Human Kinetics & Applied Health Sciences Student Works

The primary objective is to explore the physiological effects of caffeine on intra-bout exercise-induced blood pressure (BP) and heart rate (HR) deceleration resulting from repeated anaerobic exercise cycling in active university students. Use of caffeinated stimulants has increased in recent years, particularly in the exercise setting. The cardiovascular system (CS) is an essential piece of exercise physiology and is controlled by the autonomic nervous system (ANS). Caffeine has a known effect on the CS during acute exercise. What is not well solidified is the connection between caffeine and exercise-induced markers, such as heart rate recovery (HRR) and BP. Participants underwent …

The Effect Of Targeted Heart Rate Maximum Percentages On Cognitive Function In College-Aged Adults, Emily Snider, Izzy Smith

Human Kinetics & Applied Health Sciences Student Works

Previous research has displayed per the sympathetic nervous system (SNS), an increased heart rate (HR) is associated with higher cognitive function due to hormone and neurotransmitter release, specifically through the release of norepinephrine (NE) and epinephrine (EPI). The purpose of the present study is to examine if cognitive function defined by the Purdue PegBoard (PPB) is affected by targeted increases of HR maximum, as increased HR is stimulated by the SNS. METHODS: Twenty- eight healthy participants ages 20.82 ± 1.10 were recruited via email and enrolled in this study. Participants' targeted maximum HR was determined with the maximum HR equation …

The Influence Of Music Tempo On Bench Press Power Production In College-Aged Males, Samuel Linderbaum, Reese Pantila

Human Kinetics & Applied Health Sciences Student Works

Previous research suggests that music with a tempo exceeding resting heart rate may stimulate the sympathetic nervous system (SNS), releasing catecholamines (epinephrine and norepinephrine). These hormones have physiological effects such as increased heart rate and muscle strength in cardiovascular exercise. This study aims to see if the effect of music in cardiovascular exercise is also present in strength training. This will be done by examining whether pre- and intra-exercise music listening at different tempos affects power output during bench press repetitions in young adult males. It is hypothesized that music at a higher tempo will stimulate the SNS and result …

The Effect Of Vision On Lower Quarter Balance During Y-Balance Test Testing In College Students, Nathan Smith, Katelyn Mehr

Human Kinetics & Applied Health Sciences Student Works

Purpose: In order to maintain balance and stability, the body relies on the integration of information from the visual, vestibular, and proprioceptive systems. If an individual has an impairment or weakness in one or more systems, their ability to maintain balance may be impaired. Both postural stability and vision contribute to one’s ability to maintain balance in functions of everyday life. The Y-Balance Test (YBT) is a dynamic balance assessment. This study focuses on the visual system and its relation to postural balance, specifically if altered visual states affect one’s ability to maintain balance during a YBT via the use …

Acute Effects Of Mental Health On Concussion Testing, Annika Thompson, Carin Gutzwiller

Human Kinetics & Applied Health Sciences Student Works

The process of diagnosing a concussion starts long before any hit on the field. At the beginning of each season, athletes are baseline tested using the same Sports Concussion Assessment Test 5 (SCAT5) that is used on the field when injury occurs. How they perform on this baseline test plays a major role in future diagnosis. Thirty-Five male and female subjects (mean years of age 20.8 years ± 1.6) free of concussion diagnosis came in for a total of three separate appointments. At each appointment, a mental health survey, reaction time test, and the cognitive portion of the SCAT 5 …
