Twenty-three older women (61.6 ± 6.7 years; 74.2 ± 12.6 kg; 156.2 ± 5.9 cm) were randomized to a group that performed the exercises from multi- to single-joint order (MJ-SJ, n = 10) or a group that performed the exercises from single- to multi-joint order (SJ-MJ, n = 13). Both performed the same RT program (7 exercises, 3 sets of 10-15 maximum repetitions, twice a week, 16 weeks). Following the RT program, participants detrained for 16 weeks....
