Relationship Between Breakfast And Basketball Shooting Accuracy, Dimitrije Cabarkapa
Relationship Between Breakfast And Basketball Shooting Accuracy, Dimitrije Cabarkapa
Masters Theses, 2010-2019
Purpose: The purpose of this study was to determine if collegiate and recreational basketball players shooting accuracy improved after consumption of breakfast (BF) compared to no-breakfast (No-BF).
Methods: 24 male and female collegiate and recreational basketball players completed a three-week intervention study with a crossover design. Subjects were randomly assigned to a four-day BF or No-BF treatment starting on Monday and completed testing that included a free-throw drill and timed 2-point and 3-point drills on day four. Treatment switched the following Monday. Food intake records were collected during each treatment phase.
Results: There was no difference between BF and No-BF …
The Effects Of Coffee Ingestion On The Acute Testosterone Response To Exercise, Taylor Landry
The Effects Of Coffee Ingestion On The Acute Testosterone Response To Exercise, Taylor Landry
Masters Theses, 2010-2019
Abstract
This study investigated the effects of coffee ingestion (COF) on serum testosterone responses to exercise in recreationally weight-trained males. Subjects ingested either 12 ounces of 6mg/kg caffeinated coffee (COF), decaffeinated coffee (DEC), or water (PLA) one hour prior to exercise in a randomized, within-subject, crossover design. The exercise session consisted of 21 minutes of high intensity interval cycling (alternating intensities corresponding to two minutes at power outputs associated with 2.0 mmol/L lactate and 4.0 mmol/L lactate) followed by resistance exercise (7 exercises, 3 sets of 10 repetitions, 65% 1RM, 1-minute rest periods). Subjects also completed repetitions to fatigue tests …
The Effect Of Menstrual Phase And Oral Contraceptive Steroids On Caffeine During Cycling Performance, Annette M. Lemanski
The Effect Of Menstrual Phase And Oral Contraceptive Steroids On Caffeine During Cycling Performance, Annette M. Lemanski
Masters Theses, 2010-2019
PURPOSE: There is evidence that female sex hormones impact caffeine metabolism, with decreased CYP1A2 activity and diminished caffeine clearance in women with higher estrogen levels. Therefore, the objectives of this project were to determine the effects of oral contraceptives and menstrual cycle on the benefits of caffeine supplementation for cycling performance. METHODS: Sixteen recreationally trained female cyclists, oral contraceptive steroid (OCS) users (n=8, age = 21.4 ± 1.4 years, height = 168.4 ± 3.6 cm, weight = 63.6 ± 7.2kg, VO2max = 48.0 ± 4.0 ml/kg/min), and non-users (n=8, age = 20.9 ± 2.1 years, height = 161.0 ± …
A Low-Carbohydrate Ketogenic Diet Combined With Six Weeks Of Crossfit Training Improves Body Composition And Performance, Rachel M. Gregory
A Low-Carbohydrate Ketogenic Diet Combined With Six Weeks Of Crossfit Training Improves Body Composition And Performance, Rachel M. Gregory
Masters Theses, 2010-2019
A low-carbohydrate ketogenic diet (LCKD) is a popular approach to weight and fat loss. CrossFit is a high-intensity power training (HIPT) type exercise for all levels of age and fitness that has gained recognition as one of the fasting growing sports in America. No previous research has been found which examines body composition changes or performance in individuals consuming a LCKD and participating in CrossFit training. PURPOSE: The purpose of this research was to examine the effects of a 6-week LCKD and CrossFit program on body composition and performance. METHODS: Twenty-seven non-elite CrossFit subjects (mean ± SD age = …
The Psychological Response To A Low Carbohydrate Ketogenic Diet In Combination With A Six-Week Strength Training Protocol, Matthew T. Thorp
The Psychological Response To A Low Carbohydrate Ketogenic Diet In Combination With A Six-Week Strength Training Protocol, Matthew T. Thorp
Masters Theses, 2010-2019
The aim of the present study was to determine whether or not long-term adherence to a Low-Carbohydrate Ketogenic Diet (LCKD) combined with a powerlifting strength training protocol could produce a positive psychological response. This six-week randomized control trial consisted of a treatment (LCKD) group (7% carbohydrates, 50% fat and 45% protein) and a control (CON) group (ad libitum). Both groups completed a validated powerlifting training protocol, as well as the Hospital Anxiety and Depression Scale and the Profile of Mood States. Multivariate testing and general linear modeling statistical analyses were used to compare psychological response between groups (p < 0.05) and found that there was a significant decrease in anxiety over the duration of six-weeks among both groups. No other psychological responses, including negative responses, were found to be significant. All participants significantly improved one-repetition max bench press, back squat, and deadlift (p < 0.05). The main findings of this study suggest that some positive psychological responses exist from long-term LCKD adherence, as well as potential increases in strength performance.
