The aim of this study was to analyze the effects of resistance training (RT) performed with 1 or 3 sets per exercise on osteosarcopenic obesity (OSO) syndrome parameters in older women. Sixty-two older women (68.0 ± 4.3 years, 26.8 ± 4.4 kg/m2) participated in a 12-week RT program. Participants were randomly assigned into one of the three groups: two training groups that performed either 1 set (G1S, n = 21) or 3 sets (G3S, n = 20) 3 times weekly, or a control group (CG, n = 21). Body composition was assessed by dual X-ray absorptiometry, strength was evaluated by 1 repetition maximum testing. The G3S presented significantly higher strength changes than G1S. The changes for percentage of body fat were higher for G3S compared to G1S. There was no difference in skeletal muscle mass between G3S and G1S, however both training groups displayed greater increases in this outcome compared to CG. There was no effect for bone mineral density. The overall analysis indicated higher (P < 0.05) positive changes for G3S than G1S (composed Z-score: G3S = 0.62 ± 0.40; G1S = 0.11 ± 0.48). The results suggest that a 12-week RT period is effective to improve the risk factors of OSO, and that 3 sets induce higher improvements than a single set. 相似文献

The issue of sports mascot loyalty, especially to those mascots considered offensive, was investigated through fan identification theory, and applied to the mascot controversy at a large university in the United States. Replicating a previous university survey on the mascot question, a survey of current university students (N = 3616) revealed a strong relationship between mascot loyalty and fan identification, particularly related to one’s perceptions of ‘belonging to the university sports family’, and ‘associating with sports fans’ of the university. Other important findings include age differences and the marginalization of Asian-American fans. The implications and applications of these findings were discussed. 相似文献

This study assessed the validity of a tri-axial accelerometer worn on the upper body to estimate peak forces during running and change-of-direction tasks. Seventeen participants completed four different running and change-of-direction tasks (0°, 45°, 90°, and 180°; five trials per condition). Peak crania-caudal and resultant acceleration was converted to force and compared against peak force plate ground reaction force (GRF) in two formats (raw and smoothed). The resultant smoothed (10 Hz) and crania-caudal raw (except 180°) accelerometer values were not significantly different to resultant and vertical GRF for all running and change-of-direction tasks, respectively. Resultant accelerometer measures showed no to strong significant correlations (r = 0.00–0.76) and moderate to large measurement errors (coefficient of variation [CV] = 11.7–23.9%). Crania-caudal accelerometer measures showed small to moderate correlations (r = ? 0.26 to 0.39) and moderate to large measurement errors (CV = 15.0–20.6%). Accelerometers, within integrated micro-technology tracking devices and worn on the upper body, can provide a relative measure of peak impact force experienced during running and two change-of-direction tasks (45° and 90°) provided that resultant smoothed values are used. 相似文献

经济全球化是世界经济发展的一个客观过程,它是一股不以人们的意志为转移的巨大潮流,经济全球化在给各国带来空前发展机遇的同时,也给各国尤其是发展中国家带来了前所未有的挑战,面对经济全球化的机遇与挑战,我们必须认清本国在经济全球化过程中的地位,主动地接受世界市场的运行机制,按世界市场的规划办事,屏弃传统的“国家迷信”,不断地根据世界市场的变化调整国家的宏观经济调控政策,并且加强与世界市场中所有行为体的合作,只有这样,我们才能把握住历史发展的潮流,使自己立于不败之地。 相似文献

The Twenty‐first Century Learning in Natural History Settings Conference at the Smithsonian Institution, Washington, D.C. (2012) has been more influential than similar conferences, resulting in new work streams and international collaborations for the Learning Research and Evaluation team at the Natural History Museum, London (NHM). The conference offered a rare opportunity to discuss issues relevant to our unique workplace and to be surrounded by an instant peer group. Although the event itself brought personal and professional satisfaction, it is the impact of the conference on our institution that has been most fulfilling. The conference has enabled us to think bigger—to think about the sector as a whole and the role the NHM can play as a large national museum. 相似文献
