“…Several of the exercises are performed with very powerful throws of the medicine ball. Several authors have indicated that these exercises can be adapted into a very reliable and valid method of testing power and strength in both the lower and upper body 17,[22][23][24][25] . These exercises work well to test core strength due to the exercises requiring the core to act as an intermediary to transfer forces to the extremities.…”

The purpose of this study was to determine the effects of core strength on the transfer and production of forces in the extremities. Twenty-five division 1 collegiate football players performed a series of medicine ball throws in the forward, reverse, right and left directions in a static and dynamic position. The results of the medicine ball throws were compared to several athletic performance measurements including: push press power, 1RM squat, 1RM bench press, countermovement vertical jump, broad jump, 40 yard dash, 20 yard dash, pro agility to the right and left, and the L drill. Several strong correlations were found in both the static and dynamic medicine ball throw positions when compared to the performance measures. Static reverse correlated with vertical jump (CMJ) (r=0.44), broad jump (BRD)(r=0.5) and push press power (PWR)(r=0.46). Static left (StL) and static right (StRi) correlated with PWR (r=0.59), (r=0.65) respectively, and Vel (r=0.52)(r=0.6), respectively. Fewer dynamic throws correlated significantly with the performance variables. Dynamic left (DyL) and Dynamic right (DyRi) correlated with PWR (r=0.53), (r=0.63) respectively, and Vel (r=0.55),(r=0.61) respectively. Dynamic forward (DyFw) correlated with the 1RM squat (r=0.45). A stepwise regression for push press power prediction reveals that 1RM squat is the best predictor of push press power.The results indicate that core strength does have a significant effect on the ability of an athlete to create and transfer forces in the extremities. iv ACKNOWLEDGEMENTS

The effects of plyometric vs. dynamic stabilization and balance training on power, balance, and landing force in female athletes, J. Strength Cond. We.s. 20(2): 345-;i53. 2006.-Neuroniascular training protocols that include both plyometrics and dynamic balance exercises can significantly improve biomechanics and neuromuscular performance and reduce anterior cruciate ligament injury risk in female athletes. The purpose of this study was to compare the effects of plyomelrics (PLYO) versus dynamic stabilization and balance training (BAL) on power, balance, strengtb. and landing force in female athletes. Either PI-,YO or BAL were included as a component of a dynamic neuromuscular training regimen that reduced measures related to ACL injury and increased measures of performance. Nineteen bigh school female athletes participated in training 3 times a week for 7 weeks. The PLYO in = 81 group did not receive any dynamic balance exercises and the BAL in -11) group did not receive any maximum efTort jumps during training. Pretraining vs. posttraining measures of impact force and standard deviation of center of pressure (COP) were recorded during a single leg hop and bold. Subjects were also tested for training effects in strength (isokinetic and isoinertial) and power (vertical jump). Tbe percent cbange from pretest to posttest in vertical ground reaction force was significantly different between tbe BAL and PLYO groups on tbe dominant side ip < 0.05). Botb groups decreased tbeir standard deviation of center of pressure (COP) during hop landings in tbe medial/lateral direction on their dominant side, whicb equalized pretested side to side differences. Both groups increased hamstrings strengtb and vertical jump. The results of this study suggest tbat both PLYO and BAL training are effective at increasingmeasuresof neuromuscular power and control. A combination of PLYO and BAL training may further maximize tbe effectiveness of preseason training for female athletes.

“…Adequate testretest reliability of the BOMB throw has been previously demonstrated in the literature. 6 To reduce the potential influence of familiarization on BOMB throw performance, 12 all subjects completed a practice BOMB throw protocol 8 weeks before the actual testing protocol. In addition, a post hoc paired samples t-test indicated there was not a significant difference between the 2 BOMB throw test trials (t42 = -1.207, p = 0.234), suggesting that the previously completed familiarization session and subsequent practice attempt likely minimized any familiarization effect on BOMB throw performance.…”

“…During the BOMB throw, the participant attempts to explosively throw a medicine ball as far as possible in a backwards direction. 6 Although the validity of the BOMB throw has been examined among various athlete populations, [7][8][9] it has yet to be examined among a tactical athlete population, such as firefighters. Furthermore, since total body power output during a vertical jump test has been previously demonstrated as a significant predictor firefighting performance, 4 the BOMB throw may prove to be a useful tool to assess the total body power output among firefighters.…”

Objectives:To examine the relationships between performance during a backward overhead medicine ball (BOMB) throw and measures of countermovement jump (CMJ) performance among firefighter candidates. Design: Cross-sectional study. Methods: Forty-three firefighter candidates volunteered to participate in this study (age = 28.1 ± 7.1 yrs; height = 180.6 ± 6.0 cm; weight = 88.6 ± 12.3 kg). Bivariate Pearson correlations were used to examine the relationship between BOMB throw performance (m/kg) and measures of CMJ performance, including: peak CMJ height (cm/kg), peak CMJ force output (N/kg), peak CMJ velocity (cm/sec/kg), and peak CMJ power output (W/kg). Results: Statistically significant (p < 0.05) correlations were identified between: BOMB throw and peak CMJ height (r = 0.693, p < 0.001), peak CMJ force output (r = 0.349, p = 0.022), and peak CMJ velocity (r = 0.477, p < 0.001). Although significant relationships were identified between BOMB throw performance and several of CMJ performance measures, BOMB throw performance accounted for little of the total variance between these measures (R 2 = 7-48%). Furthermore, the relationship between BOMB throw and peak CMJ power output was not statistically significant (r = 0.292, p = 0.057). Conclusions: These results imply that the BOMB throw lacks criterion-reference validity to other standard field-based measures of power output. Thus, practitioners should exhibit caution when utilizing the BOMB throw to assess power output among firefighter candidates. In addition, future research should examine the criterion-reference validity of other field-expedient assessments among firefighter candidates and active-duty firefighters.
