Exercise to Prevent Falls!

 


As people age one of the biggest threats to their health and independence is falling.  A brief review of the statistics on falls provides a sobering view of the threat.

Falls are the #1 cause of death as a result of unintentional injury among people 75 and older and the #2 cause of death as a result of unintentional injury among people age 65 – 74.

Falls are the #1 cause of non-fatal unintentional injuries treated in hospital emergency rooms in every age group except ages 15 – 24.

Fall result in the second most expensive worker’s compensation claims with an average cost of $23,929.

One out of every three people older than 65 will fall this year.

50% of the people older than 65 who have fallen will fall again in the next 12 months.

Most falls are unreported (even serious falls) because seniors fear losing their independence, and many seniors would rather die than lose their independence.

The treatment of osteoporosis with drugs is very ineffective at preventing fractures because it does nothing to prevent the primary cause of fractures which is falls.

Modifiable Risk Factors for Falls

Strength (in particular lower body and core strength)

Mobility (of ankle, knee and hip in particular)

Fear of falling from previous fall/s resulting in altered gate and restricted activity levels which further increases fall risk

Poor Balance which has three systems (visual, inner ear, proprioception)

Impaired Vision

Cognitive Status/Mood

Environmental Factors (slippery floors, rugs, poor lighting, etc.

Medication Side Effects

Exercise for Fall Prevention

Exercise can help address several fall risk factors including strength, mobility, balance along with improved cognitive status.

The most effective exercise boosts lower body and core strength while including a balance component that can be adjusted to each individual’s current capabilities.   This exercise should be weight bearing whenever possible and functional in nature.

reACT – Rapid Eccentric Anaerobic Core Trainer

One of the finest ways to address the exercise component of a fall prevention program is the use of the reACT Trainer.   The reACT Trainer provides a no impact training stimulus with a self-selected range of motion and allows for progressive balance challenge to fit just about any ability level.  

The reACT Trainer is a functional eccentric trainer meaning it provides eccentric dominant exercise that is highly functional in nature with strong emphasis on integrated functional movements in multiple planes of motion with the ability to adjust movement speed to increase or decrease the challenge level.   It is also a very safe training modality.

How to Prevent Sleep Problems from Fall Time Change!


It’s that time of year again – time to fall back and set our clocks back one hour.  Resetting clocks in devices is simple.  Unfortunately, your body clock is not nearly as easy to reprogram.  This comes with some serious health consequences.  An hour time shift does not seem like a lot, but your body runs on a tight schedule and this one-hour change throws us off.

Scientists have documented that the shift to daylight saving time in the spring, when we lose an hour of sleep, is linked to an a much higher rate of attacks and car accidents.  Although we gain an hour to sleep – the change throws off the sleep cycle and that is where all the problems come from.

Over the last 20 years, scientists have documented that, in addition to the master clock in our brains, every cell in our body has a circadian rhythm and time-keeping mechanism. The body and cell’s circadian rhythm help regulate important functions such as sleep and metabolism. And increasingly, there's evidence that when our habits — such as when we eat and sleep — are out of sync with our internal clocks, it can harm us.

When we disrupt our routines with erratic sleep or eating habits, it can increase the risk of metabolic disease. For instance, overnight shift workers are at much higher risk of developing diabetes and obesity. Research also shows that kids who don't have set bedtimes and mealtimes are also more likely to become overweight.

As days get shorter with less daylight, it's easy to fall into bad habits, and regulating light exposure is key to regulating circadian rhythm.    

Maximize Exposure to Bright Light During the Day

Maximize your exposure to daylight in the morning hours since it gets dark so early in the evening.   This simple step is every bit as powerful as avoiding blue light at night.   Ideally get outside immediately upon waking – just five minutes of outside light can do the trick!    

Outdoor sunlight is about 1500 lux on a cloudy and 100,000 lux on a sunny day while indoor lighting typically maxes out at 500 lux!    Bright OVERHEAD light is the primary signal to shut-down melatonin production and wake up.    

If it is too cold to go outside consider buying a 10,000-lux UV free light – ideally one that you can set to shine down on your face from above you.    

Minimize Evening and Nighttime Light

Exposure to light and electromagnetic fields from computers, phones, tablets, and T.V.’s all act as a stimulant, so it is important to minimize nighttime light exposure and blue light exposure in particular.  Blue light comes from artificial lighting.   Blue wavelengths – which are beneficial during daylight hours because they boost attention, reaction times, and mood – are disruptive at night.   Energy efficient lighting is packed with blue light as are our electronics.

Turn off lights or dim them as much as possible.   If you must use a computer or your phone install blue light filtering programs on both that will adjust the amount of blue light emitted by your computer, phone, and tablets.    Flux – https://justgetflux.com is a free program for your laptop or tablet and the Twilight app for your phone.   Both allow you to set times and adjust blue light output of your devices automatically based on time of day! 

You can also buy blue blocking glasses to use in the evening.   This may seem gimmicky but there is very well-done research supporting the effectiveness of reducing blue light in the evening through these and other measures!

For night-time bathroom trips use a red-light nightlight as redlight does NOT disrupt sleep which is why you see it used by the military on ships and submarines!

Avoid Alcohol!

Alcohol intake is extremely disruptive to sleep and for many just eliminating it results in much higher sleep quality within a week. Consider cutting down or completely eliminating alcohol intake particularly during the work week!

Stop all food and beverage by 8pm!

Ideally stop all food and beverage intake 3 hours before bed – late food intake can create digestive issues and late beverage intake can force bathroom trips disrupting your sleep.

Stay on a consistent sleep/wake cycle!

Get up and go to bed at the same time each day – this trains the body and mind.   It is NOT a good idea to sleep in on weekends – this just disrupts your circadian rhythm.

Minimize Caffeine intake after 10am!

There are slow and fast caffeine metabolizers and if you are a slow metabolizer it is critical to stop any and all caffeine intake by 10am!   

Exercise!

Yes – it’s true – for many a consistent exercise habit will dramatically improve sleep quality and duration!

Finish your morning shower with a cold shower!

While this may seem unpleasant at first cold showers dramatically ramp up the secretion of norepinephrine which is the brains primary stimulant.  See this blogpost for the many benefits of cold showers:  http://workoutanytime.blogspot.com/2022/04/can-cold-showers-improve-exercise.html

How to Enjoy Halloween Candy without Going Overboard!

 

In the big picture of weight loss it is not what we do on the occasional holiday that really determines our weight it is the week in week out eating and drinking habits that determine our weight.   That being said if you are not careful you can eat/drink a ton of calories in one day which then turns into weeks of too many calories during the holidays starting with Halloween.

The key is to plan and know what you are eating!   Candy can be confusing because of all the different snack sizes that are so prevalent during Halloween.      It is very easy to assume because you are eating snack size candy that it is not that bad, and this is true if you are not eating many pieces!    Before you eat candy see how many calories you are eating – it takes less than a minute to google calorie, sugar, and fat content for just about any common Halloween Candy.

Here are some examples:

Nestle’s Crunch Bar (60 calories) - 6 minutes of brisk aerobic exercise to burn off!

Kit Kat Bar (70 calories) - 8 minutes of brisk aerobic exercise to burn off!

4 Snickers Mini Bar (170 calories) - 18 minutes of high intensity exercise to burn off!

Full Size Twix Bar (80 calories) - 6 minutes of continuous kettlebell swings to burn off!

4.2 Oz Candy Corn (450 calories) - 4 – 5 miles of walking to burn off!

2 Peanut Butter Cups (210 Calories) - 2 miles of running to burn off!

So eating a little candy is no big deal, BUT if you are not watching how many pieces/containers you eat you can quickly rack up a ton of calories that would take more than an hour of vigorous exercise to burn off!

Plan your candy intake and know what you are going to eat and enjoy it!   The other key is have candy after a meal so you are not really hungry – candy and hunger make for a really bad combination!

Exercise and Time Restricted Eating to Prevent Breast Cancer!

 

Research shows that exercise is an important step in the prevention of breast cancer!  There are many studies that show strong evidence that exercise lowers the risk of breast cancer (along with colon cancer, kidney cancer, bladder cancer, esophageal and stomach cancers!).

There is also strong evidence that exercise reduces anxiety, depressive symptoms, and fatigue in cancer patients.   Studies show that regular exercise reduces your risk of breast cancer by 20 – 30% with a 38% reduced risk of invasive breast cancers.

Studies also show that breast cancer patients with higher exercise levels have 29 – 41% lower risk of dying from breast cancer.

How Exercise Fights Cancer

Exercise has direct and powerful effects on human physiology that directly lower cancer risk including:

Improved insulin sensitivity – insulin resistance is directly linked to cancer growth and spread!

Improved blood circulation driving more oxygen into cells and helps the liver detoxify cancer causing substances.

Improved mitochondrial function – mitochondria are the energy factories of the cells and healthy mitochondria are key to prevention of many chronic diseases including cancer.

Decreased bodyfat levels – excess bodyfat produces copious amounts of estrogen and being overweight is an independent risk factor for breast cancer for this reason.

Improved immune function – a strong immune system is primed to recognize and destroy cancer cells before they form tumors!

Time Restricted Eating and Breast Cancer Prevention

Time restricted eating is exactly what it sounds like:  restricting your intake of food to a certain period of time each day.    Most Americans eat something every two hours for 16 – 18 hours per day.     Time restricted eating involves shortening this “feeding window” to somewhere between 8 and 12 hours per day.     

In the course of our evolution humans spent hundreds of thousands of years without constant access to food, and even as recently as the 50’s most people only ate two times per day.  Our bodies were not designed to have constant food intake all day, every day and doing so causes problems.

Every time we eat we secrete insulin which is necessary to absorb nutrients into our cells.  However frequent insulin secretion is one of the reasons so many Americans develop insulin resistance which frequently progresses to adult onset diabetes aka type 2 diabetes.   Woman with type 2 diabetes have a 23% higher risk for developing breast cancer and a 30.8% higher risk of breast cancer mortality

There is considerable research linking high evening/night-time calorie intake to elevated insulin resistance and inflammation both which drive breast cancer.

Enter Time-Restricted Eating where you simply restrict calorie intake to 11 - 12 hours per day - ideally having your first meal early in the day and finishing your last meal 11 hours later.   For example, an eating window of 7am - 6pm or 8am - 7pm.   Research has shown that this simple step can dramatically improve insulin sensitivity and inflammation and lower breast cancer risk.

A recent study analyzed data from the Women’s Healthy Eating and Living study and found that breast cancer survivors who didn’t eat for at least 13 hours overnight had a 36% reduction in the risk of recurrence and were 21% less likely to experience breast cancer related mortality. 

The proposed mechanism is reduced insulin levels and improved insulin sensitivity, and this makes perfect sense because elevated insulin levels and decreased insulin levels are directly linked to cancer growth. Each 2-hour increase in nightly fasting was linked to progressively lower hemoglobin A1C levels which is a sign of improved insulin sensitivity.  

An advantage of time-restricted eating versus other dietary interventions like reduced calorie intake is that it is very simple to perform.   To learn more about time-restricted eating (which is also referred to as “intermittent fasting”) check out this previous blogpost on this subject:  http://workoutanytime.blogspot.com/2020/06/the-benefits-of-intermittent-fasting.html

Strength Training for Heart Health!

 


New research published in Medicine and Science in Sports and Exercise showed that resistance training – even without doing any cardio – will strengthen the heart and help prevent a heart attack and stroke.

The study looked at data from 12,591 men and woman who came into the Cooper Clinic for at least two preventive health screenings between 1987 and 2006.

The researchers found that a little resistance training can go a long way!    The research showed that even one resistance training session per week cut peoples’ risk of heart disease and dying from a cardiovascular event by 40 – 70 percent – even if they did not get the recommended amount of cardiovascular exercise.

Bottom line – do NOT skip your cardio workouts but make sure you get at least one strength training session per week in!
