Exercises Tailored to Meet the Needs of Submarine Pitchers
Title
Exercises Tailored to Meet the Needs of Submarine Pitchers.
Creator
Mullaney, Kurtis
Abstract / Description
Background: In order to remain healthy while performing at a high level, athletes must exercise in a manner that is functional and translatable to the movement being produced during sport. In order to accomplish this, exercises are often modified to meet the specific demands of different sporting activities. Purpose: Although many studies have been performed on several aspects of baseball pitching, few studies have focused on the submarine pitcher. This pilot study investigated the difference...

In order to accomplish this, exercises are often modified to meet the specific demands of different sporting activities. Purpose: Although many studies have been performed on several aspects of baseball pitching, few studies have focused on the submarine pitcher. This pilot study investigated the difference in the activation patterns of select muscles for subjects conducting two exercises: the cable retraction with external rotation exercise and the modified version of the same exercise, which had been tailored to the submarine pitcher. The following research was performed to advance the literature devoted to the specific needs of submarine pitchers, and to raise awareness on the lack of literature devoted to this style of throwing. Subjects: 16 healthy males ages 18-35 with previous high school, college, and/or professional baseball experience participated in this study. Methods: Each subject was observed performing five repetitions of the two exercises, while motion and muscle activation patterns of the posterior deltoid, the infraspinatus, the middle trapezius, and the lower trapezius were captured using the Qualisys Motion Capture System in conjunction with the Noraxon SEMG system. Results: No significant differences were found between the two exercises in terms of muscle activation patterns of the four muscles being studied. A positive correlation was found between the muscle activation patterns of the two exercises, indicating that both exercises may accomplish the same goal when it comes to strengthening the four targeted muscles. A significant difference was found in the angle of abduction in which peak muscle activation occurred for the posterior deltoid (13°), the middle trapezius (17°), and lower trapezius (14°).

Shoulder Strength and Conditioning for Injury Prevention in Baseball Players
Title
Shoulder Strength and Conditioning for Injury Prevention in Baseball Players.
Creator
Jones, Kevin Thomas
Abstract / Description
According to a survey completed by the National Federation of State High School Associations, baseball is the third most popular boys sport played. In the 2012-2013 year season, 15,632 schools played high school baseball across America. These schools' teams were comprised of 474,791 student athletes. A recent study reports that 63.3% of injuries in high school baseball are to the upper extremity. (Shanley, Rauh, Michener, & Ellenbecker, 2011). Bonza, Fields, Yard, and Comstock (2009) reported...
Show moreAccording to a survey completed by the National Federation of State High School Associations, baseball is the third most popular boys sport played. In the 2012-2013 year season, 15,632 schools played high school baseball across America. These schools' teams were comprised of 474,791 student athletes. A recent study reports that 63.3% of injuries in high school baseball are to the upper extremity. (Shanley, Rauh, Michener, & Ellenbecker, 2011). Bonza, Fields, Yard, and Comstock (2009) reported that 17.7% of high school baseball players injure their shoulders. This is a greatest percentage of injuries among baseball players. It is for this reason that shoulder injury prevention is of the upmost importance for baseball pitchers. This following scholarly paper provides a review of the phases of the baseball pitch including the structural and muscular requirements of each phase. The paper also reviews current literature used to produce an evidence based shoulder strength and conditioning program that may be implemented by institutions with limited financial resources, limited facilities, and without a qualified strength and conditioning professional. The case report describes how this program was implemented as part of the overall strength and conditioning program used during the fall baseball season at Gordon State College in Barnesville, GA. The development of the shoulder strength and condition program took into account current research as well as the financial and equipment limitations, availability of qualified strength and conditioning professionals, and training time allotted for the strength and conditioning of National Junior College Athletic Association student athletes.

The Use of Ultrasound Imaging in Assessing UCL Width for College Baseball Pitchers
Title
The Use of Ultrasound Imaging in Assessing UCL Width for College Baseball Pitchers.
Creator
Smith, Brandon
Abstract / Description
Context: Injuries to the Ulnar Collateral Ligament (UCL) of the elbow are common in overhead throwing athletes. A repetitive valgus force during the throwing motion places significant stress on the UCL. More research needs to be conducted to investigate new methods to assess potential thickening of the anterior bundle of the UCL, in order to understand ligament changes that may occur throughout the season. Objective: To examine the reliability of measuring the width of the UCL throughout a...
Show moreContext: Injuries to the Ulnar Collateral Ligament (UCL) of the elbow are common in overhead throwing athletes. A repetitive valgus force during the throwing motion places significant stress on the UCL. More research needs to be conducted to investigate new methods to assess potential thickening of the anterior bundle of the UCL, in order to understand ligament changes that may occur throughout the season. Objective: To examine the reliability of measuring the width of the UCL throughout a constant valgus force by means of ultrasound imaging by a novice student physical therapist, and to determine the presence of any differences in ligament width between the two measurement dates within the season. Design: Quasi-experimental quantitative repeated measures design. Participants: Thirteen Division I college men’s baseball pitchers participated with a mean age of 20.4 ± 1.45 SD years (range, 18 to 23) and body mass index (BMI) 24.56 ± 1.78 SD (range, 21.9 to 27.6). Methods: Ultrasound images were obtained of the UCL on the participant’s throwing arm using a GE LOGIQ E ultrasound unit. Participants were placed in supine with a wedge placed underneath their hand to maintain their elbow at a 30 degree angle. A 3 kg valgus force measured by a hand held dynamometer was applied 20 centimeters distal to the medial epicondyle to maintain a constant 5 Nm valgus stress among participants. The anterior band of the UCL was imaged at the beginning of the baseball season then again the following month. Three images were measured during each session. The post imaging measurements were performed at the mid substance and the apex of the trochlea and conducted by a single novice third year student physical therapist with two 30 minute training sessions using the ultrasound unit. Results: Intra-rater reliability as expressed by ICC (3, 3) was .929 & .935 for the apex of trochlea measurement site and .861 & .920 for the mid-substance measurement site, indicating excellent intra-rater reliability. There was no statistically significant difference between the measurements obtained on the two testing dates (Apex of mean width 2.90mm & 2.92mm; t= -.155; p ≥ ≥0.5) and (Mid-substance mean width 4.49 mm & 4.44 mm; t= .571; p ≥ ≥0.5) Conclusions: This study demonstrated that a novice ultrasound imaging operator with minimal training can reliably measure the width of the anterior band of the UCL. There was also no significant difference in UCL width from the beginning of the season and one-month into the season. Further research is recommended to perform multiple imagining sessions throughout the year to determine the long term physiological effects of overhead throwing on the anterior band of the UCL and to study the connection between UCL width changes, tissue quality, and injury risk.
