This 6‐week pilot study aimed to investigate the feasibility, perceived efficacy, and participation perspectives of a university campus stair climbing‐based exercise snack (ES) intervention and to compare it to moderate‐intensity continuous training (MICT). Healthy, young, inactive adults (age: 21.6 ± 2.3 years, BMI: 22.5 ± 3.6 kg/m2) were randomly assigned to three groups (ES, MICT, and Control [CON]). ES (n = 14, 6 females) and MICT (n = 13, 9 females) groups performed three sessions per week over 6 weeks, while the control group (n = 15, 9 females) maintained their habitual lifestyle. ES involved 3 × ~30 s ‘all‐out’ stair‐climbing (6 flights, total 126 steps and 18.9 m elevation) bouts separated by > 1 h rest, and MICT involved 40 min stationary cycling at 60%–70% HRmax. Mixed linear effect models were used to explore within and between‐group differences, and the change in magnitude was determined using mean difference (MD), 95% confidence interval (CI), and Cohen's d effect size. Fourteen participants also completed post‐intervention semi‐structured interviews. Retention rates of 93% (ES, 14/15), 93% (MICT, 13/14), and 100% (CON, 15/15) were achieved from baseline to post‐assessments, with compliance (participants' attendance to scheduled ES sessions) of 97% (733/756 sessions) and 93% (217/234 sessions) in ES and MICT, respectively. No significant differences were found between ES and MICT for future intentions (4.8 ± 1.4 and 5.0 ± 0.9), enjoyment (PACES, 89.0 ± 16.4 and 94.5 ± 11.9), and satisfaction. A significant group × time interaction was found in the quality of life and perceived stress. ES and MICT significantly increased the quality of life by 8% (MD = 5.5 [95% CI = 0.3, 10.7], Cohen's d = 0.64) and 6% (MD = 4.6 [95% CI = 0.9, 8.2], Cohen's d = 0.88) compared to baseline, whereas CON experienced a significant decrease (MD = −7.9 [95% CI = −14.4, −1.6], Cohen's d = 0.56). ES significantly decreased perceived stress by 7% (MD = −4.6 [95% CI = −8.9, −0.3], Cohen's d = 0.58), while MICT (MD = 2.0 [95% CI = −0.1, 4.1], Cohen's d = 0.28) and CON (MD = −2.4 [95% CI = −6.1, 1.3], Cohen's d = 0.22) had no significant effects. The majority (12/14) of participants generally demonstrated positive attitudes toward participation in ES and found it easier than expected while highlighting enablers, barriers, and future recommendations. Stair climbing‐based ES could be integrated into the campus setting, appeared feasible, and was similar to MICT regarding future intentions, enjoyment, and satisfaction. Both ES and MICT might induce relevant positive effects on the quality of life, and ES demonstrated greater benefits compared to MICT or CON for reducing perceived stress. Interviews provided positive insights into fostering adherence to ES among university students.

将基于爬楼梯的运动零食整合到校园中对不活跃的年轻人的可行性、感知效能和参与前景的影响：一项随机混合方法试点研究


这项为期 6 周的试点研究旨在调查大学校园基于爬楼梯的运动零食 （ES） 干预的可行性、感知疗效和参与前景，并将其与中等强度持续训练 （MICT） 进行比较。健康、年轻、不活跃的成年人 （年龄：21.6 ± 2.3 岁，BMI：22.5 ± 3.6 kg/m2） 被随机分配到三组 （ES、MICT 和对照 [CON]）。ES （n = 14， 6 名女性） 和 MICT （n = 13， 9 名女性） 组在 6 周内每周进行 3 次治疗，而对照组 （n = 15， 9 名女性） 保持其习惯性生活方式。ES 涉及 3 × ~30 秒的“全力以赴”爬楼梯（6 次飞行，共 126 个台阶和 18.9 m 海拔）回合，间隔 > 1 小时休息，MICT 涉及 40 分钟的固定自行车，最大心率为 60%–70%。混合线性效应模型用于探索组内和组间差异，并使用平均差 （MD） 、 95% 置信区间 （CI） 和 Cohen 的 d 效应大小确定幅度的变化。14 名参与者还完成了干预后的半结构化访谈。从基线到后评估，保留率为 93%（ES，14/15）、93%（MICT，13/14）和 100%（CON，15/15），依从性（参与者参加预定的 ES 会议）分别为 97%（733/756 节）和 93%（217/234 节）ES 和 MICT。ES 和 MICT 在未来意图 （4.8 ± 1.4 和 5.0 ± 0.9）、享受 （PACES，89.0 ± 16.4 和 94.5 ± 11.9）和满意度方面没有显着差异。在生活质量和感知压力方面发现了显着的群体×时间交互。ES 和 MICT 显著提高了生活质量 8% （MD = 5.5 [95% CI = 0.3， 10.7]，Cohen 的 d = 0.64）和 6% （MD = 4.6 [95% CI = 0.9， 8.2]，Cohen 的 d = 0。88），而 CON 显着降低 （MD = -7.9 [95% CI = -14.4， -1.6]，Cohen 的 d = 0.56）。ES 显著降低了 7% 的感知压力 （MD = -4.6 [95% CI = -8.9， -0.3]，Cohen 的 d = 0.58），而 MICT （MD = 2.0 [95% CI = -0.1， 4.1]，Cohen 的 d = 0.28）和 CON （MD = -2.4 [95% CI = -6.1， 1.3]，Cohen 的 d = 0.22）没有显著影响。大多数 （12/14） 参与者普遍对参与 ES 表现出积极的态度，并发现它比预期的要容易，同时强调了推动因素、障碍和未来的建议。基于爬楼梯的 ES 可以整合到校园环境中，似乎是可行的，并且在未来的意图、享受和满意度方面与 MICT 相似。ES 和 MICT 都可能对生活质量产生相关的积极影响，与 MICT 或 CON 相比，ES 在减少感知压力方面显示出更大的益处。访谈为培养大学生对 ES 的依从性提供了积极的见解。
