muscle hypertrophy
HYPOXIC, CONTRACTION
In the present study, the effects of BFR training on enhancing the strength of often-overlooked lower extremity muscles in canoeing as well as the level of their contribution to ergometer performance were investigated. Whether gains would be achieved through LR exercises over a short period has a positive impact on the performance of canoe athletes was also investigated. The results of the study revealed that BFR training increased muscle thickness and strength in elite male canoe athletes compared to controls. The ergometer performance times significantly reduced as measured by sport-specific tests. Although no difference was observed in the development of the H muscles in the US CSA measurements between the groups, there was an increase in the RF muscle. The isokinetic measurement results did not show any significant differences among the right QF 60˚/s, left H 60˚/s, and left H 300˚/s PT in both groups. However, there was improvement in the left QF 60˚/s, right QF 300˚/s, and right and left H 300˚/s PT in both groups.Canoeing is a sport that requires strength and endurance in the upper and lower extremities as well as core strength and stability, especially due to the athlete precarious posture in a narrow boat.RT is commonly used to promote athletic development and it helps athletes meet the demands of their sport branches.In recent years, US has gained popularity for the measurement of skeletal muscle thickness and CSA.Yasuda et al measured the effects of a hypoxic and acidic environment on muscles using electromyography. This environment can inhibit both current muscle contraction and the potential for muscle contraction, which is relevant to BFR training. As suggested in the literature, occlusion-induced hypoxic and acidic environments can promote permanent muscle hypertrophy by forming additional fast-contracting motor units.In the present study, the force generated by canoe athletes was evaluated using an isokinetic dynamometer. The results showed that the increase in PT values in the BFR group was higher than that in CONT-gr. The higher force increase in INT-gr may be due to the hypoxic environment created by BFR, as noted in a previous study by Yasuda et al.BFR exercises offer a viable alternative in cases where resistance exercises are not recommended. Progressive RT, which involves adjusting the external load, sets, and repetitions, is known to promote strength and muscle size development.
