Hertford SC WHY WHAT WHEN Energy Systems Anaerobic

Hertford SC WHY? WHAT? WHEN?

Energy Systems Anaerobic Alactacid ATP-CP Sp 3 Anaerobic (lactic) No Oxygen Sp 1 and 2 Aerobic With Oxygen End I, III and Race pace

Energy Systems Anaerobic Alactacid – (ATP-CP) Aerobic - (oxygen) Anaerobic -(without oxygen, lactic) Assume a 100 m race: ½ length Anaerobic Alactacid – Sp 3 3 lengths Aerobic – End I, III and Race Pace ½ length Anearobic (lactic) – Sp 1 and 2

Storage Forms of Energy is stored in a combination of: ATP – adenosine triphosphate CP – creatine phosphate Carbohydrates, fats & proteins ATP is only energy for muscular contraction. All others used to recycle ATP after use. ADP – adenosine diphosphate remains after ATP used. CP is the most rapid source of energy for ATP recycling ADP combines with CP and recycles to ATP Little CP is replaced in exercise as all is used to replace ATP Carbohydrates - Glycogen is the next fastest source after CP exhausted. When exercise begins the glycogen stored in the muscles is converted back into glucose.

Types of Training Aerobic (with oxygen) End I – Basic Endurance (about 70%) End II – Threshold Endurance (between 75 -85%) End III – Overload Endurance (about 90% plus) Race Pace (Race Speed) Anaerobic (without oxygen) Sp 1 - Lactate Tolerance (Max speed, no pacing) Sp 2 - Lactate Production (As fast as possible) Sp 3 - Power (Max speed)

Endurance I - Basic n n n n To develop aerobic endurance and to reinforce skills. To improve and maintain ability to train at higher speeds. About 70% and quite comfortable. Using a scale of 1 -20, a perceived effort between 12 and 14 is usually indicative of basic endurance training speed. Add between 2 -6 secs per 100 m to each swimmer’s threshold training pace. Heart rate between 30 -60 below maximum rate but this method has more margin for error. Long sets up to 4, 000 m with short rests. Approximately 50 -70% of mileage depending on stage of season.

Endurance II - Threshold n n n n n Overloads the aerobic system to maximum, and raises the anaerobic threshold. Improves the aerobic capacity of both FT and ST fibres. Maximum improvement of the aerobic system used in races. Between 75% - 85% and quite hard. Using a scale of 1 -20 at a perceived effort between 15 and 17 is usually indicative of threshold endurance training speed. From T 30/T 20 or current PB. Heart rate between 10 -20 below maximum rate but this method has more margin for error. Long sets up to 4, 000 m with rests between 10 -45 secs depending on repeats. Approximately 20 -40% of mileage – major sets use 50 -70% of stored glycogen.

Endurance II - Threshold n n n Overloads the aerobic system to maximum, and raises the anaerobic threshold. Improves the aerobic capacity of both FT and ST fibres. Maximum improvement of the aerobic system used in races. Between 75% - 85% and quite hard. Using a scale of 1 -20 at a perceived effort between 15 and 17 is usually indicative of threshold endurance training speed.

Endurance II – Threshold (cont) n n From T 30/T 20 or current PB. Heart rate between 10 -20 below maximum rate but this method has more margin for error. Long sets up to 4, 000 m with rests between 10 -45 secs depending on repeats. Approximately 20 -40% of mileage – major sets use 5070% of stored glycogen.

Endurance III - Overload n n n n Stresses the mix of energy systems as used in races, and improves VO 2 max. About 90% and very hard. Using a scale of 1 -20 at a perceived effort between 18 and 20 is usually indicative of overload training speed. Deduct between 2 -3 secs per 100 from threshold speed. Heart rate at maximum rate but this method has more margin for error. Set length up to 2, 000 m on main stroke with long rests – 30 secs to 2 mins depending on repeat distances. Up to 15% of mileage. Not when glycogen levels are low.

Race Pace n n n Improves the interaction of aerobic and anaerobic metabolic processes so that the energy for swimming at race pace is supplied faster and more economically. Improves the ability to sense and maintain race pace in competition. Improves ability to swim with the most efficient combination of stroke rate and length during competition. Improves the motivation and confidence of athletes in their ability to maintain a particular race pace in competition. Increases VO 2 max, buffering capacity and both anaerobic and aerobic muscular endurance. Sets from 200 -1, 500 m.

Sp 1 - Lactate Tolerance n n n n Enables swimmers to ‘hang on’ during races and maintain technique. Increases buffering capacity from working to non-working fibres and improves psychological tolerance of pain. Maximum speed from the start, no pacing. Very, very hard. Sets from 300 – 1, 200 m (sprinters up tp 800 m). Short swims in blocks around race distance with long rests between repeats. Used sparingly and only extensively towards end of competition period.

Sp 2 - Lactate Production n n n Increases the rate of anaerobic metabolism, producing lactic acid faster. Increases the speed of the final sprint in races. Bring races “home” faster. Increases muscular power and buffering. As fast as possible. Sets from 300 - 600 m. Repeats of 25 -50 m with long rests at near maximum speed.

Sp 3 - Power n n To increase and optimise muscular power in the full stroke. Maximum speed. Set length up to 400 m Very short repeats – half lengths with long rests.

Periodisation The process of planning training in order to produce high levels of performance at designated times.

Periodisation Hertford operate a two cycle periodisation. First cycle Hertfordshire County Championships in March. Second cycle – Hertford Club Championships in June.

Periodisation Each cycle comprises of macro and micro cycles within each major cycle. Main stages of each major cycle are: General Endurance Specific Endurance Competition/Taper
