High-Intensity Interval Exercise Performance and Short-Term Metabolic Responses to Overnight-Fasted Acute-Partial Sleep Deprivation

Abstract

People practicing high-intensity interval exercise (HIIE) fasted during the morning hours under a lack of sleep. Such a habit may jeopardize the health benefits related to HIIE and adequate sleep. Fifteen habitually good sleeper males (age 31.1 ± 5.3 SD year) completed on a treadmill two isocaloric (500 kcal) HIIE sessions (3:2 min work:rest) averaged at 70% VO2reserve after 9–9.5 h of reference sleep exercise (RSE) and after 3–3.5 h of acute-partial sleep deprivation exercise (SSE). Diet and sleep patterns were controlled both 1 week prior and 2 days leading up to RSE and SSE. HIIE related performance and substrate utilization data were obtained from the continuous analysis of respiratory gases. Data were analyzed using repeated measures ANOVA with the baseline maximum oxygen uptake (VO2max) and body fat percentage (BF%) as covariates at p < 0.05. No difference was observed in VO2max, time to complete the HIIE, VE, RER, CHO%, and FAT% utilization during the experimental conditions. Whether attaining an adequate amount of sleep or not, the fasted HIIE performance and metabolism were not affected. We propose to practice the fasted HIIE under adequate sleep to receive the pleiotropic beneficial effects of sleep to the human body.

Effects of Acute-Partial Sleep Deprivation on High-Intensity Exercise Performance and Cardiac Autonomic Activity in Healthy Adolescents

“…There was no difference in the intermittent aerobic performance test scores for Taekwondo players the next morning after acute-partial sleep deprivation (≤3 h) compared with the control sleep group (≥7.5 h) [56]. High-intensity interval exercise performance was not impaired by partial sleep deprivation (3-3.5 h) compared to those with enough sleep (9-9.5 h) [57]. In summary, influenced by the exercise protocols, it is possible that shorter exercise duration and lower intensity under controlled conditions was perceived as more easeful, arousing less fatigue and permitting subjects to perform the same protocol if in the SD group.…”

Effects of Acute Partial Sleep Deprivation and High-Intensity Interval Exercise on Postprandial Network Interactions

“…As stated, this paper is revisiting data collected as part of a bigger project that involved parameters related to sleep, exercise, and cardiovascular function and outcomes of these investigations presented in detail elsewhere (Papadakis et al, 2020;Papadakis et al, 2021a;Papadakis et al, 2021b). Briefly, a within-subject randomized crossover experimental design with three 3) experimental conditions (i.e., a reference sleep-no exercise "control condition" (RS) in which a standardized test meal was ingested in the morning after 9-9.5 h of time-in-bed in which at least 8 h of sleep was attained; a "reference sleep and high-intensity interval exercise condition" (RSX), similar to RS condition in terms of the meal and the obtained sleep time with the exception of a high-intensity interval exercise with 3:2 intervals at 90 and 40% of VO 2 reserve that averaged 70% of VO 2 reserve and expended 500 kcals of energy, and; a "short and disrupted sleep and high-intensity interval exercise-acute partial sleep deprivation condition" (SSX), similar to RSX in terms of the meal and the performed exercise with the exception of the sleep time that was regulated to 3-3.5 h of time-in-bed limited to no more than 3.5 h of sleep) was employed to answer the research questions as depicted earlier (Figure 1).…”

“…As noted earlier, the dataset for this manuscript was based on previous work and all the related statistical analyses are described in detail elsewhere (Papadakis et al, 2020;Papadakis et al, 2021a;Papadakis et al, 2021b). We used LDL cholesterol, a marker of cardiovascular risk, due its important clinical significance in cardiovascular disease (Cromwell et al, 2007;Trejo-Gutierrez and Fletcher, 2007), exercise (Durstine et al, 2002), and HRV interactions (Kupari et al, 1993;Christensen et al, 1999;Thayer et al, 2010;Chung et al, 2020;Vijayabaskaran et al, 2022).…”

“…Research questions related to the immediate HRV responses after acute HIIE following reference sleep and APSD are still under investigation. Previous work from our lab has examined such research questions (Papadakis et al, 2020;Papadakis et al, 2021a;Papadakis et al, 2021b) under the traditional Exercise Physiology approach, which focuses on a single physiological system by reducing complex multicomponent systems on their respective parts (Machamer et al, 2000;Bechtel and Richardson, 2010;Balague et al, 2020). We reported that the expected HRV disturbance as a response to an acute HIIE was not influenced by APSD (Papadakis et al, 2021a), HIIE after APSD was still cardioprotective for the postprandial endothelial function (Papadakis et al, 2020), and lastly that fasted HIIE and performance were not affected by sleep conditions (Papadakis et al, 2021b).…”

“…Therefore, this paper attempts to revisit our previous work (Papadakis et al, 2020;Papadakis et al, 2021a;Papadakis et al, 2021b), through the prism of Network Physiology of Exercise (NPE) (Balague et al, 2020), a new branch of the interdisciplinary field of Network Physiology (Ivanov et al, 2016;Ivanov, 2021;Ivanov et al, 2021). NPE addresses the fundamental question of how physiological systems coordinate and synchronize their dynamics as a network to optimize organism function, and how these network interactions change in response to exercise and training.…”
