RESUMO

Resistance training represents group of means that seeks to the development and maintenance of components of physical fitness related with to the muscle-joint structures, mainly strength and local muscular endurance. The practice of this activity may cause the occurrence of microinjuries in the muscle fibers and delayed onset muscular soreness (DOMS), especially in beginners. During this phase adequate progression of the workload is necessary to avoid lesion or ailment. The present study aimed to compare two methods oftraining in relation to the appearence of creatine kinase (CK) in the bloodstream and DOMS. Differences in these parameters related to the rest periods and alternation of the muscular groups were studied. For the study groups ofUNlCAMP students were used 40 individuaIs were divided into two training groups, one using the multiple set system (MSS) and other performing circuit weight training (CWT). DOMS was evaluated according to the proposal ofTalag (1973) using specific protocol at the first opportunity on the day of training and during the three successive days following the training. Blood measurements were evaluated during the same period. CK levels in the blood were measured by espectrophotometer (Reflotron). ln order to participate in the research, the students previously answered the PAR-Q questionnaire to allow medical direction, weight, height and skinfolds were then measured. AlI the procedures had approval of the research ethics committee of the School of Medical ScienceslUNICAMP and the participants agreed to take part in the activities. After the fonnal consent, tests for individual workloads were applied and the Mann-Withney test was used to compar( the preliminary results from the training. The resuIts showed that CWT is less damaging, pointing to its use in the initial phases of training. In addition, the protocol used suggested a metabolic causal relationship between the exercise and the signs of muscular microinjury
