About Dr. Kelleher: Dr. Kelleher is an orthopedic surgeon who has practiced for over 20 years. She has a particular interest in musculoskeletal health for athletes. An athlete herself, Dr. Kelleher ran track in college and began masters track in 2012. She has achieved her athletic goals using MOVE! principles. Below Dr. Kelleher offers brief notes related to nutrition, injury, rehabilitation and training.
Fueling For Competition
Recently MOVE! hosted a talk on fueling and supplements with speakers by Dr. Inez Kelleher, orthopedic surgeon and silver medalist in the National Senior Games, and 2016 Olympic Triathlete Joe Maloy. Topics covered included foods/macronutrients for competition, Vitamins, and supplements including caffeine. The next note will focus on Joe’s thoughts on caffeine.
Regarding the question of whether or not to take supplements, Dr. Kelleher stressed that food is the best choice for nutrition – better than supplements. They, however, can help provide nutrient deficiencies not obtained in your diet. Magnesium is one trace mineral, for example, that is difficult to obtain enough of in your typical diet. (400 mg. is the current daily requirement. Magnesium is found in dark, leafy greens, seeds, nuts, whole grains, yogurt, and bananas.)
Dr. Kelleher discussed some supplements, such as Beta Alanine, that have been known to help with performance – with intensive anaerobic bursts lasting from one to four minutes. She stressed that if you do consider supplements, they should be used with moderation and careful thought. Critical to choice of supplements is to research the quality of the company that produces it. Some companies (such as Thorne) are known to control resources to be sure contaminants.
Dr. Kelleher reviewed the main functions of macronutrients and their recommended relative consumption. Carbohydrates supply energy, protein builds structure for building and repairing muscles, bones, organs, hormones, and enzymes, and fats provide energy and building blocks for natural steroid hormones including estrogen, testosterone and cortisol. Recommended ratios of consumption in a daily diet include 40 – 55% carbohydrates, 10-15% protein, and 30% fats.
How much protein should athletes ingest? As a general rule, 1-1.5gm per kg body weight or .45-.68 mg/lb divided in three to four servings per day is best. As an example, a woman weighing 125 pounds should consume from 56 to 85 grams of protein. Athletes should shoot for the higher end of that range.
Regarding timing of meals, as the link to the piece “Fuel for Training and Competition” (see below) indicates, a rule of thumb to have a meal one to three hours before your event. The article also suggests samples of pre-competition meals or snacks. Inez noted that it’s best to avoid eating high fat before training or competition to avoid feeling full and bloated.
During competition in events longer than a few hours, fuel with carbohydrates every 30 to 60 minutes. Fresh fruit, dry cereal, peanut butter and jelly sandwiches, crackers and fruit yogurt are good sources of carbohydrates.
“Fuel for Training and Competition” includes recommendations of timing of specific foods to eat if you are entered in a meet with several heats or events scheduled with breaks throughout the day. If you, for example, have a meet with one- to three-hour breaks, what do you eat? What do you eat afterwards?
After a workout or competition, nutrients should be replaced within 30 minutes, chocolate milk being an excellent replacement. Milk is 90% water. It offers a macronutrient ratio of 4:1 carbohydrates to protein. Carbohydrates refuel muscles after exercise. The calcium, vitamin D, and phosphorus build and muscle recovery. Milk’s potassium wards off muscle cramping. The B vitamins help convert food to energy.
The next note will feature Joe Maloy’s comments on caffeine for competition.
Is It Plantar Fasciitis?
Plantar fasciitis, the most common cause of heel pain in adults in the United States, is associated with runners who overtrain, weight-bearing professions, poor footwear, decreased ankle motion, and obesity. Plantar fasciitis is caused by micro trauma and excessive strain to the plantar fascia, the stiff tissue that runs from the bottom of the heel to the base of the toes. This tissue supports the arch in the foot, particularly during toe off while walking and running.
You probably have plantar fasciitis if you have heel pain with your first steps in the morning or after sitting and resting. It can get worse throughout the day after prolonged standing.The pain will temporarily improve with rest, ice, and anti-inflammatory medicines. The good news is that 85 to 95% of those plagued with plantar fasciitis will respond well to non-surgical treatments.
If you have plantar fasciitis avoid barefoot activities and wear shoes with good support (cowboy boots work great). Plantar fascia specific stretches, foot muscle strengthening, night splints, heel cushions, and shoe inserts improve plantar fasciitis pain. Cross training to avoid excessive strain during healing is important.
For those with symptoms lasting longer than six months cortisone injections are considered. Surgery may be required for the 5 to 10% that do not get better. Some people will have x-rays which show a bone spur. This is not the cause of the pain. Anatomic studies have shown the spur is not located in the plantar fascia but it is associated with a small muscle in the foot. - dr. k
Relax in a Sauna and Improve Athletic Performance?
Saunas have long been used for several health benefits including high blood pressure control, immune system boost, body detoxification and post workout relaxation. Research findings support sauna therapy in post workout recovery, muscle growth and improved athletic endurance. In a recent study, running to exhaustion time improved 23-30% after sauna for three weeks, twice a week for 30 min. The researchers attributed this change to increased blood flow to the heart and increased plasma volume (natural blood doping?!). Since 1989 scientists have known Growth Hormone levels increase after sauna, supporting muscle growth and repair.
Lactic acid and uric acid from your muscles are found in sweat after workouts. Sweating in the sauna also helps your body remove toxic substances like heavy metals (mercury, lead, arsenic, cadmium) and organic pollutants such as BPA and pesticides. Some of these toxins are thought to be associated with chronic disease such as autoimmune disease, diabetes, Parkinson’s disease to name a few.
There are three main types of saunas, wet, dry, and infrared. The infrared sauna is considered the best, dry and steam also work the temperature is not as easy to control. Use caution when first starting saunas. Drink plenty of water, start slowly (3-4 min) and work up to 15-30 minutes. Always ask your doctor first if sauna therapy is all right for you.
Find a sauna near you; relax and sweat your way to improved performance! - dr. k
Don't Forget Fish Oil
Fats – the right kind of fats – are important in our diet. Like vitamins, Omega6 and Omega3 fatty acids (FA) are fats that are essential and our body cannot make them.
Omega6 oils are plentiful in our diet -- maybe too plentiful. Omega 3 is not. Omega 3 oils are important for all our cells' membranes, making them pliable, and fluid. Dry flakey skin may indicate a deficiency in your diet.
Omega 3 plays an important role in decreasing inflammation in our joints, muscles, and tendons. Studies also show a decrease in coronary artery disease and cardiovascular events in people taking fish oil supplements, as well as a decrease in Alzheimer's, and an increase in longevity.
Omega3 FA can be found in walnuts, flax seed,chia seeds, grass fed beef, certain eggs, tuna, trout, oysters, and sardines, to name a few foods. Typically, these are not consumed on a regular basis, so fish oil supplements can be used. They usually have two omega3 oils, DHA and EPA. They should total (DHA +EPA) 700 to 1000mg.
The USRDA has recommended a dietary intake of 1600mg for men and 1100mg for women. Some experts feel we need up to 4000mg per day. So consider taking 1100 to 4000mg depending on which guideline you want to follow. There is a prescription also available. For that, check with your doctor.
After a few weeks of Omega 3s, your joints may feel better especially if you have discomfort secondary to inflammation in your body (asthma, allergies, eczema). Also, if you have bumps on the back of your arms (keratosis pilaris) they may go away, your skin texture and dryness overall will improve.

Know About Magnesium
Why magnesium? It is a necessary element for many reactions in the body, including ALL ATP production. ATP supplies the energy for our muscles. Seventy percent of the magnesium is found in our bones and is important in influencing bone formation. The remaining 30% circulates in our body.
Over our lifetime a decrease in magnesium can affect the possibility of developing diseases such as hypertension, cardiovascular disease, diabetes, osteoporosis and migraines.
Daily requirements for women range from 310 to 320 mg. daily. The standard American diets tend to be deficient in magnesium. Medications that can prevent magnesium absorption are proton pump inhibitors (commonly used for reflux disease) and diuretics .
Some foods that are good sources of magnesium include spinach, quinoa, almonds, soy beans, halibut, and tuna. Ask your doctor for more advice.
And -- BTW -- magnesium is the prime ingredient in epsom salts. Soak in it and you will soothe your muscles.
