Investigation Of Algorithms To Assess Validity Of Wearable Technology During Field Testing, Brenna Barrios

UNLV Theses, Dissertations, Professional Papers, and Capstones

Wearable technology is an emerging fitness trend where the technology which supports it lacks validity verification. Furthermore, heart rate validity of these devices vary greatly when observed in laboratory settings vs. field testing. Secondarily, Consumer Technology Association guidelines require a minimum five minute trial for wearable testing. This study examined heart rate data of previously tested wearable devices (Garmin Fenix 5, Jabra Elite Sport, Motiv Ring, Scosche Rhythm+) in an outdoor setting to further understand their performance, and to examine the relationship of the five minute regulation. Two separate algorithms were applied to the original data set, the first shortened …

College Student Depression: An Examination Of Cardiorespiratory Fitness, Gender And Sexual Orientation Diversity, And Help-Seeking Willingness, Sharon Jalene

UNLV Theses, Dissertations, Professional Papers, and Capstones

Depression is a serious illness characterized by persistent low mood, reduced cognitive capacity, and fatigue. Although treatable, depression is the leading cause of disability and ill-health worldwide and a significant contributor to suicide, the second leading cause of death for young Americans. In any given two-week period, 8.1% of adults in the United States had moderate to severe depression (2013-2016). The rate of depression for females was twice that of males and compared to the majority, sexual and gender minorities (SGM) were at a threefold risk. Furthermore, evidence suggests that depression incidence is three times higher in college students than …

Vitamin D Status And Bone Mineral Density In Triathletes, Michelle Konstantarakis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: The purposes of this study were first to assess the vitamin D status and bone mineral density (BMD) in male and triathletes (N=15), female triathletes (N=13), and non-athletes (N=14), and to determine if circulating vitamin D was correlated with body composition, BMD, dietary calcium and vitamin D intake in triathletes. The second purpose was to determine if triathletes have a different level of serum vitamin D, body composition, BMD, dietary calcium and vitamin D intake then non-athletes. The third purpose was to determine if BMD was correlated with body composition (body mass, percent body fat, BMI) in triathletes.

Methods: …

Predicting Chest Press Strength From A 4rm Triceps Brachii Exercise In Trained Women, Krystina Nadia Moschella

UNLV Theses, Dissertations, Professional Papers, and Capstones

Determining maximal strength is important when developing a resistance exercise program for trained athletes. The most frequent strength procedure used to evaluate maximum strength is the 1RM test. However, risk of injury from a 1RM test increases for the athletes, therefore a 4RM test is used in the following study. The purpose of the study is to test whether there is a linear relationship between the bench press and the triceps rope extension exercise. A secondary purpose is the development of a prediction equation for the purpose of prescribing bench press exercise loads from triceps brachii loads using a 4RM …

You Should Know Jack: A Qualitative Study Of The Jack Lalanne Show (1951-~1965), Robert Cochrane

UNLV Theses, Dissertations, Professional Papers, and Capstones

Jack LaLanne hosted the first and longest running fitness program in United States broadcast history from 1951 through 1985. Since LaLanne's rise as a broadcasting celebrity, the health and fitness industry has grown from a small, somewhat-maligned field into a multi-billion dollar per year economy of its own. As LaLanne reached iconic status through his show, his name became synonymous with good health and nutrition, but the messages of his show went far beyond simple exercises. He used religious, patriotic, and biomedical messages to get his points across. In addition, he was a showman who sang to his audience, used …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The increasing rates of obesity continue to threaten the vitality of our nation. Health care costs are soaring and chronic diseases are reaching even the youngest populations. Physical activity is an integral component in reversing the obesity epidemic and improving the health of today's workforce. The present study sought to determine the effect of a work site exercise program on select fitness and psychological parameters. Five female employees participated in a six-week exercise program utilizing HealthBeat(TM) outdoor exercise equipment in a circuit fashion for 30 minutes, 2 days per week. Eighty percent of participants were categorized as sedentary or low-active …

Examining Activity Levels And Motor Proficiency: A Comparison Of Children Who Are Overweight And At A Healthy Weight To Their Parents And Peers, Aaron Copeland, Maresa Madsen, Riley Phelps, Brandon Richards

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: The purpose of this study was to examine relationships and differences between motor proficiency, activity level, and parental activity level in children who are at a healthy weight and children who are overweight or obese.

Methods: Forty-four children (26 children at a healthy weight and 18 children who were overweight or obese) between the ages of 8-16 (BMI: 14.3-43.6 kg/m2) and 36 parents (BMI: 18.1-44.7) participated in this study. Children and parents wore StepWatch activity monitors (SAM) to measure activity levels over a 72 hour period. Tests reflecting several determinants of motor performance were also administered to …
