Abstract

This paper describes a new six-load component pedal dynamometer designed for study of knee overuse injury in cycling. A unique capability of the dynamometer is the ability to interface with multiple pedal platforms of varying height while maintaining a desired elevation of the foot above the pedal spindle axis. The dynamometer was designed using a concept described in an earlier article by Quinn and Mote (1991, Exp. Mech. 30, 40-48) which measures shear strain across multiple, thin cross-sections. An optimal design technique was used for choosing dimensions of the load measuring cross-sections. A dynamometer was designed and built using the optimal results. Calibration, accuracy results, and sample data are presented. A comparison of accuracy reveals that the new dynamometer is more accurate than previously reported instruments.

The physiology of mountain biking.

Mountain biking is a popular outdoor recreational activity and an Olympic sport. Cross-country circuit races have a winning time of approximately equal 120 minutes and are performed at an average heart rate close to 90% of the maximum, corresponding to 84% of maximum oxygen uptake (VO2max). More than 80% of race time is spent above the lactate threshold. This very high exercise intensity is related to the fast starting phase of the race; the several climbs, forcing off-road cyclists to expend most of their effort going against gravity; greater rolling resistance; and the isometric contractions of arm and leg muscles necessary for bike handling and stabilisation. Because of the high power output (up to 500W) required during steep climbing and at the start of the race, anaerobic energy metabolism is also likely to be a factor of off-road cycling and deserves further investigation. Mountain bikers' physiological characteristics indicate that aerobic power (VO2max >70 mL/kg/min) and the ability to sustain high work rates for prolonged periods of time are prerequisites for competing at a high level in off-road cycling events. The anthropometric characteristics of mountain bikers are similar to climbers and all-terrain road cyclists. Various parameters of aerobic fitness are correlated to cross-country performance, suggesting that these tests are valid for the physiological assessment of competitive mountain bikers, especially when normalised to body mass. Factors other than aerobic power and capacity might influence off-road cycling performance and require further investigation. These include off-road cycling economy, anaerobic power and capacity, technical ability and pre-exercise nutritional strategies.

Pedal-cycle injuries among children aged <6 years--Wisconsin, 2002-2004.

Measures to improve pedal-cycle safety and increase helmet use often target school-age children rather than younger children, even though preschool children wearing helmets have fewer injuries and are more likely to wear helmets in the future, compared with children who do not wear helmets. Children aged <6 years also use pedal cycles; whether they are passengers on a parent's bicycle, riding a tricycle or pedal car, or learning to ride a bicycle, these young cyclists often sustain injuries. To provide guidance for intervention strategies targeted to young children in Wisconsin, CDC and the Wisconsin Division of Public Health analyzed data collected from January 1, 2002 through December 31, 2004, from all nonfederal emergency departments (EDs) and hospitals in Wisconsin regarding pedal-cycle injuries among children aged <6 years. This report describes the results of that analysis, which indicated that, during 2002--2004, a total of 2,046 ED visits by Wisconsin residents aged <6 years for pedal-cycle injuries occurred; for 1,305 (63.8%) of these visits, the primary diagnosis was a head or neck injury. These findings underscore the need for interventions designed to reduce head and neck injuries in the youngest users of pedal cycles.
