Effects of a Combined Training Model on Pitching Velocity in Youth Baseball Players

Abstract

The objective of this study was to investigate the impact of a Combined Training Model, defined by strength-power exercises and plyometric activities, on the throwing efficiency of 15 male youth pitchers (aged 15 to 16) from the Caribe Club in Montería, Colombia. Methodologically, the study was based on an empirical-analytical paradigm, was quantitative, and used a quasi-experimental pretest-posttest design with a single group. The actual intervention was carried out over an eight-week period based on Tudor Bompa's periodization approach and was divided equally into Anatomical Adaptation (weeks 1 to 4) and Power Conversion (weeks 5 to 8). The dependent variable, ball exit velocity (mph), was measured using a JUGS Sport Gun radar. Once the data were collected, descriptive and inferential statistical analysis was performed using the paired-samples t-test with a significance level of p < 0.05. The authors conclude that their findings indicate it is possible to increase the kinematic performance of pitchers by a statistically significant amount, suggesting that the systematic coupling of baseline strength with the stretch-shortening cycle promotes optimal kinematic energy transfer. In summary, the tested model demonstrates that it is a highly successful and safe methodology for increasing pitching velocity in players during training phases and that it dispelled regional empirical myths about overload training in the same area.
