UNLABELLED ENDURANCE ATHLETES INTEGRATE FOUR CONDITIONING CONCEPTS IN THEIR TRAINING PROGRAMS: high-volume training (HVT), "threshold-training" (THR), high-intensity interval training (HIIT) and a combination of these aforementioned concepts known as polarized training (POL). The purpose of this study was to explore which of these four training concepts provides the greatest response on key com...

Neutrophils and monocytes are key components of the innate immune system that undergo age-associated declines in function. This study compared the impact of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on immune function in sedentary adults. Twenty-seven (43 ± 11 years) healthy sedentary adults were randomized into ten weeks of either a HIIT (>90% ma...

Due to the current obesity epidemic in the United States, there is growing interest in efficient, effective ways to increase energy expenditure and weight loss. Research has shown that high-intensity exercise elicits a higher Excess Post-Exercise Oxygen Consumption (EPOC) throughout the day compared to steady-state exercise. Currently, there is no single research study that examines the differe...

the aim of this study was to investigate the effect of a period of interval training and step taper on weight changes and endurance performance in male rats during puberty. in this experimental study, 40 male wistar rats (3 weeks old) were randomly divided into exercise and control groups. after 6 weeks of incremental interval training, exercise group was divided in to 3 groups of 3-week taper ...

Background and objectives: Previous investigations have shown that physical activity can improve insulin sensitivity and body composition by reducing the concentration of inflammatory biomarkers. The study aimed at evaluating effects of eight weeks of resistance training and high-intensity interval training on adropin, blood glucose markers, and body composition in overweight females. Methods:...
