The purpose of the present study was to compare the influence of an acute bout of high-intensity functional training (HIFT) with an acute bout of moderate-intensity continuous training (MICT) on measures of cognitive function.
Sixty-nine young adults (Mean ± SD: age 21.01 ± 2.79 yrs; body mass 69.65 ± 6.62 kg; height 1.74 ± 0.05 m; Body Mass Index 22.8 ± 1.41) gave informed consent and were randomly divided into three groups. The HIFT group, with 27 participants, performed a high-intensity (>85% Max. HR) circuit of functional exercises for 30 min. The MICT group, with 28 participants, performed moderate-intensity (70-80% Max. HR) continuous training on a cyclo-ergometer. The control group did not perform any activity. The Stroop Test, Word Recall and N-Back Test were completed to assess during the familiarization period, immediately before and immediately after the training's bouts.
The repeated measures ANOVA did not show significant mean differences for any group. However, the T-Test for the paired samples demonstrated very significant differences in the Stroop Test, in terms of fastest response time (FRT; mean difference (MD) -1.14, 0.01, d 0.9), mean response time (MRT; MD -2.16, 0.01, d 0.66) and the number of correct answers (NCA; MD 1.08, 0.05, d 0.5) in the HIFT group and in the MICT group (FRT; MD -1.79, 0.01, d 0.9), (MRT; MD -3.07, 0.01, d 0.9) (NCA; MD 1.54, 0.05, d 0.5).
There were no differences in the control group. HIFT and MICT may elicit specific influences on cognitive function, mainly in executive function and selective attention.
本研究的目的是比较高强度间歇功能训练（HIFT）与中等强度持续训练（MICT）急性运动对认知功能的影响。
69 名年轻成年人（平均 ± 标准差：年龄 21.01 ± 2.79 岁；体重 69.65 ± 6.62kg；身高 1.74 ± 0.05m；体重指数 22.8 ± 1.41）知情同意并随机分为三组。HIFT 组 27 名参与者进行了 30 分钟的高强度（>85%最大心率）功能性运动循环。MICT 组 28 名参与者在固定式自行车上进行中等强度（70-80%最大心率）持续训练。对照组不进行任何活动。Stroop 测试、单词回忆和 N-Back 测试在熟悉阶段、训练前后立即完成。
重复测量方差分析显示，任何组都没有显著的平均差异。然而，配对样本 T 检验表明，HIFT 组和 MICT 组的 Stroop 测试在最快反应时间（FRT；平均差值（MD）-1.14，0.01，d0.9）、平均反应时间（MRT；MD-2.16，0.01，d0.66）和正确答案数（NCA；MD 1.08，0.05，d0.5）方面存在非常显著差异。
对照组没有差异。HIFT 和 MICT 可能对认知功能产生特定影响，主要是在执行功能和选择性注意方面。
