INTRODUCTION:
It has been reported that continues moving after passing a ball is important for improving the team's performance during a soccer game. We took particular note of the kick motion used to pass a ball during a soccer game in this respect and previously reported that increasing the frequency and rate of the “dynamic kick” using walking and running motions helps enhance soccer players’ competitive abilities. This study explored the characteristics of the type of a kick used to pass a ball during a soccer game from the perspectives of “inside kick” and “instep kick”. Based on video data from 10 soccer matches, the frequency and rate of inside and instep kicks were analyzed, and the differences between a college team, the Asian country national team, and two European country national teams were compared. From the comparison, we investigated the characteristics and technical problems of the kick motion to pass a ball in college soccer team.
METHODS:
To investigate the characteristics and technical problems of the kick motion to pass a ball in college soccer team, the frequency and rate of inside and instep kicks to pass a ball were analyzed based on video data from 10 soccer matches. The type of inside and instep kicks was determined by two researchers with more than fifteen years’ athletic experience in soccer. The frequency of each kick was counted, and the rate calculated as frequency of the inside or instep kick / frequency of passing a ball ×100 (%). Teams of the analysis object were a college team (CO), the Asian country national team (AN), and two European country national teams (EN1, EN2), and the differences between CO, AN, EN1, and EN2 for 90 minutes during the soccer games were compared.
RESULTS:
The frequency of passing a ball for 90 minutes were 280 in the CO, 447 in the AN, 373 in the EN1, and 530 in the EN2. The frequency and rate of inside kick were 140 and 50% in the CO, 358 and 80% in the AN, 301 and 81% in the EN1, 427 and 81% in the EN2. The frequency and rate of instep kick were 109 and 39% in the CO, 48 and 11% in the AN, 38 and 10% in the EN1, 48 and 9% in the EN2. The frequency and rate of inside kick was lowest and instep kick highest in the CO, compared with the national teams of each country.
CONCLUSION:
Results reveal that the college soccer team had the lowest frequency and rate of inside kick and the highest frequency and rate of instep kick compared with those of national teams. These results suggest that increasing the frequency and rate of the inside kick to pass a ball during a soccer game is important for the college soccer team, and essential for improving one’s skills in the dynamic kick using walking and running motions.
