Abstract
The purpose of this study was to evaluate the sleep and physiological conditions of athletes using a noncontact sheet-type sensor (Nemuri Monitor; Aisin Seiki Co., Ltd.). Using the sheet-type sensor, sleep parameters, heart rate (HR), and respiratory rate (RR) were monitored in 7 female intercollege level middle-distance runners, who participated in a 7-night hypoxic training camp study, in which the first night was normoxic and the next 6 nights were hypoxic. Blood oxygen saturation (SpO2) was simultaneously recorded with a pulse oximeter (Pulsox-300i; Konica Minolta Optics, Inc.). Because this was a part of a hypoxic training camp study, they underwent strenuous training during the daytime. On hypoxic night 1, acute hypoxia-induced changes, such as increases in HR, RR, and body motion during sleep, and decreases in SpO2 were observed. Until hypoxic night 6, SpO2 did not change, whereas the other parameters improved toward values that would be obtained under a normoxic night. Thus, the sheet-type sensor could be used to evaluate the sleep and physiological conditions of athletes undergoing "living-high" regimens.
