Nutrition Advisory Board Member Spotlight: Scott Sehnert, MS, RD, CSCS, CSSD

This month, Orgain is thrilled to feature advisory board member Scott Sehnert, MS, RD, CSCS, CSSD, who shares about his inspirational journey toward becoming a sports dietitian, and more. Scott is a Board-Certified Specialist in Sports Dietetics and Certified Strength and Conditioning Specialist with the National Strength and Conditioning Association. Named the Dallas Cowboys’ Director of Sports Performance leading into the 2016 season, Scott works closely with both athletic trainers and strength and conditioning coaches in developing player-specific nutrition and recovery plans. Learn more about Scott and Orgain’s other seven nutrition advisors here.

1. We would love to hear about your journey toward becoming an RDN.  Why did you decide to pursue this profession?

I started off at Ball State University as an exercise science major as I was on the football team and interested in becoming a strength and conditioning specialist.  When I “retired” from playing football and began coaching high school football and playing club lacrosse at Ball State, I was no longer in the varsity weight room and lost interest in the profession of strength and conditioning…for a period of time.  I remained interested in health and sports, and then read about an NFL player seeing a sports nutritionist in the off-season.  I thought, “health and sports,” that’s what I’ll do.  I Googled (there was Google then) “how to become a sports nutritionist,” and fortunately it directed me to become a Registered Dietitian.  Also, fortunately Ball State had a dietetics program.  Despite the director of the program telling me I’d never work in sports nutrition, I decided to move into that major.

2. What is the most rewarding part of the work you do?

Building relationships with players, coaches and staff.  I love helping with their overall health, but that’s just the gateway to build healthy relationships, which I ultimately enjoy.

3. What is one of the most frequently asked question that you receive from athletes and what are your recommendations?

“Isn’t there too much carbs in that?” Almost every time, the education turns to the fact that they utilize so many carbohydrates in the training and competition they go through that they have a need for a considerable amount of carbohydrate.

4. What are the greatest challenges and opportunities within sports nutrition?

Challenge – The challenge is often in athletic departments/clubs recognizing the difference between “sports nutrition personnel” and a sports nutrition program.  One is running around just getting food in the right places where the other is helping change behavior and culture around food.

5. What interested you in becoming a member of the Orgain Nutrition Advisory Board?

I value the story of Dr. Abraham.  We have a motto in our department, that we’re here to “serve and solve.”  Dr. Abraham saw a problem that needed to be solved and through that he is serving a huge community.

Science Based Brief

Demystifying Plant-Based Diets to Maximize Athletic Performance

Plant Based Athlete

The Olympic games are a chance to catch awe-inspiring, world class athletes in action. Both Olympic-level athletes and avid exercisers are driven to maximize achievement, and many top athletes follow a plant-based diet to improve recovery and performance. Plant-based diets are rich in whole grains, beans, legumes, nuts, seeds, fruits and vegetables, and they minimize but don’t always exclude animal products. This way of eating is popular due to benefits for health and the environment, and a well-planned, plant-based eating routine may offer a competitive advantage.

Benefits for Athletic Performance
While a plant-based diet is best known for its whole-body health benefits, this eating pattern may also provide direct improvements toward optimizing athletic performance including:

  • Building lean body mass and reducing excess body fat
    A plant-based diet leads to reductions in body fat due to increased energy expenditure and reduced calorie intake.1 The typical lower fat and higher fiber content of a plant-based diet can significantly reduce body fat. One of the proposed mechanisms of the advantages of a lower fat plant-based diet is increased energy expenditure after a meal, which has been suggested to be due to changes in mitochondrial activity. The number and activity of mitochondrial cells in the body is constantly changing, and diet influences these changes.2 In an examination of subjects eating a 50% fat diet, the biogenesis of mitochondrial cells was significantly reduced in just three days.3 High-fat diets are thought to disrupt cellular metabolism which reduces energy expenditure, while a plant-based diet with lower levels of fat has the opposite effect, increasing post-meal energy expenditure. The lower fat plant-based diet also typically has higher amounts of carbohydrate which requires more metabolic work to convert to body fat, favoring a reduction in body fat storage.2 Furthermore, research has also suggested that a high-protein, exclusively plant-based diet is no different from a protein matched mixed-diet in supporting muscle strength and mass accrual.

  • Increased VO2 max
    VO2 max is a measure of the maximum rate of oxygen consumption during increasing exercise intensity. An athlete with a higher VO2 max relative to body weight will outperform an athlete with a lower VO2 max due to the advantages this provides for endurance.2 When comparing subjects with type 2 diabetes following a conventional diet versus a plant-based diet with a calorie restriction (- 500 kcal/day), those following a plant-based diet, consisting mostly of whole plant foods with one serving of low-fat dairy daily, had a 12% increase in VO2 max. No advantages were observed in VO2 max for those following the conventional diet typically recommended for people with diabetes, which included a slightly lower carbohydrate content and slightly higher protein and fat content than the plant-based diet.4

  • Improvement in glycogen storage
    During moderate and high-intensity exercise, carbohydrate is the primary source of energy. Healthful carbohydrates such as grains, legumes and root vegetables are plentiful in plant-based diets. Carbohydrate intake is important to fuel activity before an event, and it also helps maximize liver and muscle glycogen stores to fuel long-term activity.2,5

  • Increased oxygenation of tissues
    A plant-based diet is typically low in saturated fat. This reduces plasma lipid concentrations which may lead to improvements in blood viscosity, or less resistance to blood flow, and improvements in arterial flexibility, endothelial function and oxygenation of tissues. The bloodstream carries oxygen and nutrients to tissues and removes metabolic waste products, and athletic activity depends on these processes.2

  • Less oxidative stress and inflammation
    Although exercise produces healthful changes in the body, it also produces free radicals as a normal function of the cell mitochondria and other cell responses from tissue damage. When the production of free radicals exceeds the body’s ability to neutralize them, this results in oxidative stress which can lead to muscle fatigue and impairments in athletic performance and recovery. A plant-based diet rich in antioxidant-rich fruits, vegetables and grains improves antioxidant activity as well as antioxidant enzyme production in the body.2 Intense exercise causes an inflammatory response in the body that may contribute to sore muscles, pain, reduced muscular performance and impaired recovery. A plant-based diet with low levels of saturated fat and more antioxidant-rich fruits, vegetables and grains is helpful in fighting inflammation.2,6

Protein from Plants
Both resistance and endurance training have important effects on skeletal muscles that impact the requirement of dietary protein for muscle protein synthesis, remodeling and repair. Exercise itself increases muscle protein synthesis, and post-exercise nutrition is an important part of optimizing skeletal muscle adaption.7 Plant-based whole foods can supply not only adequate protein but additional nutrients including vitamins, minerals and carbohydrates. A plant-forward diet contributes to post-exercise muscle protein synthesis as well as offering benefits for health, body composition and athletic performance.7,8 Short-term studies show that a well-planned, plant-based diet with adequate protein also supports bone density9 and strength.10

A variety of whole foods from a plant-based diet can adequately raise blood leucine concentrations, which is a branched chain amino acid (BCAA) and an indicator of muscle protein synthesis. The use of protein supplements is helpful to increase blood leucine concentration and vegetarian protein supplements that include a variety of plant-based protein sources can supply adequate leucine to promote muscle protein synthesis.5,11 Although leucine is an essential amino acid and blood levels of leucine are an indicator of muscle synthesis, a balanced intake of all essential amino acids is important to promote muscle synthesis.12

Athletes following a plant-based diet may have questions about processing of vegetarian sources of protein and whether this improves the availability of protein from these sources. Processes including fermenting and germinating of vegetarian foods improves nutrient profiles, which can be beneficial for the plant-based athlete in fighting oxidation. The evidence is unclear regarding the benefits of germination methods on improving availability of vegetarian protein sources for the body, with mixed results likely due to differences in germination testing conditions. Fermentation of plant proteins increases the digestibility of the protein possibly due to partial breakdown of complex protein into more soluble forms and partial predigestion by bacteria.13

Cardiovascular Health and Endurance Athletes
Endurance athletes may benefit from plant-based diets to help prevent atherosclerosis,2 which is more common in endurance athletes than sedentary adults. Although the mechanism is unclear, longstanding endurance activity is linked to a modest increase in calcified coronary plaques.14 In a small study comparing sedentary males with male runners who have completed at least one marathon yearly for 25 consecutive years, the runners had accelerated coronary plaque volume.15 Plant-based diets improve plasma lipid concentrations, blood glucose control, blood pressure, body weight and antioxidant activity, which not only helps prevent atherosclerosis but can also improve performance and recovery for endurance athletes.2

In a study comparing over 44,0000 vegetarian and nonvegetarian men and women, vegetarians were found to be 32% less likely to develop ischemic heart disease (IHD)16, which is narrowed heart arteries that can lead to a heart attack.17 The vegetarians had lower systolic blood pressure,16 which is an indication of how much pressure is exerted against artery walls as the heart beats.17 They also had a better lipid profile possibly due to lower BMI and consuming more healthy unsaturated fats and less saturated fats. The lower BMI rates among the vegetarians studied may be a factor in the lower systolic blood pressure, a 3.3 mm Hg reduction was found in the vegetarians, which could translate to an estimated 10% reduction in risk for IHD.16

Considerations for Athletes
Protein consumed immediately after exercise and evenly throughout the recovery period is beneficial to stimulate muscle protein synthesis and facilitate muscle repair.7,8 Ideally, it’s important to include protein within the first hour and at regular intervals over the 5 to 72-hour period following exercise to optimize skeletal muscle response. Since regular exercisers and athletes don’t typically have long breaks between exercise events, consuming protein-rich foods in meals and snacks is especially important. Exercise specific diet advice requires careful planning by a nutrition professional.8

U.S. and international sports nutrition experts recommended a minimum of 1.2 to 2.0 grams of protein per kg body weight per day for vegetarian athletes.5,12 Protein supplements are a convenient, reliable way to help meet these increased requirements. Liquid protein supplements are helpful since liquids are both convenient and not filling, making them easy to add to the diet.5,8 When protein is taken in combination with whole foods containing carbohydrate, this can help facilitate muscle glycogen resynthesis.8

Scott Sehnert, MS, RD, CSCS, CSSD, a sports dietitian, Director of Sports Performance for the Dallas Cowboys and member of Orgain’s Nutrition Advisory Board states, “There is a growing body of evidence showing that plant-based nutrition, when planned properly, can support muscle growth equally to nutrition from animal sources. Orgain Sport Protein is a way to support plant-based nutrition as its blend provides sufficient leucine to stimulate protein synthesis and muscle growth.”

“When working with a large number of athletes, you will find that you need a variety of products to meet their needs and wants. While whey continues to be a go-to when it comes to recovery protein, for one reason or another some athletes look for a plant-based product. Because of that I like to have Orgain Sport Protein Powder handy. It provides a robust amino acid profile for stimulating muscle protein synthesis, and because it is Certified Organic, I know they are following some of the strictest processing standards. The “cherry on top” is that it is the best tasting and mixing plant-based powder I’ve tried as well.”
