Pacing

1) Determining Pace Factor. A) Select a straight and level course and on both ends establish markers at least 50 meters apart. Designate these endpoints as A and B. B) Walk over the course at a natural pace or gait starting with either heel or toe over point A and count the number of paces to reach point B. C) For succeeding tn'als, walk from B to A. then A to B, until 6 trials are completed. and the number of paces is recorded accordingly. D) Tabulate. E) To compute for the pace factor. get the average of the number of paces and then divide this to the taped length of course AB. 2) Measuring Distance by Pacing A) Dene or establish the endpoints of another level course whose length is to be determined by pacing. Designate these endpoints as C and D. B) For the rst trial. watk over the course from C to D at a natural pace and record the number of paces. Then walk from D to C and again record the number of paces. C) Repeat the above procedure until all ve trials are completed. D) After the eld data recorded, make an actual taping of the course CD to determine the taped distance. 3. Computing the Accuracy of their Pace Factor A) Compute the Percent Error using the formula: XS |x1oo x = measured distance 3 = taped distance % Error - I % Accuracy= 100- %Error 4. Computing the Linear Regression A) Complete the table below. TRIAL LINE NO. OF PACED TAPED PACE DISTANCE rn DISTANCE m B) Formulate the y=mx + b equation by using the number of trials as x values and paced distance as y values. 5. Computing the Pearson Correlation Factor Using the discussed formula of the Pearson Correlation Factor and the data from the table above, compute the correlation factors R and R2 and discuss the outcome
