Pedometers can effectively measure health and fitness

A basic pedometer can prove suffice for measuring health-promoting physical activity, according to a study comparing pedometers with more complex devices. Simply counting steps captured a remarkable amount of information about the participants’ aerobic fitness and cardiovascular health.

The general recommendation for physical activity is to be active at least at a moderate intensity for at least two-and-a-half hours a week. The greatest health gains are made by progressing from a completely sedentary lifestyle to some level of activity.

However, monitoring activity levels and health outcomes is challenging, for individuals and healthcare professionals alike. This study investigated how well pedometers match the more advanced and established measurements provided by accelerometers.

While a pedometer only counts steps, an accelerometer provides information on the total volume of physical activity, including the number of steps, as well as detailed information about the activity, such as movement patterns, time of day, intensity level, and more.

Step data as a basis

The study encompassed 4,127 people, aged 50-64 years, whose aerobic fitness was estimated with the aid of a cycle ergometer. Their health was measured using a combination of waist circumference, blood pressure, blood lipids, and insulin sensitivity.

The participants were provided with accelerometers for a week so that researchers could collect step data together with more advanced data. When the step data were compared with the complete accelerometer data, the step count was found to have captured a full 88 percent of the health information provided by the accelerometer measurements.

According to the researchers, the results demonstrate the reliability of step counting as a method for measuring health outcomes when linked to individual aerobic fitness and cardiovascular disease risk factors, thereby by validating the use of step counting as opposed to accelerometer measurements.

One of the lead researchers behind the study is Jonatan Fridolfsson, physiotherapist and researcher at the Centre for Lifestyle Intervention at the University of Gothenburg and Sahlgrenska University Hospital.

The study supports the use of step counting, which is available to most people via their cellphone or activity tracker, as a practical and viable metric for assessing physical activity in relation to health. This can make it easier for both individuals and healthcare professionals to understand, measure, and improve activity levels in everyday life.”

Fast pace is beneficial

The study also shows that cardiovascular health optimization requires brisk walking at a minimum. Walking at a normal pace did not produce the same health benefits in the study group, which was comprised of middle-aged individuals with no underlying heart disease.

“This suggests that we need greater emphasis on physical activity of sufficient intensity in public health recommendations,” says Jonatan Fridolfsson.

Another finding concerned cadence when walking, with 100 steps per minute often considered the lower threshold for sufficient intensity. However, among the participants in this study, a minimum cadence of 80 steps per minute was most strongly associated with good aerobic fitness and cardiovascular health.

“The point is that it’s important to adapt the idea of sufficient intensity to the individual. For this particular group, and their daily physical activity, a threshold of 80 steps per minute was more strongly associated with aerobic fitness and cardiovascular health markers.”

The study was conducted at the Centre for Lifestyle Intervention at the University of Gothenburg and Sahlgrenska University Hospital in collaboration with the Center for Health and Performance (CHP) at the University of Gothenburg.

The results are published in the Journal of Internal Medicine and are based on data from the SCAPIS population study, the largest in Sweden in the field of heart, vascular, and lung disease, encompassing 30,000 randomly selected Swedes aged 50-64 years who underwent comprehensive health exams.

Exercise scientist reveals the strength training mistake many women make, even after lifting for years

Wondering how much weight you should be lifting in the gym to build strength? Dr Stacy Sims says that not going heavy enough could be the biggest mistake women are making in their workouts.

What strength training looks like might differ (for example, some prefer callisthenics over classic weight training) for some, but one thing is clear – it needs to be a challenge.

Jogging 101: Benefits for Your Body and Mind

Walking and running share a number of benefits — but what about that sweet middle ground between the two?

“Jogging is about creating a steady pace,” says sports and exercise medicine specialist Leonardo Oliveira, MD. “Instead of focusing on speed, you’re focused more on endurance with good, quality steps.”

Before your next jaunt, Dr. Oliveira shares the many benefits of jogging and how it can help improve your overall health and wellness.

9 benefits of jogging

Unlike running, where you’re focused on targeting different heart rate zones, jogging involves keeping a more stable and persistent pace. If you’re jogging at a moderate intensity, for example, your target heart rate will usually fall into zone 2, at 60% to 70% of your max heart rate.

“When you’re jogging, you should be able to carry on a conversation as you breathe through your nose,” says Dr. Oliveira. “If you’re doing just 15 minutes of jogging three times a week, you’re already going to notice the benefits.”

Here’s how you can benefit from jogging.

1. Reduces stress

Jogging, like other exercises, can help decrease your stress levels. As an aerobic exercise, it helps release endorphins, which can boost your mood and create feelings of euphoria or satisfaction. Not only does it provide an outlet for pent-up energy, but jogging outside also allows you to spend more time in nature, which provides even more mental health benefits.

“Research shows exercise can be as effective as medication when treating depression because of its wide-ranging benefits,” says Dr. Oliveira.

2. Burns calories

Jogging is a full-body exercise that offers a higher calorie burn than some other aerobic exercises. According to the widely used Compendium of Physical Activities, jogging burns about 7.5 calories per kilogram of body weight each hour. That means you can burn about:

  • 8 times as many calories as sitting quietly
  • 4 times as many calories as walking
  • 2.6 times as many calories as stationary cycling

“Jogging will burn more calories in a shorter period of time than cycling, especially if you’re not used to exercising,” reports Dr. Oliveira.

3. Improves insulin resistance and boosts metabolism

Insulin resistance is one of the biggest barriers to having a healthy metabolism. Insulin helps your body break down glucose for energy. But if your body can’t do that, your metabolism slows down, leading to:

  • Lower energy levels
  • Weight gain
  • An inability to burn fat

“Exercising at higher intensities helps increase metabolism and insulin resistance,” says Dr. Oliveira. “But researchers have also found that even lower-intensity exercises, like jogging, for longer periods of time can have the same effect.”

4. Strengthens your heart

Jogging also has positive impacts on your heart and its ability to pump blood to the rest of your body. That’s because it contributes to hypertrophy, or the strengthening of your heart’s muscle tissues.

“As you develop endurance, the amount of blood in one pump increases,” explains Dr. Oliveira. “When your heart gets stronger, it contracts more efficiently, which decreases your resting heart rate.”

5. Improves lung expansion and gas exchange

The more you work on building endurance and stamina, the more likely it is that you’ll improve your overall ability to breathe — both at rest and while jogging.

“Consistent aerobic exercise helps your lungs get stronger and more efficient,” says Dr. Oliveira. “Over time, you won’t need to breathe as often because each breath brings in more oxygen than before.”

6. Activates muscles

Jogging activates major muscle groups, including your:

  • Quads
  • Hamstrings
  • Glutes
  • Core
  • Back

“Strength training is a good complement to jogging because it can help strengthen all the areas of your body,” says Dr. Oliveira. “This can help you handle longer distances.”

7. Reduces stiffness

“Jogging is one of those activities where once you get going, you start to feel better,” notes Dr. Oliveira. “It’s an exercise that helps warm up your muscles and lubricate your joints, which can help with the overall sense of stiffness that comes with age.”

That said, jogging is still a high-impact exercise because it forces you to bear down weight as your feet hit the pavement. Consider working with a physical therapist or athletic trainer to reduce the risk of further injury if you:

  • Have arthritis
  • Have an active injury
  • Had previous sprains or fractures in your lower body

8. Improves endurance

“The more you jog, the more you’ll increase your functional aerobic capacity,” says Dr. Oliveira. “Someone who jogs regularly will have better physical fitness that will help them last longer on a bike or a walk than someone who’s just getting started.”

Your ability to breathe and move also extends to other daily activities that demand cardiovascular strength and endurance, like climbing stairs.

9. Provides better quality of life and other mental health benefits

Research shows that any amount of jogging — even just once a week — can improve your quality of life and lower your risk of dying from cancer and cardiovascular-related issues.

“Jogging is a great form of exercise, but it’s not the only one,” notes Dr. Oliveira. “The most important thing is to work on being healthy and strong. And for a lot of people, if you’re looking to advance your physical fitness, jogging is a good place to start.”

Michelle Yeoh, 63, uses ‘exercise snacking’ to stay fit – here’s why mini workouts have big benefits

Michelle Yeoh, 63, uses ‘exercise snacking’ to stay fit – here’s why mini workouts have big benefits

As an increasing number of scientific studies are published citing the benefits of ‘exercise snacking’ – short bouts of physical activity sprinkled throughout the day – one celeb has sworn by the practise for several years already. The woman in question? Acting great Michelle Yeoh. Below, we look at the power of mini workouts and why the Oscar-winner’s go-to move is so effective.

Stretching

Michelle revealed to Vogue that she incorporates fitness into her morning routine in a way that’s incredibly time-efficient. ‘Remember, you can do your kicks, you can do your stretches, while you are also waking up,’ she said. Indeed, research has shown that regular stretching can improve flexibility, reduce muscle stiffness and improve blood circulation – all crucial elements of healthy ageing.

And you don’t have to stretch for very long, either. One study found that while static stretching improves flexibility in adults, there was no additional benefit observed beyond four minutes per session or 10 minutes per week. So, it seems that a short stretching sesh (you don’t even have to get out of bed to do it) like Michelle’s is a very worthwhile habit to adopt.

Squats

In her Vogue interview, Michelle also shared that she performs squats most days while doing her skincare routine. Virtually every expert and trainer we speak to here at Women’s Health lists squats as one of the most important moves for women to do as they age. A compound exercise (when multiple muscle groups are used), squats also mirror the vital movement pattern of sitting down and getting back up again.

Numerous studies have highlighted the benefits of this simple exercise for posture, strength and power, and one paper even found that intermittent squat exercises performed during prolonged periods of sitting may boost brain power. Whether you’re squatting mid-moisturise like Michelle or while you’re waiting for the kettle to boil, the science suggests sprinkling squats into your day can be really quite powerful.

The power of habit stacking

As Michelle’s routine shows, adopting a sustainable exercise routine often relies on habit stacking – adding a movement to something you already do every day, like doing your skincare or brushing your teeth.

BRB, we’re just off to do our daily squats.
