True or False: Reaction times cannot be affected or improved by exercise or strength training.

The statement that reaction times cannot be affected or improved by exercise or strength training is false. Exercise and strength training can significantly enhance reaction times through various mechanisms. Regular physical activity improves the neuromuscular system's efficiency, which includes better communication between the brain and muscles. This leads to quicker responses to stimuli.

Additionally, strength training can enhance muscle coordination and balance, allowing for more efficient movements and reactions. Specific training modalities, such as agility drills, plyometrics, and sport-specific activities, can directly target reaction time improvements. These exercises require quick decision-making and rapid muscle contractions, which help develop faster reflexes.

While some factors influencing reaction times, such as age and inherent physiological characteristics, do play a role, the notion that reaction times are immutable is misleading. Continuous engagement in physical training can thus positively impact this vital aspect of physical performance, especially in older adults and across all age groups, contributing to overall fitness and functional ability.
