The purpose of this study was to evaluate fitness and health adaptations from a training program riding all-terrain vehicles (ATV) and off-road motorcycles (ORM) as the exercise stimulus.
The purpose of this study was to evaluate fitness and health adaptations from a training program riding all-terrain vehicles (ATV) and off-road motorcycles (ORM) as the exercise stimulus. Participants (n = 58) were randomized to a control group (n = 12) or one of four experimental groups; 2 days/week ATV (n = 11), 2 days/week ORM (n = 12), 4 days/week ATV (n = 11), or 4 days/week ORM (n = 12). Aerobic fitness, musculoskeletal fitness, body composition, clinical health, and quality of life (QOL) were compared at baseline and following 6 weeks of training. In all riding groups, there were improvements in blood pressure (SBP = 9.4 ± 10.1, DBP = 5.8 ± 6.2 mmHg), fasting glucose (0.5 ± 0.7 mmol/l), subcutaneous adiposity (0.9 ± 1.1%), body mass (0.7 ± 2.7 kg), waist circumference (1.3 ± 2.5 cm), and isometric leg endurance (26 ± 44 s). All changes were of moderate to large magnitude (Cohen’s d 0.52–0.94) with the exception of a small loss of body mass (Cohen’s d = 0.27). Although changes occurred in the riding groups for aerobic power (2.9 ± 4.6 ml kg-1 min-1), leg power (172 ± 486 w), and curl-ups (13.2 ± 22.7), these changes were not significantly different from the control group. No significant alterations occurred in resting heart rate, trunk flexibility, back endurance, hand grip strength, long jump, pull/push strength, or push-up ability as a result of training.
Physical domain QOL increased in all 2 days/week riders but mental domain QOL increased in all ORM, but not ATV riders regardless of volume. Ambient carbon monoxide levels while riding (\30 ppm) were within safe exposure guidelines. Positive adaptations can be gained from a training program using off-road vehicle riding as the exercise stimulus.

The phenomena of thru-hiking has been on a dramatic rise, spurring hikers to venture onto increasingly remote and challenging trails over extended periods of time. Despite the recent popularity of thru-hiking, the field remains relatively unstudied. In recreation, the expectations held beforehand have been linked to perceptions after an activity, but this has not been explored in thru-hiking.
This study evaluated pack weight to understand the limits of long-term load carriage. Participants were Appalachian Trail hikers who attempted to complete the entire trail in the 2012 season.
The purpose of this research was to examine the outcomes prompting hiking along the Appalachian Trail (AT).
In recent years, fat bikes have become a popular option for mountain bikers. A fat bike is a mountain bike equipped with tires ranging from 9.3 – 10.1 cm wide, twice as wide as a traditional mountain bike tire (Barber, 2014). This allows them to be ridden at an inflation pressure as low as 27579 Pascal (4 PSI). The wide surface area, and low inflation pressure, of these tires allows for excellent handling of the bicycle while riding over sand, mud, and snow. It is difficult, if not impossible, for a traditional mountain bike to ride over such surfaces.
