Which velocities are improved when training the body?

The correct choice highlights that horizontal and vertical velocities are improved through training. When athletes engage in proper strength and conditioning programs, they develop their muscular strength, power, and neuromuscular coordination, which are essential for enhancing both horizontal (forward and backward movements) and vertical (upward movements) velocities.

Horizontal velocity typically refers to the speed at which a person can travel in a straight line, affecting performance in sports that require sprinting, running, or lateral movement. Vertical velocity pertains to how high an individual can jump or how effectively they can elevate themselves against gravity. Training specifically targets muscle groups involved in these movements, allowing for better explosive power and overall speed.

Rigorous training also promotes efficiency in movement patterns, leading to enhanced coordination and better biomechanical techniques, which further improves both horizontal and vertical velocities. As a result, athletes can achieve greater performance in their respective sports and physical activities when focusing on these two aspects.
