Associations of change in YKL-40 with pre-marathon level of resistin and change in resistin.

<p>Marathon induced change in YKL-40 was positively correlated with pre-marathon level of resistin, i.e. high baseline resistin predicted large increase in YKL-40 levels after the marathon (a). Change in YKL-40 level was also positively correlated with change in resistin concentration (b). Pearson or Spearman correlation analyses were used where appropriate, n = 46.</p

MMP-3, YKL-40 and COMP as a measure of cartilage metabolism before and after the marathon.

<p>Horizontal solid and dashed bars within boxes represent median and mean, respectively, boxes represent interquartile range and lines outside boxes represent minimum and maximum. Outliers are indicated. Paired t-test or Wilcoxońs test was used where appropriate. ***  =  p<0.001, n = 46.</p

Associations of change in MMP-3 level with marathon time and change in resistin concentration.

<p>Marathon induced change in MMP-3 level was negatively correlated with marathon time (a), i.e. the faster the marathon was run the more MMP-3 level increased due to the marathon. Change in MMP-3 level correlated positively with change in resistin concentration (b). Pearson or Spearman correlation analyses were used where appropriate, n = 46.</p

Adipokine levels before and after the marathon race.

<p>Horizontal solid and dashed bars within the boxes represent median and mean, respectively, boxes represent interquartile range and lines outside boxes represent minimum and maximum. Outliers are indicated. Paired t-test or Wilcoxońs test was used where appropriate. ***  =  p<0.001, n = 46.</p
