High-Intensity Interval Training (HIIT) has become a popular workout method for those looking to burn fat and build muscle quickly. This training involves short bursts of intense exercise followed by brief periods of rest or lower-intensity exercise. The benefits of HIIT are numerous, from improving cardiovascular health to boosting metabolism. Let’s explore how HIIT can help you achieve your fitness goals and provide some sample workouts to get you started.

Benefits of HIIT workouts

Burns fat efficiently

HIIT workouts are highly effective at burning calories and fat in a short amount of time.The intense bursts of activity increase your heart rate and metabolism, leading to greater calorie burn during and after your workout. This phenomenon, known as the “afterburn effect” or excess post-exercise oxygen consumption (EPOC), means you continue to burn calories even after you’ve finished exercising.

Builds muscle

The varied exercises in HIIT can target different muscle groups, promoting muscle growth and strength. Combining resistance training with high-intensity cardio helps to build lean muscle mass while simultaneously reducing fat. This makes HIIT an excellent choice for those looking to tone their bodies and increase muscle definition.

Improves cardiovascular health

HIIT improves cardiovascular health by increasing your heart rate and enhancing blood flow. This type of training strengthens the heart, improves circulation, and can reduce blood pressure. Regular HIIT sessions can lead to better endurance and overall cardiovascular fitness.

Saves time

One of the major advantages of HIIT is that it’s time-efficient. You can get a full workout in as little as 20-30 minutes, making it ideal for those with busy schedules. The intensity of the workouts ensures that you’re maximising your effort in a short period.

Increases metabolic rate

HIIT has been shown to boost metabolic rate, helping you burn more calories throughout the day. This increased metabolism can contribute to weight loss and improved energy levels.

Can be done anywhere

HIIT workouts can be performed with minimal equipment, making them accessible for people who prefer to exercise at home or while travelling. Bodyweight exercises like squats, push-ups, and burpees are commonly used in HIIT routines and require no special equipment.

Sample HIIT workouts

HIIT workouts offer a fast and effective way to burn fat, build muscle, and improve overall fitness. With the ability to customise the intensity and duration, HIIT can be adapted to any fitness level. The key is to push yourself during the high-intensity intervals and give your body time to recover during the rest periods. By incorporating HIIT into your fitness routine, you can achieve significant results in a short amount of time, making it a valuable addition to any exercise regimen.

Exercise Boosts Brain ‘Ripples’ Tied to Learning and Memory

Exercise Boosts Brain ‘Ripples’ Tied to Learning and Memory

Each time you go for a jog, ride your bike, or get active in other ways, you’re giving your brain a boost. A small new study has for the first time directly documented this phenomenon, which the researchers call “ripples” — brief bursts of electrical activity in a part of the brain called the hippocampus.

While exercise is known to improve memory, scientists have mostly studied this effect by using behavioral tests or brain imaging methods like MRIs, says Michelle Voss, PhD, one of the study’s authors, a professor, and the director of the Health, Brain, and Cognitive Lab at the University of Iowa in Iowa City.

But she says these approaches can’t precisely identify where “ripples” originate, particularly in the deep brain structures like the hippocampus, a part of the brain strongly connected to memory and learning, she says.

The current study, published in Brain Communications, recorded electrical activity directly, using surgically implanted (intracranial) electrodes. “This allowed us to observe how exercise changes the brain’s memory circuits in real time,” Dr. Voss says.

20-Minute Bursts of Exercise Increase Brain Ripples

To conduct the study, the researchers recruited 14 participants between ages 17 and 50 with drug-resistant epilepsy. The subjects had already been fitted with intracranial electrodes as part of their preparation for surgical epilepsy treatment.

The participants performed a 5-minute warm-up and then rode a stationary bike for 20 minutes at a pace they could maintain. Researchers recorded their brain activity before and after the biking session.

The electrodes showed an increased rate of so-called sharp-wave ripples from the hippocampus and connections with cortical regions of the brain, which are involved in learning and memory.

“Sharp-wave ripples have long been known from animal studies to play a central role in memory,” Voss says, adding that recent studies using intracranial recordings in humans also support the importance of ripples for human memory.

“Our findings are the first to show that exercise can modulate these ripple signals in the human brain,” she says.

Researchers also observed that larger increases in heart rate during exercise were associated with larger changes in ripple activity in cortical networks, Voss adds.

What’s Already Known About Exercise, Memory, and Learning

“We know that exercise is the number-one thing we can do to enhance our memory and learning,” says Catherine Franssen, PhD, an assistant professor in the School of Life Sciences and Sustainability at Virginia Commonwealth University in Richmond. “Exercise will enhance both our ability to learn new things and our ability to remember previously learned things.”

Movement helps pump oxygenated, nutrient-rich blood to the brain, says Dr. Franssen, who was not involved with the new study: “We’re able to activate those brain cells more effectively and energize them.”

The increased blood flow stimulates the growth of new neurons and enhances the production of brain-derived neurotrophic factor (BDNF), a molecule that strengthens connections between brain cells and supports learning, says the neurologist David Perlmutter, MD, who was not involved with the latest study.

Exercise helps build connections between neurons, which deepens and strengthens brain networks, Franssen says.

Physical activity also improves metabolism, which improves insulin sensitivity, helping blood sugar regulation and giving the brain a “more stable and reliable supply of fuel,” Dr. Perlmutter says.

“This is critically important because the brain is an energy-intensive organ, consuming roughly 20 percent of the body’s energy despite representing only a small fraction of body weight,” he adds.

The Research Has Limitations

Voss says researchers were careful to “exclude signals that contained epileptic activity. However, of course, we can’t statistically control for the accumulated effects of having epilepsy on the brain.”

The exercise-brain ripple patterns observed in the current study also closely match those observed in healthy adults using noninvasive brain imaging, such as MRI, she added.

“That convergence across very different methods is one of the strongest indicators that the effects are not specific to epilepsy, but reflect a more general human brain response to exercise,” Voss said.

Researchers also didn’t directly test memory performance, Voss notes. “While hippocampal ripples are strongly linked to memory processing in decades of neuroscience research, the next step will be to measure how exercise-related changes in ripples relate to memory performance in the same individuals.”

Future studies should also compare exercise with other everyday activities, such as sitting quietly or light movement, to determine how specific these effects are to aerobic exercise at the intensity that was studied, she says.

Satisfy Your Brain’s Exercise Craving

It’s never too early or too late to start exercising for brain health, Franssen says.

People of any age, from grade-school children to people in their nineties, can benefit from increased physical activity, Perlmutter says. “My recommendation is to consider taking advantage of the connection between physical activity and brain health across the entire range of human aging.”

Any type of exercise is great, Franssen says, but especially “repetitive behaviors,” like swimming, jogging, and walking.

“Sometimes we let the hugeness of putting in a huge fitness routine get in our way,” she says. “Having a little exercise snack every so often is also very important to improving cognition.”

Higher Fitness Levels Amplify Brain Benefits After Exercise, Study Finds

Higher Fitness Levels Amplify Brain Benefits After Exercise, Study Finds

Increasing our level of physical fitness leads to a bigger release of brain-boosting proteins following one session of exercise, a new study led by a UCL researcher has found.

The study, published in Brain Research, took a group of inactive unfit participants through a 12-week training programme of cycling three times per week and made them fitter. Researchers found as their fitness increased, so did the amount of brain-derived neurotrophic factor (BDNF) released following exercise, resulting in improved brain function.

Just 15 minutes of moderate to vigorous aerobic exercise releases BDNF, a brain protein which is known to support the formation of new neurons and new synapses (connections between brain cells), and maintains the health of existing neurons. This is the first study to show that for unfit people, just 12 weeks of consistent training can boost the brain’s response to a single 15-minute workout.

The study, led by Dr Flaminia Ronca (UCL Surgery & Interventional Science, and the Institute of Sport, Exercise and Health), involved 30 participants – 23 male and seven female – taking part in the 12-week programme. To assess fitness levels throughout the programme, participants completed VO2max tests every six weeks, which measures the maximum rate of oxygen your body can consume and use during intense exercise.

BDNF levels were measured pre- and post-VO2max testing, alongside a series of cognitive and memory tests, while also measuring changes in brain activity in the prefrontal cortex – where executive functions such as decision-making, emotion regulation, attention and impulsivity are controlled.

By the final week of the trial, results showed that baseline levels of BDNF did not change, but participants did show a larger spike of BDNF following intense exercise, compared to how their brains responded to intense exercise before the 12-week programme. This was linked to improvements in VO2max (aerobic fitness).

Higher overall BDNF levels and stronger exercise-induced increases were also associated with changes in activity across key areas of the prefrontal cortex during attention and inhibition tasks, though not during memory tasks.

Overall, the results showed that increasing physical fitness can enhance the brain’s ability to produce BDNF in response to acute bouts of exercise, which can have a strong positive influence on neural activity.

Lead author Dr Flaminia Ronca said: “We’ve known for a while that exercise is good for our brain, but the mechanisms through which this occurs are still being disentangled. The most exciting finding from our study is that if we become fitter, our brains benefit even more from a single session of exercise, and this can change in only six weeks.”
