Energy Systems

Energy is stored in a combination of:ATP – adenosine triphosphateCP – creatine phosphateCarbohydrates, fats & proteinsATP 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 recyclingADP combines with CP and recycles to ATPLittle CP is replaced in exercise as all is used to replace ATPCarbohydrates - Glycogen is the next fastest source after CP exhausted. When exercise begins the glycogen stored in the muscles is converted back into glucose.

Carbohydrates, fats & proteins

Carbohydrates - Glycogen is the next fastest source after CP exhausted. When exercise begins the glycogen stored in the muscles is converted back into glucose.

Storage Forms of Energy

ATP-CP System (Anaerobic alactacid)CP for first few seconds then glycogen. After approximately 20 seconds CP input is negligible.

Types of Training

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 100m 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 4,000m with short rests. Approximately 50-70% of mileage depending on

stage of season.

Endurance I - Basic

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 T30/T20 or current PB. Heart rate between 10-20 below maximum rate but this

method has more margin for error. Long sets up to 4,000m with rests between 10-45secs

depending on repeats. Approximately 20-40% of mileage – major sets use 50-70%

of stored glycogen.

Endurance II - Threshold

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

From T30/T20 or current PB. Heart rate between 10-20 below maximum rate

but this method has more margin for error. Long sets up to 4,000m with rests between 10-

45secs depending on repeats. Approximately 20-40% of mileage – major sets use

50-70% of stored glycogen.

Endurance II – Threshold

(cont)

Stresses the mix of energy systems as used in races, and improves VO2 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 2,000m 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.

Endurance III - Overload

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 VO2max, buffering capacity and both anaerobic and aerobic muscular endurance.

Sets from 200-1,500m.

Race Pace

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 – 1,200m (sprinters up tp 800m). Short swims in blocks around race distance with

long rests between repeats. Used sparingly and only extensively towards end

of competition period.

Sp1 - Lactate Tolerance

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 - 600m. Repeats of 25 -50m with long rests at near

maximum speed.

Sp2 - Lactate Production

To increase and optimise muscular power in the full stroke.

Maximum speed. Set length up to 400m Very short repeats – half lengths with long rests.

Sp3 - Power

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