stress
"We should recognise that stress is
not the stimulus but Homeostasis is the physiological process by which the body’s internal systems are kept within strict operational parameters. Blood pressure, body temperature and blood acidity levels are changed by variations in external conditions. For example, during strenuous activity there is a build up of waste products and rise in body temperature. Some of the waste, such as gas by-products, can be secreted by sweat glands. The evaporation of sweat from the surface on the skin has a cooling effect and lowers body temperature. If we become dehydrated and are unable to sweat, skin temperature increases rapidly and may feel prickly. This can become serious if liquid is not taken to allow a return to an acceptable temperature. Stress
is another factor that affects internal systems. How an athlete handles
stress is fundamental to performance. The belief that stress was harmful to performance led to the
use of methods to reduce anxiety, such as hypnosis
and
progressive relaxation. However the research behind
this practice has since been discredited. We do require a degree of
anxiety to perform. Stress activates nervous and endocrine responses to
prepare the body for physical activities even when this is not the most
appropriate response. In response to stress the hormones cortisol and
adrenaline are
released to prepare for ‘fight’ or ‘flight’. These hormones
increase functions such as breathing, the heart rate, sugar metabolism
and
muscle readiness. In short bursts it is a valid response to a perceived
threat. However if the stress response is
sustained over long periods it does have implications to our health. The
stress hormones effectively shut down systems not immediately required
for the fight or flight reaction such as the immune system. It
is important to be aware of our response to stress. It is possible to
use the stress response to
our advantage. We should recognise that stress is not the stimulus -
it is our reaction to it. We can choose not to respond to a stimulus
and prevent or modify the stress response. This is the essence of this
technique. We are learning to meet a stimulus and deal with it
appropriately. It is better to respond (use reason) rather than to react
(rely on habit). Loosing our temper is a good example of not
dealing well with a stimulus. Our
ancestors’ survival mechanism
may
be detrimental for the office worker when under stress, but still
appropriate for the demands of competitive sport. Relaxation methods
have a role to play after an
event when it may be necessary to halt the release of stress hormones
into the system. However, we must ensure that relax does not mean
collapse. The usual positions adopted for ‘relaxation’ often involve
total loss of appropriate muscle tone thus impeding bodily functions
such as breathing. Before
competing, techniques to lower anxiety can go too far and reduce our
readiness for the event. Experiments with medical patients undergoing
surgery found those who were too relaxed before the operation, took
longer to recover. If the amount of adrenaline
is
too low before the trauma, there is a greater shock to the unprepared
system. Relaxation techniques can achieve the opposite to the desired
affect. Our structure requires tension to utilise gravitational forces
in order to move and function. A poised athlete will have the necessary
tension to enable good movement, without the need to artificially ‘let
go’. The impact on performance is unique to each athlete with some performing better with high levels of anxiety while others flourish with relatively low levels (known as Individual Zones of Optimal Functioning (IZOF) - Hanin (1978,1986,1997)). If a stressful situation creates an attitude that is going to stiffen the muscles (body armouring) and prevent free movement, the body’s preparation for fight or flight is undermined. The athlete who can learn to inhibit a detrimental response to the situation is ideally prepared for competition - a heightened state of readiness, combined with poise. The first step to take is to ensure we do not stiffen our necks as the first reaction to a situation we perceive as stressful.
