Due to modern lifestyle, health and fitness are two things that are missing from most people’s lives. Our lives are driven by technology and tend to revolve around it. This is a bigger problem for children who are growing surrounded by mobiles and gadgets. 

The damage can be prevented by exercise. According to a new study published in the journal Pediatrics, vigorous exercise for 20 minutes daily works wonders for teens. The study said that exercising vigorously for 20 minutes may be the best way for teens to develop cardiorespiratory fitness. 


The study was conducted on 339 participants aged 13 and 14. The participants took part in school-based exercise programs particularly focused on running. The study participants performed exercises by wearing a wrist tracker to calculate the intensity of their workouts. They took part in the study for two years, as reported by the Washington Post. 

The researchers found that the teens maximized their cardiorespiratory fitness at 20 minutes of exercising vigorously. Exercising more than 20 minutes didn’t improve their cardiorespiratory fitness. But, the current guidelines suggest that young people should exercise for 60 minutes daily to maintain their cardiorespiratory fitness. 


Cardiorespiratory fitness means how efficiently the heart and lungs supply oxygen to the body’s other organs and muscles during physical exertion. Good cardiorespiratory fitness is inversely proportional to cardiovascular diseases, hypertension, diabetes, obesity, and poor mental health. 

As the current guidelines suggest that young people should exercise for at least 60 minutes a day, experts said that it is very difficult for most children to take time out of their busy schedules to exercise for long. Additionally, the Centers for Disease Control Prevention (CDC) data suggests that just one-fourth of American youths are physically active for one hour daily. 

The results from the latest study suggested that teens wouldn’t have to exercise for a longer period to get fit. Exercising vigorously for 20 minutes rather moderately, for instance, brisk walking for longer durations, would have better results in attaining cardiorespiratory fitness. 


Exercising for longer hours may have other benefits like muscle strengthening. More time under tension means more muscle development. Also, working out for longer durations can improve other physical fitness components like stamina, endurance, and agility. Yet, these are the personal goals of an individual. Vigorous exercise for short durations would be beneficial to keep a person fit. 

The researchers said that they only assessed cardiorespiratory fitness in the study. There may be other benefits of moderate or low-intensity exercises on the body. Also, the research didn’t include the amount or importance of rest in developing cardiorespiratory fitness. Rest, in general, is considered as significant as exercise.
