 note = {This case study examined the sleep practices of a Japanese college swimming team. For one week, we collected data on the sleep and wake-up times of 16 swimming team members attending a sports college in Japan. The results showed that the participants’ wake-up times varied during weekdays (F [4,63] = 5.326, p < 0.001). Their mean bedtime was significantly earlier on weekdays than on weekends (24.62 ± 1.50 vs. 25.83 ± 1.98; t [7] = -2.78, p = 0.027). Similarly, their mean wake-up time on weekdays was significantly earlier than that on weekends (7.68 ± 1.63 vs. 9.32 ± 2.83; t [7] = -2.94, p = 0.022). In conclusion, the studied college athletes had a nighttime sleeping habit, and their bedtimes did not change even when they had morning practices on weekdays. Furthermore, they slept and woke up later on weekends, which indicates that they did not have a regular sleep rhythm. The need for sleep education for college athletes was reaffirmed.},
