Therefore, the primary aims of our study were to explore the associations (1) between measures of hip ROM and strength and energy flow through the trunk and pitching-arm segments, and (2) between energy flow through the trunk and pitching-arm segments and pitch speed during the windmill softball pitch in a sample of youth softball athletes. The associations between hip ROM and strength and trunk and upper extremity energy flow are currently unclear. Identifying relationships among functional measures, energy flow, and pitch speed can assist in the development of practices that both decrease injury susceptibility and improve performance. Similarly, understanding the relationship between energy flow and pitch speed is especially valuable for athletes and coaches as they continue to improve player-development strategies. 16 Furthermore, bridging the gap between clinical measures such as joint ROM and muscular strength with laboratory measurements such as energy flow through the kinetic chain could prove beneficial in providing a knowledge base for the development of injury-prevention protocols. ![]() 12 Therefore, describing the patterns of energy flow between segments during the windmill softball pitch would be interesting for sports medicine personnel from the training, rehabilitative, and injury-prevention perspectives. ![]() 12 Energy flow between segments has emerged as one of the most critical concepts related to injury susceptibility 13– 15 because inefficient proximal-to-distal energy transfer can result in distal extremity compensation to maintain performance. 11, 12 Specifically, energy flow is defined as the movement of mechanical energy through the human body, including energy generation and absorption by muscles at joints and energy transfer between segments. Energy-flow analysis has recently gained popularity for enabling sports medicine professionals to characterize the flow of mechanical energy during open kinetic chain sport movements such as the baseball pitch and tennis serve.
