Cardiopulmonary Fitness, Physical Activity Patterns, and Selected Coronary Risk Factor Variables in 11- to 16-Year-Olds.

The peak oxygen uptake (VO) of 199 boys and 164 girls (mean age 13.2±1.3 yrs) was examined in relation to their body fatness, blood pressure, and serum cholesterol level.

Peak Oxygen Uptake and Physical Activity in 11- to 16-Year-Olds.

The present study examined the relationship between peak V̇O₂ and habitual physical activity in 11- to 16-year-old students. The peak V̇O₂ of 111 girls and 85 boys was determined using treadmill or cycle ergometry. Habitual physical activity was estimated from minute-by-minute heart rate monitoring over three 12-hr periods during normal school days.
