Human Movement Sciences & Special Education Faculty Publications

Although research supports the feasibility and reliability of health-related physical fitness (HRPF) tests in typically developing children and adolescents, little is known regarding the feasibility and reliability of these tests for those with hearing impairments (HI). The aim of this study was to evaluate the feasibility and reliability of a HRPF test battery for children and adolescents with HI. A test–retest design with a one-week interval was conducted with 26 participants with HI (mean age: 12.7 ± 2.8 years; 9 male). The feasibility and reliability of seven field-based HRPF tests (i.e., body mass index, grip strength, standing long jump, vital …

The Influence Of Shoe And Cleat Type On Lower Extremity Muscle Activation In Youth Baseball Pitchers, Jacob R. Gdovin, Chip Wade, Lauren A. Luginsland, Charles C. Williams, Riley Galloway, John C. Garner

Human Movement Sciences & Special Education Faculty Publications

Background: Baseball pitching is a dynamic movement where the lower extremities generate and sequentially transfer energy to the upper extremities to maximize ball velocity. The need for lower body muscular strength to produce adequate push-off and landing forces has been documented; however, the influence footwear and surface inclination has on muscle activation remains unknown.

Objectives: Determine how pitching in molded cleats and turf shoes from a pitching mound and flat ground affects stride-leg muscle activation in youth baseball pitchers while determining percent activation during each pitching phase.

Methods: Cross – sectional study analyzing mean muscle activity and percent activation of …

The Reliability Of Portable Fixed Dynamometry During Hip And Knee Strength Assessments, Roger O. Kollock Jr., James A. Onate, Bonnie Van Lunen

Rehabilitation Sciences Faculty Publications

Context: Insufficient lower extremity strength may be a risk factor for lower extremity injuries such as noncontact anterior cruciate ligament tears. Therefore, clinicians need reliable instruments to assess strength deficiencies.

Objective: To assess the intrarater, interrater, intrasession, and intersession reliability of a portable fixed dynamometer in measuring the strength of the hip and knee musculature.

Design: Crossover study.

Setting: Sports medicine research laboratory.

Patients or Other Participants: Three raters (A, B, C) participated in this 2-phase study. Raters A and B tested 11 healthy college graduate students (2 men, 9 women) in phase 1. Raters A and C tested 26 …
