time dependent effects of high intensity interval training on oxygen uptake kinetics in young males
نویسندگان
چکیده
the aim of this study was to determine time dependent effects of high intensity interval training (hiit) on oxygen kinetics in young males. 40 active students were randomly assigned to four groups: one session of hiit, two sessions of hiit, four sessions of hiit and control. both hiit and control groups performed the incremental test on an ergometer bicycle. two days after the pretest, training groups participated in one, two and four sessions of hiit. two days after the end of the training protocol, posttest was carried out. oxygen kinetics parameters were measured by gas analyzer with breath-by breath method during the protocol, in the pretest and posttest test. the findings showed that one session of hiit had no effects on oxygen kinetic parameters (p>0.05). two sessions of hiit improved some oxygen kinetic parameters such as vo2max, oxygen deficit and time constant 2 (p0.05). in addition, four sessions of hiit improved all oxygen kinetic parameters: vo2max, oxygen deficit, time constant 1 and 2 (p

Time-dependent Effects of High Intensity Interval Training on Oxygen Kinetics in Females
Background. Because VO2max doesn’t provide any detailed information about aerobic examinations Oxygen Kinetic is used for more accuracy. Long intensive and repetitive exercises with sufficient time lead to increase in aerobic parameters like kinetic absorption of oxygen. Objectives. The purpose of this study was to determine time dependent effects of short-time high intensity interval...
متن کاملEffect of High Intensity Interval Training on the Level of Leptin and Liver Enzymes in Obese and Overweight Males
Introduction: Obesity is a complex disorder, which is characterized by excessive accumulation of adipose tissue. Leptin is a peptide hormone, which is basically secreted by adipose tissue and is effective in the regulation of body weight and fat. The purpose of this study was to investigate the effect of high-intensity interval training on the level of Leptin and liver enzymes in obese and over...
متن کاملExtremely short duration high intensity interval training substantially improves insulin action in young healthy males
BACKGROUND Traditional high volume aerobic exercise training reduces cardiovascular and metabolic disease risk but involves a substantial time commitment. Extremely low volume high-intensity interval training (HIT) has recently been demonstrated to produce improvements to aerobic function, but it is unknown whether HIT has the capacity to improve insulin action and hence glycemic control. MET...
متن کاملEffect of short-term high-intensity interval training vs. continuous training on O2 uptake kinetics, muscle deoxygenation, and exercise performance.
The early time course of adaptation of pulmonary O(2) uptake (Vo(2)(p)) (reflecting muscle O(2) consumption) and muscle deoxygenation kinetics (reflecting the rate of O(2) extraction) were examined during high-intensity interval (HIT) and lower-intensity continuous endurance (END) training. Twelve male volunteers underwent eight sessions of either HIT (8-12 x 1-min intervals at 120% maximal O(2...
متن کاملEffects of Low-Intensity Resistance versus High-Intensity Interval Aerobic Training on Serum Interleukin-6 Concentration and Insulin Resistance Markers in Obese and Young Men
Introduction: Regular exercise training is a useful strategy to reduce inflammatory markers, but it is still unclear what type of training is better. Thus, this study compared the effects of 12-week of low-intensity resistance (Low-RT) and high-intensity interval aerobic training (High-IAT) on serum interleukin (IL)-6 levels and insulin resistance (IR) markers in obese and young men. Methods I...
متن کاملThe effect of high intensity interval training on telomere length and telomerase activity in non-athlete young men
Introduction: Telomeres are DNA portions that are located on the two ends of the chromosome. Telomeres play an important role in cellular life. Exercise is one of the factors that contributes to their control. The purpose of the present study was to investigate the effect of 8 weeks of high intensity interval training (HIIT) on telomere length and telomerase activity in non-athletic young men. ...
