treadmill-heart-rate-200-300Finding the body’s target heart rate (THR) is essential for those interested in maximizing the effectiveness of their workouts and training programs and reducing the risk of overexertion.

The Simple Method For Calculating Your Target Heart Rate

There is an easy method for determining your THR: Start by subtracting your age from 220 (226 for women); this will provide your estimated maximum heart rate (MHR). Multiply your MHR by the percentages listed for the appropriate exercise zone from the list below.

  • Healthy Heart – For low-intensity exercises and warm ups. The THR for this zone is 50%-60% of the MHR.
  • Fitness – For more intense but generally low to moderate effort exercises. The THR for this zone is 60%-70% of the MHR.
  • Aerobic – This zone helps build endurance and increases the strength and size of your heart. It also improves your cardiovascular and respiratory system. The THR for this zone is 70%-80% of the MHR.
  • Anaerobic – For performance training. This zone increases the amount of oxygen you can consume during physical exertion. The THR for this zone is 80%-90% of the MHR.
  • Red Line – For maximum intensity exercises that burn the most calories. The THR for this zone is 90%-100% of the MHR. This level should only be attempted by those in excellent shape who have been cleared by a physician or qualified medical examiner.

So, for example, a 40-year-old woman who wishes to find her THR for a fitness zone program would use the following equation: (226 – 40) X 60% = 111 (low end) and (226 – 40) X 70% = 130 (high end). Therefore, as long as she maintains her heart rate between 111 beats per minute (bpm) and 130 bpm, the woman is at the proper target heart rate for maximum exercise efficiency and safety.

A More Accurate Method

A more accurate method for determining your THR is the Karvonen formula, but this requires that you determine your resting heart rate (RHR) and your heart rate reserve (HRR). Measure your resting pulse (your heart rate just as you wake up) three mornings in a row. Your RHR is the average of these three readings (add the readings and divide by three). Your HRR is your MHR minus your RHR. Once you have calculated your HRR, multiply it by the percentages for the zone you want to target for and add the RHR. The equations are as follows:

MHR = 220 (or 226 for women) – age (in years)
RHR = average resting heart rate (average of 3 readings)
HRR = MHR – RHR
THR = (HRR * target zone percentage) + RHR

So for our hypothetical 40-year-old woman targeting a fitness zone…

MHR = 226 – 40 = 186.
RHR = (64 + 62 + 63)/3 = 63
HRR = 186 – 63 = 123
THR = (123 * 60%) + 63 = 137 (for the low end) and (123 * 70%) + 63 = 149 (for the high end)

If you have any doubts or questions about the proper method for determining your THR, ask your chiropractor, physical therapist or doctor for help.

    Dr. Dubois, is one of these zones best for burning fat? Seems like a few years ago we were being encouraged to exercise in one of the less intense zones in order to burn more fat. Should we do that or simply try to burn the most calories we can during our workout? Thanks.

      Dear Teresa,
      To keep things simple, it is important to understand that during exercise your body gets energy from primarily two places: fat stores, or glycogen stores. Glycogen is stored carbohydrates in your muscles and liver, and fat in the fatty cells. At lower exercise intensity (50% max HR), more fat is burned relative to glycogen(50%Max HR=605fat/40% Glycogen, 75%max HR, 35%fat/65%glycogen and so on).

      Studies showed that for a 30 minutes low vs high intensity work out, the total calories burnt are 200 for a low intensity group, vs 400 for a high intensity group. But out of the 200 cal of the low intensity, 120 were from fat and 80 from glycogen, and out of 400 cal of the high intensity group, 140 were from fat, and 260 from glycogen.

      You can immediately see that increasing from 50 to 75% of the max HR only increase the fat mobilization by 20 cal, which is not very efficient. Furthermore, when somebody starts exercising and is not used to it, pushing them rapidly into the 75-80% MHR will have them crash early. They will stop the exercise before the 30 mins. and therefore end up burning even less fat.

      But as their fitness level increases, it is in my opinion a good idea to go into higher % of the MHR because of the following reason: If you exercise at a 50% MHR, when you stop it is the end of it. If you exercise at a higher level, there is a metabolic disturbance that burns calories after the workout is completed: it is the after burn effect (exercise speeds up the metabolism and keeps that accelerated rate going even after you’ve completed your routine. This “after-burn” effect can last from 15 minutes to 48 hours, depending on how hard you exercise).

      To conclude, there is no “one size fits all” way to look at it. But based on the science we have on hand, we want to try to exercise as hard as we can for as long as possible without hurting ourselves. But the work out must be increased gradually in time and intensity, and associated with a well organized recovery time to insure the capacity to burn fat for a long time.

      Probably a lot more than what you hoped for…but as you know very little is black or white.

      Have a great day,

      Pierre

What Is The Pectineus Muscle And Why Is It Important?

Spring Is In The Air

spring floridaI remember as a child we sang “Though April showers may come your way…they bring the flowers that bloom in May…”

Of course, here in Florida we are blessed with flowers all year, but there’s still a lovely feeling that happens in Spring.  It’s still cool enough most days to go out running, and the humidity is still low.  Traffic will soon be easing up as our friends from the north start their trek back home, and daylight savings time is giving us more time to get to the beach for sunset.  Lovely!

Fun Facts About Spring….

  • The earliest known use of the term “spring cleaning” was in 1857
  • The word “spring” has been used for the season since the 16th century
  • The first day of spring is called the vernal equinox
  • On the first day of spring, the sunrise and sunset are about 12 hours apart everywhere on earth
  • Spring fever isn’t just a saying. Experts say the body changes due to the temperature and can cause an upset in your health.
  • The actual start of spring varies from March 19th to the 21st, but it is commonly celebrated on the 21st.

Do you like to garden?  Now is the perfect time to get your gardens planted so you’ll have home grown veggies for the entire summer.  For me, it’s also a great time to do some spring cleaning and get the house in order before the summer closes all the windows and the air conditioning becomes our indoor relief.

But these activities can also cause a strain on muscles, so don’t forget to take care of yourself. If you put too much strain on muscles you haven’t used all winter, you can develop problems and need groin pain relief.

 

A Tiny Muscle Can Cause Groin Pain

groin pain relief pectineusLately I’ve had several clients come in because of groin pain that has their medical practitioners stumped.  Their symptoms are varied, but most complain that it feels like they hit their pubic bone with a rubber mallet.  Ouch!

One client loves to ride her horse, but the pain had prevented that for several weeks. Another was considering selling the motorcycle that she and her husband love because she just can’t sit on it anymore.

Several years ago, I had a male client tell me that he had this same pain and he was told it could be his prostrate causing the issue.  Fortunately, that wasn’t he problem at all.

The muscle that caused all these problems, and a lot more, is the Pectineus.

The Pectineus muscle originates on your pubic bone and inserts into the very top of your inner thigh bone (femur).

You can see the Pectineus and surrounding muscles more clearly by going to https://en.wikipedia.org/wiki/Pectineus_muscle

Most muscles have more than one function, and this is true for the Pectineus.  The function we’ll look at today is called adduction.  It brings your leg in toward midline.  If you think of a soccer player kicking the ball with the inside of his ankle, it was the Pectineus that helped draw his leg in so he could do the shot.

Each of my clients had pain while trying to bring their leg out so they could sit on their horse, or on their motorcycle.  The tight muscle was pulling on their pubic bone and causing a severe strain.

This muscle is easier to have someone else treat it for you because of its location but give it a try and see if you can locate & treat it yourself.

 

Groin Pain Relief

To reach the Pectineus, move the ball all the way up to the crease in your leg.  You can do the treatment with a ball, but because of the size of the muscle and its location, it’s easier to do it with your fingertips.

Sit as this athlete is sitting, and even bring your opposite leg up so your foot is flat on the floor.  For example, in this picture, the athlete would bring her right leg up so her right foot is on the floor, and then lean a bit further onto her left hip.  That opens up the area so she can reach a bit easier into the muscle while using her fingertips.

Press into the muscle, being careful to feel for a pulse, and moving if you feel one.  If the Pectineus is in spasm, you’ll know it immediately when you press on it.  If it’s not in spasm, you won’t be able to find it at all.

Remember to stay within your pain tolerance level, this isn’t a “no pain, no gain” situation.  Never go deeper than what feels tender, but not so much that you want to faint. Hold the pressure for 15 seconds. Then let up on the pressure, but keep your fingers in the same place.

Repeat this movement several times. Each time it will hurt less, and eventually it won’t hurt at all.  That’s when the muscle has completely released, and you will have relief from the pain.

It’s as simple as that!

Why stay in pain when it’s so easy to find the muscular source of the problem and eliminate it?
