How to Get More Benefits from 10,000 Steps per Day

Many of you are familiar with the 10,000-steps-a-day walking trend, but you may not know where it originated. The idea of walking 10,000 steps per day did not come from scientific research; rather, it came from a marketing campaign for a pedometer ahead of the 1964 Tokyo Olympics. Since the Japanese symbol for 10,000 looks somewhat similar to a person walking (see image below), the pedometer was named Manpo-kei or 10,000 steps meter, and the 10,000-step-a-day walking trend was born.

 

 

We know walking is good for us, but what do researchers have to say about this 10,000 number? Is this the right number of steps? What are the health benefits of reaching this number?

A 2023 research study showed 8,000 to be the sufficient number of steps to yield significant health benefits. In this study, participants who took 8,000 steps or more on one or two days during the week showed substantially lower cardiovascular and all-cause mortality risk.

Stanford Lifestyle Medicine Movement and Exercise pillar member Corey Rovzar, PhD, DPT, puts the 8 and 10 thousand numbers into perspective. “What is more important than hitting an exact number is that you’re moving more throughout the day,” says Dr. Rovzar. “If looking at a pedometer and trying to hit 8,000 steps will help you move more, then it’s a great tool, but rather than fixating on an exact step count, I recommend you think about your day and envision opportunities to move.”

Rather than walking all 8,000 steps in one go, which would take about 80 minutes at three miles per hour, Dr. Rovzar recommends walking the 8,000 steps throughout the day, such as in the morning and evening and after each meal. For example, you could split the 8,000 steps (80 minutes of walking) into four, 20-minute walks. If you stick to the 10,000-step goal (100 minutes of walking), that breaks down to five, 20-minute walks. This recommendation is good news for those who sit at a desk since taking several short walks during the workday is a perfect way to take a break. “It is important to note that all steps count! Even a few steps to the bathroom or to another room contributes to this overall count,” says Dr. Rovzar.

Ideas on How to Meet Your 10,000 Steps Goal:

  • Take the stairs instead of the elevator.
  • Walk more during errands by parking your car farther away from your destination or getting off the bus or train a stop early.
  • Walk more during your work day by taking a “walking meeting” or walking while on the phone.
  • Walking after each meal can help with digestion, blood sugar management, and cardiovascular health.
  • Walk every morning, evening, and during your lunch break. Even 10 to 15 minutes of walking can add up to 1,000 steps.
  • Catch up with a friend by going on a walk instead of meeting for coffee.
  • Use a step tracker to help you stay motivated and track your progress.

How to Get More Out of Your 10,000 Steps

If you’re already walking 8 to 10 thousand steps daily, you may be ready to take your walking to the next level. If so, Dr. Rovzar recommends adding modifiers to your walking routine to help you meet additional fitness goals, such as improving balance or building muscle.

Here are a few of Dr. Rovzar’s recommendations for intensifying your daily stroll and gaining more health benefits:

1) Cardiovascular (Endurance) Modifier:

Interval walking

Interval walking involves alternating fast and slow walking cycles. Researchers recommend five intervals of fast and slow phases, each lasting roughly three minutes. The effort expended should be 40 percent of your maximum effort for the slow phase and 70 percent for the fast phase.

2) Muscular Strength Modifiers:

Walk up and down hills or stairs multiple times

If you are looking for strength benefits, hills may become your new best friend. Walking hills or stairs not only has excellent aerobic benefits but also serves as a great form of strength training.

Add ankle and wrist weights or wear a weighted backpack

Another strength training modification is adding weight to your walk, either with ankle or wrist weights or by rucking. The term rucking originated during boot camp training and involves using weighted vests or backpacks while hiking or walking.

3) Balance Modifiers:

Take side steps

March (i.e., lift your knees as you walk)

Walk backwards

It is essential to perform balancing exercises as we age. Implementing side steps, marching, or walking backward are great ways to train your body to handle non-forward-facing movements, enhance joint mobility, and improve flexibility. Balance training is also an effective way to strengthen different muscle groups. For example, side steps engage your abductors, which are hip muscles involved in getting out of your car and transitioning out of bed in the morning.

4) Cognition Modifier:

Dual-task training

Cognition may also be enhanced with walking practices, like dual-task training. This practice involves performing a mental task while walking, such as talking to someone while walking, keeping step time to a metronome, or counting backward from 100. Combining the mental task with the physical action of walking forces the walker to increase concentration, which sharpens the mind and improves balance and stability.

Whole Body Health Benefits

In addition to the physical benefits walking offers, Dr. Rovzar says that walking improves mental clarity and well-being. Taking a step away from work and going on an outdoor walk can help you overcome mental roadblocks. Studies have found mental health benefits from walking outside in nature, including decreased cortisol levels, diastolic and systolic blood pressure, and pulse rate. While using a treadmill may be a great way to multitask and get in extra movement, there are considerable mental health benefits from taking a break outside, getting fresh air, and stopping to smell roses and pet dogs on your walk.

“We often strive to maximize our time working, but in reality, you might not be saving yourself time by omitting the breaks,” says Dr. Rovzar. “I recommend getting out of your work environment and going for an outdoor walk every couple of hours during the workday, even if it’s just five-minutes of movement to get your blood flowing.”

Practice of the Month:

Walk 5 Days per Week for 30 minutes with a Modifier

The US guideline for moderate physical activity is 150 minutes per week (which breaks down to five 30-minute brisk walks with a modifier per week). To ensure you’re improving muscle strength, balance, endurance, and cognition every week, Dr. Rovzar recommends assigning different modifiers to different days.

Sample Walking Routine (30 minutes per walk):

Monday: Walking up and down hills on Mondays (endurance)

Tuesday: Rucking (strength)

Wednesday: Incorporating intervals of side-stepping, marching, and walking backward (balance)

Thursday: Interval walking (endurance)

Friday: Adding ankle and wrist weights (strength) while counting backward from 100 with each step (cognition)

 

If a 30-minute walk seems too daunting, Dr. Rovzar suggests starting with 10 minutes of walking and incrementally working your way up to 30 minutes daily. “Much of this comes down to goal setting,” she says. “If you set too lofty of a goal, it becomes unachievable, but if you break your goal down to an amount that seems feasible and perhaps try it just for a week, it becomes more likely you will remain consistent in attaining it.”

How Exercise Improves Microbiome Health (and Vice Versa)

, ,

By Mary Grace Descourouez, MS, NBC-HWC 

The human gastrointestinal tract is home to trillions of microorganisms that create the gut microbiome. The gut is where the body digests and absorbs nutrients from our food and, therefore, where we get our energy to perform daily human functions. Microbiota are microorganisms in the gut microbiome that help the body harvest energy, fight pathogens, and regulate immunity. Having a high diversity of microbiota helps us to process food effectively, providing the substrates and nutrients needed to keep us going throughout the day. Therefore, it is crucial to make lifestyle choices that promote a healthy and diverse microbiome.

Many people know that a nutrient-rich diet contributes to a healthy microbiome, however, research shows that movement and exercise may also have a positive effect, and, inversely, a healthy microbiome may improve athletic performance.

“It is a relatively new field, but available studies suggest a bidirectional relationship between performance and the health of the microbiome,” says Anne Friedlander, PhD, Exercise Physiologist and Assistant Director of Stanford Lifestyle Medicine. “People who are more active have a healthier and more diverse microbiome, and that, in turn, provides the person with the nutrients required to enhance physical and cognitive performance. It is a mutually beneficial relationship.” 

How Exercise Improves the Microbiome

Movement and exercise have many benefits on our overall health, including positive effects on the microbiome. Studies show that athletes have a more diverse microbiome composition than non-athletes. Microbiome diversity is important because it helps make our food’s nutrients more bioavailable for optimal functioning of the body.

Another study found that active women were associated with high microbiome diversity compared to sedentary women. Specifically, researchers found that consistent physical activity increased the amount of 11 genera of “good” bacteria, including Bifidobacterium spp, Roseburia hominis, Akkermansia muciniphila, and Faecalibacterium prausnitzii. 

How the Microbiome Improves Athletic Performance

Just as exercise positively impacts the microbiome, emerging research shows that microbiome health may also play a part in enhancing exercise performance.

For example, a 2019 study showed that a specific gut microbiota in marathon runners may have enhanced their athletic performance on race day.  In this study, researchers collected fecal samples from the runners before and after the marathon and compared them to microbiota of non-runners. The “good” bacteria Veillonella emerged as the most common in the runners, especially post marathon. Veillonella is a bacterial strain that converts exercise-induced lactate into propionate, which is a natural enzymatic process known to enhance athletic performance.

Researchers then put the Veillonella bacteria from the marathon runners into lab mice who underwent a treadmill exertion test to investigate the hypothesis that this bacterial strain enhances athletic performance. The results showed the mice improved performance by 13 percent after inoculation. This study is one of the first to infer that a healthy microbiome could enhance athletic performance.

“We have a long way to go to fully understand the complex system that involves the microbiome and athletic performance, but the early data look promising regarding gut health and exercise,” says Dr. Friedlander.  “Exercise, along with eating fermented foods and fiber, is a great place to start if you want to improve your gut health and overall health.”

Supplements for Elite Athletic Recovery

, , ,

By Caitlin Aguirre, Adrian Vallejo, Matthew Kaufman, MD

This blog is part of our Supplements newsletter. If you like this content, sign up to receive our monthly newsletter!

Key Takeaways:

  • It is recommended to consult with a medical professional before taking the supplements listed in this blog.
  • Branched Chain Amino Acids stand out as a well-supported supplement for athletic recovery, aiding in faster physical recovery, decreased fatigue perception, and maintenance of lean mass. Recommended dosages range from 10 – 30 grams per day.
  • L-theanine shows promise in mental recovery post-exercise, with suggested doses ranging from 50 – 200 mg per day. 
  • N-acetylcysteine’s role in reducing perceived muscle soreness remains uncertain, with doses of 1200 – 1800 mg per day utilized for supplementation within existing studies.
  • Turmeric shows promise in alleviating muscle soreness at doses ranging from 1.5 – 5 grams of turmeric extract daily, although research is conflicting. Supplementing with piperine (black pepper) may enhance its effectiveness.
  • Ashwagandha holds the potential to reduce muscle soreness and improve athletic and mental recovery at a dose of 600 mg daily. While research on its effects is limited, current evidence suggests it’s generally safe for supplementation.

For high-performance athletes, achieving peak performance is not solely a result of pushing one’s physical limits. Even the best competitors experience fatigue, musculoskeletal pains, exercise-induced muscle dysfunction (EIMD), and delayed-onset muscle soreness (DOMS) that may impact their ability to sustain maximal training efforts and combat injury. In response to these physical ailments, often a sign of our bodies adapting to higher training loads, high-performance athletes have mastered the practice of athletic recovery.

The principles of athletic recovery can be thought of as a pyramid having a base of quality sleep, balanced nutrition, and hydration. These elements are the foundation upon which adapting to the demands of intense training is built. However, as committed athletes refine their sleep hygiene, prepare macro-friendly meals, and hydrate appropriately, they often look to ascend this metaphorical “athletic recovery pyramid” by utilizing nutritional supplements to gain an edge over their competitors. Previous literature has estimated that 40 – 100 percent of trained athletes have employed nutrient supplementation, depending on the definitions of trained athletes and supplementation.

In this blog post, we’ll explore the role of popular anti-inflammatory and antioxidant nutritional supplements, including BCAA’s, L-theanine (LTE), N-acetylcysteine (NAC), Turmeric, and Ashwagandha, and what role they may play in athletic recovery.

What are Branched Chain Amino Acids (BCAAs)?

BCAAs are a specific class of amino acids that have branched side chains. These include amino acids like leucine, isoleucine, and valine. Studies suggest that BCAAs are among the most commonly used supplements in trained athletes. These essential amino acids are broken down for fuel during exercise, and supplementation has been thought to provide substrate for anabolic (muscle-building) processes to prolong energy sources and protect against muscle damage and fatigue. Rather than a supplement, you may also consume BCAAs by eating foods high in leucine, such as salmon, chicken, cottage cheese, eggs, nuts, lentils, and beans.

Potential Benefits of BCAAs for Athletic Recovery

Our Recommendations

BCAAs are a supplement well supported by scientific literature that can shorten recovery time and decrease perceptions of fatigue. As an athlete, this may maximize athletic results by supporting the ability to continue long training sessions and return to sport quicker!

Dosing

Studies have shown positive outcomes with BCAA supplementation ranging from 0.087 – 0.22 grams per kg of body weight per day for at least eight days. Positive effects were also shown when the athlete took 20 grams one hour prior to exercise. While there’s no apparent consensus on the optimal dosing strategy, studies show that taking between 10 – 30 grams per day had no noted ill effects.

What is L-theanine (LTE)?

LTE is a non-proteinogenic amino acid that is structurally similar to glutamate. It is a primary component of the Camellia Sinensis plant, which is used to make green tea, and can also be found in smaller quantities in other foods, such as mushrooms, apples, and red wine.

Potential Benefits of LTE for Athletic Recovery

Our Recommendations

Since mental restoration following strenuous training or competition is vital for preventing burnout and enabling athletes to maintain a consistent level of high-intensity training, we recommend a supplement that provides mental recovery. Current evidence shows that LTE has the potential to aid mental recovery, however, further studies on larger sample sizes of athletes may be necessary for a comprehensive recommendation. 

Dosing

Although there is no clear agreement regarding the best dosing strategy for LTE, the studies examined in this review have demonstrated physiologic benefits with doses ranging from 50 – 200 mg per day. Within this range, LTE is considered safe for consumption and has demonstrated no toxic effects in both human and rodent studies.

What is N-acetylcysteine (NAC)?

NAC is a synthetic derivative of the naturally occurring amino acid L-cysteine. In the body, L-cysteine and NAC have direct antioxidative properties and serve as precursors to glutathione (GSH), another powerful antioxidant that prevents excessive molecular damage.

Potential Benefits of NAC for Athletic Recovery

  • May reduce perceived muscle soreness – Numerous studies evaluating the effects of NAC supplementation have shown mixed outcomes regarding the benefits of its antioxidative properties and ability to reduce muscle soreness.

Our Recommendations

Further investigations are necessary before clear conclusions can be drawn about whether NAC supplementation improves athletic recovery by decreasing perceived muscle soreness. 

Dosing

While there is no standardized dosing strategy for NAC supplementation, existing studies evaluated doses between 1200 – 1800 mg per day, with a loading period of at least three days. It’s important to note that exceeding 70 mg per kg of body weight may lead to negative side effects, including gastrointestinal upset, so it’s essential to monitor dosage and potential reactions carefully.

What is Turmeric?

Turmeric, Curcuma longa, is a commonly used medicinal herb that contains curcuminoids, including curcumin. Curcumin has been shown to have antioxidant effects and is associated with pain reduction, anti-inflammation, and chronic disease prevention and treatment.

Potential Benefits of Turmeric for  Athletic Recovery

  • May reduce perception of muscle soreness – Despite conflicting literature, numerous studies evaluating the effect of turmeric on whole and lower-body soreness and single-leg squat pain scores have found that its supplementation significantly reduced measures of muscle soreness. However, one recent meta-analysis found no significant effects on exercise-induced muscle damage or delayed onset muscle soreness. 
  • Taking piperine (black pepper) along with turmeric has been shown to potentially increase its bioavailability and may increase the efficacy of this supplement.

Our Recommendations

According to the literature, turmeric, or curcumin, seems to be a safe supplement for potentially reducing perceived muscle soreness following exercise. However, further study is needed to confirm the extent of turmeric’s efficacy due to the presence of conflicting research. It’s worth noting that simultaneously supplementing with piperine (black pepper) may positively influence its effectiveness.

Dosing

There is no standardized dosing strategy, however, doses ranging from 1.5 – 5 grams of turmeric extract daily, perhaps with piperine (black pepper), may be helpful in exercise recovery. Higher doses of 10 mg and above have been shown to produce mild negative side effects, including headache, diarrhea, yellow stool, and rash. Take caution when consuming higher doses is warranted as the literature on safety and side effects is limited. 

What is Ashwagandha?

Ashwagandha, or Withania somnifera, is an adaptogenic herb commonly used in Ayurvedic medicine. It has gained traction within the fitness community due to some preliminary studies showing an association between the supplement and enhancing muscle strength, muscle endurance, and cardiorespiratory fitness while counteracting chronic fatigue, weakness, nervous exhaustion, and premature aging. The mechanisms by which ashwagandha may improve physical recovery in humans are not well understood but are hypothesized to be at least partially due to antioxidant properties and endocrine effects.

Potential Benefits of Ashwagandha for Athletic Recovery

  • May reduce perception of muscle soreness – Supplementation has been found to decrease one’s perception of muscle soreness after exercise. This effect on muscle soreness is attributed to its antioxidant properties and its hypothesized ability to be converted into testosterone and DHEA, however, further study is needed to elucidate the exact mechanism.
  • May reduce recovery time – While evidence for this effect is minimal, two studies found significant improvement in participants’ perceived athletic recovery experiences. 
  • May promote mental recovery – One study found that supplementation lowered participants’ perception of general stress, fatigue, and lack of energy and improved general well-being scores compared to placebo.

Our Recommendations

The literature on the effects of ashwagandha on athletic recovery is minimal, however, current studies suggest that it is a safe supplement that may reduce one’s perception of muscle soreness and improve athletic and mental recovery following exercise. 

Dosing

There is no standardized dosing strategy, however, studies show that 600 mg of ashwagandha daily may be helpful in exercise recovery. Common side effects may include drowsiness, epigastric discomfort, and loose stools. Less common effects include mild CNS depression, increased thyroxine levels, hallucinations, blurred vision, vertigo, nausea, decreased appetite, constipation, hyperacidity, nasal congestion, dry mouth, hyperactivity, nocturnal cramping, skin rash, and weight gain.

Everything You Need to Know About Creatine

,

By Carly Smith, BS, MPH(c)

This blog is part of our Supplements newsletter. If you like this content, sign up to receive our monthly newsletter!

A recent analysis done by members of the Stanford Lifestyle Medicine team on how different supplements impact sports performance, highlighted creatine since it has been vastly researched and shown to improve muscle strength.

“What many do not realize is that supplements, like creatine, can be beneficial for more than just professional athletes and bodybuilders,” says Matthew Kaufman, MD, member of the Stanford Lifestyle Medicine Exercise and Movement research team and lead author of “The Impact of Supplements on Sports Performance for the Trained Athlete: A Critical Analysis.”

What is Creatine?

So, what is creatine? Creatine is a natural amino acid that people can gain in their diet with foods high in protein or through supplementation. Mechanistically, creatine supports powerful muscle contractions, which is why it is popular among bodybuilders. After digestion, creatine-phosphate is stored in skeletal muscle until the onset of quick, intense physical activity. Once activity is initiated, it is used to rapidly phosphorylate ADP into ATP, which drives fast-twitch muscle contractions, the primary drivers of quick, forceful exercise movements like weight lifting and sprinting.

According to the analysis, athletes that also depend on fast, powerful movements and mobility, like soccer and basketball players, may also benefit from increasing their creatine intake. Its ability to heighten muscle performance is continuing to be tested and is being used by many to increase the size and strength of their muscles.

“What’s nice about creatine, especially compared to other supplements, is how much it has been studied. It has robust, promising data that shows it can really improve athletic performance and muscle composition,” says Dr. Kaufman. “Plus, it can help muscle growth and performance for all different types of people.”

Creatine Is Not Just for Bodybuilders!

Creatine may also be a good supplement for plant-based athletes. The analysis found evidence that vegetarian athletes improved more than omnivorous athletes with creatine supplementation in terms of muscle power output and lean muscle mass, therefore plant-based athletes could consider supplementation to support their athletic performance.

Creatine is also recommended for older individuals to support muscle sarcopenia. With age, many people experience a loss of muscle vitality, which heightens risk of falling and injury. Research published in the Journal of Clinical Medicine indicates that creatine supplementation may help older adults maintain muscle vitality. It suggests that there could be significant benefits from supplementing their diets with creatine for an “anti-aging” effect for the body.

How Much Creatine Do I Need?

Whether taking creatine supplements for athletic performance or daily functioning, it is important to know what the International Society of Sports Nutrition’s (ISSN) recommended dosing strategy is. Their recommendation begins with all individuals taking 5 grams of creatine, four times per day (20 g total per day) for about a week. This first week is called the loading stage, which helps many people adjust to the supplement before experiencing any physical changes. Next, ISSN recommends maintaining a dose between 3-5 grams daily. Males and larger athletes may need 5-10 grams daily to maintain their body’s creatine stores.

People considering taking creatine should be aware of some potential side effects. Studies report the possible side effects of increased water retention and airway sensitivity in elite athletes, the latter suggesting the need for further research on how creatine affects those with asthma. We recommend consulting with your physician ahead of time so they can tailor the ISSN’s dosing recommendations for your specific needs.

Overall, creatine supplementation may be promising for many individuals, bodybuilders or not, looking to improve the power of their muscles.
