COMPARING THE PHYSICAL DEMANDS OF FRIENDLY MATCHES AND SMALL-SIDED GAMES IN SEMIPROFESSIONAL SOCCER PLAYERS

Casamichana, D, Castellano, J, and Castagna, C. Comparing the physical demands of friendly matches and small-sided games in semiprofessional soccer players. J Strength Cond Res 26(3): 837-843, 2012-This study compared the physical demands of friendly matches (FMs) and small-sided games (SGs) in semiprofessional soccer players by means of global positioning system technology. Twenty-seven semiprofessional soccer players were monitored during 7 FMs and 9 sessions involving different SGs. Their physical profile was described on the basis of 20 variables related to distances and frequencies at different running speeds, the number of accelerations, and through global indicators of workload such as the work: rest ratio, player workload, and the exertion index. Results showed significant differences (p < 0.01) between SGs and FMs for the following variables: overall workload (SG > FM); the distribution of the distance covered in the speed zones 7.0-12.9 km.h(-1) (SG > FM) and >21 km.h(-1) (FM > SG); the distribution of time spent in certain speed zones (FM > SG: 0.0-6.9 and >21 km.h(-1); FM > SG: 7.0-12.9 km.h(-1)). More sprints per hour of play were performed during FMs, with greater mean durations and distances, greater maximum durations and distances, and a greater frequency per hour of play for sprints of 10-40 and >40 m (p < 0.01). The frequency of repeated high-intensity efforts was higher during FM (p < 0.01). The results show that coaches and strength and conditioning professionals should consider FMs during their training routine to foster specific adaptations in the domain of high-intensity effort.
