Muscles Used in the Backstroke. Even though you're swimming on your back, you use your abdominals in addition to the muscles of your back -- the latissimus dorsi and spinus erectors -- to support you as you flow through the water during the backstroke.
The average distance for a pitching wedge is 130 to 135 yards; for a sand wedge 115 to 120 yards; and for lob wedges 75 to 95 yards.
In comparing Softball pitching to Baseball pitching, it is the batter s reaction time that has to be determined. For example, at the International and College (and soon to be High School) pitching distance of 43, a batter facing a 60 mph fastball has about 0.42 seconds to react to the pitch.This reaction time is derived from the fact that Distance = Rate times Time.f we assume that the average Softball pitcher releases the ball about 6 feet (yes, superstars like Jenny Finch have a leg stride closer to 7+ feet, but most pitchers do not) from the rubber, the pitching distance equals 37 feet. It takes a 60 mph fastball 0.42 seconds to travel 37 feet.
