“To our knowledge, this is the first concerted effort to develop a specialized type of contractile activity focused on optimizing human metabolic processes.”
When SPU was tested, the overall effects on blood chemistry included a 52% improvement in blood glucose (sugar) excursion and a 60% reduction in insulin need three hours after consuming a glucose drink.

It doesn’t mean you don’t need to exercise.
Briefly, “While sitting with feet flat on the ground and muscles relaxed, the heel is raised while the forefoot remains stationary. When the heel reaches the top of its range of motion, the foot passively releases.” to go back down. The goal is to simultaneously shorten the calf muscle while the soleus is naturally activated by its motor neurons,” the study suggests. However, this does not mean that he does not need to move a lot or exercise.
The researchers are keen to clarify that this is not the latest advice on diet or exercise. It is a strong physiological action that takes advantage of the distinctive qualities of the soleus.
Summary:
Slow oxidative muscle, most notably the soleus, is inherently well equipped with the molecular machinery to regulate blood-borne substrates. However, all human musculature accounts for only ~15% of the body’s oxidative glucose metabolism in resting energy expenditure, despite being the largest lean tissue mass in the body. We found that human soleus muscle could elevate local oxidative metabolism to high levels for hours without fatigue, during a predominantly soleus type of activity while seated, even in unfit volunteers. Muscle biopsies revealed that there was minimal use of glycogen. Increasing otherwise negligible local energy expenditure with isolated contractions improved systemic VLDL glucose and triglyceride homeostasis to a great extent, e.g. . Targeting a small oxidative muscle mass (∼1% of body mass) with local contractile activity is a powerful method of improving systemic metabolic regulation while prolonging the benefits of oxidative metabolism.
