This study compared the physiological profiles and energy-system contributions of trained football players engaged in regular-passing and third-man-passing small-sided games (SSGs) that included 4 versus 4 and a goalkeeper.
Ten male trained football players participated in this crossover study. All participants were randomly assigned to either regular-passing SSG or third-man-passing SSG (4 vs 4 with a goalkeeper, 35-m × 17-m pitch size, and 6-min match duration). During these SSGs, physiological parameters including peak and mean heart rate, oxygen uptake (V˙O2peak and V˙O2mean), metabolic equivalents in V˙O2peak and V˙O2mean, and blood lactate concentrations (peak La- and delta La- [Δ La-]), were measured. Energy contributions (oxidative [WOxi], glycolytic [WGly], and phosphagen [WPCr] systems) and Global Positioning System (GPS) variables (total distance, total acceleration counts, mean speed, and maximum speed) were also analyzed.
No significant differences in physiological parameters and GPS variables were found between regular- and third-man-passing SSGs. WOxi in kilojoules and percentages was significantly higher during both SSGs than WPCr and WGly (P < .0001, respectively). WPCr and WPCr + WGly values during third-man-passing SSGs were significantly higher than those during regular-passing SSGs (P < .05). Additionally, low to moderate positive correlations were observed between WOxi, WGly in kilojoules, V˙O2peak, V˙O2mean, peak La-, Δ La-, total acceleration counts, and mean speed (r = .39-.64).
Third-man-passing SSGs may be useful for increasing anaerobic capacity. More third-man-passing SSG sessions in preparation for football games may support high metabolic power and repeated powerful anaerobic performances in trained football players.
本研究比较了在包含 4 对 4 和守门员的常规传球和第三人传球小场比赛（SSG）中，接受过训练的足球运动员的生理特征和能量系统贡献，这两种 SSG 分别为常规传球 SSG 和第三人传球 SSG。
10 名男性经过训练的足球运动员参与了这项交叉研究。所有参与者均随机分配至常规传球 SSG 或第三人传球 SSG（4 对 4 有守门员，35 米×17 米场地大小，6 分钟比赛时长）。在这些 SSG 中，测量了包括峰值和平均心率、摄氧量（峰值和平均 V˙O2）、峰值和平均 V˙O2 的代谢当量、血乳酸浓度（峰值和Δ La-）在内的生理参数。还分析了能量贡献（氧化 [WOxi]、糖酵解 [WGly] 和磷酸肌酸 [WPCr] 系统）和全球定位系统（GPS）变量（总距离、总加速次数、平均速度和最大速度）。
在常规传球和第三人传球 SSG 之间，生理参数和 GPS 变量没有显著差异。在两种 SSG 中，WOxi 以千焦耳和百分比表示，均显著高于 WPCr 和 WGly（分别为 P<0.0001）。第三人传球 SSG 中的 WPCr 和 WPCr+WGly 值明显高于常规传球 SSG（P<0.05）。此外，WOxi、千焦耳 WGly、V˙O2peak、V˙O2mean、峰值 La-、Δ La-、总加速次数和平均速度之间观察到低到中度正相关（r = 0.39-0.64）。
第三人传球 SSG 可能有助于提高无氧能力。在为足球比赛做准备时，增加第三人传球 SSG 的次数可能会支持训练有素的足球运动员的高代谢功率和反复的强大无氧表现。
