Effects of High-Intensity Training on Anaerobic and Aerobic Contributions to Total Energy Release During Repeated Supramaximal Exercise in Obese Adults

Abstract

BackgroundStudying relative anaerobic and aerobic metabolism contributions to total energy release during exercise may be valuable in understanding exercise energetic demands and the energetic adaptations that occur in response to acute or chronic exercise in obese adults. The aim of the present study is to evaluate the effects of 6 weeks of high-intensity training (HIT) on relative anaerobic and aerobic contributions to total energy release and on peak power output during repeated supramaximal cycling exercises (SCE) in obese adults.MethodsTwenty-four obese adults (body mass index = ± 33 kg.m−2) were randomized into a control group (n = 12) and an HIT group (n = 12). Accumulated oxygen deficits (ml.min−1) and anaerobic and aerobic contributions (%) were measured in all groups before and after training via repeated SCE. In addition, the peak power output performed during SCE was determined using the force-velocity test.ResultsBefore HIT, anaerobic contributions to repeated SCE did not differ between the groups and decreased significantly during the third and fourth repetitions. After HIT, anaerobic contributions increased significantly in the HIT group (+11 %, p < 0.01) and were significantly higher than those of the control group (p < 0.01). Moreover, the peak power obtained during SCE increased significantly in the HIT group (+110 W.kg−1, p < 0.01) and correlated positively with increases in anaerobic contributions (r = 0.9, p < 0.01).ConclusionsIn obese adults, HIT increased anaerobic contributions to energy release which were associated with peak power enhancement in response to repeated SCE. Consequently, HIT may be an appropriate approach for improving energy contributions and muscle power among obese adults.

Physiological adaptation following four-weeks of high-intensity functional training

“…These results support the hypothesis that the improvements in the anaerobic performance would occur following the short fourweek intervention. It is well-established that the participation in the HIT-like programming results in the anaerobic im-provements (i.e., peak power and mean power) 15,23 . For instance, the untrained individuals showed improvements in the anaerobic performance (5%-28%) following the HIT training ranging from 2 to 14 weeks 23 .…”

Conversely, a twoweek sprint interval training program in the physically active participants improved the anaerobic performance, which was suggested to happen because of the improved cellular buffering systems 22 .…”

“…Latihan aerobik secara rutin diperlukan untuk menjaga kebugaran seseorang pada usia berapa pun termasuk anak dan usia lanjut (Foster, Wright, Battista, & Porcari, 2007;Gomez-Cabrera, Ferrando, Brioche, Sanchis-Gomar, & Viña, 2013). Latihan untuk menjaga kebugaran kardiorespirasi juga dibutuhkan oleh individu yang memiliki penyakit atau masalah fisiologis tertentu seperti obesitas (Jabbour, Iancu, & Paulin, 2015), penyandang HIV (O'Brien, Tynan, Nixon, & Glazier, 2016), bahkan individu yang mengalami kelumpuhan (Margonato, 2008). Beberapa latihan aerobik yang dapat dengan aman untuk dilakukan terutama oleh individu yang memiliki masalah fisiologis adalah latihan dengan intensitas ringan hingga moderat seperti berjalan kaki, lari kecil atau joging, berenang, bersepeda dan senam aerobik.…”

Can High-Intensity Functional Suspension Training over Eight Weeks Improve Resting Blood Pressure and Quality of Life in Young Adults? A Randomized Controlled Trial

“…Due to difficulties in reproducing the protocol in day-to-day training, different modified Tabata-based protocols were summarized under the title "Tabata-like protocols" [12]. The use of those protocols was found to be effective in well-trained athletes [13,14] in individuals with a sedentary lifestyle [15,16], as well as in top-level athletes [17,18]. Although initially developed in the context of endurance training, the application of "20 seconds loading-10 seconds resting" protocols in strength training also revealed positive effects [19,20].…”
