Small-sided games (SSGs) are common drills used in various team sports, but the exercise intensity in ultimate Frisbee SSG has not yet been investigated. To clarify the physical, physiological, and technical demands of ultimate Frisbee SSG, we investigated the influence of pitch size on exercise intensity during SSG. Nine male college ultimate Frisbee players played (3 vs. 3) SSG on small (SSG_S: 30 × 15 m) and large (SSG_L: 40 × 20 m) pitches; both SSGs comprised of four 4 min periods, interspersed by 5 min of passive recovery. Players’ mean heart rate (170 ± 8 and 171 ± 7 bpm), peak heart rate (184 ± 7 and 184 ± 5 bpm), and blood lactate concentration (11.3 ± 4.7 and 11.8 ± 4.6 mmol/L) were similar in SSG_S and SSG_L, respectively. The total distance covered (1984 ± 166 m and 1702 ± 80 m) and the distance covered during quick (860 ± 112 m and 696 ± 69 m) and high-intensity running (439 ± 95 and 255 ± 44) in SSG_L were significantly longer than those in SSG_S (p < 0.05). Conversely, the number of accelerations (45 ± 3 and 41 ± 3) and decelerations (44 ± 3 and 40 ± 4), catching errors (2 ± 1 and 1 ± 1), and turnovers (8 ± 2 and 6 ± 2) in SSG_S were significantly greater than those in SSG_L (p < 0.05). This study suggests that ultimate Frisbee SSG provides high-intensity training, which stimulates the glycolytic pathway. Furthermore, manipulating SSG pitch size effectively modulates the physical demands of SSG.

极限飞盘小型比赛中的身体、生理和技术要求：间距大小的影响

小型比赛（SSGs）是各种团队运动中常用的练习，但极限飞盘SSG中的运动强度尚未得到调查。为了阐明极限飞盘 SSG 的身体、生理和技术要求，我们调查了 SSG 期间音高大小对运动强度的影响。九名男子大学极限飞盘运动员在小型（SSG _S：30 × 15 m）和大型（SSG _L：40 × 20 m）球场上玩（3 对 3）SSG ；两个 SSG 由四个 4 分钟的时间段组成，中间穿插着 5 分钟的被动恢复。运动员的平均心率（170 ± 8 和 171 ± 7 bpm）、峰值心率（184 ± 7 和 184 ± 5 bpm）和血乳酸浓度（11.3 ± 4.7 和 11.8 ± 4.6 mmol/L）在 SSG 中相似_S和 SSG _L， 分别。SSG _L的总跑距离（1984±166 m和1702±80 m）和快速跑（860±112 m和696±69 m）和高强度跑（439±95和255±44）跑的距离分别为显着长于 SSG _S ( p < 0.05)。反之，加速次数（45±3和41±3）和减速次数（44±3和40±4），接球次数（2±1和1±1），失误次数（8±2和6±2） SSG _S中的显着大于 SSG _L ( p< 0.05)。这项研究表明终极飞盘 SSG 提供高强度训练，刺激糖酵解途径。此外，操纵 SSG 间距大小可以有效地调节 SSG 的物理需求。
