Baseball
Move · High-Intensity · Movement, Typed Supps
Almost all of the physical cost of baseball is paid in a handful of seconds spread across three hours.
Stage by stage
- Most of the game (Low mean intensity): Long periods of standing and walking keep average metabolic cost well below continuous sports.
- During a play (One to three second bursts): Swings, sprints and throws are near-maximal efforts lasting a couple of seconds, generated proximal-to-distal from the legs.
- Late cocking phase (Ligament near its limit): With the shoulder maximally externally rotated, elbow valgus torque approaches the ulnar collateral ligament's tensile tolerance.
- Weeks later (Tissue adapts unevenly): Muscle strength and timing improve quickly while tendon and ligament lag, which is why cumulative pitch volume drives injury risk.
Muscles trained
- Primary: shoulders, forearms, obliques
- Secondary: quads, triceps, heart
Intensity
5 METs (Softball or baseball, fast or slow pitch, general (Taylor Code 440)).
Time to effect
- Weeks: Hand-eye timing against faster pitching sharpens within a few weeks of regular batting practice.
- Months: Rotational hitting power and throwing arm strength build over a couple of months, though the shoulder and elbow connective tissue involved in throwing adapts more slowly than the muscle around it.

Common myth
“Baseball isn’t much of a workout — there’s too much standing around.” In reality: The sport is built on short, near-maximal bursts rather than continuous effort: a pitcher’s throwing arm generates some of the highest joint torques measured in any sport, which is exactly why elbow ligament injuries requiring Tommy John surgery are so common.
