A: Break Bones

KIDS WHO EXERCISE ARE LESS LIKELY TO BREAK BONES LATER IN LIFE: New research finds that childhood exercise not only curbs obesity, but helps strengthen bones. To find this, Swedish researchers tracked over 800 boy and girls between the ages of seven and nine years old. The participants had to complete 40-minutes of physical activity each day during school. The scientists monitored the children’s skeletal development and compared it to the results of a control group of kids who only did 60-minutes of physical activity per week. The doctors found that those who exercised 40 minutes each day had only 72 fractures while the control group had 143 fractures. The daily-exercisers also had higher bone density in the spine compared to the control group. Scientists say bone-density is an indicator of bone strength, and that the strength remains in the bones later in life. (Time)
