Abstract

Road criterium and track bicycle racing occur at high speeds, demand repeated high power outputs, last 10-90 min, and offer little chance for recovery after the event. Consecutive evenings of criterium and track racing are respectively known as speed-week or six-day events and take place in evening hours over the course of a week. Given the schedule and timing of these competitions, return to homeostasis can be compromised. No recommendations exist on how to optimize recovery for cyclists participating in these types of repeated evening competitions. Criterium and track cyclists spend considerable time, near and above the individual lactate threshold and therefore mostly utilize carbohydrate as their chief energy substrate. Henceforth, pre - and post-race nutrition and hydration is examined and recommendations are brought forward for carbohydrate, protein, and fluid intake. As evening high-intensity exercise perturbs sleep, strategies to optimize sleep are discussed and recommendations for an optimal sleep environment are given. Active recovery is examined, and the benefits of a short duration low intensity exercise reviewed. Passive recovery methods such as compression garments and cold water immersion are recommended, while evidence for massage, pneumatic compression devices, and neuromuscular electrical stimulation is still lacking. Optimizing recovery strategies will facilitate a return to the resting state following strenuous night competition.

摘要

公路自行车场地赛和计时赛的速度都很快,需要运动员反复输出高功率,比赛持续时间为 10-90 分钟,且赛后几乎没有恢复的机会。连续几天的公路自行车场地赛分别被称为速度周或六天赛,比赛时间为一周的晚上。鉴于这些比赛的日程和时间安排,运动员可能无法恢复到正常的身体状态。目前还没有针对参加这些类型的夜间重复比赛的自行车运动员如何优化恢复的建议。公路自行车场地赛运动员花费大量时间,接近甚至超过个体乳酸门槛,因此主要利用碳水化合物作为主要能量来源。因此,本文对比赛前后的营养和水分摄入进行了检查,并提出了碳水化合物、蛋白质和液体摄入的建议。由于夜间高强度运动会扰乱睡眠,因此讨论了优化睡眠的策略,并为运动员提供了最佳睡眠环境的建议。还对主动恢复进行了检查,并回顾了短时间低强度运动的好处。建议使用压缩服装和冷水浸泡等被动恢复方法,而按摩、气动加压设备和神经肌肉电刺激的证据仍然不足。优化恢复策略将有助于运动员在夜间激烈比赛后恢复到休息状态。
