Abstract
- The present investigation aimed to establish whether noncompetitive rock climbing fulfills sports medicine recommendations for maintaining a good level of aerobic fitness. The physiological profile of 13 rock climbers, 8 men (age, 43 [+ or -] 8 years) and 5 women (age, 31 [+ or -] 8 years) was assessed by means of laboratory tests. Maximal aerobic power (Vpo.sub.2]peak) and ventilatory threshold (VT) were assessed using a cycloergometer incremental test. During outdoor rock face climbing, V[o.sub.2] and heart rate (HR) were measured with a portable metabolimeter and the relative steadystate values (V[o.sub.2] and HR during rock climbing) were computed. Blood lactate was measured during recovery. All data are presented as mean [+ or -] SD. V[o.sub.2] peak was 39.1 [+ or -] 4.3 mL.[kg.sup.-1].[min.sup-1] in men and 39.7 [+ or -] 5 mL.[kg.sup.-1].[min.sup.-1] in women, while VT was 29.4 [+ or -] 3.0 mL.[kg.sup.-1].[min.sup.-1] in men and 28.8 [+ or -] 4.6 mL.[kg.sup.-1].[min.sup.-1] in women. The V[o.sub.2] during rock climbing was 28.3 [+ or -] 1.5 mL.[kg.sup.-1].[min.sup.-1] in men and 27.5 [+ or -] 3.7 mL.[kg.sup.-1] .[min .sup.-1 ]in women. The HR during rock climbing was 144 [+ or -] 16 b.[min.sup.-1 in men and 164 [+ or -] 13 b.[min.sup.-1] in women. The aerobic profile was classified from excellent to superior in accordance with the standards of the American College of Sports Medicine (ACSM). The exercise intensity V[o.sub.2] during rock climbing expressed as a percentage of V[o.sub.2]peak) was 70 [+ or -] 6% in men and 72 [+ or -] 8% in women. Moreover, the energy expenditure was 1000-1500 kcal per week. In conclusion, noncompetitive rock climbing has proved to be a typical aerobic activity. The intensity of exercise is comparable to that recommended by the American College of Sports Medicine to maintain good cardiorespiratory fitness.
