Brief summary: Despite the importance of physical activity for adolescent physical development, the specific impact of different types of exercise training on fine motor skills and testosterone concentration is unknown. A primary aim of this study was to analyze the benefits of cardiovascular and coordinative exercise training on fine motor skills in an adolescent population. A second aim of our study was to determine the testosterone concentration after physical stress of cardiovascular and coordinative exercise training and if testosterone was related to fine motor skills among adolescents following an exercise training intervention.

Detailed description: We assigned 135 adolescents (68 girls, 12-15 years of age) from Lithuania. Adolescents were assigned to one of three groups: control group (CON) (n = 46; 23 girls), coordinative exercise (CE) (n = 41; 22 girls), and cardiovascular exercise (CVE) group (n = 48; 23 girls). Participants performed all necessary tests according to the study protocol one week before the intervention. Adolescents were familiarized with the tests on a separate day before the first assessment. A second set of tests was performed one week after the 10-week exercise intervention.

The exercise intervention period was 10 weeks. Exercises were led by a Physical Education teacher. Experimental groups had common physical education classes twice per week for 45 minutes each, and additional exercise sessions were held three times per week for 45 minutes after school.

Eligibility criteria: Inclusion Criteria:

* absence of physical impairment (e.g. traumatic injury)
* absence of mental impairment (e.g. mental retardation)
* no consumption of psychotropic medications

Exclusion Criteria:

• restrictions to do exercises (based on Medical certificate issued by the Physician)
