Abstract Introduction: An overview of the literature on the subject of handball indicates that today’s top-level handball is dominated by sequences of short-duration (5 – 20 seconds) intensive anaerobic physical effort. Taking into account this data and the lack of scientific contribution describing the levels of the anaerobic capacity of top-level handball players, it seems essential to research this sphere of capacity in men’s Superleague teams. Aim: The objective of the study is to evaluate the relative mechanical work (J/kg), peak power (W/kg), peak power production time (s) and peak power sustainment time (s) in Wingate tests performed on players in various positions. Basic procedures: Research participants: 18 players in the Superleague handball team; average age of participants = 25.96±3.97 years old, average height = 192.76±7.21 cm, average body mass = 97.61±11.46 kg; average BMI = 25.84±1.92. The evaluation of anaerobic capacity was performed according to the 30-second Wingate test procedure, with the use of the Monark 824E cycle ergometer and the MCE v5.0 computer software. Results: The mean peak power of the research participants was 11.12±0.84 W/kg; mean work value – 254.56±16.92J/kg, mean peak power production time – 4.82±0.82s; peak power sustainment time – 2.98±1.04s; fatigue index – 25.82±3.64%. Conclusions: In the process of top-level handball training, it is necessary to pay more attention to the development of anaerobic endurance through the increased use of interval workload.

Purpose. The purpose of the study was to investigate the effects of high-intensity interval training on anaerobic capacity in taekwondo athletes. Materials and methods. The study recruited 20 male International Taekwondo Federation-style practitioners that were randomly divided into an experimental (n=10) and a control (n=10) group. The control group (C) executed a regular training protocol (five 90-min sessions per week) involving traditional TKD methods and techniques for 8 weeks. During the same timeframe, the experimental group (E) followed the same TKD training regime as group C except two of the five sessions were substituted with interval training-based TKD exercise involving 30 s of maximal kicking drills (round middle kick) separated by 90 s of rest. Anaerobic capacity and power were measured pre- and post-training by the 30-s Wingate cycle ergometer test. Results. Post-training values of peak power, total work output, and time of sustained peak power increased only in group E. Group E was also characterized by a significant post-training increase in minute ventilation (VE) and blood lactate (LA-). No significant changes were observed in group C. Connlusions. The inclusion of interval training-based exercise significantly enhanced anaerobic power and capacity in taekwondo practitioners.

Aerobic Interval Training

The effects of a 9-week aerobic interval training program on anaerobic intermittent performance were investigated. Intermittent work consisted of four repeat 30-sec maximal efforts on a cycle ergometer (Wingate test) with 3-min recovery intervals. Thirteen men trained 3 days a week on the cycle ergometer, completing 3-min work-to-rest intervals and progressing from 5 to 10 reps. Relative and absolute values of aerobic power increased significantly for the training group (p <.05). No significant change was observed for the control group (n = 11). The training group demonstrated significant increases in the four anaerobic variables of short-term peak power (SPP), short-term anaerobic capacity (SAC), intermediate-term peak power (IPP), and total work (TW), and across the four 30-sec maximal repeats for anaerobic performance (T1-T4) (p <.05). Greater percentages of increase occurred for IPP and TW, especially during Repeats 3 and 4. The control group only demonstrated a significant increase in SPP for Repeat 3. These data suggest that the type of interval training program used in the study increased aerobic power and also enhanced performance in repeated high intensity, short duration work. Key words: short-term peak power, intermediate-term peak power, total work

Anaerobic Test

Background/Aim. The Wingate anaerobic test is a valid and reliable method of measuring anaerobic capacity. The aim of this study was to determine whether other modified test can be used instead of the Wingate test. Methods. A group of 30 sedentary young men were first tested with a cycle ergometer (classic Wingate test), and then with a dynamometer during 30 s of 'all out' leg extension exercise (modified Wingate test; WAnTe) in order to test anaerobic capacity. Subsequent correlations between these tests were made. Results. Peak power, mean power on cycling ergometer in absolute and relative values were 463 ? 105 W, 316.7 ? 63.8 W, 5.68 ? 1.17 W/kg, 3.68 ? 0.78 W/kg, respectively. On a dynamometer absolute and relative values of maximal and mean load in kg and power in Watts were 136.54 ? 21.3 kg, 1.67 ? 0.26; 128.65 ? 19.93 kg, 1.57 ? 0.24 kg, 657 ? 125.87 W, and 8 ? 1.54 W/kg, respectively. There was no correlation between 5 s intervals of the classic Wingate test and WAnTe during the first, fourth and fifth intervals, but in the second (r = 0.49, p < 0.05), third (r = 0.38, p < 0.05) and last 5 s intervals (r = 0.39, p < 0.05), and also in peak power and mean power (r = 0.42, p < 0.05 and r = 0.45, p < 0.05 respectively), a significant positive correlation was detected. Conclusion. A modified Wingate test of leg extension on a dynamometer in sedentary young men shows a correlation with the classic Wingate test only in parameters of peak power, and mean power and the second, the third and the last 5 s intervals. Because of that it should only be used for orientation, whereas for precise measurements of anaerobic capacity the classic Wingate test should be used.

Background: Sprint interval training (SIT) performed on a cycle ergometer is a common mode of training and has become increasingly studied as an exercise intervention to improve a range of physical performance outcomes. Objectives: The primary objective was to synthesise findings from published research and through meta-analysis quantify the effect of SIT and potential moderators on physical performance outcomes with healthy adults. The secondary objective was to assess the methodological quality of included studies and the existence of small study effects. Methods: The review included studies from 2000 to 2020 based on the following criteria: 1) healthy participants 18 to 45 years; 2) minimum 2-week SIT intervention comprising “all out” sprints up to a maximum of 30 seconds on a cycle ergometer; 3) cohort or control group design; 4) pre-post intervention outcomes that could be categorised as aerobic (e.g. VO2max, incremental time); anaerobic (e.g. peak power, fatigue index); mixed aerobic/anaerobic (e.g. critical power test, peak power across repeated tests); or muscular force (e.g. maximal voluntary contraction, peak force). Methodological quality was assessed using a modified Downs and Black Checklist and a strategy based on the recommendations of the Grading of Recommendations Assessment Development and Evaluation working group. All meta-analyses were conducted within a Bayesian framework to facilitate probabilistic interpretations of mean standardised effect sizes obtained from both non-controlled and non-exercise-controlled data. Results: Fifty-five studies met the inclusion criteria, with 50% graded as moderate methodological quality and 42% graded as low methodological quality. Most studies (58%) comprised an intervention of 4 weeks or less, with the collective research featuring a wide range of training protocols. The primary meta-analysis was conducted on non-controlled effect sizes from 403 outcomes. The analysis identified a small to medium effect of improved physical performance with SIT (ES0.5 = 0.43 [95%CrI: 0.35 to 0.52]). Moderator analyses identified large differences among outcome types, with no evidence of an effect for muscular force outcomes (ES0.5 = 0.05 [95%CrI: -0.25 to 0.35]) and the largest effect estimated for anaerobic outcomes (ES0.5 = 0.57 [95%CrI: 0.33 to 0.86]). Additionally, moderation effects were identified for intervention duration, sprint length, and the number sprints performed per session, with larger effects obtained for greater values of each moderator. Many positive outliers were identified with additional evidence of extensive small study effects. Conclusion: This meta-analysis demonstrates that short-term SIT interventions are effective for developing small to moderate improvements in a range of physical performance outcomes across the aerobic to anaerobic spectrum. However, extensive small study effects, likely influenced by researchers analysing many outcomes, suggests potential overestimation of reported effects. It is recommended that future research analyse a smaller number of a priori selected outcomes and investigate models to progress SIT interventions for longer-term performance improvements.

Effects of recovery duration (2-3 s, 15 s, 30 s, 1 min, and 2 min) and time of day (9 a.m., 2 p.m., and 6 p.m.) on sprint performance were studied in 9 subjects using a cycle ergometer. The peak power (Ppeak) and the total work performed (W) were determined from changes in instantaneous power, taking into account the inertia of the flywheel. A decrease in Ppeak and W was observed after 15 s and 2-3 s recovery (p < 0.001). A logarithmic relationship (y = 3.92 ln x + 81.5; r = 0.82; n = 9) was found between Ppeak (%Ppeak of the first sprint) and the duration of the recovery (half-time = 14.3 s; SD = 7.6). Data indicated that there was no significant effect of time of day on Ppeak and W, regardless of the duration of recovery. The recovery processes occurred in a very short time and did not seem to be affected by biological rhythms. Key words: performance, diurnal variation, fatigue, ergometry, inertia

Eccentric Overload

This study aimed to evaluate the differences in power production between movement phases (i.e., concentric and eccentric) during the execution of resistance exercises with a flywheel device, differentiating between execution regimes (i.e., bilateral, unilateral dominant leg and unilateral non-dominant leg). Twenty young elite soccer players (U−17) performed two sets of six repetitions of the bilateral half-squat (inertia 0.025 kg·m−2) and the lateral-squat exercise (inertia 0.010 kg·m−2) on a flywheel device. During the testing sessions, mean and peak power in concentric (MPcon) and eccentric (MPecc) phases were recorded. The non-dominant leg showed higher values in all power variables measured, although substantial differences were only found in MPecc (ES = 0.40, likely) and PPcon (ES = 0.36, possibly). On the other hand, for both exercises, MPcon was higher than MPecc (ES = −0.57 to −0.31, possibly/likely greater), while only PPecc was higher than PPcon in the dominant lateral-squat (ES = 0.44, likely). These findings suggest that young soccer players have difficulty in reaching eccentric-overload during flywheel exercises, achieving it only with the dominant leg. Therefore, coaches should propose precise preventive programs based on flywheel devices, attending to the specific characteristics of each limb, as well as managing other variables to elicit eccentric-overload.

Purpose:Handball is a sport with high anaerobic demands in lower body as has been indicated by Wingate test (WT) performed with the legs, but there are no data available concerning power production during a WT performed with the arms in handball players (HndP). Therefore, the purpose of this study was to explore the arm anaerobic profile of HndP during a WT.Methods:Twenty-one elite HndP and 9 physical education students (CON), performed a 30-s arm WT. Power production and muscle oxy-genation were recorded.Results:Peak power (PP) as well as mean power (MP) was higher (P = .017 and 0.03, and ES = 1.00 and 0.86, respectively) for HndP (HndP PP: 7.6 ± 0.8 W·kg−1, CON PP: 6.7 ± 1.1 W·kg−1; HndP MP 5.3 ± 0.6 W·kg−1, CON MP 4.6 ± 0.9 W·kg−1) with no significant difference in fatigue index between the two groups. Muscle oxygen saturation (StO2) declined ~30% with exercise with no differences between groups. During recovery the HndP group had higher StO2 (P = .01, ES= 3.04), total hemoglobin and oxygenated hemoglobin compared with the CON group (P < .01 ES = 3.29 and 0.99, respectively). StO2 returned to resting values in 29.5 ± 2.3 s in HndP, whereas this variable did not recover after 2 min in CON.Conclusions:The arm anaerobic capacity of the HndP was “excellent,” significantly higher than that by the control group. Moreover, HndP exhibited faster recovery of StO2 compared with the control group. The greater power output and the faster muscle reoxygenation of arms in HndP can be attributed to specific training adaptations related to high performance in handball.
