Effects of Strength vs. Ballistic-Power Training on Throwing Performance

Area of Science:

• Sports Science
• Biomechanics
• Exercise Physiology

Background:

• Novice throwers require effective training strategies to improve shot put performance.
• Understanding the differential effects of strength versus ballistic-power training is crucial for optimizing athletic development.

Purpose of the Study:

• To compare the effects of 6-week strength training versus ballistic-power training on shot put performance in novice male throwers.
• To investigate the resulting muscular adaptations in response to each training modality.

Main Methods:

• Seventeen novice male shot putters were assigned to either a Strength or Power training group.
• Training interventions lasted six weeks, with performance and physiological measures assessed pre- and post-training.
• Measures included shot put throws, countermovement jump (CMJ), Wingate anaerobic test, 1RM strength, ballistic throws, and vastus lateralis muscle characteristics.

Main Results:

• Both Strength and Power training significantly improved shot put throwing performance similarly.
• Strength training led to greater increases in leg press strength (43% vs. 21%) and muscle thickness (10%).
• Power training resulted in greater improvements in CMJ performance (8.5%) and ballistic throws (9.0-25.8%), with significant hypertrophy in type IIx muscle fibers.

Conclusions:

• Six weeks of either strength or ballistic-power training can enhance shot put performance in novice throwers.
• Strength training promotes greater gains in overall muscle strength and mass, potentially more beneficial for novices with lower initial strength.
• Ballistic-power training effectively increases muscle power and may be advantageous in the final preparation phase before competition.
