Why the study?

The acute cardiac stress following high-intensity interval training in patients with type 2 diabetes compared to healthy controls was unknown.

Does one session of high intensity interval training induce different acute cardiac stress responses in patients with type 2 diabetes compared to healthy controls?

Population

Patients with type 2 diabetes and healthy controls

Comparison

Patients with type 2 diabetes vs healthy controls after one session of high intensity interval training

Design

Pilot study

Follow-up

24h post exercise

Overview

Single HIIT session induces similar acute cardiac changes in T2D and controls; pilot data leave open questions on repeated exposure.

Structured PICO

Does one session of high intensity interval training induce different acute cardiac stress responses in patients with type 2 diabetes compared to healthy controls?

P
Population
Patients with type 2 diabetes (T2D) and healthy controls.
I
Intervention
One session of high intensity interval training (4x4 minutes intervals at 90-95% of maximal heart rate) followed by a ramp protocol to peak oxygen uptake (VO2peak).
C
Comparator
Healthy controls undergoing the exact same exercise protocol.
O
Outcome
Acute cardiac alterations measured by echocardiography (30 minutes post-exercise) and Holter electrocardiogram (24h pre-exercise, during, and 24h post-exercise).surrogate

A single session of high-intensity interval training induces similar acute echocardiographic changes in both T2D patients and healthy controls, suggesting no differential acute cardiac stress response.
