The effects of total sleep deprivation and ammonia inhalants on the cognitive and physical abilities of military personnel
Maleček, Jan ; Tufano, James Joseph (advisor) ; Conkright, William (referee) ; Kročová, Zuzana (referee)
Given that this dissertation is built up upon three sequential studies, the objectives, methods and results of the thesis are accordingly divided into three distinct subsections (a, b, and c), each corresponding to an individual study. Title: The effects of total sleep deprivation and ammonia inhalants on the cognitive and physical abilities of military personnel Objectives: a) Conducting a literature review to identify the current understanding on the topic and substantial gaps in the literature by investigating the impact of ammonia inhalations on cognitive and physical performance. b) Conducting a methodological study to examine lacking test-retest reliability of standard-issued static and dynamic military shooting protocols for comprehensive investigation of the of total sleep deprivation impact and ammonia inhalants on handgun shooting accuracy. c) Conducting a control trial study to investigate the effectiveness of ammonia inhalants in altering the impact of 36 hours of total sleep deprivation on battery of cognitive and physical performance tests relevant for military personnel. Methods: a) For the purpose of this literature review, a search of the following electronic databases by the author JM was performed: MEDLINE by PubMed, SCOPUS, Web of Science, and Google Scholar. Due to the paucity...

Evaluating Methods of Assessing Force and Velocity during Punching Specific Movements
Omcirk, Dan ; Tufano, James Joseph (advisor) ; Reguli, Zdenko (referee) ; Fernandes, John (referee)
Title: Evaluating Methods of Assessing Force and Velocity during Punching Specific Movements Objectives: This dissertation had three main objectives: 1. To determine the ability of different commercially available punch trackers (Corner, Everlast, and Hykso) to recognize specific punch types (lead and rear straight punches, lead and rear hooks, and lead and rear uppercuts) thrown by trained and untrained punchers. 2. To determine the validity of three commercially available punch trackers (Corner, Hykso, and StrikeTec) for monitoring punch velocity and force during rear straight punches, rear hooks, and rear uppercuts performed at lower and higher intensities by trained and untrained punchers. 3. To determine the reliability and load-velocity profiles of three different landmine punch throw variations (seated without trunk rotation [LPwo], seated with trunk rotation [LPw], and standing whole body [LP]) with different loads (20.0 kg, 22.5 kg, and 25.0 kg), all with the dominant (DH) and non-dominant hand (NH). Methods: Due to three independent studies in this dissertation, the methods are divided into three sections, each connected to the objectives mentioned above: 1. Ten trained and 11 untrained punchers different punch combinations, and punch trackers data were compared to data from video...

Kinematic and dynamic characteristics of straight punches in elite male boxers
Pádecký, Jan ; Tufano, James Joseph (advisor) ; Pavelka, Radim (referee)
Title: Kinematic and dynamic characteristics of straight punches in elite male boxers Objectives: The purpose of this study was to quantify lower limb forces in the x, y, and z directions and their association with jab and cross relative peak force, and jab and cross peak velocity. Methods: A sample of 12 elite male subjects participated in the present study, which took place over two days. Subjects were familiarized with the procedures during the first day. During the second day, the subjects performed a standardized warm-up protocol, followed by one straight punch with the rear and then the lead hand to a force plate that was suspended in the air at the chin level by a cable system. The subjects were standing on two separate tri-axial force plates. Punch velocity was assessed using a Qualisys Motion Tracking Manager, where the marker used was placed in the middle of 12 OZ gloves. Results: Subject body weight resulted in a high positive significant correlation with jab and cross peak force, and a non-significant low and moderate positive correlation with jab and cross peak velocity, respectively. Partial correlation controlling for bodyweight resulted in a very high positive significant correlation between jab peak velocity and jab peak force and a high positive, but the non-significant...

Effect of cannabis in sports training
Yücel, Yalın ; Tufano, James Joseph (advisor) ; Šteffl, Michal (referee)
Title: Effect of cannabis in sports training. Objectives: * Present the physiological and psychological effects of cannabis on human body. * Identify harmful and beneficial effects of cannabis consumption in people who partake in recreational sporting activities as well as competitive athletes. * Identify the perception of cannabis use in the sports world. Methods: * Detailed literature research on cannabis and its primary components. * Literature research on scientific requirements of sports training. * Systematic review of previous surveys and experiments regarding the effects of cannabis on sports exercise parameters. * Preparing a questionnaire for sportspeople (current and former Turkish and Czech American football players in general) and analyzing the results. Results: * There hasn't been many recent scientific research about the specific effects of cannabis ingestion in sports performance. * There are some beneficial attributes of cannabis in sport training as well as performance hindering attributes and potentially dangerous side effects. * Questionnaire participants generally do not think cannabis is a performance- enhancing substance. * There exists contrary opinions, beliefs and scientific evidence on almost all of the aspects of cannabis and its use in sport. Keywords: cannabis, sport,...

Obstacle course racing: the effect of obstacles on the total race time during a Spartan Race
Kozmová, Monika ; Tufano, James Joseph (advisor) ; Šteffl, Michal (referee)
Title: Obstacle course racing: the effect of obstacles on the total race time during a Spartan Race Objectives: The aim of this study was to determine the effect of 30-burpee punishment on subsequent running speed (SPD), heart rate (HR) following a missed obstacle, and the final race standings during a OCR race. Methods: In our thesis we used a method of analysis in an official Spartan Race in the Czech Republic. 11 male OCR competitors wore a GPS and HR monitor, from which HR and SPD were measured. Three specific obstacles were chosen where nearly all competitors did burpees (spear throw), half did burpees (traverse wall), and nearly none did burpees (monkey bars). The HR and SPD were measured during the entire race, and specifically noted when the competitors arrived at left the obstacle. Results: The average HR of the entire race was 166.45 ± 3.34 beats per minute. The average time spent at the successful obstacles without burpees was 23 ± 17 seconds, while the average time spent at the unsuccessful obstacles with burpees was 124 ± 11 seconds. The change in HR over the course of successful obstacles was 0.79 ± 3.69 beat per minute, while the change in HR during unsuccessful obstacles with burpees was -3.00 ± 6.70 beat per minute. Total time spent at each obstacle correlated with the final...
