Physiological Response to Non-Traditional High-Intensity Interval Training

Abstract

High intensity interval training (HIIT) is an exercise program not only for professional athletes, but also for the general population. Usually, one-dimensional modalities such as running or a cycling simulator are used. There also exist protocols that use the HIIT principles but apply full-body exercises (HWT). The purpose of the study was to verify the response to unconventional loads based on HIIT and HWT protocols using the near infrared spectroscopy (NIRS) and spiroergometry: wall ball (WB); SKI ergometer, toes to bar (TTB) and assault air bike (AB) in a selected proband. Working interval was 60 s resp. 30 s, the rest between sites was progressively reduced from 60 s to 30 s. The proband completed a total of 3 laps. The results showed that the load applied had been similar to that of HWT or HIIT, where the effect on cardiorespiratory and metabolic functions was confirmed. Acute changes in the observed parameters of SmO2 in m. vastus lateralis indicate a possible effect on the development of strength capabilities. It has also been confirmed that the application of variable types of load can be applied simultaneously with the adjustment of rest time and thus using conditions that can reflect current options (material, environment, time) and specific goals. The measured values of muscle tissue oxidation, carbon dioxide output, heart rate confirm that a similar type of load can be a suitable means of affecting cardiovascular and metabolic functions.
