采用问卷调查法对职业中专学生的体育锻炼和人际交往困扰及其关系进行研究。结果表明,职业中专尚有很大一部分学生在人际总分及其各维度上存在一定困扰或是严重困扰,女生在待人接物和异性交往方面好于男生,高年级学生在待人接物、异性交往和人际总分上好于低年级学生;大锻炼量学生的人际交往困扰少于中小锻炼量学生,而起主要作用的是每次参与锻炼的时间。  相似文献

《The aging male》2013,16(4):265-274
Background.?The present study sought to examine the association between physical exercise as a lifestyle habit with anthropometric parameters and body composition and aging in men.

Methods.?Intensity of exercise was scored as metabolic equivalent-min/week (MET-min/week) from data of the questionnaire, while anthropometric parameters and body composition were carried out by standard measuring instruments and dual-energy X-ray absorptiometry scanner, respectively.

Results.?Age was associated with decreases in bodyweight, height, total lean mass and bone mass, but an increase in fat mass. The negative association of lean mass with age was predominantly due to the negative association of lean masses in the legs and arm, while the positive association of fat mass with age was primarily due to the positive association of fat masses in the trunk and abdomen. Exercise of intensity greater than 1000 MET-min/week was significantly associated with higher lean and bone masses and lower fat mass. The increase in lean mass was predominantly in the legs, while the decreases in fat mass were in the trunk and abdomen.

Conclusion.?The study showed that the high intensity of physical exercise, equivalent to greater than 1000 MET-min/week, is required to effect beneficial changes in the body composition. Hence, results from the study support the importance of promoting a lifestyle habit of exercise of sufficient intensity in order to mitigate the increase risks of sarcopenia and obesity and their attendant ill effects on health in men as they age.  相似文献

Although physical activity can have substantial mental and physical health benefits, people with cerebral palsy usually lead sedentary lives. To understand, at an individual level, this inactivity, we interviewed a 29-year-old minimally active woman with cerebral palsy (Alana) about the meanings and experiences of physical activity throughout her life. Using a case-study approach, we found that Alana had adverse childhood experiences with physical activity, including: having to perform difficult, and sometimes painful, physiotherapy; wearing callipers to assist her walking; demonstrating limited competence at physical activity; being excluded from physical education and other organised physical activity at school; and feeling socially isolated from her classmates. These experiences seemed to contribute to feelings of difference/inferiority and the subsequent avoidance of physical activity, which, in turn, might have contributed to premature functional decline. Physical activity levels in people with cerebral palsy might be increased through focusing on enhancing childhood experiences.  相似文献

Abstract

The etiology, epidemiology, clinical presentation, diagnosis, and treatment of nonspecific urethritis (N.S.U.) is discussed. Chlamydia seems to be responsible for approximately 40–50% of cases while the etiology of the remainder remains obscrue. There seems to be reasonably good evidence for venereal transmission as well as for treatment of the female partner whether symptomatic or asymptomatic.

Tetracyline given for 21 days or oxytetracycline given for four days seem to be the most effective first line treatment regimens at this time.

Complications which include prostatitis, epididymitis, urethral stricture, and Reiter's Syndrome, are discussed. It appears as though there is a reasonable possibility that Reiter's Syndrome is a separate entity (or immunological sequela) rather than a complication.  相似文献

目的观察30分钟3千米的有氧运动训练方案对冠心病患者(非心绞痛型)IGF-1和CRP水平的影响。方法回顾我科2013年1~6月期间收治的符合入组条件的冠心病患者,按开始接受冠心病二级预防治疗已满2周、4周和9周的时间点,随机抽取符合本次试验的患者,并建议其返回医院,完善本次试验对应时间点的相关检测指标,作为对照组(A组);对我科2013年6~12月期间收治的符合入组条件的冠心病患者作为观察组(B组),给予每日30分钟3千米快步行走的运动康复方案。结果 B组患者运动满2周时的IGF-1水平较A组患者无显著性差异(P0.05);B组患者运动满4周和9周时的IGF-1水平较A组患者升高,但B组患者9周时的IGF-1水平较4周时的IGF-1水平无明显变化(P0.05);B组患者运动满2周、4周和9周时的CRP水平较A组患者无明显差异(P0.05);IGF-1水平和CRP水平之间未提示有相关性。结论 30分钟3千米快步行走的有氧运动方式改善了冠心病患者运动4周、9周后的IGF-1水平,但运动9周后的IGF-1水平较4周时,未见进一步提升;本次观察结果未显示该运动方案对CRP水平有影响,也未提示IGF-1水平与CRP水平之间有相关性。  相似文献
