The aim of this study was to investigate the effect of field length on physiological and external load in the same field area during small-sided games (SSGs) of soccer. Three field dimensions were used for SSGs: (1) wide field (wide; 20 × 30 m), (2) normal field (normal; 30 × 20 m), and (3) long field (long; 40 × 15 m). Eight college soccer players (average age: 21 ± 1 yr; height: 171.5 ± 2.9 cm; body mass: 66.9 ± 2.0 kg) were monitored using a heart rate monitor and a 18.18 Hz GPS device. Total distance, distance covered in four speed categories, maximum heart rate, and spend time in four heart rate zone categories were included in the analysis. Moreover, %Sprint. Vmax — defined as the peak sprinting speed during SSGs relative to the individual maximum sprinting speed measured in the prior 60 m sprint test—was included in the assessment. Statistically significant differences in total distance and %Sprint. Vmax were observed under the long condition; however, no significant differences were observed in the remaining measures. Study findings supported that for the same field area per player, extending field length increased total distance and sprinting speed during SSGs.
