The physiological responses to skating and the incidence of injuries were recorded in young, Danish elite figure skaters (n = 8) over a 1-year period. The skaters' maximum oxygen uptake (VO2 max) ranged from 54.7 to 68.8 ml kg-1 min-1, and work intensity during simulated competitive figure skating corresponded to 89% VO2 max. Before the onset of competitive skating, but after a warm-up, blood lactate (BLa) concentration was measured as 2.0 +/- 0.05 mM (means +/- S.E.). After a 4-min run, BLa increased to 8.0 +/- 0.6 mM. The subjects' resting heart rates were measured each morning over a 1-year period and corresponded to 53 +/- 2 and 58 +/- 3 beats min-1 for the males and females respectively, with no systematic season-related variations. The skaters trained for 15-41 h per week, 60-95 min of this time being spent on warm-up activities. The injury incidence rate during competitive skating was recorded as 1.4 injuries per 1000 h of training, 56% of these being acute and 44% chronic injuries. Of those injuries registered, 83% were recalled by the skaters when a retrospective questionnaire was given to them at the end of the observation period. This study indicates that ice figure skating is associated with high aerobic power. Furthermore, Danish skaters spend large amounts of time on training, including warm-up and stretching. Despite the amount of training and the intensity of ice-skating programmes, injury rates are low compared with other sporting events.
在为期1年的时间里,对8名年轻的丹麦优秀花样滑冰运动员的滑冰生理反应和受伤发生率进行了记录。这些滑冰运动员的最大摄氧量(VO2 max)在54.7至68.8毫升/千克·分钟之间,模拟花样滑冰比赛期间的工作强度相当于VO2 max的89%。在正式比赛开始前,但经过热身之后,测得血乳酸(BLa)浓度为2.0±0.05毫摩尔/升(平均值±标准误)。经过4分钟的滑行后,BLa升至8.0±0.6毫摩尔/升。在1年的时间里,每天早晨测量受试者的静息心率,男性和女性的静息心率分别为53±2次/分钟和58±3次/分钟,没有与季节相关的系统性变化。这些滑冰运动员每周训练15至41小时,其中60至95分钟用于热身活动。花样滑冰比赛期间的受伤发生率记录为每1000小时训练1.4次受伤,其中56%为急性损伤,44%为慢性损伤。在记录的那些损伤中,当在观察期结束时向滑冰运动员发放回顾性调查问卷时,83%的损伤被他们回忆起来。这项研究表明花样滑冰与高有氧能力有关。此外,丹麦滑冰运动员在训练上花费大量时间,包括热身和拉伸。尽管训练量和滑冰项目强度较大,但与其他体育赛事相比,受伤率较低。
