      <subfield code="a">Fifteen young subjects participated in the study. They were required to assume a staggered upright posture with left leg leading in front of a 75 por 75 cm raking box with 20-cm deep evenly distributed dry and wet sand and dirt. The subjects raked using a pulling and pushing action and a 60 cm stroke length at a self-selected optimum pace with a normal straight handled rake and with a rake with a modified handle. On the basis of the results of this study, the normal rake was concluded to be a better rake</subfield>
