K4b2 Validity and Reliability during Fast Outdoor Running

Published: 06 February 2012

A new validation study of K4b2 was presented during last ACSM show assessing both the validity and reliability of the system.

19 Caucasian endurance trained individuals and 30 adolescents from a rural primary school in Kenya completed maximal incremental running tests with COSMED K4b2. The Douglas bag method (DB) was used as the criterion for comparison.

The study conclusion was that "K4b2 device proved valid and reliable for VO2 during submaximal and maximal running velocities outdoors".
