Summary

Brief Summary We want to find out whether training with a weighted vest can help improve speed in U-14 baseball players. To do this, we will conduct a study with athletes like you, comparing performance before and after the training program.

How will we do it?

Participants will be randomly assigned to one of two groups:

Group 1: Will train with a weighted vest.

Group 2: Will train without a weighted vest.

Both groups will follow the same training program over 16 sessions. Running speed will be measured before and after the program to evaluate any improvements.

Who can participate?

Boys aged 13 to 14 years.

Members of the Tigres Baseball Club from San Pedro de Urabá.

Must have permission from a parent or legal guardian.

Who cannot participate?

Players with current injuries.

Those who regularly practice another sport.

Those who leave the club or are unable to complete the pre- and post-tests.

Is it safe? Yes! All procedures follow safety guidelines and will be conducted with informed consent from players and their families. Our goal is to enhance sports performance in a safe and effective way.

Conditions

  • Youth Baseball Speed, Sprint Training, Weighted Vest, Change of Direction

Interventions

BEHAVIORAL

Sprint Training With Weighted Vest

Participants performed a sprint training program wearing a weighted vest equal to approximately 10% of their body weight. The program lasted 6 weeks and included 16 sessions of linear and change-of-direction sprint drills. The goal was to examine whether the added external load improved running speed over 30 and 60 yards.

BEHAVIORAL

Sprint Training Without Weighted Vest

Participants completed the same sprint training program as the experimental group but without the use of a weighted vest. The intervention lasted 6 weeks and consisted of 16 sessions including sprint and agility exercises. This group served as the control condition to assess the effect of external resistance.
