Weighted Mean

Weighted Mean

While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

Force and Momentum

Force and Momentum

Force and momentum are intimately related. Force acting over time can change momentum, and Newton's second law of motion can be stated in its most broadly applicable form in terms of momentum. Momentum can be applied to systems where the mass is changing, such as rockets, as well as to systems of constant mass. Also, momentum continues to be a key concept in the study of atomic and subatomic particles in quantum mechanics. One can consider systems with varying mass in some detail; however, the...

Summary

Training with a 3-kg medicine ball significantly improved overhead throwing speed in high school students. A double training workload showed greater gains, indicating training volume is key for enhancing ball throwing performance.

Sports Science
Biomechanics
Exercise Physiology

Background:

Overhead throwing is a fundamental skill in many sports.
Optimizing throwing speed is crucial for athletic performance.
The impact of specific training loads on throwing velocity requires further investigation.

Purpose of the Study:

To examine the effect of single versus double training workloads using a 3-kg medicine ball on throwing speed.
To assess how training with a 3-kg medicine ball influences throwing speed with various other ball weights.

Main Methods:

Forty high school students were divided into a control group and two training groups (single and double workload).
Training involved overhead throwing with a 3-kg medicine ball for 6 weeks, twice weekly.
Throwing speed was measured using 0.35-kg, 0.45-kg, 1-kg, and 3-kg medicine balls before and after the training period.

Main Results:

Both training groups showed significant increases in throwing speed for 0.35-kg, 1-kg, and 3-kg balls (p ≤ 0.05).
The double workload group exhibited the most substantial improvements in throwing speed.
No significant change in throwing speed was observed with the 0.45-kg ball.

Conclusions:

Training workload volume is a critical factor for enhancing ball throwing performance in adolescents.
Consistent training with a 3-kg medicine ball can improve throwing velocity across a range of lighter ball weights.
These findings have implications for designing effective medicine ball training programs for athletes.
