Objective:
This systematic review and meta-analysis aimed to evaluate the influence of core muscle training on throwing ball velocity among overhead throwing athletes.
Design:
A literature search was performed from inception to July 2023 for randomized controlled trials investigating the effects of core muscle training on overhead throwing ball velocity. The primary outcome was the change in standing throwing ball velocity. The secondary outcome focused on the enhancement of step/jump throwing ball velocity.
Results:
Ten randomized controlled trials were included, revealing a significant improvement in standing throwing ball velocity in the group undergoing core muscle training (Hedges' g = 0.701, 95% confidence interval = 0.339 to 1.063, P < 0.001). Longer treatment duration and a higher frequency of core muscle training sessions per week contributed to improved standing throwing ball velocity. However, core muscle training did not show significant benefits for step (Hedge's g = 0.463, 95% confidence interval = -0.058 to 0.985, P = 0.082) and jump throwing ball velocity (Hedges' g = 0.550, 95% confidence interval = -0.051 to 1.152, P = 0.073).
Conclusions:
Core muscle training significantly enhanced standing ball throwing velocity. However, its effect on step/jump throwing ball velocity was less certain. Further research is needed to explore the impact of core muscle training (especially its long-term effects) on throwing ball velocity.

Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups.
