The effect of mountain bike wheel size on cross-country performance.
The purpose of this study was to determine the influence of different wheel size diameters on indicators of cross-country mountain bike time trial performance. Nine competitive male mountain bikers (age 34.7 ± 10.7 years; stature 177.7 ± 5.6 cm; body mass 73.2 ± 8.6 kg) performed 1 lap of a 3.48 km mountain bike (MTB) course as fast as possible on 26″, 27.5″ and 29″ wheeled MTB. Time (s), mean ...
متن کاملDynamics of Progression in Mountain Bike Racing
A major tenet of the recreation specialization framework is that people progress to higher stages of involvement over time. Results from recent studies suggest that involvement may actually be marked by stability or decline. Little is known about the extent to which people progress in outdoor activities where objective standards of performance exist. The purpose of this study was to examine the...
متن کاملA bike-wheel microcell for measurement of thin-film forces
A thin-film balance employing either a Sheludko capillary or a Mysels-inspired porous-medium film holder provides a direct measurement of disjoining-pressure isotherms in free, liquid thin films. However, each film holder suffers its own distinct disadvantages spanning non-uniform and slow liquid exchange, a limited range of measurable disjoining pressures, an inability for reuse, and a require...
متن کاملExtreme mountain bike challenges may induce sub-clinical myocardial damage.
AIM The relationship between extreme exercise and coronary artery disease is not well understood, and the information available is contradictory. The aim of the present study was to determine whether strenuous endurance exercise, performed under conditions in which the partial pressure of environmental oxygen varies constantly, can induce myocardial cell injury. METHODS Plasma urea, creatinin...
متن کاملNutrition habits in 24-hour mountain bike racers
We investigated seventy-four ultra-mountain bikers (MTBers) competing in the solo category in the first descriptive field study to detail nutrition habits and the most common food before during and after the 24 hour race using questionnaires. During the race, bananas (86.5%), energy bars (50.0%), apples (43.2%) and cheese (43.2%) were the most commonly consumed food, followed by bread (44.6%), ...
