Faster knee for better walking
Scientists find knee extension velocity while seated strongly predicts walking performance in elderly patients after total knee arthroplasty
Scientists measured gait function, knee extension velocity while seated, quadriceps strength, knee range of motion, and knee pain in 186 total knee arthroplasty patients to identify the most important determinant of postoperative gait function.
« Faster knee for better walking
Newswise — Osaka, Japan – “Speed or strength, which is more important?” may be a critical question for not only athletes but also knee surgery patients. Osaka Metropolitan University scientists have revealed that knee extension velocity while seated is a stronger predictor of walking performance than muscle strength in elderly patients after their total knee arthroplasty (TKA) surgery.
TKA is the most common surgical intervention for knee osteoarthritis, a musculoskeletal disorder that mainly progresses with age. This surgery has been shown to be effective in relieving pain and restoring joint range of motion; however, TKA-enabled improvement in gait function may not be sufficient. Although the strength of the quadriceps—a muscle used to extend the knee—has been deemed to have a significant effect on postoperative gait function in TKA patients, there are many cases in which gait function does not improve even after quadriceps strength is restored. This raises a need to identify other factors influencing gait function.
A research team led by Professor Akira Iwata, from the Graduate School of Rehabilitation Science at Osaka Metropolitan University, hypothesized that the movement velocity of knee extension (i.e., knee extension velocity) is a strong determinant of gait function in TKA patients, and tested this hypothesis on 186 elderly patients who underwent TKA. Measurements were taken before and at 2 and 3 weeks after surgery and included gait function (gait speed and Timed Up and Go test), knee extension velocity, quadriceps strength, knee range of motion, and knee pain. Multiple regression analysis was performed to analyze the relationship between gait function and other variables.
The results show that the knee extension velocity on the operated side was the most important predictor of gait function in the participating patients. The findings were published in PLOS ONE.
“Thus far, rehabilitation programs aimed at recovering gait function after TKA surgery have focused on training to improve quadriceps strength,” explained Professor Iwata. “However, this study’s results suggest that training to enhance knee extension velocity on the operated side could be effective. We will continue to examine the effects of rehabilitation that concentrates on movement velocity.”

4 Daily Brain Health Habits for Better Cognition
Daily Brain Health Habits: Your brain works hard for you, so it’s only fair to return the favor by practicing simple everyday habits to keep this important organ strong and thriving. Start by tweaking your daily routine to focus on these four habits and eating nourishing recipes like California Grape and Sardine Avocado Toast.
4 Daily Brain Health Habits for Better Cognition
(Feature Impact) Your brain works hard for you, so it’s only fair to return the favor by practicing simple everyday habits to keep this important organ strong and thriving.
Start by tweaking your daily routine to focus on these four habits.
Prioritize Sleep
Getting quality sleep is vital for proper brain function. If you find you’ve slipped into the habit of staying up later than you should or notice your sleep being disrupted during the night, those are signs to revisit your sleep hygiene practices. Start by establishing a regular bedtime and wake-up time that will give you the recommended 7-9 hours of sleep. Turn your bedroom into a comfortable refuge from the world – keep it cool and dark, and set up fans or noise machines if you need them to quiet your mind. Avoid consuming caffeine or alcohol too close to bedtime and try switching to a book instead of a screen when it’s time to wind down.
Eat Smart
Just like the rest of the body, the brain is nourished by food. Some of its favorite foods are options rich in healthy fats like fish, avocado, olive oil and nuts, as well as vegetables like leafy greens, which offer carotenoids, and fruits such as grapes, which deliver antioxidants and other polyphenols.
Combine several of these powerful brain-boosting foods at once with this California Grape and Sardine Avocado Toast recipe. The fish is rich in omega-3 fatty acids and the avocado offers a boost of healthy unsaturated fat, while the grapes add protective dietary flavonols, which may help promote anti-inflammatory and beneficial antioxidant activity.
A study published in the scientific journal “Neurology” found a higher intake of certain flavonols – including three naturally found in grapes – is associated with a 48% decreased risk of developing Alzheimer dementia.
Get Moving
Adding even more proof that what’s good for your body is good for your mind, getting regular exercise is one of the best things you can do for your brain. Motivate yourself by choosing a form of movement you genuinely enjoy, whether it’s a daily walk on a nearby nature trail, a dance class, a bike ride or a heart-pumping workout video.
Challenge Your Mind
Don’t forget to give your brain its own workout, too. Doing something mentally stimulating every day is a great way to keep yourself sharp, and there are plenty of ideas to choose from. Try learning a new language, picking up a musical instrument, playing a mind-engaging card or board game, doing a puzzle, reading a book or immersing yourself in a creative writing or art project. The options are nearly endless, and if you want to make your brain extra happy, you can snack on handfuls of grapes as you enjoy your hobby.

5 Ways to Naturally Support Summer Energy and Focus
Naturally Support Summer Energy with five simple daily habits designed to boost focus and help you enjoy longer days, vacations, and summer events without feeling tired or distracted.
5 Ways to Naturally Support Summer Energy and Focus
(Feature Impact) Summertime means sunshine, longer days, family vacations and social events everywhere you look – but summer can slip away if you feel too tired and distracted to make the most of your experiences.
According to a survey conducted by Atomik Research on behalf of Botanic Tonics, many adults ages 21 and older struggle to feel fully present in summer activities. Nearly half of respondents said having enough energy and a clear mind would help them get more enjoyment out of the summer moments that matter most.
With that in mind, here are five simple daily habits to support your energy and focus throughout the rest of the summer season.
Improve Your Sleep Quality
It might sound obvious, but getting better sleep should be a top priority for anyone trying to harness more physical and mental energy throughout the day. Keep your bedroom cool, dark and quiet; avoid consuming caffeine too close to bedtime; and wind down with a relaxing routine like reading or yoga.
Get Regular Exercise
Even though a workout consumes energy in the short term, it pays you back with dividends. Just 30 minutes of movement a day – including favorite summer activities like swimming or playing games in the yard – can improve your mood. Physical movement also helps reduce stress, which was a reported obstacle for 33% of survey respondents who wished they could be more present with friends and family during the summer months.
Stay Hydrated
When the weather is hot, it becomes more important to stay on top of your hydration. Even mild dehydration can negatively impact your energy and focus. When you’re out of the house, bring a reusable water bottle and set reminders to drink regularly, especially during and after outdoor activities.
Limit Device Usage
When you’re feeling sluggish, it can be tempting to collapse on the couch or in bed to scroll on your phone or watch TV. There’s nothing wrong with screen time in moderation, but digital fatigue is real and it can drain your energy and disrupt your sleep. Plus, 49% of surveyed adults said social-media-driven FOMO (“fear of missing out”) made it harder for them to enjoy their summer experiences in the moment.
Try Botanical Energy Offerings
When energy levels start to dip, it’s easy to reach for a cup of coffee, a sugary energy drink or soda. Products made with thoughtfully sourced botanical ingredients offer a different approach. For example, Botanic Tonics’ “feel free” kava-centric supplements are designed to deliver chilled energy: a unique combination of energy, focus and elevated mood.
For smooth, sustained energy without caffeine jitters or sugar crashes, try KavaMaté, crafted with noble kava root and yerba maté. For those looking to elevate their mood and enhance focus, feel free Classic is thoughtfully crafted with noble kava root and natural whole leaf kratom – never synthetic ingredients, alcohol or concentrates.

Strong at Every Age: How Women Can Help Combat Muscle Loss
Combat Muscle Loss: Aging is inevitable, but losing muscle and mobility doesn’t have to be. Consider these tips to help women protect their muscle health.
Strong at Every Age: How Women Can Help Combat Muscle Loss
(Feature Impact) Aging is inevitable, but losing muscle and mobility doesn’t have to be. For many women, maintaining strength, independence, energy and mobility are top priorities as they get older, particularly as they deal with the mental and physical responsibilities that come with working, caregiving, keeping up with friends, hobbies and enjoying an active lifestyle.
In fact, 58% of women in the United States are actively focused on staying healthy as they age, according to a recent survey commissioned by Viactiv, a line of award-winning supplements for women known for their unique formats and flavors. However, 73% of respondents weren’t aware of sarcopenia, or age-related muscle loss. According to the “International Journal of Women’s Health,” age-related muscle loss often begins between ages 30-35, with women losing 3-8% of their muscle mass per decade and increasing to 5-10% loss per decade after age 60.
Hormonal changes, decreased activity levels, stress, poor sleep and inadequate nutrition can all contribute to the decline in muscle, which can also negatively impact balance, bone health, metabolism, posture and everyday mobility.
Yet, despite 70% of women reporting some level of concern about muscle loss, 54% are unsure how to protect their muscle health.
“Women want to stay strong, active and independent as they age, but many are getting mixed messages about what actually supports long-term muscle health,” said Dr. Tania Elliott, a dual board-certified physician in internal medicine. “A lot of women are already making healthy choices like walking and staying active, which is a great start. However, maintaining muscle health really requires a more complete approach, and one that starts earlier than most women think, which is in your 30s.”
Prioritize Strength Training
Many women report barriers such as lack of time (15%), feeling overwhelmed (23%) or simply not enjoying exercise (23%). The key is finding realistic, sustainable habits. While walking and cardio exercise aid in heart health, which 58% of survey respondents report already engaging in, strength training is one of the most effective ways to preserve and build muscle as you age. Still, just 34% of women report doing strength or resistance training.
You don’t need an intense fitness regimen to support healthy aging. Aiming for at least two strength-focused workouts a week – lifting weights, using resistance bands, practicing weight-bearing yoga or doing bodyweight exercises like squats and pushups – that target major muscle groups can help maintain muscle health. The goal is to fatigue your muscles during sets so they build.
Fuel Muscles with Proper Nutrition
Exercise is only part of the equation. Muscles also need proper nutrition to recover and stay strong. Protein plays a critical role in maintaining muscle mass, especially as women age. Incorporating high-quality protein throughout the day, such as eggs, Greek yogurt, fish, lean meats, beans, lentils, nuts and seeds, may help support muscle repair and overall strength.
Support Healthy Aging with Supplements
In addition to a balanced diet and exercise, some women may consider supplements that support healthy aging and energy production, including CoQ10, which is a naturally occurring antioxidant that helps cells produce energy. According to research published in “The Journal of Nutrition, Health and Aging,” because muscles require significant energy to function, CoQ10 shows potential for managing sarcopenia by improving mitochondrial function and reducing oxidative stress.
An option like Viactiv CoQ10 Cardio Complete, available in a tasty fruit-flavored chew, can help support heart health, muscles, nerve function and daily energy. Enhanced with vitamins D3 and K2, it provides daily essential nutrition for women without the need to swallow a large pill.
Practice Healthy Habits
Muscle health is influenced by more than workouts. Sleep, stress management and daily movement all play important roles. Adopting some simple habits, including prioritizing quality sleep, stretching regularly, staying properly hydrated, reducing sedentary time throughout the day and practicing stress-management techniques, like yoga, meditation or deep breathing, can help aid in healthy aging, including maintaining muscle.
The earlier women begin prioritizing muscle health, the better positioned they may be to maintain strength and mobility as they age. Visit Viactiv.com for more information and resources to help combat muscle loss.
