Which of the following is an example of a readiness metric used in H2F?

• A. Hydration status
• B. Sleep duration
• C. Hair color
• D. Shoe size

Answer: (B)

Readiness metrics gauge how prepared an individual is for training by reflecting recovery and current capacity. Sleep duration is a fundamental indicator because it directly mirrors how well the body has recovered and how alert and mentally sharp the person will be during performance. Adequate sleep supports decision-making, reaction time, mood, hormonal balance, and tissue repair, all of which influence training quality and injury risk. In H2F practice, monitoring nightly sleep helps coaches tailor training loads, plan recovery days, and schedule sessions to match an athlete’s state of readiness. Hydration status also affects readiness, but sleep duration is a widely used, practical daily marker that captures overall recovery status. Hair color and shoe size don’t reflect current readiness or recovery and aren’t used to gauge performance capacity.
