Values are expressed as mean ± standard deviation (SD). BMI = Body mass index; PWC80% = Physical Work Capacity at 80% of HRmax (208 − 0.7 ∗ age in years) in watts/kg bodyweight. Clusters were based on: age, body composition (trunk fat percentage) and fitness level (PWC80%). * = Significant differences between clusters (p ≤ 0.05, Kruskal-Wallis test). A = Different to CLUSTER A; B = Different to CLUSTER B; C = Different to CLUSTER C; D = Different to CLUSTER D.
