标题：Internal training load and performance indices of cerebral palsy football players and effects of one week with and without training on heart rate variability
摘要：The aim of this study was to describe Yo-Yo Intermittent Recovery level 1 (IR1) performance and internal training load (ITL) of cerebral palsy football (CP-Football) players from a national team during one week of training and analyze the effects of this week on athletes taking part or not in training with regards to HRV indices. The sample consisted of 10 CP-Football players who were submitted to a regular one week of training,and one injured CP-Football player who had to withdraw from training. ITL was monitored using the session rating of perceived exertion. The heart rate variability (HRV) of all players was verified on the first (pre) and sixth (post) days. The Yo-Yo IR1 was performed three weeks before the monitored week. The team covered 516.0m (± 201.7) in the Yo-Yo IR1,while the injured player covered 880m. An ITL of ~600 A.U. was performed in the training week. There was a likely decrease in SDNN,rMSSD,LF,and HF during the monitored training week,and the LF/HF presented unclear changes. The HRV variables increased in the injured player after the week without training. The National team CP-football players covered less distance in the Yo-Yo IR1 test than football players without physical disabilities. The ITL observed in one week of training was capable of disturbing HRV indices. This finding was reinforced by improved HRV indices presented by the injured player.
