Multistage, ultra-endurance events in hot, humid conditions necessitate thermal adaptation, often achieved through short term heat acclimation (STHA), to improve performance by reducing thermoregulatory strain and perceptions of heat stress. This study investigated the physiological, perceptual and immunological responses to STHA prior to the Marathon des Sables. Eight athletes (age 42 ± 4 years and body mass 81.9 ± 15.0 kg) completed 4 days of controlled hyperthermia STHA (60 min·day?1, 45°C and 30% relative humidity). Pre, during and post sessions, physiological and perceptual measures were recorded. Immunological measures were recorded pre-post sessions 1 and 4. STHA improved thermal comfort (P = 0.02), sensation (P = 0.03) and perceived exertion (P = 0.04). A dissociated relationship between perceptual fatigue and Tre was evident after STHA, with reductions in perceived Physical (P = 0.04) and General (P = 0.04) fatigue. Exercising Tre and HR did not change (P > 0.05) however, sweat rate increased 14% (P = 0.02). No changes were found in white blood cell counts or content (P > 0.05). Four days of STHA facilitates effective perceptual adaptations, without compromising immune status prior to an ultra-endurance race in heat stress. A greater physiological strain is required to confer optimal physiological adaptations. 相似文献

This paper reports on a 16-week sport education (SE) unit with just over 70 year 5 students (M age = 10.04 years) in one United Kingdom school during the spring and summer terms and discusses students' SE experiences. Student interviews were conducted throughout the season and a questionnaire on different motivation aspects was administered prior to and before completing the SE season. We report and examine the data in relation to hypothesized influences on fun and enjoyment, including being part of a team, autonomy, and improving game play. The principal reasons SE may be more enjoyable than previous physical education lessons include the greater opportunities for autonomy, affiliation, and competition, plus perceived learning. 相似文献

The aims of the study were to determine those variables that significantly affect push-in execution and thereby formulate coaching recommendations specific to the push-in. Two 50 Hz video cameras recorded transverse and longitudinal views of push-in trials performed by eight experienced and nine inexperienced male push-in performers. Video footage was digitized for data analysis of ball speed, stance width, drag distance, drag time, drag speed, centre of massy displacement and segment and stick displacements and velocities. Experienced push-in performers demonstrated a significantly greater (p < 0.05) stance width, a significantly greater distance between the ball and the front foot at the start of the push-in and a significantly faster ball speed than inexperienced performers. In addition, the experienced performers showed a significant positive correlation between ball speed and playing experience and tended to adopt a combination of simultaneous and sequential segment rotation to achieve accuracy and fast ball speed. The study yielded the following coaching recommendations for enhanced push-in performance: maximize drag distance by maximizing front foot-ball distance at the start of the push-in; use a combination of simultaneous and sequential segment rotations to optimise both accuracy and ball speed and maximize drag speed. 相似文献

This investigation involved the surveying of school psychology practitioners (N = 291) to determine the possible existence of a relationship between administrative pressure to practice unethically and impaired occupational health, as manifested in elevated levels of burnout, job dissatisfaction, and intent to exit the workforce. Almost one‐third of participants claimed to have been pressured to behave unethically, with directives most commonly consisting of instructions to withhold recommendations for support services and to agree with inappropriate special education placement decisions. Practitioners who experienced administrative pressure reported higher levels of burnout, less satisfaction with their current position and the profession, and a greater desire to leave their job and the field of school psychology. The findings are presented within the context of current and projected shortages of practicing school psychologists. Implications for preventing burnout and promoting school psychologists’ occupational well‐being are discussed. 相似文献

A survey of 289 pastors from, three major denominations found that clergy demonstrate a relatively high level of gerontological knowledge in comparison with other reference groups, but that their concepts of aging are affected by a number of consistent stereotypes and inaccuracies that may negatively influence their ministry among older adults. This study addresses the major stereotypes identified by the Facts on Aging Quiz, summarizes gerontological education needs described by the respondents, and draws implications for gerontological training as part of seminary education. 相似文献
