Oxidative Stress Biomarker Responses To an Acute Session of Hypertrophy-Resistance Traditional Interval Training and Circuit Training

Abstract

We have studied circuit resistance schemes with high loads as a time-effective alternative to hypertrophy-traditional resistance training. However, the oxidative stress biomarker responses to high-load circuit training are unknown. The aim of the present study was to compare oxidative stress biomarker response with an acute session of hypertrophy-resistance circuit training and traditional interval training. A week after the 1 repetition maximum (1RM) test, 11 healthy and well-trained male participants completed hypertrophy-resistance acute sessions of traditional interval training (3 × 10 repetitions at 75% of the 1RM, with 90-second passive rest) and circuit training (3 × 10 repetitions at 75% of the 1RM, in alternating performance of 2 exercises with different muscle groups) in a randomized and cross-over design. Venous blood samples were collected before (pre) and 10 minutes after (post) the resistance training sessions for oxidative stress biomarker assays. As expected, the time used to complete the circuit training (20.2 ± 1.6) was half of that needed to complete the traditional interval training (40.3 ± 1.8). Significant increases (p < 0.05) in thiobarbituric acid reactive substances (40%), creatine kinase (CK) (67%), glutathione (14%), and uric acid (25%) were detected posttraditional interval training session in relation to pre. In relation to circuit training, a significant increase in CK (33%) activity postsession in relation to pre was observed. Statistical analysis did not reveal any other change in the oxidative stress biomarker after circuit training. In conclusion, circuit resistance-hypertrophy training scheme proposed in the current study promoted lower oxidative stress biomarkers and antioxidant modulations compared with resistance traditional interval training.

Efeitos agudos de diferentes métodos de treinamento com pesos sobre o gasto energético em homens treinados

“…Thus, besides greater lactate production, it was expected that the TM induced to greater muscle damage when compared with the CM. Deminice et al 30 after having compared the TM performed with three sets, 10 repetitions, 75% of 1RM and 90 seconds of rest interval and the CM with similar work and without rest interval, observed that the methods are not significantly different compared with muscle damage, although both have presented increase in the creatine kinase enzymatic activity post-exercise. Thus, it seems that when the subjects are trained and the training methods are standardized by work, both CM and TM produce similar responses related to muscle damage.…”

Creatine supplementation reduces oxidative stress biomarkers after acute exercise in rats

“…Several studies have shown increased oxidative stress biomarkers after acute exercise in rats (Bachur et al 2007) and humans (Michailidis et al 2007;Deminice et al 2011). The extent of oxidation is dependent on the exercise mode, intensity, and duration (Bloomer 2008).…”

“…41 Egzersiz sırasında SR üretimi egzersizin tü-rüne, şiddetine ve süresine bağlıdır. [44][45][46] Bunun en önemli sebebi, farklı egzersiz türlerinin farklı enerji gereksinimlerinin olması ve bundan dolayı farklı oksijen tüketim seviyelerine neden olmasıdır. Bunun sonucunda dokularda oluşturdukları farklı mekanik streslerin etkisi ile farklı kaynaklardan SR üretimini tetiklemesidir.…”
