ABSTRACT
Study design: identify a better strategy for static stretching (SS), dynamic stretching (DS), and proprioceptive neuromuscular facilitation (PNF) concerning the performance of their applications in countermovement vertical jump (CVJ). A systematic literature review was conducted in May and June 2021 in the Pubmed/MEDLINE, Scopus, LILACS, SPORTDiscus, and Embase databases. The PRISMA-2020 checklist was used. The Cochrane handbook scale and the Downs and Black scale were used for risk of bias analysis. Seventeen studies were included for qualitative analysis. Motor Unit recruitment and its stimulation frequency favor neural factors and muscle strength performance during contraction. Detailed investigations are necessary on the neural factors that modify the reflex responses and motor control, considering the biological characteristics and plastic deformations. The SS is a negative predictor of vertical jump (VJ) performance. The improvements are reduced when the stretching time is longer than 60 seconds, and when associated with PNF, did not reveal significant results. Using the SS before the DS in short periods of 20 seconds and no more than 60 seconds in the pre-activity to the VJ is suggested. In short stretches, the ROM increased both in the knee and the hip, and the hamstring muscles, when in tension, are unfavorable in sports that frequently use the VJ. Therefore, PNF using the technique that involves a process of contracting and relaxing must be investigated in an isolated and specific way, advocating the antagonist group. Thus, decreasing antagonist strength may be favorable for height gain, although contemporary studies are needed to minimize lower stability and muscle control predictors.
