Aim. The article deals with establishing the effect of the method for speed endurance enhancement in female track-and-field athletes from the Kola peninsula through blood lactate control at 11 mmol/l. Materials and methods. The study was conducted from November 2017 to April 2018. At the first stage, we created an experimental group of track-and-field athletes from sports school No 4 (Murmansk). All female athletes (middle-distance runners, n = 34) were 18–20 years old and possessed the first or the second adult category at the time of selection. 1 km test was conducted to establish speed endurance in participants. At the second stage, a 6-month experiment was conducted: all athletes had a 6-week interval training at a distance of 1 km with timekeeping, pulsometry, and blood count for establishing blood lactate immediately after each segment of the distance. At the third stage, a control 1 km test was conducted. The authors analyzed the results obtained using statistical methods (р ≤ 0.01). Results. It was established that the main methods for the development of speed endurance in female athletes are repetitive and interval methods. The main means of speed endurance enhancement are resistance running, running rhythm, and pursuit running. In the first two months of interval training, a significant increase in speed endurance, pulse values, and lactate (no more than 11 mmol/l) was registered. Stagnation of results was registered during the 4th, 5th, 7th, 11th, and 12th weeks of training. Conclusion. The data obtained can be used as a part of special physical preparation in female track-and-field athletes aged 18–20 years from Murmansk and Murmansk region.

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.

Background One of the most popular high-intensity interval exercises is the called “Tabata Protocol”. However, most investigations have limitations in describing the work intensity, and this fact appears to be due to the protocol unfeasibility. Furthermore, the physiological demands and energetic contribution during this kind of exercise remain unclear. Methods Eight physically active students (21.8 ± 3.7 years) and eight well-trained cycling athletes (27.8 ± 6.4 years) were enrolled. In the first visit, we collected descriptive data and the peak power output (PPO). On the next three visits, in random order, participants performed interval training with the same time structure (effort:rest 20s:10s) but using different intensities (115%, 130%, and 170% of PPO). We collected the number of sprints, power output, oxygen consumption, blood lactate, and heart rate. Results The analysis of variance for multivariate test (number of sprints, power output, blood lactate, peak heart rate and percentage of maximal heart rate) showed significant differences between groups (F = 9.62; p = 0.001) and intensities (F = 384.05; p < 0.001), with no interactions (F = 0.94; p = 0.57). All three energetic contributions and intensities were different between protocols. The higher contribution was aerobic, followed by alactic and lactic. The aerobic contribution was higher at 115%PPO, while the alactic system showed higher contribution at 130%PPO. In conclusion, the aerobic system was predominant in the three exercise protocols, and we observed a higher contribution at lower intensities.

Background: There is individual responsiveness to exercise training as not all individuals experience increases in maximal oxygen uptake (VO2max), which does not benefit health status considering the association between VO2max and mortality. Approximately 50% of the training response is genetic, with the other 50% accounted for by variations in dietary intake, sleep, recovery, and the metabolic stress of training. This study examined if the blood lactate (BLa) response to high intensity interval training (HIIT) as well as habitual dietary intake and sleep duration are associated with the resultant change in VO2max (ΔVO2max). Methods: Fourteen individuals (age and VO2max = 27 ± 8 years and 38 ± 4 mL/kg/min, respectively) performed nine sessions of HIIT at 130% ventilatory threshold. BLa was measured during the first and last session of training. In addition, sleep duration and energy intake were assessed. Results: Data showed that VO2max increased with HIIT (p = 0.007). No associations occurred between ΔVO2max and BLa (r = 0.44, p = 0.10), energy intake (r = 0.38, p = 0.18), or sleep duration (r = 0.14, p = 0.62). However, there was a significant association between training heart rate (HR) and ΔVO2max (r = 0.62, p = 0.02). Conclusions: When HIIT is prescribed according to a metabolic threshold, energy intake, sleep status, and BLa do not predict ΔVO2max, yet the HR response to training is associated with the ΔVO2max.

Abstract BACKGROUND: Metformin has shown potential to improve metabolic efficiency in short-intense efforts, prolonged-continuous efforts and recovery after supramaximal effort (i.e., phosphocreatine resynthesis). Metformin administration may be beneficial for high-intensity interval training session. The aim of the present study was to investigate the acute metformin administration effects on performance, rating of perceived exertion (RPE), blood lactate, blood glucose and neuromuscular parameters related to a swimming series of high-intensity.METHODS: A double-blind, cross-over, randomized and placebo-controlled study was carried out. Seven healthy swimmers ingested MET (500mg) or placebo capsule on different days and performed a typical glycolytic session of high-intensity (i.e., lactate production objective). Bout time, RPE, neuromuscular parameters, blood lactate and glucose were analyzed. Cohen’s d analysis with inference based on magnitude was adopted (confidence interval set at 90%).RESULTS: There was an improvement in the performance of the second effort (72/28/0). Blood glucose during the series presented possible effects for decrease (96/3/1, 78/21/0, 93/6/1 after the 4th, 6th and 8th effort respectively) followed by a possible increase effect at the end of the series (1/6/93).Blood lactate showed a similar behavior of a possible decrease during the series (94/5/1, 60/40/0, 90/9/1 after the 4th, 6th and 8th effort respectively), followed by a possible increase effect at the end of the series (1/5/94). It was evidenced a possible increase effect on voluntary activation for lower limbs (91/8/1) without characterization of central and peripheral fatigue.CONCLUSION: Metformin alters physiological parameters during and after maximal intermittent efforts in swimming without enhancement on performance.

Purpose: To identify the anaerobic threshold through the lactate threshold determined by Dmax and rating of perceived exertion (RPE) threshold by Dmax and to evaluate the agreement and correlation between lactate threshold determined by Dmax and RPE threshold by Dmax during an incremental test performed on the treadmill in long-distance runners. Methods: A total of 16 long-distance runners volunteered to participate in the study. Participants performed 2 treadmill incremental tests for the collection of blood lactate concentrations and RPE separated by a 48-hour interval. The incremental test started at 8 km·h−1, increasing by 1.2 km·h−1 every third minute until exhaustion. During each stage of the incremental test, there were pauses of 30 seconds for the collection of blood lactate concentration and RPE. Results: No significant difference was found between methods lactate threshold determined by Dmax and RPE threshold by Dmax methods (P = .664). In addition, a strong correlation (r = .91) and agreement through Bland–Altman plot analysis were found. Conclusions: The study demonstrated that it is possible to predict anaerobic threshold from the OMNI-walk/run scale curve through a single incremental test on the treadmill. However, further studies are needed to evaluate the reproducibility and objectivity of the OMNI-walk/run scale for anaerobic threshold determination.
