Abstract
Background: Some studies indicated that training in sedentary persons is very important for decrease of aging changes. Many investigations have reported the increase in muscular strength as a consequence of training performed on the contralateral limb. There are few clinical trials that quantify the effect of cross training in sedentary adults.
Aim: The aim of the study was to evaluate of unilateral triceps brachialis resistance training on contralateral peak force in sedentary persons.
Methods: A total of 12 sedentary men (age = 68.18) with no history of resistance training and upper limb movement impairments enrolled in this study. Subjects performed unilateral elbow extension exercises in dominant upper limb, using progressive resistance training three times a week for eight weeks. After determining the maximal isometric force of elbow extension, the subjects performed 3 sets of 12 repetitions of the 6070% maximal force. The isometric force of elbow extension was measured at the start and after 2 weeks by tensiometer. Paired t test was used to analysis the data.
Results: The results showed that progressive unilateral elbow extension training led to an increase in maximal isometric force of triceps brachialis muscles at two sides (P<0.05).
Conclusion: During the period of immobility in one organ, by performing resistance exercises on the opposite side, it is possible to reduce the effects of immobility, preserve muscle strength, and shorten the healing and rehabilitation period, which is the result of the treatment and rehabilitation process. The increased muscle strength observed during training indicates positive effect of training in old adult. The increased muscle strength in untrained limb suggests the capacity of neuromuscular adaptation in old adult that it can be used in cases of limb immobility.
