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...
The Mechanoreflex and Hemodynamic Response to Passive Leg Movement in Heart Failure
BLOOD FLOW MECHANORECEPTORS PASSIVE LEG MOVEMENT MUSCLE AFFERENTS
2017/4/13
Background: Sensitization of mechanosensitive afferents, which contribute to the exercise pressor reflex, has been recognized as a characteristic of patients with heart failure (HF); however, the hemo...
Myokine Expression in Muscle and Myotubes in Response to Exercise Stimulation
MYOSTATIN CYTOKINE INTERLEUKIN MYOBLAST ENDURANCE
2017/4/13
Purpose: Myokines have been shown to affect muscle physiology and exert systemic effects. We endeavored to investigate a panel of myokine mRNA expression after a single exercise bout (studies 1 and 2)...
A Comparison between Alpine Skiing, Cross-Country Skiing and Indoor Cycling on Cardiorespiratory and Metabolic Response
Borg blood lactate cross-country skiing cycling energy expenditure fitness level oxygen uptake gender
2016/3/11
Since physical inactivity especially prevails during winter months, we set out to identify outdoor alternatives to indoor cycling (IC) by comparing the metabolic and cardiorespiratory responses during...

acute garlic supplementation fibrinolytic vasoreactive exercise
2015/7/30
The purpose of this project was to examine the effects of acute garlic supplementation on fibrinolysis and vasoreactivity both at rest and following maximal exercise.Eighteen healthy trained males (20...
The influence of commercial energy shots on response time and power output in recreational cyclists
Performance Energy shots Caffeine Taurine Carbohydrates
2015/7/29
Caffeine based energy shot products accounted for $1.3 billion in sales in 2011. Caffeine has been shown to confer numerous benefits during exercise and is oftentimes combined with ingredients such as...
The effect of an acute antioxidant supplementation compared with placebo on performance and hormonal response during a high volume resistance training session
Fatigue Ergogenic Response Anabolic Exercise
2015/7/29
Antioxidant supplementation is known to increase human endogenous antioxidant (AOX) capacity providing a means of blunting exercise induced reactive oxygen species (ROS). The purpose of this study was...
Dietary nucleotide improves markers of immune response to strenuous exercise under a cold environment
Exercise Dietary nucleotides Lymphocyte proliferation
2015/7/27
Strenuous exercise has been classically associated to immune-suppression and consequently to an increased risk of infections, especially at the upper respiratory tract. The administration of dietary n...
Gene Response of the Gastrocnemius and Soleus Muscles to an Acute Aerobic Run in Rats
Aerobic exercise skeletal muscle gene response
2015/5/7
Genes can be activated or inhibited by signals within the tissues in response to an acute bout of exercise. It is unclear how a particular aerobic exercise bout may influence two muscles with similar ...
ACTN3 R577X Polymorphism and Neuromuscular Response to Resistance Training
Muscle strength muscle hypertrophy peak torque genotype alpha-actinin 3 knee extensor
2015/5/7
The R577X polymorphism at the ACTN3 gene has been associated with muscle strength, hypertrophy and athletic status. The X allele, which is associated with the absence of ACTN3 protein is supposed to i...
Does the Level of Graphical Detail of a Virtual Handball Thrower Influence a Goalkeeper’s Motor Response?
Virtual reality level of detail time to respond motor response
2015/4/24
The authors investigated how different levels of detail (LODs) of a virtual throwing action can influence a handball goalkeeper’s motor response. Goalkeepers attempted to stop a virtual ball emanating...
