RESUMEN
Cricket is one of the most popular games which is played all over the world and its popularity has ever been increasing in the last decade. Fielding is an important dimension of the game as is batting and bowling. With the game being so fast with the introduction of 20 overs game fielding has had an increased demand in the sport. Throwing is considered one of the major and main activities of fielding. Throwing motions involve moving objects spatially using body segments, in particular, hand and arm segments, which can be classified into overarm throws, sidearm throws and underarm throws and divided into throwing objects quickly, accurately and far away. Aim of this study was to find The Correlation of Core Strength and Thoracic Rotation with Speed of Throwing in Cricketers. 31 Cricketers were assessed for their core strength with side rotational medicine ball throws and distance measured, Thoracic rotation in lumbar locked sitting position and measuring with universal goniometer and speed of throws with a BUSHNELL Speed gun. Results of this study showed that Core Strength and Speed of Throws showed a positive, strong and significant correlation whereas Thoracic Rotation and Speed of Throws also showed a positive and significant correlation. Core Strength showed greater clinical and statistical correlation with Speed of Throws than Thoracic Rotation. This study will not only help in preventing throwing injuries but also will help to train and enhance throwing abilities and overall performance
RESUMEN
STUDY DESIGN: A retrospective study. OBJECTIVES: To evaluate the sagittal alignment of cervical spine in AIS. SUMMARY OF LITERATURE REVIEW: Little has been known about the sagittal curve patterns of cervical spine in AIS patients. MATERIALS AND METHODS: One-hundred-thirty-three AIS patients were checked by scanographs and followed up for more than 2 years were divided into cervical kyphosis (> or =+5degrees), lordosis (< or =-5degrees) and straight (-4degrees~+4degrees) groups according to the sagittal curves of cervical spine (C2~C7). Each group was evaluated for thoracic kyphosis, lumbar lordosis, sagittal balance and Cobb's angle on coronal plane. Of the patients, 49 were treated by braces, 84 were surgically corrected (rod derotation in 52, direct vertebral rotation (DVR) in 32). RESULTS: At the initial radiographs, cervical kyphosis was found in 97, lordosis in 23 and straight in 13 patients. In the kyphosis group, cervical kyphosis showed typical patterns of angular kyphosis. Thoracic and upper T-kyphosis (T1~T5) were lower than those in the cervical lordosis group (p=0.000, 0.001, respectively.) Other factors showed no significant differences between the groups. Patients treated by conservative management or by rod derotation had no significant differences in cervical kyphosis during the follow-up periods, though the thoracic hypokyphosis was surgically corrected. On the contrary, patients who were treated by DVR restored cervical lordosis (14/32=43.8%) from initial state showed significant differences in both conservative and rod derotation groups (p=0.008, 0.002, respectively). CONCLUSIONS: Cervical kyphosis in AIS was a compensatory curve correlated with both thoracic hypokyphosis and rotational deformity. Rotational corrections should be considered during the surgical treatment.
