The Effect of Age on the V˙O2max Response to High-Intensity Interval Training

Abstract

In healthy individuals with an aerobic capacity typical for what is observed in the population, the training response is likely not affected by age in a short-term training intervention but may rather be affected by the initial training status. These findings imply that individuals across age all have a great potential for cardiovascular improvements, and that HIIT may be used as an excellent strategy for healthy aging.

A comprehensive cardiovascular disease risk profile in patients with schizophrenia

“…Moreover, the format of vigorous physical activity is also of importance. For effective training‐induced stimulation of the heart, the movement should preferably be performed uphill and/or with involvement of a large volume of muscle mass . These elements may not have been well reflected in the physical activity measurements in our study.…”

“…Although encouragement was given to the patients to continue their test to exhaustion, psychological factors may certainly explain their ~10% lower HR peak compared to the healthy references. However, it is possible that their untrained status may have led to a physiological impairment and lower HR peak , as observed with, for example, advancing age . Moreover, it could also be explained by the use of second‐generation antipsychotics, such as clozapine, which increases adrenergic activity and heart rate during rest and may cause autonomous dysregulation .…”

“…16,17 However, the association between physical activity and directly assessed VȮ 2peak can be weak, 18 suggesting its association to CVD risk may be questioned. As the level and format of physical activity is critical for VȮ 2peak alterations, 19,20 simply counting steps per day and minute may not mirror taxation of oxygen transporting organs, and in turn exercise-induced improvements in VȮ 2peak .…”

Entrenamiento De Intervalos De Alta Intensidad (Hiit) en Adultos Mayores: Una Revisión Sistemática

“…Así por ejemplo, se comprobó que el HIIT aplicado durante 4-8 semanas mejora los valores de VO2 máximo entre un 4 y un 15% en sujetos no entrenados y también en personas activas (Sloth, Sloth, Overgaard, & Dalgas, 2013). Del mismo modo, entrenamientos interválicos de una intensidad próxima al 85-95% de la FCM se han mostrado eficaces para mejorar el VO2 máximo en diferentes colectivos, desde personas sanas a personas con determinadas patologías (StØren et al, 2017).…”
