促进身体锻炼行为的阶段性改变理论研究述评

身体锻炼行为转变的研究源自促进个体健康的研究,身体锻炼行为研究是健康促进研究的一个重要领域。促进身体锻炼行为的研究是这一领域的重要内容。为了解释身体活动行为或者为了说明身体锻炼行为受哪些因素影响,研究人员提出了一些身体锻炼行为的理论模型,行为的阶段性改变理论是其中重要的理论之一。行为的阶段性改变模式把行为阶段和过程的概念应用到为了行为的改变而设计的可变程序活动中。这些阶段通过一系列修正行为的活动与行为改变联系在一起,认为修正行为的活动过程就是行为改变的过程。     

Changing the environment to promote health-enhancing physical activity

Supportive environments have been used to change and influence health behaviours like smoking. While psychological and ecological theories and models demonstrate the possible influences of the environment on health-enhancing physical activity (HEPA), little is known about the effectiveness of the environmental interventions. This paper presents the results of a systematic review of studies that used environmental interventions to increase health-enhancing physical activity. Two groups of studies were found, studies that changed the physical environment by creating new HEPA facilities, policies and supporting mechanisms, and studies that used the elements of the environment as an active or sedentary ‘point of choice’, via educational materials to promote stair use. Environmental change studies showed a small increase on HEPA behaviour, but the relative impact of environment changes was not evaluated. A number of before and after studies have observed a weak effect of a simple environmental change to stimulate stair climbing while travelling or shopping. Current national policy has embraced the environment as an option for promoting health-enhancing physical activity, especially active travel, in spite of the lack of effectiveness data. It is recommended that existing or planned public health environment and HEPA initiatives should use appropriate evaluation methods to assess their efficacy and effectiveness. Further developmental research into the nature of the relationship of the environment to particular HEPA behaviours is strongly recommended before developing new environmental interventions.

Association between physical activity and health in German adolescents

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.     

Validation of a short physical activity recall questionnaire completed by Spanish adolescents

Abstract

Self-report recall questionnaires are commonly used to measure physical activity in children and adolescents. However, they have been shown to have low to moderate validity, mainly due to inaccuracies in recall activity. The purpose of the present study was to determine the reliability and validity of an adapted version of the Assessment of Physical Activity Levels Questionnaire (APALQ) among a sample of Spanish adolescents. Test–retest reliability of the APALQ was assessed using a sample of 150 adolescents (72 males, 78 females), aged 13.6±1.1 years, who answered the APALQ twice within 7 days. Criterion validity was assessed using a sample of 77 adolescents (50 males, 27 females), aged 13.6±1.1 years, by comparing the APALQ against the Computer Science and Application (CSA) monitor. All participants were volunteers recruited from local schools in the Aragon region of Spain. Test–retest reliability for all items was high with intra-class coefficients of 0.77 for boys and 0.74 for girls. The APALQ demonstrated modest criterion validity with Pearson correlation coefficients (r) ranging from 0.53 between Physical Activity Index (PAI) and CSA minutes of moderate and vigorous physical activity, and 0.47 between PAI and CSA steps per day. When the data were analysed by gender, girls had higher correlations than boys (P < 0.01). The Spanish APALQ seems to be a valid and reliable short self-report physical activity questionnaire.     

大学生身体活动阶段变化与健康状况关系的研究

基于锻炼心理学领域中的"从无活动到保持活动的4步骤模型"(Four Steps from In-activity to Activity;FIT模型),以3 807名大学生为研究对象,探讨了大学生身体活动阶段变化与健康状况变量(身体体质、主观良好感、健康满意度和不适感)之间的关系。研究结果表明,处于活动阶段的个体,其健康状况水平均好于处于不活动阶段的个体;在3个活动阶段上,处于保持期(即长期保持规律性身体活动)的个体,其健康状况水平均好于处于探索期和波动期的个体;人口统计学变量和健康状况变量共同解释了17.6%的阶段方差变异(F=108.48,P<0.05)。验证了FIT模型中大学生身体活动阶段变化与健康状况之间的相关关系,为今后运用FIT模型诊断大学生身体活动变化阶段及其相应健康状况提供了实证依据。     

Population physical activity behaviour change: A review for the European College of Sport Science

Abstract

The academic study of sport and exercise science has expanded greatly into the arena of public health over the past 20 years or more and Europe has played a significant role in this. It is opportune to review evidence concerning ways to change population levels of physical activity for health. This paper summarises such evidence by using a lifespan approach with physical activity behaviour change for children and adolescents, adults and older adults. Correlates of physical activity are identified and the outcome of interventions is discussed. Intervention success has been variable often due to weak fidelity and short-term implementation, and process evaluation is missing from many such studies. Nevertheless, evidence points to possible behaviour change across all age groups and through multiple settings, including schools, worksites and the community.     

Social influence in relation to current and intended physical activity among adolescents

Abstract

The aim of the present study was to examine the impact of social support and negative social influence from various contexts on adolescents’ current and intended physical activity. Questionnaire data were obtained from 1156 students aged 16–17 years. Relationships among variables were examined with principal component analysis and structural equation modelling. Social influence from several contexts was strongly related to current and intended physical activity, particularly among students in work preparing school programmes. Social support in a sport club context provided the strongest unique contribution to the relationship with physical activity, and social support from an outside perspective (e.g. suggestions, help to plan, and positive talk about physical activity), from the contexts school and leisure, had multidimensional effects. Social support could exist in tandem with experiences of negative social influences (e.g. complaints, critique, teasing). In conclusion, it is necessary to expand our understanding of processes that surround supportive as well as negative social influences on adolescents’ level of physical activity and distinguish between main, buffering, and intervening effects of social support.

Health-enhancing physical activity and sedentary behaviour in children and adolescents

We provide a wide-ranging review of health-related physical activity in children and adolescents using a behavioural epidemiology framework. In contrast to many other reviews, we highlight issues associated with true sedentary behaviours alongside physically active behaviours. Specifically, we review the evidence concerning the links between physical activity and cardiovascular disease, overweight and obesity, psychosocial measures, type II diabetes, and skeletal health. Although the evidence is unconvincing at times, several factors lead to the conclusion that promoting physical activity in youth is desirable. A review of the prevalence of physical activity and sedentary behaviours shows that many young people are active, but this declines with age. A substantial number are not adequately active for health benefits and current trends in juvenile obesity are a cause for concern. Prevalence data on sedentary behaviours are less extensive but suggest that total media use by young people has not changed greatly in recent years. Most children and adolescents do not exceed recommended daily hours of TV viewing. Physical activity is unrelated to TV viewing. We also identified the key determinants of physical activity in this age group, highlighting demographic, biological, psychological, behavioural, social and environmental determinants. Interventions were considered for school, family and community environments. Finally, policy recommendations are offered for the education, governmental, sport and recreation, health, and mass media sectors.     

A longitudinal assessment of the links between physical activity and physical self-worth in adolescent females

Abstract

A longitudinal framework was used to examine the hypotheses of (1) whether physical activity predicts changes in physical self-worth or (2) whether physical self-worth predicts changes in physical activity in adolescent girls. Participants (n=272) completed measures of physical self-worth and participation in physical activities at three different points spanning a two-year interval. A cross-lagged panel model using structural equation modelling analyses indicated that physical self-worth predicted subsequent physical activity and physical activity in turn predicted subsequent physical self-worth across time. Findings demonstrated a reciprocal relationship between physical self-worth and physical activity during early adolescence. This study supports the use of the reciprocal effects model (REM) in gaining an understanding of the cross-lagged relationships between physical self-worth and participation in physical activities amongst adolescent girls.

Accelerometry to measure physical activity in toddlers: Determination of wear time requirements for a reliable estimate of physical activity

Accelerometry is widely used to evaluate physical activity in toddlers however recommendations regarding wear time are needed to understand physical activity behaviours in this age group. This study aimed to determine the minimum wear time to reliably evaluate physical activity in toddlers. Children from the 3D Birth Cohort (n = 255, 49.8% boys, 2.1 ± 0.2 years) were asked to wear an accelerometer (GT3X+, ActiGraph) for 7 days. Physical activity was expressed in active time (min/day) and counts per minute (CPM). Single day intraclass correlation coefficients (ICCs) were calculated to assess the effect of varying minimal wear time on reliability estimates. The Spearman-Brown formula was used to determine wear time required to achieve reliability levels of 70%, 80% and 90%. For active time, a reliability of 72.1% was achieved with wearing the accelerometer for ≥ 4 days of ≥ 6 h, which comprised 85.9% of the sample. For CPM, ≥ 4 days of ≥ 6 h provided a reliability of 74.7% and comprised 85.9% of the children. Results differed slightly when girls and boys were analysed separately, but restricting analyses to children with a weekend day did not. In summary, a minimum of 4 days with ≥ 6 h of accelerometry data provides a reliable estimate of physical activity in 2-year toddlers.

A cross-cultural study of adolescents' physical activity levels in France and Spain

Abstract

The goals of this study were (1) to describe and compare levels of physical activity (PA), assessed by accelerometry, of adolescents in two close Spanish and French cities according to gender and period of the week and (2) to assess, with reference to country and gender, the extent to which international PA guidelines were fulfilled. The PA of 401 adolescents (53.37% females) from France and Spain (55.72% French) aged 14.45±0.67 years was assessed with GT3X accelerometers for seven consecutive days to evaluate their habitual levels of moderate to vigorous physical activity (MVPA). Data collection took place from September to December 2010 in six public and state schools in France and Spain. There were significant differences in MVPA in terms of country, gender and period of the week. Spanish adolescents were more active than French adolescents, boys were more active than girls and MVPA was higher on weekdays than at weekends. French girls showed the lowest level of PA. Only 35.9% of the whole sample met the guidelines for PA in both countries. Governments of relevant countries, especially France, should adopt PA promotion policies targeted at adolescents in order to enhance their compliance with PA guidelines.     

The effects of an enhanced quality Physical Education programme on the physical activity levels of Grade 7 learners in Potchefstroom,South Africa

Background: The absence of Physical Education (PE) from the South African school curriculum before its reintroduction in recent years contributed to health concerns regarding the low physical activity (PA) levels of children and adolescents in South Africa.

Purpose: This study evaluated the effects of a once-a-week enhanced quality PE programme on the PA levels of South African Grade 7 learners.

Methods: Using a pre-test and post-test control-group design, 110 Grade 7 learners aged 12–13 years (experimental school, n?=?40; control schools, n?=?70) from two primary schools in Potchefstroom, South Africa, were studied. They participated in a 12-week PE intervention programme based on the guidelines of the South African Curriculum and Assessment Policy Statement, which allocates one hour per week to PE teaching. The intervention included five quality-enhancing components, namely well-trained teachers, homework activities, a reward system, hand-made apparatus and the monitoring of activity intensity. In the experimental school, 40 learners were randomly assigned from the total Grade 7 class (n?=?124) to the experimental group, while two control groups (n?=?37 and n?=?33) were used, one from the same school as the experimental school and the other from a different school. Additionally, to control for PE teacher interaction effect, the experimental group was divided into 4 experimental sub-groups of 10 learners each, which were taught by 4 different PE teachers, and the pre-test and post-test data of these experimental sub-groups were also analysed. Children's PA levels were measured before and after the intervention using a validated Children's Leisure Activities Study Survey questionnaire. The Kruskal–Wallis and Wilcoxon signed-rank tests were used to evaluate the effects of the intervention programme.

Results: No significant differences were found within the experimental group between the 4 experimental sub-groups and between the 2 control groups at pre- and post-test measurements (p?>?.05). There was a significant effect for the experimental group as a whole, as results of the total experimental group showed statistically significant increases in moderate PA (ES?=?0.47; p?=?.014), vigorous PA (ES?=?0.48; p?=?.012) and total PA (ES?=?0.51; p?=?.008) as well as decreases in sedentary behaviours (ES?=?0.39; p?=?.041) after the 12-week intervention programme, whereas no significant changes were found in the control group. Statistically significant improvements were also found in all 4 experimental sub-groups between pre- and post-tests for the time spent in moderate PA (p?=?.028–.05; ES?=?0.23–0.64), vigorous PA (p?=?.018–.036; ES?=?0.23–0.63), total PA (p?=?.017–.05; ES?=?0.30–0.68) and sedentary time (p?=?.014–.049; ES?=?0.26–0.66), whereas no marked changes were observed among the two control groups, indicating no PE teacher interaction effect on the results.

Conclusions: The enhanced quality PE programme can be used as a valuable framework for PE implementation targeted at promoting learners’ PA levels, even in the presence of restricted time allocation, and limited teaching and learning resources.
