New research in healthy volunteers indicates that high-intensity interval training stimulates muscle cells to boost production of mitochondrial proteins and delay the aging process at the molecular level. The Cell Metabolism findings are encouraging because with age, the energy-generating capacity of cells’ mitochondria slowly decreases. To examine the molecular players involved in the benefits...

The purpose of the presented study was to compare acute and post-exercise differences in cardiorespiratory, metabolic, cardiac autonomic, inflammatory and muscle damage responses to highintensity interval exercise (HIIT) between endurance and sprint athletes. The study group consisted of sixteen highly-trained males (age 22.1 ± 2.5 years) participating in endurance (n = 8) or sprint (n = 8) spo...

It is well documented that cardiorespiratory exercise, as well as muscular strength and endurance exercise, have a positive impact on a person’s health [1]. Many positive health benefits arise from moderate intensity exercise including decreased risk of heart disease, cancer, stroke, osteoporosis, and diabetes found in individuals who engage in regular physical activity [1]. The cardiovascular ...

In individuals without diabetes, highintensity exercise (HIE) training may reduce (1) the characteristic postexercise rise in plasma glucose with HIE (2–4) and reduces (5,6) the marked acid-base balance perturbations (5–8). In type 1 diabetes, continuous HIE induces sustained hyperglycemia (9,10), while very brief intermittent HIE may reduce hyperglycemia (11). Acid-base disturbances during exe...

some important compatibility that occur with exercise is increase of the capillary density or angiogenesis. vascular endothelial growth factor (vegf) have mitogen role for endothelial cells and consider an important intermediary angiogenesis process. the purpose of this study was comparing the effect of two type of physical activity on response of serum vegf-a in non-athlete men. for this aim 1...

Regular endurance training improves performance during tasks that rely mainly on aerobic energy metabolism, in large part by increasing the body’s ability to transport and utilize oxygen and by altering substrate metabolism in working skeletal muscle (Saltin & Gollnick, 1983). In contrast, highintensity “sprint”-type exercise training is generally thought to have less of an effect on oxidative ...
