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