Resumen
The use of the bicycle as a means of transport is considered a sustainable and
healthy behavior. However, little is known about the characteristic of physical
effort employed by individuals during their usual paths. Therefore, this study
sought to characterize the physical effort performed by individuals who use the
bicycle as a means of transportation in urban environments during their usual
routes. In addition, it was analyzed whether the physical effort employed during
these routes would be enough to reach the recommendations of physical activity
for health promotion. Twenty adults (22-42 years old) who use the bicycle as a
means of transport (≥ 3 days/week) were monitored for seven days in their usual
routes using a Global Positioning System (GPS) with heart rate monitor (FC). We
analyzed: (i) distance traveled; (ii) duration and slope of the course; (iii) speed of
travel; and (iv) time spent on light exertion intensity (<64% HRmax), moderate
(64-76% HRmax) and vigorous (> 76% of HRmax). The data are described in
average and 25th and 75th percentiles. The individuals covered a distance of 3.8
km (2.6-5.9 km) per course in 13.1 min (10.6 - 20.9 min) with Average elevation
of 30.1 m (16.2 - 70.9 m) at an average speed of 16.9 km / h (14 - 17.8 km/h). The
time spent on mild exertion was 19.9% (12.6 - 29.3%), moderated 46.1% (40.9 -
54.4%) and vigorous 29.9% (12.5 - 44, 9%). Considering the total volume of
routes performed during the week, 50% of the sample (n = 10) reached the
recommendations of physical activity for health promotion (at least 150 min of
moderate-vigorous physical activity) only using the bicycle as a means of transportation. We conclude that the physical effort performed by individuals who
use the bicycle as a means of transportation in urban areas is predominantly
moderate-vigorous. Therefore, besides being a sustainable option, the use of the
bicycle as a means of transportation seems to be an interesting alternative to reach
the recommendations of physical activity for health promotion.
