What does the principle of specificity require when designing a training program for a 100m sprinter?

• A. Focus solely on long-distance endurance runs
• B. Include only resistance training with no sprint work
• C. Ignore sprint mechanics and focus on swimming
• D. Training should mimic the movement patterns, energy systems, intensities, and velocities of the 100m sprint; include sprint work, plyometrics, and speed endurance

Answer: (D)

Specificity means training should mirror the demands of the event in movement patterns, energy systems, and velocities. For a 100m sprinter, that means practicing the sprint pattern itself—start mechanics, acceleration, and reaching and maintaining maximal velocity—while conditioning the body to perform at those speeds. So training should combine sprint work with plyometrics to boost explosive power and speed endurance to cope with fatigue near the end of the race. The energy demands of a 100m sprint are dominated by the phosphagen system with a significant glycolytic contribution, so workouts are short, near-maximal efforts with short rests to train neuromuscular efficiency and speed rather than long-duration endurance. Long-distance endurance won’t develop sprint-specific power and technique; focusing only on resistance training without sprint work misses the required movement and speed demands, and switching to a non-sport activity like swimming ignores the sprint mechanics needed on the track.
