Background: The isometric mid-thigh pull test (IMTP) is commonly used in sports performance assessment, but it remains underutilized among combat sports athletes. Aims: to evaluate whether Pan-American medalists (PM) showed differences when compared with other athletes (NM) when performing the IMTP. Methods: a total of 72 Karate [n=35 (♀12)] and Taekwondo [n=37 (♀15)] athletes were measured (22.4±3.7 yrs.; 67.4±11.5 Kg; 1.7±0.1 m; 22.1±2.8 kg/m2). From the total, 32 athletes were PM of their specific combat sport (♀11). All participants performed the IMTP 60-90 days before the competition. The following variables were measured: a) Impulse Net at 50; 100; 150 and 200 ms (N*s); b) absolute (N) and relative peak force (PF; N/Kg) and; c) Rating of force development (RFD) at 50; 100; 150 and 200 ms (N/s). Results: PM showed a better performance on absolute (2,398.5±623.1 vs. 2,096.2±559.3 N; p=0.034) and relative PF (34.6±5.0 vs. 31.2±5.1 N/Kg; p=0.006); RFD at 150 (5,273.4±2,670.8 vs. 3,963.4±1,904.2 N/s; p=0.0018) and 200ms (4,870.3±2,184.6 vs. 4,022.1±1,574.8 N/s; p=0.05). Relative PF (Τ=0.249; p=0.011) and RDF at 150 ms (Τ=0.208; p=0.033) showed a positive and significative correlation with the competition result. Conclusion: PM showed a high PF and RFD at 150 and 200 ms. Furthermore, the competition result was correlated with relative PF and RDF at 150 ms. Based on our findings, we recommend that coaches incorporate the IMTP into their evaluation routine for striking athletes.
