Efeito das cargas de treinamento sobre parâmetros fisiológicos de futebolistas

Abstract

Abstract:The aim of this study was to investigate the effects of three weeks of training with intensity monitored on the aerobic capacity of professional soccer players. Fourteen players, members of a first division Brazilian Championship team in 2010, aged 22.78 ± 3.06 years were evaluated pre and post three weeks of training. The anaerobic threshold intensity LAn was determined by bi-segmented method, for this four submaximal efforts of 800 meters with intensities 10, 12, 14 and 16 km/h were applied. Thirty three training sessions were quantified in zones according to heart rate related to the LAn (FC LAn ): Z1 -10% below, Z2 -90-100% and Z3 -above the FC LAn . During training participants remained 31.17 ± 14.86%, 42.96% and 25.87 ± 14.90 ± 16.67% in Z1, Z2, and Z3 respectively. There were no significant differences in the LAn (pre = 13,29 ± 0,71 km•h ), perceived exertion (pre = 11,53 ± 1,45 u.a; post = 11,23 ± 1,53 u.a) and FC LAn (pre = 166,64 ± 10,69 bpm; post = 174,50 ± 10,89 bpm) between conditions before and after training, indicating that three weeks of training are insufficient to generate positive changes in soccer players LAn.

Analysis and comparison of intensity in specific soccer training sessions

“…Several recent studies have been shown that both the technical and tactical and physical capacities could be trained simultaneously during varied soccer training drills, such as small-sided games (Köklü, 2012;Köklü, Albayrak, Keysan, Alemdaroğlu, & Dellal, 2013;Owen et al, 2012), circuit ball training (Hoff, Wisloff, Engen, Kemi, & Helgerud, 2002) and even friendly matches (Fernandes, 2002). However, just few studies evaluated the exercise intensity of specific tactical and technical training, what would be important since they are commonly used by coaches (Campos et al, 2013).…”

“…HR is a valid measure of the intensity during aerobic activities due to its linear relationship with VO 2 even during intermittent activities like soccer (Bangsbo, 1994). In addition, monitoring HR is considered the easiest and most recommended tool to assess official soccer match intensities (Campos et al, 2013;Dellal et al, 2012). Furthermore, since the soccer game requires sprint performance, and it has been demonstrated a significant correlation between the anaerobic threshold and repeated sprint ability (Silva, Guglielmo, Dittrich, Floriano, & Arins, 2011), measurement of exercise intensity based on the Lactate Threshold (LT) should be implemented (Eniseler, 2005;Campos et al 2013).…”
