weight management for athletes

2010;298:E449–66. Wishnofsky’s static energy balance equation is still widely used in the research literature and given to athletes as a guide for weight loss [7, 30]. Developing a weight management plan is essential for everyone, including athletes that expend high amounts of energy in their sport. When these individuals want to lose weight, it is imperative that the risk of introducing disordered eating behaviors is minimized (Sundgot-Borgen & Torstveit, 2010). J. Those who are young and still growing but need to learn how to manage their eating behaviors to match energy needs. Rolls (1998). Exercising women with menstrual disturbances consume low energy dense foods and beverages. 2016 Mar;45(3):e87-90. 2011;378:826–37. Initially there would be a period of positive energy balance, where body weight would increase, resulting in an increase in energy expenditure that will eventually balance the increased energy intake. If an athlete needs to lose weight, working with a supportive health care team such as coach, sports medicine team, and sport dietitian will help ensure success. Those who are already lean and want to be leaner, while retaining lean tissue. [53] showed that obese women counseled to consume a low-ED diet (n = 35) for 1 year lost 20 % more weight (–7.9 kg) than those counseled to reduce fat intake only (n = 36; –6.4 kg). Changes in exercise strategies or training routines are not addressed, since coaches typically determine these for the athlete. Helms ER, Zinn C, Rowlands DS, et al. Other factors that can confound the assessment of energy balance in an athlete are the total amount of non-sport-related activities (e.g., walking and biking as modes of transportation, yoga, dancing, etc.) In general, most athletes and active individuals who want to lose weight fall into two categories: Those who are overfat or obese based on body-fat levels. For some athletes, the elimination of ED beverages from their diet may help them achieve their weight loss goals without making any other dietary changes. Weight Management for Athletes and Active Individuals: A Brief Review. Flegal KM, Carroll MD, Ogden CL, et al. Ultimately, the goal is to identify a weight that promotes good health and is ‘reasonable’ to achieve and maintain for most of the year, while keeping the ‘diet for weight loss’ periods short. The supplement was guest edited by Lawrence L. Spriet, who attended a meeting of the GSSI expert panel (XP) in March 2014 and received honoraria from the GSSI for his participation in the meeting. Flegal (2010). Burke, S.M. Kam, G.F. Maddalozzo, and M.M. CBD for Athletes, Weight Lifters and Weight Management. [42] at the Pennington Biomedical Research Center (PBRC) (http://www.pbrc.edu/research-and-faculty/calculators/weight-loss-predictor/). Thus, for these athletes, weight loss could improve performance and prevent the development of serious chronic diseases. Ogden, C.L., M.D. During this time, they were randomly assigned to either a control (1 g/protein/kg; n = 10) or treatment group (2.3 g/protein/kg; n = 10) [34]. One mathematical model has been developed by Hall et al. Yet, this simple concept is more complicated than that and can be difficult to implement. Int J Sport Nutr Exerc Metab. Ann. Some athletes believe that cutting weight will improve their athletic performance, but dramatic and fast weight loss often has the opposite effect. Join a weight management program. Int J Sport Nutr Exerc Metab. Chow, Y.C. Washington, D.C.: The National Academies Press; 2005. Finally, following a lower-ED diet could help the athlete maintain their weight loss. Weight man… Sports Nutrition: Effective Weight Management for Athletes- Guest Post. Stensel D. Exercise, appetite and appetite-regulating hormones: implications for food intake and weight control. Weight management is an important part of weight-classified sports, including wrestling. When dieting for weight loss, active individuals also want to preserve lean tissue, which means that energy restriction cannot be too severe or lean tissue is lost. Bell, E.A., V.H. They found that when they fed three different levels of ED diets, the women ate a similar amount and weight of food; however, on the lowest low-ED diet condition, participants consumed 30 % less energy than the high-ED diet. Nattiv A, Loucks A, Manore M, et al. Am. For these athletes, sweetened beverages (e.g., sport drinks) should be limited to what is needed for hydration and fueling when participating in exercise and sport. Weight Management in Athletes Lecture 1. CAS  Rolls BJ. https://www.topendsports.com/nutrition/weight-restrictions.htm Rice, K. Sharpe, I. Mujika, D. Jenkins, and A.G. Hahn (2005). There is less reliance on reducing portion size and counting calories. However, we now know that weight loss changes over time with the same level of negative energy imbalance [31]. Thomas DM, Bouchard C, Church T, et al. A high-protein diet induces sustained reductions in appetite, ad libitum caloric intake, and body weight despite compensatory changes in diurnal plasma leptin and ghrelin concentrations. Giel, and S. Zipfel (2013). Thus, the individual would eventually achieve energy balance and become weight stable at a higher body weight, which might be a realistic weight gain of ~6 lbs (~2.7 kg). Stensel, D. (2010). American College of Sports Medicine Position Stand. Article  However, this approach, combined with an intense endurance and strength-training program, can actually increase metabolic adaptations that slow weight loss and diminish the additive effects of these two factors on weight loss [37]. Weight management is difficult for most individuals, as indicated by the high numbers of overweight and obese individuals in the USA and around the world [1]. A systematic review of dietary protein during caloric restriction in resistance trained lean athletes: a case for higher intakes. [44] showed that slower, more reasonable weight loss in athletes (~0.7 % loss of body weight/week) helped preserve lean tissue while improving strength gains compared with more severe weight loss (1.4 % weight loss/week). J. Clin. Appetite-regulatory hormone responses on the day following a prolonged bout of moderate-intensity exercise. They assume that changing either side of the equation by 3,500 kcal will result in a pound (lb) (7,700 kcal for 1 kg) of weight gained or lost, without considering how changing energy intake or expenditure changes the energy balance equation. Int J Sport Nutr Exerc Metab. Weight management is a concern which the majority of athletes will experience at some stage of their career. This approach reduces hunger and increases adherence to the weight loss diet plan. Thus, numerous factors work together to influence each side of the energy balance equation, which ultimately determines body weight. Unfortunately, this epidemic is not limited to adults but also to children in both globally and Cyprus. (2015) Manore. ACSM's Health Fit. 2010. http://www.cdc.gov/nchs/fastats/overwt.htm. Google Scholar. However, to maintain this larger body size, the individual would need to continue to eat these additional kcals each day. Weight management for athletes and active individuals is unique because of their high daily energy expenditure; thus, the emphasis is usually placed on changing the diet side of the energy balance equation. Manore, M.M., N.L. (2009). Join a weight management program. Donnelly, J.E., S.N. Whether you want to lose six pounds, 60 pounds, or more, my weight management program is designed to help you achieve lasting weight-loss results without fad diets. If a child/youth athlete is overweight or obese, they may have a significant amount of weight to lose to be considered competitive and, thus, be pressured by themselves and others to lose weight. Fad diets promise quick weight loss through extreme restriction, often by consuming a minimal amount of calories and eliminating certain foods. 67: 412-420. However, during periods of weight loss or gain, weight is not stable. For example, Borchers et al. Some athletes believe that cutting weight will improve their athletic performance, but dramatic and fast weight loss often has the opposite effect. (2009). In my research I read Weight Management for Athletes and Active Individuals by Melinda M Manore. Specifically, we surveyed 698 male athletes regarding frequency and circumstances of team weigh-ins, weight management behaviors, weight intentions, caloric intake, and guidance received for healthfully managing weight and eating. Sci. These dietary factors can also alter the thermic effect of food [18] and the type of substrates oxidized during exercise [15, 19, 20]. Thus, the post-exercise dietary routine needs to include fluids for rehydration, carbohydrate in the form of low-energy dense foods (e.g., whole fruits and vegetables, whole grains) to replenish glycogen, and high-quality low-fat protein for building and repair of lean tissue. J. Meengs (2006). Bodyweight exercises are a great way to learn how to maintain a neutral spine by keeping the core braced and taking their body through some type of movement patte… Swinburn and Ravussin [28] gave a classic example to illustrate the fallacy of this concept. Conversely, high-intensity exercise can blunt appetite-regulating hormones, which could reduce energy intake (Stensel, 2010). 2005;82:41–8. If an athlete does not meet their energy demand their performance is likely to suffer. Each high school wrestling program has been mandated by the National Federation of State High School Associations to determine an appropriate weight classification for each individual wrestler. 41: 709-731. Jakicic, M.M. Although not typically obese or over fat, elite and recreational athletes can also struggle with body-weight and image issues. There has been heavy research into young athletes developing eating disorders, especially females, from following diet plans in order to meet their desired weight. Fortunately, it is easy to consume a low-ED, high-nutrient dense breakfast by including low-fat, high-quality protein (e.g., low-fat dairy or soy products, egg whites, lean meats) and high-fiber, carbohydrate-rich foods (e.g., whole grains, fruits). When dieting for weight loss, active individuals also want to preserve lean tissue, which means that energy restriction cannot be too severe or lean tissue is lost. 2015;141:23–31. As cannabidiol (CBD) popularity as an alternative therapy increases, its ability to bring the body back into balance from the inside out is getting more attention. Spriet (2011). Thus, this approach should be avoided [7, 10, 13, 36]. Yet these individuals may want to lose weight and fat to improve sport performance, make the team in a weight class sport, or achieve an aesthetically pleasing body shape. According to cross-sectional cohort studies using questionnaires (e.g. The following section highlights evidence-based diet and lifestyle recommendations for athletes and active individuals who are interested in losing weight (e.g., fat mass), maintaining lean tissue, and/or preventing weight regain. If an athlete needs to lose weight, working with a supportive team (e.g., coach, sports medicine team, and sport dietitian) will help ensure success. WEIGHT MANAGEMENT FOR ATHLETES. Energy content of weight loss: kinetic features during voluntary caloric restriction. CAS  In addition, they are extremely stressful for the athlete and cannot be sustained for long periods. For example, Carlsohn et al. 2010;303:242–9. Believe in yourself! Thompson, J., M. Manore, and J. Skinner (1993). Available at: https://www.washingtonpost.com/archive/sports/1997/12/18/weight-loss-methods-probed-after-3-college-wrestlers-die/3dcb7763-8491-4b8f-bac6-6991b2ef64b2/?utm_term=.d880ab19ab01. Metabolic syndrome and insulin resistance in Division 1 collegiate football players. Table 1 demonstrates the difference in time needed for a designated weight loss change for an overweight rower using the Hall et al. They fed three different levels of energy dense diets, where the women ate a similar amount and weight of food. OBJECTIVES Discuss athletes concerns regarding weight loss & weight gain Provide recommendations for healthful weight loss & weight gain strategies for athletes Describe body composition concerns Describe physiological mechanisms that effect body weight and appetite … Article  weight to lose to be considered competitive and, thus, be pressured by themselves and others to lose weight. Eng. Those who are overweight and need to lose body fat but also want to retain lean tissue. 2010;68:375–88. The following section highlights evidence-based diet behaviors that can help athletes and active individuals reduce body fat while maintaining lean tissue and prevention of weight regain. Am J Clin Nutr. Mountjoy M, Sundgot-Borgen J, Burke L, et al. Swinburn (2011). Find a friend or family member who can listen and relate to what you are going through. Dietary protein, weight loss, and weight maintenance. PubMed  Update May 9, 2008: I weigh 144 now, so I have lost 4 pounds in three months. Finally, at least 30% of children in the United States are overweight/obese (Ogden et al., 2010) and many obese children may participate in sports. PubMed  Finally, it can be difficult to manage safe weight loss in athletes who need to meet a designated weight on competition day, such as lightweight rowers, jockeys, or wrestlers. Overall the diet is lower in fat and reduces or eliminates beverages containing kcal, especially sweetened beverages and alcohol. Int. Callahan, K.E. It may be more typical for the majority of the energy and protein to be consumed in a large meal at the end of the day. Weight management approaches used in active children need to consider their growth and energy needs and place the focus on healthy eating and staying physically active, not on caloric restriction. Some athletes require building of body mass, muscle and power, while others need strength and flexibility on a small frame. Time to correctly predict the amount of weight loss with dieting. Unfortunately, when athletes attempt to lose weight, they often use unhealthy weight-loss practices such as fasting or skipping meals, severe energy restriction, and dehydration [13, 14]. Increased risk of poor nutrient intakes, including essential nutrients, due to limited food intake. This will improve their ability to design individualized and realistic weight-management programs. 303: 242-249. Extreme dieting or calorie restriction makes needed nutrients, such as carbohydrates, sparse. Finally, severe energy restriction during times of high exercise has a number of other negative performance and health consequences for the athletes, as follows [10, 15]: Decreased sport performance effects due to decreased muscle strength, glycogen stores, concentration, coordination and training responses, and increased irritability. The relationship between dietary energy density and energy intake. Scand. For the athlete with excess body fat, weight loss could improve sport performance and reduce the risk of chronic disease. Am. For many athletes, the majority of the energy and protein comes in a large meal at the end of the day. Sundgot-Borgen J, Garthe I. To preserve lean tissue during periods of energy restriction, protein intake (g/kg) needs to remain high (1.2-1.7 g/kg/d). J. Clin. A low-ED diet is high in whole fruits, vegetables, and grains, and incorporates low-fat dairy, legumes/beans, and lean meats. Weight loss can be difficult and may change body composition unfavorably; thus, managing weight during the off-season is especially important to avoid performance-damaging rapid weight loss during competition. Int. Am. Med. Therefore, athletes restricting their calories to lose weight should eat 0.8–1.2 grams of protein per pound of body weight (1.8–2.7 grams per kg) per day (2, 3, 18). Second, the concept of dynamic energy balance is reviewed, including two mathematical models developed to improve weight-loss predictions based on changes in diet and exercise. Increased risk of dehydration, especially if the diet is ketogenic. Under these conditions, energy balance is a dynamic process (Galgani & Ravussin, 2008), since changing the energy intake side also impacts the energy expenditure side. Overall, reducing the ED of the diet is more effective at lowering energy intake than is reducing portion size, without affecting hunger, fullness, or enjoyment of the food. Energy needs and weight management for gymnasts. Weight Management for Endurance Athletes By Carol Scheible February 16, 2008 General. Phillips SM. While some athletes may seek to lose weight to improve performance, others have trouble maintaining or gaining weight because of a high metabolism or heavy training schedule. 2nd Ed. [32], as they found that when overweight (BMI ~28 kg/m2) sedentary men and women restricted energy intake by 25 %, the energy deficit required for weight loss was ~2200 kcal/lb during the first 4 weeks of the diet. These models are now available on the Internet. Maybe according to their Coaches and the program they followed in their high school weight room they were strong, but... they were missing the boat, BIG time. 1. Those who are already lean, but desire additional body fat loss. Aspects of disordered eating continuum in elite high-intensity sports. Nutr. OBJECTIVES Discuss athletes concerns regarding weight loss & weight gain Provide recommendations for healthful weight loss & weight gain strategies for athletes Describe body composition concerns Describe physiological mechanisms that effect body weight and appetite … 93: 525-534. Eating More and losing weight with a low energy dense diet. Reductions in portion size and energy density of foods are additive and lead to sustained decreases in energy intake. Sci,. Borchers JR, Clem KL, Habash DL, et al. The energy density of a diet or a food is determined by measuring the amount of energy (kcal) for a given amount (g) of food (Table 1). Eat a hearty breakfast. 2004;62:S82–97. Math. Regarding to an athlete, weight management is an increasingly integral part, as consuming the right kind of food can lead them in success or failure. Thus, individuals will lose weight differently on the same weight loss diet, even if no exercise is part of the weight loss plan. JAMA. In helping these individuals achieve their weight and sport goals, it is imperative that the risk of introducing restrictive and disordered eating behaviors is minimized, especially in those athletes participating in lean build sports [7, 9, 10]. 82: 236S-241S. Sports Medicine. Get Started. Hawley JA, Burke LM. Adv Nutr. This type of diet contributes to weight loss and good health in three ways: Research shows that a low-energy density eating plan is effective at reducing energy intake, facilitating weight loss, preventing weight regain, and helping to maintain satiety in well-controlled feeding studies and in free-living conditions (Ello-Martin et al., 2005; Rolls, 2009). Sci. Thus, reducing portion sizes and energy density dramatically reduced energy intake, but just reducing the energy density of the foods consumed reduced energy intake more than reducing portion sizes. Sports Exerc. Every triathlete wants to be leaner, faster, and more successful. PubMed  Stokley, and T.M. Sport Nutrition for Health and Performance. Exerc. Why do individuals not lose more weight from an exercise intervention at a defined dose? We are offering a “Weight Management & Sports Nutrition Certification” course. Information herein is intended for professional audiences, including scientists, coaches, medical professionals, athletic trainers, nutritionists, dietitians and other sports health professionals who have a fundamental understanding of human physiology. Exercise-trained men and women: role of exercise and diet on appetite and energy intake. Currently, no published research has reported using a low-ED diet for weight loss in athletes; however, researchers have observed that female athletes with exercise-associated menstrual dysfunction who consume low-ED diets have inadequate energy intake to match energy expenditure [54, 55]. 5 Ways CBD Can Benefit Athletic Performance. Prevalence and trends in obesity among US adults, 1999–2008. Hagobian TA, Braun B. 2011;21:97–104. Appropriate physical activity intervention strategies for weight loss and prevention of weight regain for adults. Fad diets promise quick weight loss through extreme restriction, often by consuming a minimal amount of calories and eliminating certain foods. Melinda Manore, PhD, also attended the GSSI XP meeting in March 2014 and received honoraria from the GSSI, a division of PepsiCo, Inc., for her meeting participation and the writing of this manuscript. Ann Rev Nutr. Overall, relatively few male athletes reported undergoing mandatory team weigh-ins (21.8%). The longer and more often you are engaged, the better long-term success. Purnell (2005). Wang, S.L. PubMed Central  An athlete who is constantly dieting or repeatedly gaining and losing weight may be trying to achieve an unrealistic body weight, which may place them at risk for disordered eating. Increased protein intake reduces lean body mass loss during weight loss in athletes. New fat free mass—fat mass model for use in physiological energy balance equations. Nutr. 37: 860-866. This point was demonstrated by Heymsfield et al. Part of Springer Nature. Using a 75-kg man, they demonstrated how weight would change if this individual consumed an extra 100 kcal/day (~420 kJ) for 40 years [28]. Ello-Martin, J.A., J.H. Appl Physiol Nutr Metab. "Nutritional modulation of training-induced skeletal muscle adaptations" J. Appl. This high-fiber, high-water, low-fat diet means an individual can consume a greater volume of food for an overall lower energy intake and still feel satiated. When dieting for weight loss, active individuals also want to preserve lean tissue, which means that energy restriction cannot be too severe or lean tissue is lost.
