身體活動量變化對中年男子身體適能及代謝症候群危險因子之影響

Abstract

背景：雖然規律且適度的運動有益身心健康，但仍有不少國人缺少運動習慣，以致增加罹患代謝症候群的風險。目的：探討身體活動量變化對中年男子身體適能與代謝症候群危險因子之影響。方法：以北部某家健康檢查醫院124位年齡約在40 ~ 64歲之健檢者為研究對象，根據兩次檢測時之身體活動量變化狀況分成兩組：體能活動量增加組 (increase group, IG)與體能活動量沒增加組 (no increase group, NIG)，每組各62位。所有受試者於兩次檢查中皆接受身體適能檢測及代謝症候群危險因子之分析。所得資料以混合設計二因子變異數分析檢驗身體活動量變化介入的效果。結果：(1)在第一次檢測時，IG組的身體活動量明顯低於NIG組；而第二次檢測時，IG組的身體活動量則明顯高於NIG組。(2)身體活動量變化對身體適能沒有造成明顯的改變，但所有受試者在第二次檢測時的體脂率及體脂重明顯較第一次檢測時來的低。(3)不同組MS盛行率沒有明顯的不同，但所有受試者第二次檢測時的MS盛行率明顯較第一次檢測時來的低。(4) 身體活動量變化對MS危險因子沒有造成明顯的改變，但所有受試者在第二次檢測時的TG及HDL較第一次檢測時有明顯的正向改變。結論：雖然身體活動量的變化無法明顯對中年男子身體適能及MS危險因子造成明顯的正向改變，但規律從事輕度身體活動即能有效減少MS盛行率，因此，為了維護身體健康，中年男子仍應規律從事適度的運動。Purpose: to investigate the effects of changes in physical activity on physical fitness and metabolic syndrome (MS) risk factors in middle-aged men. Methods: 124 (aged about 40 to 64 years of age) dealt with health check in the northern part of a health examination hospital for the study. According to the change of physical activity, participants were assigned into physical activity increase group (IG, n=62) and physical activity no increase group (NIG, n=10). Physical activity and MS risk factors were measured. Data were analyzed by a mixed design two-way ANOVA. Results: (1) Physical activity amount of IG was significantly lower than NIG (p< .05) at first test, while physical activity amount of IG was significantly higher than NIG (p< .05) at second test. (2) Changes in physical activity on the physical fitness without causing significant changes (p> .05), but the percentage of body fat and the mass of body fat test were significantly higher at the second than at the first test of all subjects (p< .05). (3) MS prevalence of different groups did not differ significantly (p> .05), but the prevalence of MS were significantly lower atthe second test than at the first test for all subjects (p< .05). (4) Changes in physical activity for MS risk factors caused no significant change (p> .05), but TG and HDL were significantly lower at the second test than at the first test of all subjects (p< .05). Conclusions: Although the changes in physical activity can’t cause significant positive change on physical fitness and MS risk factors in middle-aged men, but the lower physical activity life style can effectively reduce the prevalence of MS. Therefore, in order to maintain well health, middle-aged men should remain engaged in moderate exercise.
