UNLV Theses, Dissertations, Professional Papers, and Capstones
Sport-related concussions (SRCs) play a very debilitative role in athletics with between 1.7 – 3 million SRCs occurring annually (Clay et al., 2013; Zuckerman et al., 2015). This equates to upwards of 21.5 SRCs per 1000 athletic exposures. Research pertaining to SRC has received intense focus because of the substantial financial impact on the US healthcare system as well as the negative impact that SRCs have on the quality of life of athletes. Much of the research concerning SRC has been centered around management and ensuring adequate recovery from SRC-related symptoms. The current return to play (RTP) criteria from an …

Introduction
40 million Americans run regularly.1 Contrary to many runner’s beliefs, increased strength may be beneficial while not adding body mass. An increase in strength in specific muscles may improve running gait and performance. 9,6 Strength training may also play an important role in preventing common overuse injuries in running 11,12 Depending on the style of strength training, it may also have an enhanced benefit on running economy.4,16
Participation in CrossFit is also widely popular, with an increase in participation of 923% in the past ten years.2 CrossFit is a type of strength training in which most movements performed utilize …

The purpose of this study was to determine the effects of static or dynamic stretching on hip kinematics and kinetics during intermittent sprinting. To achieve this aim, intermittent sprint athletes were asked to complete either a static or dynamic stretch, followed by a repeated-sprint protocol. Hip joint kinematics and performance measures were evaluated during the sprint, including changes that occurred in these variables over the course of the sprint protocol. In addition, hip flexion torque was measured with an isokinetic dynamometer. Ten male (age = 25±2.3 years, 175±3.2 cm, 76.2±2.7 kg) and female (age = 20±1 years, 166±1.3 cm, 60±1.1 …
