The multi-component exercise intervention composed by strength , endurance and balance training seems to be the best strategy to improve rate of falls , gait ability , balance , and strength performance in physically frail older adults
The aim of this review was to recommend training strategies that improve the functional capacity in physically frail older adults based on scientific literature , focusing specially in supervised exercise programs that improved muscle strength , fall risk , balance , and gait ability .
Dehydroepiandrosterone combined with exercise improves muscle strength and physical function in frail older women.
OBJECTIVES To investigate the effects of dehydroepi and rosterone ( DHEA ) combined with exercise on bone mass , strength , and physical function in older , frail women . DESIGN Double-blind , r and omized , placebo-controlled trial . SETTING A major medical institution . PARTICIPANTS Ninety-nine women ( mean age 76.6 ± 6.0 ) with low sulfated DHEA ( DHEAS ) levels , low bone mass , and frailty . INTERVENTION Participants received 50 mg/d DHEA or placebo for 6 months ; all received calcium and cholecalciferol . Women participated in 90-minute twice-weekly exercise regimens .  MEASUREMENTS Hormone levels , bone mineral density ( BMD ) , bone turnover markers , body composition , upper and lower extremity strength , physical performance . RESULTS Eighty-seven women ( 88 % ) completed 6 months . There were no significant changes in BMD or bone turnover markers  . DHEA supplementation result ed in gains in lower extremity strength ( from 459 ± 121 N to 484 ± 147 N ; P=.01 ) . There was also improvement in Short Physical Performance Battery score , a composite score that focuses on lower extremity function , in those taking DHEA ( from 10.1 ± 1.8 to 10.7 ± 1.9 ; P=.02 ) . There were significant changes in all hormone levels , including DHEAS , estradiol , estrone , and testosterone , and a decline in sex hormone-binding globulin levels in those taking DHEA . CONCLUSION DHEA supplementation improved lower extremity strength and function in older , frail women involved in a gentle exercise program of chair aerobics or yoga . No changes were found in BMD either due to small sample size , short duration of study or no effect . The physical function findings are promising and require further evaluation as frail women are at high risk for falls and fracture
