DIFFERENT GAME RULES LIKE FREE PLAY AND CONTROL PASS INFLUENCING PHYSIOLOGICAL RESPONSES TO SMALL-SIDED GAMES IN YOUTH PLAYERS

The purpose of this study was to determine the difference between the frequently applied physiological answer to small sided games like free play and controlled pass games by changing the field size number of players and rules of the games during football practices. The participants of this study composed of 16 volunteer sportsmen belonging to a professional 2nd League of ages 14.9 ±0.25, having a height of 170.2 ±7.13 cm and weight 58.56 ±5.35 kg with a heart beat rate of max.198.5 ±4.58 beats/min. The participants first underwent anthropometric measurements and then Yo-Yo1 intermittent recovery test. Afterwards 4x4 free play and 4x4 controlled pass games comprising of 4 sets each were played each 2 days apart. At the end of the small field games, the result of the 4x4 games of 4 sets in terms of heart beat rate (HBR) % age of maximum heart beat rate (%HBR max.) and the number of meeting with the ball was 183.1 ±1.85 beats/min, 92.36 ±0.94 %,10.73 ±0.91 for free play and 179.5 ±3.05, 90.67 %,10.04 ±0.91 for controlled pass games. The mean HBR or %HBR max. values for each dependant group were calculated by using t-tests and the number of meetings with the ball was evaluated using the Wilcoxon equivalent 2 example test (p 0.05). The HBR and % HBR max values of players for 1,3 and 4th set were found to be insignificant (statistically not different) (p 0.05). The HBR and % HBRmax values of the 2nd set were found to be statistically significant (p 0.05). The difference in the 2nd set might be related to the loss of concentration of the players. To conclude ,based on the physiological response to 4x4 sports free play and control pass games are similar in terms of intensity and these types of practices can also be used during endurance training.
