Collegiate Student-Athletes' Use and Knowledge of Third-Party-Tested Nutritional Supplements: An Exploratory Study.

Context: Nutritional supplement use in athletes is common, accompanied by potential doping risk.

Objective: To determine athletes' nutritional supplement and third-party-tested (TPT) supplement use, supplement knowledge, and factors influencing their behavior.

Design: Cross-sectional study.

Predisposing Risk Factors for Stress Fractures in Collegiate Cross-Country Runners.

Giffin, KL, Knight, KB, Bass, MA, and Valliant, MW. Predisposing risk factors and stress fractures in collegiate cross-country runners. J Strength Cond Res 35(1): 227-232, 2021-The purpose of this study was to explore factors associated with increased stress fractures in collegiate cross-country runners.

Association between athletic participation and the risk of eating disorder and body dissatisfaction in college students.

Objective: Given that females exhibit a greater prevalence of eating disorders, there is of yet no conclusive evidence whether participation in college athletics exacerbates eating disorders or body shape dissatisfaction. This study assessed how gender and participation in collegiate athletics are associated with increased risk for disordered eating attitudes and body shape concerns in college students.

Methods: This study used a cross-sectional research design.

A Prospective Study Comparing Distance-based vs. Time-based Exercise Prescriptions of Walking and Running in Previously Sedentary Overweight Adults.

Prior work has reported that the declines observed in body mass index (BMI) and circumference measurements in their cross-sectional data were twice as large when calculated from distance energy expenditure estimations compared to energy expenditure estimations based on time and intensity. The primary purpose of this study was to compare walking/running for distance to walking/running for time as part of an exercise intervention. This study followed a between-subjects, repeated measures design.

Effects of Jaw Clenching and Jaw Alignment Mouthpiece Use on Force Production During Vertical Jump and Isometric Clean Pull.

Allen, CR, Fu, Y-C, Cazas-Moreno, V, Valliant, MW, Gdovin, JR, Williams, CC, and Garner, JC. Effects of jaw clenching and jaw alignment mouthpiece use on force production during vertical jump and isometric clean pull. J Strength Cond Res 32(1): 237-243, 2018-This study examined the effects of jaw clenching, a self-adapted, jaw-repositioning mouthpiece on force production during maximum countermovement vertical jump and maximum isometric midthigh clean pull assessments in an attempt to determine any ergogenic effect attributable to clenching, jaw-repositioning mouthpiece use, or the combination of both.

Nutrition education by a registered dietitian improves dietary intake and nutrition knowledge of a NCAA female volleyball team.

Eleven female participants from a NCAA Division I volleyball team were evaluated for adequate energy and macronutrient intake during two off-seasons. Total energy and macronutrient intake were assessed by food records and results were compared against estimated needs using the Nelson equation. Dietary intervention was employed regarding the individual dietary needs of each athlete as well as a pre- and post-sports nutrition knowledge survey.

Higher amounts of body fat are associated with inadequate intakes of calcium and vitamin D in African American women.

Calcium and vitamin D are associated with obesity. We hypothesized that African American women with higher calcium and vitamin D intakes would have lower body fat compared with women with lower calcium and vitamin D intakes. This cross-sectional study included 100 premenopausal African American women aged 18 to 40 years with a spectrum of body mass indices (17.
