Background: Interleukin (IL)-6, total antioxidant capacity (TAC) and uric acid (UA) increase
after exercise in able-bodied individuals. Wheelchair Basketball Athletes (WBA), having
low muscle mass, could be at risk of post-exercise ketosis.
Objective: This study aimed to evaluate the post-exercise ketosis, IL-6, and antioxidant response,
in WBA of the Italian National team, after a simulated match.
Methods: Dietary intakes, Starvation Symptoms Inventory (SSI), percentage of fat mass (FM%)
and basal Respiratory Exchange Ratio (RER) and Basal Energy Expenditure (BEE), were evaluated.
Salivary TAC, UA and IL-6 were measured: before (PreM), at the end (EM) and 20 minutes after
(PostM) the match. Capillary glucose and β-hydroxybutyrate (βHB) were monitored. Percentage
of Heart Rate Reserve (%HRR) was measured to evaluate exercise intensity.
Results: WBA had low carbohydrates (43.5% of daily energy intake (En)) and high fat (36.3% En)
intakes. The increase in UA at PostM correlated with En (0.810, p<0.01) and was inversely related
to βHB at EM (-0.719, p<0.05). Furthermore, at PostM growing IL-6 levels correlated with BEE
(0.778, p<0.05) and inversely related to FM% (-0.762, p<0.5) were found, which in turn was correlated
to SSI (0.781, p<0.05). Also βHB PostM correlated with SSI (0.761, p<0.05) but was inversely
related to RER (-0.745, p<0.05) and En (-0.826, p<0.01).
Conclusion : Our study suggests that some WBA should improve their dietary habit in order to prevent
post-exercise ketosis and ameliorate the endogenous antioxidant response after exercise
