Serious adverse events were rare , and no serious events were reported to be directly related to the exercise programme .
This review provides evidence that PRT is an effective intervention for improving physical functioning in  older people , including improving strength and the performance of some simple and complex activities .
BACKGROUND Muscle weakness in old age is associated with physical function decline .
Progressive resistance strength training ( PRT ) exercises are design ed to increase strength .
OBJECTIVES To assess the effects of PRT on older people and identify adverse events .
Effect of ceasing creatine supplementation while maintaining resistance training in older men.
The authors previously found that creatine ( Cr ) combined with 12 weeks of resistance training enhanced muscle strength and endurance and lean tissue mass ( LTM ) in older men . Their purpose in this study was to assess these variables with cessation of Cr combined with 12 weeks of reduced training ( 33 % lower volume ) in a subgroup of these men ( n = 8 , 73 years old ) compared with 5 men ( 69 years old ) who did not receive Cr .  Strength ( 1-repetition maximum [ 1-RM ] ) , endurance ( maximum number of repetitions over 3 sets at 70 - 80 % 1-RM ) , and LTM ( dual-energy X-ray absorptiometry ) were assessed before and after 12 weeks of Cr cessation combined with reduced-volume training . No changes in strength or LTM occurred . Muscle endurance was significantly reduced ( 7 - 21 % ; p < .05 ) , with the rate of change similar between groups . Withdrawal from Cr had no effect on the rate of strength , endurance , and loss of lean tissue mass with 12 weeks of reduced-volume training
