Tomoko Aoyama et al.
We examined whether cardiorespiratory fitness (maximal oxygen uptake, VO(2)max) and muscular strength (grip strength) are associated with individual and clustered metabolic risk factors independently of abdominal adiposity in Japanese men (...
Effects of walking speed and step frequency on estimation of physical activity using accelerometers [0.03%]
步速和步频对加速仪估测身体活动的影响分析
Jonghoon Park,Kazuko Ishikawa-Takata,Shigeho Tanaka et al.
Jonghoon Park et al.
This study evaluated the accuracy of assessing step counts and energy costs under walking conditions altered by step frequency changes at given speeds using uni- (LC) and tri-axial accelerometers (AM, ASP). Healthy young men and women (n=18...
