Purpose: Sufficient sleep or sleep of sufficient quality is essential for the health of children, adolescents and adults, as sleep influences almost all dimensions of life. The purpose of this study was to investigate the possible positive effects of sportsmanship on sleep quality and to assess the possible differences in sleep quality between athletes and non-athletes.

Methods: Sedentary or non-athletes subjects (n=103) and athletes (n=93) participated in this study.

Purpose: Previous studies reported a peripheral immune asymmetry and lateralization of different paired organ cancers. Because of the close relationship of immune system with body temperature, the aim of the study was to test the possible lateralization of skin temperature.

Materials And Methods: Four hundred sixty three healthy subjects (325 women, 138 men) with an average age of 23.

Purpose: The purpose of this study was to examine the efficacy of a long-term training program of 10 weeks on static and dynamic balance parameters in a young healthy population.

Methods: Participants were 35 young healthy female subjects. Balance measurements were done using the Flamingo Balance Test (FBT) for static balance and the Star Excursion Balance Test (SEBT) for dynamic balance.

The existing literature is controversial regarding the relationship between physical fitness and intraocular pressure (IOP). Therefore, the effects of acute submaximal exercise on IOP were compared in athletes and sedentary subjects. Acute exercise increased IOP in male athletes, but had no effect in sedentary men.

The long-term effects of acute submaximal exercise on intraocular pressures (IOPs) of right-and left-eyes and recovery times to basement levels of IOP in postexercise periods in sedentary and physically fit subjects were investigated. Twenty-five sedentary and 24 physically fit subjects, ranging in age 17 to 22 years, participated. Intraocular pressures were measured by a pneumotonometer.

The effects of unilateral forced nostril breathing on the intraocular pressures of right and left eyes was studied in 24 male and 26 female right-handed adults. In men, the forced breathing through both the right and left nostrils significantly decreased the intraocular pressures of both right and left eyes. For women, the forced breathing through right nostril did not affect the intraocular pressures of right and left eyes, and the forced breathing through left nostril also had no effect on the intraocular pressure of right eye, although it decreased the intraocular pressure of left eye significantly.
