To investigate the effects of exercise supervision on short- and longer-term moderate-vigorous physical activity (MVPA) participation.
Fifty-six Australian university employees completed a 16-week moderate-to-high intensity aerobic and resistance exercise intervention, and the international physical activity questionnaire (IPAQ) 15 months later. Participants received either personal (SUP; n = 21) or non-personal (NPS; n = 19) exercise supervision at an onsite facility or exercised offsite with no supervision (CON; n = 16).
A linear mixed model identified a significant group × time interaction effect for MVPA, with increases at 15-month follow-up for CON only. Pooled data suggested more participants completed ≥500 MET-minutes of weekly MVPA at 16 weeks (66%) and 15-month follow-up (68%) compared to baseline (54%).
A comprehensive health and fitness assessment and individually tailored exercise without personal supervision may promote ongoing MVPA.
探讨运动监督对短期和长期中等至剧烈体力活动（MVPA）参与的影响。
56 名澳大利亚大学员工完成了 16 周的中高强度有氧运动和抗阻运动干预，15 个月后再次使用国际体力活动问卷（IPAQ）进行评估。参与者在现场接受个人（SUP；n=21）或非个人（NPS；n=19）运动监督，或在现场外进行无监督的运动（CON；n=16）。
线性混合模型确定了 MVPA 的显著组间时间交互效应，仅在 15 个月随访时 CON 组有增加。汇总数据表明，与基线相比，更多的参与者在 16 周（66%）和 15 个月随访（68%）时完成了每周≥500 MET-min 的 MVPA，而在基线时仅为 54%。
全面的健康和健身评估以及无需个人监督的个体化运动计划可能会促进持续的 MVPA。
