THE RELATIONSHIP OF HEART RATE AND LACTATE TO CUMULATIVE MUSCLE FATIGUE DURING RECREATIONAL ALPINE SKIING.

The article reports on the results of research which was conducted to investigate the relationship between heart rate, lactate and common fatigue indices during downhill skiing. Researchers evaluated ten healthy female recreational skiers who skied for 3 hours under standardized conditions. They found that blood lactate is a practical marker of chronic stress which can be a predictor of fatigue in downhill skiers.
