“…However, the faster throwers in this study had decreased ROM compared with their slower counterparts. These findings are similar to the study by Robb et al (19) that reported moderate correlation (r = 0.50, p , 0.04) between lower total hip rotation arc passive ROM on the nondominant side and throwing velocity among professional baseball pitchers. Excessive rotation at the hips can put the pelvis and foot in a more open position, thereby prematurely initiating the arm cocking phase and resulting in loss of kinetic energy in the lower extremity (19).…”

Talukdar, K, Cronin, J, Zois, J, and Sharp, AP. The role of rotational mobility and power on throwing velocity. J Strength Cond Res 29(4): 905-911, 2015-Sound rotational power and mobility are an integral component in functional performances, such as throwing and striking. The purpose of this study was to examine the role of rotational power and mobility on cricket ball-throwing velocity. Eleven professional cricketers and 10 under-19 club-level cricketers performed the chop and lift, seated and standing cricket ball throw, seated and standing side medicine ball throw, and seated active thoracic rotation range of motion (ROM) and hip rotation ROM on one occasion. Participants were divided into 2 groups (fast and slow) based on their standing cricket ball-throwing velocity. The seated and standing cricket ball throw on the dominant side was significantly different (p , 0.00) between fast and slow throwers (11.03 and 10.7 km$h 21 , respectively). Muscular performance measures, such as bilateral thoracic rotation ROM, hip external rotation ROM on the dominant side, and force and work required in the chop, were significantly different (p # 0.05) between fast and slow throwers. Faster throwers in this study displayed greater force (18.4%) and work (31.2%) outputs in the chop compared with the slower throwers; however, slower throwers showed significantly greater ROM in the thoracic (13.4-16.8%) and hip regions (11.8%). It was concluded that greater ROM at proximal segments, such as hips and thoracic, may not increase throwing velocity in cricket as reduced ROM at proximal segments can be useful in transferring the momentum from the lower extremity in an explosive task such as throwing.

“…Also progression to return to sport without the adequate mental confidence in the injured side could contribute to poor performance. Finally early discontinuation of a maintenance program could result in weakness or reduced neuromuscular control leading to re-injury or kinetic chain breakdown as observed in patients with hip pathology and upper extremity dysfunction [42,43].…”

Rehabilitation guidelines following hip arthroscopy have been presented in the literature with common themes consisting of initial protection, restoration of lumbo-pelvic stability, neuromuscular re-education, and return to sport training. The purpose of this review is to present hip arthroscopy guidelines in 4 phases and to address common pitfalls that may delay the rehabilitative process. The goal of phase 1 should be to protect healing tissues through activity modifications. Phase 2 intends to return the patient to pain-free community ambulation without compensation or irritation. A review of hip muscular actions during gait is presented to guide exercise progressions during this phase. Phase 3 should reestablish neuromuscular control through strength and endurance training to provide the foundation for return to functional activities or sports training progressions. The last phase of rehabilitation is dedicated to reestablishing power, speed, agility, and skill for advanced sports and advanced functions.

“…Among professional baseball pitchers, however, Robb et al (2010) found that hip rotation range of motion was greater on the pitching side. In this study, our analysis suggests laterality in hip external rotation angle.…”

The purpose of this study was to measure range of motion among professional women baseball players and to identify specific attributes through comparison against university men players. Subjects were 53 professional women baseball players (average age 21.9 ± 2.9 years) and 23 university men baseball players (19.8 ± 0.8 years). Measurement of shoulder external and internal rotation, neck and thoracolumbar rotation, hip internal and external rotation, SLR and HBD revealed sex differences and laterality. Women players had higher lower limb flexibility values compared with men, and like men, demonstrated laterality in range of motion in the limbs and trunk. Findings from this study may provide reference values that can be applied to women's conditioning programs.
