Quadrupedal running on grades requires balancing of pitch moments about the center of mass (COM) while supplying sufficient impulse to maintain a steady uphill or downhill velocity. Here, trotting mechanics on a 15 deg grade were characterized by the distribution of impulse between the limbs and the angle of resultant impulse at each limb. Anterior-posterior manipulation of COM position has pre...

In trotting dogs, the pattern of activity of the obliquely oriented hypaxial muscles is consistent with the possible functions of (i) stabilization against vertical accelerations that cause the trunk to sag in the sagittal plane and (ii) stabilization against forces that tend to shear the trunk in the sagittal plane. To test these hypotheses, we compared the amount of activity of the intercosta...

A 37 year old recreational long distance triathlete complained of right leg pain during running since early 2002. The problems mainly occurred when running uphill, with a cramp-like pain and tightness in the anterior and lateral aspect of the right lower leg, associated with a loss of power and numbness in the foot. After periods of rest and treatment with physiotherapy, acupuncture and nutriti...

PURPOSE The purpose of the present study was to examine relationships between athlete's pacing strategies and running performance during an international triathlon competition. METHODS Running split times for each of the 107 finishers of the 2009 European Triathlon Championships (42 females and 65 males) were determined with the use of a digital synchronized video analysis system. Five camera...
