How should you breathe when running?

runner face breathing

Breathing is the process of taking oxygen to fuel your running. You should not feel breathless while running.
The best way to breathe when running is to inhale and exhale using both your nose and mouth. Breathing through both your nose and mouth will keep your breathing steady while engaging your diaphragm for maximum oxygen intake.

Your breathing should be diaphragmatic which means your inhaling and exhaling should be deep enough to extend up to your stomach. Deep mouth breathing while running brings in more oxygen.

However, do not breathe forcefully through your nostrils as it can tighten your facial and jaw muscles which is not good when running. On the other hand, mouth breathing relaxes your jaw muscles.

If you feel breathless while running, it means you do not get adequate oxygen to fuel your workout. Then it is time to change the way you breathe.

What happens to your body after a long run?

Your ability to breathe (ventilatory capacity) will improve as you work out your respiratory muscles. Your body will be able to use oxygen efficiently to burn fat and glucose.

During running the energy is supplied by breaking down of glycogen stored in your muscles. Gradually the glycogen levels will be depleted which needs replenishing later.

Your heart will become stronger and your blood circulation will improve.

With time, the number and size of mitochondria (power houses of your cells) increase, improving your muscle endurance. This will be supported by improved circulation to your muscles, as capillaries which deliver blood to your muscles also enlarge and grow.

After a long run, you should hydrate yourself as soon as possible. Stretch major muscle groups, especially if they feel sore or tight. Using ice packs helps to soothe the sore muscles. You can consume a small nutritious meal afterwards.

How long does it take to see the results of running?

  • Your mood will elevate and you will be mentally relaxed once you start running. You may feel more confident and productive in life within days of starting to run.
  • You should see noticeable improvements in about 4-6 weeks, especially if you are new to running. If you can gradually increase your pace without getting breathless, it means that you are improving.
  • If your main aim is to get a toned and shapely body, combine your running with weight training and core-specific exercises to see better results.
  • If your main aim is to lose weight, it is important to stick to a proper diet plan which gives you a calorie deficit, if not only running won’t get you very far. If you make an effort to control your calorie intake along with running daily, then it is possible to see outstanding results within 2 – 3 months.
  • It will take at least 6 months of regular running to become heart healthy and to maintain your blood pressure and blood sugar levels.
  • A year of regular running will make you stronger and look good.
  • Years of regular running will make you look younger and aging will be slower.

How do you get a runner’s body?

Runner’s body is not only becoming skinny by losing fat. Gaining muscle mass in addition to that lean look along with a strong body is what most runners dream of. The ultimate goal is to achieve that runner’s body and improve performance.

Here are a few tips…..

  • Consult an expert – A sports nutritionist will help you to formulate a specific diet plan to suit your needs. It is up to you to stick to that plan to maintain a calorie deficit in order to lose weight by running.
  • Eat frequent small meals – Research has found that people who eat 6 small meals instead of 3 large meals have a lower body mass index (BMI). Frequent small but nutritious meals will keep your metabolism steady throughout the day, as well as fueling your workouts adequately. You should consume adequate protein to build muscle, along with fiber rich vegetables and fruits to ensure satiety.
  • Strength training – For a regular runner, adding regular strength training will help you reach that ideal weight and shape. Resistance training not only builds lean muscle, but also increases usage of fuel more efficiently during races and workouts. Your fitness will gradually improve too.
  • High intensity interval training – In a Canadian research, runners who did 4 -6 thirty second treadmill sprints 3 times per week lost more fat after 6 weeks when compared to runners who did 30-60 minutes of steady state aerobic training.
    Therefore, while you run regularly as steady state aerobic training, adding 1 -2 high intensity sessions each week will help you achieve a leaner physique.
