Effects Of Game Pitch Count And Body Mass Index On Pitching Biomechanics In 9-To 10-Year-Old Baseball Athletes, Jim D. Darke, Eshan M. Dandekar, Arnel L. Aguinaldo, Scott J. Hazelwood, Stephen M. Klisch

Biomedical Engineering

Background: Pitching while fatigued and body composition may increase the injury risk in youth and adult pitchers. However, the relationships between game pitch count, biomechanics, and body composition have not been reported for a study group restricted to 9-to 10-year-old athletes.

Hypothesis: During a simulated game with 9-to 10-year-old athletes, (1) participants will experience biomechanical signs of fatigue, and (2) shoulder and elbow kinetics will correlate with body mass index (BMI).

Study Design: Descriptive laboratory study. Methods: Thirteen 9-to 10-year-old youth baseball players pitched a simulated game (75 pitches). Range of motion and muscular output tests were conducted before and …

Preparation For The Study Of Gene Expression Aboard The International Space Station, Amber Paturzo

STAR Program Research Presentations

WetLab-2 performs quantitative polymerase chain reaction (qPCR) aboard the micro-gravity environment of the International Space Station in order to research how the stress of micro-gravity affects an organism’s RNA production and gene expression. This on-station qPCR allows researchers to gather information earlier and thereby allow them to modify experiments in a matter of hours rather than wait until the next flight opportunity. After a successful validation flight on SpaceX-8 and follow-up investigation on SpaceX-9, system components must now be adjusted for a new type of biological sample. Specifically, the WetLab-2 facility includes a commercial qPCR instrument (RNA SmartCycler), a sample …
