Abstract
Background: Running is one of the most popular sport activities around the world. Calf pain is common among runners and muscle injuries involving the gastrocnemius muscle are numerous. Triceps surae is very active during running and latent myofascial trigger points (MTrPs) are often found in strongly used muscle tissues. Therefore, it is relevant to investigate the prevalence of MTrPs in runners. Objective: 1. To observe the prevalence of latent myofascial trigger points (MTrPs) in gastrocnemius medialis of runners compare to non-runners. 2. To evaluate the muscle stiffness between latent MTrPs of runners and non-runners as well as between latent MTrPs and healthy muscle point. Design: an observational cross-sectional study. Method: Fifty-one healthy individuals were recruited (twenty-five runners and twenty-six non-runners). An investigator assessed both legs of all participants to evaluate the number of latent MTrPs in their gastrocnemius medialis before identifying the most painful MTrP. Another investigator measured the passive muscle stiffness (using MyotonPRO device) on the most painful MTrP site and on a healthy site. Results : A greater latent MTrPs prevalence in GM’s runners was found. Stiffness measured on MTrPs spots was higher by runners’ group. No difference has been observed between latent MTrP and healthy muscle site. Conclusion : This study is surely the starter to a new interest and understanding of MTrPs correlated to running practice by offering novel perspectives on injury prevention and performance management.
