Drop set is a popular time-efficient resistance training method. This study aimed to compare the impact of drop-set (DS) training versus traditional resistance training (TRT) while ensuring equalized ...total training volume on the Wingate Anaerobic Test. Twenty-four sports science students were assigned to either DS (n=12) or TRT (n=12) protocols according to their 1 RM values, and they trained twice a week for 6 weeks.1 RM test was only conducted at the beginning of the study, while the Wingate anaerobic power test was administered at baseline and after the intervention period. The study demonstrated a significant main effect of time for peak power (p< 0.001), and a between-group interaction effect was observed for peak power (p< 0.05). The DS group exhibited slightly higher peak power values compared to TRT (p< 0.05, 15% increase for DS, 13% for TRT, ES: 0,50 and 0,36 respectively), while both groups displayed significantly increased values from pre to post-testing (p < 0.001). Based on our findings, it can be inferred that DS training leads to slightly greater enhancements in anaerobic power when compared to TRT. Additionally, the study confirmed that a 6-week (12 sessions in total) resistance training program utilizing a load of 70% of 1 RM was sufficient to enhance anaerobic performance in young active men.
The study purpose was to investigate the effect of complex training on aerobic and anaerobic power of amateur athletes.
Materials and methods. The study included 30 amateur athletes in soccer and ...hockey, which were equally divided into two groups, namely an Experimental group who underwent 6 weeks of complex training along with regular training in their sports and a Control Group who only performed their regular sports training. Anaerobic power was assessed by Running-based Anaerobic Sprint Test (RAST) and aerobic power (VO₂max) was assessed by 12-min Cooper run/walk test. The study used the Pre-test Post-test Randomized Group Design, and Paired t-test was used as the statistical technique for data analysis at a significance level of 0.05.
Results. At the end of six weeks, the Experimental group showed significant improvement in anaerobic power and VO₂max, while only VO₂max was improved in the Control group (p<0.05). No significant improvement was observed in anaerobic power for the Control group (p>0.06). Therefore, this shows that complex training has significant effect on anaerobic power, while it does not produce significant improvements in aerobic power.
Conclusions. Six weeks of complex training integrated with regular sports training can improve anaerobic power. Coaches and athletes, specifically in soccer and hockey, can implement the complex training program in their regular training.
Introduction: the objective of this study was to compare in young federated soccer players, the speed in a sprint of 30 meters in different ages. The times used in two phases were also compared (0 to ...10 meters and 10 to 30 meters) was analyzed according to age. Material and method: 505 male soccer players were measured with the 30-meter test, in an age range between 11,0 and 16,9 years. They were divided into 5 groups per chronological age. Anthropometric measurements (body weight and size) were analyzed. To measure the 30-meter test, three pairs of infrared synchronizations beam lamps (photocells) placed at; 0,0 m, 10,0m and 30,0 m from the starting line. Results: group 1 (11 years) traveled the distance of 30 meters in 5,48±0,36 s, group 2 (12 years) in 5,17±0,42 s, group 3 (13 years) in 4,94±0,44 s, group 4 (14 years) in 4,64±0,29 s, group 5 (15 years) in 4,56±0,28 s, and group 6 (16 years) in 4,42±0,22 s. Conclusion: The older youth, on average, traveled the distance of 30 meters in less time, although they only varied significantly between 11,5 and 14,5 years (p>0,01). During the segment o to 10m, the same trend was also observed, being significantly at all ages, except for 12,5 years (p>0,01).
The study aimed to investigate the anaerobic performance with laboratory and field tests in youth athletes in different sports. One-hundred four athletes between the ages of 10 and 16, minimum age of ...training of one year in different sports voluntarily participated in the study. Anthropometric measurements of participants were measured. Wingate Anaerobic Test (WAnT) using Monark cycle ergometer (Monark-Crescent AB, Sweden), Running-based Anaerobic Sprint Test (RAST), and pediatric RAST using photocell advice (Newtest 2000) were performed to determine anaerobic performance. Peak power (PP), average power (AP), minimum power (MP) and fatigue index (FI) were determined for each test. Absolute and relative power outputs, FI, and total exercise time (TED) values of WAnT, RAST, and PRAST were significantly different (p<0.01). The absolute peak, average and minimum power of PRAST were significantly higher than WAnT and RAST. According to test-retest results of WAnT, RAST, and PRAST, ICC 95% CI values have a high-reliability coefficient for all variables. It was found there is a positive correlation statistically between WAnT and RAST for all variables (p<0.01). Besides, there were also positive correlations statistically between WAnT-PRAST and RAST-PRAST excluding fatigue index (p<0.01). As a result of this study, it was determined WAnT, RAST, and PRAST have high reliability and are appropriate for child and adolescent athletes in that age group to evaluate anaerobic performance. Although tests have different motion properties, it was determined they have similar results when performed. High correlations between tests and variables support this determination.

This study examined the uniformity of adaptations in cardiorespiratory fitness and bio-motor abilities by analyzing individual responses to measures representing the mentioned qualities. Twenty-four ...male well-trained soccer players (Age = 26 ± 4 years; stature = 181 ± 3.8; Weight = 84 ± 6.1) were randomized to two groups performing short sprint interval training sSIT (3 sets of 10 × 4 s
sprints with 20 s of recovery between efforts and 3 min of rest intervals between sets) or a time-matched small-sided game SSG (3 sets of 3 v 3 efforts in a 20 × 15 m area with 3 min of relief in-between). Before and after the 6-week training period, aerobic fitness indices, cardiac hemodynamics, and anaerobic power were assessed through a graded exercise test utilizing a gas collection system, noninvasive impedance cardiography, and a lower-body Wingate test, respectively. Also, sport-specific bio-motor abilities were determined by measuring linear speed, change of direction, and jumping ability. Comparing inter-individual variability in the adaptive changes by analyzing residuals in individual adaptations indicated that sSIT induces more uniform changes in the first and second ventilatory threshold (VT
& VT
), stroke volume, and peak power output across team members than SSG. SSG also yielded lower proportions of responders in
, VT
, VT
, peak, and average power output compared to sSIT. Additionally, the coefficient of variation in mean group changes in measures of aerobic fitness and bio-motor abilities in response to sSIT were lower than in SSG. Short sprint interval training induces more homogenized adaptations in measures of cardiorespiratory fitness and anaerobic power than small-sided games across team members.
ABSTRACTLisano, JK, Smith, JD, Mathias, AB, Christensen, M, Smoak, P, Phillips, KT, Quinn, CJ, and Stewart, LK. Performance and health-related characteristics of physically active men using ...marijuana. J Strength Cond Res 33(6)1659–1669, 2019—The influence of chronic marijuana use on the performance and health of physically active individuals has yet to be fully elucidated. The purpose of this study was to explore pulmonary function, aerobic and anaerobic fitness, strength, serum testosterone, cortisol, C-reactive protein (CRP), Δ-9-tetrahydrocannabinol (THC), 11-nor-9-carboxy-Δ-9-tetrahydrocannabinol (THC-COOH), and 11-hydroxy-Δ-9-tetrahydrocannabinol (THC-OH) concentrations in a physically active population either using or not using marijuana. Healthy, physically active males (N = 24) were compared based on their marijuana-use statusmarijuana users (MU; n = 12) and nonusers (NU; n = 12). Statistical analysis (p = 0.05) revealed no difference between groups for age, body mass, body mass index, body fat, forced expiratory volume in 1 second percentage, VO2max, anaerobic power output, strength measures, testosterone, or cortisol concentrations. Although not statistically significant, MU showed a trend to fatigue to a greater percentage of absolute power output than NU from the beginning to the end of the Wingate Anaerobic Power Assessment (p = 0.08, effect size = 0.75). C-reactive protein in MU (1.76 ± 2.81 mg·L) and NU (0.86 ± 1.49 mg·L) was not significantly different (p = 0.60) but placed MU at moderate risk and NU at low risk for cardiovascular disease. Anaerobic fatigue was the only performance variable to show a trend for difference between groups. These results suggest that marijuana use in physically active males may not have significant effects on performance; however, it may be linked to elevated concentrations of CRP which place users at a higher risk for cardiovascular disease.
The purpose of this study was to examine the effects of short-term Rhodiola Rosea (Golden Root Extract (GRE)) supplementation on repeated Wingate performance. Eleven physically active college aged ...females were recruited for this study. In a within groups counterbalanced study design, participants were supplemented with either 1,500 mg/day of GRE or placebo (gluten-free cornstarch) for 3 days. Participants also took an additional 500 mg dose of corresponding treatment 30 minutes prior to testing of each trial. During each exercise trial, participants completed 3 × 15-second Wingate Anaerobic Tests (WAnTs) separated by 2-minute active recovery periods. Each exercise trial was separated by a 7 day washout period. Over the 3 × 15-second WAnTs, mean watts (p = 0.017, ES = 0.55), mean anaerobic capacity (p = 0.025, ES = 0.96), mean anaerobic power (p = 0.03, ES = 1.07), mean peak watts (p = 0.029,ES = 0.46), and mean total work (p = 0.017, ES = 0.49) were higher in the GRE treatment trial versus placebo. However, mean fatigue index (p = 0.094, ES = 0.39) was unaffected regardless of treatment. Our results show that GRE supplementation enhanced anaerobic exercise performance as measured through repeated WAnTs. GRE may possess ergogenic benefits and findings hold important implications for boosting anaerobic performance in repeated anaerobic bouts of exercise.
Introduction: Taekwondo is a combat sport, where high demands on aerobic and anaerobic metabolism are generated, with anaerobic power prevailing due to the short, high-intensity actions (1-5 seconds) ...that occur during combat, followed by long periods of does not fight with an average ratio between 1: 2 and 1: 7. Objective: To know the existing methods and protocols to assess anaerobic power in this sport and determine which of these is the most appropriate. Methodology: The specificity of the research required that the search for articles in databases such as: ScienceDirect, Taylor & Francis, Scopus and Ebsco be prioritized, using keywords such as: valuation, taekwondo and anaerobic power. Results: As a result of the exhaustive review, it was possible to identify various methods of assessing anaerobic power in taekwondo, mainly finding the Wingate Test, a method known as Gold Standard and used for years for such assessment and finding several relatively new specific Taekwondo tests. that have arisen from the need for a much more specific and objective assessment within Taekwondo, such as: FSKT (Fast Speed Kick Test), FSKTmult (Fast Speed Kick Test Mult), TAT (Taekwondo Anaerbic Test), TSAT (Taekwondo Specific Anaerobic Test), and TAIKT (Taekwondo Intermittent Kick Anaerobic Test). Conclusions: That the TAIKT, FSKT and FSKTmult tests are the most reliable and widely accessible tests for coaches and sports centers that need to assess the anaerobic power of taekwondo, facilitating the control of said capacity, as well as its monitoring in order to improve the performance of athletes and achieve high achievements.
