Interval throwing program:

The ‘Interval throwing program’ is a safe program to follow if you have had a shoulder
injury or a long layoff from throwing competitively.

Throwers who are returning to throwing after injury to the shoulder should follow the
interval-throwing program, exactly, on an every-other-day basis.

The criteria to progress from step to step are that the throwing session was pain free and
there is no residual soreness the next day.

For throwers who are free of injury, but returning to throwing after a lay-off period,
follow the interval-throwing program, on an every-other-day basis, without the rest
periods.

You should use the ‘crow-hop’ method for each throw when performing the interval
throwing session. The ‘crow-hop’ method consists of first a hop, then a skip, followed by
the throw. This method helps simulate the throwing act, allowing emphasis on total body
mechanics involved in the act of throwing. The path of the ball should be an arcing
trajectory, not on a flat line trajectory. You should avoid throwing flat-footed to avoid
placing excess stress on the throwing shoulder in your training program.

Off-season Throwing Program

Following an off-season throwing program is recommended instead of total rest during
the off-season. Continuing to throw at a sub-maximum level will help you avoid the total
de-conditioning of your throwing mechanics, muscle timing, and coordination.

Continue to throw at a frequency of two times a week, following the following outline:

a. Warm-up throwing
f. 45 ft. (25 throws)
g. 60 ft. (20 throws)
h. 90 ft. (15 throws)
i. 120 ft. (10 throws)
