Coaches can obtain an expectation of a pitcher's performance by comparing his pitching velocity with the predicted value derived from the statistical model presented herein, and the room of growth by comparing his current strength to average strength growth after being drafted and trained with professional coaches. These field tests can be adopted in tryout events to predict a prospect's potential and to identify underestimated players. Overall, these measures explained 23% of the variance in the predicted pitching velocity.
Among the measures, the ratio of loaded CMJ to CMJ, ratio of first 10-m sprint time to 30-m sprint time, and height were significant contributors to pitching velocity. Multiple regression indicated a moderate correlation between these tests and pitching velocity (adjusted R2 = 0.230, p = 0.0003). The outcome measures included maximum external shoulder rotation, maximum internal shoulder rotation, countermovement jump (CMJ) height, 20-kg loaded CMJ height, 30-m sprint time, height, age, and weight tests. The measurements and tests in tryout settings should be easy to implement, take short time, do not need high skill levels, and correlate to the pitching velocity. We use half day to test 64 players, and the result of measurement are used to develop a model for predicting pitching velocity of amateur adult pitchers (age: 23.9 ± 2.8 years height: 180.3 ± 5.9 cm weight: 81.4 ± 10.9 kg). In this study, we adopted field tests executed using affordable equipment in a tryout event for a professional baseball team in Taiwan, 2019. However, some measurements require expensive equipment, and some tests need familiarity to perform well. Several studies have investigated factors influencing baseball pitching velocity. A thorough understanding of the mechanics of this motion, along with specific exercises to target the specific actions of each phase, may allow for throwers, regardless of their age and experience, to minimize injury risk. The throwing cycle is a complex motion that places various stresses throughout the thrower’s body, from the ankle to the core, and from the back to the shoulder and elbow. With a clear understanding of the biomechanics of throwing, we can develop an injury prevention routine to minimize unnecessary stresses throughout the kinetic chain. Throwing a ball places extreme stress on the body, notably the shoulder and elbow joints. To help minimize the risk of injury to overhead throwing athletes, a thorough understanding of the throwing motion is critical. In doing so, we sought to provide a warm-up strategy that can be added to every baseball player’s daily on-field routine that is tailored to each phase of the throwing motion.

The goal was to determine the underlying causes of a deficiency in throwing mechanics throughout a throwing motion, and to provide an evidence-based approach on how to prevent injuries caused by a lack of proper mechanics. This review examines the relationship between the baseball pitching motion and the kinetic chain.
While pitchers can be successful and carry excess bf%, results indicate potential performance disadvantages associated with having an increased bf%.
BMI and FFMI were positively associated with pitch speed while bf% and FMI were negatively associated with pitch speed. Univariate follow-up analyses showed healthy bf% pitchers presented greater weight-normalized peak medial GRF (F1,30=7.17, p=.012).
Multivariate analysis of variance revealed pitcher group GRFs differed significantly (F3,30=3.45, p=.030).

GRF data were collected during pitch propulsion via a force plate, pitch speed was captured using a radar gun, BMI was calculated from pitcher height and mass, and fat free mass index (FFMI) and fat mass index (FMI) were calculated using DEXA data and pitcher height. Thirty-two female high-school softball pitchers (1.70±.06 m, 76.09☑7.50 kg, 15☑ yrs) completed dual-energy x-ray absorptiometry (DEXA) scans. Therefore, the purpose of this study was to examine the differences in ground reaction force (GRF) development between two groups of pitchers: those with a high-fat percentage (≥32 bf%) and a healthy-fat percentage (<32 bf%). Given the importance of propulsion during pitching, those with high bf% may have an advantage performance-wise. Softball pitchers with a high body-fat percentage (bf%) can often be successful, despite the heightened risk of injury associated with high bf%.
