Health and Physical Activity
Physical
activity has been shown to be important to some programmes of health
promotion
as well as within the Traditional Chinese Medicine (TCM) model. Here
we will focus
on activity and its benefits for a variety of health areas.
The Nature of Physical Activity - Biddle & Mutrie (2001) delineate
physical activity
as sport and exercise, and the research from each can help in
application to the other.
Psychologists are involved in both areas as exercise (a leisure activity)
and sports psychology (psychological factors
involved in sports).
Physical fitness involves physiological functioning as well as physical attributes that enable fitness.
It may involve
cardiovascular, endurance, muscular endurance,
muscular strength, body
composition and flexibility.
Sport is hard to define, is sometime difficult to distinguish from games,
recreation, play, & leisure activity.
It can be judged to
include "activities involving powers and skills,
competition and strategy,
and/or personal gain" (Wann, 1997, cited in Poole et al., p. 198).
Physical Activity and the Five Components of Health
Greenberg & Pargman
(1989) identify five aspects of health that are important to keep in balance.
The full complement of these spheres of health is crucial.
They are: mental,
physical, emotional,
social and spiritual.
Poole et al give the
case study of Peter who had a heart attack then went through
depression before
recovering physically. They report that his mental, social spiritual
and
emotional spheres improved along with improvments in his physical sphere.
A this is an example of the general pleasure of active leisure rather than passive leisure (Csikszentmihalyi, 1997).
Rates of Physical activity
While it has been
suggested that each person gets at least 30 min of moderate exercise
per day,
Stats Canada reports that in 1996-97 57% of Canadians over the age of 15
exercise
three or more times per week, while 22% reported less than once per
week or never.
British Columbians (30%) reported the highest levels of regular exercise in contrast with the rest of Canada at 20%
Other estimates suggest that 50% of those who started a structured exercise programme has discontinued within six months.
King et al. (1999)
report a comparison of Canadian and European adolescents
indicating that there
was a decline for Canadians between 1989 & 1998 on
exercising twice or more per
week along with an increase in those who watch
four or more hours of TV
per day.
Marks et al. (2015) discuss the range of activities that people may engage in that have potential health benefits.
They examine physical activity as part of daily work routines,
transit to and from work as well as planned recreational physical activity.
Social class, age, gender, culture and a number of other factors play a role in the amount
and types of physical activity that people engage in and examine participation rates F10.1
as well as reasons for engaging in it F10.2 across two studies in 2009 and 2013.
The Five Forms of Physical Activity
Isometric - involves the contraction of muscle groups against immovable
objects
- tension without movement. Works on strength only.
Isotonic - involves repeated and limited movements (like weight lifting
or calisthenics)
working on smaller muscle groups. Works on strength and
endurance as does isokinetic.
Isokinetic - involves full range movements in weighted or sophisticated machinery that adjusts load to position.
Anaerobic - involves low oxygen because the intense short-term
physical activity
requires more oxygen than is taken in during this period.
Aerobic - involves increased oxygen consumption during extended
period of time.
The increased oxygen can lead to health benefits in
cardiovascular, pulmonary and muscular.
Psychological Benefits of Physical Activity
Generally speaking exercise makes people feel good and exercise psychology
studies this,
along with Sports Psychology it is one of the growing areas
of the discipline.
Exercise has been associated with changes in mental states
ands well-being
as well as sense of self, however roadblocks, such as challenges
in assessing change,
appear which lead to problems of adherence.
Physical activity and sense of self
Folkins & Syme (1981)
have reviewed studies on self and exercise,
they found that most studies were
poorly designed, however some changes in self-concept
were revealed.
(Note:
methodologically the "self-Concept" is very messy with numerous
operational definitions. E.g. the text reports
numerous scales for this, p. 211. )
What really does all of this mean if the
various concepts and measurements of
self are quite at odds with each other?
Self Efficacy - One standard of the
self literature is Bandura's "self-efficacy"
or "people's judgment of their
capabilities to organize and execute courses of
action required to attain
designated types of performances" Bandura, 1986, cited in Poole et al. , 2005).
Similar to
'confidence' insofar as it involves the "affirmation of performance capabilities"
(Poole, et
al, p.204) that may elevate performance beyond average skill level.
Challenge-Skills
balance is what is require, particularly when one's confidence wanes.
The
important component is the beliefs in the application of the skills to the
situation.
Sometimes performance
reaches a 'mystical' state of transcendence or
"flow" (Csikszentmihalyi, 1997)
where a sense of
effortlessness and stopping of time, pain, & distractions.
E.g. Roger
Bannister & John Landry breaking the four-minute mile at Empire Stadium
in
Vancouver, 1954. (See Bandura, 1989 & Csikszentmihalyi).
According to Bandura
(1989) there are four important components to efficacy:
Performance
Accomplishments - involve the actual performances that lead
to success or
failure. Generally speaking, success will increase self-efficacy.
Vicarious Experience
- observing others and gaining a sense of efficacy based
on one's
understanding or own abilities with respect to those observed in others.
Verbal Persuasion - is used to persuade oneself or others about abilities and expected levels of performance.
Emotional Arousal - any given level or arousal or emotional state will have an impact
on self-assessment of efficacy. Too much or too little arousal may be
debilitating,
techniques like relaxation may be used to adjust it.
Physical activity and cognitive functioning
Research on the impact
of physical activity on mental abilities is unclear.
Etiner et al. (1997) report
that exercise and fitness may have a small positive impact
on cognitive
abilities, likely more so for chronic exercise, not acute.
Physical activity and mood
Anxiety
- research suggests that exercise can have an ameliorative effect on anxiety,
reducing it or serving as a distraction from the source of anxiety.
Effect may
be present both during and following exercise.
Depression
- research suggests that non-clinical depression may be reduced with
exercise,
acute or chronic, but server depression is not affected. It has also
been found the
clinically depressed individuals have lower levels of physical
fitness.
Psychological impact of physical activity suggests optimism and positive
attitudes are associated with higher levels of fitness.
Physical Benefits of Physical Activity
The impact of physical
activity on CHD has been shown in a Harvard Alumni study
to be positive where men who are physically
active have a 25% lower morbidity rate
for any cause and a 36% lowered chance of
death from CHD.
A sedentary lifestyle is described alongside of smoking and hypertension as a risk factor.
These benefits also
appear to be present in combating the likelihood of stroke and cancer,
where
physical activity serves as a buffer against stress.
Adherence to Physical activity
One of the most
important issues one must face in remaining physically active is non-adherence
to a programme of activity, as suggested by Estabrooks (2000,) 50% of people
drop out
of exercise programmes within six weeks.
Because of the
difficulty, transient pain, boredom or other such reasons,
exercise is not
always pleasant or fun.
Further, the positive benefits usually take time to arrive and be felt.
Zifferblatt (1975)
suggests that adherence is related to the visibility of cues
as to why one is
following the exercise program.
Various models brought forward in the text are not clear as they predict or impact physical activity.
Others such as
Kirschenbaum (1998) have suggested encouraging sport to make exercise
more fun
and gain better adherence.
Psychological Factors Affecting Performance in Exercise and Sport
There are two principle areas of concern in sports psychology 1) performance enhancement, 2) clinical issues.
Performance enhancement
involves acquiring psychological skills & methods
for attaining top performance. Arousal or attention control are common,
relaxation,
goal setting, and imagery.
Relaxation skills
enable one to reduce anxiety and focus attention.
PMR is
one of several techniques, involves a systematic focusing of attention on
different muscle groups. This provides a relaxation response that makes
good use
of breathing and muscle control.
Self-talk - pertains to what athletes
say to themselves around performance.
Analysis here can reveal cognitive
distortions, irrational thoughts, as well as positive
thought patterns. Self-confidence can be built or shattered by self-talk.
Albert Ellis promoted rational emotive behavioural therapy (REBT)
which works to eliminate irrational thinking such as:
absolute thinking (all or none),
overgeneralisation, & catastrophisation.
He also suggests that those who avoid
exercise
have low tolerance for frustration and often fear of failing.
Imagery - is used to promote positive states of mind and clean execution in performance.
internal - involves first-person active internal perspective.
The psychoneuromuscular theory suggests that this type of imagery
stimulates the neuromuscular pathways.
external imagery - involves third-person, passive, external perspective.
Goal setting - is an important aspect of sports psychology where different styles of orientation have different goals.
Ego-orientation
focuses on success and failure while task orientation
focuses on task mastery and satisfaction arising from a sense of competence.
outcome goals - concerned with the results of a performance
performance goals - relative to one's own goals where success
might be evident in
light of relative performance.
process goals - places emphasis on specific aspects of the performance
Physical activity and injury
This tends to be more clinical where attitudes and goals are concerned as part of rehabilitation.
Tai Chi & Chi Kong- are ways of moving energy through the body.
Dr Zhu reports that Tai Chi is considered to be a treatment for ill people in Beijing and here.
He reports many
benefits from it ranging from: improved blood and lymph fluid circulation,
massage of the lung and stomach cavities, increasing circulation through heart
and major arteries.
Tai Chi tones muscles and increases circulation, elasticity and
resilience of lung tissue, increasing O2 capacity,
speeds up metabolism,
increasing good cholesterol, strengthen immune system, prevents stiff joints
and
injured connective tissue, reduced osteoporosis.
Smooth round movements increase blood and qi circulation and strengthens the meridian systems.
Along with stress reduction it also develops social, ethical and spiritual skills.
For greatest benefit, slow down, more exercise from slow movements.
