mau awet muda? lakukan olahraga ini setiap hari

Jakarta, Jenis olahraga apapun sebenarnya punya manfaat bagi kesehatan, selama dilakukan secara rutin dan terukur. Namun dalam kaitannya dengan proses penuaan, jenis olahraga tertentu punya manfaat lebih dibanding yang lain.

High Intensity Interval Training (HIIT) atau latihan interval dengan intensitas tinggi, dalam sebuah penelitian terbaru diklaim paling ampuh memperlambat proses penuaan. Penelitian tersebut dimuat di jurnal Cell Metabolism.

Dalam penelitian tersebut, HIIT terbukti meningkatkan kemampuan mitokondria untuk menghasilkan energi 69 persen lebih banyak pada partisipan lanjut usia. Sedangkan pada partisipan muda, latihan ini meningkatkan produksi energi pada mitokondria hingga 49 persen lebih banyak.

Mitokondria merupakan bagian sel yang menyuplai energi untuk beraktivitas. Normalnya, aktivitas mitokondria akan berkurang seiring bertambahnya usia seseorang.

Selain menemukan peningkatan metabolisme energi dalam mitokondria, para ilmuwan juga mendapati peningkatan fungsi paru-paru pada partisipan yang melakukan HIIT. Misalnya pada kelompok partisipan berusia muda, jumlah oksigen yang bisa ditampung meningkat hingga 28 persen.

Idealnya, olahraga yang bervariasi lebih dianjurkan jika tujuannya adalah untuk menjaga kebugaran. Ini diakui juga oleh sang peneliti, Dr Sreekumaran Nair dari Mayo Clinic di Rochester.

“Jika harus memilih satu olahraga, saya menganjurkan high intensity interval training, tapi saya pikir akan lebih bermanfaat kalau mereka melakukan HIIT 3-4 kali dan diselingi strength training (latihan otot),” katanya, dikutip dari Newscientist.

 

High-intensity interval training (HIIT), also called high-intensity intermittent exercise (HIIE) or sprint interval training (SIT), is a form of interval training, a cardiovascular exercise strategy alternating short periods of intense anaerobic exercise with less intense recovery periods. HIIT is the concept where one performs a short burst of high-intensity (or max-intensity) exercise followed by a brief low-intensity activity, repeatedly, until too exhausted to continue. Though there is no universal HIIT session duration, these intense workouts typically last under 30 minutes, with times varying based on a participant’s current fitness level.

It’s Efficient

Super-efficient HIIT is the ideal workout for a busy schedule—whether you want to squeeze in a workout during your lunch break or to get in shape for a fast-approaching event. Research shows you can achieve more progress in a mere 15 minutes of interval training (done three times a week) than the girl jogging on the treadmill for an hour. (Watch and try this video of a 10-minute fat-blasting cardio routine that burns more calories than a half hour on the treadmill!) And according to a 2011 study presented at the American College of Sports Medicine Annual Meeting, just 2 weeks of high-intensity intervals improves your aerobic capacity as much as 6 to 8 weeks of endurance training.

That’s not even the best part! Using the Tabata training method, you can complete an effective HIIT workout in just 4 minutes.

You’ll Burn More Fat

Not only do you burn more calories during a HIIT workout, but the effect of all that intense exertion kicks your body’s repair cycle into hyperdrive. That means you burn more fat and calories in the 24 hours after a HIIT workout than you do after, say, a steady-pace run.

You’ll Build a Healthier Heart

Most people aren’t used to pushing into the anaerobic zone (that lovely place where you can’t breathe and you feel like your heart is trying to jump out of your chest). But in this case, extreme training produces extreme results. One 2006 study found that after 8 weeks of doing HIIT workouts, subjects could bicycle twice as long as they could before the study, while maintaining the same pace.

There’s No Equipment Necessary

Running, biking, jump roping, and rowing all work great for HIIT, but you don’t need any equipment to get it done. High knees, fast feet, or anything plyometric like jumping lunges work just as well to get your heart rate up fast. In fact, some equipment like dumbbells can make HIIT less effective because you want the focus to be on pushing your heart to its max, not your biceps.

You Lose Weight, Not Muscle

Anyone who has been on a diet knows that it’s hard to not lose muscle mass along with fat. While steady state cardio seems to encourage muscle loss, studies show that both weight training and HIIT workouts allow dieters to preserve their hard-earned muscles while ensuring most of the weight lost comes from fat stores. Win/win!

You’ll Increase Your Metabolism

In addition to increased fat burning and more muscle preserved, HIIT stimulates production of your human growth hormone (HGH) by up to 450 percent during the 24 hours after you finish your workout. This is great news since HGH is not only responsible for increased caloric burn but also slows down the aging process, making you younger both inside and out!

You Can Do It Anywhere

You can do it in a boat, you can do it with a goat. You can do it here or there, you can do it anywhere! Dr. Seuss would have loved HIIT. Since it’s such a simple concept—go at maximum effort for a short period of time followed by a recovery period and repeat—you can adapt it to whatever time and space constraints you have.

It’s Seriously Challenging

This is not a workout you can do while reading a magazine or chatting with your friend. Because it’s so short, you will be working hard the whole time. The trade-off is this format offers seasoned exercisers a new challenge and new exercisers a quick way to see results. You may be in pain, you may be sucking wind, but you definitely won’t be bored!
