Figure 5
Decreased exercise capacity of a 19-year-old female water polo player after SARS-CoV-2 infection. On the graph, two CPET examinations are shown, between the two exanimations the follow-up time was 0.61 year. The earlier results of the examinations are shown with pale colours, the examinations after the SARS-CoV-2 are shown with sharp lines. The athlete achieved shorter running time on the same CPET protocol, with approximately the same ventilation (brown lines), slightly higher oxygen uptake (blue lines) and carbon dioxide production (red lines), worse metabolic adaptation to sports activity, which is represented by the increased lactate levels (green lines). The aerobic and anaerobic thresholds are represented with two vertical lines during the post-infection examination. In conclusion, multiple negative effects on her fitness status can be observed in this case. Further examinations revealed the worsening of her previously known asthma bronchiale symptoms and her treatment was optimized. Abbreviations: VO2, oxygen uptake; VE, ventilation; VCO2, carbon-dioxide production.
