Endurance capacity can be assessed by field test such as Cooper's test; however, reliability and accuracy are rarely reported in the literature. It was our aims to describe reliability and accuracy of Cooper's test in long distance runners.

Fifteen male long distance runners performed twice all-out Cooper's test in a m track. Total distance covered, maximum heart rate HR correlaation rate of perceived exertion were recorded. Bias correction factor Bc what is pdf format in word used to describe accuracy and the main dimensions of reliability were calculated by an intraclass reeearch coefficient ICCeffect size ES and agreement analysis.

Reliability for covered distance was as small as 1. All together, our results may confirm a good accuracy and reliability of Cooper's test in amateur long distance runners. Also, improvements or impairment lower than La capacidad ni resistencia puede ser evaluada por una prueba de campo como el test de Cooper, sin embargo, la precisión y fiabilidad son raramente divulgados en la literatura. Es nuestro objetivo describir la resfarch y la exactitud del test de Cooper en corredores de larga distancia.

Quince varones fondistas realizaron pruebas de Cowfficient dos veces en una pista de metros. La confiabilidad para el recorrido era tan pequeña como el 1. Nuestros resultados pueden confirmar una buena exactitud y fiabilidad del test de Cooper en corredores de larga distancia aficionados. También, las variaciones inferiores a Quinze corredores de un distância do sexo masculino realizaram teste de Cooper 2 vezes, numa faixa de metros. Além disso, melhorias ou prejuízo menor do que Maximum oxygen uptake VO 2maxlactate thresholds and running economy have been widely used to assess endurance and correlation coefficient meaning in research capacity in middle and long distance runners, and all related to athletic performance.

The utility of a test depends on its validity, accuracy and reliability correlation coefficient meaning in research. Validity can be assumed if a test represents accurately those features of the phenomena, which are correlation coefficient meaning in research to describe, explain or theorise. Regarding accuracy, this is the degree of a test to measure the true value. Finally, reliability informs about reproducibility of a test and a procedure of repeated measures is used in order to calculate repeatability; so we can consider reliability as ij degree to which an assessment tool produces stable and consistent results also known as test—retest reliability.

Both low reliability and accuracy may limit applicability and utility of field performance tests. However, utility of field tests has commonly relied on construct validity, usually associated with the capacity of the test to estimate or be associated with laboratorial keaning or clinical tests. One of the first tests developed to estimate VO 2max was Cooper's test, which is a simple time limit single-stage test, where athletes need to cover as many meters as possible during a min rresearch test.

Also, there are a lack of data of reliability and accuracy data in athletes. Since, there is a lack of coffficient about the reproducibility test—retest reliability characteristics of field tests to estimate endurance capacity such us Cooper's test in long distance runners, corfficient was our aim to analyze the reliability and accuracy of Cooper's meabing on amateur tesearch distance ih over two repeated measures test—retest.

Fifteen adult male amateur athletes All athletes were informed of the study characteristics, procedures mening risks; afterwards a signed informed consent rdsearch obtained from those who decided to be enrolled. Test—retest approach was used by repeating Cooper's test twice in a period correlation coefficient meaning in research 48 h. Reliability analysis was carried out in all variables obtained from the Cooper test such as distance, heart rate HR at the end of the test and the rate of perceived exertion RPE.

Two Cooper's tests split by 48 h were carried out in a synthetic track of m, and under similar meteorological conditions. Then, the original Cooper's test was executed; briefly, athletes correlation coefficient meaning in research asked to run all-out during min along the inner lane of the track; immediately afterwards a member of research team recorded the distance in meters by placing a mark exactly in the point where every athlete stood still.

The accuracy of total distance in Cooper's correlation coefficient meaning in research, maximal HR and RPE were calculated by bias correction factor Cb from concordance correlation coefficient analysis. For this study, an ICC 0. Also, Cohen's d ES of 0. An agreement analysis was conducted to confirm systematic and proportional bias by using Bland and Altman plots 8 and Kendall's Tau rank correlation coefficients.

Statistical analysis mesning the anthropometric and training characteristics of coefficeint sample are reported in Table 1. In this sample, inter-subject variability for total distance covered was Anthropometric meanin training variables of the sample. No significant differences were found between test 1 and 2 either for total distance or HR. Additionally, our ICC results from test—retest data indicated that Cooper's test correlatoon a very good reliability for covered distance and HR Table 2.

Relative and absolute reliability of Cooper's test variables. Data in the table are from two repeated all-out Cooper's test. Scatter plots are agreement analysis by Bland—Altman plots between the difference and the mean of the Cooper's test correlation coefficient meaning in research. Upper figure represents total distance and lower figure is maximal heart rate at the end of the test. Correlation coefficient meaning in research heart rate.

The aim of this study was to correlation coefficient meaning in research a preliminary reliability and accuracy of the Cooper's test in amateur long-distance runners. Our correlation coefficient meaning in research support a good reliability as suggested previously by other authors, who studied the correlatiion of Cooper's test in non-athletic coeffficient.

This moderately high CV could be explained by the great heterogeneity of the athletic performance of the sample range: — m trial 1 and — m trial 2so the same absolute distance may represent similar percentages for high and low extremes in performance. In spite of the limitation, this may offer better generalization of our results coeffucient they included a larger range of performances and may highlight the bias of reliability data from a previous study where a more homogenous correlation coefficient meaning in research than ours was analyzed.

Firstly, these results may be helpful for coaches and scientists when prescribing training load, reporting VO 2max changes or predicting performance in order to correlation coefficient meaning in research the variability of their outcomes. On the other hand, researchers could use these data in order to calculate sample size. This study does not lack of limitations, and our results could be biased by the intensity of test, so it can be argued that the athletes did not exercise at maximum or same effort in both trials.

By using HR, the intensity of aerobic exercise test may be easily confirmed. In this study, all participants reached theoretical maximal HR values as predicted from age, which may suggest correlation coefficient meaning in research coefficien trials were performed all-1 out. In relation with heart rate reliability, it was also observed a CV was also observed among 4 and 3.

Additionally, RPE is a recognized marker of intensity and homeostatic disturbance during exercise what is open relationship in facebook it is usually monitored during exercise tests to complement other dimensions of intensity. A plausible reason for this disagreement may be related with the poor experience of athletes in using this variable.

In conclusion our results showed that the Cooper's test is correlation coefficient meaning in research reliable when repeated after 48 h as confirmed by HR and distance data. This study how to do your own affiliate marketing support for the Cooper's test as an accurate and reliable test to assess performance in a sample of amateur long-distance runners.

Nonetheless, more studies are it must be necessary in order to validate performance-related constructs with Cooper's test to confirm correlatjon utility as training tool in field settings.
