New research suggests that high-intensity exercise, particularly short sprint intervals, may be more effective than moderate-intensity workouts at improving several aspects of cardiovascular and metabolic health.
Researchers have increasingly focused on identifying the types of physical activity that can provide the greatest benefits for cardiometabolic health, which refers to the interconnected health of the heart, blood vessels and the body’s metabolic system.
The cardiovascular system plays an important role in delivering oxygen-rich blood throughout the body. Efficient circulation can also influence how effectively mitochondria inside cells use nutrients to produce energy. A healthy cardiovascular system additionally supports the transport of hormones and glucose and helps remove waste products from the body.
Previous research has linked poor cardiometabolic health with an increased risk of conditions such as type 2 diabetes, chronic kidney disease and fatty liver-related disorders.
The good news is that lifestyle changes can help improve cardiometabolic health. Regular physical activity, a balanced diet, adequate and quality sleep, stress management and avoiding smoking are among the measures that can support overall health.
A new study published in Cell Reports Medicine has added to the growing evidence on the relationship between exercise intensity and cardiometabolic health.
Researchers found that high-intensity exercise, particularly sprint interval training, may improve several cardiometabolic health markers more effectively than moderate-intensity exercise, such as continuous cycling.
The findings suggest that incorporating short periods of vigorous activity into an exercise routine could provide meaningful health benefits. However, the appropriate intensity and type of exercise can vary depending on an individual’s fitness level and health status.
Overall, the research highlights the potential value of exercise intensity alongside regular physical activity as people seek to improve cardiovascular and metabolic health.
