Measuring oxygen levels during intense squat exercises

Official title: Analysis of Local and Systemic Oxygen Saturation During Monotonous Exercise Using the Example of 'Death by Squats'

Run by Bundeswehr University Munich · NCT06884644 · Data updated 2026-11-12

This study is testing how intense squat exercises affect oxygen levels and fatigue in active individuals to see how hard they can push themselves.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals who are moderately to severely physically active, engaging in at least 2 hours of exercise per week.

Probably not a fit

Patients with acute infections, musculoskeletal injuries, or chronic cardiovascular or pulmonary diseases may not benefit from this study.

What this trial studies

This observational study investigates the effects of a high-intensity squat exercise protocol, termed 'Death by Squats', on oxygen saturation and fatigue levels in participants. A group of 25-30 moderately to severely physically active individuals will perform bodyweight squats until maximum exertion, while their heart rate and muscle oxygen saturation are monitored. Blood lactate levels will be measured at rest and peak exertion, and participants will report their perceived exertion and reasons for stopping the exercise. The study aims to gather data from April 2023 to December 2024.

Why it matters

Potential benefit: If successful, this study could enhance understanding of muscle oxygenation and fatigue during high-intensity exercise, potentially informing training and rehabilitation protocols.

How similar studies have gone: While similar studies on exercise physiology exist, this specific approach to measuring local and systemic oxygen saturation during a unique squat protocol is relatively novel.
