Key result
Hypertension in male marathoners is linked to ~8-minute longer daily exercise durations.
Why the study?
Are excessive exercise characteristics associated with high blood pressure in middle-aged recreational male marathoners?
Case-Control (n=571)
Are excessive exercise characteristics associated with high blood pressure in middle-aged recreational male marathoners?
Absolute Event Rate: 101.3% vs 93.7%
p-value: p=<0.05
Excessive exercise characteristics, such as longer marathon history and higher intensity, are associated with high blood pressure in middle-aged male marathoners and may serve as indicators of masked hypertension.
May flag masked hypertension in intensely training male marathoners; hypothesis-generating and requires prospective confirmation before clinical adoption.
Background . Excessive exercise such as marathon running increases the risk of cardiovascular events that may be related to myocardial infarction and sudden death. We aimed to investigate that the exercise characteristics can be used as a novel indicator of masked hypertension. Methods . A total of 571 middle-aged recreational male marathoners were assigned to a high blood pressure group (HBPG; n=214) or a normal blood pressure group (NBPG; n=357). A graded exercise test was used to examine the hemodynamic response and cardiac events, and the personal exercise characteristics were recorded. Results . Systolic blood pressure and diastolic blood pressure were higher in the HBPG than in the NBPG (p<0.05, all). The marathon history, exercise intensity, and time were longer and higher, whereas the marathon completion duration was shorter in the HBPG than in NBPG (p<0.05, all). HBPG showed a higher frequency of alcohol consumption than NBPG (p<0.05). Conclusion . More excessive exercise characteristics than the normative individuals. If the individuals exhibit high blood pressure during rest as well as exercise, the exercise characteristics could be used as a novel indicator for masked hypertension.

Kim et al. (2017) conducted a case-control in Masked hypertension (n=571). High blood pressure (HBPG) vs. Normal blood pressure (NBPG) was evaluated on Exercise duration (min/day) (p=<0.05). Middle-aged male marathoners with high blood pressure exhibited more excessive exercise characteristics, such as significantly longer exercise durations and higher exercise intensities, compared to those with normal blood pressure.
