目的研究长柄曲棍球与棒球球体的物理特性,探讨长柄曲棍球球体造成伤害的潜在风险。方法实验球体为长柄曲棍球与棒球各12颗,检测前皆通过24 h环境控制,使球体温湿度一致,再进行长柄曲棍球与棒球球体质量、圆周、压缩值与恢复系数等物理特性的测量,以独立样本t检验比较长柄曲棍球与棒球的差异。结果长柄曲棍球球体质量为(144.65±0.29)g,圆周为(19.97±0.02)cm,压缩值为(91.76±1.23)kg,恢复系数为(0.633±0.011);棒球球体重量为(146.12±0.45)g,圆周为(23.20±0.06)cm,压缩值为(124.76±1.68)kg,恢复系数为(0.528±0.005)。长柄曲棍球的质量、圆周与压缩值均显著小于棒球,恢复系数则显著大于棒球(P<0.05)。结论长柄曲棍球的物理特性虽符合国际标准规范,但长柄曲棍球与棒球一样都有造成严重运动伤害的风险。建议可依据年龄与技巧进行球体分级,给予不同等级的选手使用,以降低运动受伤风险。 Objective To study the physical characteristics of long-handled hockey sticks and baseball balls and to explore the potential risk of long-handled hockey stick ball injuries. Methods The experiment sphere consisted of 12 long-handled hockey sticks and baseballs. All of them were controlled by 24 h environment before the test, which made the temperature and humidity of the sphere consistent. The physical properties of the long-handled hockey stick and the baseball were measured, such as mass, circumference, compression value and recovery coefficient , To compare the differences between long-handled hockey and baseball with an independent sample t-test. Results The ball mass of long-handled hockey ball was (144.65 ± 0.29) g, the circumference was (19.97 ± 0.02) cm, the compression value was (91.76 ± 1.23) kg, the recovery coefficient was (0.633 ± 0.011), the weight of baseball ball was (146.12 ± 0.45) ) g, the circumference was (23.20 ± 0.06) cm, the compression value was (124.76 ± 1.68) kg, and the recovery coefficient was (0.528 ± 0.005). The quality, circumference and compression values ​​of long-handled hockey sticks were significantly smaller than that of baseballs, and the recovery coefficients were significantly greater than that of baseballs (P <0.05). Conclusion Although the physical properties of long-handled hockey meet international standards, long-handled hockey and baseball have the same risk of causing serious sports injuries. It is suggested that the ball may be graded according to age and skill and be used by different levels of players to reduce the risk of sports injuries.
