The Claim

The hybrid training system (HTS) increases the metabolic intensity of supine knee bending exercise to approximately 2.4 METs.

In plain English

Supine knee bending performed with a hybrid training system results in a metabolic intensity of 2.4 METs, which is similar to the energy expenditure of light housework.

See the scientific wording

Hybrid training system (HTS) increases metabolic intensity of supine knee bending exercise to approximately 2.4 METs, which is equivalent to light housework and may be feasible for bedridden patients unable to perform higher-intensity activities.

Why this might work

When a person bends their knee while lying down and electrical pulses are timed to match the movement, the muscles are forced to contract harder than they would on their own. This extra force stretches the muscles while they are active, making them work much harder and use more oxygen. The heart beats faster to deliver more oxygen to the muscles, and the body burns more energy, reaching the same intensity as light housework.

  1. Study: Low‐volume resistance exercise attenuates the decline in strength and muscle mass associated with immobilization

    The study found that doing knee bends while lying in bed, with a little electrical help, makes your body work about as hard as doing light housework—like folding laundry—without making you feel more tired. This means it could be a good exercise for people who are stuck in bed.
