Journal Title: Medycyna Sportowa - Year 2011, Vol 27, Issue 4
Abstract
[b]Background.[/b] The aim of the study was to present the practical using of pedometer in everyday life to plan own physical activity.[b]Material and methods.[/b] 33 adult men aged 45-64 years old (the average age: 51.53± 6.24 years) citizens of Lodz were subjected to the study. Before the study there were conducted the basic anthropometric measurements, which were used to count body mass index BMI. Physical activity and energy expenditure were measured by pedometer Yamax Digi-Walker SW-700, which has step counter, distance counter and calories counter, which count the energy expenditure on physical activity. Every man was obliged to wear the pedometer for 7 days all the time excepting the time for sleep. [b]Results.[/b] The average amount of steps was 6147 steps/day (±4246 steps/day) and energy expenditure 259.75 kcal/day (±196.84 kcal/day). Consequently, the energy expenditure necessary to do one step is 0,04 kcal. The higher person’s BMI (the average BMI in the sample: 28.62±6.69 kg/m2), the higher energy expenditure. However, energy expenditure necessary for one step did not exceed 0.06 kcal.[b]Conclusions. [/b]The average energy expenditure produced during 1 step is between 0.04 and 0.06 kcal (±0.014 kcal). According to that, to burn 1 kcal it is necessary to do about 23 steps. The recommended daily number of steps is 10 000 steps/day, so energy expenditure on the level of 400 to 600 kcal/day (±141.42 kcal/day).
