Athletic training is multidimensional, specific, complex and versatile process (Smith, 2003; Issurin, 2008; Gamble, 2010) long-term and developing athlete’s physical capacities and improving mental qualities, comprehensively developing personality, determining its actions, behaviour, self-sufficiency and responsibility, as well as motivating to achieve impressive results. A team is a complex integrated dynamic system (Glazier, 2010; Dutt-Mazumder et al., 2011), which management is very complex due to many determinant factors. In most cases, only the issues of the one side of the athlete training are being discussed. Thus, the possibility to determine the interaction between the athlete’s training and athlete’s sport performance is reduced. It is being constantly researched for new ways to find the most significant, influential training indicators, which would allow controlling athletes’ fitness to be able to achieve the best results in the most important competitions (Busso, 2003; Mujika et al., 2004; Reilly, 2001; Gamble, 2006; Hughes, Franks, 2006). The complexity of athlete training is lately influenced by the increasing number of competitions (Smith, 2003; Issurin, 2008, 2010, 2010a; Borresen, Michael, 2009; Gamble, 2010). This complicates the targeting athlete training for the most important competitions of the year. The athletes’, as well as handball players’ sport performance is influenced by the set training program (Banister et al., 1999; Kotzamanidis et al., 1999...

Komanda yra sudėtinga kompleksinė dinaminė sistema, kurią valdyti yra labai sudėtinga dėl daugybės veiksnių (Glazier, 2010; Dutt-Mazumder et al., 2011). Dažniausiai nagrinėjama tik vienpusiški sportininkų rengimo klausimai, ir tuomet sumažėja galimybė nustatyti tiesioginius ryšius tarp sportininkų rengimo ir parengtumo. Nuolat yra tyrinėjama, ieškoma būdų, kaip rasti svarbiausius, turinčius daugiausiai įtakos rengimo rodiklius, kurie leistų valdyti sportininkų parengtumą, kad svarbiausiose varžybose būtų pasiekta geriausių rezultatų (Busso, 2003; Mujika et al., 2004; Reilly, 2001; Gamble, 2006; Hughes, Franks, 2006). Sportininkų rengimas yra sudėtingas dėl pastaruoju metu gausėjančio varžybų skaičiaus – tai komplikuoja kryptingą sportininkų rengimą svarbiausioms metų varžyboms (Smith, 2003; Issurin, 2008, 2010, 2010a; Borresen, Michael, 2009; Gamble, 2010). Sportininkų (taip pat ir rankininkų) parengtumas priklauso nuo taikomos rengimo programos (Banister et al., 1999; Kotzamanidis et al., 1999; Mester, Perl, 2000; Busso, 2003; Dick, 2006; Gamble, 2006; Ronglan et al., 2006; Drust et al., 2007; Vargas et al., 2008; Carling et al., 2009).

Cardiac muscle is unique because it has the capability of maintaining its own rhythm. If left to this inherent rhythmicity, the heart would beat steadily between 70 and 80 beats per minute. Extrinsic regulation provides for heart rates that may be as slow as 30 beats per minute at rest in highly trained endurance athletes and as fast as 220 beats per minute in maximum exercise. In our research we analyzed different strength training methodics, dynamic and isometric exercise’s influence to the heart rate in fast adaptation. Research showed, that while working at 80% of maximum, isometric physical activity provides higher heart rate than dynamic physical activity at the same intensity.
