Summary

Increasing the speed of pitches is key in baseball performance. The interventions by means of the implement of weights are used to improve the strength and to strengthen the muscles of the shoulder. The objective of the study is to assess the effectiveness of an exercise protocol with weight implements in increasing the speed of throws and shoulder mobility in pitchers aged 18 to 40 years. Randomized pilot study. 12 pitchers will be randomized to the study groups: experimental (intervention with launches with weight implement) and control (without any intervention). The intervention will last 4 weeks, with 2 weekly sessions of 15 minutes each. The study variables will be the range of shoulder movement (goniometry) and the speed of the throws (speed radar). A descriptive statistical analysis will be performed calculating median and interquartile range. With the Shapiro-Wills test, the sample distribution will be calculated. If there is homogeneity, with the t-student test the changes will be calculated after the intervention in both groups. The intra and intersubject effect will be calculated with the ANOVA of repeated measures. The effect size will be obtained with Cohen's mean difference formula. It is expected to see improvement in the speed of the throws and in the range of shoulder movement.

Conditions

• Baseball Pitcher

Interventions

Type	Name	Description
OTHER	Weight implement	The technique will be done by making the same movement of the launch, but with the weight implement. The physiotherapist will be next to the pitcher, noting that there is no pain or discomfort when launching. The session will be held for 15min with 30 seconds of rest between each launch, until reaching 15 pitches. The sessions will be directed by a physiotherapist, in charge of supervising that the pitcher is correctly making the requested movement.
