High-intensity resistance exercise is not as effective as traditional high-intensity interval exercise for increasing the cardiorespiratory response and energy expenditure in recreationally active subjects

Abstract

Purpose Traditional high-intensity interval exercise (HIIE) highly stimulates the cardiorespiratory system and increases energy expenditure (EE) during exercise. High-intensity resistance exercise (HIRE) has become more popular in recreationally active subjects. The physiological responses to HIRE performed with light or moderate load is currently largely unknown. Here, we examined the effect of the type of interval exercise [HIRE at 40% (HIRE40) and 60% (HIRE60) 1-RM vs. traditional HIIE] on the cardiorespiratory response and EE during and after exercise. Methods Fifteen recreationally active adults randomly completed traditional HIIE on an ergocyle, HIRE40 and HIRE60. The sessions consisted of two sets of ten 30-s intervals (power at 100% VO2max during HIIE; maximal number of repetitions for 10 different free-weight exercises during HIRE40 and HIRE60) separated by 30-s active recovery periods. Gas exchange, heart rate (HR) and EE were assessed during and after exercise. Results VO2mean, VO2peak, HRmean, the time spent above 90% VO2max and HRmax, and aerobic EE were lower in both HIRE sessions compared with HIIE (P < 0.05). Anaerobic glycolytic contribution to total exercise EE was higher in HIRE40 and HIRE60 compared with HIIE (P < 0.001). EE from excess post-exercise oxygen consumption (EPOC) was similar after the three sessions. Overall, similar cardiorespiratory responses and EE were found in HIRE40 and HIRE60. Conclusions HIRE is not as effective as HIIE for increasing the cardiorespiratory response and EE during exercise, while EPOC remains similar in HIRE and HIIE. These parameters are not substantially different between HIRE40 and HIRE60.

Resistive exercise training as an effective method to maintain lung function and functional capacity

“…It is known that the population present in gyms is young, healthy, and the overwhelming majority is unaware of the real benefits of a routine of physical activity on lung function [11]. The people who frequent these spaces do not imagine that moderate to high intensity resistance training not only promotes body weight control, but also exercises influence on the cardiovascular demands [12]. According to Tiler et al [13], upper and lower limb exercises performed in healthy individuals usually generate neurological stimuli capable of influencing ventilatory mechanics, and thus promote greater chest expansion, lower respiratory rate during exercise and greater oxygen uptake.…”

Acute effects of resistance-type and cycling-type high-intensity interval training on arterial stiffness, cardiac autonomic modulation and cardiac biomarkers

“…Therefore, the intensity of R-HIIT and C-HIIT was considered to be the same. This method has been used by other researchers [17,18].…”

“…To address this limitation, our study will use the rating of perceived exertion (RPE) method to ensure that the intensity of the two HIIT modes is matched. This method has been successfully used by Rønnestad and Järvinen in previous studies [17,18].…”
