Scope of Physical Exertion
Duration of a training unit and its frequency per week:
The optimum exercise range is 65-75% of the individual‘s cardiovascular performance over a longer
period.
Warm-Up
At the beginning of each training session, you should spend 3-5 minutes warming up with a slowly
increasing level of exertion to bring your cardiovascular system and your muscles to the right tempe-
rature.
Cool-Down
Just as important is the so-called „cool-down“. After each workout you should continue running slowly
for about 2-3 minutes. Initially, the exertion level for your further endurance training should basically be
increased by means of the scope of physical effort, e.g., training takes place 20 minutes daily instead of
10 minutes, or three times a week instead of twice a week. In addition to the individual planning of your
endurance training, you can also use the training programmes integrated into the treadmill‘s training
computer.

11.1 Training Form and Movement Execution
On the treadmill, various forms of training can be used -- from walking, to power walking, to sprinting.
The movement execution of walking, power walking, running, and sprinting is divided into four phases:
Phase Start End Notes / Motion Description
Front Swing
Phase
Support leg under
the body’s centre of
gravity
Touchdown of
the foot
Here the maximum knee stroke takes
place and serves mainly for the forward
swing of the leg. When the foot makes
contact with the ground, the lower extre-
mities are cushioned by a passive braking
movement within 10 - 20 ms.
Front Suppor-
ting Phase
Touchdown of the
foot
Vertical posture When the foot touches down, forces are
generated that represent 2-3 times the
weight of the body. It is therefore import-
ant to wear the right footwear to adequa-
tely absorb the shock impact and to ensu-
re a healthy pronation of the foot.
Back Suppor-
ting Phase
Vertical posture Propulsion with
the foot
In the final phase, the foot is stretched out
and propulsion takes place via the first
toe.
Back Swing

Propulsion with the

Bewegungsbeschreibung
Vordere Schwungphase Stützbein unter dem
Körperschwerpunkt Aufsetzen des Fußes
Hier findet der maximale Knie-
hub statt und dient hauptsäch-
lich dem Nachvornschwingen
des Beines. Beim Aufsetzen
des Fußes werden innerhalb
von 10-20ms die unteren
Extremitäten durch eine passi-
ve Abbremsbewegung
gedämpft
Vordere Stützphase Aufsetzen des Fußes Vertikale Körperhaltung Beim Aufsetzen des Fußes ent-
stehen Kräfte die das 2-3
fache des Körpergewichts aus-
machen. Es sollte daher
darauf geachtet werden das
passende Schuhwerk zu tra-
gen, um die aufkommenden
Kräfte adäquat zu absorbieren
und eine gesunde Pronation
des Fußes zu gewährleisten.
Hintere Stützphase Vertikale Körperhaltung Abstoßen des Fußes In der Endphase wird der Fuß
gestreckt und es findet ein
Abstoßen über den ersten Zeh
statt
