Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 12, 2021. Validity refers to the ability of a device to measure what it was intended to measure. Therefore, purpose of this study was to assess the validity and reliability of a novel vertical jump height tool designed by Brower Timing Systems (Salt Lake City, Ut). The Brower vertical jump system was compared to the Vertec jump tester. A convenience sample (n=67) of college students performed three maximum countermovement jumps, with the average score being recorded. Data was collected simultaneously for both devices. Results showed a strong and statistically …

Stretching After An In-Water Warm-Up Does Not Acutely Improve Sprint Freestyle Swim Performance In Diii Collegiate Swimmers, Haven L. Westra, Alexander H.K. Montoye Oct 2021

Stretching After An In-Water Warm-Up Does Not Acutely Improve Sprint Freestyle Swim Performance In Diii Collegiate Swimmers, Haven L. Westra, Alexander H.K. Montoye

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 11, 2021. Stretching, as part of a warm-up prior to competition, has been used as a method to enhance performance in swimming and other sports, but its efficacy as a potential ergogenic aid remains understudied. This study’s purpose was to determine if acute static stretching or a dynamic warm-up, following an in-water swim-specific warm-up, improved sprint freestyle swim performance in collegiate swimmers. NCAA Division III swimmers (n=15, 67% female) participated in three testing protocols. In each protocol, participants did an in-water warm up and either a dynamic warmup …

The Influence Of Overbuilt Versus Game-Permitted American Football Facemasks On Peripheral Visuomotor Ability In Ncaa Division I Football Athletes, Jai'rus L. Creamer, Rebecca R. Rogers, Courteney L. Benjamin Cscs, J. Patrick Marsh, Tyler D. Williams Cscs*D, Christopher G. Ballmann Facsm Jul 2021

The Influence Of Overbuilt Versus Game-Permitted American Football Facemasks On Peripheral Visuomotor Ability In Ncaa Division I Football Athletes, Jai'rus L. Creamer, Rebecca R. Rogers, Courteney L. Benjamin Cscs, J. Patrick Marsh, Tyler D. Williams Cscs*D, Christopher G. Ballmann Facsm

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 9, 2021. Heavier facemask reinforcement has been shown to impair reaction time. While overbuilt facemasks are illegal for gameplay at all levels of competition, empirical rationale for this has not be realized and it is unknown if overbuilt facemasks are worse for peripheral vision than permitted ones. Thus, the purpose of this study was to investigate the effects of wearing an overbuilt facemask versus game permitted facemasks on peripheral visuomotor ability in collegiate football players. Male NCAA Division I football players (n=18) completed a 60-second peripheral visuomotor test on …

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 7, 2021. The purpose of this study was to clarify the effect of the birth month on Talent Identification (TI) participation and the identification process in sports. The subjects were 4th grade elementary school children (mean age, 9±5.8 years) who participated in the Talent Identification Project. The method of identification was two-stage. In the first stage, the 30 m sprint, standing broad jump, and medicine ball front throw (1 kg) were performed, and 99 boys and 97 girls with high overall scores were selected to participate in the second …

Impact Of Nutrition-Based Interventions On Athletic Performance During Menstrual Cycle Phases: A Review, Macy M. Helm, Graham R. Mcginnis, Arpita Basu Jun 2021

Impact Of Nutrition-Based Interventions On Athletic Performance During Menstrual Cycle Phases: A Review, Macy M. Helm, Graham R. Mcginnis, Arpita Basu

Kinesiology and Nutrition Sciences Faculty Publications

Despite the steady increase in female participation in sport over the last two decades, comprehensive research on interventions attenuating the influence of female menstrual physiology on performance remains scarce. Studies involving eumenorrheic women often only test in one menstrual phase to limit sex hormone variance, which may restrict the application of these findings to the rest of the menstrual cycle. The impacts of nutrition-based interventions on athletic performance throughout the menstrual cycle have not been fully elucidated. We addressed this gap by conducting a focused critical review of clinical studies that reported athletic outcomes as well as menstrual status for …

The Effect Of An Acute Bout Of Foam Rolling On Running Economy, Lauren M. Biscardi, Brian D. Wright, Debra A. Stroiney Mar 2021

The Effect Of An Acute Bout Of Foam Rolling On Running Economy, Lauren M. Biscardi, Brian D. Wright, Debra A. Stroiney

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 4, 2021. This study examined the impact of pre-exercise foam rolling on running economy at 5 km race pace. Sixteen trained distance runners (31.5±12.2 yr; V̇O2max 53.6±11.0) volunteered for the study. Participants completed two treadmill runs at self-selected 5 km race pace; one session with the use of pre-exercise foam rolling and the other with a controlled rest period prior to the run. Running economy was improved during the session with pre-exercise foam rolling applied (t(15)=2.48, p=.026, d=.62). These findings provide evidence for the …

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 2, 2021. Metabolic equations, such as ACSM and FRIEND, are used worldwide to indirectly measure the VO2max in adults, but lack of accuracy seems to occur. 30 men of 18-34 years old performed a maximal incremental test on a treadmill during which direct VO2max measurements was taken and then have been compared to ACSM and FRIEND metabolic equations. Point of application #1: Better evaluation and exercise prescription among athletic populations. Point of application #2: Act in prevention among sedentary and symptomatic populations. Point of application …

While Topics in Exercise Science and Kinesiology (TESK) was originally designed to fill a void in publishing applied information for practitioners in physical activity and sport, the TESK editors have determined a need to update the submission categories. The categories of Process of Science and Implementation Strategies have been retained, and three new types of submissions now will be accepted: Expedited Articles, Review Articles, and Case Studies. Process of Science submissions should seek to answer the question, “What was learned from the experience of performing the investigation?”, …

Quantification And Verification Of Cardiorespiratory Fitness In Adults With Prehypertension, Dharini M. Bhammar, Lung-Chang Chien

Kinesiology and Nutrition Sciences Faculty Publications

Background: Low cardiorespiratory fitness is associated with increased risk of hypertension and atherosclerosis in adults with prehypertension. The purpose of this study was to quantify cardiorespiratory fitness and to examine the utility of supramaximal constant-load verification testing for validating maximal oxygen uptake (VO2max) attainment in adults with prehypertension. Methods: Eleven adults (four women) with prehypertension (22.5 +/- 2.9 y; body mass index (BMI): 24.6 +/- 3.2 kg center dot m(2)) underwent an incremental exercise test followed 15 min later by a verification test at 105% of maximal work rate on a cycle ergometer. Results: There was no statistical difference in …
