Physical activity when riding an electric-assisted bicycle with and without cargo
Background: Regular physical activity provides several health benefits, and active transport is a convenient way to implement physical activity in everyday life. However, bikes’ lack of possibilities to carry cargo is a limitation. E-cargo bikes can help overcome barriers to cycling and increase levels of active transport while still providing the option to carry cargo such as groceries and children. As such, E-cargo bikes have a greater potential for being a substitute for cars, but relevance is not known as no study has assessed the energy expenditure and time used using E-cargo bikes with considerable cargo. Objectives: The aim of this study is to compare time spent riding and exercise intensity when (1) riding an electric-assisted bicycle with cargo (30 kg) and without cargo and (2) driving a car. Method: This study has a randomised crossover design. Eleven participants (six women) were recruited through convenience sampling. The participants traversed through a 4.5 km route with three different forms of transportation: an electricassisted bicycle (E-bike) with 30 kg cargo, an E-bike without cargo, and a car. Oxygen uptake was measured with a portable oxygen analyser (Metamax 3B), and time spent cycling was measured on site by the test leader using a stopwatch. Results: Riding an E-bike with cargo was slightly slower than riding an E-bike without cargo (11.8 vs. 11.1 min, p = 0.017) and driving a car (8.8 min, p = 0.002). There was no significant difference in exercise intensity between E-bikes with and without cargo but riding an E-bike with cargo entailed significantly higher exercise intensity compared to driving a car [4.9 metabolic equivalents of task (METs) vs. 1.4 METs, p ≤ 0.001]. Conclusions: E-biking with cargo was rather similar in time spent and exercise intensity to E-biking without cargo, and not much slower than driving a car. Using E-cargo bikes, therefore, appears a good alternative to driving a car when in need of carrying things such as grocery bags and children, resulting in increasing physical activity and, at the same time, decreasing greenhouse gas emissions.publishedVersio

The effects of subsidising e-bikes on mode share and physical activity - A natural experiment
Hanne Beate Sundfør, Sveinung Berntsen, Elling Tufte Bere, Aslak Fyhri, The effects of subsidising e-bikes on mode share and physical activity - A natural experiment, Journal of Transport & Health, Volume 35, 2024, 101752, ISSN 2214-1405, https://doi.org/10.1016/j.jth.2023.101752. (https://www.sciencedirect.com/science/article/pii/S2214140523001895)Introduction The promotion of increased cycling is a political goal in numerous countries due to its environmental and public health benefits. Initiatives to stimulate e-bike use, like subsidies, may be a relevant strategy. However, understanding of the effects of these subsidies remains limited. In the present study our aim was to investigate the short-term effects of subsidising e-bike purchases on mode share distribution, physical activity derived from daily travel, and overall levels of physical activity. Methods We used the 2020-subvention program in Oslo, Norway, as a natural experiment, employing a pre-post randomised group design. The trial group (N = 194) and control group (N = 2174) participated in a survey at two time points (in April and September 2021), which included a one-day travel diary and questions about physical activity over the previous week. Results Our findings revealed a significant 12.6 [7.2, 18.0] percentage point increase in bicycle mode share, followed by a decrease in the share of car and public transport usage of 10.1 [-15.9, −2.5] and 7.1 [-11.8, −2.4] percentage points. In terms of physical activity generated from daily travel, we observed a greater increase in e-cycling compared to the decrease in conventional cycling and walking, resulting in an overall rise in active transport. However, despite these findings, we did not detect a significant increase in overall physical activity resulting from this increased active mobility. Conclusion Initiatives such as subsidies for e-bikes may align with both environmental and public health goals, as the subvention led to an increase in the bicycle mode share and an overall rise in active transport. However, to assess the impact on overall physical activity, additional research utilising more precise measurements is needed.The effects of subsidising e-bikes on mode share and physical activity - A natural experimentpublishedVersio

Ultraprosessert mat burde være et kostråd: JA
Nøkkelpunkter
• Det er konsistente, sterke sammenhenger mellom høyt inntak av UPF og en rekke
livsstilssykdommer.
• Det er uhelse igjen i UPF etter at sukker, salt, fett, fiber og andre kostholdsmønstre
er justert bort.
• Det at enkelte «sunne» matvarer har fått preg av industriell ultraprosessering bør pirre
nysgjerrigheten og sette oss i føre-var modus, heller enn å avfeie UPF-klassifiseringen.
• UPF er tydelig definert innenfor NOVA-klassifiseringen – NNR bruker mer utydelige begrep som «prosessert» eller «plantebasert».
• Vi mener NNR-rapporten viser et reduksjonistisk syn på mat og helse – ordet evolusjon nevnes ikke ett eneste sted.publishedVersionPaid open acces
