The interval model training has been more recommended to promote aerobic adaptations due to recovery period that enables the execution of elevated intensity and as consequence, higher workload in relation to continuous training. However, the physiological and aerobic capacity adaptations in interval training with identical workload to continuous are still uncertain. The purpose was to characterize the effects of chronic and acute biomarkers adaptations and aerobic capacity in interval and continuous protocols with equivalent load. Fifty Wistar rats were divided in three groups: Continuous training (GTC), interval training (GTI) and control (CG). The running training lasted 8 weeks (wk) and was based at Anaerobic Threshold (AT) velocity. GTI showed glycogen super-compensation (mg/100 mg) 48 h after training session in relation to CG and GTC (GTI red gastrocnemius (RG)=1.41±0.16; GTI white gastrocnemius (WG)=1.78±0.20; GTI soleus (S)=0.26±0.01; GTI liver (L)=2.72±0.36; GTC RG=0.42±0.17; GTC WG=0.54±0.22; GTC S=0.100±0.01; GTC L=1.12±0.24; CG RG=0.32±0.05; CG WG=0.65±0.17; CG S=0.14±0.01; CG L=2.28±0.33). The volume performed by GTI was higher than GTC. The aerobic capacity reduced 11 % after experimental period in GTC when compared to GTI, but this change was insignificant (19.6±5.4 m/min; 17.7±2.5 m/min, effect size = 0.59). Free fatty acids and glucose concentration did not show statistical differences among the groups. Corticosterone concentration increased in acute condition for GTI and GTC. Testosterone concentration reduced 71 % in GTC immediately after the exercise in comparison to CG. The GTI allowed positive adaptations when compared to GTC in relation to: glycogen super-compensation, training volume performed and anabolic condition. However, the GTI not improved the aerobic performance.

This study was aimed to: (1) investigate the effects of physiological functions of sprint interval training (SIT) on the aerobic capacity of elite badminton players; and (2) explore the potential mechanisms of oxygen uptake, transport and recovery within the process. Thirty-two elite badminton players volunteered to participate and were randomly divided into experimental (Male-SIT and Female-SIT group) and control groups (Male-CON and Female-CON) within each gender. During a total of eight weeks, SIT group performed three times of SIT training per week, including two power bike trainings and one multi-ball training, while the CON group undertook two Fartlek runs and one regular multi-ball training. The distance of YO-YO IR2 test (which evaluates player’s ability to recover between high intensity intermittent exercises) for Male-SIT and Female-SIT groups increased from 1083.0 ± 205.8 m to 1217.5 ± 190.5 m, and from 725 ± 132.9 m to 840 ± 126.5 m (p < 0.05), respectively, which were significantly higher than both CON groups (p < 0.05). For the Male-SIT group, the ventilatory anaerobic threshold and ventilatory anaerobic threshold in percentage of VO2max significantly increased from 3088.4 ± 450.9 mL/min to 3665.3 ± 263.5 mL/min (p < 0.05),and from 74 ± 10% to 85 ± 3% (p < 0.05) after the intervention, and the increases were significantly higher than the Male-CON group (p < 0.05); for the Female-SIT group, the ventilatory anaerobic threshold and ventilatory anaerobic threshold in percentage of VO2max were significantly elevated from 1940.1 ± 112.8 mL/min to 2176.9 ± 78.6 mL/min, and from 75 ± 4% to 82 ± 4% (p < 0.05) after the intervention, which also were significantly higher than those of the Female-CON group (p < 0.05). Finally, the lactate clearance rate was raised from 13 ± 3% to 21 ± 4% (p < 0.05) and from 21 ± 5% to 27 ± 4% for both Male-SIT and Female-SIT groups when compared to the pre-test, and this increase was significantly higher than the control groups (p < 0.05). As a training method, SIT could substantially improve maximum aerobic capacity and aerobic recovery ability by improving the oxygen uptake and delivery, thus enhancing their rapid repeated sprinting ability.

Abstract Introduction. So far there have been few studies on the effect of interval training with active recovery aimed at increasing aerobic power on the physical capacity of long-distance runners. Unlike standard interval training, this particular type of interval training does not include passive rest periods but combines high-intensity training with low-intensity recovery periods. The aims of the study were to determine the effect of aerobic power training implemented in the form of interval training with active recovery on the physical capacity of amateur long-distance runners as well as to compare their results against those of a group of runners who trained in a traditional manner and only performed continuous training. Material and methods. The study involved 12 recreational male long-distance runners, who were randomly divided into two groups, consisting of 6 persons each. Control group C performed continuous training 3 times a week (for 90 minutes, with approximately 65-85% VO2max). Experimental group E participated in one training session similar to the one implemented in group C and additionally performed interval training with active recovery twice a week. The interval training included a 20-minute warm-up and repeated running sprints of maximum intensity lasting 3 minutes (800-1,000 m). Between sprints, there was a 12-minute bout of running with an intensity of approximately 60-70% VO2max. The time of each repetition was measured, and the first one was treated as a benchmark in a given training unit. If the duration of a subsequent repetition was 5% shorter than that of the initial repetition, the subjects underwent a 15-minute cool-down period. A progressive treadmill test was carried out before and after the 7-week training period. The results were analysed using non-parametric statistical tests. Results. VO2max increased significantly both in group E (p < 0.05; d = 0.86) and C (p < 0.05; d = 0.71), and there was an improvement in effort economy at submaximal intensity. Although the differences were not significant, a much greater change in the post-exercise concentrations of lactate and H+ ions was found in group E. Conclusions. The study showed that interval training with active recovery increased VO2max in amateur runners with higher initial physical capacity and stimulated adaptation to metabolic acidosis more than continuous training.

High Intensity Interval

Although moderate-intensity continuous training (MICT) has been the traditional model for aerobic exercise training for over four decades, a growing body of literature has demonstrated equal if not greater improvement in aerobic capacity and similar beneficial effects on body composition, glucose metabolism, blood pressure, and quality of life from high-intensity interval training (HIIT). An advantage of HIIT over MICT is the shorter time required to perform the same amount of energy expenditure. The current brief review summarizes the effects of HIIT on peak aerobic capacity and cardiovascular risk factors in healthy adults and those with various cardiovascular diseases, including coronary artery disease, chronic heart failure, and post heart transplantation.

AbstractThere is no clear evidence that vitamin D effectively improves physical capacity in high-level athletes. The aim of this study was to confirm that vitamin D supplementation of soccer players during eight-week high-intensity training would have a significant effect on their aerobic capacity. The subjects were divided into two groups: the experimental one that was supplemented with vitamin D (SG, n = 20), and the placebo group (PG, n = 16), not supplemented with vitamin D. All the players were subjected to the same soccer training described as High-Intensity Interval Training (HIIT). The data of the vitamin D level, PWC170, lactate threshold (LT) were collected just before and after the intervention. A significant increase in vitamin D concentration (119%) was observed in the supplemented group, while the non-supplemented group showed a decrease of 8.4%. The studied subjects improved VO2max results by 20% in the SG, and by 13% in the PG. The improvement in velocity at the LT was similar in both groups. Results of this study show that vitamin D can have a positive, though moderate, effect on aerobic performance in players subjected to high-intensity training in the form of small-sided games for 8 weeks.

Background: Metabolic syndrome (MetS) is a clustering of complications that are associated with an increased risk of cardiovascular diseases. Numerous studies have reported a positive effect of exercise on lipid profile and liver enzymes. Objectives: The purpose of this study was to investigate the effect of eight weeks of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) with sodium alginate supplementation (S) on the levels of liver enzymes and lipid profile in men with MetS. Methods: This is a semi-experimental study. Forty young men with MetS volunteered and were randomly divided into five groups: HIIT+S (n = 8), HIIT (n = 8), MICT+S (n = 8), MICT (n = 8) and control (C; n = 8). Blood samples were collected after 12 hours of fasting, 48 hours before the first, and after the last training session to measure liver enzymes and lipid profile. ANOVA, t-test, and Tukey's post hoc test were employed for data analysis using SPSS version 21. Results: The results showed that after eight weeks of intervention, significant improvements were observed in lipid profile and liver enzymes in the four experimental groups. These improvements were more significant in the HIIT+S than in other groups (P < 0.05). Also, the MetS Z score decreased significantly in all experimental groups, and this decrease was significantly higher in the HIIT + S than other groups (P < 0.05). Conclusions: Generally, the results showed that HIIT and MICT led to an overall improvement in men with MetS. However, combining sodium alginate supplementation triggers these improvements.

AbstractPurpose. The aim of this study was to investigate the influence of 8-week-long interval training (targeting glycolytic capacity) on selected markers of physical fitness in amateur long-distance runners. Methods. The study involved 17 amateur long-distance runners randomly divided into an experimental (n = 8) and control (n = 9) group. The control group performed three or four continuous training sessions per week whereas the experimental group performed two interval running training sessions and one continuous running training session. A graded treadmill exercise test and the 12-min Cooper test were performed pre- and post-training. Results. O2max and the rate of recovery increased in the experimental group. Relative oxygen uptake, minute ventilation, and heart rate speed decreased in low- (6 km/h) and medium-intensity (12 km/h) running. Conclusions. Both training modalities showed similar results. However, the significant differences in training volume (4-8 min interval training vs. 40-150 min continuous training) indicates that the modalities targeting glycolytic capacity may be more efficient for amateur runners prepare for long-distance events.

Introduction: Amyloid plaques in the brain increase with age. Thus, the present study aimed to evaluate the effect of continuous and interval training on Amyloid β 42 (Aβ42) and Malondialdehyde (MDA) levels in hippocampus of elderly rats. Methods: The present study was experimental one with two experimental groups and one control group. Thirty old male Wistar rats (18 weeks-old) divided into 3 groups, including interval training, continuous training, and control. Continuous training was performed for 8 weeks with 65 to 70% VO2max and interval training was performed for 8 weeks with 5-8 repetitions of 2 minutes of working with 80-100% VO2max and 2 minutes active rest with 50% of VO2max for 8 weeks. Hippocampal samples were extracted 48 hours after the last training session to measure protein levels of Aβ42 and MDA. One-way ANOVA and Tukey post hoc test was used for data analysis. Results: Hippocampus Aβ42 levels in continuous training groups were significantly lower than the control group (P=0.001). In addition, Aβ42 levels in hippocampus of interval training groups were significantly lower than the control group (P=0.001). However, no significant differences were found in Aβ42 levels between continuous and interval training groups (p=0.502). MDA levels in continuous training groups were significantly lower than the control group (P=0.016). In addition, MDA levels in interval training groups were significantly lower than the control group (P=0.046) But no significant differences were found in hippocampal MDA protein levels between continuous and interval training groups (p=866). Conclusion: Continuous and interval training through decreasing oxidative stress, decrease Aβ42 levels in the hippocampus of the elderly rat, thus probably continuous and interval training can prevent neurodegenerative disease caused by aging through modulating oxidative stress and Aβ42.

Objectives The present study compares the effect of high-intensity interval training (HIIT; 18 min) and moderate-intensity continuous training (MIT; 1 h) on reverse cholesterol transport (RCT) elements in obese subjects. Methods Thirty adult male rats were induced high-fat diet (HFD) for 12 weeks. After four weeks, the rats were randomly divided into three groups while simultaneously continuing the HFD for the remaining eight weeks. Group specificities were HFD–control, HFD–MIT and HFD–HIIT. The rats were sacrificed 48 h after the last training session and the samples were collected. Analysis of variance and Pearson’s correlation test were used for the statistical analyses (significance level: p ≤ 0.05). Results The results showed that both HIIT and MIT improved heart ABCA1, ABCG1, ABCG4, ABCG5, ABCG8, LXR-α and PPARγ gene expression as well as plasma Apo A1, LCAT, lipids and lipoproteins ( p ≤ 0.05). Moreover, higher cardiac ABCA1, ABCG1, ABCG4, ABCG5, ABCG8 and PPARγ expression and plasma high-density lipoprotein cholesterol ( p ≤ 0.05) concentrations were found in the HFD–HIIT group compared with the HFD–MIT group. Conclusion HIIT may have more cardioprotective effects than MIT against atherosclerosis, along with saving time, as supported by the changes observed in the main factors involved in the RCT process.
