Sports genomics and endocrinological testing for exercise
Good hormone balance means good physical workout. By testing your hormone levels we can quantify how efficient your routines are before your exercise efficiency can be measured in your strength or speed. Some people get better results in a short time when doing physical activity while others need more intensity or more time to get the same results. Salivary hormone testing can quantify this efficiency --most times earlier than a weight scale or chronometer. Certain variations in the DNA indicate the physical activity requirements depending on our genotype. There are also genetic variations that tell us what kind of sports activities (endurance or sprint) is more favorable.
This test measures the free (protein unbound) component of total testosterone through a single saliva sample. Testosterone is a male sex hormone, which is used to evaluate the androgynous state of men and to diagnose polycystic ovary syndrome and breast cancer in women. It is responsible for bone and muscle strength, as well as mood, energy, and sexual function. It also has an influence on muscle mass, physical strength and bone density. Persometrics does not offer advice or medical diagnostics. Rather, the outcome of this test could be useful for you to discuss further with your medical doctor.
Note: We aim to ship your testkit within one working day. However, since the bioavailable component of Testosterone is requires a complex method to analyze correctly, saliva samples are forwarded to a larger laboratory for analysis (the Risch laboratory of Bern). For this reason, please allow for an 8 working days delay before achieving your results (after our laboratory receives your samples). We apologize for this long waiting time, but our main priority is product quality and scientific excellence.
Find the right time of day for your training and exercise
This product includes four sampling vials to measure your anabolic/catabolic hormone ratio (Testosterone/Cortisol) across the day (total hormone analyses: eight). The aim is to identify a solution optimal for you to identify your optimal time of day for your workout.Learn more.
Good hormonal balance means good exercise routines. The Circadian anabolic/catabolic ratio test kit includes an analysis of Free (unbound) Cortisol and Testosterone across the day. Testosterone plays a vital role in creating muscle mass, improving bone density and increasing cardiovascular health. Cortisol, on the other hand, is known to have a catabolic effect on tissue with an associated decrease in anabolic (muscle growth) hormones and suppressed immune function. The optimal hormonal environment for maximal muscle growth (or minimal muscle loss) is when testosterone is high and cortisol is low. Both these two hormones follow a diurnal, or circadian, cycle whereby they sharply increase in the morning to their maximum peak, and then decrease throughout the day, reaching their minimum again at night. If you choose to use the test to assess your diurnal secretion, remember that cortisol increases in function of stress; and testosterone may also increase in some males during or after a competition, so try to choose typical days (one that is common in your current life situation) for your testing.
Are you looking to improve the efficiency of your workout? Do you feel your progress is halted? Learn what sports genomics can you do for you.
Sports genomics is a relatively new scientific discipline that has focused on the study of genetic markers associated with athletic genetic performance. Information derived from DNA profiling can indicate both advantages and genetic barriers that reflect on the athletic performance phenotype.
Personalized and individualized performance improvement strategies to enhance and exploit the genetic advantages or overcome genetic barriers can be implemented to optimize the physical fitness, sports performance and health of an athlete. The DNA test kit from Persometrics provides requires a saliva sample to be returned to our lab. From this, we provide you a report to tell you about your muscle fiber type, your VO2-max, your risk of injury, and finally your energy and metabolic efficiency.
The genes analyzed are ACE; ACTN3; BDKRB2; COL1A1; and PPARA.
DHEA (Dehydroepiandrosterone) is sometimes dubbed the anti-aging hormone. It is an anabolic compound that can buffer the negative effects of cortisol on several bodily functions and illnesses and can protect against burnout, Alzheimer's, and migraine. DHEA-s (Dehydroepiandrosterone sulfate) is the sulfated form of DHEA, which represents close to ninety-eight percent of the total circulating DHEA in our body. DHEA-s also shows less of an inter-individual variance (both from one day to another, or different times of the day), and is not easily affected by stressors, making testing of DHEA-s more suitable than DHEA as a health biomarker. Correspondingly, the ratio of DHEA-s over Cortisol often has a stronger effect size on illness than either of the two hormones alone. To obtain saliva for this test, you provide one sample only. Your results will present a reference range as well as an overview of the importance of Cortisol/DHEA-s for health markers.
The testosterone to cortisol (T/C) ratio is used to assess physiological strain and recovery after exercise. As testosterone is an anabolic hormone and cortisol a catabolic hormone, this ratio is often referred to as the anabolic ratio, and measurement is pivotal for endocrine homeostasis during acute and chronic exercise. Indeed, it has been proposed to be linked to overtraining. Recent research also shows that this ratio is of importance to female athletes.
This test involves performing four saliva samples surrounding a work-out session (immediately before, immediately after, 1 hour after and finally 12 hours after a session). From your four samples, we extract both cortisol and testosterone, yielding a total of eight analyses. Benchmarking your levels before exercise, this test is above all to be used for intra-individual analysis. The reference range for overall testosterone and cortisol are provided, and your T/C parameter will be placed in relation to published literature using this ratio.
