Background and study aims
Tennis is an entertaining sport that includes a combination of technical, tactical and physical fitness components. This study aims to investigate the effect of core training on anaerobic performance and some physical performance values of tennis players studying at university and training on certain days of the week.
Who can participate?
Students aged 18-23 years old who are studying at Sivas Cumhuriyet University
What does the study involve?
Participants in the study were allocated into the experimental group (15 males) and a control group (15 males). Height, body weight, flamingo balance test, vertical jump test, balance and pro-agility test were applied to the subjects as pre-test and post-test. The experimental group practised core training 3 times a week along with tennis training 3 days a week. The control group participated only in tennis training. The study was conducted for 6 weeks.
What are the possible benefits and risks of participating?
Where is the study run from?

| Intervention | This is an experimental study. It aims to investigate how a 6-week core training program applied to tennis students studying at Sivas Republic University effects the performance of the athletes. 30 students between the ages of 18-23 who were studying at Sivas Cumhuriyet University, participated in the study as an experimental group (15 male ) and a control group (15 male). Height, body weight, flamingo balance test, vertical jump test, balance and pro-agility test were applied to the subjects as pre-test and post-test. The experimental group practised core training 3 times a week along with tennis training 3 days a week. The control group participated only in tennis training. The study was conducted for 6 weeks. Research Model The research was designed as a pretest and posttest. The information on what core training was included and how it would be performed was provided in the first interview. Two measurements were taken from the individuals participating in the study pretest and posttest. Data Collection Tools Crunch: Athletes wait readily lying in a supine position with knees bent and hands on the nape. Then they are asked to lift their bodies up and touch the knees with the elbows for 30 seconds. The repetitions that do not follow the rules are not accounted for. Crunches performed correctly for 30 seconds are recorded. Flamingo Balance Test: Athletes stand on the balancing beam and try to stay balanced for one minute. The foot balanced on is placed on the beam, and the other foot is held by hand and pulled to the hip. Timing is stopped when athletes lose balance or fall from the beam. Scoring is recorded as total balance achieved in one minute. Vertical Jump Test: Subjects are asked to stand with feet aligned with the pelvis and hands on both sides and achieve a 90-degree angle and squat, then jump quickly and as high as they can. They land on the designated spot. Those landing outside the spot repeat the test. Feet must be strained and knees must not be pulled to the chest when jumping high. The test was performed twice and the highest score was recorded. Standing Long Jump Test: Athletes are asked to leap forward from a designated spot with adjacent feet. The test was applied 3 times and the highest score was recorded. Pro-Agility Test: Cones are placed 4-57 meters on the right and left of the starting line. Athletes wait readily on the starting line. Timing starts when athletes are ready. The test ends when athletes reach the starting line by first touching the cone on the right, and then the cone on the left. The best score out of 3 test results was recorded. Training Schedule: The training was applied for 6 weeks and 3 days a week. The experimental group attended core training along with tennis practice. The control group only attended designated tennis practice. The training exercises included 10 separate exercises every week. A training plan including 2 sets and 8 sets of repetitions was performed. While a five-second rest time was given between the repetitions, complete rest was given between tests. |
| Intervention type | Behavioural |
| Primary outcome measure | Core strength measured using a standardized core strength test (e.g., plank hold duration, sit-up count, etc.) at a pretest (before the 6-week training period) and posttest (after the 6-week training period) |
| Secondary outcome measures | The following secondary outcome measures are assessed at a pretest and posttest: 1. The number of crunches performed correctly in 30 seconds measured using data collected by counting the number of correct crunches at a pretest and posttest 2. Balance duration measured using the Flamingo Balance Test (total balance time in one minute) 3. Vertical jump height measured using the Vertical Jump Test (highest score recorded) 4. Standing long jump distance measured using the Standing Long Jump Test (highest score recorded) 5. Pro-agility performance measured using the Pro-Agility Test (best score out of 3 test results) |
