WHAT IS FNP? EXPLAIN ALL ITS PHASES AND GIVE AN EXAMPLE FOR THE QUADRICEPS AND ANOTHER FOR HAMSTRINGS
FNP (PNF in English) means PROPIOCEPTIVE.NEUROMUSCULAR.FACILITATIONand
it is a stretching technique used to improve muscles elasticity and has
been shown to have a positive effect on active and passive ranges of
motions.
4 Phases are mainly differentiated:
1.A first passive stretching during 20 seconds
2.Followed by an isometric contraction of 8 seconds
3.A rest of approximately 5 seconds
4.And ending with a new passive stretching for 20 seconds EXAMPLES: Hamstrings:FNP of hamstrings consists of sitting on the floor and trying to touch your feet at the same time your partner is pushing you. Quadriceps:FNP of quadriceps
consists on lying down on the floor while our partner pushes our back with his arm and takes our leg to our waist.
EXPLAIN THE GENERAL SYNDROME OF ADAPTATION AND ALL ITS PHASES. GIVE AN EXAMPLE
The General Syndrome of Adaptation (GAS) is a three stages procces that
describes the physiological changes the body goes through when is under
stress.
The three stages in which it is divided are:
1. Alarm reaction Stage: The Alarm
Reaction Stage refers to the initial symptoms the body experiences when
is under stress. This natural reaction prepares you to either flee or
protect yourself in dangerous situations
2. Resistance stage:After the
initial shock of a stressful event, the body begins to repair itself. It
releases a lower amount of cortisol, and your heart rate and blood
pressure begin to normalize.
3.Exhaustion:This stage is the
result of prolonged or chronic stress. Struggling with stress for long
periods can drain your physical, emotional and mental resources to the
point where your body no longer has strenght to fight stress.
EXAMPLE:
- Failing an important exam
-Losing a close familiar
-Feeling lonely
EXPLAIN THE THRESHOLD LAW BY ARNOLD SCHULT. ILLUSTRATE WITH AN EXAMPLE.
This theory starts from the existence of a minimum threshold or stimulus
necessary for somebody to produce, improve or adapt in the organism
It is a very personal issue. There is also a maximum tolerance or point
from which only the fatigue and overtraining. According to this
law,adaptation occurs as a result of physical efforts proposed in a
consistent and appropiate manner so that the organism assimilates them
progressively.
1. In the first case is very far from the threshold so neither the training is given nor improvements
2. In the second case at best if you could give the training if the job
was repeated several times, but what would be achieved more that nothing
would be fatigue and decreased performance.
3. The third case would be the ideal, in the musce, technical, organic, improvements are achieved
4. In the fourth case is not achieved any improvement and leads overtraining and fatigue.
EXAMPLE:
WHAT IS THE TRAINING LOAD AND WHAT ARE ITS COMPONENTS? EXPLAIN THEM AND GIVE AN EXAMPLE OF EACH ONE
In sports training load is a central phase through which performance of a sportsman is improved.
Every sports training consists of physical exercises which cause
fatigue. Fatigue is directly a product of training load which helps in
the process of adaptation.
Therefore training load and fatigue are important for any kind of sportsman performance.
COMPONENTS:
Volume:Training volume is the amount of work done.
EXAMPLE: If I go to the gym for 1 hour, the volume 1 hour
Intensity:Training intensity is how hard you train.
EXAMPLE: If I do a Farleck the Intensity is the type of Farleck (Low, Medium, High) Frequency:Training frequency is how often you perform certain move, practice certain exercise or train certain muscle.
EXAMPLE: If I go running 2 times per week the frequency is 2 times per week
Density:Training density is the relation between work and each pause.
EXAMPLE: Reduce fatigue having breaks.
Duration:Is the repetitivity of the stimulus
EXAMPLE: If I do 20 push-ups the duration is 20.
EXPLAIN THE PRINCIPLES OF TRAINING ACCORDING TO THE CLASSIFICATION OF OLIVER (1985) AND ZINTL (1991)
The principles of sports training are
defined as general rules are applied as the training of any sports discipline,
that is, the aspects that occur by the simple fact of applying physical stress
to the body.
Oliver establishes the following categories to classify the different principles: - Principles related to the stimulation of physical conditioning. This
says that the traininig stimulus must overcome a certain threshold of
intensity to be able to initiate an adaptive reaction, to have an effect
in the training. - Principles related to the systems to which said stimulus is directed. A
stimulus is any change that is capable of producing a response from the
organism. The receptors are very specialiszed structures capable of
perceiving the stimuli and converting them into nervous impulses. There
are two groups. Internal and external. - Principles related to the response to said stimulus. The
stimuli respond to reactions of the environment or their own, and are
subject to the nature of the action that precede it becoming a
situational chain in which the process is repeated, being: A stimulus
that precedes a perception and this causes an action, where the cycle
returns and repeats itself because the action is the stimulus that
precedes another perception that originates another action.
Zintl encompasses its proposed principles in three groups: - Those who initiate the adaptation. The
adaptation to physical effort in the development of basic physical
abilities. Following the definition of Alvarez del villar, the
adaptation is the ability of living beings to maintain a constant
balance of their functions before the stimuli that affect them.
- Those that guarantee adaptation. In
a complete macrocycle, we will have mesocycles or microcycles in which
we need to perform very strong stimuli, but we must know how to control
stages and guide our training correctly bases on our objetives. I repeat
we can't always train heavy, since, our central nervous system would
not support it, and our muscles either. - Those who exercise a specific control of adaptation. Those
who exercise specific control over adaptation. In order to make
adaptation processes specific for each person, it is necessary to follow
some principles, for example the individualization. Training loads
should be specifically oriented towards the personal and individual
person: ( age, sex, motor skills)
A party animal: a person who enjoys going to parties. Party Pooper: a person who spoils or ruins a party because of not taking part of the activity or by leavimg early. Dance the night away: to have a great or an enjoyable time. Bouncer: a person who is emploed at a bar. Party foul:something socially unaceptable done in a social gathering. Socially unaceptable:something that is looked down upon by the older generations. Social butterfly:someone who is very social and easy going. Wallflower:someone shy. Party crasher: someone that invites himself in a party he isn't even invited to. Wet Blanket:someone who ruin other people's good times.
