Effects of Training With a Pressure Cuff on Cellular Energy Activity

March 26, 2026 updated by: Hannes Bossung, Spital Thurgau AG

Influence of Short-Term Conventional Cuff-Assisted Training on Mitochondrial Capacity: A Non-Invasive Investigation

This study investigates low-load, cuff-assisted training to improve mitochondrial capacity. The intervention is carried out using automated pressure cuffs, applying an individualized pressure of 70% of the limb occlusion pressure. This approach reflects the current scientific consensus for safe and effective use in clinical populations.

Within a rehabilitation setting, two training modalities are compared: intermittent strength training and alternating continuous endurance training. Muscle oxygen saturation is measured non-invasively using near-infrared spectroscopy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
Determination of changes in the mitochondrial capacity of skeletal muscle (of the thigh muscle, vastus lateralis; measured non-invasively)
Time Frame: From enrollment to the end of treatment at 6 weeks.
From enrollment to the end of treatment at 6 weeks.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Minimum and maximum oxygen saturation (SmO₂) during application of pressure cuffs (measured via NIRS)
Time Frame: From enrollment to the end of treatment at 6 weeks.
From enrollment to the end of treatment at 6 weeks.
Changes in total hemoglobin (tHb) as a measure of local blood volume (measured via NIRS)
Time Frame: From enrollment to the end of treatment at 6 weeks.
From enrollment to the end of treatment at 6 weeks.
Assessment of subjective functional mobility using the "Lower Extremity Functional Scale" (LEFS) questionnaire
Time Frame: From enrollment to the end of treatment at 6 weeks.
Maximal Score: 80; Minimal Score: 0; Higher Score indicates better functional mobility
From enrollment to the end of treatment at 6 weeks.
