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 .
Strength training can improve steadiness in persons with essential tremor.
We evaluated the effect of a strength-training program on the ability of persons with essential tremor  to exert steady forces with the index finger . Thirteen subjects with a diagnosis of essential tremor were assigned to three different groups : one group trained with heavy loads , one with light loads , and one did not perform any training . Subjects attempted to generate steady contractions during both postural and constant-force tasks . Steadiness was quantified by the root mean square amplitude of acceleration during postural tasks and the st and ard deviation and coefficient of variation of force during the constant-force tasks . Subjects who performed the training program with heavy loads experienced an increase in steadiness around the target force during the constant-force tasks . Subjects in the other two groups did not exhibit any changes . These findings suggest that strength training can decrease the magnitude of tremor . However , we did not observe any associated improvements in functional abilities
