Journal Article
The impact of long‐haul travel and 13 h time change on sleep and rest activity circadian rhythm in speed skaters during World Cup competitions
2025
Overview
Athletes frequently compete only a few days after long‐haul travel. Longitudinal real‐world data on athletes’ sleep and sleep–wake cycle in competitive settings remain scarce. This study assessed the impact of a long‐haul travel across ∼13 time zones on sleep patterns, rest–activity circadian rhythms (RAR), and their subsequent effects on neuromuscular function and race performance in the Canadian Short‐Track Speed Skating Team. Nineteen athletes (24 ± 4 years, 11 women) travelled from Montréal (UTC‐5) to Asia (UTC+8, UTC+9) for World Cup races between 2017 and 2019. Actigraphy data were collected before (Baseline) and during travel, during the stay in Asia (SIA), and during competition days. RAR were computed using cosinor analyses on accelerometry data with 24 h phase periods. Countermovement jump height (CMJ) was measured in a subsample (n = 10). Compared to baseline (7:08 ± 0:53), athletes obtained less sleep during travel (6:16 ± 1:27) and competition days (6:35 ± 1:10), and more during SIA (7:32 ± 0:46; time effect P < 0.0001). Sleep efficiency and CMJ were greater in SIA than baseline (P = 0.007 and P = 0.0004, respectively). During SIA, sleep time increased by 9 min per night until the fifth day (P < 0.0001), with a slight decrease in sleep efficiency (P = 0.005) and an increase in CMJ (P < 0.0001). For RAR, mean activity peaked on day 2, shifting from late evening to ∼15:00. Race performance was not different from other races of the same season (P > 0.254). Our results demonstrated that, despite the possible sleep debt from the long‐haul travel, athletes recovered within 5 days, highlighting their adaptability to manage sleep debt and jetlag without impacting competitive outcomes.
What is the central question of this study?
Which are the effects of long‐haul travel crossing ~13 time zones on sleep, RAR and performance in speed skaters travelling for competitions?
What is the main finding and its importance?
Total sleep time progressively increased for up to 5 days after landing, along with adjustments in RAR. Neuromuscular performance and competition performance remained unaltered, indicating that any potential impaitments due to travel or jet‐lag were resolved within 5 days.
