The purpose of this study was to investigate the degree of neuromuscular fatigue and recovery from fatigue, following handball training and handball matches at elite level. The focus was specifically on changes in physical performance when playing three matches over the course of 3 days, which simulates a sequence in international championships. Female players from the Norwegian national handball team were tested during a 5-day training camp (seven players) and a 3-day international tournament (eight players). Testing was done before and after training sessions and matches. Neuromuscular fatigue was measured as changes in voluntary isokinetic knee extensions, jump height in counter-movement jumps, and 20 m sprint time. The results showed a significant reduction by 2-6% in all three performance tests during the training camp and by 4-7% during the tournament (sprint and jump test) (P<0.05). Slow recovery was indicated by incomplete restoration of performance between matches and training sessions. The paper discusses the insufficient recovery measured related to handball performance. Because of changes in the rules of the game and strategic tendencies towards higher speed in play, the physical demands in elite handball seems to be increasing. The results of the study indicate that coaches should consider physical loading and recovery time available when distributing playing time between individual players in international tournaments.
本研究的目的是调查精英水平的手球训练和比赛后神经肌肉疲劳的程度以及从疲劳中恢复的情况。具体关注的是在3天内进行三场比赛时身体表现的变化,这模拟了国际锦标赛中的一个赛程。挪威国家女子手球队的队员在一个为期5天的训练营(7名队员)和一个为期3天的国际比赛(8名队员)期间接受了测试。在训练课程和比赛前后进行了测试。神经肌肉疲劳通过自愿等速膝关节伸展、反向移动跳跃的跳跃高度和20米短跑时间的变化来衡量。结果显示,在训练营期间,所有三项表现测试均显著下降了2%-6%,在比赛期间(短跑和跳跃测试)下降了4%-7%(P<0.05)。比赛和训练课程之间表现恢复不完全表明恢复缓慢。本文讨论了与手球表现相关的恢复不足问题。由于比赛规则的变化以及比赛中追求更高速度的战略趋势,精英手球运动对体能的要求似乎在增加。研究结果表明,教练在国际比赛中分配球员上场时间时,应考虑身体负荷和可用的恢复时间。
