Effect of intense strength training on standing balance, walking speed, and sit-to-stand performance in older adults

Muscle size and strength decrease with aging, and the resultant muscle weakness has been implicated in increased risk of falls in older adults. These falls have large economic and functional costs. The purpose of this randomized, controlled study was to determine if an 8-week, 3-day per week intense...

Description
Summary:Muscle size and strength decrease with aging, and the resultant muscle weakness has been implicated in increased risk of falls in older adults. These falls have large economic and functional costs. The purpose of this randomized, controlled study was to determine if an 8-week, 3-day per week intense (77.8 +/- 3.4% of 1-repetition maximum [1RM]) strength training program could improve functional ability related to the risk of falling in subjects aged 61--87 years (mean 72, SD 6.3). Twelve strength-training-naive subjects performed two sets of 10 repetitions for six lower body exercises while 12 subjects served as nonintervention controls. Subjects were tested pre-, mid-, and postintervention for strength gain and on three tests of functional ability. Postintervention strength was significantly better (p
