Table 1.
Demographic data on the 46 male marathoners participating in the study.
Figure 1.
Adipokine levels before and after the marathon race.
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.
Figure 2.
MMP-3, YKL-40 and COMP as a measure of cartilage metabolism before and after the marathon.
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.
Figure 3.
Associations of change in MMP-3 level with marathon time and change in resistin concentration.
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.
Figure 4.
Associations of change in YKL-40 with pre-marathon level of resistin and change in resistin.
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.
