← Sports & EntertainmentA baseball pitcher changes their throwing motion to decrease the time between maximum shoulder external rotation and ball release. Which effect dominates?
A)Increased total kinetic energy transfer
B)Decreased elbow stress during acceleration
C)Reduced peak force application duration✓
D)Greater range of motion during follow-through
💡 Explanation
Reducing the time between maximum shoulder external rotation and ball release leads to a shorter period for force application, because the kinetic chain's energy transfer is truncated. Therefore, the peak force application duration is reduced, rather than increasing total kinetic energy transfer, which requires a longer period.
