Are Weights Safe for Kids? New Resource from the AAP Helps Answer Parents' Questions About Injury Prevention and Strength Training at Home

11/28/2012 IronKids App Features Leading Sports Medicine Physician’s IronStrength Workout for Kids Ages 8 and Up

More than 30 million kids and teens play sports in the United States. According to the    U.S. Consumer Product Safety Commission, more than 3.5 million sports-related injuries to children under age 15 are treated each year, with injuries from football, basketball, baseball and soccer topping the list. The American Academy of Pediatrics (AAP) recommends strength training for kids ages 8 and older as a safe and effective means of both injury reduction and performance enhancement.

To give families the tools they need to strength train safely and effectively, the AAP has released the IronKids app, which includes everything a young athlete needs to safely build strength, balance and fitness, and to prepare to excel in sports and keep playing by preventing injury. The app features a 45-minute workout led by Jordan D. Metzl, MD, FAAP, a nationally recognized sports medicine pediatrician, 29-time marathon runner, and 9-time Ironman triathlete. It includes detailed demonstrations to work the core, upper body and lower body, as well as strength-training pointers and tools to create custom workouts and set goals and reminders.
The app contains the full workout and the principles and tips clips from Dr. Metzl’s DVD, Home Strength Training for Young Athletes, recently released by the AAP, as well as tools to create custom workouts by selecting, naming and scheduling exercises.

The app is available through the iTunes store for iPhone/iPad/iTouch.

Dr. Metzl developed this home strength-training tool for the AAP in response to the widespread recognition in the medical community of the benefits of strength training and injury prevention for children, and the lack of resources for parents, coaches and kids to strength train at home or on the field.

Parents think that strength training is dangerous for kids, that it stunts growth and requires the help of a professional trainer – but these assumptions are untrue,” said Dr. Metzl, who practices sports medicine at the Hospital for Special Surgery in New York. “Strength training is different from power lifting, and it is safe for kids starting at 8 years old. Because of these misconceptions and the lack of resources available for strength training, most kids just don’t do it. That is part of the reason we’re seeing so many injuries in youth sports – kids’ bodies aren’t prepared."

Dr. Metzl adds, “We developed a home strength training program that kids and parents can conveniently do together, and that coaches can use on the field or in the gym. We also are encouraging physicians nationwide to discuss the benefits of strength training with their patients.”
