The Effect of Moderate Exercise on Blood Viscosity and Other Hemodynamic Parameters in Youths

Exercise, in the long run, among other healthy lifestyle interventions, has been shown to improve blood fluidity, cardiovascular risk, and risk for developing metabolic diseases in adults.  Conversely, immediate exercise-induced impairments of blood viscosity are often experienced due to dehydration, stress, and oxygen demand, among other factors.  Young people and adults may experience similar short-term changes in blood flow as a result of submaximal aerobic exercise, according to a 2013 study published by a team of researchers in Valencia, Spain. While previous studies have demonstrated exercise-related impairments of blood fluidity in adults, not much was known about its effects in younger populations.  Romagnoli et al. demonstrated significant increases in hematocrit (p < 0.05) and plasma viscosity (p < 0.05) in 10 young subjects (aged 12-16 years) after 1 hour of submaximal aerobic exercise.  It is likely that young people, like adults, will receive long-term improvements in blood viscosity as a result of regular exercise.
