Key result
Low-volume HIIT and moderate continuous training improve VO2 kinetics during high-intensity exercise in T2D.
Why the study?
Does low-volume HIIT and MICT improve VO2 kinetics during high-intensity exercise in patients with type 2 diabetes?
Does low-volume HIIT and MICT improve VO2 kinetics during high-intensity exercise in patients with type 2 diabetes?
Low-volume HIIT and MICT rapidly improve VO2 kinetics during high-intensity exercise in patients with type 2 diabetes, with benefits maintained over 12 weeks.
May enhance VO2 kinetics in type 2 diabetes; hypothesis-generating and requires larger trials before practice change.
Three weeks of high-intensity interval training and moderate-intensity continuous training decreased the time constant of the primary phase of oxygen uptake (V̇o 2 ) and amplitude of the V̇o 2 slow component during a high-intensity exercise initiated from an elevated baseline, a protocol that mimics the abrupt metabolic transitions akin to those in daily life, in type 2 diabetes. These V̇o 2 kinetics improvements were maintained until the end of the 12-wk intervention without changes in muscle deoxygenation kinetics.

Gildea et al. (2022) studied Type 2 diabetes. High-intensity interval training (HIIT) vs. Moderate-intensity continuous training (MICT) was evaluated on Time constant of the primary phase of oxygen uptake (V̇o2) and amplitude of the V̇o2 slow component. Low-volume high-intensity interval training and moderate-intensity continuous training improved VO2 kinetics during high-intensity exercise in type 2 diabetes, maintained over 12 weeks.
