河南省新乡市高校体育教师家庭体育消费现状调查研究

文章通过问卷调查法对新乡市五所高校体育教师的家庭体育消费现状进行研究,结果表明体育教师具有较合理的消费观念,消费方式以实物型消费为主,并具有逐步向观赏型和参与型体消费发展的趋势。     

高校体育消费市场的开发策略

体育消费是现代生活消费的一部分,我国各地高校相对集中的特点形成高校体育消费市场的可开发性,扩大体育人口,刺激体育消费;细分消费市场,满足不同消费群体需求;利用网络信息的宣传,提高消费意识是开发高校体育消费市场的策略。     

我国体育产业发展的双重阻力

我国GDP水平偏低，导致大众体育消费的有效消费不足；体育产业基础薄弱，体育产业结构不合理；体育人口众多与设施场地总量不足的矛盾：是我国体育产业发展的客观阻力。政府在体育产业中的职能定位存在偏差，职能转变缓慢，体育消费市场的实物消费远远大于体育劳务消费，则是我国体育产业发展的主观阻力。提出了在双重阻力作用下我国体育产业发展的思路。     

休闲体育消费动机对行为意愿的影响:休闲涉入与体验质量的双重中介效应

为深入探究消费动机对休闲体育消费行为意愿的影响,以及休闲涉入、体验质量在此过程中的双重中介效应,采用文献资料、因子分析、结构方程等方法,构建了休闲体育消费结构方程模型。实证检验结果显示,消费动机、休闲涉入、体验质量对休闲体育消费行为意愿具有显著的正向影响,休闲涉入、体验价值在消费动机对行为意愿的影响过程具有双重中介效应。研究证实,休闲体育消费行为意愿生成受多重要素驱动,为充分发挥消费动机的直接效应及休闲涉入、体验质量的双重中介作用,应从适度引导消费动机、加深休闲涉入程度、增强体验质量感知等层面,提出休闲体育消费优化方案,为有效满足民生需要、推动休闲体育消费业态健康发展提供理论支撑与现实指导。     

转型期我国有效体育需求不足问题研究

运用问卷调查及资料分析的方法研究转型期我国有效体育需求发展的水平及社会经济环境。结果表明，转型期虽然我国的有效体育需求水平呈总体上升趋势，但体育消费额占居民收入和消费总支出的比例还很小，整个体育产业对GDP的贡献是很有限的。加快完善社会保障体制的步伐，努力提高低收入者的可支配收入，增强居民的体育消费意识，完善体育市场服务体系，政府运用税收手段调节体育商品供给是提高我国有效体育需求的有效手段。     

成都市武术健身消费需求研究

文章运用问卷调查和数理统计的方法,对成都市武术健身消费需求现状进行研究后认为:目前成都市武术健身消费水平不高,需求较少,受到消费者基本状况、消费者对武术的偏好度、消费者所能接受的武术消费品的价格等相关因素综合作用的影响。     

对赣州市社区体育现状的调查与分析

采用问卷调查、文献资料调研、访谈等方法 ,就赣州市社区体育的现状进行调查研究 ,旨在系统、全面地了解赣州市社区体育的现状并发现存在的主要问题 ,为进一步深化赣州市社区体育改革和促进我国经济欠发达地区特别是革命老区社区体育向纵深方向发展提供依据。研究表明 :赣州市体育场 (馆 )设施匮乏 ,经费短缺 ,社区体育组织、制度、立法不够完善和健全等外在客观条件是居民参加社区体育活动的主要障碍因素。建议通过多种渠道和方式加大对社区体育的资金投入 ,不断健全和完善有关法规、制度等 ,改变居民参加社区体育活动明显不足的现状 ,促进社区体育的健康、可持续发展     

The Hit & Turn Tennis Test: An acoustically controlled endurance test for tennis players

Abstract

This study was conducted to validate and evaluate the “Hit & Turn Tennis Test”, an acoustically progressive on-court endurance test for tennis players. Ninety-eight competitive tennis players (53 males, 45 females) of different age groups participated in the study. For validation, the adult male players completed three Hit & Turn tests, one on a clay court and two on a carpet surface, a tennis-specific ball machine test and an incremental treadmill run in a randomized order. A stronger correlation between maximal performance (r = 0.81, P < 0.01) and maximal oxygen uptake (r = 0.96, P < 0.01) was observed between the Hit & Turn test and the ball machine test, than between the Hit & Turn test and the treadmill test. For test–retest, we found a significant correlation between maximal performance on the same (r = 0.83, P < 0.01) and on different surfaces (r = 0.74, P < 0.01). During test evaluation, maximal performance was higher in males than in females (P < 0.01) and increased by consecutive age group in boys (P < 0.01) but not in girls (P = 0.97). In conclusion, Hit & Turn maximum test performance can be recommended as a valid and reliable indicator for tennis-specific endurance.     

Physiological and biomechanical responses to walking underwater on a non-motorised treadmill: effects of different exercise intensities and depths in middle-aged healthy women

Abstract

Non-motorised underwater treadmills are commonly used in fitness activities. However, no studies have examined physiological and biomechanical responses of walking on non-motorised treadmills at different intensities and depths. Fifteen middle-aged healthy women underwent two underwater walking tests at two different depths, immersed either up to the xiphoid process (deep water) or the iliac crest (shallow water), at 100, 110, 120, 130 step-per-minute (spm). Oxygen consumption (VO₂), heart rate (HR), blood lactate concentration, perceived exertion and step length were determined. Compared to deep water, walking in shallow water exhibited, at all intensities, significantly higher VO₂ (+13.5%, on average) and HR (+8.1%, on average) responses. Water depth did not influence lactate concentration, whereas perceived exertion was higher in shallow compared to deep water, solely at 120 (+40%) and 130 (+39.4%) spm. Average step length was reduced as the intensity increased (from 100 to 130 spm), irrespective of water depth. Expressed as a percentage of maximum, average VO₂ and HR were: 64–76% of peak VO₂ and 71–90% of maximum HR, respectively at both water depths. Accordingly, this form of exercise can be included in the “vigorous” range of exercise intensity, at any of the step frequencies used in this study.     

Matching of Male and Female Subjects Using VO2 max

Abstract

We compared cardiorespiratory responses to exercise on an underwater treadmill (UTM) and land treadmill (LTM) and derived an equation to estimate oxygen consumption (VO₂) during UTM exercise. Fifty-five men and women completed one LTM and five UTM exercise sessions on separate days. The UTM sessions consisted of chest-deep immersion, with 0, 25, 50, 75, and 100% water-jet resistance. All session treadmill velocities increased every 3 min from 53.6 to 187.8 m·min^-1. Cardiorespiratory responses were similar between LTM and UTM when jet resistance for UTM was ≥ 50%. Using multiple regression analysis, weight-relative VO₂ could be estimated as: VO₂ (mLO₂·kg^-1·min^-1) = 0.19248 · height (cm) + 0.17422 · jet resistance (% max) + 0.14092 · velocity (m·min^-1) - 0.12794 · weight (kg) - 27.82849, R²= .82. Our data indicate that similar LTM and UTM cardiorespiratory responses are achievable, and we provide a reasonable estimate of UTM VO₂.
