Designing and sample - Making ofan Apparatus for Measuring of Vertical Jump and Anaerobic Power

Application ofthe Margaria - kalamen apparatus and test in Measuring of anaerobic power of athletes has some problems. Measuring ofanaerobic power of athletes with this device is not easy. so researchers and coaches need tests and devices that are valid, easy to use, cheap and applicable in all of sports fields. The purpose of this study was to design and sample-making of an apparatus (Ergo jurnpjʹ for measuring vertical jump and anaerobic powers. Two group of university students (n,~ 48, mean age of 22.08 years, weight of 61.56 kg and height of 174 cm and n,~68 mean age of24.58 years, weight of 72.0 1 kg and height of 175 ern) were selected randomly as subjects. The measurement tools ofthis study were a researcher-made apparatus (Ergojump), Margaria-Kalamen apparatus, a vertical jump device made in China and Sarjent protocols. The data were analyzed with SPSS software, Results: The research findings showed that, there were significant correlation coefficient (1""ʹD.75) between anaerobic power of Margaria-Kalarnen and researcher-made apparatus (Ergojump), and also a significant correlation coefficient (r ~ 0.77) exist between vertical jump of sarjent and Ergojump tests. Statistical analysis revealed that this apparatus and test had suitable validity and reliability in measuring vertical jump and anaerobic power. Conclusion: The findings of this research revealed that the Ergojump device and test is a valid and reliable substitution for Margarita-kalarnan test. Also in Measuring of vertical jump of athletes this devise is valid and can be a valid and reliable substitution for Sarjent and other vertical jump tests.
