Which pairing correctly matches a health-related fitness component with an example activity?

• A. Body composition — Stretching routines
• B. Cardiovascular endurance — Jog/Run
• C. Flexibility — High-intensity training
• D. Muscular endurance — One-rep max test

Answer: (B)

The concept being tested is matching a health-related fitness component with a representative activity. Cardiovascular endurance is the body's ability to sustain efficient heart and lung function during extended activity. Jogging or running is the classic example because it keeps the heart rate elevated over a period of time, training the aerobic system and improving how effectively oxygen is delivered to working muscles.

Stretching routines align with flexibility, not body composition, so pairing flexibility with high-intensity training isn’t the most representative match. High-intensity training can improve cardiovascular fitness or muscular power, but it doesn’t illustrate flexibility as clearly. A one-rep max test gauges maximal muscular strength, not muscular endurance, which is better tested by activities requiring repeated contractions over time.
