Introduction: Among high intensity trainings, high intensity functional training (HIFT) represent one of the most recent developments. The aim of the present study was to investigate the differences between a group of competitive (CMP) HIFT athletes and a group of age- and gender-matched beginner (BGN) HIFT athletes, to clarify the physiological characteristics of each group and the reasons for differences. Methods: 10 BGN (32.5 ± 6.2 years) and 10 CMP (29.0 ± 5.4 years) athletes, were included in the study and were evaluated for anthropometry, VO 2peak , lactate threshold, isometric and isokinetic leg maximal power and strength, handgrip and maximal anaerobic power. Results: Compared to BGN athletes, CMP reached higher levels of VO 2peak (56.1 ± 2.89 ml·kg -1 ·min -1 CMP vs. 46.5 ± 6.86 ml·kg -1 ·min -1 BGN; p .006), while anaerobic capacity did not show significant differences (101.8 ± 9.33 kJ CMP vs. 87.0 ± 28.37 kJ BGN; p = .1). Conclusions: CMP athletes showed greater physiological adaptations in aerobic fitness and strength than BGN. Differences may be attributed to the technical skills acquired by CMP and not only to the physiological adaptations induced by the specific training. The lack of differences in anaerobic capacity is likely due to an early and fast improvement in BGN, compared to other parameters.

竞技与初级高强度功能训练运动员的生理比较

简介：在高强度训练中，高强度功能训练 (HIFT) 代表了最新的发展之一。本研究的目的是调查一组竞技 (CMP) HIFT 运动员与一组年龄和性别匹配的初学者 (BGN) HIFT 运动员之间的差异，以阐明各组的生理特征及其原因。差异。方法：10 名 BGN（32.5 ± 6.2 岁）和 10 名 CMP（29.0 ± 5.4 岁）运动员被纳入研究，并评估人体测量学、VO 2peak 、乳酸阈值、等长和等速腿部最大力量和力量、握力和最大力量。无氧动力。结果：与 BGN 运动员相比，CMP 达到了更高的 VO 2peak 水平（56.1 ± 2.89 ml·kg -1 ·min -1 CMP vs. 46.5 ± 6.86 ml·kg -1 ·min -1 BGN；p = .006），而厌氧能力没有显示出显着差异（101.8 ± 9.33 kJ CMP vs. 87.0 ± 28.37 kJ BGN；p = .1）。结论：与 BGN 相比，CMP 运动员在有氧健身和力量方面表现出更大的生理适应性。差异可能归因于 CMP 获得的技术技能，而不仅仅是由特定训练引起的生理适应。与其他参数相比，无氧能力没有差异可能是由于 BGN 的早期和快速改善。
