Main Physiological, Clinical and Physical Performance Aspects of Ischemic preconditioning in the Musculoskeletal System
ischemic preconditioning; perceived exertion; exercise; soccer
Introduction: Ischemic preconditioning (IPC) is a method that has been widely used
to improve performance acutely and prevent muscle fatigue in different modalities of
physical exercise. Despite several physiological dispositions for performance
improvement, evidence on the effects of IPC is conflicting. Some studies suggest that
IPC improves muscle function, while others suggest that IPC is not superior to sham.
Objectives: This thesis aimed to investigate the psychophysiological, functional and
neuromuscular effects of IPC. Methods: For this thesis, the application of IPC
locally, without the combination with physical exercise, was considered. There was no restriction on gender, age or conditions for the public, in addition to encompassing various exercise modalities (aerobic, anaerobic, intermittent) and mental and neuromuscular tests. Results: Chapter 1 deals with the effects of IPC on functional and neuromuscular performance in amateur soccer players, containing two articles: a clinical trial protocol and the randomized clinical trial. In chapter 2, comment on the effects of IPC on the subjective perception of exertion, containing two articles as well: a systematic review protocol and a systematic review. In chapter 1, it was verified whether the IPC would improve functional and neuromuscular performance in the lower limbs of amateur soccer players. It was observed that there was no difference between the group that performed the IPC and the sham for any of the variables. In chapter 2, the effect of IPC on RPE in different physical tests and sports modalities was investigated. Evidence from this review indicated that there was no difference in PSE between the IPC group and the comparison group. Conclusions: In general, the use of IPC was not superior to the control (sham or no intervention) in improving the functional or neuromuscular performance of amateur soccer players or in attenuating the subjective perception of training in different modalities and modalities.
