ABSTRACT:
Introduction
Soccer is art and effort. It’s characterized by the effort intermittence, where the low and the moderate intensity are frequently interrupted by the high intensity efforts. But it is, above all, a sport where the ability to control the ball is based on the excellent physical capacities. The skill evaluation is subjective and difficult to analyze, but the physical effort can be evaluated .
Description of the activities
During a competitive match a player covers approximately 10 Km, from which 8 to 18% are top speed [1]. An international mid-fielder covers 10.8 Km, with a range of 9 to 14 Km, and 0.7% are high speed (21 Km/h) and 0.4% are top speed (30 Km/h) [6]. 50% of the actions of player last 1 to 3 sec, but in the pressing soccer 12% of the actions take 10 sec to cover distances of 40-50 m [4].
Methods and Material
82 young healthy soccer players a) Junior C (n=33) -- 12-14 years of age b) Junior B (n=23) -- 15-16 years of age c) Junior A (n=26) -- 17-19 years of age.
4 to 6 weekly workouts (90-120 minutes)
1 official game / week
Players of F. C. Porto
Methods and Material
3 pairs of photo-electric cells, connected to 2 digital watches, placed at 0 m, 10 m, 30 m.
5 sprints with 90 seconds rest in between
Surface to sprint: lawn football pitch
Weather conditions: sunny, dry and pleasant temperature
Height measured barefoot and weight with a digital scale (Seca Alpha)
Conclusions
1. The junior C group was the slowest (p<0.05) and the junior A group was the fastest
2. The differences of the speed averages between group B and C was much more bigger than the differences between the group A and the group B
3. On general, the goalkeepers were the slowest and the forwards were the fastest
4. The top speed was achieved on the final 20 m
5. Maturation might justify the differences
