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 .
Resistive training and chromium picolinate: effects on inositols and liver and kidney functions in older adults.
This study assessed the effects of resistive training ( RT ) with or without chromium picolinate ( Cr-pic ) supplementation on the 24-h urinary excretions of myo-inositol , D-chiro-inositol , and pinitol , as well as clinical indices of kidney and liver functions . Thirty-two nondiabetic subjects , age 62 + /- 4 y , performed RT twice weekly for 12 wk and consumed either 924 ug Cr/d as Cr-pic ( n = 17 ) or a placebo ( n = 15 ) . Whole-body strength increased in all subjects by 20 % and urinary chromium excretion increased 47-fold in the Cr-pic group . Urinary myo-inositol , D-chiro-inositol , and pinitol were not changed with RT or influenced by Cr-pic .  Serum indices of kidney and liver functions were within clinical ly normal ranges at baseline and the end of the study . These results suggest that RT did not influence the urinary excretions of inositols . High dose Cr-pic did not influence the urinary excretion of inositols and the selected indices of kidney and liver functions in conjunction with RT
