Poor sleep and low physical activity levels (PA) are risk factors for several diseases. A recent study showed that the combined effects of insomnia and low PA increase the risks further. But short, go...
Low-Force Muscle Activity Regulates Energy Expenditure after Spinal Cord Injury
DIABETES OBESITY ELECTRICAL STIMULATION EXERCISE METABOLISM
2018/4/24
Reduced physical activity is a primary risk factor for increased morbidity and mortality. People with spinal cord injury (SCI) have reduced activity for a lifetime, as they cannot volitionally activat...
Voluntary Running Attenuates Metabolic Dysfunction in Ovariectomized Low-Fit Rats
EXERCISE OVARIECTOMY INSULIN SENSITIVITY AMPK SKELETAL MUSCLE METABOLISM
2018/4/24
Introduction Ovariectomy and high-fat diet (HFD) worsen obesity and metabolic dysfunction associated with low aerobic fitness. Exercise training mitigates metabolic abnormalities induced by low aerobi...
Enhanced Endurance Performance by Periodization of Carbohydrate Intake: Sleep Low Strategy
DIETARY MANIPULATION CARBOHYDRATES TRIATHLETES EXERCISE–NUTRIENT INTERACTIONS
2017/4/13
Purpose: We investigated the effect of a chronic dietary periodization strategy on endurance performance in trained athletes.
Methods: Twenty-one triathletes (V˙O2max: 58.7 ± 5.7 mL·min−1·kg...
Increased Hypoxic Dose After Training at Low Altitude with 9h Per Night at 3000m Normobaric Hypoxia
Hypoxia hemoglobin mass live high: train low athletic performance peak oxygen uptake
2016/2/23
This study examined effects of low altitude training and a live-high: train-low protocol (combining both natural and simulated modalities) on haemoglobin mass (Hbmass), maximum oxygen consumption (VO2...
A Practical Model of Low-Volume High-Intensity Interval Training Induces Performance and Metabolic Adaptations That Resemble ‘All-Out’ Sprint Interval Training
Wingate test repeated sprints blood lactate training adaptations
2015/5/7
Recently, a novel type of high-intensity interval training known as sprint interval training has demonstrated increases in aerobic and anaerobic performance with very low time commitment. However, thi...
A Low-Cost Contact System to Assess Load Displacement Velocity in a Resistance Training Machine
Velocity testing strength training speed events
2015/5/7
This study sought to determine the validity of a new system for assessing the displacement and average velocity within machine-based resistance training exercise using the Chronojump System. The new d...
Selective Activation of the Rectus Abdominis Muscle During Low-Intensity and Fatiguing Tasks
Motor control electromyography biomechanics exercise
2015/5/7
In order to understand the potential selective activation of the rectus abdominis muscle, we conducted two experiments. In the first, subjects performed two controlled isometric exercises: the curl up...
Effects of warm-up on vertical jump performance and muscle electrical activity using half-squats at low and moderate intensity
EMG contrast training resistance exercise
2015/5/5
The purpose of this study was to determine the effects of a
specific warm-up using half-squats at low and moderate intensity on vertical jump performance and electromyographic activity of the thigh ...
Kinematic Description of Elite Vs. Low Level Players in Team-Handball Jump Throw
3D-kinematics angular velocity ball throwing technique ball release speed
2015/5/4
The jump throw is the most applied throwing technique in team- handball (Wagner et al., 2008); however, a comprehensive analysis of 3D-kinematics of the team-handball jump throw is lacking. Therefore,...
Trunk Rotation and Weight Transfer Patterns between Skilled and Low Skilled Golfers
Golf kinematic kinetic skill level
2015/5/4
The purpose of this study was to examine trunk rotational patterns and weight transfer patterns that may differentiate swing skill level in golfers. Thirteen skilled golfers (mean handicap = 0.8 ± 2.6...
Is There a Gradient of Mortality Risk among Men with Low Cardiorespiratory Fitness?
