TLDR
Results indicate that soccer players with an increased tightness of the hamstring or quadriceps muscles have a statistically higher risk for a subsequent musculoskeletal lesion.Abstract:
Background: Muscular tightness is frequently postulated as an intrinsic risk factor for the development of a muscle injury. However, very little prospective data exist to prove this.Hypothesis: Increased muscle tightness identifies a soccer player at risk for a subsequent musculoskeletal lesion.Study Design: Prospective cohort study.Methods: We examined 146 male professional soccer players before the 1999—2000 Belgian soccer competition. None of the players had a history of muscle injury in the lower extremities in the previous 2 years. The flexibility of the hamstring, quadriceps, adductor, and calf muscles of these players was measured goniometrically before the start of the season. All of the examined players were monitored throughout the season to register subsequent injuries.Results: Players with a hamstring (N = 31) or quadriceps (N = 13) muscle injury were found to have significantly lower flexibility in these muscles before their injury compared with the uninjured group. No significant differences...read more

Comparison Between Contract–Relax Stretching and Antagonist Contract–Relax Stretching on Gastrocnemius Medialis Passive Properties
Taizan Fukaya,Andreas Konrad,Shigeru Sato,Ryosuke Kiyono,Kaoru Yahata,Koki Yasaka,Remi Onuma,Riku Yoshida,Masatoshi Nakamura +8 more
TL;DR: The results of this study suggest that contract-relax stretching instead of antagonist contract- Relax stretching should be conducted to decrease muscle stiffness, however, either contract-Relax or antagonist contract tolling stretching can increase ROM.

TL;DR: Application of NDS& SMI to persons with short hamstring syndrome resulted in increases in flexibility of the hamstring, however the NDS technique was more effective.

Are Lower Extremity Injuries Related to Spinal form Abnormalities in Professional Football Players? A Prospective Cohort Study
Sara Lotfian,Navid Moghadam,Navid Moghadam,Bahar Hassnamirzaie,Bahar Hassnamirzaie,Salman Khalifeh Soltani,Salman Khalifeh Soltani +6 more
TL;DR: In this paper, the effects of various spinal form abnormalities on the rate of lower extremity injuries in male professional football players were evaluated and found that increasing thoracic kyphosis Cobb's angle was associated with a reduction in the likelihood of exhibiting quadriceps injury, odds ratio (CI 95%): 0.806 (0.671 - 0.968).

Incidence, Severity, Aetiology and Prevention of Sports Injuries A Review of Concepts
TL;DR: The extent of the sports injury problem is often described by injury incidence and by indicators of the severity of sports injuries, and the importance of the determinants of sports behaviour, as well as the interaction between the various aetiological factors, is discussed.

TL;DR: It is suggested that those with knee instability and those allowed to resume play with poorly rehabilitated or clinically unhealed injuries are more apt to sustain further injury.
