Fitness in special populations
TL;DR: In this paper, normal human responses to exercise and training are discussed, including personality, Behaviour, and Social Adjustment, as well as effective program design, and current fitness status.

Year-Long Physical Activity and Metabolic Syndrome in Older Japanese Adults: Cross-Sectional Data From the Nakanojo Study
Sungjin Park,Hyuntae Park,Fumiharu Togo,Eiji Watanabe,Akitomo Yasunaga,Kazuhiro Yoshiuchi,Roy J. Shephard,Yukitoshi Aoyagi +7 more
TL;DR: The metabolic syndrome is less likely in elderly people taking > 8000-10,000 steps/d, and reaching an intensity > 3 METs for > 20-30 min/d; relative to their sedentary peers.
Journal ArticleDOI
“Passive” exposure of asthmatic subjects to cigarette smoke
TL;DR: The data do not suggest that asthmatic subjects have an unusual sensitivity to cigarette smoke, and the only significant difference from the remaining astHmatic individuals was agreater FEV1.0 relative to the corresponding time in the control exposure.
Journal ArticleDOI
Effects of physical training on cardiovascular function following myocardial infarction
TL;DR: Findings were attributed to extracardiac factors, including a redistribution of blood flow, biochemical changes in the trained muscle, and a secondary reduction of sympathetic drive, including an increase of intrinsic myocardial contractility that develops if high-intensity training is sustained.
Journal ArticleDOI
Yearlong physical activity and regional stiffness of arteries in older adults: the Nakanojo Study
Yukitoshi Aoyagi,Hyuntae Park,Tetsuji Kakiyama,Sungjin Park,Kazuhiro Yoshiuchi,Roy J. Shephard +5 more
TL;DR: The hypothesis that the habitual physical activity of elderly individuals is associated with less arterial stiffening is tested, and characteristics of any dose/response relationship are explored, to determine those segments of the arterial tree where associations are most apparent.
