About

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.

Experimental group

Experimental group

Description:

Each session will last 15 minutes, taking place for 2 days a week, over a period of 4 weeks. The intervention will take place at the beginning of the training session. Prior to training, each pitcher will perform his normal warm-up routine, notifying the investigator when he feels ready to perform the training. The intervention through weight implements will consist in the application of the protocol described by Fleising et al. The objective of the application of the technique is to produce an increase in the speed of the throws.

Treatment:

Other: Weight implement

Control group

No Intervention group

Description:

Athletes included in the control group will conduct their training and activities on a daily basis
