Table 5.
Number of subjects preexercise that were found to have the condition (n =36) | Number of subjects post marathon that were found to have the condition (n =36) | |
---|---|---|
Bilateral crackles (end‐inspiratory crackles) | 0 | 0 |
Cough, productive of frothy, or blood‐tinged sputum | 0 | 0 |
Third heart sound (S3 gallop rhythm) | 0 | 0 |
Mean (SD) Preexercise | Mean (SD) Post exercise | |
---|---|---|
Arterial oxyhemoglobin saturation via pulse oximetry (%) (n =31) | 98.2 (0.8) | 97.7 (1.2)1 |
Heart rate (beats/min) (n =33) | 60 (9) | 94 (12)1 |
Systolic blood pressure (mmHg) (n =33) | 129 (10) | 120 (10)1 |
Diastolic blood pressure (mmHg) (n =33) | 77 (7) | 76 (8) |
Modified Borg scale for perceived dyspnea (n =36) | 0 (0) | 1 (1)1 |
The modified Borg scale of perceived dyspnea (0 = nothing at all, 2 = slight, 4 = somewhat severe, 6 = very severe, 10 = the most severe out of breath you could ever imagine). The postrace measurements were taken 16 (SD 7) minutes after marathon completion.
Postmarathon values are significantly different compared to premarathon (P <0.05).
