Abstract Fishbein's Behavioral Intention Model was examined in a study of the beliefs, attitudes, and behavioral intentions of women and men toward regular jogging. Data were collected from 296 female and male joggers and nonexercisers who were 30 years of age and older using a mail questionnaire which was constructed according to Fishbein's specifications. Significant and meaningful differences were found between joggers' and nonexercisers' beliefs. Nonexercisers thought jogging would require too much discipline, take too much time, and make them too tired. Joggers were more likely than nonexercisers to believe that regular jogging would have positive effects, and joggers evaluated being in good physical and mental condition more positively than nonexercisers. Nonexercisers indicated it was unlikely their referents (particularly physicians) thought they should jog regularly. The results supported the theory upon which the model was based: the relationship between the intention to jog and jogging behavior was high (r = .82) and behavioral intention was predicted from an attitudinal and a normative component alone (R = .742). The results of the study suggest that educators can develop behavior change strategies by focusing on change of beliefs and attitudes identifiable through the model. 相似文献

Purpose The aim of this study was to test the hypothesized structural paths in Bandura's social-cognitive theory (SCT) model on adolescent girls' physical activity following a 12-month physical activity and dietary intervention to prevent obesity. Method We conducted a 12-month follow-up study of 235 adolescent girls (M age = 13.2 years, SD = 0.4) from 12 secondary schools located in low-income communities. At baseline, participants completed SCT scales related to physical activity (i.e., self-efficacy, intention, parental support, and outcome expectations). At baseline and 12-month follow-up (postintervention), participants wore accelerometers for 7 days. Structural equation modeling was used to determine if Time 1 measures predicted physical activity at 12-month follow-up after adjusting for baseline activity. Results The model explained 28% and 34% of the variance in physical activity and intention, respectively. Model fit indexes indicated the data were a good fit to the model; however, only self-efficacy was associated with physical activity at 12 months. There was no support for intention or outcome expectations as proximal determinants of behavior. Self-efficacy was associated with outcome expectations and parental support; however, only outcome expectations predicted intention. Conclusions Current findings indicate a large proportion of the variance for physical activity and intention remains unexplained and that the proposed pathways in the SCT model were not fully supported. Future model testing may need to consider augmentation or integration of theoretical models, which may include ecological components if we are to advance our understanding of physical activity behavior in this subgroup of the adolescent population. 相似文献

This study described the activity patterns of students in a high school fitness class and explored the structural relationships between particular student characteristics and their systematically coded exercise behavior. Although percent of time spent jogging was low (18%), with no gains made in cardiovascular fitness, the amount of time spent jogging, the distance covered, and fitness level were all significantly correlated. A LISREL VI computer program was used to test a structural equation model representing the Fishbein Behavioral-Intention Model. In support of the model, results showed the prediction of exercise behavior by attitude and subjective norm was significantly mediated by intention. Although not significant, it is worth noting that subjective norm was found to be the stronger predictor of intention over attitude. Background variables were found to indirectly influence intention through their significant influence on attitude and subjective norm. For this sample of 9th and 10th graders, significant others, particularly their peers and teachers, had a stronger impact on behavior than personal attitudes about activity. 相似文献

Purpose: This study tested two hypotheses relating young athletes’ sports motivations to parental behaviors and cognitive appraisal: (1) young athletes’ motivation in sports is related to their parents’ behavior; and (2) this relationship is mediated by cognitive appraisal, even after controlling for competitive level and sports records. Method: This cross-sectional study included 673 young athletes and it measured the athletes’ perceptions of parental behaviors, cognitive appraisal, and sports motivation. Results: Structural equation modeling confirmed Hypothesis 1–the mother’s behaviors accounted for 15 to 16% of the variance in sports motivation, and the father’s behaviors accounted for 12 to 21% of the variance. The correlation patterns differed according to whether the athletes were evaluating the mother’s or father’s behaviors. Hypothesis 2 also was confirmed, for cognitive appraisal partially mediated the relationship between the perception of parental behaviors and sports motivation (34% of the variance was accounted for by the perception of the mother’s behavior; 30% by the father’s). The mediating model did not vary with competitive level or sports records. Conclusion: Parental behaviors and cognitive appraisal need to be taken into account to understand young athletes’ sports motivations. 相似文献

BackgroundLittle is known about the association between different types of physical activity (PA) and chronic back conditions (CBCs) at the population level. We investigated the association between levels of total and type-specific PA participation and CBCs.MethodsThe sample comprised 60,134 adults aged ≥16 years who participated in the Health Survey for England and Scottish Health Survey from 1994 to 2008. Multiple logistic regression models, adjusted for potential confounders, were used to examine the association between total and type-specific PA volume (walking, domestic activity, sport/exercise, cycling, football/rugby, running/jogging, manual work, and housework) and the prevalence of CBCs.ResultsWe found an inverse association between total PA volume and prevalence of CBCs. Compared with inactive participants, the fully adjusted odds ratio (OR) for very active participants (≥15 metabolic equivalent h/week) was 0.77 (95% confidence interval (CI): 0.69–0.85). Participants reporting ≥300 min/week of moderate-intensity activity and ≥75 min/week of vigorous-intensity activity had 24% (95%CI: 6%–39%) and 21% (95%CI: 11%–30%) lower odds of CBCs, respectively. Higher odds of CBCs were observed for participation in high-level manual domestic activity (OR = 1.22; 95%CI: 1.00–1.48). Sport/exercise was associated with CBCs in a less consistent manner (e.g., OR = 1.18 (95%CI: 1.06–1.32) for low levels and OR = 0.82 (95%CI: 0.72–0.93) for high levels of sport/exercise).ConclusionPA volume is inversely associated with the prevalence of CBCs. 相似文献

Abstract Twenty-one middle-aged males who participated in a jogging program performed a 6-minute submaximal exercise bout on a bicycle ergometer to determine if any differences existed between the results of heart rate and blood pressure tests taken before and after 10 weeks of training. Heart rates were obtained from electrocardiograph tracings and blood pressures were measured by a manual sphygmomanometer. The t test for differences between the means of related measures of heart rates and blood pressures was used with the .01 level selected for significance. Differences between the means of pre-and post tests of heart rate, under pre-exercise, submaximal exercise, and postexercise conditions, were all statistically significant. The jogging program did not produce any significant change in either systolic or disastolic blood pressure. It was concluded that 10 weeks of participation in a systematic jogging program will produce reductions in heart rates for middle-aged men at rest, during submaximal exercise, and during the recovery period following exercise. 相似文献

BackgroundEmerging epidemiological evidence suggests that compared to engaging in 1 activity mode alone, a combination of moderate-to-vigorous physical activity (MVPA: brisk walking/jogging, cycling) and muscle-strengthening exercise (MSE: push-ups/sit-ups, using weight machines) has more favorable associations with optimal weight status. However, few studies have examined the dose-dependent and joint associations of MVPA and MSE with obesity.MethodsBased on cross-sectional analyses of the European Health Interview Survey Wave 2 (2013–2014), we examined prevalence ratios (PRs) of joint and stratified associations between MVPA (4 categories: (i) 0 min/week, (ii) 1–149 min/week, (iii) 150–299 min/week, and (iv) ≥300 min/week) and MSE (3 categories: (i) 0 day/week, (ii) 1 day/week, and (iii) ≥2 days/week) with body mass index-defined obesity (body mass index of ≥30.0 kg/m2) using Poisson regression with robust error variance. PRs were examined unadjusted and adjusted for sociodemographic and lifestyle characteristics (e.g., sex, age, education, income, and smoking status).ResultsData were available for 280,456 adults (≥18 years), of which 46,166 (15.5%) were obese. The interaction MVPA × MSE guideline adherence was statistically significant for obesity (p ≤ 0.05). The joint MVPA–MSE analysis showed that compared to the reference group (i.e., no MVPA and no MSE), the PRs followed a dose-dependent pattern, with the lowest observed among those reporting ≥150 MVPA min/week and ≥1 MSE days/week (PR: 0.43; 95% confidence interval: 0.41–0.46). When stratified across each MVPA strata, the PRs were mostly lower among those engaging in MSE 1 day/week, as compared to those doing MSE ≥2 days/week.ConclusionThere was evidence for a dose-dependent association between joint MVPA–MSE with a reduced prevalence of obesity. Public health strategies for the prevention and management of obesity should recommend both MVPA and MSE. 相似文献

Abstract Generalizability theory was utilized to investigate the amount of variation associated with various facets in the assessment of skinfolds as suggested by the American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) Health Related Physical Fitness Test. The facets utilized were testers, instruments, and repeated trials. Results indicate that the variation associated with the tester, instrument, and trial facets was small. Components of variance and G coefficients indicate that skinfold measures vary little depending upon the tester, instrument, or trial used. Suggestions are made for accurate assessment of the skinfolds recommended in the AAHPERD Health Related Physical Fitness Test. 相似文献

Abstract The bradycardia effect of a 10-week jogging program was studied in 13 previously sedentary middle-aged subjects (seven women and six men). This response during standardized submaximal treadmill walking and leg cycling was related to changes in cardiac output ([Qdot]), stroke volume (SV), and arteriovenous oxygen differences (a-vO2 diff). Heart rate (HR) response was also studied during load carrying and arm cycling tasks, and a [Vdot]O2 max test was administered. All tests were repeated posttraining. The posttraining increases in [Vdot]O2 max (ml/kg × min-1) were 19.7% and 14.8% for the men and women respectively. Training also produced significant reductions in submaximal HR and Q during treadmill and leg cycling exercise. A-vO2 diff rose, while there were no changes in [Vdot]O2 during the submaximal work tasks, suggesting either altered blood flow or a greater capacity to utilize O2 by the working muscle. Both men and women showed significant reductions in HR during the arm cycling and load carrying as well. These data suggest that a jogging program can alter cardiovascular function in tasks other than running. The magnitude and direction of change showed no sex differences; therefore, it was also concluded that there are no differences in the trainability of previously sedentary middle-aged men and women. 相似文献

AbstractThe purpose of this study was to validate peak acceleration data from an accelerometer contained within a wearable tracking device while walking, jogging and running. Thirty-nine participants walked, jogged and ran on a treadmill while 10 peak accelerations per movement were obtained (n = 390). A single triaxial accelerometer measured resultant acceleration during all movements. To provide a criterion measure of acceleration, a 12-camera motion analysis (MA) system tracked the position of a retro-reflective marker affixed to the wearable tracking device. Peak raw acceleration recorded by the accelerometer significantly overestimated peak MA acceleration (P < 0.01). Filtering accelerometer data improved the relationship with the MA system (P < 0.01). However, only the 10 Hz and 8 Hz cut-off frequencies significantly reduced the errors found. The walk movement demonstrated the highest accuracy, agreement and precision and the lowest relative errors. Linear increases in error were observed for jog compared with walk and for run compared to both other movements. As the magnitude of acceleration increased, the strength of the relationship between the accelerometer and the criterion measure decreased. These results indicate that filtered accelerometer data provide an acceptable means of assessing peak accelerations, in particular for walking and jogging. 相似文献

This study investigated the effects of successive matches on match-running in elite under-23 soccer players during an international tournament. Match-running data was collected using a semi-automated multi-camera tracking system during an international under-23 tournament from all participating outfield players. Players who played 100% of all group stage matches were included (3 matches separated by 72 h, n = 44). Differences in match-running performance between matches were identified using a generalised linear mixed model. There were no clear effects for total, walking, jogging, running, high-speed running and sprinting distance between matches 1 and 3 (effect size (ES); ?0.32 to 0.05). Positional analysis found that sprint distance was largely maintained from matches 1 to 3 across all positions. Attackers had a moderate decrease in total, jogging and running distance between matches 1 and 3 (ES; ?0.72 to ?0.66). Classifying players as increasers or decreasers in match-running revealed that match-running changes are susceptible to individual differences. Sprint performance appears to be maintained over successive matches regardless of playing position. However, reductions in other match-running categories vary between positions. Changes in match-running over successive matches affect individuals differently; thus, players should be monitored on an individual basis. 相似文献

Abstract The aim of the study was to examine the relationships between physical activity and several health parameters in German adolescents. We predicted that the association between physical activity and physical and psychosocial health resources (physical and psychosocial characteristics that tend to enhance coping and well-being) would be stronger than the association between physical activity and health deficits. This research is based on a large representative, cross-sectional study (the German Health Interview and Examination Survey [KiGGS] and the Motoric-Module [MoMo]). Health was assessed using medical parameters, motor fitness data, and questionnaire data for various health-related parameters. To assess physical activity, the participants answered questions regarding the duration and intensity of weekly physical activity in leisure and organized sports. We tested our assumptions using a representative sample (N=2291; 50.5% boys) of German adolescents aged 11–17 years. Participants were classified as physically inactive (16.7%), somewhat active (24.7%), medium active (19.8%), active (14.4%) or highly active (24.4%), based on the duration and intensity of their weekly physical activity. In support of our hypothesis, the data revealed that the amount of physical activity explains up to 12.6% in the variance of physical and psychosocial health resources, but only 2.5% of the variance in physical and psychosocial health deficits. We conclude that the relationship between physical activity and health among adolescents should not only be viewed as a way of reducing health deficits, but should also focus on the enhancement of physical and psychosocial resources. 相似文献

ABSTRACTPurpose: The purpose of this study was to examine the predictive relationship among physical activity, health-related fitness, and on-task classroom behavior in children using a discriminant function analysis. Method: Participants were a convenience sample of children (N = 533; Mage = 8.8 ± 1.9 years) recruited from 77 1st- through 5th-grade classrooms at 3 low-income schools in a capital city in the Southwest United States. Percent of the school day spent in sedentary behavior (%SED), moderate-to-vigorous physical activity (%MVPA), and health-related fitness scores (body mass index [BMI] and Progressive Aerobic Cardiovascular Endurance Run [PACER] laps) were assessed during school hours. Classrooms were observed for on-task behavior during the academic year with the use of 5-s momentary time sampling methodology. A discriminant function analysis was performed using a binary on-task behavior outcome, stratified by an 80% on-task behavior cut point. Results: The results yielded 1 function (r2 = .26, F = 13.1) explaining approximately one quarter of the total variance. The standardized function coefficients were ?.29, .29, ?.48, and .48 for %SED, %MVPA, BMI, and PACER laps, respectively. The sensitivity and specificity of the derived function for classifying a child into an on-task or off-task classroom were .79 and .73, respectively. Children who belonged to classrooms that achieved 80% on-task behavior displayed shorter times in sedentary behaviors (d = 1.01), lower BMI (d = 0.13), and higher PACER scores (d = 0.22) compared with children who belonged to off-task classrooms. Conclusion: School-day physical activity behaviors and health-related fitness scores can moderately discriminate children who belong to classrooms from low-income schools that are categorized as being sufficiently on task. 相似文献

BackgroundThe social environment might play an important role in explaining people's physical activity (PA) behavior. However, little is known regarding whether personal networks differ between physically active and physically inactive people. This study aimed to examine the relationship between personal network characteristics and adults' physical (in)activity.MethodsAn egocentric social network study was conducted in a random sample in Switzerland (n = 529, mean age of 53 years, 54% females). Individual and personal network measures were compared between regular exercisers and non-exercisers. The extent of these factors' association with PA levels was also examined.ResultsNon-exercisers (n = 183) had 70% non-exercising individuals in their personal networks, indicating homogeneity, whereas regular exercisers (n = 346) had 57% regularly exercising individuals in their networks, meaning more heterogeneous personal networks. Additionally, having more regular exercisers in personal networks was associated with higher PA levels, over and above individual factors. Respondents with an entirely active personal network reported, on average, 1 day of PA more per week than respondents who had a completely inactive personal network. Other personal network characteristics, such as network size or gender composition, were not associated with PA.ConclusionNon-exercisers seem to be clustered in inactive networks that provide fewer opportunities and resources, as well as less social support, for PA. To effectively promote PA, both individuals and personal networks need to be addressed, particularly the networks of inactive people (e.g., by promoting group activities). 相似文献

Abstract The effect of attentional focus on the perception of physical work was examined by using a work reproduction design. Subjects performed a fixed interval of work at either 50 or 75% of their predicted VO2 max, during which they were required either to solve a continuous flow of arithmetic problems or to perform in an unfilled control condition. On a subsequent trial, without a concomitant attention-demanding task, subjects were asked to reproduce the amount of work that they had previously performed. It was found that individuals in the control condition produced a significantly greater amount of work on the reproduction trial, while those in the attentional focus condition performed about the same amount as on the previous trial. No interaction was found between attentional focus and work load. 相似文献

ABSTRACTThis study modelled children’s gross motor coordination, investigated sex-differences and identified the effects of fixed and dynamic correlates on motor coordination development. A total of 344 Portuguese children (170 girls), from 6 age cohorts (5 to 9 years of age), were followed consecutively for three years (age range 5 to 11 years) using a mixed-longitudinal cohort design. Birth weight, hand dominance and socioeconomic status (SES) were identified. Gross motor coordination, body mass index, physical fitness (PF) and physical activity (PA) were assessed annually. A sequence of multilevel hierarchical linear models were developed. Model 1 found that age, age2, sex, sex-by-age and sex-by-age2 were significant predictors (p < 0.05) of gross motor coordination. Boys outperformed girls from 6 years of age onwards. Model 2 found a cohort effect (p < 0.05). Model 3 found that right handers were more coordinated (p < 0.05). When the confounders of body mass index, PF and PA were added to the model (Model 4) it was found that boys and girls had parallel trajectories in their gross motor coordination development. In conclusion children with increasing body mass index were less coordinated, while those who were stronger and more agile had steeper trajectories of gross motor coordination with age. 相似文献

BackgroundSince the shutdowns associated with the coronavirus disease 2019 pandemic, there has been limited discourse on physical activity (PA) recovery (i.e., the ability of individuals to resume PA at pre-pandemic levels), including recovery rate, speed of recovery, which individuals are able to return quickly, who is left behind, and what are the causes of those differences. This study aimed to estimate the level and shape of PA recovery rate in Thailand.MethodsThis study employed 2 rounds (2020 and 2021) of Thailand's Surveillance on Physical Activity dataset for the analysis. Each round included over 6600 samples from individuals aged 18 years or older. PA was assessed subjectively. Recovery rate was calculated from the relative difference in the cumulative minutes of moderate-to-vigorous PA (MVPA) from 2 different periods.ResultsThe Thai population experienced a medium level of recession of PA (−26.1%) and a moderate level of recovery of PA (37.44%). PA recovery in the Thai population resembled an imperfect V shape, reflecting a sharp decline followed by an immediate upturn; still, recovered PA remained lower than pre-pandemic levels. The quickest recovery was found among older adults, whereas students, young adults, residents of Bangkok, the unemployed, and those who had a negative attitude toward PA experienced the highest recession of PA and were among the slowest to recover.ConclusionThe level of recovery of PA among Thai adults is largely determined by the preventive behaviors demonstrated by groups within the population who have a higher awareness of their health. The effect of the mandatory coronavirus disease 2019 containment measures on PA was temporary. However, the slower recovery rate of PA among some individuals was caused by a combination of restrictive measures and socioeconomic inequality, which required more time and effort to overcome. 相似文献
