The positive health benefits of regular exercise, particularly regarding cardiovascular risk and diseases, are well recognized and scientifically evident. However, a sedentary lifestyle is one of the most important cardiovascular risk factors that are still insufficiently addressed. Leisure-time active commuting like walking and biking is an ideal way to improve exercise behavior in the general population. The purpose of this substudy of the GISMO study was to assess dose-response relations in all commuters and the three subgroups of commuters (physically active by bicycle and/or walking, physically active by using public transportation (PT), and the controls using their own vehicles). As such, a positive dose-response relationship could be confirmed in all physically active commuters compared to the control group. Whether the commuters cycled, walked, or traveled by PT -the more the physical exercise they performed (measured in metabolic equivalent [MET]-hours), the larger their gain in physical fitness (measured in gained or "Delta" Watt during a maximal exercise test), and their physical fitness at the end of the study was P = .016 and P = .003, respectively. Health-related quality of life correlated in two out of eight subdomains of the SF-36 questionnaire with MET-hours achieved during the study period (General Health and Physical Functioning). No clearly significant dose-response could be observed regarding HDL(high-density lipoprotein)-cholesterol or body composition. Our results indicate a dose-response pattern of healthy commuting in exercise capacity and health-related quality of life to increase doses of physically active commuting., (© 2020 John Wiley & Sons A/S.

Sedentary lifestyle is a major modifiable risk factor for many chronic diseases. Global guidelines recommend for maintaining health in adults, at least 150 minutes of moderate intensity of physical activity throughout the week, but compliance is insufficient and health problems arise. One obvious way to overcome this is to integrate physical activity into the daily routine for example by active commuting to work. Scientific evidence, however, is scarce and therefore we set out to perform this systematic review of the available literature to improve understanding of the efficiency of active commuting initiatives on health. Literature searches were performed in PubMed and Cochrane database. Altogether, 37 studies were screened. Thereof, eight publications were reviewed, which included 555 participants. The mean study duration of the reviewed research was 36 ± 26 (8-72) weeks. Overall, active commuting in previously untrained subjects of both sexes significantly improved exercise capacity, maximal power, blood pressure, lipid parameters including cholesterol, high-density lipoprotein, and waist circumference. Improvement was independent of the type of active commuting. Despite relatively few studies that were previously performed, this review revealed that active commuting has health beneficial effects comparable to those of moderate exercise training., (© 2020 John Wiley & Sons A/S.

Increased physical activity is associated with numerous health benefits. This study investigated the effect of active commuting (walking and cycling to work) on health-related quality of life (HRQoL) and absence days from work due to sickness in healthy working adults. In total, 73 participants (age: 46 ± 9 years), all working at a tertiary university hospital in Salzburg, Austria, were randomized into an intervention group (IG, n = 51) and a control group (CG, n = 22). The IG was asked to commute actively for twelve months, whereas the CG did not have to change their usual commuting behavior. IG was divided into two subgroups: IG-C (cycling, n = 26) was asked to commute by bicycle and IG-PT (public transport, n = 25) partially using public transportation and walked the remaining distance to work. Significant positive changes in IG were observed in four subcomponents of the SF-36 (physical functioning (95 [10] to 100 [8.8], P = .023), mental health (82 [15] to 86 [15], P = .036), vitality (65 [20] to 70 [14], P = .005), and general health (70 [19] to 80 [24], P = .004)) as well as the physical component summary score (56.5 [9] to 59.2 [6.3], P = .002). IG-C showed greater and more statistically significant changes regarding HRQoL compared to IG-PT. Associations between active commuting and sick-leave days were only observed in IG-PT (7.5 [14.8] to 4.0 [11.3] days, P = .038). In conclusion, active commuting improves various components of HRQoL and might therefore be a possible strategy to increase quality of life in the workforce., (© 2020 John Wiley & Sons A/S.

Active commuting has the potential to decrease cardiovascular risk by increasing physical activity. We aimed to investigate the effects of active commuting to work for 12 months on body composition and cardiovascular risk factors. Therefore, 73 hospital employees (age: 46 ± 9 years, 36% males), with a predominantly passive way of commuting, were randomly assigned to an intervention group (IG) and a control group (CG) in a 2:1 fashion. The IG was further divided into a public transportation plus active commuting group (IG-PT) and a cycling group (IG-C). Both IGs were prompted to reach 150 min/wk of moderate intensity exercise. Daily self-reported commuting details were verified by GPS tracking. All subjects underwent assessment of body composition, resting blood pressure, glycemic control, and lipid profile at the beginning and end of the study. Data for final analyses were available in 62 subjects. Commuting details indicated that the subjects randomized to IG changed their commuting habits. HbA1c decreased by 0.2% [95%CI: -0.3, -0.2] in IG-PT but was not statistically different between groups (P = .06). LDL cholesterol decreased in IG-C by 0.8 mmol/L [-1.1, -0.4] and by 0.6 mmol/L [-1.2, 0.1] in IG-PT which can be considered biologically relevant but did not yield statistical significance. Body composition and blood pressure did not differ between groups. Active commuting to work for 12 months did not change body composition but yielded relevant changes in lipid profile and glycemic control. Health benefits of active commuting should be addressed by healthcare professionals when counseling individuals that seek to improve their cardiovascular risk profile., (© 2020 The Authors.

A sedentary lifestyle is a major modifiable risk factor for many chronic diseases. Lifestyle modification in order to increase exercise capacity is key in the prevention and rehabilitation of chronic diseases. This could be achieved by active commute. The aim of this study was to assess the effects of daily active commuting on physical activity (PA) and exercise capacity. Seventy-three healthy hospital employees (age: 46 ± 9 years, 38% male), with a predominantly passive way of commuting, were randomly assigned to two parallel groups, a control group (CG, N = 22) or an intervention group (IG, N = 51), which was further split into public transportation/active commuting (IG-PT, N = 25) and cycling (IG-C, N = 26). Both intervention groups were asked to reach 150 min/wk of moderate- to vigorous-intensity exercise during their commute for 1 year. CG maintained a passive commuting mode. All participants underwent assessment of anthropometry, risk factor stratification, and exercise capacity by a medical doctor at the Institute of Sports Medicine, Prevention and Rehabilitation. Weekly physical activity, using the International Physical Activity Questionnaire and commuting behavior, using an online diary, were used to assess physical activity. At the end of the study, the change in exercise capacity did significantly differ between IG and CG (P = .003, ES = 0.82). Actively covered distances through commuting significantly differed between groups (walking P = .026; cycling P < .001). Therefore, active commuting improves exercise capacity and can be recommended to the working population to increase exercise capacity., (© 2020 The Authors.
