Threshold of anaerobic changes versus final result on a rowing ergometer in 2000 m maximal test – as exemplified by the national Polish rowers team in years 1997–2005

Abstract

Ciklinėse ištvermės sporto šakose, prie kurių priskiriamas ir irklavimas, anaerobinio slenksčio (AT 4) indeksas gali būti laikomas patikimu pasirengimo irklavimo sezonui lygio indikatoriumi (Beneke, 2000; Foster, 1995; Messonnier, 1997). Sisteminė indekso kontrolė padeda pastebėti pirmuosius nukrypimo nuo užsibrėžtų pasirengimo tikslų požymius, tai leistų daryti treniruotės plano pakeitimus (Fitts ir kt., 1996; Kraemer ir kt., 2004; Sharkey ir kt., 2006). Darbo tikslas – aptarti anaerobinio slenksčio lygį, kuris buvo nustatomas 1997–2005 metais irkluotojams (n = 16), besirengiantiems pasaulio čempionatui ir olimpinėms žaidynėms. Autoriai gautus duomenis taip pat palygino su 2000 m irklavimo ergometru „Concept II“ simuliacinio testo rezultatais. Straipsnyje pateikti rezultatai rodo, kad tarp AT 4, pasiekto didėjančiomis fizinėmis pastangomis ir 2000 m specialiojo simuliacinio testo metu, yra stiprus tarpusavio ryšys

In cyclical endurance sports disciplines, and rowing is numbered among them, the index of anaerobic threshold (AT 4) may be considered to be a reliable indicator of the level of preparations for a rowing season (Beneke 2000; Foster 1995; Messonnier 1997). Systematic control of the index helps to notice first signs of a deviation from the defined goal of preparations thus enabling to make adjustments to a training plan (Fitts et al., 1996; Kraemer et al., 2004; Sharkey et al., 2006). The purpose of the work is to present the level of anaerobic threshold observed during rowers’ (n=16) preparations for World Championship and the Olympic Games in years 1997-2005. The authors have also compared the above thresholds with the results obtained during the simulation test of 2000 meters on a rowing ergometer “Concept II”. Results presented in the article show that there is a strong correlation between AT 4 power achieved during progressive physical effort and the results of the simulation specialist test of 2000 meters
