The response of the adrenal cortex to a stressor consisting information about surgery be performed following day was studied in 34 patients by monitoring changes salivary cortisol. From those, 18 were subjected an individually selected 1 h music program, applied immediately receipt information, and remaining 16 formed reference group. Another 10 patients, not awaiting surgery, served as controls. Saliva sampled before 5 more samples collected at 15 min intervals. produced 50% rise cortisol...
Abstract Herbal and nutritional supplements are more popular in the western population. One of them is an extract exotic plant, named Tribulus terrestris (TT). TT a component several that available over-the-counter widely recommended, generally as enhancers human vitality. touted testosterone booster remedy for impaired erectile function; therefore, it targeted at physically active men, including male athletes. Based on scientific literature describing results clinical trials, this review...
Background: Kickboxing is a combat sport where athletes require constant supervision of coach. The outbreak the pandemic caused by SARS-CoV-2 has led to crisis in many sectors, including sport. Global efforts limit spread pathogen resulted temporary lockdowns that limited sporting activity, thus deteriorating athletes’ physical fitness. Methods: participants included 20 kickboxers competing at international level. Their fitness was evaluated based on test developed International Committee...
Intensive physical activity largely modulates resting concentrations of blood cortisol (C) and testosterone (T) their molar ratio, which is defined as the anabolic-catabolic index expressed T/C × 102. The aim study to evaluate effect author's high-intensity training program on T, C, 102, selected fitness indices in men between 35 40 years age. experiment was conducted a group 30 healthy men, divided into control experimental groups. followed 8-week program, included three sessions per week,...

Abstract Background Kickboxing is a popular striking combat sport, and K-1 type of kickboxing. Direct head blows can cause significant long-term injury affect brain wave activity. Objectives We aim to compare the changes in activities fighters during kickboxing contest those control group, who were punching bag not hit by another athlete. Methods A total 100 professional Polish kickboxers split evenly into experimental ( n = 50, age 25.5 ± 4.63 years) 26.6 5.22 groups. used quantitative...
Some equivocality exists regarding the effect of testosterone (T) on competitive performance with cortisol (C) implicated as a moderating factor. This study investigated whether C is T relationship Olympic weightlifting (OWL) during real and simulated competitions. We monitored 105 male athletes (age 19.3±3.7 years); 46 OWL competitions (e.g., national age championships) 59 across events talent identification). Serum were assessed before warming up within 15 minutes event completion....
To examine the steroid hormone effect on physical performance of young athletes during an Olympic weightlifting competition.26 boys and 26 girls were monitored across 2 competitions. Pre- post-competition testosterone (T), cortisol (C) dehydroepiandrosterone-sulfate (DHEA-s) measured in blood, with pre-event free T (FT) androgen index (FAI) calculated. Body mass (BM) recorded.The had a larger BM, superior more T, FT higher FAI than (p < .01). Although C (32%) DHEA-s (8%) levels elevated...
Acid-base balance (ABB) is a major component of homeostasis, which determined by the efficient functioning many organs, including lungs, kidneys, and liver, proper water electrolyte exchange between these components. The efforts made during competitions combat sports athletes such as kickboxers require very good anaerobic capacity, which, research has shown, can be improved administering sodium bicarbonate. Combat are also characterized an open task structure, means that cognitive executive...
Accumulation of musculoskeletal overload experienced daily over a long period, for months or even years may lead to serious health problems. Simple, quick and easy-to-administer prophylactic therapeutic interventions not involving complicated medical procedures can bring tangible benefits sufferers. The aim the study was evaluate efficacy effects massage programme performed during breaks at work among persons exposed long-term spinal column areas around spine.We studied 50 office workers (20...
Concomitant effects of temperature and pH on changes in the magnitude free, unbound fraction cortisol human serum were studied at temperatures ranging from 36 to 39 degrees C 6.9 7.4, respectively. Free increased with increasing decreasing pH, two factors acting synergically: a rise caused an about 30% increase free = 6.9--over 2.2-fold. At highest temperature-acidity combination, i.e. C, 6.9, was as much 2.5-fold higher, relative standard conditions (ph 37 C). This implies that vivo...
Background This study examined the utility of salivary testosterone (T) and cortisol (C) concentration measures for assessing acute stress responses junior athletes during a sporting competition. Methods Paired capillary blood saliva samples were taken from 71 (45 males, 26 females) before after simulated Olympic weightlifting The T C referenced against total ( TT ) TC concentrations. All hormones tested by immunoassay. Results competition promoted an increase in concentrations male...
Concomitant effects of temperature and pH on changes in the magnitude free, unbound fraction testosterone human serum were studied. Free was determined by equilibrium dialysis undiluted against buffer microchambers at temperatures ranging from 36 to 39 degrees C 6.9 7.4. increased with increasing decreasing pH, two factors acting synergically. This is reflected fact that a rise causes only slight increase free = 7.4 (about 7%), while about 35%. At 1.5-fold higher than standard conditions (37...
D-aspartic acid (DAA) is promoted as a testosterone (T) enhancing supplement by mechanisms involving the hypothalamic-pituitary-gonadal (HPG) axis. Here, we investigated short-term effects of DAA on serum biomarkers HPG-axis in male climbers. Using single-blinded, placebo-controlled design, 16 climbers were randomly assigned to either (3 g/day) or placebo for 2 weeks. The reverse treatment commenced after 2-week washout, with all conditions administered balanced manner. subjects maintained...

Background: Kickboxing is a combat sport with high demands on fitness and coordination skills. Scientific research shows that kickboxing fights induce substantial physiological stress. Therefore, it important to determine the body composition of athletes before competitions analyze skin temperature pH during fight. Methods: This study aimed composition, temperature, in kickboxers fight according K1 rules. A total 24 (age range: 19 28 years) competing local league participated present study....
Blood lipid profiles consist of total cholesterol (TC) and its fractions, high-density lipoprotein (HDL), low-density (LDL), non-high-density (non-HDL), triglycerides (TG). For several decades, studies have examined the effects various factors on status association with risk developing arteriosclerosis cardiovascular disease. The beneficial increased physical activity health been demonstrated by appropriate modulation profiles. individuals low activity, literature recommends engaging in...
