Abstract: The associations between physical
activity, coronary risk-index and burnout, with specific focus on the role of
physical activity on the coronary risk-burnout relationship, were studied.
Altogether 833 white South African male executives were evaluated by a
self-report physical activity index, coronary risk index and burnout index
questionnaire. The high- (≥1000kcal.week-1) and moderate
active (151-999kcal.week-1) executives reported statistically significant
less (p≤0.05) burnout in comparison with their low active
(≤150kcal.week-1) colleagues. Moderate and high physical
activity levels were statistically related (p≤0.05) to a reduction in the
coronary risk-index. Similarly, burnout had a strong statistically significant
influence (p≤0.05) on the development of coronary heart disease. Finally,
physical activity portrayed a statistically significant (p≤0.05)
reduction in the coronary risk-index within low, moderate and high burnout
executives, but failed to influence the burnout-coronary risk relationship
between the different burnout groups. It is concluded that although physical
activity does not influence the burnout-coronary risk relationship between
different burnout groups significantly, it does seem to have a beneficial
effect on the reduction of the coronary risk-index within different burnout
groups.
An assessment of the physical fitness and coronary heart
disease risk factors of white females in the Zululand area that attend health
and fitness clubs
Coetsee,
Marius F.
Abstract: Health and fitness clubs play an
important role in addressing the causes of hypokinetic diseases and coronary
heart disease (CHD). In order to be well prepared, service providers should be
aware of the health and fitness profiles of their clients when they join their
clubs. In the current study 243 white female subjects between ages 13 to 70
years were assessed, the results analysed for risk factors and the findings
compared with existing norms in literature. This study found that 19.8% of
subjects smoked > 10 cigarettes per day which is a cause for concern.
Although this is lower than the general female population of Durban the current
subjects joined a health and fitness centre and could thus be regarded as
health conscious. Before joining almost half (49.4%) of the subjects were
inactive. The incidence of hypertension (systolic >140 mmHg and/or diastolic
> 90 mmHg) as a risk factor for (CHD) among 16.5% of subjects was relatively
low when compared to that reported for females in Durban. Cholesterol levels
were also lower than the average for Durban females because 28.6% of the
subjects were found to be borderline (5.2-6.2 mmol.l-1) and 16.7% to
be of a high risk (>6.2 mmol.l-1). When using BMI, 19.3% of
subjects were > 37.3 kg.m-2 and therefore in a high-risk group
for CHD. Multiple risk factor analysis revealed that 42.0% of subjects
displayed two or more risk factors for CHD while 12.0% had three or more and
2.0% had four or more.
Physical exercise and psychological wellness in health
club members: a comparative and longitudinal study
Edwards,
Stephen D.
Abstract: This paper constitutes a
comparative and longitudinal investigation of physical exercise and
psychological wellness in a sample of health club members in Zululand, South
Africa. The research was contextualized within a public health and community
psychological model of mental health promotion. Physical exercise was
categorized as regular or irregular, depending upon whether it met the
criterion of exercising for an average of thirty minutes a day at least three
times per week or not. A Wellness Profile was constructed from various
questionnaires chosen on the basis of their relationship with the general
construct of psychological wellness and administered to samples of health club
members and university students. In the comparative investigation, health club
members were more psychologically well than university students. Whether they
were members of a health club or not, participants who were regular exercisers
were found to be more psychologically well than irregular exercisers. In the
longitudinal investigation, health club members who exercised regularly over a
period of two or more months increased significantly in psychological wellness.
The significance of the findings in themselves and for the promotion of public
and mental health is discussed.
Assessment of leisure and recreation research in Africa
Goslin, Anneliese
Abstract: Leisure and recreation are now
accepted as identifiable research areas. Retrospective and prospective
assessments of research in the field are therefore not only desirable but also
necessary to consolidate what has been learned, clarify concepts and theories
and provide a focus for future research. No such assessments have appeared over
the last two decades in Africa. This might be a reason why leisure and
recreation research here have not yet achieved the same scholarly level and
diversity as in North America. The research assessment framework of Goodale and
Witt has been applied to retrospectively assess the published scholarly work in
the fields of leisure and recreation for the period 1980-2002 and to
prospectively ascertain the opinions of 86 active scholars and practitioners in
the relevant fields on future research directions in 10 African countries. The
overall assessment suggests a moderate growth in quantity, weaknesses in
conceptualisation and theory development and an ad hoc and eclectic approach
with no real principal issues for future research. Recorded research has a short-term
focus and is mostly of the fact-finding type and results are not disseminated
adequately. The disciplinary roots of the research lie in the social sciences.
The main barrier to the development of research seems to be the uninformed or
partially informed attitude of members of the public and decision makers
regarding the role and value of recreation in society.
Fisieke aktiwiteit, lewenstyl en gesondheidstatus by swart
manlike middelvlakbestuurders
Laubscher,
Rines; Strydom, Gert L.; Dreyer, Lukas I.
Abstract: Optimal health could be
significantly influenced by parameters such as physical activity and a healthy
lifestyle. The objective of this study was to determine whether a relationship
exists between leisure-time physical activity, lifestyle and health status of
black male midlevel managers. Two hundred and twenty one (221) participants
were selected from black midlevel management in a company in the public sector
of the North West Province. The type, intensity, frequency and duration of
participation in leisure time physical activity were determined by the physical
activity index (PAI) as suggested by Sharkey. The lifestyle habits and health
status were determined by using the Belloc and Breslow index (BB) and the
illness rating scale (IRS) of Wyler et al. respectively. Analyses of data
indicated significant differences between physical activity and lifestyle as
well as between lifestyle and health status. No significant differences between
physical activity and health status were present. A multiple regression
analyses indicated a relationship between sleep patterns and health. The health
status of the employees could be improved by the implementation of physical
intervention programmes, which could be beneficial for the company on the
long-term.
Elite coaches' perceptions of the characteristics of
decision-making that discriminate between expert and novice basketball players
Lyoka,
Philemon A.; Bressan, Elizabeth S.
Abstract: This study was aimed at discovering
what elite coaches perceive to be the critical characteristics of
decision-making that distinguish expert players from novices in basketball. A
qualitative method of inquiry (the long interview) was followed. The data were
gathered during interviews with five elite coaches. A framework to define
decision-making was created through a systematic analysis of the data by two
investigators with substantial background in top-level basketball. The key
discriminating variables as defined by the elite coaches were: Anticipation
(experts know where to look and have the ability to read the game better than
novices); cognitive knowledge (experts have a more comprehensive knowledge of
the rules and of tactics), self-knowledge (experts have more accurate sense of
their own abilities) and the quality of memory processes (experts make
decisions faster than novices and show more adaptability in their
decision-making). The results of this research confirm expert-novice
differences in anticipation and quality of memory processes found in other
studies of decision-making in sport. The results also underscore the importance
of knowledge structures - declarative, procedural and personal - in the
development of expertise in sport performance.
The contribution of self-efficacy and outcome expectations
in the prediction of exercise adherence
Malherbe,
Dawid G.; Steel, Henry R.; Theron, Wilhelmina H.
Abstract: The positive contribution of
physical activity and exercise to physical and mental health is widely
acknowledged. However, participation in sport and exercise is not as high as
would be expected. In addition to this, people who start exercising often do
not adhere to their exercise programme. This study examined the effectiveness
of Bandura's self-efficacy theory to predict exercise adherence. A sample of
new members at a gymnasium was assessed on a Physical Self-Efficacy Scale, an
Adherence Efficacy Scale and an Outcome Expectancy Scale. The dependent
variable, exercise adherence, was assessed by monitoring the intended and
actual frequency of visits to the gymnasium. Multiple regression analysis was
conducted to test the hypotheses. Results indicated that physical self-efficacy
was a significant predictor of exercise adherence for the total group as well
as for the females seperately. For the males adherence efficacy was a
significant predictor. The results partly confirm the self-efficacy theory of
Bandura and underline the importance of assessing different dimensions of
self-efficacy in adherence research.
An analysis of skills required for selected sectors of the tourism industry
Saayman, Melville; Geldenhuys, Susan
Abstract: Tourism is a relative newcomer to
the academic repertoire and literature on the subject revealed a plethora of
issues which need to be addressed when offering training programmes in tourism
and hospitality studies. One of the most significant problems is the fact that
tourism educators, guided by their individual biases, design tourism curricula
with little or no input from the industry. The aim of the research is to
determine what skills are required by industry for travel agents, tour
operators and tourist guides. A two-pronged approach was followed: A literature
study as well as a survey. For the survey a questionnaire, covering a wide
range of variables divided into eight categories, was used to obtain the
opinions of travel agents, tour operators and tourist guides. The surveys were
conducted as structured telephonic interviews with representatives of cities
and towns in Gauteng Province, Republic of South Africa. The results indicate
which aspects are rated as important by the industry that should be included in
tourism curricula. The results were divided into three categories namely
tourism specific, general and business knowledge.
Thought sampling of cricketers during batting
Slogrove,
Lynn; Potgieter, Justus R.; Foxcroft, Cheryl D.
Abstract: Researchers and practitioners have
expressed the need for the use of qualitative methodological techniques in
sports psychology research. In response to this challenge, the authors applied
a multiple-case study research strategy and in-depth interviews to identify the
experiences of three potentially elite, top-order cricket batsmen during
batting. The content analysis of the thought-sampling data obtained from nine
interviews (i.e., a baseline interview followed by interviews subsequent to one
good and one poor batting innings for each participant) revealed three major
dimensions, namely, cognitions, affect and related behaviours. Within the
cognitive dimension, four categories were identified, namely, task-focused
thoughts, where strategy thoughts were predominant, positive / motivational
thoughts such as self-praise, negative / inappropriate thoughts such as
premeditation of shots and worries and doubts, and lastly, assorted thoughts.
The affect dimension comprised categories of positive / normal affective states
and negative affective states. The categories of related behaviours were
batting strategy, behavioural routines, inter-personal issues, observation,
physical practice, reaction to unfavourable situations, visual focus and
warm-up. Based on the findings of the study, implications for practice are
outlined.
Die meting van assertiwiteit by netbalspelers
Venter,
Ranel E.; Potgieter, Justus R.
Abstract: The purpose of this study was to develop
a questionnaire that measures the assertiveness of netball players. The
identification of typical characteristics and assessment by experts regarding
the correctness and technical presentation of the items resulted in a
preliminary questionnaire. The item analysis for the reduction of items took
place by applying the homogeneity approach and the correlation of the score of
each item with the total score. Ninety-two senior netball players participated
in the major phase of this study. The players completed the preliminary
questionnaire on assertiveness as well as the South African Personality
Questionnaire that served as criterion measure for establishing the validity of
the final form of 22-items. Internal consistency reliability was determined by
means of the split-half-method. Both the reliability (r = 0.834) and validity
(r = 0.297; p < 0.01) of the instrument proved to be satisfactory. It was
concluded that this questionnaire is suitable for use in a netball setting.
