Utjecaj broja dodira s loptom na fizičke i fiziološke zahtjeve velikih pomoćnih nogometnih igara

The main aim of the study was to evaluate the relation between the number of ball touches for individual possession and physical/physiological demands during the large-sided soccer games (LSGs) of 7 vs. 7 players plus goalkeepers. During the exercise, the number of assigned touches for individual possession (1-touch, 2-touch and free-touch) was altered. Fourteen amateur soccer players (age: 24.4±4.7 years; height: 180±5.6 cm; weight: 77.9±5.6 kg) were monitored during exercise with 10 Hz GPS devices and heart rate (HR) monitors. The following variables were recorded: HR responses, total distance covered, distance covered in different speed ranges (0–6.9, 7.0–12.9, 13.0–17.9, 18.0–20.9 and >21 km·h–1), player load and number of accelerations. The number of ball touches altered physical and physiological demands during exercise. Higher HR responses and greater distances covered were recorded during the free-touch assignment (p<.05). No significant differences were found in 1-touch and 2-touch protocols. These results may help coaches to modify different variables in LSGs concerning physical and physiological demands of soccer.Glavni je cilj ovog istraživanja bio vrednovati odnos između broja dodira s loptom tijekom pojedinog posjeda i fizičkih/fizioloških zahtjeva za vrijeme igranja velikih pomoćnih igara u kojima igra po sedam igrača i vratar u svakoj ekipi. Tijekom igre su istraživači mijenjali broj zadanih dodira s loptom tijekom svakog pojedinačnog posjeda (jedan dodir, dva dodira, slobodan broj dodira). U istraživanje je bilo uključeno četrnaest nogometaša amatera (dob: 24,4 ± 4,7 godina; visina: 180 ± 5,6 cm; težina: 77,9 ± 5,6 kg) koji su tijekom igre bili praćeni pomoću GPS uređaja (10 Hz) i monitora srčane frekvencije. Zabilježene su sljedeće varijable: frekvencija srca, ukupna pretrčana udaljenost, udaljenost pretrčana različitim brzinama (0–6.9, 7.0–12.9, 13.0–17.9, 18.0–20.9 i >21 km·h–1), opterećenje igrača te broj ubrzanja. Istraživanje je pokazalo da broj dodira s loptom predstavlja različite fizičke i fiziološke zahtjeve igre. Veća frekvencija srca i veća pretrčana udaljenost bile su zabilježene tijekom igre sa slobodnim brojem dodira (p
