What contributes to muscle elasticity prior to exercise?

• A. Increased core temperature
• B. Decreased joint movement
• C. Increased water content in muscles
• D. Decreased blood flow

Answer: (A)

Increased core temperature contributes to muscle elasticity prior to exercise by enhancing the physiological properties of muscle fibers. When core temperature rises, the viscosity of muscle and connective tissues decreases, leading to greater flexibility and range of motion. Warmer muscles tend to be more pliable, which decreases the risk of strains and injuries during physical activity. This improvement in elasticity results from a variety of biochemical and physical changes that occur at higher temperatures, including increased muscle fiber conduction velocity and improved muscle contraction efficiency. Thus, warming up adequately before exercise helps prepare the muscles for the demands of physical activity, making increased core temperature a key factor in enhancing muscle elasticity.
