Influence Of Post-Exercise Nutrient Intake On Recovery And Subsequent Exercise Performance In Youth Cyclists, Andrew Law
Influence Of Post-Exercise Nutrient Intake On Recovery And Subsequent Exercise Performance In Youth Cyclists, Andrew Law
Masters Theses, 2010-2019
Purpose: The purpose of this study was to determine if chocolate milk (CM) consumption after high-intensity cycling exercise affects post-exercise recovery and subsequent exercise performance in youth cyclists, compared to a carbohydrate-only (CHO) and a placebo (PL) beverage. Methods: Eight youth cyclists (15-18 y, VO2peak = 61.8 ± 7.7 mL·kg-1·min-1) performed an exercise/recovery protocol consisting of 2 bouts of exercise, on 3 separate occasions, in a randomly counterbalanced crossover design. The first exercise bout (EX1) consisted of 30 min of constant-load cycling (40-60% Wmax), and 60 min of high-intensity intervals (alternating 2 min …
Circulating Microrna Following High Intensity Interval Cycling With And Without Post-Exercise Nutrient Consumption, Jeremy Via
Masters Theses, 2010-2019
Introduction: MicroRNA (miRNA) are small, non-coding RNA that act post-transcriptionally to regulate gene expression. miRNA levels are modulated by acute aerobic exercise, yet little is known about how miRNA levels may change in response to high-intensity interval exercise. Further, almost nothing is known about the impact of post-exercise nutrition (carbohydrate and/or protein) on miRNA levels. Thus, the purpose of this study is to examine the effects of high-intensity interval cycling and different post-exercise nutrients on ci-miRNA levels. Methods: Nine recreationally active males (age 21.9 ± 2.0yrs; VO2max 49.6 ± 4.0mL/kg/min) competed three trials, each including identical exercise protocols. Protocol …
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 = …
A Single Night Of Sleep Restriction Impairs Recovery From Heavy Exercise, John D. Chase
A Single Night Of Sleep Restriction Impairs Recovery From Heavy Exercise, John D. Chase
Masters Theses, 2010-2019
We examined the effects of one night of sleep restriction (Sleep-; 2.5 hrs) on subsequent 3-km cycling performance and skeletal muscle recovery from heavy exercise compared to a full night of rest (Sleep+; 7 hrs). Seven recreational cyclists (n=6 male, n=1 female; age = 24.4 ± 7 yrs; height = 170 ± 10 cm; weight = 68 ± 13 kg VO2max = 61.5 ± 4.4 ml/kg/min) completed four simulated 3-km time trials (TT) and six peak isokinetic torque trials at different speeds (30 and 120°/sec) under both conditions. The first exercise trial (EX1) consisted …
The Effect Of Sleep Restriction On Coagulation And Fibrinolysis After Heavy Exercise, Paul A. Roberson
The Effect Of Sleep Restriction On Coagulation And Fibrinolysis After Heavy Exercise, Paul A. Roberson
Masters Theses, 2010-2019
Introduction: Research has shown exercise elicits a hemostatic response affecting coagulation and fibrinolysis. Furthermore, prior research has determined circadian fluctuations exist where clotting potential increases in the morning as a result of increased PAI-1 and decreased tPA which is further exacerbated by exercise. These circadian fluctuations and exercise responses have the potential to be accentuated by poor sleep. The purpose of this study is to determine the effects of sleep restriction on tPA activity, PAI-1 activity, and Factor VIII antigen activity (FVIII) while resting and after exercise.
Methods: 7 Subjects underwent two similar exercises sessions (EX). EX1 occurred in the …
The Effect Of Run Sprint Interval Training On Diabetic Metabolic Markers In Prediabetic Adults, Kathryn L. Hilovsky
The Effect Of Run Sprint Interval Training On Diabetic Metabolic Markers In Prediabetic Adults, Kathryn L. Hilovsky
Masters Theses, 2010-2019
Abstract
Purpose: The primary purpose of this study was to compare the effects of an 8-week run-sprint interval training (R-SIT) and continuous moderate-intensity training (MIT) on fasting blood glucose, HbA1c, insulin sensitivity, and β-cell function in sedentary, prediabetic adults. Secondary outcomes of the study included anthropometric, body composition variables, and aerobic capacity.
Methods: Sedentary, physician diagnosed prediabetic individuals were randomized into R-SIT (n=7, BMI 36.76 ± 9.79) or MIT (n=8, BMI 40.59 ± 12.49) interventions. Subjects participated in supervised exercise three times a week and attended a Diabetes Prevention Program course, once weekly. R-SIT participants performed 4-6 x 30-second …
