A 10-minute cycling workout with two 20-second all-out sprints likely improves next-day blood sugar control in men with type 2 diabetes.
See the scientific wording
In men with type 2 diabetes, a 10-minute REHIT session consisting of two 20-second all-out cycling sprints (total 40 seconds of high-intensity cycling) likely produces acute improvements in 24-hour glycaemic control; the magnitude of improvement is not reported, and the evidence is based on a randomized crossover trial of 11 men.

Supported1 studyA REHIT session lasts 10 minutes.
Supported1 studyA REHIT session consists of two 20-second all-out cycling sprints.
Supported1 studyA REHIT session offers a time-efficient exercise option for those who report lack of time as a barrier to regular exercise.
Not testedNo studies
Evidence is judged against each part on its own, so a study that tests one part never counts as a verdict on the whole claim.
What the research says

Extremely short duration interval exercise improves 24-h glycaemia in men with type 2 diabetes
Randomized Controlled TrialHuman2018
The randomized crossover trial showed that a 10-minute REHIT session with only 40 seconds of hard cycling significantly lowered 24-hour mean glucose and time in hyperglycaemia, supporting the claim that this very short protocol can acutely improve glycaemic control.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Hard cycling makes your muscles work very hard. This uses up their stored sugar and flips a switch inside the muscle cells called AMPK. That switch moves sugar doors (GLUT4) to the cell surface. With these doors open, sugar leaves the blood and enters the muscles without needing insulin. The muscles also refill their sugar stores for hours afterward, pulling more sugar out of the blood. This lowers blood sugar for the rest of the day.

A 10-minute cycling workout with two 20-second all-out sprints likely improves next-day blood sugar control in men with type 2 diabetes.
Mechanism
1 studyHard cycling makes muscles use up their sugar and turn on a sugar-uptake switch. This switch opens sugar doors on the muscle cells, so sugar moves out of the blood and into the muscles without insulin. The muscles keep pulling sugar from the blood for hours to refill their stores, which brings blood sugar down for the rest of the day.

This lowers blood sugar for the rest of the day.
Two 20-second all-out cycling sprints cause forceful, repeated contraction of large skeletal muscle groups, rapidly consuming ATP and generating AMP.
The rise in AMP activates AMP-activated protein kinase (AMPK) in the contracting muscle fibers.
Activated AMPK triggers translocation of GLUT4 glucose transporters from intracellular vesicles to the muscle cell membrane.
GLUT4 at the membrane increases insulin-independent glucose uptake from the blood into skeletal muscle.
The intense contractions deplete muscle glycogen stores, creating a strong drive for glycogen resynthesis during recovery.
During the 24-hour recovery period, muscle cells continue to take up glucose from the blood to replenish glycogen, lowering circulating glucose concentrations.
Post-exercise enhancement of insulin signaling in skeletal muscle further increases glucose disposal, improving glycaemic control over the following day.
