Agreement of variables derived from the countermovement jump between the My Jump Lab and JumPo 2 applications.
Background: The countermovement jump (CMJ) is widely used to assess neuromuscular performance in various contexts. For evaluation purposes, apps such as My Jump Lab and JumPo 2 emerge as accessible alternatives to force platforms, offering practicality and low cost. However, to date, no study has di...

For evaluation purposes, apps such as My Jump Lab and JumPo 2 emerge as accessible alternatives to force platforms, offering practicality and low cost. However, to date, no study has directly investigated the agreement between these two apps in measuring CMJ variables. Objective: To verify the agreement of CMJ-derived variables between the My Jump Lab and JumPo 2 apps. Methods: Fifty young adult women performed three maximal CMJ while being simultaneously filmed with a smartphone camera. Each jump was analyzed using the My Jump Lab and JumPo 2 apps, considering the following parameters jump height (cm), flight time (ms), force (N), and power (W). To compare the applications, the t-test, Pearson correlation, intraclass correlation coefficient (ICC), Bland-Altman plots and effect sizes (Cohen's d) were used, with a significance level of p < 0.05. Results: The difference between the applications was low (p > 0.05), with insignificant effect sizes (d < 0.20), in addition to presenting a high correlation for all observed parameters (jump height: Δ = 0.19 ± 1.04 cm, d = 0.17, ICC = 0.985, r = 0.973; flight time: Δ = 0.52 ± 12.97 ms, d = 0.04, ICC = 0.983, r = 0.967; force: Δ = 23.16 ± 150.72 N, d = 0.15, ICC = 0.825, r = 0.705; power: Δ = 21.55 ± 133.93 W, d = 0.16, ICC = 0.918, r = 0.850. Conclusion: The smartphone applications My Jump Lab and JumPo 2 have high agreement for analyzing measures derived from the CMJ, especially for jump height and flight time. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
