The aim of the present study was to compare combined small‐sided game (SSG) and high‐intensity interval training (HIT) with different order. Twenty‐one semi‐professional soccer players were divided into two groups: SSG+HIT (n = 10) and HIT+SSG (n = 11), and underwent similar four‐week training programs. Players completed the 30‐15 Intermittent Fitness Test (30‐15IFT) before and after the experiment; maximum speed (VIFT) was recorded. During the experiment, seven sessions of SSG (3 vs 3) and HIT (15ʺ‐15ʺ with 95‐100% VIFT) were implemented. Weekly accumulated training loads for both groups during the experiment were similar. Moderate improvements in VIFT were observed in both SSG+HIT (+6.2%, 90% confidence limits, [CL] 4.6; 7.7 and Effect Size, [ES] +0.96) and HIT+SSG (+6.9%, 90% CL 4.6; 9.3 and ES +0.97) groups. Between‐group difference in changes of VIFT was trivial (+0.7%, 90% CL ‐1.8; 3.3 and ES +0.11). Combining SSG and HIT in different order elicited the same enhancement in high‐intensity intermittent performance in soccer players.
