Studies on the effect of Schisandra chinensis extract on horses submitted to exercise and maximum effort

The effect of the berries Schisundru chinensis extract on polo and race horses was studied. The concentration 

of plasmatic lactate and glucose as well as the respiratory and heart rates of these horses submitted to daerent 

physical effort were examined. Thirty adult horses were used for this experiment; 20 polo horses and 10 race horses. 

Ten polo horses were submitted to a 12 min gallop at a speed of 400 m/min, and 10 other polo horses to a 5 min gal

lop at a speed of 700 m/min. The race horses were submitted to a single run on a fixed distance of 800111 at maximum 

speed. Blood jugular samples from each polo horse (when they were in the stable) were collected for lactate and 

glucose analysis before the exercise and at 10 and 50 min after the exercise. Heart and respiratory rates were 

recorded. First each horse was given a single dose of 500 mL of saline half an hour before the race. 


A week later the same horses were given a single dose of 48 g of Schizundru chinemis berry extract. Treated 

polo horses showed a lower increase in heart rate at all moments of the exercise. They also showed a quicker 

recovery of respiratory frequency at the moments immediately after the race (time 0) and 5 min after the same 

race. The performance of the race horses was improved. In polo horses administration of Schizundru extract led 

to a significant reduction of the concentration of plasmatic lactate at 10, and 50min after exercise. Plasma 

glucose concentration in polo horses showed no significant difference between the saline treated and the 

Schizandru -treated animals (with the exception at 50 min after the race).
