in scrum characteristics, specifically timing and stability, in international rugby union. It is hypothesized that changes would result in longer contact durations and a reduction in the number of reset or collapsed scrums, due to a more controlled engagement. Methods Study Design and Sample The Six

Sleep is essential for optimal health and restorative functioning. 1 , 2 The timing of an individual’s preferred bedtime and wake time affects their circadian rhythm (ie, body temperature, hormones), which can affect sleep duration and quality, and potentially athletic performance during the

-reported sleep duration as a predictor of outcome measures due to its lack of validity compared with actigraphy ( 11 , 18 ), instead using a measure of sleep quality within individuals’ well-being questionnaires ( 1 , 10 , 37 , 47 ). However, the validity of subjective sleep quality measures has also been

in patients with chronic LE. 9 A way to study the involvement of the radial nerve in LE patients could be by the use of a traditional test of nerve excitability, such as the strength–duration curves (S-D curves). 14 – 22 A S-D curve is based on the relationship between the intensity of an electric

Two hypotheses were formulated: (1) that a single long-duration exposure
