Live hamstring muscle injury during curve sprinting: a case report

Hamstring (HM) muscles have a high rate of injury especially on the track-field where they can represent as much as 50% of all injuries. It is generally accepted that HS injuries have a multifactorial origin, highlighting the need to individualize the evaluation process in a multidimensional manner. Although many studies have been conducted on the kinematic characteristics of sprinting (e.g., HM activation), only few studies have observed the electromyographic activity captured during a live HM injury, nor reported the relationship with the athlete’s cognitive, behavioural and psychological context such as thoughts, intentions and emotions prior to the onset of injury.
We here describe the case of a male sprinter that sustained a biceps femoris long head (BFlh) muscle injury during a curve sprinting protocol to underline the potential impact of its very high BFlh electromyographic activity captured during the injury. Additionally, we reported the athlete’s psychological and behavioural state as potential crucial elements that may have contributed to the onset of the injury.
