Orienteering is an endurance sport that combines physical and cognitive activity, during which the athlete must complete a course with several points distributed over unknown terrain in the shortest possible time. A number of studies have investigated the body's physiological adaptations to the stress caused during competition, but not the immunological changes. To that end, the present study evaluated the immunological, physiological and pathological responses in athletes performing high-intensity physical exercise during an orienteering race. The 30 athletes tested belonged to the elite orienteering category and participated in the regional championship. Cortisol levels were determined before and after the competition to assess stress response, as were the cytokines IL-2, IL-4, IL-6, IL-10, TNF-α, IFN-γ and IL-17 to evaluate the immune response. Cortisol levels increased after the competition, indicating a stress condition. IFN-γ, IL-6 and IL-10 levels also rose post competition. The results indicate that orienteers are exposed to high stress levels, and that this condition affects their immune and endocrine systems, triggering a predominantly anti-inflammatory response, likely an athlete's mechanism of adaptation to the stress imposed by high-intensity physical exercise.

The present study verified the effect of moderate to high intensity aerobic exercise on the endocrine response profile and adipose tissue in young healthy men with different phenotype characteristics.
A single bout of cardiovascular exercise can enhance plasticity in human cortex; however, the intensity required for optimal enhancement is debated. We investigated the effect of exercise intensity on...
This study examined whether the exercise-induced changes in inflammatory cytokines differ between impact and no-impact high intensity interval exercise, and whether they are associated with post-exerc...
High-intensity exercise interventions are often promoted as a time-efficient public health intervention to combat chronic disease. However, increased physical effort and subsequent fatigue can be barr...
No short-term exercise data exist testing whether training intensity modifies hormonal and perceived appetite in obese adults with prediabetes. Therefore, we compared the effects of short-term moderat...
Large interindividual variability exists in the glycemic response to exercise program, resulting in a subset of individuals known as exercise non-responders (NRs). Increasing the intensity...
It has been established that greater amounts of vigorous intensity physical activity lead to improved health outcomes. Interestingly, the response of biologically active substances, called...
The objective of this randomized controlled trial (RCT) is to compare the changes of the sleep-related memory functions in patients with psychosis after they have completed the 12-week hig...
Previous research is equivocal concerning if high intensity interval training is viewed as more aversive versus moderate exercise. Our data in active men and women showed that interval tra...
Despite exercise training decrease blood pressure in 'average' terms, there is a wide interindividual variability after exercise training, being yet unknown what mode of exercise (e.g. end...
A cardiovascular exercise strategy with alternating short periods of intense anaerobic exercise with less-intense recovery periods.
Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.
The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an EXERCISE TEST.
The body's defense mechanism against foreign organisms or substances and deviant native cells. It includes the humoral immune response and the cell-mediated response and consists of a complex of interrelated cellular, molecular, and genetic components.
The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc.

Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
