THE DEVELOPMENT OF AN ANAEROBIC SPRINT RUNNING TEST UTILIZING A NONMOTORIZED TREADMILL
Journal of strength and conditioning research / National Strength & Conditioning Association, 2015
The purpose of this study was to determine the test-retest reliability of a newly developed anaerobic sprint running test (ASRT) on a nonmotorized treadmill (NMT). Twenty-six collegiate male athletes (21.2±2.1yr; 181.3±6.5cm; 79.0±9.3kg) completed three trials of a 25 s maximal effort sprint on a NMT against a workload set to 18% of their individual body mass. Anaerobic power was determined by relative peak power output (PP) and anaerobic capacity was determined by relative mean power output (MP) during the test. Blood lactate (BLa) responses and fatigue index (FI) were also determined. Test-retest reliability was assessed by intraclass correlation coefficients (ICCs) and coefficients of variation (CV%). Results indicated no significant difference between the three trials for PP (T1=29.95±6.51 W/Kg, T2=28.57±5.55 W/Kg, T3=29.47±5.94 W/Kg), MP (T1=20.97±3.64 W/Kg, T2=20.50±3.46 W/Kg, T3=21.17± 3.79 W/Kg), and FI (T1: 55±8%, T2: 51±8%, T3: 52±9%). Reliability between the three trials ...

To determine the statistical relationships among different consolidated performance tests (Yo-Yo, jump, sprint and agility), and the Powersprint™ device, an isotonic equipment, usually used to increase the muscular strength of athletes, used here as performance test. One hundred individuals were involved in the tests (16 females and 84 males). Ninety-five subjects were practicing different field sports, whereas 3 female and 2 male subjects were inactive. Gender, height and body mass were recorded. Participants completed the following tests: Squat Jump, Counter Movement Jump, 10 m sprint, 15 m sprint, Change of Direction, Yo-Yo Intermittent Recovery Test level 1 and PowerSprint 3.0™. Results of this experiment highlighted that PowerSprint 3.0™ is positively and significantly correlated with Squat Jump, Counter Movement Jump, 10 m sprint, 15 m sprint, Change of Direction, Yo-Yo Intermittent Recovery Test level 1. Additionally, the principal component analysis, as expected, was able to neatly differentiates between male, female and inactive subjects. The selected tests appeared particularly effective in giving information about athlete performances in soccer. Performances measured with the PowerSprint 3.0™ positively and significantly correlated with jumps, COD, sprint and YYIR1 tests. This is an indication of the possible use of this light, inexpensive and portable instrument for measuring athlete performances and checking the effectiveness of training programs.
Determination of Anaerobic Capacity - Reliability and Validity of Sprint Running Tests
Exercise Science, 2020
PURPOSE: A number of physiological diagnostics were developed. However, the timeline-related diagnostics of maximal anaerobic glycolytic capacity remain unclear. The objective of this study was to evaluate the reliability and validity of a sprint running test to assess the anaerobic capacity.METHODS: The study was divided into three parts. Sixty-one male (24±4 years, 181.0±4.3 cm; 78.5±5.9 kg) and twelve female (25±3 years, 167.0±0.6 cm, 60.4±5.7 kg) sports students participated in this study. Twenty-five subjects (13 males, 24±2 years, 181.0±0.5 cm, 78.5±5.9 kg; 12 females, 25±3 years, 167.0±0.6 cm, 60.4±5.7 kg) performed incremental step tests at running track and several linear sprints on a running track (LSRT) with different time durations (8, 10, 12, and 14 seconds)(part I) on different days. Twenty-five male subjects (24±3 years, 180.7±6.7 cm, 84.6±8.8 kg) conducted a 10 or 12 second sprint running on a non-motorized treadmill (NMT)(part II). In part III, twenty-three male sub...

Anaerobic capacity is an important performance variable for soccer athletes to compete at higher levels of competition. The purpose of this study was to develop a sports-specific anaerobic capacity test for soccer players that could be administered on commercial treadmills found in most exercise facilities. The Wingate Anaerobic test (WAnT) is the most common test for anaerobic capacity, however it is a cycle ergometer test, which is not sports-specific to running type athletes. The Anaerobic Speed Test (AST) is an anaerobic capacity test on a treadmill, however the testing protocol (20% incline) cannot be done on commercial treadmills because they have a maximum incline setting of 15%. The modified Anaerobic Speed Test (mAST) protocol (15% incline, 244 meter/min) was developed through the use of an ACSM metabolic equation to predict energy expenditure equivalent to that of the AST. 15 subjects playing soccer at the NCAA Division II level participated in this study. Subjects participated in three testing days, one AST trial and two mAST trials all done on separate occasions. Total run time in seconds was recorded for each trial. Mean AST run times (60.5±10.6) had a significantly strong, positive correlation (p<0.001) with mean Trial 1 mAST run times (71.9±9.5). iii Mean Trial 1 mAST run times (71.9±9.5) had a significantly strong, positive correlation (p<0.001) with mean Trial 2 mAST run times (75.7±10.2). These findings suggest that the mAST is a valid and reliable measure of anaerobic capacity that is sports-specific to running-type athletes and can be administered on commercial treadmills.
The validity of Running Anaerobic Sprint Test to assess anaerobic power in young soccer players
Isokinetics and Exercise Science, 2018
BACKGROUND: Studies have shown that Running Anaerobic Sprint Test (RAST) is population specific. OBJECTIVE: To investigate the validity of RAST in assessing the anaerobic power of young soccer players. METHODS: Thirty-one volunteer young amateur soccer players underwent a standardized WAnT test and a RAST test in random order. Peak power (PP), average power (AP), minimum power (MP), fatigue index (FI), blood lactate (LA), heart rate (HR) and ratings of perceived exertion (RPE) were determined during the tests. RESULTS: No significant differences were found between RAST-PP and WAnT-PP. RAST-AP and RAST-FI were significantly lower than that of WAnT whereas, RAST-MP was significantly higher than WAnT-MP. RAST-LAafter was significantly lower than WAnT-LAafter; however, mean and peak RAST-HR were significantly higher than WAnT. RPE responses were found to be similar between the tests. PP, AP and MP from the two tests were significantly correlated. The standard errors of the estimates values for PP, AP and MP were ± 78.5 W, ± 44.4 W and ± 38.7 W, respectively. Peak and mean HRs from two tests were significantly correlated. No significant association was present between RAST-LA and RAST-RPE, and WAnT-LA and WAnT-RPE, respectively. CONCLUSIONS: Although recruiting different physiological and metabolic processes, RAST may be used in place of WAnT to assess the anaerobic characteristics of young soccer players.

The intent of this study was to evaluate relative and absolute reliability of the 20-s anaerobic test (WAnT20) versus the WAnT30 and to verify how far the various indices of the 30-s Wingate anaerobic test (WAnT30) could be predicted from the WAnT20 data in male athletes. The participants were Exercise Science majors (age: 21.5±1.6 yrs, stature: 0.183±0.08 m, body mass: 81.2±10.9 kg) who participated regularly in team sports. In Phase I, 41 participants performed duplicate WAnT20 and WAnT30 tests to assess reliability. In Phase II, 31 participants performed one trial each of the WAnT20 and WAnT30 to determine the ability of the WAnT20 to predict components of the WAnT30. In Phase III, 31 participants were used to cross-validate the prediction equations developed in Phase II. Respective intra-class correlation coefficients (ICC) for peak power output (PPO) (ICC = 0.98 and 0.95) and mean power output (MPO) (ICC 0.98 and 0.90) did not differ significantly between WAnT20 and WAnT30. ICC...
The Anaerobic Power Assessment in CrossFit ® Athletes: An Agreement Study
Article, 2021
Anaerobic power and capacity are considered determinants of performance and are usually assessed in athletes as a part of their physical capacities' evaluation along the season. For that purpose, many field tests have been created. The main objective of this study was to analyze the agreement between four field tests and a laboratory test. Nineteen CrossFit ® (CF) athletes were recruited for this study (28.63 ± 6.62 years) who had been practicing CF for at least one year. Tests performed were: (1) Anaerobic Squat Test at 60% of bodyweight (AST60); (2) Anaerobic Squat Test at 70% of bodyweight (AST70); (3) Repeated Jump Test (RJT); (4) Assault Bike Test (ABT); and (5) Wingate Anaerobic Test on a cycle ergometer (WG). All tests consisted of 30 s of max effort. The differences among methods were tested using a repeated-measures analysis of variance (ANOVA) and effect size. Agreement between methods was performed using Bland-Altman analysis. Analysis of agreement showed systematic bias in all field test PP values, which varied between-110.05 (AST60PP-WGPP) and 463.58 (ABTPP-WGPP), and a significant proportional error in ABTPP by rank correlation (p < 0.001). Repeated-measures ANOVA showed significant differences among PP values (F(1.76,31.59) = 130.61, p = < 0.001). In conclusion, since to our knowledge, this is the first study to analyze the agreement between various methods to estimate anaerobic power in CF athletes. Apart from ABT, all tests showed good agreement and can be used interchangeably in CF athletes. Our results suggest that AST and RJT are good alternatives for measuring the anaerobic power in CF athletes when access to a laboratory is not possible.

The validity of the Running-based Anaerobic Sprint Test (RAST) was investigated to evaluate the anaerobic power performance in comparison to Wingate test in cycling athletes. Ten mountain-bike male cyclists (28.0±7.3 years) randomly performed Wingate Test and RAST with two trials each. After several anthropometric measurements, peak power (PP), mean power (MP) and fatigue index (FI) for RAST and Wingate Test were analyzed using Student's paired t-test, Pearson's linear correlation test (r) and Bland and Altman's plots. Results showed that, with the exception of FI (33.8±4.6% vs. 37.8±7.9%; r=0.172), significant differences were detected between the Wingate and RAST tests with regard to PP and MP. Although there was a strong correlation for PP and MP, or rather, 0.831 and 0.714 respectively, agreement of analysis between Wingate and RAST protocols was low. The above suggested that RAST was not appropriate to evaluate the performance of anaerobic power by Wingate test in c...
