  FIGURE 1. Participant Flow Diagram legend. This flow diagram illustrates the selection process and distribution of participants in the study. From an initial cohort of 13,670 athletes, 1,587 were excluded based on specific criteria. The remaining 12,083 eligible participants underwent either a stress test (n = 9,236) or a cardiopulmonary exercise test (n = 2,847). All 12,083 participants were included in the final analysis. This diagram provides a clear overview of the study population from initial recruitment to final data analysis.

  FIGURE 2. Standardized Coefficients of Predictors of Peak Systolic Blood Pressure in Athletes. legend This figure displays the standardized coefficients (β) from a multivariate regression analysis examining the relationship between peak systolic blood pressure (SBPpeak) and several demographic and resting parameters in a cohort of athletes undergoing preparticipation testing. The standardized coefficients represent the relative strength and direction of each predictor’s association with SBPpeak, with larger absolute values indicating a stronger relationship. Green bars indicate highly significant positive predictors (p < .001), yellow bars indicate significant positive predictors (p < 0.01 and p < 0.05), and red bars indicate non-significant predictors (p > 0.05). Resting systolic blood pressure, height, workrate, and age were the strongest predictors of SBPpeak in this athlete cohort.

  FIGURE 3. Comprehensive Analysis of Systolic Blood Pressure Responses Across Age and Sex in Athletes During Exercise. General Legend for All Panels: Each panel displays clustered box plots of raw or indexed systolic blood pressure (SBP) responses, categorized by age and sex. Within each box plot, the “X” marks the mean, while the median is represented by a line. Outliers are shown as individual dots. Linear trends connecting the means for both sexes across age categories illustrate changes in SBP response patterns. Specific Legends for Each Panel: Panel (A) Shows the peak exercise systolic blood pressure (SBPpeak) across different age groups, separated by sex, highlighting how cardiovascular responses vary during exercise. Panel (B) Illustrates the SBP/WR slope, indicating the rate of change in SBP relative to workload increases. It shows a steeper increase in SBP with increasing workload, particularly in females across all age groups. Panel (C) Focuses on the SBP/WR ratio, which quantifies the normalized systolic blood pressure response to workload. This panel points to higher values in females across all age groups, suggesting a more pronounced response. Panel (D) Presents the SBP/(W/kg)…
