Biochemical and physiological changes in football players
The Medical Journal of Australia
|May 2, 1981
Summary
Football players experienced dehydration and increased body temperature during intermittent exertion. Biochemical changes, including acidosis and elevated enzymes, were observed but were less severe than in marathon runners.
Area of Science:
- Sports Medicine
- Exercise Physiology
- Biochemistry
Background:
- Intermittent high-intensity exertion in football differs significantly from endurance running.
- Understanding physiological responses to football matches is crucial for athlete health and performance.
Purpose of the Study:
- To compare the biochemical and physiological changes in football players after a match with those reported in marathon runners.
- To investigate the effects of intermittent exertion on hydration status, body temperature, and serum markers in athletes.
Main Methods:
- Studied 23 football players before and after a competitive match.
- Monitored fluid deficit, body temperature, and analyzed serum levels of various biochemical markers.
- Compared findings with established data from marathon runner studies.
Main Results:
- All players exhibited significant fluid deficit and increased body temperature.
- Biochemical changes included acidosis, elevated creatinine, urate, urea, and creatine kinase.
- Serum magnesium and potassium levels decreased, contrasting with hyperkalemia often seen in runners.
Conclusions:
- Intermittent exertion in football causes distinct physiological and biochemical alterations.
- While some changes overlap with endurance athletes, key differences exist, particularly in electrolyte balance.
- These findings highlight the unique physiological demands of football and inform athlete management strategies.
