Why Pitchers Should Bench Press

Upon the creation of my log, I found that someone had stated that they did not use the bench press for pitching, and I have seen some posts of people debating it. So, I am creating this post to show why I feel pitchers should bench press.

So, the muscles activated when throwing are…

Group II muscles accelerated the arm and baseball forward in space. These muscles, the pectoralis major, serratus anterior, sub scapularis, and latissimus dorsi, had stronger activity during the propulsive phase of the pitch (1).

The muscles activated by bench press are…

The sternocostal head of the pectorals major was more active during the press from a horizontal bench than from a decline bench. Also, the clavicular head of the pectoralis major was more active with a narrow hand spacing. Anterior deltoid activity tended to increase as trunk inclination increased. The long head of the triceps brachia was more active during the decline and flat bench presses than the other two conditions, and was also more active with a narrow hand spacing, Latissimus doors exhibited low activity in all conditions (2).

So the same muscles are activated, which should mean that it will increase velocity. Now, lets test it out…

Twenty- four elite collegiate baseball players (age 18-20 years) trained twice per week for 8 weeks. The isotonic resistance-training protocol consisted of 3 sets of 8 to 10 repetitions maximum (RM) for the first 4 weeks. Thereafter, they performed 3 sets of 6RM to 8RM for the last 4 weeks. The isotonic exercises included the conventional bench press and barbell pullover exercises that are commonly used by baseball players to train upper-body muscles in throwing. The results of this study showed a 4.1 and 22.8% increase in throwing velocity and upper-body muscular strength, respectively (3)………
Effect of resistance training on release velocity. – Bench press – 3 sets, 5–6 reps – 85% of 1 Repetition Maximum – 3 Sessions per week – Yes it had a significant increase in throwing velocity (17–18%) (4)………
Post hoc analysis showed a significantly higher mean throwing velocity for the training group following 8 weeks of strength training. The Treatment Group Participated in an 8 week supervised upper body strength training program consisting of 11 exercises, listed below (5).
Flat Bench Press
Tricep Extension
Upper Lat Pulldown
Biceps Curl
Lateral Row
Shoulder Press
Internal Shoulder Rotation
External Shoulder Rotation
Horizontal Shoulder Abduction
Horizontal Shoulder Abduction
Shoulder extension
Potteiger et al. found a significant increase in throwing velocity (2.3 mph) using a traditional upper- and lower- body isotonic exercise protocol with collegiate position players. These investigators used a progressive resistance-training protocol with the following exercises: the bench press, military press, latissimus pull-down, biceps curl, triceps extension, squat, leg curl, and leg extension (6)

So, I think this should prove the point that the bench press is okay?

To avoid pattern overload, it would be wise to
A) not bench with a fatigued shoulder from a repetitive motion like throwing
B) try to isolate the chest. use a narrow grip on a horizontal bench. keeping the elbows in helps activate more chest, too.

What’s hoc?

Post hoc analysis is when the researchers analysts their data to check for trends/patterns that they were not expecting/did not test for.

Does it stand for anything? If so, what is it?

Thank you @cursed.legend

I don’t believe so, although I may be wrong.

Post Hoc is Latin for after this.

In the design and analysis of experiments, post hoc analysis (from Latin post hoc, “after this”) consists of looking at the data—after the experiment has concluded—for patterns that were not specified a priori

a priori is Latin for from the earlier

Great explanation.
