Brief Summary

This study was conducted to investigate the effects of a calisthenic exercise program on static/dynamic strength and muscular endurance in young male kickboxers. Methods: A total of 20 kickboxers between the ages of 20-26, healthy, and actively involved in this branch for at least 4 years participated in the study. The volunteers participating in the study were randomly divided into two groups as the study and control groups. The study group applied calisthenic strength exercises in addition to routine kickboxing technical training for 8 weeks and 3 days a week, while the control group continued only their weekly routine kickboxing training without applying any strength training. Static strength performance (grip-leg-back), dynamic strength performance (1RM bench press and 1RM barbel squat), 30-second push-ups and 30-second sit-ups tests were applied to the athletes participating in the study before and after the 8-week training. SPSS 25.0 and JASP statistical package programs were used in the evaluation of the data obtained in the study and the significance level was accepted as 0.05.

Outcome Measures

Primary Outcomes (5)

  • Determination of height and body weight

    All participants were determined with an Oncomed brand SC-105 model 0.1 kg precision measuring device and the body mass index (BMI) value was calculated.

    from the beginning of the work until the end of 8 weeks

  • 30-second push-up test

    After the subjects took a position on the floor mat, they were asked to lower their bodies until their elbows reached 90 degrees, with their arms open at shoulder width, elbows straight and tense, without touching the ground and without creating a concave waist, and then return to the starting position after approaching the ground. The number of regular push-ups performed for 30 seconds was recorded.

    from the beginning of the work until the end of 8 weeks

  • 30-second sit-up test

    After the subjects lay on their backs on a mat laid on the floor, their arms were joined on their chests and their knees were at a 45° angle. The subjects were asked to lift their bodies 90° off the ground and touch the ground again in the starting position. The number of regular sit-ups performed for 30 seconds was recorded.

    from the beginning of the work until the end of 8 weeks

  • Static strength measurement test

    A dynamometer was used to determine the grip, back and leg strength of the subjects.

    from the beginning of the work until the end of 8 weeks

  • Dynamic strength measurement test

    The maximal weight that all participants in the study could lift at one time was determined with the 1 repetition maximal (1RM) method of the bench press movement, one of the basic exercises for the upper extremity, and the barbell squat movement, which is considered a basic exercise for the lower extremity.

    from the beginning of the work until the end of 8 weeks
