This study was designed to examine the psychological benefits of anaerobic exercise for older adults. Specifically, strength training was employed to examine the effects on mood and anxiety in a group of healthy but sedentary older women. 36 women (mean age = 68.5 yr.) were randomly assigned to groups given high intensity or moderate intensity strength training or to a control group. Strength training was conducted three days a week for 12 weeks. After the training period, both high and moderate strength-training programs produced marked improvements in muscle strength and body composition compared to the control subjects. The average improvements in the high and moderate intensity strength-training groups for muscle strength were 40.5 and 35.5%, respectively, and for percent body fat 1.52 and 2.50%, respectively. As for psychological changes, both training groups significantly improved positive mood (vigor), and the moderate intensity group significantly reduced trait anxiety compared to means of the control group. Also, both training groups showed some decrease in tension and state anxiety after the training period. These findings provide evidence for the effectiveness of anaerobic training to enhance perception of psychological well-being in older women. A moderate intensity rather than high intensity of training regimen may be more beneficial for sedentary older women to improve psychological health.
In the 1980s, tax policy changes mitigated the redistributive effect of income tax. The present study attempts to explore how different the redistributive effect of the income tax reforms in Japan is among age groups, using Japanese household microdata for the period 1984–2009. The following results are obtained. First, the overall redistributive effect was greatest for the elderly group, followed by the middle‐aged group, and then the young group. Furthermore, this trend increased steadily over time. Second, the difference in total redistributive effects between the young and elderly increased owing to a large reduction in the base effect for the young.
