Softball

Move · High-Intensity · Movement, Typed Supps

Underhand feels gentler than overhand, but the forces trying to pull a windmill pitcher's shoulder out of its socket are comparable.

Stage by stage

At the plate or on the mound (Proximal-to-distal sequencing): Pelvis, thorax, shoulder and wrist fire in order, with the whole action over in under a second.
Through a game (Cumulative shoulder load): Windmill pitching produces substantial distraction force at release, repeated across high pitch counts.
Between plays (Long low-activity gaps): The demand is near-maximal bursts separated by rest, not sustained cardiovascular work.
Months later (Tissue lags performance): Bat speed and velocity build within a couple of months, while tendon and ligament adaptation lags behind.

Muscles trained

Primary: shoulders, obliques, forearms
Secondary: heart, lungs, quads

Intensity

5 METs (Softball or baseball, fast or slow pitch, general (Taylor Code 440)).

Time to effect

Weeks: Timing on reading pitch speed and location, and the rotational sequencing of a clean swing, sharpen within the first few weeks of regular batting practice.
Months: Throwing velocity and bat speed both build over one to two months of consistent training, though the connective tissue around the throwing shoulder and elbow adapts more slowly than the surrounding muscle.

Common myth

"Softball is a slower, easier version of baseball, so it's less demanding on the body." In reality: Because the pitching distance is shorter and, in fastpitch, delivered underhand at high speed, batters have less reaction time relative to pitch speed than baseball hitters do, and fastpitch pitchers place enormous repetitive load on the shoulder with a very high pitch-count-per-game compared to baseball.
