Stott<\/span><\/strong><\/p>\n<p style=\"text-align: center;\"><strong><br \/>\nIn the first of two parts, Swimming World explores the concept of energy systems and how coaches can use them to maximize athlete development and performance.<\/strong><\/p>\n<p>In the world of athletic training\u2014nay any field of endeavor\u2014there are varying degrees of sophistication and understanding.<\/p>\n<p>In aquatics, that may range from beginning summer league coaches to the likes of Ph.D.\/Olympic mentors, sport scientists and beyond.<br \/>\nA successful swim coach doesn\u2019t have to have an advanced degree in kinesiology. However, a basic understanding of energy systems and how they affect athletic training can certainly help.<\/p>\n<p><span style=\"color: #e0ac0d;\"><strong>THE SCIENCE<\/strong><\/span><br \/>\nLet\u2019s begin with metabolism, the process of storing and releasing the energy. There are three main metabolic pathways to recycle energy in muscle cells during exercise, notes Genadijus Sokolovas, High Performance Director at USA Pentathlon and senior physiologist at Global Sport Technology.<\/p>\n<p>They are non-aerobic (creatine phosphate), anaerobic (anaerobic glycolysis) and aerobic. Energy for body usage is stored in different forms and pathways, and is used to convert the three forms into accessible energy for the athlete (or anybody) to perform work.<\/p>\n<p>\u201cThere are no borders to energy pathways in a body,\u201d says Sokolovas. \u201cAt any given time, several pathways may be engaged in energy production. However, dominance of an energy source depends on the duration and intensity of the exercise,\u201d he says. \u201cTypically, workload is broken into several energy zones based on that duration and training intensity. Energy zones allow athletes and coaches to develop a specific pathway of energy recycling to quantify, track and plan the physiological adaptations desired for their specific event.\u201d<\/p>\n<p>At one time, USA Swimming identified seven energy zones. These were categorized as Recovery (Rec), Endurance 1 (EN1), Endurance 2 (EN2), Endurance 3 (EN3), Sprint 1 (SP1), Sprint 2 (SP2) and Sprint 3 (SP3). The organization has since reduced the number to five, a number that correlates with those utilized by European coaches. In practicality, the number may be reduced to three: aerobic, anaerobic threshold and high performance endurance with subsets (anaerobic race pace and high velocity overload) found under the high performance category.<\/p>\n<p>Over the years, various coaches and organizations have altered the categories and subsets to suit their training modes and preferences. Grandfather to the codification of the zone system is Jon Urbanchek who, at the University of Michigan, introduced energy category color-coding for ease of understanding and communication with his athletes. Urbanchek\u2019s original chart consisted of seven categories, which he has since modified to five for ease in training.<\/p>\n<p><strong><span style=\"color: #e0ac0d;\">ENTERING THE ZONE<\/span><\/strong><br \/>\nSo how does one effectively measure the utilization of each energy system to perform well? The simple answer is heart rate and time measurement. While heart rate monitors may be the most accurate means, not everyone has a watch with that measuring capability or desire to strap a monitor across the chest. A more convenient and universally accepted method is to place two fingers on the carotid artery, count the number of heart beats (noting the first beat as zero and moving the thumb away from the artery) for 10 seconds and multiply by six.<\/p>\n<p>For that measurement to have meaning, an athlete needs to determine his\/her maximum heart rate for each training zone. Training zones are calculated by using BBM (beats below maximum). For example, a swimmer with a maximum heart rate of 210 beats per minute working in the A1 (low-intensity aerobic zone, 60-50 beats below maximum) would need to be functioning at 150 beats per minute.<\/p>\n<p>Another way to calculate each training zone is to use swim and rest times or personal best times +5 seconds or 10 seconds. That method requires a coach to have precise knowledge of swimmer workout and race histories in order to have them training in the proper energy zones.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.swimmingworldmagazine.com\/issues\/2021\/swimming-world-magazine-june-2021-issue-pdf-only\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"color: #0000ff;\"><strong>To read more about energy systems, workout routines for establishing training values and their applications,<br \/>\nClick here to download the full June 2021 Issue of <em>Swimming World<\/em> Magazine<\/strong><\/span><\/a><\/p>\n<p style=\"text-align: center;\">\n<p style=\"text-align: center;\"><em>Michael J.
