The search was conducted using the key words "high-intensity intermittent training" or "high-intensity interval exercise" or "interval running" or "sprint interval training" and "endurance runners" or "long distance runners". A systematic approach was used to evaluate the 783 articles identified for initial review. Studies were included if they investigated HIIT in recreational endurance runners. The methodological quality of the studies was evaluated using the Physiotherapy Evidence Database(PEDro) scale(for intervention studies) and the modified Downs and Black Quality Index(for cross-sectional studies).Results: Twenty-three studies met the inclusionary criteria for review. The results are presented in 2 parts: cross-sectional(n = 15) and intervention studies(n = 8). In the 15 cross-sectional studies selected, endurance runners performed at least 1 HIIT protocol, and the acute impact on physiological, neuromuscular, metabolic and/or biomechanical variables was assessed. Intervention studies lasted a minimum of 4 weeks, with 10 weeks being the longest intervention period, and included 2 to 4 HIIT sessions per week. Most of these studies combined HIIT sessions with continuous run(CR) sessions; 2 studies' subjects performed HIIT exclusively.Conclusion: HIIT-based running plans(2 to 3 HIIT sessions per week, combining HIIT and CR runs) show athletic performance improvements in endurance runners by improving maximal oxygen uptake and running economy along with muscular and metabolic adaptations. To maximize the adaptations to training, both HIIT and CR must be part of training programs for endurance runners.展开更多
分析针灸对长时间运动训练的中长跑运动员(青少年运动员)半程马拉松比赛后淋巴细胞及亚群等的影响。结果显示:赛后4 h CD3+、CD4+、CD8+均比不训练时显著下降,赛后28 h基本恢复至不训练时水平,经针灸干预的CD3+、CD4+、CD8+略有增高,但...分析针灸对长时间运动训练的中长跑运动员(青少年运动员)半程马拉松比赛后淋巴细胞及亚群等的影响。结果显示:赛后4 h CD3+、CD4+、CD8+均比不训练时显著下降,赛后28 h基本恢复至不训练时水平,经针灸干预的CD3+、CD4+、CD8+略有增高,但变化无显著性差异;赛后4 h、28 h NK细胞数量呈逐渐下降,与不训练时无显著性差异,赛后28 h经针灸干预的NK细胞数量下降较未经针灸干预的少得多;赛后4 h、28 hNKT细胞数量与不训练时相比明显减少,差异显著,赛后28 h较赛后4 h少量增加,经针灸干预的增加多,有显著差异。提示:免疫系统在强烈或耐力跑后可出现短暂压抑,针灸在一定程度上可对免疫系统产生明显的调节作用。展开更多
