Effect of exercise order of resistance exercise on serum cellular damage enzymes in untrained men

 
Background and Objective: The exercise order refers to the sequence of resistance exercises in a training session. The objective of this study was to investigate the influence of different resistance exercise execution orders on the Creatine kinase (CK) and Lactate dehydrogenase (LDH) changes. Materials and Methods: For this aim, 20 untrained men were randomly assigned into two groups, with large and progressed toward small muscle group exercises (LSM; n-10) while another started with small and advanced to large muscle group exercises (SLM; n=10). LSM performed resistance exercise with bench press, lat pull down, triceps machine, and biceps barbell, respectively. SML performed exercises, inversely. Venous blood samples were drawn pre- exercise, immediately after the exercise, 24th and the 48th of post-exercise. Results: Results showed that in both group CK (P=0.001) and LDH (P=0.001) increase enzymes levels after 24 h exercise, and this increasing continued for 48 hr after exercise. However, there is no significant difference between resistance exercise xtime in any point time in CK and LDH (P>0.05). Conclusion: Generally, it can be said that exercise order of resistance exercise with large and progressed toward small muscle groups/ or inverse could not be main factor on cellular damage.
