11th Grade Physical Health

By 11th grade, most children are nearing the end of puberty and completing the process of maturing into adults. Although they will continue to grow and mature for a couple more years, they are now young adults. Eleventh graders are usually 16 or 17 years old, and the information in this section covers adolescents in the typical age group. However, the age at which young people reach milestones for physical growth varies considerably. Keep in mind that the information here is intended only as a general guide. If you are concerned that your teenager’s physical development is out of step with others in her age group, you should consult your pediatrician or family physician.

Overview

Engaging in regular physical activity and exercise is essential for adolescents and young adults. It promotes growth, helps build strength and develop healthy bodies, and can even enhance academic performance. Regular physical activity also reduces the risk of obesity and chronic diseases, such as diabetes, hypertension, heart disease, and certain cancers. Many children become less physically active with the onset of puberty, increasing their risk of developing conditions such as diabetes and obesity. Regular physical activity and exercise can help adolescents feel in control of their bodies and can also be a helpful way of dealing with the stress and emotional changes that occur during puberty.  

Benefits

The benefits of physical activity can include:

  • Improved mood
  • Better sleep
  • Weight management
  • Stress management
  • Improved social skills
  • Increased self-sufficiency and self-confidence
  • Improvements in learning
  • Decreased television, video game, cellphone, and computer use
Recommendations

The US Department of Health and Human Services recommends that children and adolescents participate in at least 60 minutes of vigorous or moderate-intensity physical activity each day. This does not need to be 60 minutes of sustained activity at a time, but can include different episodes of activity that, together, total 60 minutes or more. Adolescents should take part in a variety of activities that require different degrees of exertion. These should include vigorous activities, such as running, and more moderate activities, such as brisk walking.

Maintaining Healthy Habits

The proportion of young people who meet the recommended guidelines for physical activity declines as children age, and adolescents are often likely to become less active as they get older. This decline comes just as maintaining a healthy level of physical activity becomes more important than ever, as children mature into their adult bodies. Research has found that the number of fat cells in our bodies is set during adolescence, and although these cells can shrink or expand later in life, they cannot be eliminated. Establishing and maintaining healthy physical activity habits at this age will help set adolescent bodies on a path to lifelong fitness and wellbeing.

Vigorous Physical Activity

The guidelines recommend that children and adolescents engage in vigorous physical activity at least three times a week. This can include shooting baskets, running, or riding a bike.

11TH GRADE PHYSICAL HEALTH TIPS

By 11th grade, most children are nearing the end of puberty and completing the process of maturing into adults. Engaging in regular physical activity and exercise is essential for adolescents and young adults.

Building Muscle

Building muscle strength is especially important for children and adolescents, and exercise is essential to achieving this goal. Muscle-strengthening activities are those that force the muscles to do more than the normal workload and should include all the major muscle groups of the body. Examples of muscle-strengthening activities include climbing, sit-ups, and resistance exercises. The guidelines recommend that children and adolescents engage in muscle-strengthening activities at least three times a week. 

Bone Mass

Adolescence is a crucial time for building bone mass, up to a quarter of which is formed during the adolescent growth spurt, from around the age of 9 until the end of puberty. Bone-strengthening exercises build strength through the force that is exerted on the bones. Activities that achieve this important goal include jumping, running, skipping rope, and playing tennis or volleyball. The guidelines recommend that adolescents engage in bone-strengthening activities at least three times a week.

Sleep Overview

Though your child's schedule may become more hectic as your child continues through high school, it is important for their to continue to prioritize sleep. Experts stress that adequate sleep is as important to a healthy lifestyle as a balanced diet and physical activity. Due to the biological changes that occur during puberty, a teenager's natural sleeping pattern typically shifts backwards, causing them to not feel tired until later in the evening. Some adolescents are unable to fall asleep before 11 PM. This lack of sleep can negatively affect both a student’s academic and sports performance, by limiting their ability to concentrate and increasing their likelihood of sustaining an injury. If you notice significant changes in your child’s sleeping habits, it may be a sign that other health-related issues are present. Consult with your child’s health care provider about steps you can take to ensure your child gets a more restful night of sleep.  

Nightly Sleep Needs

Sleep needs do not drop significantly as your child matures even though their schedule may become tighter. Experts recommend that high school students sleep for about 9 hours and 15 minutes each evening so that they are able to function at their best. To achieve this goal, a student who needs to be up by 6:15 AM to get ready for school should be in bed no later than 9 PM. Though a 9 PM bedtime may seem unattainable to some, experts recommend making sleep a priority by encouraging your child to get as much sleep as possible.  The closer they are to getting the recommended amount of sleep, the better.
