The activPALTM Accurately Classifies Activity Intensity Categories in Healthy Adults
PHYSICAL ACTIVITY AND SEDENTARY BEHAVIOR MEASUREMENT VALIDITY ACCELEROMETERS
2018/4/24
The activPALTM (AP) monitor is well established for distinguishing sitting, standing, and stepping time. However, its validity in predicting time in physical activity intensity categories in a free-li...
The Effect of Age on the V˙O2max Response to High-Intensity Interval Training
AGING V˙O2max HEART RATE TRAINING STATUS ENDURANCE TRAINING HIIT
2018/4/24
Purpose High-intensity interval training (HIIT) is documented to yield effective improvements in the cardiovascular system and be an excellent strategy for healthy aging. However, it is not determined...
High-Intensity Interval Training Increases Cardiac Output and V˙O2max
INTERVAL EXERCISE MAXIMAL OXYGEN UPTAKE STROKE VOLUME THORACIC IMPEDANCE FICK EQUATION CYCLE ERGOMETRY
2018/4/24
Increases in maximal oxygen uptake (V˙O2max) frequently occur with high-intensity interval training (HIIT), yet the specific adaptation explaining this result remains elusive.
Purpose This study exam...
Cardiorespiratory and Metabolic Responses to Loaded Half Squat Exercise Executed at an Intensity Corresponding to the Lactate Threshold
Aerobic fitness/VO anaerobic threshold exercise physiology strength training
2016/1/9
This study was designed to identify the blood lactate threshold (LT2) for the half squat (HS) and to examine cardiorespiratory and metabolic variables during a HS test performed at a work intensity co...
Menstrual cycle phase and carbohydrate ingestion alter immune response following endurance exercise and high intensity time trial performance test under hot conditions
Prolonged exercise Leukocytes Cytokines
2015/7/29
We investigated the effects of menstrual cycle phase and carbohydrate (CHO) ingestion on immune response during endurance exercise at 30°C. Six healthy women completed 4 trials comprising 90 min of cy...
The effects of phosphatidylserine on endocrine response to moderate intensity exercise
endocrine response moderate intensity exercise
2015/7/14
Previous research has indicated that phosphatidylserine (PS) supplementation has
the potential to attenuate the serum cortisol response to acute exercise stress. Equivocal findings
suggest that this...
The effects of creatine pyruvate and creatine citrate on performance during high intensity exercise
creatine pyruvate creatine citrate
2015/7/13
A double-blind, placebo-controlled, randomized study was performed to evaluate
the effect of oral creatine pyruvate (Cr-Pyr) and creatine citrate (Cr-Cit) supplementation on
exercise performance in ...

Exercise Intensity of Recreational Sport: Impacts of Sex and Fitness
The traditional model sports running biking in the general population healthy high intensity exercise aerobic exercise
2015/5/12
Adherence to traditional modes of exercise (running or cycling) in the general population is low. Sport is proposed as an alternative form of exercise that may in-duce similar health benefits while be...
Effects of High Intensity Training and Continuous Endurance Training on Aerobic Capacity and Body Composition in Recreationally Active Runners
Aerobic power lactate threshold VO peak endurance running aerobic training
