RSI = Reactive Strength Index (JH/CT); JH = Jump Height; CT = Contact Time. GAT = Gastrocnemius–Achilles Tendon unit; PT = Patellar Tendon; QT = Quadriceps Tendon; RF = Rectus Femoris muscle. r = Pearson’s correlation coefficient. p = p value. The alpha level was set to 0.0236 after the Benjamini-Hochberg procedure. Significant values are in bold.
