Brief summary: Instrument-assisted soft tissue mobilization is a method that uses different devices to approach the myofascial system in variables such as joint mobility and muscle strength.

The objective of the study is to assess the effectiveness of the technique of soft tissue mobilization assisted by instruments in increasing the mobility of hip abduction and strength of the hip adductor musculature, in semi-professional rugby players federated in Spain of 18 at 32 years old Randomized, simple blind clinical study. 29 rugby players will be randomized to the two study groups: experimental (assisted soft tissue mobilization in the adductor leg muscles) and control (without intervention). The intervention will last 4 weeks, with 1 session per week, approximately 1 or 2 minutes each. The study variables will be hip abduction mobility (goniometry) and the strength of the hip adductor musculature (sphygmomanometry). A descriptive statistical analysis will be carried out calculating the main statistical characteristics. The distribution of normality will be calculated through an analysis of Saphiro Wilk. With the t-student test of repeated measures the differences will be calculated after the evaluations, and through an ANOVA of repeated measures the intra and intersubject effect will be calculated. The effect size will be calculated using the Cohen mean difference formula It is expected to observe an increase in hip abduction, as well as an increase in the strength of the adductor musculature of the hip.
