Non-contact sheet type movement sensor for sleep monitoring was applied to monitor collegiate long-distance runners' sleep. Recordings were made during summer camp and during autumn semester，about two weeks each throughout 24 hours. The percentage of missing data was 11.6% out of total recording time of 13 subjects. Sleep lengths during summer camp season were significantly longer. Night sleep phase during semester varied whereas those during summer camp were very fixed． Compared to wrist actigram，this sheet type sleep monitor gives less interference for athletes schedule and suitable for monitoring their sleep specially for long-term monitoring.
