EG additionally participated in AGPAP (4:00 pm-5:00 pm) twice a week, every Wednesday and Friday, for a total of 60 minutes, for 12 weeks. AGPAP started the week after the pre-tests for EG. The intervention program consisted of 24 traditional street games, including running, hopping, galloping, leaping, jumping, sliding, striking, catching, ball catching, overhand throwing, balance, one-hand throwing, flexibility, coordination, shooting at the target, and hand-arm-leg strength and both outdoor and indoor facilities were utilized based on whether conditions. Each practice phase is 60 minutes long and includes three stages: instruction and warm-up (10 min.), AGPAP practice (45 min.), and cooling-down (5 min.). Two researchers who hold graduate degrees in physical education and sport led AGPAP and recorded children's participation. At the end of the intervention, the same testing procedures and testing materials were used for post-test measurements.

Measurements were applied to the CG

EG participated in AGPAP (4:00 pm-5:00 pm) twice a week, every Wednesday and Friday, for a total of 60 minutes, for 12 weeks. EG and CG did not participate in any additional physical activity programs after-school.

Body weights were measured using a digital scale (SECA, Hamburg) with an accuracy of 0.1 kg while subjects were wearing as light clothing as possible and barefoot. Heights were measured using a portable stadiometer (SECA, Hamburg) with an accuracy of 0.1 cm while subjects were barefoot, with their feet together and their heads on a horizontal plane 47. The weight(kg)/height2(m) formula was used to calculate BMI.

The hand grip strength test measures the explosive power of the upper body using an adjustable and calibrated hand dynamometer (Takei, Tokyo, Japan). Participants were asked to hold them in their right and left hands and squeeze it slowly and continuously until they reached the max. for at least 2 s. The best of 2 repetitions was recorded as the test score in kg.
