Title: | The Travel Demands of an Elite Rugby Sevens Team: Effects on Objective and Subjective Sleep Parameters | Contributor(s): | Leduc, Cedric (author); Robineau, Julien (author); Tee, Jason C (author); Cheradame, Jeremy (author); Jones, Ben (author); Piscione, Julien (author); Lacome, Mathieu (author) | Publication Date: | 2021-05 | Early Online Version: | 2021-02-04 | DOI: | 10.1123/ijspp.2020-0243 | Handle Link: | https://hdl.handle.net/1959.11/44849 | Abstract: | Purpose: To explore the effects of travel related to international rugby sevens competition on sleep patterns. Methods: A total of 17 international male rugby sevens players participated in this study. Actigraphic and subjective sleep assessments were performed daily during 2 separate Sevens World Series competition legs (Oceania and America). The duration of each competition leg was subdivided into key periods (pretour, precompetition, tournament 1, relocation, tournament 2, and posttour) lasting 2 to 7 nights. Linear mixed models in combination with magnitude-based decisions were used to assess (1) the difference between preseason and key periods and (2) the effect of travel direction (eastward or westward). Results: Shorter total sleep time (hours:minutes) was observed during tournament 2 (mean [SD], 06:16 [01:08]), relocation (06:09 [01:09]), and the pretour week (06:34 [01:24]) compared with the preseason (06:52 [01:00]). Worse sleep quality (arbitrary units) was observed during tournament 1 (6.1 [2.0]) and 2 (5.7 [1.2]), as well as during the relocation week (6.3 [1.5]) than during the preseason (6.5 [1.8]). When traveling eastward compared with westward, earlier fall-asleep time was observed during tournament 1 (ES - 0.57; 90% CI, -1.12 to -0.01), the relocation week (-0.70 [-1.11 to -0.28]), and the posttour (-0.57 [-0.95 to -0.18]). However, possibly trivial and unclear differences were observed during the precompetition week (0.15 [-0.15 to 0.45]) and tournament 2 (0.81 [-0.29 to 1.91]). Conclusion: The sleep patterns of elite rugby sevens players are robust to the effects of long-haul travel and jet lag. However, the staff should consider promoting sleep during the tournament and relocation week. | Publication Type: | Journal Article | Source of Publication: | International Journal of Sports Physiology and Performance, 16(5), p. 688-694 | Publisher: | Human Kinetics, Inc | Place of Publication: | United States of America | ISSN: | 1555-0273 1555-0265 |
