*Significant group differences: Running km/week (p < 0.01): Hrec vs. Hrun and Trun (p < 0.01), and Trec vs. Hrun and Trun (p > 0.01); VISA-A (p < 0.01): Hrec vs. Trun and Trec (p < 0.01), and Hrun vs. Trun and Trec (p < 0.01); tendon thickness (p < 0.01): Hrec vs. Trun and Trec (p < 0.01), and Hrun vs. Trun (p = 0.04) and Trec (p = 0.02); CL (constant load) velocity (p < 0.01): Hrec vs. Trun (p < 0.01), Trun vs. Trec (p < 0.01).
