Many High School Students Not Getting Exercise They Need

Comstock/Thinkstock(WASHINGTON) -- Many U.S. high school students are not getting the amount of physical activity they need, according to a survey released Thursday by the Centers for Disease Control and Prevention (CDC).

The CDC says youth should be physically active for at least one hour each day and should engage in activities that build muscle for a minimum of three days a week.

But the 2010 National Youth Physical Activity and Nutrition Survey found that only 15.3 percent of the teenagers questioned met the aerobic activity suggestion, while 51 percent met the muscle-strengthening one.  When both activities were combined, only 12.2 percent of the students met the objectives.

Furthermore, the survey found that fewer female students, upperclassmen, and students with obesity fulfilled the recommendations.

Active Girls Twice as Likely to Experience Stress Fractures

Stockbyte/Thinkstock(BOSTON) -- Young girls who participate in physical activities for several hours a week are twice as likely to suffer from a stress fracture than girls who do not, according to a study published Monday in the Archives of Pediatric and Adolescent Medicine.

Researchers at Brigham and Women’s Hospital followed 6,800 adolescent girls for seven years and found that those who were physically active for eight or more hours a week were more likely to develop the injury.  The increased risk for stress fractures was specifically associated with running, basketball, cheerleading and gymnastics.

The study also found that young girls with a history of osteoporosis in their family were almost twice as likely to develop a stress fracture, putting them at an even higher risk if they also engage in the specified sports.  These girls are advised to lower their fracture risk by incorporating more lower-impact activities into their weekly routines.
