Perception-Based Methods And Beyond: A Current Opinion On How To Assess Static Stretching Intensity, Konstantin Warneke, Anthony J. Blazevich, Daniel Jochum, David G. Behm, Ewan Thomas, Masatoshi Nakamura, José Afonso

Research outputs 2022 to 2026

Muscle stretching is widely used in clinical, athletic, and otherwise healthy populations, yet a consensual definition of stretch intensity—a key component of stretch load—does not exist. This is important because the effects of stretch intensity on range of motion and strength are controversial but suggested to affect clinical practice and scientific research. Most commonly, stretch intensity is defined in relation to an individual’s perceived level of discomfort or pain; however, these definitions are problematic for several reasons, including that consensual and objective quantifiable definitions of ‘pain’ and ‘discomfort’ do not exist, perceptions vary widely (and may not be sensed in …
