ФИЛОСОФИЯ ТРЕНИРОВКИ: Зоны метаболической мощности, тренировочные нагрузки & другие категории
Андрей Воронцов: материалы для дискуссии с тренерами
Развитие методики тренировки на выносливость
A.V. Hill (1924-1927) предложил зоны интенсивности, основанные на анализе кривых мировых рекордов в легкой атлетике
Этот подход (5 зон мощности) был принят и в плавании: максимальные, субмаксимальные, большие, умеренные, легкие
F. Carlisle ввел ЧСС и ЭКГ в практику спортивной тренировки (1956-1961)
Doc J. Counsilman предложил тренировочные зоны, основанные на ЧСС и доминирующей энергосистемы: аэробная, аэробно-анаэробная, анаэробно-аэробная, анаэробно-гликолитическая, алактатная зоны (всего 5 зон интенсивности)
A. Mader & Lothar Kipke (1969) применили определение лактата, как критерий интенсивности
Дальнейшее введение многочисленных физиологических и биохимических критериев интенсивности упражнений

pH Blood Lactate mmol/l
Examples of Training Exercises
Aerobic-1 Zone of "aerobic threshold" with lipid metabolism. Continuos work of low intensity and long duration (30min - 2-3 hrs) The source of energy -- lipids (fat). Work is performed almost entirely by STO muscle fibres.
120-140 50-60% 7.42-7.40
0.9-2.0 30-min swim; 1 hour swim; 2,3,5,10 km swim or long interval sets - 40-100x100
Aerobic-2 Zone of anaerobic threshold - activation of FTO muscle fibres, but prevailing type of ATP replenishment still is aerobic. Sources of energy are lipids and glycogen.
140-160 60-70% 7.40-7.38
2.0-4.0 40-60x50 on 50", 3-5x800-1000 ; 15x300; 10x400; 30-40x100
Anaerobic Threhold
Zone of carbohydrate metabolism. Aerobic glycolysis provides 70-80% of total energy supply. Bypass product of aerobic glycolysis -- pyruvic acid is utilised in Kerbs’ cycle in mitochondria. Anaerobic glycolysis provides 25-15% of energy.
160-170` 70-90% 7.37-7.33
4.0-8.0 20-30x50 on 45-60 sec; 3-6x (6x100 on 1.20-1.30); 10-20x150-200; 6-10x400; 2-3x800-1000;
VO2 max Aerobic Power
Work is performed at the level of maxVO2. The share of anaerobic glycolysis in total energy supply is about 40-50%. The main source of energy is glycogen stored in muscles and liver. Significant production of lactic acid during exercise but aerobic energy supply still prevails. Dynamic work of "middle" duration, involving all muscle groups.

Snap-Shot test –3х200 м @ 3:30 (@4:00 or @4:30 for BR, Fly, IM ) Sub-maximal test does not demand
significant efforts May be performed as a part of warm
up or even swim down As TT may be taken time of 4th or 5th 200 in
step-test 7х200 m (3rd or 6th 200 if you like) Assessment: recent working capability +
HR response = readiness to intensive training
Correction of training velocities
Necessary additional information –individual maximal HR
Recorded Data: splits + total time in sec. & HR after each swim («POLAR»)
The software build a graph and calculate recommended training speed (times) for different zones of physiological intensity (correction of step-test data without taking blood samples)
Snap-Shot test –3х200 м @ 3:30 (@4:00 or @4:30 for BR, Fly, IM )
Aspects of aerobic training VO2 = 40-50% VO2max -no signs of Lactate accumulation
Lipids contribution = 99% At VO2 = 60% of VO2max contribution of lipids = 80%.
Aerobic glycolysis starts. La removal = 100% At VO2 = 70-75% of VO2max lactate level lactate
accumulation begins: La = 4 mmol/l At 80% of VO2max La=6-8 mmol/l, lipids contribution is
reduced 10% At 100% of VO2max La=9-12 mmol/l During the race VO2max achieves 95-100%, La = 15-18
mmol/lAt low intensities (50-70% of VO2 max) increases only
the number of mitochondriaAt higher aerobic intensities occurs an increase of both number of
mitochondria & concentration of aerobic enzymes
La removal: La-taxi development
1. Training at sub-AnT velocities (La 2.5-3.5 mmol/l) increases concentration of MCT-1 in heart muscle
2. Heart Rate Sets (Bob Treffine) – training at HR= 5-10 BBM – increases both MCT-1 & MCT-4 in skeletal muscles
La level = Lactate production – La removal
We know how the muscles and human body work
We learnt and memorized energy zones (HR zones, La zones…..)
By the means of trials & errors method and using scientific data we mastered how to periodize training
(when and how to train different energy systems and other motor abilities, how to pick them at proper time)
We must create a functional system “swimming” when all physiological systems works in accord with each other within the frame of efficient motor skill – swimming technique
We are dealing with a swimmer as “a whole thing”:Personality
Motor abilitiesFunctional power, capacity & efficiencyRational individual swimming technique
Not only “zone of physiological intensity” = “energy zones” that’s matter when planning training but specific demands of competitive event
Philosophy: do not train fatigue, rather prepare to swim competitive distance at target race pace with target SC, SR, SR:D/S ratio
Quality of training (training velocities) are of utmost importance
Way 1: to reduce training regiments in order to force a swimmer to swim faster at any cost (common approach in 1970-1980s) and resist fatigue (?)
Way 2: to increase the rest intervals to give a swimmer more time for recovery and let him/her swim at higher velocity while focusing on swimming technique and proper pacing: SC(SR), D/S, breathing patterns, glide distance (underwater kick, pull-outs), even or negative splits etc.

Training Categories
Race Pace training – training laps in a set are equal to the distance or its part and are performed at competitive or near-competitive pace:
INTENSITY NEAR VO2 max FOR DISTANCE & MIDDLE DISTANCE SWIMMERS
EXERCISES OF GLYCOLITIC & CR-PHOSPHATE ZONES FOR CPRINTERS
N x 100, 200, 300, 400, 500 м @ 800-1500 m PACEN х 50, 100, 150, 200 м @ 400 m paceN х 50, 100, 150 м со @ 200 m PACE
N х 25, 35, 40, 50, 60, 75 м @ 100 m PACE
Not only pace matter but stroke count, SR/SL ratio have to match to SC, SR, SL during competitive swimming –
should be established Target Pace, Target SC & SR/SL

PACE TRAINING
Front End Speed training – training exercises (1st 25 or 50 or 1st 100 m of the race) usually performed from the dive start @ target velocity of the beginning of the race with model SC, SR/SD :
N х 25, also Nх50, Nх100 («feet on the wall») @Target Pace of 50, 100 200 or 400 м
Elements of the race pace
Back-End Speed training – sets of the laps (“last” 25, 35, 50 or 100 м of a distance) usually performed from push off the wall or from “swim” start (“by the head”) @ TT of the 2nd half of the distance with T SC, T SR/SD: finish on hand touch
N х («last» 25, 50 or 100 m swam @ TT of the 2nd part of fraction of the 2nd part of the race (“last ½, ⅓, ¼, or ⅛ of the 50, 100, 200 или 400 m race)
Elements of the race pace
TOP-End Speed training – sets of the laps (“last” ⅓, ¼, or ⅛ m of a distance) usually from “swim” start (“by the head”) @ TT of the finishing race @ T SC, T SR/SD:
N х («last»50, 40, 35, 30, 25, 20, 15 or 100 m, swam @ TT of the corresponding fraction of the 2nd part of the race (“last ⅓, ¼, ¾ or ⅛ of the 50, 100, 200 or 400 m race)
Usually with breath-hold Stroke control is at utmost importance!!!

Relationships «La : Speed»Estimated Target Times
Charts of Target Times for training of sprinters – how to use?
The aim of charts’ use – to make training specific in relation to distance velocity, SR, D/S – i.e. to train specific motor patterns
For TT calculation we may use both predicted or recent results of swimmers
Swimmers usually aim to achieve TT while swimming training laps or distances usually not exceeding 60% of competitive distance (100 или 200 м)
Always use TT together with other criteria of competitive activity: SR, SC, D/S, distance under water after starts or turns, breathing patterns
Demand perfect swimming technique!!!
