  1. a Participants could report more then one injury or illness. Only injuries and illnesses that the participant attributed to exercise (little, moderately, quite a bit, or entirely) are reported. Excluded from the table are injuries and illnesses that the participant's indicated were "not at all" caused by their participation in exercise.
  2. c Injuries/illnesses that afflicted less than 1% of the study population included cardiovascular, headaches, arthritis, mental health conditions, dental, endocrinology, infections, sore muscles, asthma, anemia, and cancer.
