The purpose of this study was to evaluate the relationship between adolescents' adherence to the 5-2-1-0 goals and the number of completed Progressive Cardiovascular Endurance Run (PACER) laps.
Participants included 1792 students aged 10 to 16 years who were randomly selected across 9 data collection periods between 2012 and 2014. The Survey of Physical Activity and Nutrition was used to measure time spent in physical activity and sedentary behavior, and dietary intake and the dependent variable was the number of PACER laps achieved. The Kruskal-Wallis test and pairwise post hoc comparisons were conducted.
Only 0.95% (N = 17) participants met all 4 goals outlined within the 5-2-1-0 guidelines. Whereas 10.04% met 3 (N = 180), 41.63% met 2 (N = 746), 34.99% met 1 (N = 627), and 12.39% did not meet any goals (N = 222). Pairwise comparisons indicated there were significant differences: between groups not meeting any of the 5-2-1-0 goals and other groups (meeting one goal [p = .000], 2 goals [p = .000], 3 goals [p = .000], and all 4 [p = .008]).
The positive relationship between PACER laps and adherence to the 5-2-1-0 goals suggests targeted and sequential behavioral changes may have positive implications on adolescents' cardiovascular fitness and body mass index.
本研究旨在评估青少年对5-2-1-0目标的依从性与完成渐进性心血管耐力跑(PACER)圈数之间的关系。
参与者包括1792名年龄在10至16岁之间的学生,他们在2012年至2014年的9个数据收集期内被随机选取。使用身体活动与营养调查来测量身体活动和久坐行为所花费的时间、饮食摄入量,因变量是完成的PACER圈数。进行了Kruskal-Wallis检验和两两事后比较。
只有0.95%(N = 17)的参与者符合5-2-1-0指南中列出的所有4个目标。而10.04%的人符合3个目标(N = 180),41.63%的人符合2个目标(N = 746),34.99%的人符合1个目标(N = 627),12.39%的人未符合任何目标(N = 222)。两两比较表明存在显著差异:在未符合任何5-2-1-0目标的组与其他组(符合1个目标[p = .000]、2个目标[p = .000]、3个目标[p = .000]和所有4个目标[p = .008])之间。
PACER圈数与对5-2-1-0目标的依从性之间的正相关关系表明,有针对性的、循序渐进的行为改变可能对青少年的心血管健康和体重指数产生积极影响。
