Selected blood parameters during recovery from strenuous running exertion in trotters.

The research study examines the impact of strenuous running exertion on certain blood parameters in trotters, and how these parameters recover following exertion. It highlights that all parameters except protein concentration returned to normal levels within 120 minutes of exercise cessation, suggesting a rest period of at least 2 hours between races.

Study Design and Participants

• Researchers undertook the study on 10 trotters engaged in training.
• The assessment involved a strenuous exercise – running at 80% of maximum capability.
• Blood samples were taken from the vena jugularis before and after the running exertion, as well as during the recovery period.

Parameters Measured

• The study measured several blood parameters, including lactic acid concentration, pH-value, haematocrit, haemoglobin content, protein concentration, and osmolality.
• Of these, only the pattern of protein concentration changes could not be adequately captured using simple mathematical models such as bi-exponential or exponential equations.

Findings and Recommendations

• The study found that the basal value of blood lactate concentration was not achieved until 120 minutes post-exercise.
• In contrast, equilibrium for the other parameters was restored much earlier during the recovery period.
• Based on these findings, the researchers suggest a rest period of at least 2 hours between two races, in cases where preliminary heats and finals are scheduled on the same day.
