Abstract
This study examines the validity of the ACSM prediction equation for estimating oxygen consumption during submaximal cycling in aerobically trained males. The alternate hypothesis of this study is that the estimated vs. actual VO2 during submaximal cycle ergometry would be similar from 50-200 W. A secondary focus analyzes and compares the accuracy of the equation between two distinct groups of subjects (trained male cyclists vs. aerobically-trained male non-cyclists).

"The results of this study suggest that the ACSM cycle ergometry prediction equation is most accurate at moderate workloads (~100-150 W). Furthermore, training status has no effect on the predictive value of the equation. Further studies on the effects of training habitus should be fashioned to include a larger sample with greater distinction in training volume, i.e. cycle ~200 miles/week vs. sedentary. Based on the current sample size, subtle differences are very difficult to observe. However, this study provides a strong basis for the direction of future research in this area."

Abstract
This paper first relates that the purpose of exercise can vary widely for an individual and that these variations determine the type (cardiovascular, resistance, etc...), the duration, frequency, and intensity of the exercises. The paper then describes an overall training program composed to improve aspects typically associated with an elite road cyclist with a high baseline fitness level, with a 2 month period specifically dedicated towards individual pursuit training (specifically the skill aspects of individual pursuit). The paper also proposes an exercise training program consisting of four separate macrocycles. Two tables and three graphs are included with the paper.

Conclusion

From the Paper
"Injury is a constant threat to any exercise training programme. Due to the nature of the sport (cycling) the likelihood of injury is less common, however, as more training and racing occurs, patterns of overuse injury become evident (So, Ng and Ng 2005). There is limited research available that looks at the association between weekly training duration and injury occurrence for individual pursuit, although there is evidence available for a closely related sport (triathlons). The evidence suggests there is a U-shaped association between weekly training duration and injury occurrence, where the optimal weekly training duration is 7 hours (Shaw et al. 2004). It can be assumed that same association could exist for cycling. If this association exists, the optimal weekly training duration would be higher, because cycling is non-impact activity. For this reason, this exercise training programme would have a weekly training duration of no more than double that of the optimal weekly training duration of triathletes, 14 hours.

Abstract
The paper argues that in certain cases, environments which are safe for pedestrians and bicycle commuters have healthier populations but this is not necessarily always true. The paper asserts that if a person is walking, bicycling or exercising in open spaces during times of heavy smog, for instance, they will not benefit and may be harming themselves, but when environments are safe, pedestrians and cyclists are free from the danger of injury or death and can enjoy the benefits of exercise for health and for simple recreation. The paper asserts that the key is having sufficient numbers of people involved in walking and cycling because this will reduce vehicle accidents and pollution. The paper relates that city planners and the public in cities around the world are now aware that walking and cycling results in a very healthy population compared to those people who do not use outdoor exercise.
