Effects of small-volume soccer and vibration training on body composition,aerobic fitness,and muscular PCr kinetics for inactive women aged 20-45

小规模足球运动和振动训练对20—45岁习惯久坐的女性身体成分、有氧适能、肌肉磷酸肌酸动力学的影响（英文）

Purpose： The present study investigated the effects of 16 weeks of small-volume, small-sided soccer training soccer group （SG, n = 13） and oscillating whole-body vibration training vibration group （VG, n = 17） on body composition, aerobic fitness, and muscle PCr kinetics in healthy inactive premenopausal women in comparison with an inactive control group （CO, n = 14）. Methods： Training for SG and VG consisted of twice-weekly 15-min sessions with average heart rates （HRs） of ～ 155 and 90 bpm respectively. Pre- and post-measurements of body composition （DXA）, phosphocreatine （PCr） on- and off-kinetics, and HR measurements during stand- ardised submaximal exercise were performed. Results： After 16 weeks of training in SG, fat percentage was lowered （p = 0.03） by 1.7%±2.4% from 37.5% ± 6.9% to 35.8% ± 6.2% and the PCr decrease in the quadriceps during knee-extension ramp exercise was attenuated （4% ± 8%, p = 0.04）, with no changes in VG or CO （time- group effect： p=0.03 and p = 0.03）. Submaximal exercise HR was also reduced in SG after 16 weeks of training （6%± 5% of HRmax, p = 0.01）. Conclusion： Short duration soccer training for 16 weeks appears to be sufficient to induce favourable changes in body composition and indicators of aerobic fitness and muscle oxidative capacity in untrained premenopausal women.

目标:本研究调查了16周小规模小场地足球训练(足球组(SG),n=13)和全身振动训练(振动组(VG),n=17)对身体组成、有氧适能、肌肉磷酸肌酸动力学在不常运动的绝经前期女性健康的影响,用另一组不常运动女性作为对照组(CO,n=14)。方法:足球组和振动组每周两次15分钟训练,平均心率(HR)分别约为155bpm和90bpm。测量运动前后身体组成、磷酸肌酸(PCr)启动和关闭时的动力学,以及标准化次极量运动时的心率水平。结果:足球组16周训练后,脂肪百分比下降了1.7%±2.4%(从37.5%±6.9%降低到35.8%±6.2%,p=0.03),膝伸展斜坡运动时股四头肌中磷酸肌酸水平下降得到缓解(4%±8%,p=0.04),但振动组和对照组没有改变。足球组16周训练后,次极量运动心率亦有降低(7%±5%HRmax,p=0.01)。结论:16周短期足球训练足以对未经训练的绝经前期女性在身体组成方面产生有益的改变,并能作为其有氧适能和肌肉氧化能力的指标。
