目前的体力活动(PA)指南表明，在总运动量相同的情况下，中等强度(Mpa)和剧烈(VPA)PA提供类似的益处。本研究调查了自由生活的年轻人的身体成分和心肺适能与MPA和VPA的关系。总共对197名年轻人(52.8%为男性)进行了为期15个月的跟踪调查。通过双X射线吸收测量仪评估身体成分，并使用多传感器设备每3个月确定在不同PA强度下花费的时间。在基线和15个月的随访中，采用分级运动试验评估心肺功能。VPA的变化与心肺健康呈正相关，而MPA与体脂百分比有有益的关联。在超重/肥胖参与者中，MVPA发作和VPA与VO(2)峰值的关联相似。尽管MPA和VPA与整体健康呈正相关，但它们在关键健康参数上的相关性有所不同。
Current physical activity (PA) guidelines indicate that moderate-intensity (MPA) and vigorous intensity (VPA) PA provide similar benefits when total volume is equal. The present study examined the associations of MPA and VPA with body composition and cardiorespiratory fitness in free-living young adults. A total of 197 young adults (52.8 % male) were followed over a period of 15 months. Body composition was assessed via dual X-ray absorptiometry and time spent in various PA intensities was determined with a multi-sensor device every 3 months. Cardiorespiratory fitness was assessed with a graded exercise test at baseline and 15-months follow-up. Change in VPA was positively associated with cardiorespiratory fitness while MPA had beneficial associations with percent body fat. In overweight/obese participants the association with VO(2)peak was similar for MVPA bouts and VPA. Even though MPA and VPA have positive associations with overall health, their associations on key health parameters differ.
