“…Similarly, Park and Kwak demonstrated that a graded exercise test on a treadmill did not affect plasma MDA levels in aerobically and anaerobically trained athletes [27]. In contrast, our results are inconsistent with studies that reveal an increased level of serum MDA after submaximal circuit resistance exercise [28] and after an acute bout of upper-and lower-body resistance exercises at low intensity (3 sets of 20-30 repetitions at 25-30% of 1RM) [11] in non-resistance-trained subjects. Moreover, high-intensity circuit resistance exercise leads reportedly to a more considerable increase in serum MDA levels in comparison with the low-intensity circuit resistance exercise in sedentary males [23].…”

“…In addition, one bout of Olympic weightlifting at an intensity corresponding with 85-90% one-repetition maximum (1RM) has been reported to increase serum MDA levels significantly and to remain elevated 48 h after the morning training session in elite weightlifters [10]. Moreover, plasma MDA levels have reportedly increased after three sets of upper-and lower-body resistance exercise at low intensity (25-30% 1RM) in untrained male students [11]. In contrast, both chronic hypertrophy-and strength-intensity whole-body resistance decrease MDA concentration in previously untrained men [12].…”

The aim of the current study is to compare the effects of hypertrophy-, strength-, and power-type resistance exercise training types on hydrogen peroxide (H 2 O 2), malondialdehyde (MDA), total lactate dehydrogenase (LDH), and total creatine kinase (CK) in resistance-trained women. Methods After determining one-repetition maximum (1-RM), ten resistance-trained women (age 26.30 ± 4.95 years; body mass index 22.07 ± 2.02 kg/m 2 ; body fat 24.64 ± 4.98%) conducted hypertrophy-type (70% of 1-RM), strength-type (90% of 1-RM), and power-type (45% of 1-RM) resistance exercise for three consecutive weeks. The movements included lever leg extension, reverse-grip lat pull-down, horizontal leg press, standing biceps cable curl, lying leg curl, machine bench press, standing cable triceps extension, and seated calf raises. Fasting blood samples were obtained immediately before and immediately after each trial. Statistical analyses were performed using the t test, Wilcoxon, and analysis of covariance. The significance level was set at P < 0.05 level. Results The results indicated that one bout of hypertrophy-, strength-, and power-type resistance exercises had no significant effects on H 2 O 2 , MDA, and total LDH levels. However, serum total CK level significantly increased after all the three types of resistance exercise. Power resistance exercise resulted in a higher total CK level than hypertrophy and strength types. Conclusion Although the three types of hypertrophy, strength, and power exercise cause muscle damage, they do not exacerbate oxidative stress in resistance-trained women.

Edited by: Shigehiko Ogoh New Findings r What is the central question of this study?What is the influence of a single bout of exercise on the properties of erythrocyte fractions at different ages? r What is the main finding and its importance?A single bout of exercise in untrained men induced oxidative stress in erythrocytes and had an influence on antioxidant defense in these cells. Old erythrocytes were more sensitive to oxidative damage than young and middle-aged cells. Higher levels of glutathione in old erythrocyte fractions did not protect them against oxidative stress. It seems that exercise may promote the removal of old erythrocytes from the circulation.The objective of this study was to establish the role of exercise-induced oxidative stress in the erythrocyte fractions [young (YF), middle-aged (MAF) and old (OF)] of young untrained men after acute exercise. Blood samples were collected before exercise, immediately after and 1 h after exercise. The maximal power generated was 292 ± 27 W, and exercise duration was 8.73 ± 0.9 min. Different optical properties and oxidative stress parameters were found in each erythrocyte fraction. Total thiols in YF and MAF after exercise and after 1 h rest were similar to values before exercise; however, in OF {32.7 ± 9.8 nmol [mg haemoglobin (

“…They did not observe a significant change in H 2 O 2 and MDA levels due to the resistance training [ 82 ]. In contrast, they reported that plasma MDA levels had increased after three sets of resistance exercises in untrained men [ 83 ]. Based on the evidence, variations of training intensity and volume, or both (high volume-low intensity or low volume-high intensity training) likely have a positive influence on the elevation of GSH concentration [ 84 ].…”

Creatine Supplementation, Physical Exercise and Oxidative Stress Markers: A Review of the Mechanisms and Effectiveness

Oxidative stress is the result of an imbalance between the generation of reactive oxygen species (ROS) and their elimination by antioxidant mechanisms. ROS degrade biogenic substances such as deoxyribonucleic acid, lipids, and proteins, which in turn may lead to oxidative tissue damage. One of the physiological conditions currently associated with enhanced oxidative stress is exercise. Although a period of intense training may cause oxidative damage to muscle fibers, regular exercise helps increase the cells’ ability to reduce the ROS over-accumulation. Regular moderate-intensity exercise has been shown to increase antioxidant defense. Endogenous antioxidants cannot completely prevent oxidative damage under the physiological and pathological conditions (intense exercise and exercise at altitude). These conditions may disturb the endogenous antioxidant balance and increase oxidative stress. In this case, the use of antioxidant supplements such as creatine can have positive effects on the antioxidant system. Creatine is made up of two essential amino acids, arginine and methionine, and one non-essential amino acid, glycine. The exact action mechanism of creatine as an antioxidant is not known. However, it has been shown to increase the activity of antioxidant enzymes and the capability to eliminate ROS and reactive nitrogen species (RNS). It seems that the antioxidant effects of creatine may be due to various mechanisms such as its indirect (i.e., increased or normalized cell energy status) and direct (i.e., maintaining mitochondrial integrity) mechanisms. Creatine supplement consumption may have a synergistic effect with training, but the intensity and duration of training can play an important role in the antioxidant activity. In this study, the researchers attempted to review the literature on the effects of creatine supplementation and physical exercise on oxidative stress.
