Quantify physical activity in healthy student athletes.
Cross-sectional survey.
Five Central Ohio schools during mass preparticipation physicals.
Three hundred sixty-five children between the ages 10 and 18 years.
Days per week of moderate to vigorous physical activity (MVPA), minutes per day of MVPA, and number of activities.
Minutes per week of MVPA.
One hundred eighty high school and 177 middle school subjects responded to the survey. There were 198 male and 162 female respondents. Mean age recorded 14.2 ± 1.7 years. There were no differences in activity volume based on sex. Mean minutes per week of MVPA reported 316.0 ± 231.0. High school subjects reported fewer activities than middle school cohort 2.7 ± 1.2 versus 3.2 ± 1.5 (P < 0.05).
Only 7% of respondents reported exercising 60 minutes daily. Twenty-seven percent of respondents met minutes per week (420 minutes of MVPA) by training in large volumes on fewer days. Surprisingly, this physically active population did not meet the national standards of daily MVPA. In addition, middle school athletes reported more variety of activities compared with high school athletes surveyed which reached statistical significance. Screening for daily physical activity is important in the athletic population because young athletes may not meet daily MVPA recommendations.
量化健康学生运动员的身体活动量。
横断面调查。
俄亥俄州中部五所学校,在大规模参与运动前体检期间。
365名年龄在10至18岁之间的儿童。
每周进行中度至剧烈身体活动(MVPA)的天数、每天MVPA的分钟数以及活动数量。
每周MVPA的分钟数。
180名高中生和177名初中生回应了调查。有198名男性和162名女性受访者。记录的平均年龄为14.2±1.7岁。基于性别的活动量没有差异。报告的每周MVPA平均分钟数为316.0±231.0。高中生报告的活动比初中生少,分别为2.7±1.2项与3.2±1.5项(P<0.05)。
只有7%的受访者报告每天锻炼60分钟。27%的受访者通过较少天数的大量训练达到了每周的分钟数(420分钟的MVPA)。令人惊讶的是,这个身体活跃的人群未达到每日MVPA的国家标准。此外,与接受调查的高中生相比,初中生运动员报告的活动种类更多,这具有统计学意义。在运动员群体中筛查日常身体活动很重要,因为年轻运动员可能未达到每日MVPA建议量。
