The Effect of Short-Term and Interval Periods of Active and Passive Recovery on Blood Lactate, Lactate Dehydrogenase (LDH) and Creatine Phosphokinase (CPK) Levels in Male Rock-Climbers in Borujerd

The superiority of continuous active recovery on passive recovery has been completely specified. However, the time needed for such recovery is (20-60 minutes) and its intensity is not well controlled. One the other hand, after the majority of short-term exercises, a short-term recovery is need to return the athlete promptly to normal condition to have better performance. But, this type of recovery is not completely known in terms of duration, intensity and type of activity. The objective of the present study is to investigate the effect of short-term recovery (3 min) in replicated rockclimbing activities on blood lactate, LDH and CPK concentration of elite male rock-climbers. For this purpose, 10 elite male rock-climbers (age: 24±2.92 years, weight: 60±6.19 kg, height: 173±5.73 cm and BMI: 19±2.98) voluntarily participated in this study. Rock-climbers participated in a cross over study with an interval of 5 days in two trials, including four 2 min climbing activities with 3 min of passive recovery after each activity in the first experiment and 3 min of active recovery after each activity in the second experiment.In the case of active recovery, the subject ran on a treadmill with an intensity of 45% VO2Max. Before each climb, two additional minutes were considered for blood sampling. The blood samples were taken from auricle vessels for measuring lactate level. Forearm venous blood samples were taken in each period for measuring LDH and CPK levels. Blood samples were taken before the first climb and immediately after each recovery period. The results showed a significant difference between active and passive recovery in terms of lactate and LDH (P <0.005) and CPK levels (P <0.039). Regarding this investigation, after each period of active recovery, the rock-climbers began the next climb with lower levels of lactate, LDH and CPK compared with passive recovery.
