Description:
The objective of this research is to devise a tool named Vertical Jump Measurement Portable (VJMP) with the purpose of facilitating practical and efficient measurements of vertical jumps, offering portability for use in diverse settings; concurrently, the research aims to evaluate the precision of VJMP in measuring vertical jumps. Employing research and development methodologies, this study involved the comparison of Vertical Jump Measurement Portable (VJMP) research products with traditional vertical jump measuring instruments. The research enlisted 42 participants who were athletes representing diverse sports disciplines. Data analysis included the application of the Mann-Whitney test to discern any statistically significant differences between the two vertical jump measuring instruments, with a threshold for significance set at p>0.05. The study outcomes revealed no statistically significant distinctions in the data obtained from two vertical jump measuring instruments, as indicated by a p-value of 0.754. This underscores the accuracy of VJMP in gauging vertical jumps. Furthermore, the tool exhibited notable efficiency, requiring a mere 41 seconds for the measurement of an individual. In conclusion, VJMP stands as an accurate and efficient instrument for assessing vertical jumps, thereby making it a viable choice for measurements across diverse sports and facilitating ease of use in practical field settings.
