This study analysed the validity and reliability of a new optoelectronic device (Velowin) for the measurement of vertical displacement and velocity as well as to estimate force and mechanical power. Eleven trained males with Mean (SD) age = 27.4 (4.8) years, completed an incremental squat exercise test with 5 different loads (<30–90% of their 1?repetition maximum) while displacement and vertical velocity of the barbell were simultaneously measured using an integrated 3D system (3D motion capture system + force platform) and Velowin. Substantial to almost perfect correlation (concordance correlation coefficient = 0.75–0.96), root mean square error as coefficient of variation ±90% confidence interval ≤10% and good to excellent intraclass correlation coefficient = 0.84–0.99 were determined for all the variables. Passing and Bablock regression methods revealed no differences for average velocity. However, significant but consistent bias were determined for average or peak force and power while systematic and not proportional bias was found for displacement. In conclusion, Velowin, in holds of some potential advantages over traditionally used accelerometer or linear transducers, represents a valid and reliable alternative to monitor vertical displacement and velocity as well as to estimate average force and mechanical power during the squat exercise. 相似文献

Previous studies indicate that elastic resistance bands (ERB) can be a viable option to conventional resistance-training equipment (CRE) during single-joint resistance exercises, but their efficacy has not been established for several commonly used multiple-joint resistance exercises. Thus, we compared muscular activation levels in four popular multiple-joint exercises performed with ERB (TheraBand®) vs. CRE (Olympic barbell or cable pulley machines). In a cross-over design, men and women (n?=?29) performed squats, stiff-legged deadlifts, unilateral rows and lateral pulldown using both modalities. Multilevel mixed-effects linear regression analyses of main and interaction effects, and subsequent post hoc analyses were used to assess differences between the two resistance-training modalities. CRE induced higher levels of muscle activation in the prime movers during all exercises (p?<?.001 for all comparisons), compared to muscle activation levels induced by ERB. The magnitude of the differences was marginal in lateral pulldown and unilateral rows and for the erector spinae during stiff-legged deadlifts. In squats the quadriceps femoris activations were substantially lower for ERB. The differences between ERB and CRE were mostly observed during the parts of the contractions where the bands were relatively slack, whilst the differences were largely eliminated when the bands became elongated in the end ranges of the movements. We conclude that ERB can be a feasible training modality for lateral pulldowns, unilateral rows and to some extent stiff-legged deadlifts, but not for the squat exercise. 相似文献

应用常压缺氧试验观察润神口服液对小鼠耐缺氧能力的影响。结果显示注射心得安、1号口服液和2号口服液雌鼠的耐缺氧能力均极显著地高于生理盐水对照组(P<0.01)。注射心得安和1号口服液雄鼠的平均耐缺氧能力分别下降5.5%和13.6%,注射2号口服液的雄鼠则提高15.4%。说明2号口服液对雌雄小鼠的耐缺氧能力有更好的调理、平衡及提高作用。 相似文献

1932年4月29日在上海发生了震惊中外的虹口公园爆炸案。70多年过去了,有关此事的具体组织过程仍然各方说法不一,值得研究和注意。在日本投降之前,韩国临时政府负责人金九以及他领导的韩人爱国团只字不提此案与中国人的关系,是完全可以理解的。抗战胜利后,由于种种原因,金九写的《白凡逸志》对比事还语焉不详,因此,完全依据金九单方面的史料来研究虹口公园爆炸案的来龙去脉,至少是不完整的。 相似文献
