Milk has become a popular post-exercise recovery drink. Yet the evidence for its use in this regard comes from a limited number of investigations utilising very specific exercise protocols, and mostly with male participants. Therefore, the aim of this study was to investigate the effects of post-exercise milk consumption on recovery from a sprinting and jumping protocol in female team-sport athletes. Eighteen females participated in an independent-groups design. Upon completion of the protocol participants consumed 500 mL of milk (MILK) or 500 mL of an energy-matched carbohydrate (CHO) drink. Muscle function (peak torque, rate of force development (RFD), countermovement jump (CMJ), reactive strength index (RSI), sprint performance), muscle soreness and tiredness, symptoms of stress, serum creatine kinase (CK) and high-sensitivity C-reactive protein (hsCRP) were determined pre- and 24 h, 48 h and 72 h post-exercise. MILK had a effect in attenuating losses in peak torque (180/s) from baseline to 72 h (0.0 ± 10.0% vs. -8.7 ± 3.7%, MILK v CHO), and countermovement jump (-1.1 ± 5.2% vs. -10.4 ± 6.7%) and symptoms of stress (-13.5 ± 7.4% vs. -18.7 ± 11.0%) from baseline to 24 h. MILK had a and a effect on other peak torque measures and 5 m sprint performance at other timepoints but had an effect on 10 and 20 m sprint performance, RSI, muscle soreness and tiredness, CK and hsCRP. In conclusion, consumption of 500 mL milk attenuated losses in muscle function following repeated sprinting and jumping and thus may be a valuable recovery intervention for female team-sport athletes following this type of exercise.
牛奶已成为一种流行的运动后恢复饮品。然而,其在这方面的应用证据来自少数利用非常特定的运动方案进行的研究,而且主要涉及男性参与者。因此,本研究的目的是调查运动后饮用牛奶对女性团队运动运动员短跑和跳跃训练后恢复的影响。18 名女性参与了独立分组设计。在完成方案后,参与者分别饮用 500 毫升牛奶(MILK)或 500 毫升能量匹配的碳水化合物(CHO)饮料。肌肉功能(峰值扭矩、力量发展速率(RFD)、反跳跳(CMJ)、反应强度指数(RSI)、短跑性能)、肌肉酸痛和疲劳、应激症状、血清肌酸激酶(CK)和高敏 C 反应蛋白(hsCRP)在运动前和运动后 24 小时、48 小时和 72 小时进行测定。MILK 对峰值扭矩(180/s)从基线到 72 小时的下降有明显影响(0.0±10.0%比-8.7±3.7%,MILK 比 CHO),对反跳跳(-1.1±5.2%比-10.4±6.7%)和应激症状(-13.5±7.4%比-18.7±11.0%)从基线到 24 小时也有明显影响。MILK 对其他峰值扭矩测量和 5 米短跑成绩在其他时间点有显著影响,对 10 米和 20 米短跑成绩、RSI、肌肉酸痛和疲劳、CK 和 hsCRP 有中等影响。总之,饮用 500 毫升牛奶可以减轻女性团队运动运动员重复短跑和跳跃后的肌肉功能下降,因此可能是此类运动后运动员恢复的一种有价值的干预措施。
