| ABSTRACT |
| Older
individuals, as a group, tend to experience difficulty sleeping compared
to younger adults. Improving sleep in the elderly would have beneficial
public health consequences. This study utilized 8 sedentary, older
adults, 78.1 ± 3.1 years of age, who participated in a six-month long
resistance training (RT) program. The Pittsburgh Sleep Quality Index
(PSQI) was used to examine sleep quality, and a 1 repetition max test
(1-RM) was used to determine upper (bench press) and lower (leg press)
body strength. Total strength, defined as the sum of the bench press
and leg press 1-RM results, was also reported. The training resulted
in significant improvements (p < 0.05) in total (19%) and upper
body (52%) strength and in sleep quality (38%). Future studies should
examine the effects of strength gain/loss and time-of-day training
on sleep quality.
