DISEASES, SARCOPENIA
Measuring maximum isometric handgrip strength is common in the field of gerontology as it is considered as an important vitality surrogate for general fitness, cognitive status, frailty and sarcopenia in older adults [The effect of general exercise training and physical activity on handgrip strength is merely small to moderate. A meta-analysis of our group revealed that handgrip strength does not notably reflect adaptations from whole-body resistance training in healthy older adults [Physical activities, even when not directly affecting handgrip strength, with low intensity, can lead to important health benefits and risk reductions of both non-communicable diseases and aging-associated diseases [The results from the previous meta-analysis of our working group [Thus, the present RCT aims at analysing the effects of a multicomponent agility training approach on handgrip strength in healthy older adults. Furthermore, it aims analysing the correlation between the measurements of handgrip strength and agility operationalized by the agility challenge for the elderly (ACE). The hypothesis is that the multicomponent agility training improves maximum force and rate of force development of handgrip strength in healthy older adults. In addition, it is hypothesised that a higher value of maximum force and rate of force development correlates with a faster time measured for completing ACE.
