ABSTRACT
Ballon d'Or is the most important individual award in football, and is a significant measure of excellence. From our knowledge, this is the first study that explored the relative age effect (RAE) throughout the history of the Ballon d'Or. A total of 1899 football players nominated for the award from the first edition in 1956 to the most recent edition (2023) were analyzed. To assess the RAE, the birthdate distributions were categorized into four trimesters. The comparison involved correcting for the uniform distribution using chi-square analysis, with Cramer's V serving as a measure of effect size. Standardized residuals were computed to identify quarters that exhibited significant deviation from the expected values. Odds Ratio and 95% confidence intervals were used to identify discrepancies between trimesters. The results indicated a pronounced presence of an RAE at the global level. However, the longitudinal analysis revealed variations in the behavior of the RAE over time. In the initial decades, there is an overrepresentation of players born in the last months of the year. Subsequently, there is no discernible RAE. In the most recent decades, there has been a clear resurgence of RAE, with an overrepresentation of players born in the first quarters of the year.
ABSTRACT
BACKGROUND: The progression of Parkinson's Disease is variable, leading to a poor pharmacological response, as the effect of medication is reduced due to adaptation. Physical therapy is established as adjuvant treatment on physical conditions. The aim of this study was to monitor the level of physical fitness and anthropometric parameters of patients diagnosed with Parkinson's Disease, who had participated in physical exercise programs for 8-years. METHODS: Seventy-one patients diagnosed with Parkinson's disease (53.50% males), mean age 71.19±9.04 years old, with a mean disease stage of 2.52±0.77 (Hoehn and Yahr Scale). All patients underwent an assessment of fitness and body composition at baseline (2011), 4-years, and 8-years. RESULTS: The study of the anthropometric parameters showed that throughout the 8 years of follow-up, the BMI has not undergone significant changes and shows a small upward trend for both men (0.30%, sig=0.938) and women (-0.10%, sig=0.817). This same behavior was reflected by the weight in men (1.36%, sig=0.315) and in women (-0.35%, sig=0.787). In terms of physical fitness, men showed a trend towards a deterioration in this parameter over the 8 years of follow-up (ΣFitness=-1.82%, sig=0.930), while women showed a trend towards improvement (ΣFitness=0.96%, sig=0.821). The same is recorded for strength and flexibility, where the data suggest that these are two of the variables that deteriorated the most over the 8 years of the study. CONCLUSIONS: After an 8-year follow-up, no significant changes in FC parameters affected by the progression of a neurodegenerative disease such as Parkinson's disease have been identified. The 8-foot up and go test has shown correlations with the other physical tests used.
