Cardiorespiratory Effects of One-Legged High-Intensity Interval Training in Normoxia and Hypoxia:A Pilot Study
Local muscle training altitude training exercise physiology
2016/7/7
A higher-than-average maximal oxygen consumption (VO2max), is closely associated with decreased morbidity and mortality and improved quality of life and acts as a marker of cardiorespiratory fitness. ...
Sex-Related Differences in Self-Paced All Out High-Intensity Intermittent Cycling:Mechanical and Physiological Responses
Oxygen uptake sexual dimorphism anaerobic power reserve
2016/7/7
The purpose of this study was to compare sex-related responses to a self-paced all out high-intensity intermittent exercise (HIIE). 9 women and 10 men were submitted to a maximal incremental test (to ...
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...
High-Intensity Running and Energy Restriction Reduce Postprandial Lipemia in Girls
CARDIOVASCULAR DISEASE RISK ENERGY DEFICIT EXERCISE INTENSITY TRIACYLGLYCEROL YOUNG PEOPLE
2017/4/13
Purpose: This study examined the potency of combining acute high-intensity exercise and energy intake restriction on postprandial triacylglycerol concentrations ([TAG]) in healthy girls.
Methods: Six...
Muscle Pain as a Regulator of Cycling Intensity: Effect of Caffeine Ingestion
EXERCISE PERRORMANCE ADENOSINE ANTAGONISM
2017/4/13
Caffeine ingestion improves endurance time trial performance. However, the ergogenic mechanism of action remains unresolved. One potential explanation for caffeine’s performance-enhancing effect is an...
Acute Physiological Responses to Short- and Long-Stage High-Intensity Interval Exercise in Cardiac Rehabilitation:A Pilot Study
intermittent exercise exercise prescription acute effects health-related markers heart disease patients
2016/3/11
Despite described benefits of aerobic high-intensity interval exercise (HIIE), the acute responses during different HIIE modes and associated health risks have only been sparsely discovered in heart d...
The Total Work Measured During a High Intensity Isokinetic Fatigue Test Is Associated With Anaerobic Work Capacity
Isokinetic dynamometry muscle fatigue Wingate anaerobic test cyclists physiological assessmen
2016/3/11
The purpose of the study was to determine whether total work measured during a high intensity isokinetic fatigue test (TWFAT) could be considered as a valid measure of anaerobic work capacity (AWC), s...
Sodium bicarbonate intake improves high-intensity intermittent exercise performance in trained young men
Fatigue Yo-Yo IR2 performance Blood pH and lactate Plasma potassium Buffer capacity
2015/7/30
Sodium bicarbonate intake has been shown to improve exercise tolerance, but the effects on high-intensity intermittent exercise are less clear. Thus, the aim of the present study was to determine the ...
High-intensity interval training and β-hydroxy-β-methylbutyric free acid improves aerobic power and metabolic thresholds
High-intensity interval training β-Hydroxy-β-Methylbutyric free acid Aerobic Endurance VO2peak Respiratory compensation point Ventilatory threshold
2015/7/29
Previous research combining Calcium β-hydroxy-β-methylbutyrate (CaHMB) and running high-intensity interval training (HIIT) have shown positive effects on aerobic performance measures. The purpose of t...
Low-intensity and moderate exercise training improves autonomic nervous system activity imbalanced by postnatal early overfeeding in rats
Moderate exercise training Overfeeding-induced obesity Autonomic nervous system Parasympathetic nervous system Glucose homeostasis
2015/7/29
Postnatal early overfeeding and physical inactivity are serious risk factors for obesity. Physical activity enhances energy expenditure and consumes fat stocks, thereby decreasing body weight (bw). Th...
Combined effect of branched-chain amino acids and taurine supplementation on delayed onset muscle soreness and muscle damage in high-intensity eccentric exercise
Double-blind study Amino acids Combined supplementation BCAA Taurine DOMS
2015/7/28
Previous studies have evaluated the effectiveness of branched-chain amino acid (BCAA) supplementation for preventing delayed onset muscle soreness (DOMS) and muscle damage induced by eccentric exercis...

HX108-CS Schisandra chinensis Chaenomeles sinensis Endurance capacity Exercise capacity Lactate accumulation
2015/7/27
In the present study, we determined the effects of HX108-CS (mixed extract of Schisandra chinensis and Chaenomeles sinensis) supplementation on lactate accumulation and endurance capaci...
The differential effects of a complex protein drink versus isocaloric carbohydrate drink on performance indices following high-intensity resistance training:a two arm crossover design
Isocaloric carbohydrate Protein drink/beverage Performance Repeated-bout Nutrient timing
2015/7/27
Post-workout nutrient timing and macronutrient selection are essential for recovery, glycogen replenishment and muscle protein synthesis (MPS). Performance repeatability, particularly after strenuous ...
