Validity and Reliability of a Mobile App to Measure Vertical Jumps in Older Women

Résumé

The use of technology to approximate science to practice has been receiving attention, especially related to low-cost and portable devices. Thus, the present study aimed to investigate the validity and reproducibility of the Jumpo® application to measure vertical jump performance in older adults. 52 older women were invited to the survey. The evaluation consisted of the simultaneous application of countermovement and squat jumps through the contact mat and the application (Jumpo®). The results showed excellent correlation and inter-instrument agreement for the countermovement jump (ICC = 0.97; p <0.001; R2 = 0.0057) and squat jump (ICC = 0.95; p <0.001; R2 = 0.0006). The analysis intra-rater (ICC = 0.98, p <0.001), (ICC = 0.94, p <0.001) showed high values of reproducibility. As for inter-rater, they presented high reproducibility for countermovement jump and squat jump (ICC = 0.92, p <0.001), respectively (ICC = 0.94, p <0.001). Therefore, it is concluded that the Jumpo® application is a reliable tool for verifying maximum height in vertical jumps for the older adult population
