    Summary

    A four-week endurance running program improved cardiovascular health in patients, lowering blood pressure and increasing maximal oxygen intake (VO2 max). This training is effective for improving physical condition during cardiac rehabilitation.

    Area of Science:

    • Cardiology
    • Exercise Physiology
    • Rehabilitation Medicine

    Background:

    • Cardiac rehabilitation programs aim to improve cardiovascular health and physical function in patients with heart conditions.
    • Understanding the impact of specific training regimens on physiological markers is crucial for optimizing patient outcomes.

    Purpose of the Study:

    • To assess the effects of a four-week endurance running program on cardiovascular parameters at rest and during submaximal exercise.
    • To determine the optimal training intensity and duration for patients undergoing cardiac rehabilitation.

    Main Methods:

    • 144 patients (average age 47.1 years) participated in a four-week cardiac rehabilitation program.
    • Physiological assessments included heart rate variability, blood pressure, and maximal oxygen intake (VO2 max) via ergometry.
    • Training involved daily 60-minute perseverance runs at approximately 50% VO2 max.

    Main Results:

    • Significant bradycardia (slower heart rate) and improved physical fitness (increased VO2 max) were observed.
    • Initially elevated systolic and diastolic blood pressure values decreased.
    • Cardiac volume remained unchanged after the four-week intervention.

    Conclusions:

    • A four-week endurance running program effectively enhances cardiovascular function and physical capacity in patients undergoing cardiac rehabilitation.
    • Daily 60-minute training at 50% VO2 max is an effective, applicable, and dosable intervention, particularly for older and less conditioned individuals.
    • While physiological function improves, cardiac size does not significantly alter within this timeframe.
