conducted by two sets <strong>of</strong> 10 repetitions (3s for eccentric and concentric actions, 1-s pause) <strong>of</strong> push up, reverse push up, sit up, side arm<br />

back extension, half squat, hip lift. Each training items <strong>of</strong> interval was one minute. It was measured height, weight, body mass index,<br />

body fat, brachial blood pressure, ankle blood pressure, brachial-ankle pulse wave velocity (baPWV), pulse pressure, heart rate by four<br />

times (before training, four weeks, eight weeks, twelve weeks) for twelve weeks. Subjects rested in the supine position for 10 min before<br />

measurements. baPWV was measured using formPWV/ABI (Colin Co., Ltd, Komaki, Japan) and by the oscillometric method. This device<br />

recorded the PWV, blood pressure, an electrocardiogram.<br />

There were no significant differences in the before training baPWV among the four groups. Blood pressure, pulse pressure and heart rate<br />

were unchanged by slow speed resistance training for eight weeks. %HRmax was 47±4.04 during the slow training.<br />

Consequently, it was clarified that arterial stiffness was not changed by slow speed resistance training <strong>of</strong> one’s own weight for eight<br />

weeks.<br />

MEASURING PHYSICAL ACTIVITY IN ACTIVE COMMUTING<br />

SCHANTZ, P., STIGELL, E.<br />

THE RESEARCH UNIT FOR MOVEMENT, HEALTH AND ENVIRONMENT<br />

Purpose<br />

From a public health point <strong>of</strong> view it is <strong>of</strong> interest to position different forms <strong>of</strong> existing physically active behaviours in relation to potential<br />

health outcomes. In order to do so, there is a need to establish the energy turnover per week related to a certain form <strong>of</strong> physical activity.<br />

With a research focus on active commuting, it is possible to combine data on route distance, frequency <strong>of</strong> trips per week and energy<br />

demands per kg body weight and km <strong>of</strong> commuting. For this purpose is has proven to be necessary to develop different methods, and<br />

recently we have established a criterion method for route distance measurements (Schantz & Stigell 2009). For reasons <strong>of</strong> simplicity and<br />

large scale studies, the aim <strong>of</strong> this study is to investigate whether other <strong>of</strong>ten used methods for estimating route distances are valid and<br />

reproducible.<br />

Methods: A total <strong>of</strong> 133 individuals participated in the study after having been recruited while walking or cycling to work in the inner urban<br />

area <strong>of</strong> Stockholm, Sweden. They drew their commuting routes on maps and answered different questions in a questionnaire twice, with<br />

slightly more than two weeks in between. Route distances were determined with the criterion method (Schantz & Stigell 2009) and compared<br />

with distance values obtained by four other methods: self-reported data, straight-line distance, geographic information system<br />

(GIS) modelled shortest routes and global positioning system (GPS).<br />

Results: No order effects were noted for any <strong>of</strong> the methods. All <strong>of</strong> them, with self-reported data being the sole exception, displayed a<br />

very high reproducibility. However, to varying degrees, the methods either under- or overestimated the route distances (range: -21 to<br />

+27%).<br />

Conclusion: The study reveals that a number <strong>of</strong> methods commonly used within the tran<strong>sport</strong> sector for determining route distances are<br />

not successful in accurately describing route distance when walking or bicycling for commuting purposes. By using correction factors, the<br />

deviations in mean values from the corresponding values obtained by the criterion method, can be neutralized. However, on the individual<br />

level, deviances from the correct value will still exist. This problem exists for all methods, but it is particularly evident for the selfreported<br />

data. Therefore, when there is need for distance values for analytical purposes, for example in a scientific context, the criterion<br />

method (Schantz & Stigell 2009) is recommended.<br />

INCREASING PHYSICAL ACTIVITY AND IDENTIFYING REASONS FOR INCATIVITY - A REVIEW<br />

ROVIO, E., LINTUNEN, T., HAVAS, E.<br />

LIKES RESEARCH CENTER, JYVÄSKYLÄ, FINLAND<br />

Introduction: The aim <strong>of</strong> this poster is to (1) evaluate intervention studies aiming at increasing physical activity and (2) suggest new approaches<br />

to the study <strong>of</strong> physical inactivity and behavioral change from the sociological and social psychological points <strong>of</strong> view. Most <strong>of</strong><br />

the people in the developed countries are not sufficiently physically active for physical activity to have a beneficial effects on their health. In<br />

addition, physical inactivity decreases productivity in the work place, causes workplace absenteeism and has significant effect on social<br />

and health care costs.<br />

Methods: A review <strong>of</strong> the current literature and earlier physical activity intervention studies.<br />

Results: Researchers have used a wide variety <strong>of</strong> interventions to stimulate increased physical activity (Biddle & Mutrie, 2008). Informational<br />

approaches aim at increasing knowledge and changing attitudes, while behavioral and social approaches aim at teaching behavioral<br />

management skills and at creating facilitative social environments. Environmental and policy approaches in turn aim at building a<br />

safe and attractive structure for physical activity (e.g., on the institutional/legislative level through changing organizational regulations,<br />

policies, and laws). Targets <strong>of</strong> interventions have been individuals, groups and communities (e.g., school, workplace). In general, it is<br />

relatively easy to increase physical activity in the short term, but not permanently (Biddle & Mutrie, 2008). Strategies that would be successful<br />

in enhancing physical activity have been hard to determine.<br />
