Nonexercising muscle may aid lactate clearance during unilateral exercise; Level 5 data leave open relevance to bilateral activity or patients.
Does physical exertion alter substrate utilization in nonexercising leg tissues in healthy subjects?
Physical exertion causes nonexercising muscle to increase blood flow, oxygen uptake, and carbohydrate utilization, playing an important role in lactate removal.
Ahlborg et al. (1975) studied this question.
