许多青少年不符合中度至剧烈体力活动 (MVPA) 的公共卫生建议。在影响青少年 MVPA 的变量研究中，对运动的情感反应尚未得到充分研究。我们假设对剧烈运动有更积极情感反应的青少年会更活跃。青少年（N = 124；46% 男性）完成两项 30 分钟的锻炼任务（高于和低于通气阈值 [VT]），并佩戴 ActiGraph 加速计 6.5 +/- 0.7 天。在每项任务之前、期间和之后评估情感效价。低于 VT 的运动期间更积极的情感反应与更多地参与 MVPA 相关 (p < .05)。结果与以下假设一致：对运动有更积极情感反应的个体会参与更多 MVPA。为了促进青少年更多地参与 MVPA，项目的设计应促进运动期间的积极情感体验。
Many adolescents do not meet public health recommendations for moderate-to-vigorous physical activity (MVPA). In studies of variables influencing adolescent MVPA, one that has been understudied is the affective response to exercise. We hypothesized that adolescents with a more positive affective response to acute exercise would be more active. Adolescents (N = 124; 46% male) completed two 30-min exercise tasks (above and below the ventilatory threshold [VT]), and wore ActiGraph accelerometers for 6.5 +/- 0.7 days. Affective valence was assessed before, during, and after each task. A more positive affective response during exercise below the VT was associated with greater participation in MVPA (p < .05). The results are consistent with the hypothesis that individuals who have a more positive affective response to exercise will engage in more MVPA. To promote greater participation in MVPA among adolescents, programs should be designed to facilitate a positive affective experience during exercise.
