Objective: The aim of our study is to investigate the effect of percussion massage applied to the quadriceps muscle with a Hypervolt device on range of motion (ROM), jumping, agility and anaerobic performance. Material and Methods: Total of 24 (41.7% female, 58.3% male) healthy individuals with mean age of 22.04±1.19 years participated in the study. A cross-randomization method with a 72-hour washout period was used throughout the study. Percussion massage (Hyperice, California, USA) was applied to the dominant quadriceps muscle of the participants lying in the supine position for 8 minutes at a frequency of 30 Hz using the flat head of the Hypervolt device. ROM, vertical jump, T Drill Test and Wingate anaerobic performance tests (WAnT) were evaluated. Results: Hip flexion ROM of the participants increased significantly after percussion massage with Hypervolt (p=0.02). There was no significant difference in vertical jump and T Drill Test results and ROM measurements other than hip flexion after percussion massage with Hypervolt (p˃0.05). WAnT results were found to be decreased (p<0.05). Conclusion: While percussion massage device has positive effects on joint range of motion, they have no effect on jumping and agility performance. However, there was a decrease in anaerobic power output. Percussion devices such as Hypervolt which are utilized for warming up may reduce anaerobic performance.

Objective: The aim of this study is to determine the effect of neuromuscular fatigue created in the core region on the biomechanics of landing. Materials and Methods: Healthy individuals aged between 18-25 years and without any musculoskeletal injury that prevented them from performing the landing test were included in the study. In the study, cross-over randomization was applied. After the descriptive characteristics of the individuals (lower extremity length, Q angle, range of motion etc.) participating in the study were recorded, core region endurance was evaluated with curl-up test, static back endurance test (Biering Sorenson test) and horizontal side bridge test. Subjective fatigue protocol was created with the prone bridge test. The effect of the fatigue caused by the prone bridge test performed during applied time on the biomechanics landing was examined with the 'Landing Error Scoring System'. Results: The study included 21 women (77.8%) and six men (22.2%) whose age was 21.7±0.2 (21-25) years, height 168.7±1.6 (156-190) cm, body weight 59.3±1.6 (46-80) kg and body mass index 20.8±0.5 (17.5-28.8) kg/m2. It was determined that fatigue caused by the prone bridge test performed during applied time did not make a difference in the landing error score of the participants (p=0.545). It was determined that the results of the curl-up test and right horizontal side bridge test, in which endurance of the core region was determined, revealed a negative linear relationship with the landing error scores obtained after the fatigue protocol. Conclusion: Increasing core region endurance of healthy individuals is associated with the response of lower extremity biomechanics to fatigue. Therefore, it is recommended that endurance exercises for the core region should be made a part of training programs.

Biyomekanik ve hareket analizi konuları, spor hekimleri tarafından günden güne önemi artan alanlardandır. Hareket analizi sistemleri, farklı hareket paternleri sonucunda biyolojik dokunun etkilenimini incelemekte ve bu etkilenimi verilere dökmektedir. Bu veriler ışığında klinisyen, yaralanma öncesinde ve sonrasında yaralanmanın önlenmesi, tedavisi veya rehabilitasyonu konularında daha efektif yöntemlere başvurabilmektedir. Profesyonel sporcular ve rekreasyonel düzeyde sporla ilgilenen bireyler, sıklıkla fırlatma ve koşma eylemlerini içeren aktivitelere katılmaktadır. Fırlatma eylemi toplamda 4 fazdan oluşmakta ve bu eylem sırasındaki teknik hataların düzeltilmesi özellikle üst ekstremite yaralanmalarının önlenmesinde ve tedavisinde çok büyük önem arz etmektedir. Koşma eylemi ise 5 fazdan oluşmakta ve biyomekanik olarak incelenmesi alt ekstremite yaralanmalarının önlenmesinde ve tedavisinde önemlidir. Bu derlemenin amacı, spor hekimliği pratiğinde sık kullanılan hareket analizi sistemlerinin, üst ekstremite ve alt ekstremite biyomekaniklerinin güncel bilgiler ışığında okuyucuya sunulmasıdır.

Objective: Aim of study is to determine the football injuries that occurred in football matches played in 1937-1938 National Cluster (in Turkish: Milli Küme) Football Season by using newspaper clippings of period and to analyze the content with the current sports medicine approach. Material and Methods: In study, in order to examine the sports injuries in 1937-1938 football season, newspapers of period to be used in content analysis were determined. These newspapers were reviewed from digital archive at www.gastearsivi.com. In study, which did not require ethics committee approval in terms of its scope, football injuries mentioned in newspaper clippings were categorized according to football injury classification. Results: A total of 37 sports injuries were detected in 48 games played throughout the season. Among these 37 injuries, 38% (n=14) contusion, 24% (n=9) strain or sprain, 13% (n=5) concussion, 11% (n=3) laceration, 8% (n) according to injury type. =3) fatigue, 3% (n=1) blunt abdominal trauma, and 3% (n=1) disease; When we examined according to injury site, 59% (n=22) lower extremity, 24% (n=9) head, 11% (n=4) whole body, 3% (n=1) upper extremity and 3% (n=1) abdominal region injuries were detected. 64% of these injuries were caused by contact (n=24), 36% (n=13) by non-contact injury mechanism. Conclusion: Football injuries were common in 1937-38 National Cluster season. Although the diagnosis and/or treatment approaches are different from today's due to medical and sports conditions of period, it is valuable to be able to comment on period in line with information obtained from the newspaper clippings. In line with this result, we believe that our study will shed light on similar studies to be conducted in the future methodologically.
