Hormones, secreted by endocrine glands in the body, are substances that regulate the function of body cells, tissues, organs or systems.

fitnessExercise places a major challenge on the body owing to the increased energy it requires and the physiological demands it puts on the body’s nervous, muscular, cardiovascular, metabolic and respiratory systems.

During physical exercise, free salivary cortisol, DHEA and testosterone concentrations increase with the intensity of the exercise.

It is particularly important in fitness exercise and sports medicine to note that hormone levels and exercise-induced hormone changes vary among subjects with different types of training.

Whereas endurance-trained subjects display a less pronounced hormone response to exercise, there are some differences between endurance and resistance sessions:

  • Resistance-trained subjects demonstrate a more pronounced hormone response to exercise
  • Increased cortisol may indicate an intensity- rather than a mode-dependent response

Monitoring hormone levels during fitness sessions is found to be a useful tool for optimizing athletes’ training status and identifying any excessive exercise resulting in overtraining syndrome.

Salivary cortisol, DHEA and testosterone determinations are useful in fitness and sports medicine research. The use of these biological markers is based on the assumption that these salivary steroids may reasonably be taken to reflect the hypothalamic pituitary-adrenal (HPA) axis function. Indeed, in the diagnostic setting, salivary cortisol levels parallel those in plasma following. ACTH and CRH stimulation, and following exercise-induced stress.

Why are Hormones significant for Fitness Optimization?

  • Intensity of exercise increases the concentrations of specific biological stress markers such as DHEA, Cortisol, and Testosterone.
  • Excessive exercising may result in “overtraining syndrome” potentially leading to adverse physiological and psychological symptoms.
  • These symptoms have detrimental affects on an individual’s athletic performance and ability to recover.


Saliva is the ideal choice of specimen to measure cortisol and other hormone levels. Saliva measures the “Unbound Biologically Active,” or free hormone levels in the body. When blood is filtered through the salivary glands the bound hormone components are too large to pass through cell membranes of the salivary glands. Only the unbound hormones pass through in the saliva.
What is measured in saliva is considered the “free” (bioavailable) hormone, and is indicative of hormone levels that will be delivered to the receptors in the tissues of the body.


Benefits of Saliva Testing for Optimal Health Achievement!

  • Saliva sampling is very easy, non-invasive and easy to collect during fitness exercise. For these reasons saliva measurement is the right choice for evaluating physical conditions during exercise.
  • Eliminate the risk of overtraining syndrome.
  • Measuring of free testosterone in blood is inaccurate and challenging. And can not determine the overtraining syndrome during fitness exercise.
  • Provides accurate, fast and reliable results.
  • Interpretations of lab results provided with clear and detailed information.
  • No costly medical fees: no doctor visit or blood work required.
  • Collect the saliva sample and mail it to the laboratory.
  • Saliva is the specimen of choice in a variety of traditional medical care situations as well as emerging areas of health measuring and monitoring.
