EXERCISE SEDENTARY LIFESTYLE OBESITY CENTRAL ADIPOSITY PROSPECTIVE STUDIES
2017/4/13
Purpose: Both moderate-to-vigorous physical activity (MVPA) and sedentary behavior can be associated with adult adiposity. Much of the relevant evidence is from cross-sectional studies or from prospec...
Effects of Oral Contraceptive Use on Anterior Cruciate Ligament Injury Epidemiology
SOCCER KNEE INJURY PREVENTION EPIDEMIOLOGY
2017/4/13
Introduction/Purpose: Anterior cruciate ligament injuries often incur major consequences for athletes. Elevated estrogen levels are likely increase the risk for injury. This risk may be partially or f...
Cycling Time Trial Is More Altered in Hypobaric than Normobaric Hypoxia
NORMOBARIC HYPOXIA HYPOBARIC HYPOXIA PERFORMANCE EXERCISE
2017/4/13
Purpose: Slight physiological differences between acute exposure in normobaric hypoxia (NH) and hypobaric hypoxia (HH) have been reported. Taken together, these differences suggest different physiolog...
The Effect of Heterozygosity for the ACTN3 Null Allele on Human Muscle Performance
HETEROZYGOUS QUANTITATIVE TRAIT LOCI
2017/4/13
α-Actinin-3 is primarily expressed in fast (Type II) fibers in the human skeletal muscle. Over 70% of the global population has at least one copy of a loss of function allele because of a premature st...
Calorie Estimation in Adults Differing in Body Weight Class and Weight Loss Status
BODY MASS INDEX WEIGHT LOSS ENERGY EXPENDITURE ENERGY INTAKE EXERCISE INTENSITY
2017/4/13
Purpose: Ability to accurately estimate calories is important for weight management, yet few studies have investigated whether individuals can accurately estimate calories during exercise or in a meal...
Modeling Intermittent Cycling Performance in Hypoxia Using the Critical Power Concept
ALTITUDE WORK-BALANCE HIGH-INTENSITY FATIGUE
2017/4/13
Purpose: This study investigated the efficacy of an intermittent critical power (CP) model, termed the “work-balance” (W′BAL) model, during high-intensity exercise in hypoxia (HYPO).
Methods: Eleven ...
A Catecholamine Precursor Does Not Influence Exercise Performance in Warm Conditions
DOPAMINE NOREPINEPHRINE DOPING CENTRAL FATIGUE SINEMET
2017/4/13
Purpose: Acute doses of Sinemet® (l-DOPA combined with carbidopa) previously failed to influence prolonged exercise performance in a temperate environment, but it is not known whether acute doses...

FASCICLE MUSCLE ADAPTATION HAMSTRING
2017/4/13
Purpose: To determine the architectural adaptations of the biceps femoris long head (BFlh) after concentric or eccentric strength training interventions and the time course of adaptation during traini...
Comparison of Three Popular Exercise Modalities on VO2max in Overweight and Obese
HIIT MICT RUNNING AEROBIC CAPACITY V˙O2max
2017/4/13
Introduction: In this prospective randomized trial, we examined the effect of three popular exercise training modalities on maximal oxygen uptake (V˙O2max) in overweight and obese individuals. In addi...
Low-Active Male Adolescents: A Dose Response to High-Intensity Interval Training
YOUTH HEALTH PHYSICAL ACTIVITY FITNESS
2017/4/13
Purpose: High-intensity interval training (HIIT) is a potential alternative to traditionally recommended steady state exercise for providing health benefits in adolescents, yet its dose–response relat...
