Muscle strength, muscle explosiveness and muscle endurance are some of the key factors of success in carrying out everyday activities and they are especially important for sports activities. A tool that can help us in achieving better muscle strength, muscle explosiveness and muscle endurance is a kettlebell weight. What makes kettlebell training different from other types of training is primarily the simplicity of the equipment and the characteristic weight shape that enables the entire body activation during training. For this reason, the aim of this study was to determine if there are any significant differences in muscle strength, muscle explosiveness and muscle endurance at healthy recreational athletes who do strength training twice a week and also run a kettlebell dead stop swing protocol. This study was entered by 20 healthy recreational athletes divided into two groups, experimental and control, 18 of them successfully completed the default protocol. Study implementation consisted of the initial and final isokinetic testing of hip and knee flexors and extensors, as well as of the initial and final explosive strength tests (horizontal and vertical jump). The results between groups showed a statistically significant difference in the power of hip joint muscles and explosive strength tests, but no statistically significant differences were found in the power of knee joint muscles and the endurance of hip and knee joint muscles at p < 0,05 level. Therefore, it has been concluded that in this case the kettlebell dead stop swing protocol combined with strength training during six weeks leads to an increase in the power of the hip joint muscles and the explosive strength, but does not significantly affect the increase in the power of the knee joint muscles and the endurance of the hip and knee muscles.
