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 .
Functional-task exercise versus resistance strength exercise to improve daily function in older women: a randomized, controlled trial.
OBJECTIVES To determine whether a functional-task exercise program and a resistance exercise program have different effects on the ability of community-living older people to perform daily tasks . DESIGN A r and omized , controlled , single-blind trial . SETTING Community leisure center in Utrecht , the Netherl and s. PARTICIPANTS Ninety-eight healthy women aged 70 and older were r and omly assigned to the functional-task exercise program ( function group , n=33 ) , a resistance exercise program ( resistance group , n=34 ) , or a control group ( n=31 ) . Participants attended exercise classes three times a week for 12 weeks . MEASUREMENTS Functional task performance ( Assessment of Daily Activity Performance ( ADAP ) ) , isometric knee extensor strength ( IKES ) , h and grip strength , isometric elbow flexor strength ( IEFS ) , and leg extension power were measured at baseline , at the end of training ( at 3 months ) , and 6 months after the end of training ( at 9 months ) . RESULTS The ADAP total score of the function group ( mean change 6.8 , 95 % confidence interval (CI)=5.2 - 8.4 ) increased significantly more than that of the resistance group ( 3.2 , 95 % CI=1.3 - 5.0 ; P=.007 ) or the control group ( 0.3 , 95 % CI=-1.3 - 1.9 ; P<.001 ) . Moreover , the ADAP total score of the resistance group did not change significantly compared with that of the control group . In contrast , IKES and IEFS increased significantly in the resistance group ( 12.5 % , 95 % CI=3.8 - 21.3 and 8.6 % , 95 % CI=3.1 - 14.1 , respectively ) compared with the function group ( -2.1 % , 95 % CI=-5.4 - 1.3 ; P=.003 and 0.3 % , 95 % CI=-3.6 - 4.2 ; P=.03 , respectively ) and the control group ( -2.7 % , 95 % CI=-8.6 - 3.2 , P=.003 and 0.6 % , 95 % CI=-3.4 - 4.6 ; P=.04 , respectively ) . Six months after the end of training , the increase in ADAP scores was sustained in the function group ( P=.002 ) . CONCLUSION Functional-task exercises are more effective than resistance exercises at improving functional task performance in healthy elderly women and may have an important role in helping them maintain an independent lifestyle
