Background: Research on the effects of interval training on lipid profile and hematological indices is limited. Objectives: Therefore, the purpose of this study was to determine the effects of eight weeks of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on aerobic performance, body composition, lipid profile, and hematological indices in overweight adolescents. Methods: Thirty overweight boys (13 - 16 years) participated in this study and were randomly divided into three groups, including the control (n = 10), HIIT (n = 10), and MICT (n = 10) groups. HIIT training (4 × 4-minute) was performed with an intensity of 95 - 85% of maximum heart rate, and MICT training (35-minute) was performed with an intensity of 70 - 60% of maximum heart rate, three sessions per week for eight weeks. Beep test and ELISA technique were used to measure aerobic performance, lipid profile, and hematological indices, respectively. The two-way repeated-measures ANOVA was used to determine the differences with a confidence interval of 95% (α = 0.05). Results: The results showed that except for the variables of glucose, triglyceride (TG), and low-density lipoprotein (LDL), all other variables in the HIIT group had a significant change compared to the pre-test (P < 0.05). Also, the results showed that there was a significant difference between the HIIT and control groups in fat percentage, VO2Max, high-density lipoprotein (HDL), iron, and hemoglobin value (P < 0.05). Conclusions: The results suggest that HIIT training can be as effective as continuous strategy training to reduce the risk factors associated with cardiovascular disease in overweight adolescents.

Anaerobic threshold is the level of oxygen consumption where lactate concentration in blood increasing rapidly and systemic. One of exercises which increase anaerobic threshold is high intensity interval training (HIIT), with training load over anaerobic threshold in a short time and interspersed with active recovery. Another form is steady state training (SST), with training load approaching anaerobic threshold constantly. The purpose of this study to determine differences in the effectiveness of HIIT and SST among students member of short distance running athletic extracurricular groups in Denpasar. This study is pre test and post test experimental group design for 6 weeks and three times a week. Samples included 24 people divided into 2 groups. Group 1 HIIT with the training load of 95% maximum heart rate and Group 2 SST with the training load 80% of maximum heart rate. Measurement of anaerobic threshold by determining Heart Rate Deflection Point (HRDP) according to the Conconi track protocol. The results of the study in both groups obtained subjects 12-16 years old, male, body weight 50-65 kg, height 160-178 cm, and IMT from 16.33 to 22.27 kg / m2. Mean of anaerobic threshold before HIIT training 178.17 ± 2.368 x/minute, while after HIIT increased to 197.83 ± 3.460 x/minute. Mean of anaerobic threshold before SST 177.17 ± 1.586 x/minute, while after SST increased to 185.25 ± 1.288 x/minute. Test of different mean of anaerobic threshold pretest within Group 1 and Group 2 showed that p=0,237 (p>0,05). Test of different mean of increasing anaerobic threshold before and after training in Group 1 and Group 2 using Independent t-Test data test post two groups showed that p = 0.01 (p <0.05). Its concluded HIIT increase anaerobic threshold more than SST among students member of short distance running athletic extracurricular groups in Denpasar. Suggestions for this study are expected coaches able to provide proper training and monitoring methods HRDP evaluation in improving the achievement of athletes.

Purpose: Atherosclerosis is a complex multifactorial disease whose first steps can be initiated from childhood. Therefore, we examined the effects of 2 training models on salusins levels, inflammatory markers, and lipid profile in boys with overweight/obesity. Method: Forty-five boys with overweight/obesity with the mean age of 11.06 (1.0) years were randomly divided into three groups of 15: a high-intensity interval training (HIIT) group (100%–110% of maximum aerobic speed); an aerobic training group (40%–70% of heart rate reserve); and a control group. The intervention included 3 sessions per week for 12 weeks. Results: Findings showed significant improvements in serum levels of salusins, salusins ratio, interleukin-6 (IL-6), and total cholesterol (TC) in both training groups (P < .001). Also, the serum levels of C-reactive protein (CRP), triglycerides (TG), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), atherogenic index of plasma (AIP), and cholesterol index improved significantly (P < .01). Except for the TG, HIIT caused higher improvements than aerobic training (P < .001 for salusin-α, salusins ratio, IL-6, CRP, TC, HDL, AIP, and cholesterol index; and P < .01 for salusin-β and LDL). Conclusion: The present study shows that HIIT has more positive effects than aerobic exercise on the atherosclerotic and inflammatory factors, as well as lipid profile variables in children with overweight/obesity.

Introduction: Obesity and overweight in adolescents and adults are associated with chronic diseases. The objective of this study was to determine the effect of high-intensity interval training and pre-meal water intake on the lipid profile of overweight and obese students. Methods: This was a pre-post experimental study. Twenty-seven overweight and obese students (mean BMI 26.0±3.1 kg/m2 and mean age 19.7±0.7 years) were divided randomly into three groups. The first group (n=9; BMI=26.6±3.6 kg/m2) received Plain Water Intake (PWI) intervention, whereby students received three bottles of plain water (600 mL) per mealtime (total 1.8 L/ day) and consumed ad libitum 30 to 45 minutes before mealtime (breakfast, lunch, and dinner). The second group (n=9; BMI=25.9±2.4 kg/m2) received High-Intensity Interval Training (HIIT) intervention and underwent three exercise sessions per week (18 minutes/day; 70–85% of HRmax) that was introduced through a video recording. The last group (n=9; BMI= 25.7±3.4 kg/m2) received a combination of PWI+HIIT intervention. Nutritional status, nutrient intake, and lipid profile [total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C)] were assessed before and after the interventions. Data were analysed using paired sample t-test and Analysis of Variance (ANOVA). Results: The PWI group showed a significant increase in HDL-C, while the HIIT group showed a significant reduction in TC (p<0.05). On the other hand, the PWI+HIIT group showed significant improvements in lipid profile (TC, TG and HDL-C) (p<0.05). Conclusion: A combination of PWI+HIIT intervention may be effective in improving lipid profile.

Physically inactive adults are prevalent worldwide. This study compared the effects of short-term high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) on heart rate variability (HRV) in physically inactive adults as a preliminary study. Thirteen physically inactive male adults (27.5 ± 3.80 years) were randomly assigned to HIIT (N = 7) or MICT (N = 6). The HIIT program consisted of 20 min of interval training with cycling to rest ratio of 10/50 s at ≥90% HRpeak, while the MICT program consisted of 40 min of continuous cycling at 60–75% HRpeak. Both groups completed eight sessions of training within two weeks. Time and frequency domains of HRV were measured for 20 min with Actiwave-Cardio monitor (CamNtech, UK). The number of R-R interval and inter-beat interval (IBI) were significantly improved (p < 0.05) in both HIIT and MICT programs following eight sessions of training. A significant interaction effect for group by time was found in the lnLF/HF ratio (p < 0.05) where it was only improved in the HIIT group from pre- to post-test. The HIIT program is superior to MICT in improving HRV in physically inactive adults. The HIIT program can be applied as a time-efficient program for improving cardiac-autoregulation.

Abstract Purpose The present study was conducted to compare the effects of low volume of high intensity interval training (LVHIIT) and high volume of high intensity interval training (HVHIIT) on heart rate variability (HRV) as a primary outcome measure, and on maximum oxygen consumption (VO2max), body composition, and lower limb muscle strength as secondary outcome measures, in sedentary young women. Methods Thirty-six participants were recruited in this study. The LVHIIT group (n = 17) performed one 4-min bout of treadmill running at 85%–95% maximum heart rate (HRmax), followed by 3 min of recovery by running at 70% HRmax, three times per week for 6 weeks. The HVHIIT group (n = 15) performed four times 4-min bouts of treadmill running at 85%–95% HRmax, interspersed with 3-min of recovery by running at 70% HRmax, 3 times per week for 6 weeks. All criterion measures were measured before and after training in both the groups. Results Due to attrition of four cases, data of 32 participants was used for analysis. A significant increase in high frequency (HF) power (p < 0.001) and decrease in the ratio of low frequency to high frequency power (LF/HF) ratio (p < 0.001) in HRV parameters, was observed post-HVHIIT, whereas, these variables did not change significantly (HF: p = 0.92, LF/HF ratio: p = 0.52) in LVHIIT group. Nevertheless, both the interventions proved equally effective in improving aerobic capacity (VO2max), body composition, and muscle strength. Conclusion The study results suggest that both LVHIIT and HVHIIT are equally effective in improving VO2max, body composition, and muscle strength, in sedentary young women. However, HVHIIT induces parasympathetic dominance as well, as measured by HRV.
