• To examine whole body running mechanics in female distance runners during a simulated 10 km race on a treadmill. Nine female distance runners (age: 32.1+ or -4.2yrs; ht: 166.7 + or - 7.4 cm ; wt: 57.8 + or - 7.0 kg; VO sub(2)max = 3.24 + or - 0.50 L/min) completed a graded exercise test (Day 1); 10 km time trial (Day 2); and simulated 10 km treadmill run (DAY 3). Treadmill speed was 95 % of average running velocity of the Day 2 time trial. Reflective markers were placed bi-laterally and kinematic data were sampled at 120Hz at 50 m (BASE), 4450 m (MID) and 9950 m (END) using a 6-camera optoelectronic motion capture system. Stride frequency decreased for both the left and right legs (BASE to MID by 1.27strides/min for both and by 1.66 strides/min from MID to END (p<0.05). Overall maximum knee flexion during swing phase increased for both the left and right legs (BASE to END by 4.3[degrees] (p>0.05).
