Laser photoacoustic spectroscopy (LPAS) is growing quickly in its applications to real world problems—one of the problems is to prevent obesity—being a candidate technology for breath analysis applications. The ongoing paper is aiming to investigate the evaluation of oxidative stress in womens practicing Kangoo Jumps (KJ) aerobics. Because it is not possible to directly measure free radicals in the body, we approach that by measuring the by-products (breath ethylene) that result from free radical reactions. We found out that the mixture of exhaled breath in women's after the KJ exercises contains low concentration of ethylene compared to the exhaled breath of the women before the start of exercise program. This result can add valuable information to the contribution to reduce the generation of prooxidants during and after KJ aerobics. 1. Introduction There is no doubt that regular sporting activity has physiological benefits, but there is no evidence that there are benefits of extreme endurance sports. Indeed, there are indications that ultra-distance runners, for example, may suffer increased health risks due to high oxidative stress, which generates aggressive oxygen radicals and metabolites that can damage cells and cell components [1–3]. Several interesting concepts have emerged from these types of experimental studies [3–10]. Regular physical exercise enhances the antioxidant defense system and protects against exercise-induced free radical damage. This is an important finding, because it shows how smart the body is about adapting to the demands of exercise. These changes occur slowly over time and appear to parallel other adaptations to exercise. When exercising, the body is in an elevated aerobic metabolic state that increases the production of free radicals. That happens because the two primary fuel sources in the body, carbohydrates and fats, convert into energy through a process called oxidation. During oxidation, not all oxygen atoms bind with hydrogen, thus ending up as free radicals. Normally, the body wants to stay in an oxidative balance, with equal numbers of free radicals and antioxidants, which are free-radical inhibitors [10–12]. Running is one of the earliest and simplest types of aerobic activity. The combination of science and technology has led to the evolution of new forms of running. KJ boots are an example of a new innovative technology that is continuing the evolution of this age-old activity and is defined to be the newest way to getting rid of stress. These boots are designed to dissipate the impact stress and forces
