Background

Some health benefits from high-intensity interval training (HIIT) are facilitated by peripheral blood lactate levels. However, the lactate response from HIIT is variable and dependent on protocol parameters.

Objectives

We aimed to determine the HIIT protocol parameters that elicited peak lactate levels, and how these levels are associated with post-HIIT cognitive performance.

Study Design

We conducted a systematic review with meta-regression.

Methods

MEDLINE, Embase, CENTRAL, SPORTDiscus, and CINAHL + were searched from database inception to 8 April, 2022. Peer-reviewed primary research in healthy adults that determined lactate (mmol/L) and cognitive performance after one HIIT session was included. Mixed-effects meta-regressions determined the protocol parameters that elicited peak lactate levels, and linear regressions modelled the relationship between lactate levels and cognitive performance.

Results

Study entries (n = 226) involving 2560 participants (mean age 24.1 ± 4.7 years) were included in the meta-regression. A low total work-interval volume (~ 5 min), recovery intervals that are about five times longer than work intervals, and a medium session volume (~ 15 min), elicited peak lactate levels, even when controlling for intensity, fitness (peak oxygen consumption) and blood measurement methods. Lactate levels immediately post-HIIT explained 14–17% of variance in Stroop interference condition at 30 min post-HIIT.

Conclusions

A HIIT protocol that uses the above parameters (e.g., 8 × 30-s maximal intensity with 90-s recovery) can elicit peak lactate, a molecule that is known to benefit the central nervous system and be involved in exercise training adaptations. This review reports the state of the science in regard to the lactate response following HIIT, which is relevant to those in the sports medicine field designing HIIT training programs.

高强度间歇训练方案对健康成人血乳酸水平和认知的影响：系统评价和元回归

背景

外周血乳酸水平促进了高强度间歇训练 (HIIT) 带来的一些健康益处。然而，HIIT 对乳酸的反应是可变的，取决于协议参数。

目标

我们的目的是确定引发峰值乳酸水平的 HIIT 协议参数，以及这些水平如何与 HIIT 后认知表现相关联。

学习规划

我们使用元回归进行了系统回顾。

方法

MEDLINE、Embase、CENTRAL、SPORTDiscus 和 CINAHL + 的搜索时间从数据库开始到 2022 年 4 月 8 日。包括在健康成人中确定一次 HIIT 训练后的乳酸 (mmol/L) 和认知表现的同行评审初步研究。混合效应元回归确定了引发峰值乳酸水平的方案参数，线性回归模拟了乳酸水平与认知表现之间的关系。

结果

元回归中包含涉及 2560 名参与者（平均年龄 24.1 ± 4.7 岁）的研究条目 ( n = 226)。较低的总工作间歇量（~ 5 分钟）、比工作间隔长约五倍的恢复间隔和中等训练量（~ 15 分钟），即使在控制强度、健身（峰值）时，也会引发峰值乳酸水平耗氧量）和血液测量方法。HIIT 后立即产生的乳酸水平解释了 HIIT 后 30 分钟 Stroop 干扰条件下 14-17% 的差异。
