Soccer preparation requires the use of aerobic and anaerobic energy systems, which can be achieved by the intensity distribution of training. This study aimed to evaluate the effect of 4 weeks of polarizing training on aerobic and anaerobic fitness variables in soccer players. 20 soccer players in Tehran soccer league were divided
into polarized (n=10; 52.11 ml/kg/min) and usual soccer training (n=10; 53.31 ml/kg/min) groups based on maximum oxygen consumption. Subjects were evaluated before and after four weeks of polarize (four-session consisting of three sessions of high volume -low-intensity training followed by a high-intensity interval training session) and usual soccer training (Four sessions per week including two sessions of high-intensity interval training, one session of lactate threshold training and one session of low-intensity training) to measure maximal oxygen consumption and soccer-specific, mean and peak power and respiratory exchange ratio. Maximum oxygen consumption, peak power, soccer-specific Maximum oxygen consumption and respiratory exchange ratio were significantly increased after four weeks of polarized and usual soccer training (P<0.05). Also, the polarized training model resulted in a significant increase in maximal oxygen consumption, peak power, and specific soccer maximal oxygen consumption compared to the usual soccer training model (P≤0.01). The results showed that the distribution of training intensity based on the polarized model can be more effective in short term than the usual soccer training in off-season preparations.
