Aim: The purpose of this study is to examine the effects of 14-week training and tennis programme on physical and physiological profiles of boys aged 8 to 12 years. Method: The experimental group consisted of 14 healthy boys. The average age, body mass index (BMI), height and weight are 9,9±1,2 years, 17,9±3,5 kg/m2, 138,7±8,1cm and 34,4±10,3 kg respectively. Exercise sessions were carried out for 2 hours per week (Saturday and Sunday) over a 14-week period. Permission to conduct the study was obtained from parents, the medical committee and the Kafkas University Sarıkamış School of Physical Education and Sports. Some physical and physiological tests were measured. Hand grip strength, 20 m speed, balance, coordination, flexibility, anaerobic power, aerobic power, 30 s push-up, 30 s sit up, horizontal jump and pull-up tests were applied to subjects. The measurements were taken in resting condition before and after the 14-week exercise programme. Within the scope of the training programmes, there were 20 minutes of warm-up and gymnastics; 20 minutes of aerobic step to music to improve coordination and rhythmic skills; 20 minutes of educational games, including various types of sports (basketball, football, volleyball, handball); and finally, 60 minutes of basic tennis training. Each week, these activities were conducted in different ways to prevent them from becoming routine.Evaluation of the obtained data, SPSS for Windows 11.0 software with paired-samples t test was used for intra-group statistics. All measured parameters performed at the level of 0.01 and 0.05. Findings: As a results of the analysis, there were significant differences between pre-post tests of all measured parameters at the end of the study. Result: Consequently, 14 weeks regular training and mini tennis acivities has positive effect on physical and physiological developments of boys aged 8 to 12 years.
