The purpose of this study was to examine the effect of 10 weeks of core training applied together with regular general weight lifting training on selected elements of anthropometric measures (body weight, waist, chest, hip, biceps, thigh, and calf circumference measurements), maximal strength (maximal snatch, maximal clean and jerk, maximal bench press, and maximal squat), and core strength (plank, trunk flexion, trunk extension, lateral flexion). The sample of weight lifters was sampled conveniently and was assigned into two groups: experiemental (n= 10, x̅age: 22.1± 1.1 years, x̅height: 1.74±.04 cm, x̅weight: 74.0±9.3 kg) and control (n= 10, x̅age: 22.7±1.1 years, x̅height: 1.77±05 cm, x̅weight: 73.9±7.6 kg). In this study, which was carried out using a pre-test-post-test quasi-experimental design, the participants were subjected to the basic weightlifting training 3 days a week for 10 weeks. The experimental group, on the other hand, was subjected to the core training program in addition to weightlifting training. Anthropometric measurements, maximal strength, and core strength measurements of the participants were taken twice, before and after the study. Within the scope of data analysis, Mann Whitney-U test was applied to compare the measurements of the experimental and control groups. Research findings revealed that core training applied in addition to weightlifting training produced a statistically significant decrease in waist circumference and an increase in biceps and calf circumference of the experimental group when compared to the control group. In addition, a significant increase in the clean and jerk strength was revealed in the experimental group's maximal strength measurements compared to the control group. When core strength measurements were examined, it was determined that the endurance of plank, trunk flexion, trunk extension, and lateral flexion were increased in the experimental group. As a result, it can be argued that weightlifting training applied together with core training may have a positive impact on maximal strength and core strength development.
