Motor activities and some football skills reported to young players during varied heat of the weather are subject of actual researches. The aim of this study is to find out the changes of specific parameter performances during different levels: low (LT):12-16℃ and hot (HT):32-36℃ of temperatures. Methodology: Two young categories playing in Tunisian football championship (their ages were 15-16 years: n= 11, height, 165.7± 1.65cm, weight, 62.4 ± 2.17 kg, sport stage 7±0.8years, and 17-18 years: n= 10, height, 169±2.82cm, weight, 63.7±2.25kg, stage 9±1.2years) were observed during the matches (n=8) in (LT) and (n=7) in (HT), using GPS monitor along with their movements with and without the ball. All observed selected players participated in full matches (90min). There were significant changes in the performances of the studied variables of 15-16 years old in high speed, which decreased from 383m in (LT) to 285m in (HT), at p n= 7.4 in (HT), p In order of these findings we appreciate that exercises provided by the physical coaches should be in intensive form of charge during (LT) and with moderate intensity during the (HT) level similarly for the two categories. |
