Furthermore, the aim of the quantitative analysis was to verify and objectivize the impact of these variables on athlete\u2019s body posture. A search of electronic database (PubMed, EBSCO, MEDLINE) was conducted to identify all studies on sports training and athlete\u2019s spine and body posture from 2011 to 2021. In the sagittal plane, the pooled proportion accounted for 44.97% (95% CI 31.22\u201358.72%) for thoracic hyperkyphosis (TH), 4.98% (95% CI 1.60\u20138.36%) for lumbar hyperlordosis (hyperLL), and 12.35% (95% CI 1.60\u20138.36%) for lumbar hypolordosis (hypoLL). Furthermore, in the sagittal plane, the pooled mean of thoracic kyphosis angle was 37.59\u00b0 (95% CI 34.45\u201340.73%), whereas lumbar lordosis angle was 29.79\u00b0 (95% CI 26.46\u201333.12%). Professional athletes tend to have postural disturbances and\/or spinal curvature disorders in the sagittal and frontal planes.
