Which term describes changes that occur soon after starting an exercise?

• A. Delayed onset muscle soreness
• B. Baseline changes
• C. Acute changes
• D. Chronic adaptations

Answer: (C)

Acute changes describe the immediate, short‑term responses your body makes when you start exercising. As soon as you begin, heart rate and breathing speed up, blood flow shifts to working muscles, and metabolic and hormonal activity ramps up to meet the higher energy demand. These adjustments happen within seconds to minutes and usually return toward baseline after the activity ends. This is different from delayed onset muscle soreness, which appears hours to days after exercise, and from chronic adaptations, which are long-term structural and functional changes from regular training. Baseline changes refer to shifts in your starting measurements over time, but they don’t capture the initial, moment‑to‑moment responses during the workout.
