The term that describes the degree to which athletes move both safely and effectively is called what?

• A. Efficiency
• B. Technique
• C. Efficacy
• D. Kinesiology

Answer: (A)

Movement efficiency is the idea that describes how well an athlete moves with both safety and effectiveness in mind. When someone moves efficiently, they perform the required task with good form while using the least amount of energy possible and with reduced risk of injury. This combines quality of movement (effectiveness) with careful, economical use of effort (safety and energy conservation).

Technique refers to the specific form or method of performing a skill, which is part of good movement but doesn’t by itself measure how economically or safely that movement is carried out. Efficacy focuses on whether the desired result is achieved, but not necessarily on how safely or economically that result is produced. Kinesiology is the study of human movement, not the description of how safely and effectively movement occurs in practice.

So, the term that best fits describing both safe and effective movement is efficiency.
