The Effect of a Circuit Resistance Activity Session with Different Intensities on the Levels of Sphingosine one Phosphate in Plasma, Red Blood cells, Platelets and HDL in Young Men.

The role of fats as a source of energy at low and moderate intensities is well known. Physical activity can affect non-triglyceride metabolism such as sphingolipids. Considering the spread of metabolic diseases and the role of sphingolipid metabolites and enzymes related to them, investigating the effect of sports activities on the production of sphingolipids can be a special treatment strategy for these complications. This study was conducted to investigate the effect of two different intensities of circuit resistance training on plasma S1P, red blood cell, and platelet and HDL levels in young men. The statistical population of the present study were young male students aged 19-22, non-athletes. The one-session activity instruction included three consecutive rounds of circuit resistance training at 10 stations. Considering the effect of intensity and duration of activity on the amount of stimulation and duration of release of sphingolipids from production sources, especially red blood cells, the variables were measured in 3 time intervals: before, immediately after, and 24 hours after training. HPLC method was used to measure the samples. Normal data were analyzed using the analysis of variance test for repeated measures at the significance level of p < 0.05. The results showed that the interaction between training groups and measurement times was not statistically significant. The amount of erythrocyte s1p changed significantly during the measurement times (p = 0.018). S1p levels in platelets, erythrocytes, and HDL did not show any significant effect at the measurement times. In both training groups, platelet s1p levels increased after training. In the 20% training group, the amount of s1p HDL increased after training. This increasing trend continued until 24 hours after training. Circuit-type resistance training will be effective in changing the levels of sphingolipids in plasma and their production sources.
