The Italian government promoted social distancing, in which the suspension of any social event, suspension of all activities practiced in gyms, sports centers and their closure was ordered. The social distancing in the school environment and the use of strategies to limit viral infection are not very compatible with group motor activity and team sports. The aim of this study is to verify the effectiveness of a CrossFit program in order to mitigate the deficits in fitness caused by COVID-19 prevention measures and to evaluate the effects on self-efficacy in a group of young adolescents. Methodsː 30 healthy participants were randomly allocated into an intervention group (IG) that performed the 8 weeks CrossFit training program or control group (CG). Physical fitness tests (i.e., Squat, push-up, lunge, and 20 m run) and psychological measures Regulatory Emotional Self-Efficacy scale (RESE) were performed at baseline and after 8 weeks. Resultsː After 8 weeks, the intervention group showed significant improvements for all fitness tests ( < 0.0001). Additionally, higher scores for the RESE negative and positive ( < 0.0001) scales were found in the intervention group. No statistical differences were found in the control group except for the push up test. Conclusionsː the 8-week CrossFit intervention program could positively affect the general physical well-being and improve the emotional perceived self-efficacy in healthy adolescents.
意大利政府提倡保持社交距离，其中包括暂停任何社交活动、暂停所有在健身房、体育中心进行的活动，并下令关闭这些场所。在学校环境中保持社交距离以及使用策略来限制病毒感染与集体运动活动和团队运动不太兼容。本研究的目的是验证 CrossFit 计划的有效性，以减轻因 COVID-19 预防措施而导致的健康状况下降，并评估其对一群年轻青少年自我效能感的影响。方法：30 名健康参与者被随机分配到干预组（IG），该组进行 8 周的 CrossFit 训练计划，或对照组（CG）。在基线和 8 周后进行身体适应性测试（即深蹲、俯卧撑、弓步和 20 米跑）和心理测量调节情绪自我效能感量表（RESE）。结果：8 周后，干预组在所有身体适应性测试中均显示出显著改善（<0.0001）。此外，干预组的 RESE 负向和正向（<0.0001）量表得分更高。对照组除了俯卧撑测试外，其他测试均无统计学差异。结论：8 周的 CrossFit 干预计划可以积极影响健康青少年的整体身体舒适度，并提高他们的情绪自我效能感。
