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 .
Homocysteine and lipoprotein levels following resistance training in older adults.
This investigation examined the effect of 6 months of high- or low-intensity resistance exercise on  serum homocysteine and lipoprotein ( a ) levels in adults aged 60 - 80 years . Forty-three men and women completed the study protocol . Subjects were r and omly assigned to a control ( n=10 ) , low-intensity ( LEX , n=18 ) , or high-intensity ( HEX , n=15 ) group . Subjects performed 6 months of resistance training at either 50 % of their one-repetition maximum for 13 repetitions ( LEX ) or 80 % of one-repetition maximum for eight repetitions ( HEX ) 3 times per week for 24 weeks . The load was increased by 5 % when their rating of perceived exertion dropped below 18 . One-repetition maximum ; serum homocysteine ; lipoprotein ( a ) ; total and high-density lipoprotein cholesterol ; and dietary intake of vitamins B12 , B6 , and folic acid were measured pre- and post study . Upper and lower body strength significantly ( p<0.05 ) increased for the LEX and HEX groups . Serum homocysteine decreased 5.30 % and 5.34 % for the LEX and HEX groups , respectively ( p<0.05 ) , but increased 6.1 % for the control group . A significant increase in lipoprotein ( a ) levels was noted in the control and LEX groups from pre- to post study . No significant differences were noted either pre- or post study for total and high-density lipoprotein cholesterol or any dietary variables . These data indicate that significant reductions in serum levels of homocysteine in the elderly can be derived from resistance exercise training
