INTRODUCTION


Sport is a biological, pedagogical social phenomenon that improves the physiological and psychological health of the individual, regulates social behaviors, and brings it to a certain mental and motoric level. In other words, sport is defined as a phenomenon that ensures the intellectual, spiritual and physical development of the individual and the coordination and socialization among these elements (Lloret et al., 2021).


Today, tennis sport; It is an olympic sport that is embraced by the world and that at the same time arouses excitement and admiration to do and watch. In this sport, it is known as a sport that includes aerobic and anaerobic loads and sudden changes of direction, as well as requiring a high level of basic motor features such as strength, speed, endurance, flexibility and coordination, and athletic performance ( Przybylski et al., 2021).


Warm-up is generally referred to as the practice of preparing the athlete for performance and increasing the performance of the athlete (Silva et al., 2022). The warm-up, which is shaped according to the type of exercise to be performed and the energy system used, is used to increase muscle temperature and provide adaptation to exercise (Jordan et al., 2021). It is seen that warming up, which is defined as getting good efficiency from the athlete, protecting from injuries and preparing the athlete for the loads physiologically and psychologically, increases performance and is used to reduce the risk of muscle damage with neurological, biomechanical and psychological mechanisms (Reeves et al., 2021).


Warming up by Akgün (1994); It is a work that aims to prepare and adapt the athletes to certain tasks envisaged in training and matches, both mentally and physically, in the most appropriate way”, it is also stated that the better and correctly the warm-up is done, the risk of injury will decrease and the performance will increase in every aspect. expressed as a sign. In this context, it is thought that the level of warm-up knowledge and warm-up habits are important for the performance of athletes and athletes. In line with this information, the aim of the research is; In the Eastern Anatolia Region (Elazığ, Van, Bingöl, Malatya) tennis players' knowledge levels of warming habits and determination of their sportive performances were investigated.


METHODS


The research group consists of 167 (66 women, 101 men) volunteer athletes who took part in licensed national/international tournaments in the Eastern Anatolia Region (Elazig, Van, Bingol, Malatya) tennis branch. While the scale was preferred as the data collection tool in data collection, the scanning model was used to determine the "Warm-up Habits" of the athletes. The scale used in the study consists of two parts. In the first part of the scale, "Personal Information Form" containing the demographic information of the athletes, and in the second part, the "Athlete Warming Habit Information Form", which includes the knowledge levels of tennis players' warming habits and used by Arslan et al., (2011).

(p>0.05).


DISCUSSION


Araştırmada Doğu Anadolu Bölgesinde (Elazığ, Van, Bingöl, Malatya) tenis branşında lisanslı ulusal/uluslararası turnuvalarda yer almış 167 (66 kadın 101 erkek) gönüllü sporcunun ısınma bilgi düzeylerini ve sportif performanslarını belirlenmesi amacıyla yapılmıştır.


In line with the findings obtained from the research, if it is necessary to evaluate the tennis players' warming habit information form percentage frequency values according to the study group; While 91% of them gave a positive opinion on the item "warm-up reduces the risk of injury for athletes", it was the most preferred item; It can be said that the athletes are very sensitive on this issue and this item explains the reason why they give the most importance to the subject of warming up. On the positive side, if it is necessary to rank the items that they pay more attention to, according to their percentage values; 85% for the article "Warm-up increases the athlete's angle of motion by creating positive effects in the joint areas"; It was determined that 76% of them gave a positive opinion on the item "Warming has an important role in better contraction and relaxation of the muscle". It can be interpreted that the items in which the athletes gave positive opinions were actually informed about these issues. In addition to these; The fact that 42.5% of them gave an opinion on the item "Warming up does not have an effect on the oxygen intake capacity of the athletes" can be expressed as an indication that the athletes are not aware of this issue. Özbar et al. (2017) conducted a study on the evaluation of warming habits and knowledge level of female football players at the 1st and 2nd league level. 94.3% of the 1st League athletes participating in the research think that the risk of injury after warming up is less, and 82.8% think that sweating is a symptom of warming up. The results obtained from the research show parallelism with the findings of our study.


Aslan et al., (2011) in their study on the evaluation of warm-up habits and knowledge levels in amateur athletes, concluded that warming up has a positive effect on athlete performance and reduces the risk of injury among amateur athletes, another finding that supports the research.


In line with the findings obtained from the research, as a result of the evaluation of the item averages of the tennis players' warming habit form; The statement “Warming reduces the risk of injury in athletes” has an average of 4.79±0.76 items, and the statement “Warming has an important role in better contraction and relaxation of the muscle” has an average of 4.67±0.68 items; it was determined that the total mean score of the participants from the knowledge level of warming habits was 73.80±10.52. It can be interpreted that the average score determined as a result of the research is that the participants' knowledge of warming is good and that they participate by understanding the items and identifying them with themselves. Letafatkar et al. (2021) conducted a study on a comprehensive warm-up program to prevent injuries in young female football players. The research examined the effect of warming up in terms of static and dynamic movements in a total of 1892 female football players, whose average age was between 13-17, 1055 in the experimental group and 837 in the control group. As a result of the research, it was determined that in addition to the level of knowledge about the warming habit in the experimental and control groups, applying this habit is a necessary behavior for an athlete.


In line with the findings obtained from the research, it was determined that there was no statistically significant difference between the demographic information of tennis players, gender, warming knowledge levels and total score averages of the habit of doing warm-up exercise (p>0.05). Studies supporting the study are also included in the literature. In the study conducted by Sánchez-Díaz et al. (2021), on the examination of warming habits and warming knowledge levels of university athletes, a comparison was made according to gender. In the research, “Warm-up increases the athlete's range of motion by creating positive effects in the joint areas”; It was stated that women did not agree with the statement "Warm-up time should be half of the training time" with an average of 3.42 points, while men "disagree" with an average of 3.12 points. In other articles; It was determined that the knowledge of warming habits did not differ between genders. Choi et al. (2018) in the study on the examination of the knowledge and habit levels of university students studying in sports departments about warming up and cooling down exercises in sports activities; While it is concluded that the general knowledge and habit levels of the participants about warming up and cooling down in sports do not differ significantly according to their gender and sports age, it supports the results of the research.


In line with the findings obtained from the research, as a result of the analysis made in order to determine the reasons for the athletes to prefer the tennis branch according to the demographic information; of the athletes in the research group; While it was determined that there was a statistically significant difference according to age, education status, year of sport, sportive degree, habit of doing cool-down exercise, duration of warm-up exercise and cool-down exercise (p<0.05), there was no statistically significant difference according to injury status. (p>0.05). In this context, it can be said that warming up and cooling down exercises in sports are very important in both sports performance and reducing the risk of injury, while the increase in age and experience of sports years contributes to the improvement of the athlete's degree positively. There are studies in the literature that support the research results.Kirişçi (2011) found in his study that the majority of the athletes (89.2%) were doing cool-down exercises, while only a few (10.8%) did, and nearly half of the athletes (45.6%) spent enough time on general warm-up for exercise. . In his study with boxers, Hekim (2015) evaluated the findings regarding warm-up and cool-down exercises, and as a result, he determined that warming up and cooling down is important in sports. Woods et al., (2007) stated that 40.7% of the athletes participating in the study had never been injured, and more than 30% of the injuries were skeletal muscle injuries. From this point of view, the fact that insufficient warm-up and over-training cause injuries emphasizes the importance of warm-up knowledge level. Contrary to our research findings, there are studies that found a significant relationship between warm-up exercises and injury frequency (Fernandes et al., 2015; Grooms et al., 2013; Turki et al., 2019).


As a result; Tokgöz et al. (2015) in the study; It was stated that the university sports department students who are interested in team and individual sports have a high level of knowledge about the importance of warming up and cooling down in sports, whereas the level of cooling off exercises after training and competition is low.


CONCLUSION


Considering that warming up is an important element for sports activities, it is thought to be effective on all sports activities and performance.
