Many exercise protocols are in use in clinical cardiology, but no single test is applicable to the wide range of patients' exercise capacity. A new protocol was devised that starts at a low workload and increases by 15% of the previous workload every minute. This is the first protocol to be based on exponential rather than linear increments in workload. The new protocol (standardised exponentia...
INTRODUCTION Active commuting - walking and bicycling for travel to and/or from work or educational addresses - may facilitate daily, routine physical activity. Several studies have investigated the relationship between active commuting and commuting stress; however, there are no studies examining the relationship between solely bicycle commuting and perceived stress, or studies that account fo...
OBJECTIVE Females are substantially less likely than males to cycle for transport in countries with low bicycle transport mode share. We investigated whether female commuter cyclists were more likely to use bicycle routes that provide separation from motor vehicle traffic. METHODS Census of cyclists observed at 15 locations (including off-road bicycle paths, on-road lanes and roads with no bi...
Purpose – The purpose of this paper is to provide information on the activities of police bicycle patrols. Design/methodology/approach – A participant/observation research design was used. A five-city, 32-shift study on the output of police bicycle patrols was conducted. Same and similar ride-alongs were conducted with bicycle and automobile patrols. All contacts (n 1⁄4 1,105) with the public w...
OBJECTIVE This paper examines the relationship between bicycle collisions and the amount of cycling at the local level. Most previous research has focused on national and city comparisons, little is known about differences within a city (the mesoscale). METHODS This study mainly used three types of data sets relating to bicycle collisions, use of bicycles and local neighbourhood characteristi...
Proper bicycle fit is very important for cycling performance, efficiency, comfort and injury prevention. This is especially true in the case of children cyclists that do not have the necessary cycling experience, balance and the fully developed musculoskeletal system of the adults. Bicycle fit depends on both the design and dimensions of the bicycle as well as on the anthropometric dimensions o...
OBJECTIVE To determine why people do or do not wear helmets while bicycling. METHODS A survey was conducted from August through October 1999. Two survey areas were chosen for this study: local public schools and paved bicycle trails. For the school arm of the study, 3 public elementary, middle, and high schools were selected from 3 different regions of Rochester, Minnesota, for participation ...
