“…The results of this study suggest a potential influence of strength on hitting performance. Indeed, previous studies have found improvements in several hitting-related factors (i.e., bat swing velocity and batted ball velocity) following RT [5,6,9]. The collective evidence suggests that strength training may be beneficial for hitting performance among collegiate baseball players.…”

“…The "drug era" of the 1990s established a shift in many people's perceptions of the importance of strength and its development in baseball, particularly its effect on power hitting (e.g., home runs, slugging % and extra base hits) [3]. Strength has been associated with higher hitting related variables [4][5][6], typically in controlled field-based testing or laboratory-based testing (e.g., bat speed, batted ball velocity).…”

“…Additionally, increasing bat swing velocity can increase the speed at which the ball is projected off of the bat (batted ball velocity), increasing the chances of a productive outcome [4,7]. Various training protocols have been shown to increase bat swing velocity, including the use of free weights, bats of various weights, plyometric exercises, medicine balls, and weightlifting movements [5][6][7]9]. However, though strength and hitting ability have a well-established relationship [10][11][12][13], it is uncertain whether long-term changes (e.g., years) in strength coincide with improvements in "on-field" hitting outcomes, such as home runs.…”

The purpose of this longitudinal, descriptive study was to observe changes in maximal strength measured via isometric clean grip mid-thigh pull and home runs (total and home runs per game) across three years of training and three competitive seasons for four National Collegiate Athletic Association (NCAA) Division 1 baseball players. A one-way repeated measures analysis of variance (ANOVA) was performed, revealing significant univariate effects of time for peak force (PF) (p = 0.003) and peak force allometrically scaled (PFa) (p = 0.002). Increases in PF were noted from season 1 to season 2 (p = 0.031) and season 3 (p = 0.004), but season 2 was not significantly different than season 3 (p = 0.232). Additionally, increases in PFa were noted from season 1 to season 2 (p = 0.010) and season 3 (p < 0.001), but season 2 was not significantly different than season 3 (p = 0.052). Home runs per game rose from the 2009 (0.32) to 2010 season (1.35) and dropped during the 2011 season (1.07). A unique aspect of the study involves 2010 being the season in which ball-bat coefficient of restitution (BBCOR) bats were introduced to the NCAA competition.

“…Maturation plays a key role in the development of stature, body weight, and skeletal muscle strength (De Ste Croix, Armstrong, & Weisman, 1999). Szymanski et al (2007) reported an increase in bat linear velocity due to the implementation of a strength training protocol on high school baseball players. Moreover, Gebhardt, Bowers, and Archer (1991) found a correlation between muscle strength and hitting success.…”

Determining and understanding baseball batting mechanics at various competition levels may help players and coaches identify key kinematics crucial to being a successful hitter. The purpose of this study was to compare batting kinematics across competition levels. Kinematic and temporal data were analysed for 170 male batters (youth n = 33; high school n = 69; college n = 22; professional n = 46) using 3D motion capture (480 Hz). The results showed differences in angular positions between competition levels during the five phases of the swing, with the greatest differences seen between the youth and professional batters. At the instant of ball contact, professional batters held the bat farther away from their body, with greater back shoulder abduction (35°) and less back elbow flexion (78°) compared to youth (27° and 89°, respectively). These differences were associated with greater back elbow extension velocity for professionals (1539°/s) compared to youth (1174°/s). Additionally, higher level batters had higher bat angular and linear velocities compared to the youth batters. As batters progress through their career, they should focus on their back arm by keeping their elbow up and their arm extended in front of them.

“…In previous studies of baseball batting, a number of kinematic analyses were reported (Race, 1961;Mcintyre and Pfautsch, 1982;Welch et al, 1995;Szymanski et al, 2007;Escamilla et al, 2009;Inkster et al, 2011). According to these reports, the knee joint angle, torso rotational velocity, elbow extension velocity and other factors were discussed as important motions to increase bat head speed.…”

The purpose of this study was to identify mechanisms to increase bat head speed in baseball batting, from the view-point of kinetics. The batting motion of ninety-nine amateur baseball players was recorded with a motion capture system, and the kinematics and kinetics of the bat were analyzed. The bat's rotational power increased with the torque exerted on the bat's grip. However, torque and rotational power declined just prior to impact. It can be interpreted that these declines arise from a decrease in torque exerted by the wrist's periarticular muscles as the bat's rotational velocity increases (muscle force-velocity relationship). On the contrary, the bat's translational power increased just prior to impact. Judging from the relationship between the force exerted on the bat's grip in the direction of the bat's long axis and the bat head speed, the bat's translational power seems to depend on the bat's grip velocity in the direction of the bat's long axis. It was revealed that the bat's energy, by the application of rotational and translational power at diŠerent times, contributes to an increase in bat head speed in baseball batting.
