Table 7 Analysis of the difference of percentage volume (vol%) between F/NF at the start (t0) and MI (t1, t2) for total, lean and adipose tissue compartments

From: Characteristics, changes and influence of body composition during a 4486 km transcontinental ultramarathon: results from the Transeurope Footrace mobile whole body MRI-project

 

t0: nF= 12, nNF= 10

t1: nF= 12, nNF= 8

t2: nF= 12, nNF= 6

  1. amean differences between finishers and non-finishers are significant. t0: at start of TEFR09, t1: stage 5 to 12 (317–789 km), t2: stage 15 to 24 (1,003 to 1,635 km). F, finishers; ITT, t-test for independent samples; MI, magnetic imaging; NF, non-finishers; SAST, somatic adipose soft tissue; SLT, somatic lean tissue; TAT, total adipose tissue; TERF09, Transeurope Footrace 2009; TLT, total lean tissue; TSV, total somatic volume; TVV, total visceral volume; VAT, visceral adipose tissue; VLT, visceral lean tissue.
  2. Bold numbers mark significant P-values.
