Resting Heart Rate. For teenagers (age 13 to 19), a normal resting heart rate is anywhere between 60-100 beats per minute. Because of differences in teens' bodies and physiology, the range for an acceptable resting heart rate is much greater than for other age groups.
Teens need somewhat more calories than when they were a bit younger. Teenage boys on average need 1,800 to 2,600 calories a day if they're 11 to 13 years, and 2,200 to 3,200 calories a day if they're 14 to 18 years of age. Teenage girls need more, too: 1,800 to 2,200 calories a day if they're ages 11 to 13, and 1,800 to 2,400 calories a day if they're age 14 to 18. Gender, body size, growth rate and activity level specifically determine how many calories teens need.
