I used to swear by high-intensity cardio workouts to keep me fit. As part of my CrossFit style training regime, I\u2019d do at least three 10- to 20-minute HIIT workouts per week that would leave me breathless, sweaty and with my heart rate in zones four (80%-90% of my maximum heart rate) and five (90%-100%).<\/p>\n

However, I was becoming bored with this style of training and I was beginning not to enjoy HIIT style workouts anymore.<\/p>\n

So, around six months ago, I decided to focus on strength training, coupled with playing tennis for an hour two every week<\/a>. Tennis raises my heart rate, but not as much as HIIT workout.<\/p>\n

So, is one to two hours of medium-intensity exercise enough, or is high-intensity training essential? I decided to find out.<\/p>\n

What are the benefits of medium-intensity exercise?<\/p>\n

Training in zone three, which is around 70 to 80% of your maximum heart rate, has specific benefits compared with high-intensity training, according to Alan Ruddock, associate professor of sport physiology and performance at Sheffield Hallam University.<\/p>\n

\u201cElite endurance athletes will utilise this medium intensity work within their training programme because what they have to do is balance intensity and volume,\u201d says Ruddock. \u201cThey\u2019ll do quite a lot of low-intensity work, but they also need to push the boundaries [with high-intensity work].\u201d<\/p>\n

\u201cMedium-intensity training blends mechanical demand, physiological stimulus, plus all of the psychological benefits,\u201d says Ruddock. In other words, it\u2019s good for your muscles and joints, your fitness levels and your mental health.<\/p>\n

Crucially, medium-intensity exercise can be fun, compared with high-intensity exercise. \u201cThe scientific literature tends to suggest that this medium-intensity cardio […] is actually the most enjoyable,\u201d says Ruddock.<\/p>\n

I can certainly vouch for this from my personal experience. High-intensity workouts were gruelling, and I often had to push myself through them despite my brain telling me to stop. During medium-intensity exercise, like tennis, the fatigue I feel is generally manageable, so I enjoy it a lot more.<\/p>\n

What are the benefits of high-intensity exercise?<\/p>\n

Although it might not always feel enjoyable, Ruddock says there are plenty of benefits to high-intensity cardio.<\/p>\n

\u201cThe aim with HIIT is to spend a considerable amount of time above 90% of your maximum heart rate,\u201d says Ruddock. \u201cThis helps us deliver more oxygen-rich blood to the body.\u201d<\/p>\n

High-intensity exercise can not only improve your cardio fitness, but have a positive affect on your immune and hormone health, and cognitive function.<\/p>\n

High-intensity exercise might also be the quickest way to get fitter. \u201cWe most quickly see adaptations [in the body] with sprint interval sessions,\u201d says Ruddock. \u201cStudies have shown that just six to nine sessions of sprint training can create rapid adaptations of endurance capabilities.\u201d<\/p>\n

This is much quicker than medium-intensity exercise, which takes between six to 12 weeks to affect the body.<\/p>\n

A 2008 study<\/a> published in Medicine & Science in Sports & Exercise looked at the effects on VO2 max of different types of training. VO2 max is the maximum volume of oxygen the body is able to use during exercise and is a good indicator of fitness levels.<\/p>\n

The study found that six weeks of zone three training improved participants\u2019 VO2 max by 14.3%, whereas six weeks of zone five training improved participants\u2019 VO2 max by 20.6%, showing how much quicker this style of exercise can improve your fitness.<\/p>\n

My experience swapping HIIT for medium-intensity cardio<\/p>\n

\n

\u201cI can exercise for longer, but just not as hard\u201d<\/p>\n<\/blockquote>\n

There are a few changes I\u2019ve noticed since replacing HIIT with tennis. For one, because I enjoy tennis, I choose to play it more regularly and do it for longer, and that\u2019s helped boost my endurance.<\/p>\n

After a few months, I needed fewer breaks, I wasn\u2019t as breathless and I could also play for longer. I also noticed running and cycling feel easier.<\/p>\n

Saying that, I\u2019ve lost some of my ability to sustain hard efforts. I notice that when I do push my body to its limits\u2014challenging myself with lots of burpees or sprinting on a SkiErg machine\u2014it feels more difficult.<\/p>\n

I can exercise for longer, but just not as hard.<\/p>\n

And even though I feel great after playing tennis, I don’t necessarily get the same level of endorphins as after a demanding HIIT class.<\/p>\n

Is medium-intensity exercise better than high-intensity exercise?<\/p>\n

According to Ruddock, high-intensity exercise isn\u2019t necessarily better than medium-intensity cardio, or vice versa. Variety matters.<\/p>\n

\u201cIt\u2019s a good idea to do both styles of exercise because you get training variation,\u201d says Ruddock. \u201cYou don\u2019t want to do one thing all the time, because it\u2019s not going to provide you with physiological benefits that are afforded to versatility.<\/p>\n

\u201cVariation in training load is almost as important as having a good structure in place. I would suggest that the average person combines as many different intensities as possible.\u201d<\/p>\n

That might feel overwhelming, but you don\u2019t need to cram all three into a week, especially if you\u2019re just beginning to return to exercise.<\/p>\n

I plan to add some short bursts of high-intensity exercise back into my routine, but I\u2019ll be pleased if I can convince myself to do a HIIT workout twice a month, increasing the frequency of those workouts over time. After all, doing something consistently is a smarter approach than trying to overload myself with exercise promises I just can\u2019t keep.<\/p>\n","protected":false},"excerpt":{"rendered":"I used to swear by high-intensity cardio workouts to keep me fit.
