Maximum aerobic power, lower limb explosive strength and isokinetic peak torque in chilenean professional and college soccer players

Abstract

Soccer is a sport that requires according to their physiological characteristics, aerobic-anaerobic performance, as well as muscle strength and power. To determine functional characteristics in Chilean professional soccer players and compare them with college soccer players, 40 professional soccer players and 19 college soccer players were evaluated. It was determined his Vo2 max, Squat Jump (SJ), Counter Movement Jump (CMJ), Abalakov (ABAL) and peak torque to the knee extension of isokinetic at speeds of 60 ° / s, 180 ° / s and 300 ° / S. The results showed a Vo2 max of 56.2 ± 5.7 mlO2/min/kg, for professionals and 50.4 ± 4.06 mlO2/min/kg for college players (p <0.05). For SJ value was 36.2 ± 2.7 cm, 30.6 ± 3.2 cm; for CMJ was 41.4 ± 4.1 cm, 35.8 ± 3.5 cm; for ABAL was 48 , 5 ± 4.6 ± 3.7 cm and 41.6 cm for professionals and college players respectively (p <0.05). The average peak torque of the lower extremities was to 60 ° / s 220.6 ± 29.7 Nm and 195 ± 30.5 Nm; to 180 ° / s was 148 ± 18.7 Nm and 135.7 ± 19.1 Nm; to 300 ° / s was 113.3 ± 15.9 Nm and 101.8 ± 16.3 Nm for professionals and college players respectively. There was a significant difference in 60 ° / s and 300 ° / s (p <0.05). Vo2 max values are for professionals in the lower range reported by other research. It also happens to the peak torque isokinetic to 60 ° / s and 180 ° / s. With regard to the values of SJ and CMJ, according to reports data C. Bosco, the players are at a level similar to other professional players. In conclusion, for the variables studied, professional players show highest values compared to college players. However, in the international context, the values of the professionals are lower.
