Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 11, 2022. Bioelectrical impedance analysis (BIA) methods estimate health parameters such as phase angle (PhA) and body fat percentage (%BF) from various positional and electrode configurations. PhA and %BF are known biological markers of cellular and physical health, respectively, and can be used to predict various health-related conditions and therefore require accurate assessment. The purpose of this study was to evaluate the effect of body position during BIA by investigating the difference and agreement between PhA and %BF using RJL (supine) and InBody (vertical) analyzers. Thirty-eight young adults (23.4 …

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 9, 2022. The purpose of this study was to measure lower extremity muscle activity during recumbent stepping under varied conditions. We hypothesized that different stepping conditions would lead to significant changes in muscle activity. Fifteen healthy adults (4 men, 11 women; mean age 24.5 ± 7.7 yrs) provided informed consent to participate. During a single session, electromyography (EMG) was used to measure muscle activity of the tibialis anterior (TA), medial gastroc (MG), rectus femoris (RF), and biceps femoris (BF) muscles as a percent of maximal voluntary contraction (%MVC) during …

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 8, 2022. Extremely high heat stress environmental conditions in sub-Saharan Africa influences sports performance. The aim of this study was to assess physical changes and physiological responses associated with wearing judogi during 8 weeks training session in a hot environment. In this quasi-experimental study, trained male judokas (20.06 ± 1.24 years old), were assessed before and after a training session, while either wearing a judogi (experimental group n = 12) or cotton tee shorts (control group n = 12). All athletes completed testing and were evaluated for anthropometric, physiological …

The Effects Of Ladder Training On Sprint And Change Of Direction Performance, Trevor Short, Tina Manos, Justus Ortega, Andrew Peterson, Young Sub Kwon

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 7, 2022. Ladder training is a form of multidirectional lower limb plyometric training utilized by coaches and athletes in a variety of sports. The purpose of this study was to examine the effects of ladder training (LT) on sprint (20-m) and change of direction (COD) (L-drill) kinematics. Fourteen NCAA D-2 Basketball players were matched on baseline performance rankings and randomly assigned to a LT (n = 7) or conventional training (CT) (n = 7) group. The LT group performed all the CT exercises with the addition of …

The Utilization Of Crispr/Cas9 In Monogenic Disorders Authors, Shauna M. Mellor Aug 2022

The Utilization Of Crispr/Cas9 In Monogenic Disorders Authors, Shauna M. Mellor

Spectra Undergraduate Research Journal

This paper is a literature review of various scientific research papers, exploring the recent scientific advancement in the field of genetic engineering. The research presented is a foundational tool, building awareness on the implications of CRISPR/ Cas9 technology. CRISPR/ Cas9 was first discovered through the study of bacterial immune systems, fighting against viral infections. Manipulation of the Cas9 protein would eventually lead to target specific, gene-altering medicines for human organisms. CRISPR/ Cas 9 technology has begun to show promise as an effective treatment for certain monogenic disorders. Despite this, time is required before its efficacy as a proven genetic treatment …

Body Composition Of Utah Highway Patrol Officers: No Difference Between Air Displacement Plethysmography And Alternative Tools For Measurement And Prediction., Peter Macgregor, Justin R. Brown, Jacqueline Spoon, L Nathan Thomas

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 6, 2022. Different techniques exist for examining body composition. The purpose of this study was to examine differences in body fat percentage as measured by air displacement plethysmography (ADP), body adiposity index (BAI), bioelectrical impedance (BIA), a body mass index conversion equation (BMID), and skinfolds (SKF). Twenty-one male Utah Highway Patrol Officers participated in this study (age 35.19 ± 10.32 years, 1.79 ± 0.09 m tall, 92.20 ± 14.56 kg in weight, and 105.52 ± 10.01 cm hip circumference). All measurements were taken during a single visit …

Is Body Composition Or Body Mass Index Associated With The Step Count Accuracy Of A Wearable Technology Device?, Jeffrey Montes, Richard D. Tandy, John C. Young, Szu-Ping Lee, James W. Navalta Jun 2022

Is Body Composition Or Body Mass Index Associated With The Step Count Accuracy Of A Wearable Technology Device?, Jeffrey Montes, Richard D. Tandy, John C. Young, Szu-Ping Lee, James W. Navalta

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 5, 2022. A simple way to gauge daily physical activity levels is to use a wearable technology device to count the number of steps taken during the day. However, it is unknown whether these devices return accurate step counts for persons with different body fat percentages or body mass index scores. The purpose was to determine if there is a correlation between either body fat percentages and/or body mass index values and the percent error calculated between a manual step count and values recorded by a wearable technology device. …

Velocity-Based Training: Current Concepts And Future Directions, Toby Brooks, Wil Fleming, Larry Munger, Katie Munger

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology 3(1): Article 1, 2022. Velocity-based training (VBT) is a current approach to resistance training that relies on measured bar, implement, and/or athlete speed to formulate and adjust training for both long-term programming and daily training sessions. Relying on a number of available tools of varying levels of accuracy, VBT can help the strength and conditioning specialist and/or the rehabilitation professional to not only better predict strength and power over time, but also to adjust training loads in order to maximize training response in a given session. While the appeal and price points of available …
