There are existing measures of exercise motives (what people want from exercise), but corresponding measures of gains (what people get) are needed, because motives and gains could influence each other and together influence other variables. An exercise motives and gains inventory (EMGI) was developed by creating gains scales to complement existing Exercise Motivations Inventory 2 scales. Confirmatory factor analyses of EMGI items established that items reflected their intended constructs; and that motive and gain constructs were distinct. Exploratory structural equation modeling of EMGI scales established that the higher-order structures of motives and gains were somewhat different: Appearance motive was associated with weight management, whereas appearance gain was associated with health and fitness. Paired-sample t-tests established that gains were less than motives in some instances (ill-health avoidance, positive health), and greater in others (e.g., affiliation, challenge). The EMGI can be used to investigate the consequences and causes of motives and gains. 相似文献

Abstract The degree of contribution to performance of the vertical jump by leg components plantar flexors, knee extensors, and hip extensors was determined experimentally and tested by analysis of covariance. One control and four experimental groups from 100 college men at Brigham Young University were randomly assigned to varying muscle strengthening programs for 8 weeks. Initial and final vertical jump tests and strength measures were administered. Gains in the vertical jump significant beyond the .05 level were registered by experimental groups which strengthened knee and/or hip extensors. Control and plantar flexor strengthening groups did not register significant jump gains. Each experimental group registered significant isotonic strength gains in the programed muscle groups. 相似文献

Abstract Students (N = 104) enrolled in four low fitness, one middle fitness, and one high fitness class in basic physical education classes at the University of Connecticut participated in a 4-week program of isometric exercises done with an adjustable nylon belt which was stabilized against various body segments. Low, middle, and high fitness classes were compared in the amount of improvement made in the 5 items in which significant gains had been made. The MWF classes which did 30 min. of isometric exercises for 12 class meetings were compared to the TTh classes which met for 8 class meetings and which did the same isometric exercise program and in addition did stretching exercises and ran a mile. When all groups were treated together, mean gains of 1.1 in. in the vertical jump, .74 sec. in the agility run, .17 sec. in the 30-yd. dash, 151.9 lb. in the leg lift, and 57.0 lb. in the back lift were made. These were all significant at the 0.005 to the 0.0005 level. Small but significant gains were made in right and left grip, the Fait endurance hang, and the 380-yd. run. The low fitness classes made greater improvements in the leg lift, the vertical jump, and the agility run than did the middle or high fitness groups. The high fitness class made greater improvements in the back lift and in the 30-yd. dash than did the low or middle fitness classes. The classes which did only isometric exercises for a half-hour three times each week for 4½ weeks made greater mean gains in the vertical jump, the agility run, the 30-yd. dash and the back lift than did the classes which met for 60-min. periods twice each week for 4½ weeks and did stretching exercises and running in addition to the isometric exercises. However, the latter made greater gains in the leg lift. 相似文献

本文对我国体育市场秩序的本质与作用进行了理论研究。研究认为:体育市场秩序在本质上是一种利益和谐、竞争适度、收益共享的资源配置状态和利益关系体系。因此,治理体育市场秩序的重心不应当是目前流行的简单的体育行政处罚或道德教化,而应当是在必要的体育法制建设、体育行政管理及体育制度完善的基础上,进行利益关系的重构和协调,消除各种体育经济主体之间、政府之间和政府与各种社会经济主体之间的利益冲突,从而实现利益和谐及利益和谐条件下体育市场秩序的和谐。 相似文献

Arab football clubs have been playing in the Israeli football league since the establishment of the State of Israel (1948) and have continued to do so to date, with a few clubs in the premier league. While Arab football clubs expanded to almost every Arab village and town, football became highly popular among the Israeli Arabs. However, because of the Arabs’ minority status in Israel and the ongoing conflict between the State of Israel and the Palestinians (also with certain Arab states) football assumed a definite instrumentality for the Arab-Palestinian citizens of Israel. This paper deals precisely with this issue: what did/does football do for the Arabs in Israel? Who gained/gains from the existence and the participation of Arab clubs in the Israeli football league? Certain gains can definitively be discerned and divided into three levels: the individual player that benefited from socio-economic mobility, the local club that became a hub of ethnic-national identification for many residents, and the entire Arab community in Israel whose internal debate about self-identification was encouraged by football and was instrumental both for integration and protest regarding the State of Israel, which has been dominated by the Jewish majority. 相似文献

Estimating changes in hydration status from changes in body mass: considerations regarding metabolic water and glycogen storage 总被引：1，自引：0，他引：1
The potential for imprecision in the estimation of hydration status from changes in body mass has been outlined previously but the equations derived from these derivations appear inconsistent. Reconciliation of body mass loss in terms of sweat loss and effective body water loss is possible from specific equation sets provided that gains and losses of both body mass and water used in the derivation of sweat loss and to derive effective body water loss are in inclusive equation sets. This is obligatory so that mass and water changes as quantifiable determinants are consistent with both internal processes and external gains and losses. Thus, body mass loss, substrate oxidation, metabolic water, and all the terms used in simultaneous equation sets have to be reconciled not only as identical variables but mathematically balance exactly. The revised equation for effective body water loss given here is different from that originally proposed. Metabolic water is part of body mass loss corrected for substrate oxidation, fluid ingestion, and respiratory water to derive sweat loss and it may not be justified to also include water associated with glycogen as releasable bound water. Accordingly, our calculated effective body water loss is substantially a greater loss than originally supposed but clearly still less than the simple balance between mass loss and fluid ingested. 相似文献
