IF YOU ever wanted an excuse to skip out on your Bootcamp or personal training session, this could be it. Two new studies suggest too much high-intensity exercise could lead to heart problems. The first study, conducted by German researchers, followed more than 1000 people mostly in their 60s, who had existing heart disease and had enrolled in an exercise program to prevent further heart health issues.
As hypothesised, the least physically active people were at increased risk for heart problems and earlier death. But the most active group, those who did daily strenuous physical activity, also had increased risk of dying of heart problems than people who were active only two to four times a week, according to the study.
In the second study, Swedish researchers surveyed more than 44,000 men between the ages of 45 and 79 about their physical activity habits at various ages throughout their lives. Researchers also monitored the heart health of the men for an average of 12 years, looking in particular for atrial fibrillation, a type of irregular heartbeat ....................................................................
Gotta admit I was addicted to interval training and hill sprints for many years and while never being fitter, I always wondered if it was a bit risky when taken to far. I guess that's the key, moderation.
but you hear Doctors complain that people who just lift have strong muscles but weak hearts. HIIT is somewhat a diluted version of resistance training. I wonder if its the prolonged nature of HIIT that may be the risk.
"In the second study, Swedish researchers surveyed more than 44,000 men between the ages of 45 and 79 about their physical activity habits at various ages throughout their lives ........... The most active men — those who completed intense exercise for more than five hours a week — were 19 per cent likelier to have developed an irregular heartbeat by age 60"
One bloke I use to follow on elite fts had a theory that cardiac strength was built on cardio in the 120-130 BPM range. Not with high intensity intervals.
yep, that Welsh dude was an Ironman whose heart is stuffed now. Sure there might be others.
The article did say though "people who had done 5 hours per week of high intensity training at various stages of their lives". Who does 5 hours of HIIT per week? Pretty excessive!
