The relationship between attention deficit hyperactivity disorder and health-related physical fitness in university students

College students with a tendency toward attention deficit/hyperactivity disorder (ADHD) tend to act impulsively because they cannot control their behavior. They display low academic achievement and insufficient social skills, and are at high risk for alcoholism and drug abuse. Although various intervention methods have been used to reduce ADHD tendency (e.g., improving physical fitness and participating in sports and exercise), there are few studies on the relationship between ADHD and health-related physical fitness. Accordingly, this study explored the relationship between ADHD symptoms in college students and physical fitness. We measured health-related physical fitness and ADHD in 86 male college students using a self-report rating scale. The results showed the following. First, a significant relationship was found between ADHD tendency and inattention/memory problems, hyperactivity/restlessness, impulsivity/emotional lability, and abdominal fat. Push-ups were associated with ADHD tendency and the inattention/memory problems, hyperactivity/restlessness, impulsivity/emotional lability, and problems with self-concept subtests. Grip strength was significantly related to inattention/memory problems. Second, risk factors for ADHD tendency significantly increased for male college students with low muscular strength and endurance relative to those with greater muscular strength and endurance. Risk factors also significantly increased for male college students with high rates of abdominal obesity.
