Which statement describes the overload principle and gives a practical weekly example?

• A. Overload requires maintaining the same workload to avoid injury
• B. Overload involves increasing training stress beyond the usual level; example: increase weekly load by 5–10% or add an extra session
• C. Overload means reducing volume to avoid fatigue
• D. Overload is achieved by changing the sport entirely

Answer: (B)

Overload means you push training demands beyond what your body is used to, so it has to adapt. The strongest statement captures this by saying you increase training stress above the usual level, such as raising the weekly training load by about 5–10% or adding an extra session. This gradual uptick forces improvements in cardiovascular, muscular, and metabolic systems as they respond to the higher demand. It's important to progress slowly to balance gains with recovery and to reduce the risk of injury. If you keep the workload the same, your body has no impetus to adapt; reducing volume lowers stimulus, and changing the sport doesn't specifically apply the progressive challenge within the same training context.
