therapy , hyperbaric oxygen therapy ( HBOT ) , whole-body vibration , occupational therapy , cognitive and psychological interventions , nutritional and dietary supplements , vocational rehabilitation , information provision , telerehabilitation , and interventions for the management of spasticity . We assessed all review s to be of high to moderate method ological quality , based on R-AMSTAR criteria .Moderate- quality evidence suggested that physical therapeutic modalities ( exercise and physical activities ) improved functional outcomes ( mobility , muscular strength ) , reduced impairment ( fatigue ) , and improved participation ( quality of life ) . Moderate- quality evidence suggested that inpatient or outpatient multidisciplinary rehabilitation programmes led to longer-term gains at the levels of activity and participation , and interventions that provided information improved patient knowledge . Low-qualitty evidence suggested that neuropsychological interventions , symptom-management programmes ( spasticity ) , whole body vibration , and telerehabilitation improved some patient outcomes . Evidence for other rehabilitation modalities was inconclusive , due to lack of robust studies . AUTHORS ' CONCLUSIONS The evidence suggests that regular specialist evaluation and follow-up to assess the needs of patients with all types of MS for appropriate rehabilitation interventions may be of benefit , although the certainty of evidence varies across the different types of interventions evaluated by the review s. Structured , multidisciplinary rehabilitation programmes and physical therapy ( exercise or physical activities ) can improve functional outcomes ( mobility , muscle strength , aerobic capacity ) , and quality of life . Overall , the evidence for many rehabilitation interventions should be interpreted cautiously , as the majority of included review s did not include data from current studies . More studies , with appropriate design , which report the type and intensity of modalities and their cost-effectiveness are needed to address the current gaps in knowledge BACKGROUND Although many Japanese older adults spend more than an hour each day walking for exercise , the intensity is often lower than the minimum level associated with various health benefits . The purpose of this study was to evaluate the efficacy of a lifestyle physical activity intervention on improving quantity and quality of daily physical activity ( DPA ) as well as cardiorespiratory endurance in community-dwelling older women . METHODS 68 women ( 60 - 78 yr of age ) were r and omly assigned to either a lifestyle physical activity intervention group ( LIFE ) or control group . During the 12-wk intervention , feedback based on accelerometer DPA data ( number of daily steps ( STEPS ) and time spent performing daily moderate intensity physical activity ( MPA ) was provided to each participant in LIFE every two weeks . Cardiorespiratory endurance was evaluated using the 12-Minute Walk Test ( 12-MW ) . RESULTS Following the 12-wk intervention , significant group interactions were observed for STEPS , MPA , and cardiorespiratory endurance . LIFE increased STEPS by 16 % , MPA by 53 % , and the distance walked during the 12-MW by 10 % . CONCLUSIONS Promotion of DPA using accelerometers can significantly improve quantity and quality of daily physical activity as well as cardiorespiratory endurance in older women Introduction The health benefits of regular cardiovascular exercise are well-known . Such exercise , however , has traditionally been defined as vigorous physical activity , such as jogging , swimming , or aerobic dance . Exercise of moderate intensity also promotes health , and many U.S. adults may be experiencing the health benefits of exercise through lifestyle activities of moderate intensity , such as yard work , housework , or walking for transportation . Until recently , public health surveillance systems have not included assessment s of this type of physical activity , focusing on exercise of vigorous intensity . We used an enhanced surveillance tool to describe the prevalence and amount of both moderate-intensity and vigorous-intensity physical activity among U.S. adults . Methods We analyzed data from the 2001 Behavioral Risk Factor Surveillance System , a state-based , r and om-digit  – dialed telephone survey administered to U.S. adults aged 18 years and older ( n = 82,834 men and 120,286 women ) .  Physical activity behavior was assessed using questions design ed to quantify the frequency of participation in moderate- or vigorous-intensity physical activities performed during leisure time or for household chores and transportation . Results Overall , 45 % of adults ( 48 % of men and 43 % of women ) were active at recommended levels during nonworking hours ( at least 30 minutes five or more days per week in moderate-intensity activities , equivalent to brisk walking , or at least 20 minutes three or more days per week in vigorous activities , equivalent to running , heavy yard work , or aerobic dance ) . Less than 16 % of adults ( 15 % of men and 17 % of women ) reported no moderate or vigorous activity in a usual week . Conclusion Integrating surveillance of lifestyle activities into national systems is possible , and doing so may provide a more accurate representation of the prevalence of recommended levels of physical activity . These results , however , suggest that the majority of U.S. adults are not active at levels associated with the promotion and maintenance of health Increasing evidence suggests that physical activity can prevent some aspects of mental illness in older people such as depression , dementia and Alzheimer ’s disease . Additionally , limited research has shown that engagement in structured exercise can improve aspects of psychological well-being such as mood and self-perceptions in older adults . However , the relationship between incidental daily activity such as walking or time spent sedentary , with psychological well-being has not been investigated . The Better Ageing Project provided an opportunity to assess well-being and quality of life using st and ardised question naires with 176 adults aged 70 and over .  Accelerometry was used to objective ly assess daily energy expended in physical activity at different levels of intensity . In addition , an assessment of the impact of the 12-month Better Ageing structured group exercise programme was assessed through question naires and interviews . Total daily physical activity energy expenditure ( joules/day ) and amount of time spent in activity of at least moderate intensity were weakly related ( r = 0.20–0.28 ) to quality of life , subjective well-being and physical self-perceptions . Time spent sedentary ( min/day ) was weakly and negatively related to several mental health indicators . The quantitative data showed only minor psychological benefits of the exercise intervention . In contrast , interviews with 27 research participants and 4 exercise leaders suggested that important improvements in perceived function and social benefits had been experienced PURPOSE Declines in physical functioning ( PF ) among elderly cancer patients threaten quality of life and the ability to maintain independence . Adherence to healthy lifestyle behaviors may prevent functional decline . PATIENTS AND METHODS Project Leading the Way in Exercise and Diet ( LEAD ) , an intervention development study of the Pepper Older Americans Independence Center , aim ed to determine whether breast and prostate cancer survivors ( age 65 + years ) assigned to a 6-month home-based diet and exercise intervention  experienced improvements in PF when compared with an attention control arm receiving general health information . An accrual target was set at 420 , and PF ( Short Form-36 subscale ) , physical activity ( Community Healthy Activities Models Program for Seniors ) , and diet quality ( index from 3-day recalls ) were assessed at baseline and at 6 and 12 months ( 6 months after intervention ) . RESULTS This developmental project did not achieve its accrual target ( N = 182 ) ; however , PF change scores were in the direction and of the magnitude projected . Baseline to 6-month change scores in the intervention versus the control arms were as follows : PF , + 3.1 v -0.5 ( P = .23 ) ; physical activity energy expenditure , + 111 kcal/wk v -400 kcal/wk ( P = .13 ) ; and diet quality index , + 2.2 v -2.9 ( P = .003 ) , respectively . Differences between arms diminished during the postintervention period . CONCLUSION These findings suggest that home-based diet and exercise interventions hold promise in improving lifestyle behaviors among older cancer survivors , changes that trend toward improved PF . Future studies should incorporate larger sample sizes and interventions that sustain long-term effects and also take into account secular trends ; these efforts will require adequate planning and re sources to overcome the numerous barriers to intervening in this difficult to reach yet vulnerable population OBJECTIVE health-related quality of life ( HRQOL ) and mental well-being are associated with healthy ageing . Physical activity positively impacts both HRQOL and mental well-being .  Yoga is a physical activity that can be modified to suits the needs of older people and is growing in popularity . We conducted a systematic review with meta- analysis to determine the impact of yoga-based exercise on  HRQOL and mental well-being in people aged 60 + . METHODS search es were conducted for relevant trials in the following electronic data bases ; MEDLINE , EMBASE , Cochrane Central Register of Controlled Trials , CINAHL , Allied and Complementary Medicine Data base , PsycINFO and the Physiotherapy Evidence Data base ( PEDro ) from inception to January 2017 . Trials that evaluated the effect of physical yoga on HRQOL and /or on mental well-being  in people aged 60 + years were included . Data on HRQOL and mental well-being were extracted . St and ardised mean differences and 95 % confidence intervals ( CI ) were calculated using r and om effects models . Method ological quality of trials was assessed using the PEDro scale . RESULTS twelve trials of high method ological quality ( mean PEDro score 6.1 ) , totalling 752 participants , were identified and provided data for the meta- analysis . Yoga produced a medium effect on HRQOL ( Hedges ' g = 0.51 , 95 % CI 0.25 - 0.76 , 12 trials ) and a small effect on mental well-being ( Hedges ' g = 0.38 , 95 % CI 0.15 - 0.62 , 12 trials ) . CONCLUSION yoga interventions result ed in small to moderate improvements in both HRQOL and mental well-being in people aged 60 + years . Further , research is needed to determine the optimal dose of yoga to maximise health impact . PROSPERO REGISTRATION NUMBER ( CRD42016052458 ) Osteoarthritis ( OA ) of the knee leads to restrictions of physical activity and ability to perform activities of daily living . Obesity is a risk factor for knee OA and it appears to exacerbate knee pain and disability . The Arthritis , Diet , and Activity Promotion Trial ( ADAPT ) was developed to test the efficacy of lifestyle behavioral changes on physical function , pain , and disability in obese , sedentary older adults with knee OA . This controlled trial r and omized 316 sedentary overweight and obese older adults in a two-by-two factorial design into one of four 18-month duration intervention groups : Healthy Lifestyle Control ; Dietary Weight Loss ; Structured Exercise ; or Combined Exercise and Dietary Weight Loss . The weight-loss goal for the diet groups was a 5 % loss at 18 months . The intervention was modeled from principles derived from the group dynamics literature and social cognitive theory . Exercise training consisted of aerobic and strength training for 60 minutes , three times per week in a group and home-based setting . The primary outcome measure was self-report of physical function using the Western Ontario and McMaster University Osteoarthritis Index . Other measurements included timed stair climb , distance walked in 6 minutes , strength , gait , knee pain , health-related quality of life , knee radiographs , body weight , dietary intake , and cost-effectiveness of the interventions . We report baseline data stratified by level of overweight and obesity focusing on self-reported physical function and physical performance tasks . The results from ADAPT will provide approaches clinicians should recommend for behavioral therapies that effectively reduce the incidence of disability associated with knee OA BACKGROUND A r and omized controlled trial was conducted to examine : ( a ) the effect of two physical activity modes on changes in subjective well-being ( SWB ) over the course of a 12-month period in older , formerly sedentary adults ( N = 174 , M age = 65.5 years ) and ( b ) the role played by physical activity participation and social support in changes in SWB over time . METHOD Participants were r and omized into either an aerobic activity group or a stretching and toning group . Structural equation modeling was employed to conduct multiple sample latent growth curve analyses of individual growth in measures of SWB ( happiness , satisfaction with life , and loneliness ) over time . RESULTS A curvilinear growth pattern was revealed with well-being significantly improving over the course of the intervention followed by significant declines at the 6-month follow-up . Subsequent structural analyses were conducted showing that frequency of exercise participation was a significant predictor of improvement in satisfaction with life , whereas social relations were related to increases in satisfaction with life and reductions in loneliness . Improvements in social relations and exercise frequency also helped to buffer the declines in satisfaction with life at follow-up . CONCLUSIONS It appears that social relations integral to the exercise environment are significant determinants of subjective well-being in older adults . Findings are discussed in terms of how physical activity environments might be structured to maximize improvements in more global well-being constructs such as satisfaction with life BACKGROUND Despite well-known benefits of physical activity for older adults , about two thirds are underactive . Community-based programs are needed to facilitate increased physical activity . We examine the effectiveness of CHAMPS II , an inclusive , choice-based physical activity promotion program to increase lifetime physical activity levels of seniors . CHAMPS guided participants to choose activities that took into account their health , preferences , and abilities . It offered information on ways for them to exercise safely , motivate themselves , overcome barriers , and develop a balanced exercise regimen . METHODS A 1-year r and omized controlled trial was conducted with physically underactive seniors in a multispecialty group practice . Changes in self-reported physical activity by group were evaluated using ANCOVA , controlling for age and sex . RESULTS Of 173 r and omized subjects , 164 ( 95 % ) completed the trial . Subjects were aged 65 to 90 years ( M = 74 , SD = 6 ) ; 66 % were female . The intervention group increased estimated caloric expenditure by 487 calories/week in moderate ( or greater ) intensity activities ( MET > /= 3.0 ; p < .001 ) and by 687 calories/week in physical activities of any intensity ( p < .001 ) . Control group changes were negligible . Between-group analyses found that the changes were significantly different in both measures ( p values < .05 ) . Overweight persons especially benefited from this program . The program was as effective for women , older adults ( 75 + ) , and those who did not set aside time to exercise at baseline . CONCLUSIONS The program led to meaningful physical activity increases . Individually tailored programs to encourage lifestyle changes in seniors may be effective and applicable to health care and community setting BACKGROUND Project ACTIVE was a r and omized clinical trial comparing two physical activity interventions , lifestyle and traditional structured exercise . The two interventions were evaluated and compared in terms of cost effectiveness and ability to enhance physical activity among sedentary adults . DESIGN This was a r and omized clinical trial . SETTING / PARTICIPANTS The study included 235 sedentary but healthy community-dwelling adults . INTERVENTION A center-based lifestyle intervention that consisted of behavioral skills training was compared to a structured exercise intervention that included supervised , center-based exercise . MAIN OUTCOME MEASURES The main outcome measures of interest included cost , cardiorespiratory fitness , and physical activity . RESULTS Both interventions were effective in increasing physical activity and fitness . At 6 months , the costs of the lifestyle and structured interventions were , respectively , $ 46.53 and $ 190.24 per participant per month . At 24 months these costs were $ 17.15 and $ 49.31 per participant per month . At both 6 months and 24 months , the lifestyle intervention was more cost-effective than the structured intervention for most outcomes measures . CONCLUSIONS A behaviorally-based lifestyle intervention approach in which participants are taught behavioral skills to increase their physical activity by integrating moderate-intensity physical activity into their daily lives is more cost-effective than a structured exercise program in improving physical activity and cardiorespiratory health . This study represents one of the first attempts to compare the efficiency of intervention alternatives for improving physical activity among healthy , sedentary adults Background The purpose was to conduct systematic review s of the relationship between physical activity of healthy community-dwelling older ( > 65 years ) adults and outcomes of  functional limitations , disability , or loss of independence .  Methods Prospect i ve cohort studies with an outcome related to functional independence or to cognitive function  were search ed , as well as exercise training interventions that reported a functional outcome . Electronic data base search strategies were used to identify citations which were screened ( title and abstract ) for inclusion . Included articles were review ed to complete st and ardized data extraction tables , and assess study quality . An established system of assessing the level and grade of evidence for recommendations was employed . Results Sixty-six studies met inclusion criteria for the relationship between physical activity and functional independence , and 34 were included with a cognitive function outcome . Greater physical activity of an aerobic nature ( categorized by a variety of methods ) was associated with higher functional status ( expressed by a host of outcome measures ) in older age . For functional independence , moderate ( and high ) levels of physical activity appeared effective in conferring a reduced risk ( odds ratio ~0.5 ) of functional limitations or disability . Limitation in higher level performance outcomes was reduced ( odds ratio ~0.5 ) with vigorous ( or high ) activity with an apparent dose-response of moderate through to high activity . Exercise training interventions ( including aerobic and resistance ) of older adults showed improvement in physiological and functional measures , and suggestion of longer-term reduction in incidence of mobility disability . A relatively high level of physical activity was related to better cognitive function and reduced risk of developing dementia ; however , there were mixed results of the effects of exercise interventions on cognitive function indices . Conclusions There is a consistency of findings across studies and a range of outcome measures related to functional independence ; regular aerobic activity and short-term exercise programmes confer a reduced risk of functional limitations and disability in older age . Although a precise characterization of a minimal or effective physical activity dose to maintain functional independence is difficult , it appears moderate to higher levels of activity are effective and there may be a threshold of at least moderate activity for significant outcomes Objectives : To determine the effects of gymnastics on the health related quality of life ( HRQoL ) and functional status of independently living people , aged 65 to 80 years .  Gymnastics formed part of the More Exercise for Seniors ( MBvO in Dutch ) programme , a group based exercise programme for older adults in the Netherl and s. It has been widely implemented since 1980 . Design : R and omised controlled trial with pretest and post-test measurements . Intervention : The exercise programme given by experienced instructors lasted 10 weeks and was given weekly ( MBvO1 ; n = 125 , six groups ) or twice weekly ( MBvO2 ; n = 68 , six groups ) . The control group ( n = 193 ) was offered a health education programme . Setting : Community dwelling of older people , with a comparatively low level of fitness as assessed with the Groningen Fitness test for the Elderly . Results : No significant effects were found on the HRQoL ( Vitality Plus Scale , TAAQoL , and R AND -36 ) and the functional status ( Physical Performance Test and the Groningen Activity Restriction Scale ) . The MBvO2 group , with a low level of physical activity at baseline , showed the only improvement found on the Vitality Plus Scale ( F = 4.53 ; p = 0.01 ) . Conclusions : MBvO gymnastics once a week did not provide benefits in HRQoL and functional status after 10 weeks . However , participants with a low level of physical activity may benefit from MBvO gymnastics if they participate twice a week . To improve the health of the general public , sedentary older adults should be recruited and encouraged to combine MBvO with the health enhancing physical activity guidelines BACKGROUND Given the evidence that regular physical activity produces substantial health benefits , participation in sports , exercise , and recreation is widely encouraged . The objective of this study was to describe participation in sports , exercise , and recreational physical activities among US adults . METHODS Data from 2 national surveys of respondents age 18 years and older were analyzed . Respondents to the American Time Use Survey ( ATUS ) from 2003 through 2005 ( N=45,246 ) reported all activities on 1 r and omly selected survey day . Respondents to the National Health and Nutrition Examination Survey ( NHANES ) from 1999 through 2004 ( N=17,061 ) reported leisure-time physical activities in the 30 days before the interview . RESULTS One-quarter of adults participated in any  sport , exercise , or recreational activity  on a r and om day , and 60.9 % of adults participated in any leisure-time activity in the previous 30 days . The most common types of activities were walking , gardening and yard work , and other forms of exercise . The sports and recreational activities had typical duration s of 1/2 to 3 hours per session , and the exercise activities typically lasted 1 hour or less . CONCLUSIONS The prevalence of sports , exercise , and recreational physical activities is generally low among US adults ; exercise is the most commonly reported type of activity OBJECTIVES To compare the effect of high-intensity aerobic interval exercise ( HIA ) with home-based exercise ( HB ) in older adults with chronic disease soon after discharge from the hospital . DESIGN R and omized controlled trial . SETTING Hospital . PARTICIPANTS Community-dwelling older adults aged 70 to 92 ( N = 115 ) were recruited while in the hospital . After discharge , they were r and omized to HIA group ( n = 59 ) or HB ( n = 56 ) . INTERVENTION High-intensity aerobic interval exercise ( HIA ) consisted of endurance , strength , and balance exercises . The HB consisted of low-intensity exercises and telephone follow-up from a physical therapist . MEASUREMENTS Health-related quality of life ( HRQOL ) was assessed using the Medical Outcomes Study 36-item Short Form Survey , physical fitness was measured using the Senior Fitness Test , and physical activity was assessed using the Physical Activity Scale for the Elderly . RESULTS Intention-to-treat analysis showed that both groups improved their HRQOL and physical activity after 3 months . Improvements on the Senior Fitness Test ( chair st and , arm curl and 6-minute walk ( 6MWT ) ) were significantly greater in the HIA group than the HB group . The mean difference was 25.9 m on the 6MWT ( P = .001 , effect size d = 0.2 ) , 1.3 per 30 seconds on the chair st and s mean ( P = .001 , effect size d = 0.3 ) , and 1.6 per 30 seconds on the arm curl ( P = .001 , effect size d = 0.4 ) . CONCLUSION High-intensity aerobic interval exercise ( HIA ) participants significantly improved their physical fitness . Both groups increased their HRQOL and physical activity . The findings suggest that exercise therapy should be incorporated as a part of the treatment for older people at risk for functional decline PURPOSE To examine the effect of resistance exercises on self-reported physical function and activities of daily living ( ADL ) in older adults with osteoporosis or osteopenia . METHODS A search of available literature was conducted using PubMed , CINAHL , SPORTD iscus , PEDro , ProQuest Nursing and Allied Health Source , and Cochrane Controlled Trials Register . Studies were included if they involved ( 1 ) r and omized controlled trials ; ( 2 ) participants with osteoporosis or osteopenia ; ( 3 ) resistance exercise as an intervention ;  and ( 4 ) self-report of physical function or ADL . Articles were independently review ed for quality by two authors using the Physiotherapy Evidence Data base ( PEDro ) scale . Cohen 's d effect size was calculated by dividing st and ardized mean differences by the st and ard deviation to determine treatment effect in terms of physical function or ADL . RESULTS Five full-text articles were selected for inclusion . PEDro scores ranged from 5 to 7 ( out of 10 ) . Effect size mean differences as a result of resistance intervention ranged from 0.08 to 1.74 , suggesting " trivial " to " large " effects on self-reported physical function and ADL . CONCLUSION RESULTS suggest that interventions using resistance training have a beneficial impact on the domains of physical function and ADL in participants with osteoporosis or osteopenia . More high- quality studies are needed to lend further validity to this supposition BACKGROUND Regular physical activity has been shown to have many health benefits . However , many older people are physically inactive . OBJECTIVE To investigate why older people are reluctant to participate in leisure time physical activity and to identify strategies to encourage increased activity . DESIGN Cross-sectional survey . SETTING 16 general practice s in Dundee , Scotl and . METHODS 409 r and omly selected older people ( 65 - 84 years ) who lived independently were interviewed at home . Forty-six percent of those invited to take part were recruited into the study . RESULTS Levels of knowledge about the specific health benefits of physical activity were high . Almost all participants ( 95 % ) believed that physical activity was beneficial and 79 % believed that they did enough to keep healthy . However , 36 % did no leisure time physical activity and a further 17 % did less than 2 hours per week . Regression modelling identified 11 factors that exerted significant independent effects on levels of leisure time physical activity .  The most powerful deterrent was lack of interest ( OR = 7.8 ) . Other factors included lack of daily access to a car , shortness of breath , joint pain , dislike of going out alone or in the evening , perceived lack of fitness , lack of energy , doubting that exercise can lengthen life , not belonging to a group and doubting that meeting new people is beneficial . CONCLUSIONS Increasing leisure time physical activities poses major challenges . Beliefs about desirable levels of activity in older people would need to be changed . Action would be needed to relieve physical symptoms and address fears about perceived ability to undertake physical activity . Finally , easily accessible facilities would be needed to encourage participation in physical activity Biochemical markers of inflammation have been used in recent physical activity intervention studies . However , these same biochemical markers , mainly proinflammatory cytokines , may also be influenced by the individual ’s level of stress and mood . Accordingly , this pilot study was implemented to determine the effect of a physical activity intervention on perceived stress , mood , quality of life , serum interleukin-6 ( IL-6 ) , and cortisol among 10 older adults , age 60 to 90 . The results were compared to those of 10 older adults who were not engaging in regular physical activity . The 10-week intervention was applied using  student nurses who taught the older adults how to calculate 60 % of their maximum heart rate while ambulating for 30-min intervals . After the 10-week period , the participants in the exercise group reported significant improvements in stress , mood , and several quality of life indices . They also demonstrated a significant decrease in serum IL-6 . Stress , mood , and quality of life scores in the exercise group were also significantly improved compared to the control group . This study adds information on the specific intensity , duration , and frequency of exercise necessary to achieve improvements in psychological variables and IL-6 levels . It also supports the need to measure psychological stress in physical activity intervention studies . Although the psychological variables were highly correlated , there were only weak correlations found with IL-6 , suggesting that other factors are likely involved in reducing IL-6 when engaging in low-impact physical activity
Due to lack of high quality studies and often only one manuscript reporting on a particular determinant , we concluded " insufficient evidence " for most associations between determinants and physical activity or exercise .
Background The health benefits of regular physical activity and exercise have been widely acknowledged .
Unfortunately , a decline in physical activity is observed in older adults .
Knowledge of the determinants of physical activity ( unstructured activity incorporated in daily life ) and exercise ( structured , planned and repetitive activities ) is needed to effectively promote an active lifestyle .
Our aim was to systematic ally review determinants of physical activity and exercise participation among healthy older adults , considering the method ological quality of the included studies .
