What are the principles of specificity and reversibility in training, and how do they influence program design?

• A. Specificity means training should mimic any sport; reversibility means gains stay forever.
• B. Specificity: training should mimic sport demands; reversibility: gains fade without ongoing training. Design programs to match sport needs and include maintenance to prevent detraining.
• C. They are unrelated principles.
• D. Reversibility means you reverse the training plan daily.

Answer: (B)

Specificity means training adaptations are driven by the exact demands you place on the body—movement patterns, muscle groups, speeds, and energy systems that mirror the sport. Reversibility means the gains you’ve built will fade if the training stimulus is removed or reduced. Together, they shape program design by ensuring workouts target the sport’s needs and by including ongoing or maintenance work to protect adaptations during breaks or between cycles.

So, you design to match sport demands: choose exercises, intensities, and tempo that reflect how the sport is played, so improvements transfer to performance. And you plan for maintenance to prevent detraining: keep essential elements present at reduced volume or with smart periodization so gains aren’t lost when the schedule changes or competition schedules interrupt regular training.

The other ideas miss this alignment. One option suggests mimicking any sport and that gains last forever, which ignores both the specificity of demands and the reality of detrainment. Another implies the principles are unrelated, which isn’t true, and another wrongly states reversibility means reversing the plan daily.
