OBJECTIVE
The objective of this pilot study was to determine the effect of a supervised short-term exercise trial on exercise adherence in a sample of African American males.
METHODS
We observed exercise adherence rates among a group of African American men in response to an exercise intervention. Exercise adherence was determined by dividing the total number of actual sessions attended by the total number of possible sessions (12 sessions). A participant was classified as an adherer if they completed 9 out of 12 exercise sessions (75%).
RESULTS
Seventy-one percent of the study participants (12/17) completed at least 75% of the study sessions and therefore adhered to the study protocol. Among the adherers, 7 out of 12 (58%) had adherence rates of 100%. Five participants withdrew from the exercise group due to lack of time and lack of interest.
CONCLUSION
Exercise adherence rates among African-American men in this study were favorable during this supervised exercise intervention and were comparable to adherence rates observed in other supervised exercise interventions. Recommendations based on this pilot study are provided to reduce participant withdrawal and to inform future large-scale studies.
目的
本初步研究旨在确定监督短期运动试验对非裔美国男性样本中运动依从性的影响。
方法
我们观察了一组非裔美国男性对运动干预的运动依从率。运动依从性通过将实际参加的总次数除以可能参加的总次数（12 次）来确定。如果参与者完成了 12 次运动中的 9 次（75%），则将其归类为依从者。
结果
研究参与者的 71%（12/17）完成了至少 75%的研究课程，因此遵守了研究方案。在依从者中，有 7 人（58%）的依从率达到 100%。由于时间和缺乏兴趣，5 名参与者退出了运动组。
结论
在这项监督性运动干预中，非裔美国男性的运动依从率是有利的，与其他监督性运动干预中观察到的依从率相当。根据这项初步研究提出了建议，以减少参与者的退出并为未来的大规模研究提供信息。
