Physical Therapy Faculty Articles and Research

Objectives

To investigate the changes in lumbar kinematic and paraspinal muscle activation before, during, and after a 4-week minimalist running training.

Design

Prospective cohort study.

Setting

University research laboratory.

Participants

Seventeen habitually shod recreational runners who run 10–50 km per week.

Main outcome measures

During stance phases of running, sagittal lumbar kinematics was recorded using an electrogoniometer, and activities of the lumbar paraspinal muscles were assessed by electromyography. Runners were asked to run at a prescribed speed (3.1 m/s) and a self-selected speed.

Results

For the 3.1 m/s running speed, significant differences were found in the calculated mean lumbar posture …

Influence Of Posture-Cuing Shirt On Tennis Serve Kinematics In Division Iii Tennis Players, Joseph Zappala, Caroline Orrego, Emily Boe, Heather Fechner, Derek Salminen, Daniel Cipriani

Objective: Injuries to the shoulder complex are common in overhead athletes, often related to kinematics of the shoulder complex. This study evaluated the influence of a posture-cuing shirt on internal rotation velocity of the shoulder during a tennis swing and to determine this influence on shoulder external rotation position. Methods: Nine healthy competitive college tennis players from a Division III college participated in this study. High speed motion capture allowed for 3-D analysis of shoulder kinematics during a tennis serve. Two conditions were evaluated while the athletes performed a high velocity tennis serve: standard tennis shirt and a …
