- Abstract
The purpose of the study was to compare blood creatine kinase (CK) concentration of 15 physically active healthy male after one and two-legged cycling. After the procedures were explained, the subjects went to the laboratory on four occasions. The first was a familiarization session. During sessions 2, 3 and 4, the subjects performed one and two-legged maximal tests that were separated by 48 to 72 hrs. A blood sample was taken before and 24 hrs after each test to determine blood CK responses. After the twolegged exercise, blood CK responses (7.14 ± 201.87 U/l) were significantly lower (P<0.05) compared to the right (138.87 ± 155.57 U/l) and the left leg responses (126.17 ± 115.02 U/l). When ΔCK was related to work load, the two-legged protocol led to lower increases (0.07 ± 0.78 ΔCK/W) compared to the right and left legs (1.69 ± 1.53 ΔCK/W and 1.75 ± 1.64 ΔCK/W, respectively). The present study shows that one-legged cycling exercise leads to great increases in blood CK of physically active men after 24 hrs.
