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.

How to avoid exercise burnout and still build muscle, according to an expert

How to avoid exercise burnout and still build muscle, according to an expert

Many of us have experienced the overwhelming feeling of mental and physical exhaustion that comes with exercise burnout. When you push yourself too hard without sufficient rest and recovery, it ultimately becomes counterproductive to your fitness goals, and your energy will tank along with your motivation. Not only that, your performance will suffer when you overtrain and under-recover, and you’re left sinking further into the couch, wondering how you’ll lift that next weight, swim that next lap, or run that next mile.

With a combo of the right nutrition, rest, recovery, and lowering your training intensity, you can get back on track. To learn more about avoiding burnout and torching fat while sculpting muscle for men, I asked certified personal trainer and Vice President of Education for Body Fit Training, Steve Stonehouse, to share some of his vast knowledge on the subject. With decades of experience in fitness education, fitness programming, and personal training, Steve Stonehouse developed an in-depth knowledge of weight loss, improving body fat composition, building muscle, and the best exercise plans that generate serious results. 

Expert advice on burning fat

The Manual: As the Vice President of Education for Body Fit Training, what are your top tips for burning fat and improving body composition for men? 

Steve Stonehouse: As the programmer and head of education, this is a little cliché, but I go for balance. Not every workout can be this CrossFit type, give it all you’ve got, smoke yourself, and work out — that’s not sustainable. The other end of the spectrum is just walking at a moderate pace for 20 minutes on a treadmill three times a week, because that’s not going to do it either. There’s value in both of those scenarios. 

It’s best to have a session or two each week where the intensity is very high, and you’re testing yourself and pushing yourself closer to your limits. That’s anaerobic exercise, which is 90% intensity or above. It’s fine, safe, and healthy to get there occasionally, but every workout can’t be one of those. Your body isn’t built to train that way; you’re gonna burn out, and you could get injured, or both.

There’s a place for some moderate intensity as well, so if I were focusing on heart rate, I would say in the 80s, so it’s hard but not max effort, and it’s more sustainable. When you’re in that 70 to high 80s range, we categorize that as building aerobic capacity. Overall, I suggest an approach with recovery, moderate intensity, and then high intensity every now and again to test yourself. 

The best cardio for fat loss

TM: How does cardio help with fat loss, and what types of cardio do you recommend?

Steve Stonehouse: I’m a big fan of high-intensity cardio. Sometimes, people think if some is good, more is probably better, but more isn’t always better. If I were putting a program together for six days a week, I’d have three days as some type of cardio-driven day, and three of those days I would have some version of resistance training. Maybe some days are heavier, and other days are a little lighter with higher rep targets and less rest.

Of those three cardio days, I’d recommend that one of them be a high-intensity max effort type HIIT session. Another could be hard with a heart rate in the 80s, but not max effort. That third cardio day could be more metabolic conditioning, like kettlebell swings, sled pushes, rower, or SkiErg, and things like that.

Ramping up muscle growth

TM: What types of exercise are the most effective for ramping up muscle growth?

Steve Stonehouse: We’re moving into a great space right now in fitness, and it seems like every 10 or 15 years, there’s this new movement. CrossFit first popped up and led the charge for metabolic conditioning and no days off. It’s the idea that if you still feel good at the end of a workout, you didn’t train hard enough. I think we’re phasing out of that and into wanting to lift heavy again. People who wouldn’t have touched a barbell ten years ago are lifting heavy now.

Keep in mind that heavy is a relative term. You can get stronger with some lighter dumbbells, but there are limits to that. A blend is nice, but you do need to include those times when you’re lifting heavy and challenging yourself at a low rep target.

Say, I’m going to do barbell deadlifts for five reps. If I can do eight, then that weight is too light. It’s intended to be a weight that you can’t get 15 reps of. There are advantages to lifting heavy with low-rep targets and longer rest times. For example, we’re going to do four sets of five reps of barbell deadlifts with two minutes of rest in between sets. If you can do more than five or six reps, that weight is too light. There’s a lot of value in lifting heavy.

TM: We know it’s probably difficult to choose, but what are your top three favorite fat-burning, muscle-building exercises right now?

Steve Stonehouse:

  • Barbell Zercher squat
  • Barbell deadlift
  • Flat barbell bench press

TM: How often should you work out to build muscle?

Steve Stonehouse: For the heavy session with five or six reps and longer rest periods, you could have a day each week that’s primarily focused on upper-body heavy strength training. Then, you could split it up and have another day that’s primarily focused on the lower body. You could do that, so you’re not in the gym for two hours; it’s more like a reasonable 45 or 50 minutes. If you were feeling ambitious, you could get a third one in toward the end of the week and have a bit of a mixed session where there’s not as much volume, but you have upper-body and lower-body focus. 

With that type of heavy volume, you’re going to need a decent amount of time to rest. So, if I were doing a heavy bench press today, I probably wouldn’t do that again until next week — same thing with squats, deadlifts, or any larger main lifts.

Incorporating sufficient rest days and progressive overload

TM: Are rest days important for the best results?

Steve Stonehouse: Yes. Rest and recovery are two different things. A recovery session would include a bit of activity, but at a lower intensity. Recovery is restoring to a natural, healthy state, and rest is inactivity. 

TM: With resistance training, do you recommend incorporating progressive overload, where you gradually increase the weights over time to develop muscle strength and mass?Steve Stonehouse: 100%. We do strength training regularly at BFT. We have a portion of our performance app, and you can enter your five-rep max. On different days, the performance app tells you how much weight you should be lifting on that day to appropriately follow that progressive overload model.

Skip the 10,000 Steps: The One Exercise That Matches a Full Day of Walking, according to a Fitness Coach

On Instagram, Zarina Manaenkova advised taking short intervals of squats could deliver the same impact as a full day of walking. “Ten squats instead of 10 thousand steps,” Zarina’s post read, referencing a study that equated ten squats every 45 minutes with 10,000 steps. Manaenkova explained the science behind her claim, stating, “When your muscles actively contract, they produce very important compounds that influence your brain, metabolism, and even your fat-burning processes. Meanwhile, a simple walk does not have this effect. So, if you want to stay young, squat.”
