Interesting study on pitching velocity:

A total of 420 pitchers were included, with a mean pitching velocity of 64 ± 10 mph.

After multivariate logistic regression analysis, the most important correlates with pitch velocity were age (P < .001; R2 = 0.658), height (P < .001; R2 = 0.076), separation of the hips and shoulders (P < .001; R2 = 0.027), and stride length (P < .001; R2 = 0.016); in combination, these 4 variables explained 78% of the variance in pitch velocity. Other findings:

- Each year of age was associated with a mean 1.5 mph increase in velocity
- Each inch in height, with 1.2 mph
- Separation of the hips and shoulders, with 2.6 mph
- A 10% increase in stride length, with 1.9 mph

Pitch velocity is most strongly correlated with age, height, separation of the hips and shoulders, and stride length.
