Effects of concurrent training with vascular occlusion on muscle hypertrophy in elderly


The American College of Sports Medicine recommends resistance and endurance training for improvement and maintenance of health in elderly. However, when both training modes are combined (concurrent training - CT), there are less gains of skeletal muscle mass, mainly in type II muscle fiber hypertrophy due to the effect of interference. The reduction of type II muscle fiber leads to the decrease in the ability to produce strength rapidly (i.e. power muscle and rates of force development), which increases the difficulties in performing daily activities (e. g. climb stairs, get up from the chair, etc.) and the risk of falling at this age group. Reducing the volume of CT may be a strategy to avoid the interference effect, however, it is still not clear whether the best way is to reduce the amount of resistance training (RT), endurance training (ET) or both. The decrease in total RT (series x repetitions x load) can be interesting, since it would reduce the risk of injury, as well as cardiovascular overload in the elderly. However, high intensities of resistance training are recommended (> 65% 1-RM) for muscle hypertrophy which provides a high total volume. On the other hand, past decade studies have shown that low intensity RT (20-50% 1-RM), when combined with moderate vascular occlusion (RTO) in the exercised muscle groups, promotes hypertrophy and muscle strength gains similar to high intensity RT. Thus, RTO associated with ET (concurrent training with vascular occlusion - CTO) can be another way of providing hypertrophy of type fibers with lower mechanical stress to the elderly, and also avoid the effect observed when the ET is associated with the high total volume RT.
