Vocal warm up consists of a series of body, breathing, and vocal exercises to heat the vocal folds and the muscles involved in breathing, articulation and resonance before more intense activity to prevent overloading, misuse or vocal fatigue. Some of the many physiological effects of vocal warm up are increased muscle temperature, blood flow and oxygen delivery, decreased viscosity and vocal fold resistance, a faster oxidative reaction disposal rate, and a reduced risk of muscle damage. From a subjective point of view, after a vocal warm up, voice quality is better, requires less effort, and control and flexibility are increased. Vocal warm up also has a positive effect on people with voice disorders of various etiologies. Although specific exercises in vocal warm up routines often vary, they mainly include body alignment exercises, breathing training, and resonance and phonation exercises. Effective vocal warm up is highly individual because each voice responds differently to distinct lengths of warm up exercises and at different stages of voice development. The main goal of vocal warm up is to contribute to vocal health by avoiding voice misuse, decreasing the risk of vocal fatigue, avoiding unnecessary muscle compensation and increasing voice longevity in voice professionals.
