Changes in stature during physical activity reflect alterations in spinal column length that occur as a result of loading the spine. The shrinkage is associated with loss of intervertebral disc height. This study aimed to measure both the load on the spine during simulations of a round of golf and the physiological responses to carrying golf clubs. Fine measurement of stature was achieved using a computer‐linked stadiometer inclined to 13°. Shrinkage was measured (n = 6) after performance regimens which mimicked (1) the ambulatory activity during golf play, (2) ambulation and skills employed in par performance and (3) ambulation and carriage of clubs. Our observations indicate significant shrinkage associated with golf skills, mean shrinkage after nine holes being 2.53 mm compared to 1.78 mm in the walking condition. The highest shrinkage was observed when the player carried his clubs, the amount of stature loss being 4.76 mm over nine holes. The highest rates of shrinkage occurred over the first three holes. In a second experiment to further examine the effects of carrying the golf clubs, five of the subjects walked on a motor‐driven treadmill at 5 km h^‐1 for 5 min. Carrying the clubs caused a 15% increase in VO₂ and a 25% rise in VE compared to normal walking. Increases were found also in perceived exertion. The physical and physiological loadings associated with recreational golf were deemed to be light to moderate and do not denote undue strain in occasional practices.     

The Extern Program: An Approach to Counselor Renewal

Counselor education programs must respond to the need for inservice education for practicing, school counselors. The Extern Program described here is designed to provide inservice education through didactic, experiential learning activities implemented on a one weekend per month schedule for nine months. The weekend training involves new developments in the field of counseling, problem solving with a focus on concerns brought to the sessions by the counselors, and new developments in the behavioral sciences outside education. Each weekend is divided into eight phases as follows: (1) didactic input with the topic related to the field of counseling; (2) synthesis and discussion of didactic input with small-group interaction; (3) participant problem solving with small-group interaction; (4) group problem solving with large-group discussion and synthesis; (5) didactic input with the topic relevant to counselor education; (6) synthesis and discussion of didactic input with small group interaction; (7) didactic input with the topic being behavioral science developments outside education; and (8) synthesis and discussion of didactic input with small-group interaction. An evaluation plan is also discussed.
