To improve maximal endurance or strength performance, an optimal physiological training load is required. Inadequate recovery time facilitate to fatigue and underperformance. Post-exercise heart rate variability (HRV) has been shown to be a valid method to evaluate the training load (Kaikkonen ym. 2010; Kaikkonen ym. 2012). The purpose of this study was to determine whether the HRV, selective physiological indicators and sleep could assess cumulative metabolic and neuromuscular fatigue induced by the short-term high-intensity training blocks. We hypothesized that following high-intensity training block HRV remains longer declined level compared to strength training blocks (Buccheit ym. 2004; Chen ym. 2011; Hynynen ym. 2010). Also we assumed total sleep time increases, sleep efficiency is higher, wake time is less after onset, in REM sleep increases and slow wave sleep (SWS) increases (Driver & Taylor 2010; Myllym\u00e4ki ym. 2011) following high-intensity endurance training block, and sleep parameters remains constant over the strength training blocks (K\u00f6llning ym. 2015). \nMethods. The subjects were endurance and strength trained men (n=18); 29\u00b16 yrs; 180 \u00b1 6 cm; 79 \u00b1 12 kg; VO2max 54 \u00b1 6 ml/kg/min. Study included three different training blocks; high-intensity endurance, maximal strength and hypertrophy strength. Three consecutive high-intensity late-night exercise sessions followed by four days of recovery period before the new training block. WHO\u2019s cycling fitness test, countermovement jump test, saliva cortisol concentrations, subjective perceived stress and subjective quality of sleep were measured at mornings before the training blocks and following mornings after the training sessions. Emfit sleep monitor measured HRV and sleep quality every night throughout the research period. The variance analysis of repeated measurements and non-parametric Friedman and Wilcoxon tests were used in the statistical analysis of the results. The correlations between the variables were analysed using Spearman correlation tests.The limit of the statistical significance was p < 0.05. \nResults. Although subjects experienced the exercise sessions physically very demanding, no statistically significant differences were found between the single exercise sessions or between the training blocks in performance measurements (WHO\u2019s cycling test and a countermovement jump test), cortisol levels, subjective stress and HRV. Statistically significant differences were not observed in sleep or relative portion of sleep phases during any training blocks. Some trends were observed as RMSSD (Root Mean Square of the Successive R\u2013R Differences) sleep score and sleep duration were systematically lower after training blocks than recovery periods. \nDiscussion and conclusion. Based on this study, short-term high-intensity training blocks are well tolerated in physically active men as they were not associated to significant physiological fatigue or associated with the disturbances in sleep quality or HRV. It can be concluded that metabolic and neuromuscular fatigue are associated to heart rate variability so that if there were not metabolic or neuromuscular fatigue, there were either changes in autonomic nervous system. Furthermore, in this study found cortisol did not changes after single or three consecutive exercise sessions. Stability of the cortisol is related to heart rate variability changes (no changes). Additionally, the results of present study suggest that quality of the sleep or relative portion of sleep phases during any training blocks. Probably greater training loads and/or longer training period are required in order to induce physiological changes in autonomic nervous system, cortisol concentration, physical performance or sleep phases.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2019-06-28T06:04:51Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-06-28T06:04:51Z (GMT).
