Abstract
This study aimed to investigate the effect of two strength training methods on the development of some physiological variables among karate juniors. To achieve this, the researcher employed a quasi-experimental approach on a purposive sample consisting of 21 karate juniors in Palestine. The participants were equally divided into three training groups (Complex Training, Multi-sets, and traditional method). Pre- and post-tests were conducted for the physiological variables (anaerobic power, anaerobic capacity, creatine kinase, dehydrogenase, and testosterone). Data were analyzed using the SPSS statistical program. The results showed statistically significant differences between the pre- and post-tests for the physiological variables (anaerobic power and anaerobic capacity) in favor of the post-test for all three training groups. Additionally, there were statistically significant differences in the post-test for the physiological variables (anaerobic power, anaerobic capacity, and testosterone) between the three training groups. The researcher recommends conducting similar studies on females, as well as in different age groups and for both genders. In addition, the researcher advises male players to train with the combined method because it improves the male hormone compared to other methods used in the study.
