Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Interval training is superior to continuous training for improving glycemic control, hereunder glycemic variability and -spikes. However, the underlying mechanisms and the clinical impact is at present unknown.

The overall objective of this project is to determine the mechanisms underlying aeroic interval-training-induced reductions in glycemic variability and -spikes, and the impact on levels of systemic inflammation in type 2 diabetes patients. It is hypothesized that aerobic interval training reduces glycemic variability and -spikes more than continuous training due to larger improvements in both peripheral insulin sensitivity and the mass action effect of glucose. Moreover, it is hypothesized that these reductions in glycemic variability and -spikes also reduces systemic inflammation.

Control

Control intervention: Subjects will continue their life unaltered during the 14 days intervention period

Group Type EXPERIMENTAL

Control

Intervention Type BEHAVIORAL

Continuous walking

Training intervention: Subjects will perform continuous walking for one hour per day at every weekday during the 14 days intervention period

Group Type EXPERIMENTAL

Continuous walking

Intervention Type BEHAVIORAL

Interval Walking

Training intervention: Subjects will perform interval walking for one hour per day at every weekday during the 14 days intervention period. Interval walking will be performed as repeated cycles of three minutes of slow and hree minutes of fast walking during the entire training session
