Uticaj treninga snage na nivo testosterona kod muškaraca
The effect of strength training on the testosterone level in men
Sažetak
Primarni cilj ovog rada je da pruži uvid u efekte treninga snage na nivo testosterona (TE) kod muškaraca, kao i mehanizme anaboličkog dejstva testosterona na mišićni aparat čoveka. Poznato je da je jedan od načina povećanja mišićne snage ide preko povećanja mišićne mase (periferni faktor), a u osnovi tog procesa je delovanje TE. Prikupljeni podaci potvrđuju zaključke određenog broja dosadašnjih istraživanja, od kojih je veći broj novijeg datuma, a oni se odnose na uticaj različitih metoda treninga snage (H - submaksimalnih naprezanja do otkaza, S - maksimalnih naprezanja, P - dinamičkih naprezanja) sa jednako primenjenim ukupnim obimom opterećenja, kao i uticaj različitog trajanja pauza u treningu snage na nivo TE kod muškaraca. Prikazanim rezultatima istraživanja potvrđene su tvrdnje da je H metoda najdelotvornija i opravdano nazvana ,,metodom za hipertrofiju mišića'. Kada je u pitanju trajanje pauza, optimalnim su se pokazale one koje traju oko 90 sekundi, jer je ovaj period imao najviše uticaja na nivo mlečne kiseline i kateholamina u krvi, koji se smatraju da su ključnim faktorima uticaja na povećano lučenje TE (ovaj hormon je determinisan i u grupu stres hormona). Dalja istraživanja su neophodna na ovom polju po mišljenju mnogih autora, kako bi se sa većom sigurnošću utvrdila uzročno posledična veza.
Abstract
Primary objective of this study was to provide the insight into the effects of strength training on the testosterone (TE) level in men, as well as the mechanisms of anabolic effects of testosterone on human muscle apparatus, since it is known that one of the ways to increase muscle strength is through the increase of muscle mass (peripheral factor), and the basis of this process is the effect of TE. The collected data summarize the conclusions of a number of previous studies, out of which larger number of recently, and they relate to the effect of different methods of strength training (H - submaximal effort to failure, S - maximal effort, P - dynamic effort) with equally applied total volume of load, and the effect of different rest periods in strength training on the level of TE in men. The presented results confirmed the claims that the H method is the most effective and reasonably called 'the method for muscle hypertrophy'. When it comes to rest periods, the ones that last for about 90 seconds proved optimal because this period had most influence on the level of lactic acid and catecholamines in blood which are considered to be the key factors for the increased secretion of TE (this hormone was included in a group of stress hormones as well). However, according to many authors, further examinations in this field are necessary in order to determine the causal link with greater certainty.
