The focus of this study is to explore the regulation of blood pressure (BP), its diurnal rhythm, and the association with renal impairment in athletes with chronic kidney disease. Given the high physical demands and unique physiological stressors faced by athletes, understanding these dynamics is crucial. The study categorized chronic kidney disease patients treated at our hospital into three groups based on their BP rhythm: dipper BP, non-dipper BP, and anti-dipper BP. A retrospective analysis was conducted on the general condition of these patients and their bedrest BP values, examining correlations with kidney function. Findings revealed significant differences in diurnal diastolic BP (dDBP), nocturnal systolic BP (nSBP), and nocturnal pulse pressure variation (P<0.05). The study concludes that most athletes with chronic nephropathy exhibit non-dipper and anti-dipper BP rhythms. Notably, abnormal diurnal BP patterns, elevated nocturnal pulse pressure variation, and high diastolic BP were all linked to renal impairment. These findings suggest that bedrest BP provides comprehensive insights into an athlete's BP profile, aiding in targeted treatments to slow kidney function decline and reduce the risk of cardiovascular and cerebrovascular events. Understanding these patterns is essential for optimizing the health and performance of athletes managing chronic nephropathy.
