Improves Oxygen Consumption
Your muscles need oxygen to work, and the better their ability to use that oxygen the better they work. Consuming more oxygen makes muscles more efficient, and allows for increased endurance and speed. HIIT exercises are shown to be just as effective at improving oxygen consumption as endurance training such as cycling or running, but takes half the time.
Improves Blood Pressure
HIIT can have an incredible effect on overweight or obese people with hypertension. There’s been extensive research into the effect of HIIT exercises on heart rate and blood pressure, and they all say the same thing – that HIIT can reduce blood pressure and eliminate tachycardia. The effects can even be more substantial than frequent moderate-intensity exercise, the recommended way to reduce blood pressure and improve heart health.
Reduce Blood Sugar
HIIT increases insulin sensitivity as part of the after-burn effect it has on your body. When insulin sensitivity is high, a lower amount is needed to break down the glucose in your blood so your insulin becomes more efficient. This is great news for anyone suffering from hyperglycemia, as HIIT programs will reduce your blood sugar and reduce your risk of type 2 diabetes.
Lose Weight Not Muscle
Many cardio exercises designed to improve cardiovascular output and burn calories can contribute to the loss of muscle mass in certain areas. This doesn’t happen with high-intensity interval workouts as many of the exercises use your own bodyweight for resistance, helping you to maintain and strengthen muscles instead of losing them.
So, HIIT can not only burn calories more efficiently than other exercises it can also improve your blood sugar, muscle mass, muscle efficiency and can even lower your blood pressure, making it the perfect exercise for just about anyone.
