我国6省市不同年龄群体参与体育旅游现状分析 总被引：2，自引：0，他引：2
对我国6省市不同年龄群体参与体育旅游的现状进行了调研，结果发现：不同年龄群体体育旅游需求、动机和消费水平有着显著不同。16～20岁、21～25岁和70岁以上的3个年龄段群体更希望出游的时候不经旅行社安排。在旅游伴侣的选择上，除了16～20岁、21～25岁和26～30岁这3个年龄段群体首选是希望与好朋友一起旅游外，其他各年龄段群体都首选希望能与家庭成员一起出游。年龄小的喜欢野营、游泳、滑雪、漂流、森林探险、潜水、攀岩、滑翔等，而年龄大者更加喜欢垂钓、远足等体育旅游活动。少年儿童以娱乐为主要动机，青年人以寻求刺激为主要动机，中年人主要以休闲为主要动机，老年人以健身为主要动机。在对体育旅游的认知上，16～20岁、21～25岁、26～30岁3个年龄段明显高于其他年龄段；各年龄段人群消费最多的在200元以上或5～100元。 相似文献

The aims of the present study were to assess the maximal oxygen uptake and body composition of adult Chinese men and women, and to determine how these variables relate to age. The cross-sectional sample consisted of 196 men and 221 women aged 20 - 64 years. Maximal oxygen uptake (VO2max) was determined by indirect calorimetry during a maximal exercise test on an electrically braked cycle ergometer. The correlations between VO2max and fat mass were -0.52 in men and -0.58 in women. Linear regression defined the cross-sectional age-related decline in VO2max as 0.35 ml kg(-1) min(-1) year(-1) in men and 0.30 ml kg(-1) min(-1) year(-1) in women. Multiple regression analysis showed that more than 50% of this cross-sectional decline in VO2max was due to fat mass, lean mass, and age. Adding fat mass and lean mass to the multiple regression models reduced the age regression mass from 0.35 to 0.24 ml kg(-1) min(-1) year(-1) in men and from 0.30 to 0.15 ml kg(-1) min(-1) year(-1) in women. We conclude that age, fat mass, and lean mass are independent determinants of maximal oxygen uptake in Chinese adults. 相似文献

There is evidence from previous cross-sectional studies that high volumes of certain sports, including running, swimming and cycling, may have a negative impact on bone mineral density. The aim of the present study was to evaluate prospectively the effects of high athletic training in individuals who engage in high volumes of all three of these activities (triathletes). Bone mineral density for the total body, arms and legs was determined by dual-energy X-ray absorptiometry in 21 competitive triathletes (9 men, 12 women) at the beginning of the training season and 24 weeks later. Age, body mass index, calcium intake and training volume were also recorded to examine potential mediators of bone mineral density change. Men had greater bone mineral density at all sites than women. No significant changes were observed over the 24 weeks for either total body or leg bone mineral density. Bone mineral density in both arms increased by approximately 2% in men (P < 0.03), but no change was observed for women. Change in bone mineral density at all sites was unrelated to age, body mass index, calcium intake and training volume. The results suggest that adverse changes in bone mineral density do not occur over the course of 6 months of training in competitive triathletes. 相似文献

A uniform measure of the gender-related differential performance of female and male Olympic and World champions is proposed: relative power output applied to the environment. Laws of physics are employed to derive equations for estimating relative power output. In previous controlled laboratory studies, equally trained male and female athletes were shown to have a relative power output not significantly different from relative lean body mass. As to the estimated power output for 32 Olympic and World championship events contested between 1976 and 2004, eight in running, four in speed skating, three in jumping, twelve in swimming and five in rowing: 100% of the 32 event mean percentage differences in power output and 96% of the 411 event percentage differences in power output are within one standard deviation of the appropriate lean body mass percentage difference, consistent with equality of training. For 1952-1972, significantly higher percentage differences in power output are estimated in running and swimming compared with 1976-2004, consistent with women being less well trained than men during that earlier period. It is noted that efforts in recent years to provide equality of opportunity for female athletes coincide with equalization of estimated relative power output in competition with the relative lean body mass. 相似文献

为探讨冰上运动项目对男大学生身体成分和骨密度的影响,采用韩国ZEUS9.9身体成分分析仪和法国Osteospace MEDI LINK超声骨量测量仪,分别对体育院校2010～2012级冰上运动专项的男大学生和没有运动专项的男大学生进行身体成分和骨密度的测量,并对实验数据进行统计学的分析与比较。结果显示,冰上运动专项男大学生左右腿肌肉含量、基础代谢率显著高于对照组（P＜0.05）,骨密度显著低于对照组大学生（P＜0.05）,这可能与调查对象的生活方式、饮食习惯、训练年限、运动水平以及冰上运动项目的教学内容有关。建议冰上运动专项男大学生改变不良生活方式、均衡饮食,适当调整运动训练方案,加强下肢的力量训练,提高运动成绩。 相似文献

骨密度的测定方法及影响因素 总被引：5，自引：0，他引：5
介绍骨密度测量的常用方法,并系统划分影响骨密度的因素。判断骨密度与年龄的关系,为青少年的年龄推断提供依据,得出骨密度随着年龄的增长而出现与年龄相关的骨质量减少。根据测量青少年的骨密度来解释为什么男孩在青春期后期比女孩发育得快;特别对女性进行调查发现,体重与瘦组织和脂肪组织在男女各个部位的骨密度都有一定的相关性;体育锻炼对其骨质量峰值期和衰老下降期的影响及运动负荷与骨质量的关系,发现女性在绝经后期骨质量快速下降。老年退行性骨质量丢失和绝经后骨质量丢失的综合效应以及峰值骨质量低于男性的特点,使得老年妇女骨质疏松发生的危险性高于任何人,雌激素水平低下是长期的剧烈运动训练引起骨密度偏低的主要原因。 相似文献

BackgroundWe compared body mass index (BMI), body fat, and skeletal muscle mass between (1) a mixed-sex nonathletic cohort of people with patellofemoral pain (PFP) and pain-free people, and (2) a nonathletic cohort of people with PFP and pain-free people subgrouped by sex (i.e., men and women with PFP vs. pain-free men and women).MethodsThis cross-sectional study included 114 people with PFP (71 women, 43 men) and 54 pain-free controls (32 women, 22 men). All participants attended a single testing session to assess body composition measures, which included BMI, percentage of body fat (%BFBioimpedance), and skeletal muscle mass (both assessed by bioelectrical impedance analysis), and percentage of body fat (%BFSkinfold) (assessed by skinfold caliper analysis). A one-way univariate analysis of covariance (age and physical activity levels as covariates) was used to compare body composition measures between groups (i.e., PFP vs. pain-free group; women with PFP vs. pain-free women; men with PFP vs. pain-free men).ResultsWomen with PFP presented significantly higher BMI, %BFBioimpedance, and %BFSkinfold, and lower skeletal muscle mass compared to pain-free women (p ≤ 0.04; effect size : ‒0.47 to 0.85). Men with PFP and men and women combined had no differences in BMI, %BFBioimpedance, %BFSkinfold, and skeletal muscle mass compared to their respective pain-free groups (p > 0.05).ConclusionOur findings indicate that BMI and body composition measures should be considered as part of the evaluation and management of people with PFP, especially in women, who have demonstrated higher BMI and body fat and lower skeletal muscle mass compared to pain-free controls. Future studies should not assess body composition measures in a mixed-sex population without distinguishing men participants from women participants. 相似文献
