Aim. The aim of the ­present ­study was to inves­ti­gate the ­effect of ­sleep dep­ri­va­tion on ­shuttle run ­score (cor­re­sponding to an esti­mated V.#O2 ­peak) in ­middle-­aged ama­teur ath­letes.
­Methods. ­Twenty-two ath­letes, ­training 9.2 ­hours a ­week (±4), per­formed a ­Léger and ­Gadoury ­shuttle ­test ­daily in a 4-day ­series ­that ­included a pre-­test in day 0, 28 ­hours ­without ­sleep ­before ­test 1 (and 10 ­another ­hours ­after the ­test and ­before bed­time for a ­sleep dep­ri­va­tion of 38 ­hours), and ­then 10 ­hours of ­sleep ­before ­each of ­days 2 and 3.
­Results. ­Shuttle run ­score ­showed no sig­nif­i­cant dif­fer­ence ­over the 4 ­days; how­ever, the ­change in ­shuttle run ­score on day 2 was sig­nif­i­cantly cor­re­lated ­with the ­initial ­score.
Con­clu­sion. ­This ­result sug­gests ­that ­effect of ­sleep dep­ri­va­tion on ­shuttle run ­score is depen­dent on ­initial ­score and may ­encourage ­high ­level ­aerobic ath­letes to ­avoid ­sleep dep­ri­va­tion 2 ­days ­before a com­pe­ti­tion.
