A long list of cardiorespiratory fitness benefits from high intensity interval training

personal trainers at work personal training New Orleans

From the American Heart Association Scientific Statement, Importance of Assessing Cardiorespiratory Fitness in Clinical Practice: A Case for Fitness as a Clinical Vital Sign: A Scientific Statement From the American Heart Association | Circulation, an excerpt:

“Cardiorespiratory fitness is a potentially stronger predictor of mortality than established risk factors such as smoking, hypertension, high cholesterol, and type 2 diabetes mellitus.”

It is important to note that muscles stimulate the cardiovascular system to make positive changes, not the other way around. When the muscles are too weak to push the cardiovascular system, cardiorespiratory fitness declines. High intensity interval training (HIIT) increases strength and promotes cardiorespiratory fitness. The benefits:

Chocolate another charmed substance?

See video

The study: Heavy chocolate consumption may be linked to heart health  

The result: From an analysis of seven studies with 100,000 participants, five of the studies reported “a beneficial link between higher levels of chocolate consumption and the risk of cardiovascular events. They found that the ‘highest levels of chocolate consumption were associated with a 37% reductionin cardiovascular disease and a 29% reduction in stroke compared with lowest levels.’ No significant reduction was found in relation to heart failure.”

And this: 

“A number of recent studies have shown that eating chocolate has a positive influence on human health due to its antioxidant and anti-inflammatory properties. This includes reducing blood pressure and improving insulin sensitivity (a stage in the development of diabetes).”

High intensity strength training lowers blood pressure

personal trainers at work personal training New Orleans

To lower your blood pressure do high intensity training HIT or start strength training. Better yet, do them both at the same time.

High intensity training HIT consists of a series of short bouts of demanding exercise with rest or active recovery (less demanding exercise) in between each bout of exercise. HIT for strength can be done performing a series of strength training exercise with little rest in between. Evidence from two studies point to the positive effects both HIT and strength training have on lowering blood pressure.

This study, High-intensity interval training and hypertension: maximizing the benefits of exercise? compared continuous moderate-intensity exercise training (CMT) and high-intensity interval training (HIT), to determine which was better for lowering blood pressure.  They presented evidence that:

“HIT for several factors involved in the pathophysiology of hypertension raises the hypothesis that HIT may be more effective for preventing and controlling hypertension”.

From this article, Even Short Bursts Of Exercise Can Reverse Heart Problems In People With Type 2 Diabetes, come these quotes:

“In a new study published in Diabetologia, researchers examined the effect of brief, high-intensity workouts on type 2 diabetes patients who had already experienced heart abnormalities due to the disease. They found that these short bursts of exercise had a positive impact on the patients, improving their heart structure and offering some of the best protection for diabetes control.”

"The researchers measured cardiac structure and function with MRIs, and they found that these high-intensity, intermittent workouts greatly improved heart structure and function."

High intensity training better for coronary artery disease patients

personal trainers at work personal training New Orleans

Two groups of stable patients with coronary artery disease (CAD) regularly walked on treadmills three times a week for ten weeks. One group walked at high intensity (80-90% of VO2peak); the other groups walked at moderate intensity (50-60% of VO2peak)

The results from this study, High intensity aerobic interval exercise is superior to moderate intensity exercise for increasing aerobic capacity in patients with coronary artery disease were:

After training VO2peak increased by 17.9% (P=0.012) in the high intensity group and 7.9% (P=0.038) in the moderate intensity group. The training-induced adaptation was significantly higher in the high intensity group (P=0.011).

Their conclusion:

High intensity aerobic interval exercise is superior to moderate exercise for increasing VO2peak in stable CAD-patients.

Study: High Intensity training beneficial and safe for those with heart disease

personal trainers at work personal training New Orleans

New research examines the question of whether high-intensity exercise is beneficial for heart disease patients. The result:

“The four studies, which were composed of patients who either had acute coronary syndrome or angina pectoris, confirmed previous findings that high-intensity exercise is safe, even for patients with CHD” – quote is from this article High-Intensity Exercise for People With Heart Disease.

Another quote from the article:

"When we compared VO2max before and after the training period, we found that the number of training sessions, the subject's age or baseline fitness levels had no impact, but the intensity of the intervals had a significant effect, and seems to be the most important characteristic of an effective interval session.”

Getting to your target heart rate with resistance training

The client was 58 and very fit. She was wearing a pulse meter on her wrist. Ninety seconds into the workout her pulse was 148 which is approaching her maximum for a person her age.

One method of determining one’s maximum heart rate is to subtract one’s age from 220 bpm. Using this method this client’s maximum heart rate would be 162 bpm.

We began the workout with the leg press using a heavy weight and slow initial movements. The leg press involves large muscle groups and can get one’s heart rate up in short order. The slow starts minimize force associated with injury and allow one to warm up safely with the heavier weights. The warm up is in effect incorporated in to the first set using a challenging weight. After a minute she was breathing hard and I told her to move faster. At this point her muscles were warmed up and appreciably weaker. Warmed-up weaker muscles are unlikely to generate enough force to cause injury as long as good form is maintained. Her attempts to move fast did not amount to much at that point in the set, but it did allow her to keep moving and achieve a deeper fatigue.

The heart benefits of weight training

The results From this study Get Heart Healthy by Lifting Weights :

Resistance training is more beneficial than many believe," says lead researcher, Dr. Scott R. Collier. The resistance exercises produced a different pattern of blood vessel responses than the aerobic exercise, suggesting that the former may have important and unique benefits for cardiovascular health. The resistance exercise produced greater increases in blood flow to the limbs—even though it also caused small increases in central arterial stiffness. In contrast, aerobic exercise decreased arterial stiffness—but without an increase in blood flow.

Resistance exercise also led to a longer-lasting drop in blood pressure (as much as 20 percent) after exercise, compared to aerobic exercise.

Lowering metabolic syndrome risk factors, which type of exercise is most effective?

A study designed to test the efficacy of exercise in lowering metabolic risk factors consisted of three groups.  One group used a less-intense regimen called “moderate continuous-training” (CME). Another group did not exercise, and the third group used a high-intensity aerobic-interval training for four months.
From this article High-intensity exercise better at improving metabolic syndrome risk factors the results:

“• Short bursts of high-intensity exercise, rather than longer spells of moderate-intensity, exercise may improve the health of people with metabolic syndrome.

The Heart Can Benefit From Brief Intense Exercise

From this Science daily article Brief, Intense Exercise Can Benefit The Heart, Study Shows:

"More and more, professional organizations are recommending interval training during rehabilitation from diseases like chronic obstructive pulmonary disease, peripheral artery disease and cardiovascular disease. Our research certainly provides evidence that this type of exercise training is as effective as traditional moderate intensity training," says MacDonald. "We wouldn't be surprised to see more rehabilitation programs adopt this method of training since it is often better tolerated in diseased populations".
