  1. N = 42; fish oil and exergame N = 22 and olive oil and exergame N = 20. Data are median values (interquartile ranges) as indicated. Each listed fatty acid is expressed as their percentage [%] of all the fatty acids (100%) Omega-3 index is defined as the percentage of EPA and DHA in the red cell membrane, with the remaining FA building up to 100% [76]. p-values were calculated using Friedman test. *p < .05
