隐性利益与体育利益格局演化分析框架(下)——当代中国体育利益格局演化的简要分析

本文基于所构建的体育利益格局演化分析框架,探讨当代中国体育发展过程中体育利益演化的热点领域,分析了体制变迁对体育情景的影响,以及不同体育利益群体的演化及其委托代理问题。研究表明:制度变迁引发的体育情景的改变是重要的外在因素;体育利益格局演化中的委托代理问题的实质,是利益群体中存在委托代理问题,强化对代理人行为规制是解决问题的关键。就如何引导体育利益格局向符合绝大多数人利益的正确方向演化,提出了建议。     

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.     

The fourth dimension: A motoric perspective on the anxiety–performance relationship

This article focuses on raising concern that anxiety–performance relationship theory has insufficiently catered for motoric issues during, primarily, closed and self-paced skill execution (e.g., long jump and javelin throw). Following a review of current theory, we address the under-consideration of motoric issues by extending the three-dimensional model put forward by Cheng, Hardy, and Markland (2009) (‘Toward a three-dimensional conceptualization of performance anxiety: Rationale and initial measurement development, Psychology of Sport and Exercise, 10, 271–278). This fourth dimension, termed skill establishment, comprises the level and consistency of movement automaticity together with a performer's confidence in this specific process, as providing a degree of robustness against negative anxiety effects. To exemplify this motoric influence, we then offer insight regarding current theories’ misrepresentation that a self-focus of attention toward an already well-learned skill always leads to a negative performance effect. In doing so, we draw upon applied literature to distinguish between positive and negative self-foci and suggest that on what and how a performer directs their attention is crucial to the interaction with skill establishment and, therefore, performance. Finally, implications for skill acquisition research are provided. Accordingly, we suggest a positive potential flow from applied/translational to fundamental/theory-generating research in sport which can serve to freshen and usefully redirect investigation into this long-considered but still insufficiently understood concept.     

陕西省城市“弱势群体”健身状况的调查研究

对陕西省城市弱势群体参与健身活动和身体健康状况进行抽样调查。结果显示陕西省城市弱势群体的健康状况极差 ,健身意识不强、健身活动太少是其主要原因。提出了强化对弱势群体的救助和关注 ,不能仅限于生活上的关心、经济上的资助 ,还应关心他们的体质与健康 ,支持他们参与健身活动。
