Abstract

Background

Declining physical fitness and rising obesity in children call for effective interventions. Integrating kettlebell training into the classroom may provide a practical way to overcome existing barriers. This study examined its feasibility and effectiveness on second graders' motor performance, attention, and health.

Methods

Three classes (pre n = 61; post n = 47) performed daily 15-min kettlebell training for 7 weeks, while two classes (pre n = 33; post n = 31) served as controls. Pre/post assessments included mid-thigh pull, grip strength, countermovement jump, sprint, shuttle run, eye–hand coordination, side hop test, Flanker task, body composition, and blood pressure. Linear mixed models analyzed group differences, reporting Cohen's d and 95% confidence intervals (CIs).

Results

Small effects were observed in sprint (p = 0.01, d = 0.46, 95% CI [0.20–0.73], Δ = +3.6% [1.5–5.6]) and mid-thigh pull (p = 0.14, d = 0.28 [−0.08 to 0.64], Δ = +5.5% [−1.7 to 12.6]).

Implications for School Health Policy, Practice, and Equity

Fun, safe, and regular sessions with simple routines and age-appropriate exercises are required.

Conclusion

This classroom-integrated program is feasible and effective, particularly for enhancing lower-body strength and promoting movement during the school day.

课堂整合壶铃训练：对小学生运动表现、注意力和健康的影响。

背景：儿童体质下降和肥胖上升需要有效的干预措施。将壶铃训练融入课堂可能为克服现有障碍提供一种实用的方法。本研究探讨其对二年级学生运动表现、注意力及健康的可行性及有效性。方法：3个班级（n = 61，后n = 47）每天进行15分钟的壶铃训练，为期7周；2个班级（n = 33，后n = 31）作为对照。前/后评估包括大腿中部牵拉、握力、反向跳跃、冲刺、穿梭跑、手眼协调、侧跳测试、侧卫任务、身体成分和血压。线性混合模型分析组间差异，报告Cohen’s d和95%置信区间（ci）。结果:小影响被观察到在sprint (p = 0.01, d = 0.46, 95% CI(0.20 - -0.73),Δ= + 3.6%[1.5 - -5.6])和大腿拉(p = 0.14, d = 0.28(-0.08 - 0.64),Δ= + 5.5%[-1.7 - 12.6])。对学校健康政策、实践和公平的影响：需要有趣、安全、有规律的课程，包括简单的日常活动和适合年龄的练习。结论：该课堂整合方案是可行且有效的，特别是对于增强下半身力量和促进运动在上学日。试验注册：NCT06910085。
