The Correlational Study of the Vertical Jump Test and Wingate Cycle Test as a Method to Assess Anaerobic Power in Road Cyclists

Road Cycling is an important sport that uses anaerobic and aerobic metabolism and especially sprinter cyclists have higher anaerobic capacity. The assessment of anaerobic power in cyclists often involves the use of the vertical jump and Wingate cycle tests. The lack of research in the field of cycling-specific tests to assess anaerobic performance has led to the improvement of existing research. The objective of this research was to investigate the correlation between the vertical jump test and the Wingate anaerobic cycling tests, both of which are often used to assess anaerobic power in road cyclists. A correlation study was conducted on 15 athletes of the Turkish national road cycling team in the 14-16 age group (15.107 ± 0.717 (SD)). The sample of the study was determined by using the convenient sampling method. On the first day, anthropometric measurements and the vertical jump test were conducted. The Wingate cycle ergometer test, lasting for a duration of 30 seconds, was administered to the participants on the second day. The computer application was used to determine the 30-second peak and average anaerobic power during the test. The results acquired from the study revealed a statistically significant positive relationship between the vertical jump performance and the peak power production measured during the Wingate cycle test (r=0.321, p<0.05). The findings indicate that vertical jump tests may serve as suitable field measurements of anaerobic power for road cyclists, as an alternative to the laboratory-based Wingate anaerobic test.

VALIDITY AND RELIABILITY STUDY OF THE RUNNING-BASED ANAEROBIC SPRINT TEST FOR EVALUATING ANAEROBIC POWER PERFORMANCE AS COMPARED TO WINGATE TEST IN INDIAN MALE TRACK AND FIELD SPRINTERS

<p><strong>Aim</strong>: To investigate the criterion validity and relative and absolute reliability of the running-based anaerobic sprint test (RAST) in Indian male track and field sprinters. <strong>Material and Methods</strong>: Thirty five (n = 35) Indian male sprinters participating in 100m, 200 m and 400 m sprint racing randomly performed RAST and Wingate test as the criterion measure of anaerobic power with one trial each on two separate days. Data were analyzed using the Student’s paired <em>t</em>-test, Pearson’s linear correlation test, intra-class correlation coefficients and Bland and Altman’s plots. <strong>Results</strong>: Criterion validity was strong and positively significant for average power (<em>r </em>= 0.644, <em>p </em>< 0.000); however, the RAST significantly overestimated maximum and minimum anaerobic power compared to Wingate as revealed by paired t-test. The RAST showed good relative reliability for average power, ICC = 0.628 (0.373 - 0.795: 95% CI) and the higher internal consistency was found only for average anaerobic power value (α = 0.772). In the Bland-Altman analyses, linear regression analyses revealed that both means of differences and limits of agreement were found to be low in cases of average and minimum values of anaerobic power and fatigue index and the results were also not found to be statistically significant, resulting in good reliability. <strong>Conclusion</strong>: The RAST is a practicable field test to estimate levels of average anaerobic power of track and field sprinters. Coaches and trainers can use RAST for anaerobic power assessment that does not require the use of sophisticated and expensive equipment.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0935/a.php" alt="Hit counter" /></p>

A controlled clinical study of product PINOROX® (Pinus roxburghii bark extract) (PINOROX®) as dietary supplement for enhanced physical performance

Pinorox® is a standardized composition obtained from pine bark extract of Pinus roxburghii, rich source of natural polyphenols - Oligomeric Proanthocyanidins (OPCs) compounds that act as an antioxidant. Pinorox® has been expected to serve as potential natural supplement consumed to enhance the physical endurance in normal healthy or a sport person. Hence, double-blind, randomized, placebo-controlled study was conducted for time period of 90 days to validate the effect of Pinorox® over physical and athletic performances in normal healthy as well as sports subjects. 50 eligible subjects were selected through screening and distributed into placebo and Pinorox® groups. The subjects utilized in the present study i.e., healthy individual and athletes received one of either 200 mg of Pinorox® or experimental control (placebo) for 90 days. Each subject was evaluated for increase in physical or athletic performances by observing changes from baseline in rate of oxygen consumption VO2 max (endurance) compared to placebo at baseline, assessment of anaerobic power and rate of fatigue by using Wingate test at baseline, changes in assessment values using 1-RM test and muscle grip strength assessment using handheld dynamometer at baseline and during the interval of 90 days. The observations discussed in the present study shows that people consuming Pinorox® displayed significantly advanced performances during exercising or performing given sports activities. Improvement in the VO2 max values, anaerobic power, rate of fatigue, muscular performance and muscle grip strength was observed in test results and the study did not report any adverse effect. Overall, the study demonstrates that Pinorox® is a safe, fast acting and effective natural dietary or sport supplement for enhancing physical and athletic performances.

Comparison between seated medicine ball throw test and Wingate test for assessing upper body peak power in elite power sports players

Objectives: Upper limb explosive power is an important motor quality for sporting performance and indicates use of anaerobic energy systems. The Wingate Anaerobic Test (WAnT) has been considered to be a valid and reliable tool for the assessment of anaerobic power and functional performance of elite athletes. However, it is expensive and a lab based test and requires skilled manpower. The seated medicine ball throw test (SMBT) is inexpensive, easy to assess and since equipment required is minimal, it can be easily used as a field test. Hence, the purpose of the study was to determine if the SMBT method could be used as an alternative for WAnT test so that a reliable and inexpensive test is available for athlete monitoring and talent identification screening. Materials and Methods: Male elite athletes aged 18–30 years (n = 100), who were involved in national level competition of three sports discipline, namely, Boxing (n = 34), Wrestling Greco-Roman (GR) (n = 36), and Wrestling Freestyle (FS) (n = 30), were tested on crank-arm ergometer for WAnT and SMBT to measure an peak power or explosive power for the upper body. Results: SMBT test results were significantly positively correlated with upper body peak power measured by WAnT in all sportsmen (r = 0.55, P = 0.0002). One sample t-test results showed that the mean difference between SMBT and peak power is close to zero among Boxers (P = 0.13) and FS wrestlers (P = 0.89) and GR Wrestlers (P = 0.49). Overall, 97% pairs of SMBT and peak power were within the limits of agreement among all sportsmen, showing that results using both the tests were agreeable. Conclusion: This study suggests that SMBT tests could be used as an alternative field test to measure anaerobic power in Wrestlers, Boxers, and sports where the involvement of upper body muscles take place predominantly. In addition, the SMBT protocol used in this study provides an easy way for the coaches to assess the athletes on the field during talent identification and also to evaluate their training program.

Anaerobic Power Assessment in Athletes: Are Cycling and Vertical Jump Tests Interchangeable?

Regularly assessing anaerobic power is important for athletes from sports with an explosive strength component. Understanding the differences and overlap between different assessment methods might help coaches or smaller-scale testing facilities maximize financial and temporal resources. Therefore, this study investigated the degree to which cycling sprint and vertical jump tests are interchangeable for determining peak mechanical leg power output in strength-trained athletes. Professional skiers (n = 19) performed unloaded squat jumps (SJ) and other jump forms on a force plate and a six-second cycling sprint (6sCS) test on an ergometer on six occasions over two years. Along with cross-sectional correlations between cycling and jumping power, correlations between longitudinal percent changes and agreement between magnitude-based inferences about individual changes were assessed. Among the tested jump forms, SJ reflected 6sCS best. However, despite extremely large cross-sectional correlation coefficients (0.92) between 6sCS and SJ, and moderate (Pearson’s r = 0.32 for 6sCS with SJ over one-year time spans) to large (r = 0.68 over shorter time spans) correlation coefficients on percent changes, magnitude-based inferences agreed in only around 50% of cases. Thus, for making qualitative assessments about the development of anaerobic power over time in athletes, cycling sprint and squat jump tests are not interchangeable. Rather, we recommend employing the test form that best reflects athletes’ strength and conditioning training.

Performance and Health-Related Characteristics of Physically Active Males Using Marijuana

Lisano, 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 status: marijuana 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 acute effects of a multi-ingredient pre-workout supplement on resting energy expenditure and exercise performance in recreationally active females

BackgroundThe use of dietary supplements to improve performance is becoming increasingly popular among athletes and fitness enthusiasts. Unfortunately, there is a tremendous lack of research being done regarding female athletes and the use of sport supplements. The purpose of this study was to examine the acute effects of multi-ingredient pre-workout supplement (MIPS) ingestion on resting metabolism and exercise performance in recreationally-active females.MethodsFifteen recreationally-active females participated in a randomized, double-blind, placebo controlled study. Subjects completed baseline, and two experimental testing sessions in a cross-over design fashion. Experimental testing included assessment of resting energy expenditure (REE), heart rate, and blood pressure following the ingestion of a MIPS or placebo. Subjects also completed a repetition to failure test for the back squat (BS) and bench press (BP) at 85% of their 5-repetition maximum followed by the assessment of anaerobic power using a counter-movement vertical jump test and a sprint test on a force-treadmill. Subjective measurements of energy, focus, and fatigue were also assessed using a 5-point Likert scale. Separate repeated measures analysis of variance (ANOVA) were used to assess differences in REE, cardiovascular responses, and subjective markers between conditions. Performance data were analyzed using paired Student’s T-tests.ResultsA significant main effect for condition was observed for REE (p = 0.021) and diastolic blood pressure (p = 0.011) following ingestion of the MIPS. The supplement condition resulted in a greater number of BP repetitions to failure and total work completed during treadmill test (p = 0.039) compared to placebo (p = 0.037). A significant condition x time interaction for focus was observed with the supplement treatment exhibiting improved focus at 80-min post ingestion (p = 0.046).ConclusionsConsumption of a MIPS increased resting metabolism following a single dose accompanied by an increase in diastolic blood pressure. Furthermore, acute MIPS ingestion improved upper body muscular endurance and anaerobic capacity while improving feelings of focus following high-intensity exercise in recreationally active females.

Assessment of anaerobic power to verify VO2max attainment

Across various populations, verification testing is used to confirm VO(2)max attainment and has repeatedly shown similar VO(2)max values to those obtained from incremental exercise. Yet, many individuals show meaningful differences in VO(2)max between protocols, and an explanation for this is unknown. The aim of the study was to elucidate this phenomenon in 30 men and women of similar age, fitness, and physical activity using assessment of anaerobic power. On day 1, they completed the Wingate test, and returned at least 48 h later to complete incremental cycle ergometry followed by a verification protocol. During exercise, ventilation, pulmonary gas exchange data, and heart rate (HR) were continuously measured. Mean VO(2)max was similar (P > 0.05) between protocols (42.05 +/- 5.88 ml kg(-1) per min versus 42.03 +/- 5.75 ml kg(-1) per min, respectively), although seven subjects (23%) revealed a VO(2)max that was not 'verified' by the supramaximal protocol. Indices of power output and gas exchange data were similar (P > 0.05) between subjects who revealed a 'true' VO(2)max compared to those who did not, although peak and mean power was consistently higher in persons whose VO(2)max was not 'verified.' A previously established HRmax criterion for verification testing was not met in 17% of subjects. Additional study is merited to identify alternate determinants of VO(2)max, such as muscle activation via assessment of motor unit recruitment, and to investigate utility of verification testing to confirm VO(2)max attainment in elite athletes and the elderly.

Comparison of Two Anaerobic Water Polo-Specific Tests With the Wingate Test

The purpose of the current study was to compare 2 water polo-specific tests-the 14 x 25-m swims (SWIM) and the 30-second crossbar jumps (30CJ)-with a laboratory-based test of anaerobic power, the Wingate Anaerobic Test (WAnT). Thirteen elite women's water polo players (mean +/- SD: age 22.0 +/- 4.4 years, height 168.7 +/- 7.9 cm, body mass 65.9 +/- 6.1 kg, body fat 23.6 +/- 3.5 %, maximum oxygen uptake 51.4 +/- 4.5 mlxkgxmin) participated in the study. The SWIM involved 14 repeated "all-out" sprints every 30 seconds. Swimming time was recorded, and sprint velocity, mean velocity (Vmean), and the gradient of the linear regression equation (GRADIENT) were calculated. The 30CJ involved repeated in-water water polo jumps and touching the goal crossbar with both hands. The number of touches in 30 seconds was recorded. Additionally, the subjects completed a 30-second WAnT, and mean power (Mp) and fatigue index (FI) were calculated. Kendall tau (tau) rank correlation was used to examine for correlation between ranks. Significance level was set at p <or= 0.05. No significant correlation was found between any of the measures of the WAnT and the 2 sport-specific tests. It was suggested that the WAnT may not be an appropriate evaluation tool for anaerobic power assessment of water polo players, stressing the importance of sport-specific tests.

Prediction of Anaerobic Power Values from an Abbreviated WAnT Protocol

The traditional 30-second Wingate anaerobic test (WAnT) is a widely used anaerobic power assessment protocol. An abbreviated protocol has been shown to decrease the mild to severe physical discomfort often associated with the WAnT. Therefore, the purpose of this study was to determine whether a 20-second WAnT protocol could be used to accurately predict power values of a standard 30-second WAnT. In 96 college females, anaerobic power variables were assessed using a standard 30-second WAnT protocol. Maximum power values as well as instantaneous power at 10, 15, and 20 seconds were recorded. Based on these results, stepwise regression analysis was performed to determine the accuracy with which mean power, minimum power, 30-second power, and percentage of fatigue for a standard 30-second WAnT could be predicted from values obtained during the first 20 seconds of testing. Mean power values showed the highest level of predictability (R2 = 0.99) from the 20-second values. Minimum power, 30-second power, and percentage of fatigue also showed high levels of predictability (R2 = 0.91, 0.84, and 0.84, respectively) using only values obtained during the first 20 seconds of the protocol. An abbreviated (20-second) WAnT protocol appears to effectively predict results of a standard 30-second WAnT in college-age females, allowing for comparison of data to published norms. A shortened test may allow for a decrease in unwanted side effects associated with the traditional WAnT protocol.

Reliability of Upper Extremity Anaerobic Power Assessment in Persons With Tetraplegia

Background/Objective: Reliable assessment of upper extremity anaerobic power in persons with cervical spinal cord injury (SCI) may indicate the ability to successfully and safely perform many daily activities.Purpose: To examine test-retest reliability of upper extremity Wingate anaerobic testing (WAnT) in persons with motor/sensory complete tetraplegia.Methods: Forty-five persons with cervical-level SCI (15 individuals each at C5, C6, and C7 levels of injury) performed 2-arm WAnT bouts, with 2 to 4 days between bouts. Subjects performed the WAnT seated in their wheelchairs using a tabletop-mounted Monarch 834E ergometer. Resistance loads were applied relative to injury level, with 1%, 2%, and 3% of body mass applied to subjects with C5, C6, and C7 level injuries, respectively. All subjects were directed to crank the ergometer at maximal velocity for a30-second period. Values of peak power (P peak) and mean power (P mean) were determined using an SMI OptoSensor 2000 system. P peak and P mean were compared between trials and between groups using 2-way analyses of variance for repeated measures. Coefficients of determination (r2) were calculated between trials.Results: There were no significant differences in P peak or P mean detected between the 2 trials of WAnT in the C5, C6, or C7 groups. Regression analyses revealed statistically significant associations between bouts for Pmean and P peak in each of the 3 groups (P < 0.05).Conclusions: Upper extremity WAnT is reliable for upper extremity anaerobic power assessment in persons with cervical SCI at or below the C5 level.

Reliability of Upper Extremity Wingate Anaerobic Testing in Persons With Complete Tetraplegia

0793 Accurate and reliable assessment of anaerobic power production provides important information regarding the ability to perform tasks requiring repeated bursts of muscular force. Arm Wingate anaerobic testing (WAnT), a 30-sec sprint on an arm cycle ergometer, has been found to be a reliable measure of upper extremity muscular power in persons without physical disabilities and in persons with paraplegia. PURPOSE: To examine test-retest reliability of arm WAnT performance in persons with complete cervical level spinal cord injury (SCI). METHODS: Forty five persons with motor complete SCI at levels C5-C7, performed two trials of WAnT. The study sample included three groups of 15 persons each at the C5, C6, and C7 levels of injury. Testing was performed using a Monark 834 E leg ergometer (Monark, Varberg, Sweden) attached to a table, foot pedals replaced with cushioned handgrips. The resistance load used during WAnT was 1%, 2%, and 3% of body mass for subjects in the C5, C6, and C7 groups, respectively. Power output during arm WAnT was determined by the SMI OptoSensor 2000 (Sports Medicine Industries, Inc., St. Cloud, MN, USA) hardware and software package. Measurements from testing included peak power (Ppk) and mean power (Pmn), which were compared between trials and between groups using two-way ANOVAs for repeated measures. Coefficients of determination (r2) were calculated between trials for Ppk and Pmn in each group. RESULTS: Results indicated significant differences between groups (C7>C6>C5) for both Ppk and Pmn, with no significant differences detected between trials for Ppk or Pmn. The r2 values between trials, for the three groups, ranged from 0.91 to .97 for Ppk and from .93 to .98 for Pmn. CONCLUSION: Upper extremity WAnT testing is a reliable outcome measure for assessment of anaerobic muscular power in persons with SCI tetraplegia.

Diagnostics of anaerobic power and capacity

Testing procedures for the assessment of anaerobic energy metabolism during muscular work have not yet gained the relevance of tests assessing maximal aerobic power. The diagnosis of aerobic power allows one, through the choice of an adequate testing protocol, to design a test that mainly measures the power of aerobic metabolism by means of indicators like VO2max and lactate. With regard to tests for the assessment of anaerobic power and capacity, however, alactic, lactic, and oxidative components of energy expenditure as a whole cannot be differentiated by means of simple parameters (e.g., lactate and time until exhaustion). By means of computer simulations of energy metabolism for supramaximal loads with durations until exhaustion of about 10 s and 60 s as well as the isolated variation of the concentration of muscle phosphocreatine, the maximal rate of lactate production, and the maximal aerobic power (VO2max), the influence of the single components on energy metabolism as a whole is presented in a semi-quantitative way. Subsequent testing procedures for the measurement of alactic and lactic power as well as alactic and lactic capacity are presented. Finally critical-power method and method for the determination of maximal accumulated O2 deficit are described in greater detail, because both methods are widely discussed in contemporary international literature.

RELIABILITY TESTING OF THE WINGATE ANAEROBIC POWER TEST IN COMPETITIVE MALE CYCLISTS

PURPOSE The purpose of this investigation was to determine the relibility and power output differences of two resistances for the Wingate anaerobic test using an electronically braked cycle ergometer (Lode, Groningen, The Netherlands). We tested seven competitive (Category II-IV) male adult cyclists (mean ± S.E., age 36. ± 3.2y, ht 182.6 ± 1.6cm, wt 77.4 ± 3.1kg, body fat 12.0 ± 1.1%, VO2max 4.3 ± 0.8L• min−1). METHODS Inclusion criteria consisted of a VO2max of at least 4.0 L• min−1. Subjects performed one Wingate test per day at a pre-randomized resistance of 0.80 kg/kgbw or 0.95 kg/kgbw. A total of 4 trials were performed, 2 trials per resistance, each trial was separated by 48 hours (Trials 1 & 3 = 0.80 kg/kgbw; Trials 2 & 4 = 0.95 kg/kgbw). RESULTS A one-way ANOVA and follow-up post-hoc analysis found differences between trials 1 & 3 and trials 2 & 4 for absolute peak power, relative peak power, and relative mean power (p < 0.05). No differences were observed for absolute mean power. Relative peak power was 16.2±0.3 W/kg and 17.8±1.7 W/kg for the 0.80 kg/kgbw and 0.95 kg/kgbw resistances, respectively (p < 0.05), which appear to be considerably higher than what is reported in the literature. A Pearsons Correlation demonstrated that the two resistances were found to be statistically identical in repeatability between trials 1 & 3 and 2 & 4 (r2 = 0.921, p = 0.003 and r2 = 0.929, p = 0.003, respectively). CONCLUSIONS The results indicate that power output is significantly greater using a higher resistance with Wingate anaerobic power testing (absolute peak power, relative peak power, and relative mean power) in competitive male cyclists. Therefore, for a more accurate assessment of anaerobic power in competitive male cyclists a resistance of 0.95 kg/kgbw should be utilized.

Evaluation of a New Anaerobic Power Testing System

The purpose of this study was to evaluate the reliability of a new anaerobic athletic performance system. This system is proposed to assess vertical jump height, anaerobic power through repetitive jumping, and reaction to both an auditory and visual stimulus. One hundred twenty-three subjects (92 men and 31 women; mean ± SD: age, 20.5 ± 2.1 years; body weight, 83.1 ± 20.4 kg; height, 176.0 ± 9.2 cm) volunteered to participate. To assess reliability of the new testing device, subjects were tested on 3 separate occasions (T1, T2, and T3). At least 72 hours but not more than 1 week separated each laboratory visit. During each testing session subjects performed a countermovement jump (CMJ), a 30 consecutive jumps anaerobic power test (30JT), and reaction to both an auditory and visual stimulus. Results showed no differences between T1, T2, and T3 in either CMJ height or 30JT assessments. However, reaction to an audible or visual stimulus significantly improved during each testing session. Intraclass reliability of the CMJ and the 30JT was greater than 0.96 across the 3 trials. Pearson correlation coefficients of r > 0.90 were seen for the CMJ and 30JT, indicating a high test-retest reliability. The test-retest reliability for the reaction tests were lower (r ranging from 0.72 to 0.83). A Bland-Altman plot showed limited agreement between methods of vertical jump height assessment. Results indicate that this new testing device shows high reliability to assess both CMJ height and anaerobic power. In addition, anaerobic power assessment in a jump test provides a specific measure of anaerobic power for many sports incorporating similar performance patterns.
