The recently developed CROSS WALKR exercise treadmill incorporates resistive arm poles designed to increase the metabolic costs associated with walking. Twenty-nine healthy men (mean age, 24.2 yr) were recruited to study the physiological effects of utilizing the arm poles during normal treadmill walking at 2,3, and 4 mph at a 3% grade. Ss walked at each test speed for 5 min with arms and 5 rnin without arms, achieving steady state HR and VO, at each of the 6 stages. The arm poles increased VO, (ml-min-I) by an average 58% and HR by an average of 32% above normal walking. Using arm poles increased RPE to a much lesser degree (9.1%). Except for RER, the arm pole treatment produced significantly (p < .01) higher values for all remaining metabolic variables (V,, Lsmin-I, kcals, and METs). It was concluded that the CROSS WAL,KR's arm poles #lowed individuals to obtain higher exercise intensity levels during treadnr911 walking without corresponding increases in perceived cardiovascular strain.
