Abstract:
In this study we examined the effects of 12 weeks of multicomponent training and 10 weeks detraining, on maximal strength (RM) and muscle power of the lower limbs. 22 volunteer elderly subjects (at an average of 68.5 ± 5.1 years old), participating in aquatic training, were divided in two groups GE (n=14) and GC (n=8). GE was submitted to an additional weekly session of progressive strength training, at 50- 85% of 1RM and 2 sets of 6-18 reps. Muscle fitness was assessed by applying maximum strength tests (1RM) and muscle power tests at 20%, 40% and 60% of1RM. Tests were carried out before training (M1), post training (M2) and after detraining (M3). Results: Following the training and the detraining periods, GE showed an increase in muscle strength (M1: 86.23 ± 34.69 kg; M2: 109.95 ± 38.29 kg; M3: 102.09 ± 30.15 kg; P ≤0.03) and in average propulsive power at 20% (M1: 75.65 ± 31.89 W; M2: 116.90 ± 57.94 W; M3: 107.10 ± 40.89 W; P ≤0.001) and at 60% (M1: 187.45 ± 65.68 W; M2: 260.97 ± 109.44 W; M3: 241.38 ± 86.97W; P ≤0.03). No significant differences were found for maximum strength or muscle power in GC. This study indicates that multicomponent training can be recommended for the elderly since it produces positive effects after training and it maintains greater muscular and functional fitness after prolonged periods of detraining.
