Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment High-Intensity Interval Nordic Walking for Coronary Artery Disease?

Research shows that Nordic walking, when combined with standard cardiac rehabilitation, improves physical activity levels, aerobic efficiency, and quality of life in patients with coronary artery disease. It also positively affects certain risk factors for heart disease, making it a more effective therapy than standard cardiac rehabilitation alone.12345

Is High-Intensity Interval Nordic Walking safe for people with coronary artery disease?

High-Intensity Interval Training (HIIT), which includes High-Intensity Interval Nordic Walking, has shown a low rate of major adverse cardiovascular events in patients with coronary artery disease when used in cardiac rehabilitation settings, with only one major event occurring per 17,083 training sessions.12456

How is high-intensity interval Nordic walking different from other treatments for coronary artery disease?

High-intensity interval Nordic walking is unique because it combines the benefits of high-intensity interval training (HIIT) with the full-body engagement of Nordic walking, which uses poles to work more muscle groups. This approach not only improves cardiovascular health but also enhances functional capacity and quality of life, making it a novel option compared to traditional exercise therapies.12357

What is the purpose of this trial?

Coronary revascularization, such as heart bypass surgery (CABG) and percutaneous coronary intervention (PCI \[inserting a stent to open up blood vessels\]) improve survival for people with coronary artery disease. Yet, many patients suffer from poor physical and mental health after coronary revascularization. Traditional cardiac rehabilitation involving moderate-to-vigorous intensity continuous training (MICT) improves physical and mental health. However, alternative exercise programs, such as high-intensity interval training (HIIT) and Nordic walking may provide superior benefits. Nordic walking is like Nordic skiing but uses specifically designed poles for walking. Nordic walking involved core, upper and lower body muscles, resulting in greater energy expenditure while reducing loading stress at the knee. To date, HIIT used in cardiac rehabilitation settings has focused on lower body (e.g., leg cycling). The investigators are not aware of HIIT protocols that target both upper and lower body at the same time. An exercise program that combines HIIT and Nordic walking (HIIT-NoW) may offer an alternative time-efficient whole-body exercise to improve physical and mental health. This study will test if HIIT-NoW can be an alternative exercise option to improve physical and mental health in patients with coronary artery disease.

Findings from Research

Nordic walking (NW) in patients rehabilitated after coronary events demonstrated an exercise intensity of 59% of their VO₂ reserve, indicating it is a safe and effective form of endurance training in cardiac rehabilitation.
The peak heart rate during NW reached similar levels to those observed during treadmill cardiopulmonary exercise tests, suggesting that NW can provide comparable cardiovascular benefits as traditional exercise testing.
Oxygen uptake during Nordic walking training in patients rehabilitated after coronary events.Rybicki, JR., Leszczyńska-Bolewska, BM., Grochulska, WE., et al.[2017]
The study found that the Polar H7, an ECG-based heart rate monitor, showed excellent accuracy in measuring heart rate during both Nordic and conventional walking, with a high concordance correlation coefficient of 0.96 compared to the reference ECG.
In contrast, the Fitbit Charge 2, which uses photoplethysmography, was less accurate during Nordic walking, showing a significantly higher mean absolute difference in heart rate measurements compared to the Polar H7, indicating that ECG-based devices are preferable for monitoring heart rate in this exercise method.
Accuracy of Wearable Devices for Measuring Heart Rate During Conventional and Nordic Walking.Baek, S., Ha, Y., Park, HW.[2021]
A 12-week exercise program of high-intensity interval training (HIIT), moderate-to-vigorous intensity continuous training (MICT), or Nordic walking (NW) led to significant improvements in functional capacity, quality of life, and depression symptoms in patients with coronary artery disease, with effects sustained up to 26 weeks after the program.
Nordic walking was particularly effective, resulting in a greater increase in functional capacity (measured by the 6-minute walk test) compared to HIIT and MICT, suggesting it may be a superior option for enhancing physical performance in these patients.
