Isolated injury to the long head of biceps femoris is the most common type of acute hamstring strain injury (HSI). However, the precise hamstring injury mechanism (i.e., sprint-type) is still not well understood, and research is inconclusive as to which phase in the running cycle HSI risk is the greatest. Since detailed information relating to hamstring muscle function during sprint running cannot be obtained in vivo in humans, the findings of studies investigating HSI mechanisms are based on modeling that requires assumptions to be made based on extrapolations from anatomical and biomechanical investigations. As it is extremely difficult to account for all aspects of muscle-tendon tissues that influence function during high-intensity running actions, much of this complexity is not included in these models. Furthermore, the majority of analyses do not consider the influence of prior activity or muscular fatigue on kinematics, kinetics and muscle activation during sprinting. Yet, it has been shown that fatigue can lead to alterations in neuromuscular coordination patterns that could potentially increase injury risk. The present critical review will evaluate the current evidence on hamstring injury mechanism(s) during high-intensity running and discuss the interactions between fatigue and hamstring muscle activation and function.

This study aimed to investigate the effects of a ball-oriented soccer match-play simulation on the hamstrings eccentric torque production. Seven male recreational athletes volunteered for this study. Participants completed 90-minutes of the ball-oriented soccer simulation interceded by a 15-minute half time interval with five successful trials of hamstrings eccentric contractions on an isokinetic dynamometer at selected time points throughout the simulation. A 2 (limb: dominant; non-dominant) × 4 (time: 0 min; 45 min; 60 min; 105 min) “split-plots” analysis of variance (SPANOVA) revealed significant reductions in hamstrings eccentric peak torques over time, while no significant change was apparent in hamstrings eccentric angles of peak torque. There was also no interaction effect of limb dominance over time for both peak torque and angles of peak torque parameters. The observed changes suggest that exertions from a ball-oriented soccer match-play simulation may have detrimental effects on the hamstrings eccentric strength parameters thus may increase risk of ACL injury. High variabilities in angles of peak torques were also observed in this study. Future exploration is warranted in order to address the extent of variabilities that may be present in larger sample sizes thus providing a better understanding of the influence of these variabilities on the muscular strength parameters of ACL injury risk. The findings suggest firstly, that fatigue from soccer-specific exertions during match-play may increase an athlete’s susceptibility to ACL injury, and secondly, that with accumulating fatigue, the nondominant limb may be equally at risk of injury as the dominant limb, contradicting previous findings from epidemiological studies.

AbstractHamstring injuries and reinjuries are one of the most important sport lesions in several sport activities including soccer, Australian football, track and field, rugby, and in general in all sport activities requiring sprinting and acceleration. However, it is important to distinguish between the lesions of the biceps femoris and semitendinosus and semimembranosus. Indeed, three muscles representing the hamstring complex have a very different injury etiology and consequently require different prevention strategies. This fact may explain, at least in part, the high incidence of reinjuries. In soccer, hamstring injuries cause an important rate of time loss (i.e., in average 15–21 matches missed per club per season). The hamstring injury risk factors may be subdivided in three categories: “primary injury risk factors” (i.e., the risk factors mainly causing a first lesion), “recurrent injury risk factors” (i.e., the risk that can cause a reinjury), and bivalent injury risk factors” (i.e., the risk factors that can cause both primary injuries and reinjuries). The high incidence of hamstring lesions caused consequently an important increase in hamstring injury research. However, although the prevention has increased paradoxically, epidemiological data do not show a loss in injuries and/or reinjuries but, on the contrary, they show an increase in hamstring injuries. This apparent paradox highlights the importance both of the improvement in the prevention programs quality and the criteria for return to play after hamstring injury.
