Objectives: Most of the people who visit the gyms start to lift weights without basic workout training. The aim of our study was to investigate how an educational course on training theory and training techniques could prevent injuries and pain among those who train with weights in the gym.

Methods: The type of research is quantitative, real experimental research. The place of research is the Cutler Gym & Fitness Centre in Pécs, Hungary. Date of the research: 01.05.2018 - 01.06.2019. Sample size was 100 persons (N=100). 50 people belong to the study group (SG) and 50 people belong to the control group (CG.). We examined non-professional hobby athletes, who had been performing weight training at least twice a week for at least one year during the injury-free period. Data was collected using a self-designed questionnaire and objective measurements.

Results: By the end of the educational program, the study group had a higher proportion of those who paid attention to the correct implementation of the exercises before the program (b.p.) – 22%, after the program (a.p) – 79,55%) (p=0.001), of those with a significantly reduced total annual injury (b.p. - 14.05 injuries / person / year, a.p. – 6.59 injuries / person / year) (p=0.001). The warm-up and stretch time of the study group increased significantly (b.p. 2.3 min., a.p. 13,25 min) (p<0.001) and (b.p. 1.92 min., a.p. 7.39 min) (p<0.002). There was a significantly greater reduction in weight training time in the SG than in the CG (p=0.001). Those who were involved in the educational program their percentage of body fat decreased significantly (CG decreasing 0.14%, SG decreasing 1.97%) (p=0.04).

Conclusions: Based on our results it can be stated that a basic educational course on training theory and training techniques reduces the number of injuries caused by training with weights.
