“…In another study, it was suggested that the activities of catalase and superoxide dismutase increased while the level of malonaldehyde (MDA) decreased after 3 months of specific training in elite karate practitioners. This study showed contradictory results because increased activities of antioxidant enzymes were observed in the presence of elevated level of a marker of oxidative stress (25). This contradictory result could have been due to a large variation in the average of each parameter.…”

Interest and participation in competitive Martial Arts such as Taekwondo, Karate, Kung Fu, Aikido, and Tai Chi is growing in children, adolescent as well as in adults in the USA and worldwide. Competitive Martial Arts require daily training weeks and sometimes, months prior to the start of a competition or tournament. The training period could be for a few hours daily over a period of one to six months with one or two days for every one week for rest and recovery. The types and extents of injuries after competition depend upon the form of Martial Arts and the type of physical contact. They include muscle, joint, head and neck, groin, upper and lower extremities, and soft tissues. Some acute injuries can be taken care of at home and the injured may recover quickly. Some injuries may require hospitalization and even surgery; while others may take longer period to recover and require stoppage in training. The training involves daily exercises during which moderate levels of reactive oxygen species (ROS) are produced. ROS activates a transcriptional factor Nrf2 (nuclear factor-erythroid 2-related factor 2) which enhances the levels of antioxidant enzymes; and thereby, reduces oxidative stress. Because of this observation, some investigators have suggested that supplementation with micronutrient and antioxidant compounds is not necessary for reducing injuries and improving the rate of healing from injury. Appropriate diet recommended for Martial Arts athletes are sufficient to reduce oxidative damage and protect against injuries that occur during Martial Arts competitions. The use of a single antioxidant in reducing oxidative stress has produced inconsistent results in reducing the markers of oxidative stress. The limitations of such an approach are briefly discussed. This review has proposed a mixture of micronutrients which may reduce oxidative stress and improve performance in Martial Arts competitions. In addition, some beneficial effects of Martial Arts are also described.

“…Tolerance increase to exercise-induced oxidative stress was demonstrated, among others, after aerobic training in overweight/obese adolescent girls [ 86 ]. An adaptive increase in antioxidant enzyme activity after training was indicated after 3 months of karate training in elite athletes [ 87 ] and in the erythrocytes of handball athletes during 6 months of monitoring [ 88 ]. Some of the research also proves that a single bout of exercise confers increased resistance to a subsequent non-exercise oxidative challenge, but only in young people [ 89 ].…”

Cardiovascular diseases constitute the most important public health problem in the world. They are characterized by inflammation and oxidative stress in the heart and blood. Physical activity is recognized as one of the best ways to prevent these diseases, and it has already been applied in treatment. Physical exercise, both aerobic and anaerobic and single and multiple, is linked to the oxidant–antioxidant imbalance; however, this leads to positive adaptive changes in, among others, the increase in antioxidant capacity. The goal of the paper was to discuss the issue of redox equilibrium in the human organism in the course of cardiovascular diseases to systemize updated knowledge in the context of exercise impacts on the organism. Antioxidant supplementation is also an important issue since antioxidant supplements still have great potential regarding their use as drugs in these diseases.

“…Another study published in 1999 demonstrated that there was no difference between the effect of physical activity under moderate intensity on oxidative stress for pre-menopausal and post-menopausal women [ 18 ]. In 2017, Jemili’s team identified that a 3-month specific training program could improve the redox balance of elite karate athletes and should be recommended for athletes with similar physical fitness levels [ 19 ].…”

Intracellular Oxidative Stress Induced by Physical Exercise in Adults: Systematic Review and Meta-Analysis

A physical exercise program is one of the commonly used methods for improving an individual’s antioxidative capacity. However, an inappropriate physical exercise program would induce extra oxidative stress (OS), and the relationship between the details of a physical exercise protocol and the severity of intracellular OS is still unclear. A systematic review and meta-analysis of randomized controlled trials were conducted by searching PubMed, Medline, and Web of Science with the eligibility criteria: (1) participants over 18 years old; (2) physical exercise interventions; (3) 8-hydroxydeoxyguanosine, F2-isoprostanes, and protein carbonyls (PCs) as outcome measures; (4) published in English and peer-reviewed. 12 studies were included, and the data of 8 in them were pooled together. The agreement between authors reached a kappa value of 0.73. The results of the meta-analysis showed that: (1) the level of OS did not depend on the absolute intensity of physical exercise but on both the intensity and the volume of exercise; (2) high-intensity aerobic exercise (HIAE) and a combined protocol of HIAE and resistance training had the highest potential to induce large OS in unhealthy people; (3) the OS induced by moderate-to-high intensity aerobic exercise was significantly larger than that induced by ordinary life activities in healthy adults; (4) high-intensity interval training and moderate-intensity aerobic exercise had the lowest and sub-lowest probabilities to induce high intracellular OS for unhealthy adults. activities induce OS in various tissues in the human body, and the severity of OS depends on many factors of physical exercises as well as the health condition of an individual. A high-intensity and high-volume physical exercise program has the largest possibility of inducing severe OS, while a moderate-intensity aerobic exercise program and a high-intensity interval training program with a relatively low volume might be beneficial to the redox balance for unhealthy individuals. In conclusion, continuous aerobic exercise under moderate-intensity or high-intensity interval training could be recommended to enhance the body’s capacity for maintaining redox balance, especially for unhealthy individuals.
