Low-volume, time-efficient high-intensity interval training (HIIT), which involves whole-body (WB) callisthenics exercises, has gained worldwide popularity in recent years. However, the physiological and perceptual impact of WB-HIIT in comparison to specialised, equipment-based training is relatively less studied. This study compared the acute physiological and perceptual responses to a single session of WB-HIIT, ergometer-based HIIT (ERG-HIIT) and conventional moderate-intensity continuous training (MICT). Fourteen physically inactive adults (age: 28.4 ± 6.5 years, VO: 31.0 ± 6.2 mL· kg· min) underwent three main trials (WB-HIIT: 12 x 30-s high-intensity callisthenics workout; ERG: HIIT: 12 x 30-s high-intensity cycling bouts; MICT: 30-min cycling at 50% peak power output) in a randomized cross-over order 3-7 days apart. The mean session heart rate (HR) and perceived exertion were comparable across all three protocols ( > 0.05). WB-HIIT attained a similar peak HR (87.4 ± 9.4 %HR) as that of ERG-HIIT (83.0 ± 8.6 %HR), and significantly greater than that of MICT (78.7 ± 5.5 %HR, = 0.001). However, WB-HIIT induced significantly higher blood lactate levels (7.2 ± 1.8 mmol/L) compared to both ERG-HIIT (5.1 ± 1.3 mmol/L, < 0.05) and MICT (3.1 ± 1.5 mmol/L, < 0.001). The participants reported higher self-efficacy and greater enjoyment with WB-HIIT compared to MICT ( < 0.05). The mean HR and perceived exertion responses to WB-HIIT are comparable to those of equipment-based HIIT and MICT; however, WB-HIIT results in greater metabolic strain than both other modalities. Despite this, the overall perceptual responses to WB-HIIT are positive, suggesting that it could be a viable exercise alternative, especially for individuals with limited exercise time and restricted access to facilities and equipment.
低容量、省时高效的高强度间歇训练（HIIT），包括全身（WB）体操练习，近年来在全球范围内广受欢迎。然而，与专门的、基于设备的训练相比，WB-HIIT 的生理和感知影响相对研究较少。本研究比较了单次 WB-HIIT、基于测功计的 HIIT（ERG-HIIT）和常规中等强度持续训练（MICT）的急性生理和感知反应。14 名身体不活跃的成年人（年龄：28.4±6.5 岁，VO：31.0±6.2mL·kg·min）在 3-7 天的时间内，以随机交叉顺序进行了三次主要试验（WB-HIIT：12 次 30 秒高强度体操锻炼；ERG：HIIT：12 次 30 秒高强度自行车运动；MICT：50%峰值功率输出下 30 分钟自行车运动）。所有三种方案的平均运动心率（HR）和感知用力都相当（>0.05）。WB-HIIT 达到的峰值 HR（87.4±9.4%HR）与 ERG-HIIT（83.0±8.6%HR）相似，显著高于 MICT（78.7±5.5%HR， =0.001）。然而，WB-HIIT 诱导的血乳酸水平（7.2±1.8mmol/L）明显高于 ERG-HIIT（5.1±1.3mmol/L， <0.05）和 MICT（3.1±1.5mmol/L， <0.001）。与 MICT 相比，参与者报告 WB-HIIT 的自我效能感和愉悦感更高（<0.05）。WB-HIIT 的平均 HR 和感知用力反应与基于设备的 HIIT 和 MICT 相当；然而，WB-HIIT 比其他两种方式产生更大的代谢应激。尽管如此，WB-HIIT 的整体感知反应是积极的，这表明它可能是一种可行的运动替代方案，特别是对于那些时间有限且无法使用设施和设备的人。
