Abstract

DELPRADO-AGUIRRE, Fernando. Exercise physiology in Colombian vocology practice: a necessity. Rev. Investig. Innov. Cienc. Salud [online]. 2020, vol.2, n.2, pp.44-55.  Epub Aug 04, 2021. ISSN 2665-2056.  https://doi.org/10.46634/riics.31.

In recent years, vocology has focused especially in research and clinical application of evidence-based principles that enhance motor learning and motor control related to voice function. The process of voice production occurs due to coordinated action of respiration, phonation and resonance subsystems. Likewise, the function of these subsystems is a result of the activation of a variety of muscles that seem to behave similarly to skeletal limb muscles. Taking this into account, exercise principles that improve strength and endurance of skeletal limb muscles may also be applied to improve performance of voice production. First, this article focuses on functional aspects of muscle tissue; muscle fiber types I and II are described and, in the same way, the distribution of these fibers in voice production muscles is pointed out. Second, physiological adaptations to training (conditioning) as well as detraining from inactivity (deconditioning) are portrayed. Afterwards, progressive resistance training is explained next to its principles and its application to vocology. Finally, the paper argues the necessity of including exercise science into practice and research of vocology in Colombian context, based on some national reports available to date.
