Exercise for Younger Skin

July 20th, 2014

A new study shows that endurance training can reverse skin aging in people who start exercising later in life.  Volunteers aged 65 or older responded to exercise with skin composition very similar to 20- to 40- year olds.

As we age, changes occur within the layers of our skin.  After age 40, the outer layer of the epidermis begins to thicken, getting drier, denser and flakier.  The layer of skin just beneath begins to thin, losing cells and elasticity, making it appear more translucent and less firm.

As recently reported in the New York Times, researchers at McMaster University in Ontario conducted a study to see whether such changes are inevitable. The surprising results showed that at the start of the study the volunteers, age 65 or older, had normal skin for their age.  However at the end of a three month program of 30 minutes of moderate intensity jogging or cycling twice a week, their skin samples compared to those of much younger people.

In order to understand how exercise causes these changes, the researchers further checked for alterations in levels of substances created by the working muscles.  Called myokines, these substances are known to jump start changes in cells far from the muscles themselves. They found that the volunteers had almost 50 percent more myokines after exercising than at the start of the study.  It's unlikely that any pill, cream or injection will ever compare to the skin benefits of a workout!

10 Ways to Avoid Running Injuries

June 14th, 2014

Are you after a runner's high, a cardio tune-up or calorie burn? Whatever your motivation, early summer is an ideal season for running outside when you can breathe in fresh air, soak up Vitamin D from the sun, and enjoy green space. 

As millions of people take to city parks, country trails and high school tracks running injuries abound.  Not surprisingly, knee related injuries account for 25-50% of all lower extremity injuries (as reported in IDEA Fitness Journal, June 2014).  The foot, ankle, lower leg, hip and low back are also vulnerable. 

To keep you in the running, you must take steps to avoid injury from the most common causes.

1)         Do not increase your weekly mileage rapidly.  Make gradual changes.

2)         After a lay-off, take your time returning to your normal mileage.

3)         Avoid continuous high mileage. Risk increases meaningfully at 40 or more miles/week. 

4)         Intersperse some low-impact cross training like cycling and swimming.  Running 12 months without a break from training increases risk of injury.

5)         Alternate hard training days with lighter workouts.

6)         Steer clear of an abrupt change in running surface (grass, woodland trails, cinders, synthetic track, treadmill, concrete, etc.).

7)         Avoid running on uneven surfaces.  Most grassland, for example, is uneven and can cause problems for runners with unstable ankles.  At the beach, the tilt of sand at waters edge puts uneven stresses on the body.

8)         Change your running shoes every 350-550 miles, depending on your running style, body weight and surface.  Inadequate or worn-out footwear lacks stability and shock absorption.       

9)         If you have a history of previous injuries, learn to recognize the onset of the injury and control it.  Novice runners have higher rates of injury than seasoned runners because of this.

10)       Stay away from busy streets (for obvious reasons!)

Spring is the Season for Hip Fractures

April 23rd, 2014

New research reveals that most hip fractures occur in the spring in women over the age of 55.  Falls are the leading cause of these fractures in post-menopausal women, emphasizing the need for counseling to reduce the risk of falling both inside and outside the home.

As published In the current issue of the National Osteoporosis Foundation Report (April 2014), a group of researchers examined fracture data from 60,000 post-menopausal women from the US, Canada, Australia and seven European countries.  They found that only hip fractures showed a seasonal variation, with the majority occurring in the spring.  The main cause was falls resulting from slipping or tripping, both inside (52%) and outside (48%) the home.

One contributing factor could be lower levels of Vitamin D due to reduced exposure to sunlight over the winter which manifest in spring, however this was not studied. In addition to adequate Vitamin D, we need enough calcium to mineralize the bones.  Due to conflicting results of several major studies regarding calcium supplementation, experts recommend that the safest and most effective source of calcium is found in food choices, not supplements, and that exercise is key to bone health, specifically weight bearing and strength training exercise.

For more on the calcium controversy and types of exercise beneficial to the bones, please refer to this previous blog post.

Sculpt Your Arms in One Easy Move!

April 15th, 2014

Looking for the most efficient way to get tank top arms in a hurry?  Here it is:  The classic push up firms your chest, sculpts your shoulders and defines the triceps in the back of your upper arms, all in one easy move.  And even better, you can do this version at the kitchen sink while you're waiting for your coffee or tea.

The diagonal push up is a simply elegant exercise that activates these three muscles of the upper body as well as your core.  With your body on an angle, you need to assume a plank position, using your abdominals and back muscles to stabilize the torso.  The position of your arms determines which muscle you target.  Begin with one set of 10-15 reps of each position; build up to 2 sets.

To target the chest and firm the muscles under your bust line, position your arms 3-4 inches wider than your shoulders.  As you lower your chest toward the counter, bend your elbows out to the sides to 90 degrees (think of making a "box" with your arms).

To focus on your shoulders, move your arms in closer, placing your hands directly under your shoulders. As you lower your chest, bend your elbows straight back so they come in close to your sides.

For the triceps, move your hands in even closer, so that you can make a triangle with your index fingers and thumbs.  Now when you bend your elbows, they will flare out to the sides, making a diamond shape as you lower your chest to the counter.

Burn Calories with Winter Workouts!

December 9th, 2013

Expand your horizons beyond the gym this winter. Take your workout in the great outdoors to tone up, burn calories and stay strong. Redbook Magazine shares three of my favorite winter activities here.

  • Ice skating is a great family activity that you can pursue together, challenging your balance while working inner and outer thighs, glutes and ankles. An average woman (145 pounds) will burn 230 calories in 30 minutes.
  • Cross country skiing is the front runner for all-around aerobic benefits. It's a more complete workout than running or biking because it involves the upper body as well as the legs. The average woman will burn 260 calories in a half hour.
  • Snow shoeing is also a high calorie burn, like cross country skiing. It's more strenuous than walking or running at the same speed.  Adding poles makes it a full-body exercise as you engage the upper body.

Appropriate clothing and gear are essential to keep you safe and comfortable. Wear layers. While you’re moving you may get quite warm, but when you stop you can really feel the wind chill

Winter workouts keep you glowing! Here are a few of the health and fitness benefits of exercising outdoors:

  • Exposure to fresh air and natural light – soak up some Vitamin D.
  • Helps fight seasonal depression.
  • Manage holiday weight gain (the average weight gain is 3-5# during holiday season).
  • Maintain cardio fitness, strength, balance and coordination
  • Core strength is integral to all activities – full-body strength training will improve performance in all.
