Exercise Training on Brain Insulin Responsiveness
Effects of One Exercise Training Session on Brain Insulin Responsiveness
University Hospital Tuebingen
40 participants

INTERVENTIONAL
Conditions
Summary
The overarching goal of the current study is to investigate the effect of one acute bout of exercise on the brain insulin responsiveness in a cross-over study design. To this end, investigators will compare the effect of two single endurance exercise sessions with different intensities, namely moderate intensity continuous training (MICT) and high-intensity-interval-training (HIIT), which will be performed in a randomized order. This will be compared to a waiting control condition.

Interventions
the MICT consists of 60 min continuous cycling
HIIT consists of 10-min warm-up at the power output corresponding to 50% peak power output (PPO), 4 x 4-min intervals at a power output corresponding to 75% PPO with a 4-min active resting period at 30% PPO to recover
sitting in a waiting room for 60 min
