The purpose was to compare the physical fitness level of male fire fighters to the average Canadian population of similar age and sex. Subjects were 1303 fire fighters between the ages of 19 and 58 years, categorized into the following four age groups: 19-29 years (n = 351), 30-39 years (n = 408), 40-49 years (n = 408) and 50-59 years (n = 136). Subjects participated in the Canadian Standardized Test of Fitness including (1) pre-test screening; (2) anthropometric; (3) cardiovascular; (4) flexibility and; (5) muscular endurance measurements. It was hypothesized that there would be no significant differences between the body composition, flexibility, cardiovascular fitness and muscular endurance levels of fire fighters compared to the average Canadian of similar age. Fire fighters had significantly lower VO$ sb2$max values and significantly greater scores for sit-ups, push-ups and flexibility for all age categories, compared to their counterparts. The fire fighters' lower aerobic capacity was attributed to elevated body mass and possible long-term effects of exposure to carbon monoxide and vapours from combustible chemicals.

The present study profiled the fitness characteristics of elite South African surfers. Sixty-one surfers volunteered to participate in the study. Each subject underwent a maximal tests in order to measure peak maximum oxygen uptake, anthropometery, co-ordination, agility, balance, Wingate test, and isokinetic strength assessments of the knee and shoulder in extension and flexion, including shoulder internal and external rotation. Lung function measurements were also measured to assess the lung capacity of the subjects. The cardiovascular demands of surfing was high showing a peak VO2 of 54.9 (+SD=9.73) ml.kg-1.min-t, and a peak VE of 98.3 (+SD=17.8) l.min-1. Actual lung function results obtained by the subjects were greater than predicted scores for age and weight. Anaerobic scores were excellent for surfers as compared to other sportpersons. Balance and agility scores were excellent. Good strength ratios and values were obtained through isokinetic testing, both for the shoulders and the knees. The subjects showed an above level of fitness in all the measurements as compared to other water-based athletes. As a result the research showed that surfing can be best enhanced through the principle of specificity, and that the subjects engaged in this sport can be regarded as elite athletes. / Thesis (M.Sport Sc.)-University of Durban-Westville, 2000.

The main aim of this study was to compare fitness levels of Indian high school boys in two cohorts: 1977 and 1997. A secondary aim was to identify if the same problem areas or strengths still exist in 1997 as in 1977 or if the levels of fitness have further deteriorated or improved, as well as the establishment of norms for boys 14 - 18 years. Ten different Secondary schools from the Durban Metropolitan area participated in this study. The test battery included eight tests measuring four components of motor fitness based on the Fleishman study. The tests that were used consisted of fifty metre shuttle run, fifty metre dash, sit-ups, pull-ups, medicine ball put, shot-put, 250m shuttle run and 12 minute run/walk test. Data from 500 hundred boys were included in the research analysis and these were categorized into 5 different age groups, 13,6 - 14,6 years; 14,7 - 15,6 years; 15,7 - 16,6 years; 16,7 - 17,6 years and 17,7 - 18,6 years. Basic statistical procedures were used to determine the normality of the samples for height and weight in each age group. Standard score tables were drawn for each age group. A paired t-test was used to determine if a significant difference between the means existed. The level of significance was set at 0,05. The means of both studies were compared to ascertain the difference in fitness levels in the two cohorts. The analysis of the data revealed that the fitness status of adolescent boys have deteriorated over two decades. / Thesis (M.A.)-University of Durban-Westville, 2000.

The effect of the perception of fitness on the acquisition of several basic interviewing skills was explored. Furthermore, the relationship between perceived and actual fitness was investigated, as well as the relationship between actual fitness and basic interviewing skills. The interviewing skills were eye contact, talk time, verbal following (topic change) and focus of subject verbalization. / The study consists of two parts. The first part explored the viability of altering an individual's perception of personal physical fitness. Fifty-four subjects were randomly assigned to either the experimental or control condition. Experimental subjects received positive feedback related to their physical fitness during a bicycle ergometer test of actual fitness. Control subjects received only neutral feedback. Results indicated that positive feedback worked to successfully alter perception of fitness among experimental subjects. / The second part of the study explored the effect of fitness perception on interviewing skill acquisition. Results indicated that increasing an individual's perception of personal fitness did not enhance skill acquisition. There was also no significant difference in skill acquisition among subjects with higher and lower levels of perceived fitness. It was further determined that no significant relationship existed between actual fitness and the acquisition of basic interviewing skills used in the study. Additionally, it was determined that although a significant relationship between perceived and actual fitness was evident for female subjects in the study, this relationship did not hold true for male subjects.

The purpose of this study was to better understand how an individual's quality of life and person-environment fit effect participation in health/wellness programs. A previous study (Nicholas, 1990) on person-environment fit provided a data pool to assess quality life. Faculty, professional personnel, staff personnel, and service personnel at Ball State University completed 230 Work Environment Scale (WES) Real and Ideal Forms and 158 quality of life questionnaires and personal profile forms. One hundred fifty-eight sets of data were used in this study. Chi-square analysis of demographic variables found significant differences between age groups and occupational categories in their tendency to participate. Multivariate analysis of variance of quality of life and person-environment fit score means found that neither could predict participation as Pillais F value was not significant. Pearson r correlation coefficients found significance between quality of life and person-environment fit scores. Stepwise multiple regression of quality of life concern measures found only the concern related to personal health as a predictor of participation. The results of this study do not conclusively support a relationship between either quality of life or person-environment fit and participation. Further study is recommended. / Institute for Wellness

Exercising at an appropriate training intensity for individuals is important for improvement of cardiorespiratory fitness. The American College of Sports Medicine (ACSM) has recommended that healthy adults exercise at an intensity of 60-80% maximal heart rate reserve (MHRR). The ventilatory threshold (VT) has also been recommended for use to determine intensity for exercise prescription. The purpose of this study was to compare the heart rate at the VT (VTHR) and at 60-80% MHRR. A secondary purpose was to determine the relationship, if any, between age, gender, height, weight, body mass index, percent body fat, resting heart rate, physical activity status (PAS), smoking history, and rating of perceived exertion (RPE) at 60 and 80% Hrmax and the difference between the VTHR and 60% MHRR. Subjects were 373 apparently healthy or high risk (as defined by ACSM, 2) individuals (209 men, 164 women), ages 19-77 (46.1+12.8 yr.), from the Ball State University Adult Physical Fitness Program who performed a maximal treadmill test between 1992-1994. VT was selected using a computerized V-slope method by the SensorMedics 2900TI Metabolic Measurement Cart. The VTHR (125.2+16.9) was significantly lower than the 60-80% MHRR (133.1+10.8 to 154.5+12.7) (p<0.05). Two hundred and sixty two subjects (70.1%) were below 60% MHRR and 3 subjects (0.8%) were above 80% MHRR at the VTHR. Multiple regression analysis explained 11.2% of the variance in the difference between the VTHR and 60% MHRR using RPE at 60% HR,,,, PAS, and smoking history. For the majority (70.2%) of the adults in this study, the VTHR falls below the traditional THR of 60-80% MHRR. The 60-80% MHRR would appear to be an appropriate exercise training intensity for cardiorespiratory benefit and therefore the %MHRR range alone would seem to be an adequate training intensity. Further study related to the VTHR is warranted to determine its application, if any, to exercise prescription intensity. / School of Physical Education
