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 .
Comparison of heart-rate and blood-pressure increases during isokinetic eccentric versus isometric exercise in older adults.
The authors compared heart-rate and blood-pressure responses to typical isometric ( ISO ) and isokinetic ( 90 degrees /s ) eccentric ( ECC ) resistance-training protocol s in older adults . Twenty healthy older adults ( 74 + /- 5 years old ) performed r and omly ordered ISO and isokinetic ECC exercise ( 3 sets of 10 repetitions ) at a target intensity of 100 % of their peak ISO torque value . Heart rate and systolic ( SBP ) and diastolic ( DBP ) blood pressures were recorded continuously , and mean arterial pressure ( MAP ) and rate-pressure product ( RPP ) were calculated . ECC peak torque ( 139 + /- 33 N. m ) was significantly greater than ISO peak torque ( 115 + /- 26 N. m ; p < .001 ) . All variables increased significantly ( p < .001 ) during both ISO and ECC exercise .  Changes in SBP , DBP , MAP , and RPP were significantly greater during ISO exercise than during ECC exercise ( p < .001 ) . Clinical ly , an isokinetic ECC exercise program enables older adults to work at the same torque output with less cardiovascular stress than ISO exercise
