Heart _Frequencies and Substrate Concentrations in the Blood o/ Horses during Training in Mexico City (2250 m Above Sea Level) Summary. Measurements of heart frequency during training, and of glucose, lactate, free fatty acids, glycerine, and triglyceride levels in the blood after training were made in horses in Mexico City (2250 m above sea level) over a period of 18 days:

1. In jumping horses heart frequencies of over 200/rain were reached--simultaneously measured frequencies of riders did not exceed 140/rain. During the period observed the heart frequencies remained roughly identical under increased stress, a result of adaptation to high altitude.

2. The blood lactate levels showed no changes during training, despite increased training intensity. This is made possible by successful adaptation of metabolism.

3. The behavior of free fatty acids, triglycerides and glycerine in the blood may be a result of increased utilisation of carbohydrate metabolites (glucose, lactate, pyruvate) and a decreased oxydation of fatty acids, which is favorable energetically.
