Purpose: The purpose of this study was to examine the effects of static and proprioceptive neuromuscular facilitation (PNF) stretching of shoulder internal rotators on throwing velocity as compared to a typical dynamic warm-up.
Subjects: 27 male untrained throwers (mean age = 25.1 years old, SD =2.4) with basic knowledge of throwing mechanics.
Methods:The study was conducted over a series of three sessions with at least one week between each session. During each session, subjects warmed-up, threw 10 pitches, were randomly assigned to one of three separate stretching protocols, and then threw 10 more pitches.The three protocols were static stretching, …

Purpose: Barefoot running (BF) is popular in the running community. Biomechanical changes occur with BF, especially when initial contact changes from rearfoot strike (RFS) to forefoot strike (FFS). In addition, changes in lumbar spine range of motion (ROM), particularly involving lumbar lordosis, have been associated with increased low back pain (LBP). However it is not known how changing from RFS to FFS affects lumbar lordosis or LBP. Thus, the purpose of this study was to determine if a change from RFS to FFS would change lumbar lordosis, and/or decrease shock attenuation, and/or change comfort levels in healthy recreational/experienced runners.

Background: The purpose of this systematic review was to examine effectiveness of land-based exercise interventions for improving quality of life (QOL) of individuals with symptomatic knee osteoarthritis.
Methods: A systematic search included PubMed, CINAHL, Scopus, Academic Search Premier, and the Cochrane Database of Systematic Reviews. Inclusion criteria included land-based exercise interventions aimed to improve lower extremity strength and QOL, published since 2000. Exclusion criteria included OA of joints other than the knee, and aquatic-based and surgical interventions. Studies were evaluated using a modified version of the American Academy of Cerebral Palsy and Developmental Medicine (AACPDM) methodology score.
Results: Level of …

Objectives: The purpose of this study was to establish reliability and responsiveness of the active dynamic visual acuity test (DVAT) at speeds of 150 to 200 degrees per second (deg/sec) and the gaze stabilization test (GST) in high school and college football players.
Design: Reliability design
Setting, Participants, Main Outcome Measures: A total of 50 high school and college football athletes completed vestibulo-ocular reflex testing using the DVAT and GST in the yaw (horizontal) and pitch (vertical) planes on two separate occasions within 14 days.
Results: Test-retest reliability for the DVAT was good in yaw, Intraclass Correlation Coefficient (ICC) (3,3) …
