Which of the following is a non-temperature-related effect of a warm up?

• A. enhanced neural function
• B. disruption of transient connective tissue bonds
• C. elevation of baseline oxygen consumption
• D. increase in muscle temperature

Answer: (C)

Warm-ups produce both effects tied to increasing tissue temperature and effects that prepare the body's systems in a non-heat-dependent way. The rise in baseline oxygen consumption reflects the body's metabolic priming: as you start to warm up, the aerobic energy systems gear up in advance, increasing oxygen use to meet the anticipated energy demand of upcoming activity. This readiness is about metabolic system activation and anticipatory cardiovascular and muscular supply, not a direct result of warmer muscles or tissues. In other words, it’s a systemic preparatory adjustment rather than a heat-driven change.

Other effects of a warm-up—such as faster nerve conduction and improved muscle function that happen because muscles and nerves are warmer—are more directly tied to the rise in tissue temperature. So the elevation of baseline oxygen consumption stands out as the non-temperature-related adjustment.
