ABSTRACT
Low-level laser therapy (LLLT) and light-emitting diode therapy
(LEDT) have been used as an important therapeutic approach to
manage pain [1, 2], treat tendinopathies [3], or accelerate tissue
repair [2, 4]. Over the last decade, these therapies using red and/or
infrared wavelengths have been applied to skeletal muscles to
prevent damage, mainly analyzed by creatine kinase (CK) levels in
blood, accelerate muscle recovery after intense exercises, and also
increase muscle performance [5-7].
