The Role of Moderate Aerobic Exercise as Determined by Cardiopulmonary Exercise Testing in ALS

Table 5

Correlations between ALSFRS-R total score and CPET variables on the peak of effort at T2.

CPET variables (L/min)	ALSFRS- R total score in T2
	Pearson correlation	Sig. (2-tailed)
METS	0.491
RCP	0.256	0.239
VCO2	0.580
VE	0.585
	0.544

ALSFRS-R (ALS functional scale revised), METs (metabolic equivalent), VCO2 (carbon dioxide output), RCP (respiratory compensation point), VO2 peak (oxygen uptake peak), and VE (minute ventilation) expressed in L/min. Significant results (p ≤ 0.05) are represented in bold.
