Effects of Habitual Exercise on Risk Factors of Chronic Non-Communicable Diseases and Thermoregulatory Ability in Middle Aged
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.18 Vol.18】
A study was conducted to investigate the effects of habitual exercise on risk factors of chronic non-communicable diseases and thermoregulatory ability in middle aded. Two different approaches were adopted for this purpose.
(1) The subjects were divided into two groups; a habitual exercise group of 75 women [mean age (SD); 49.1 (7.7) years], and a control group of 301 women [age 49.5 (8.4) years]. The former included subjects who regularly took walking exercise or enjoyed sports activities, and the latter those who did not undertake any physical exercise on a regular basis.
The serum total cholesterol (TC) and triglyceride (TG) levels were found to be significantly lower in the habitual exercise group than in the control group. Grip strength and standing trunk flexion were significantly higher in the habitual exercise group than in the control group. Body temperature was lower and the body weight loss rate was higher in the habitual exercises than in the control group during walking exercise in a hot environment.
(2) Twenty-seven women [age 53.4 (8.2) years] followed a walking program for 20～60 min more than 3 times a week for three months at an intensity level of 50%HRmax.
Following this walking, the distribution of body fat decreased significantly, but the serum TC, TG and HDL-cholesterol did not change significantly after three months. Grip strength, standing trunk flexion and jumping reaction time were increased significantly by walking exercise.
In conclusion, these results suggest that long-term low-intensity exercise can improve both the serum lipid profile and physical fitness.
