Abstract Purpose To explore the prevalence of obstructive sleep apnea (OSA) within a professional rugby league team and determine associations of OSA with ethnicity, positional group, and physical characteristics. Methods 22 professional rugby league athletes underwent one night of home-based polysomnography with apnea-hypopnea index (AHI), rapid eye movement (REM)AHI, non-REMAHI and supineAHI determined to indicate OSA. Linear models were used to assess if playing position (back or forward) or ...

Purpose : External counterpulsation (ECP) has previously been used to treat cardiac patients via compression of the lower extremities during diastole to increase venous return and coronary perfusion. However, the effects of ECP on exercise performance and markers of recovery in elite athletes is largely unknown. Methods : On two separate occasions, 48 h apart, seven elite National Rugby League players performed an identical 60 min field-based conditioning session followed by a 30 min period of e...

Abstract Objective To examine the usefulness of sleep hygiene education on the sleep of professional rugby league athletes during a 10-week period of the competitive season. Design Case study. Participants Twenty-four professional rugby league athletes. Measurements Initially, participants were monitored for a 2-week period using wrist activity monitors allowing baseline estimation of sleep. Following this, 12 athletes attended two 30-minute sleep hygiene education seminars delivered over succes...

Purpose: The aim of the present study was to examine the reliability and usefulness of a proposed 4-min individualised submaximal shuttle run test (SSRIndiv) in elite rugby league players. Materials and methods: Twenty-two elite rugby league players competing in the National Rugby League competition (23.2 ± 3.4 years, 186.8 ± 5.4 cm, 100.2 ± 8.5 kg) performed the SSRIndiv twice, seven days apart (test–retest design). The SSRIndiv was prescribed as 75% of the average speed during a 1500-m time tr...

ABSTRACTThis study examined agreement between self-perceived sleep and sleep estimated via activity monitors in professional rugby league athletes. 63 athletes, from three separate teams wore actigraphy monitors for 10.3 ± 3.9 days. During the monitoring period, ratings of perceived sleep quality (on a 1–5 and 1–10 Likert scale), and an estimate of sleep duration were recorded daily. Agreement between sleep estimated via activity monitors and self-perceived sleep was examined using mean bias, Pe...

Sleep is a re-occurring behavioral state of reduced movement and responsiveness. In its simplest form, sleep allows rest from the preceding period of wakefulness. Adequate sleep is distinguished by ample duration, high efficiency, and suitable routine, while following adequate sleep one should feel refreshed and sustain alertness during wake periods. For adults, seven to nine hours of sleep per night is recommended, with less sleep than this considered sub optimal, and likely to compromise healt...

This study examined the sleep intra-individual variability (IIV) of rugby league athletes across senior and junior levels during one week of the competitive season. Forty-five rugby league athletes across elite senior, sub-elite senior and elite junior levels each wore actigraphy monitors for seven days during the competitive season, and completed a subjective sleep diary each morning upon waking. Linear mixed models were used to assess differences in sleep measures between playing levels. Intra...
