title: Influence of exercise on serum levels of myoglobin measured by radioimmunoassay.
abstract: To determine the influence of exercise on serum levels of myoglobin, serum levels of this protein were determined by RIA in 90 healthy men, divided as follows: (1) Basal control (no exercise) 25 cases; (2) Moderate exercise (after subject had been working for 12 h in Medicine Emergency Service) 19 cases, and (3) Intensive exercise: (a) football professional (45-min match) 10 cases; (b) football amateur (45-min match) 10 cases; (c) basketball professional (45-min match) 10 cases, and (d) basketball professional (90-min training) 16 cases. Our results led us to the following conclusions. (1) Moderate exercise, such as the usual daily work, does not modify myoglobin levels; (2) Myoglobin serum levels after exercise increase in nearly all individuals. They are higher in untrained people; (3) There seems to be a correlation between exercise intensity and increase of myoglobin serum levels, and (4) The detection of serum myoglobin by RIA may have a wide field of application for sport medicine.
