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) …

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, …
