“…Despite the increased focus on hamstring strengthening exercises, there is currently only a little evidence available on the muscular forces and the contraction mode of the hamstrings during these exercises. Indeed, although the NHC has been shown to be effective at reducing hamstring injuries (when compliance is adequate) and at improving sprint performance and hamstring strength 19 and fascicle length, 10,20 the hamstring muscle forces and fascicle behavior during this exercise that may explain these adaptations remain largely unknown, with only one study so far investigating fascicle behavior during a portion of the exercise 21 . Similarly, the single‐leg RCH has also been suggested to be an effective hamstring strengthening exercise because it is believed to also result in high hamstring muscle forces and to mimic the quasi‐isometric hamstring action observed during (a part of) the late swing phase of running 1,22 .…”

Hamstring injuries are one of the most common injuries in sports that involve high-speed running such as football and have a high risk of recurrence. Hamstring injuries frequently involve the biceps femoris long head and are believed to occur during the late swing phase of highspeed running when the muscle-tendon unit reaches its peak length and develops a high force. 1 Modifiable risk factors for hamstring injuries include low levels of hamstring strength 2 (although the association is weak when considered in isolation 3,4 ), poor hamstring strength

“…Training programs that increase eccentric strength decrease the number of hamstring injuries and their severity throughout a soccer season (Askling, Karlsson & Thorstensson, 2003;Petersen et al, 2011). NHE is currently the most widely used exercise within these programs, as it reduces the risk of injury by up to 51% (Van Dyk, Behan & Whiteley, 2019) and produces mild to moderate improvements in jumping and sprinting performance (Bautista et al, 2021). In agreement with this author, according to Ishøi et al (2018) the performance of NHE in amateur players would produce small to medium improvements in sprint performance.…”

Background The use of a functional electromechanical dynamometer (FEMD) has been proposed as a valid and effective tool to evaluate specific movement patterns. The aim of this study was to determine the reliability of FEMD on swing eccentric hamstring exercise (SEHE) measures in soccer players. Methods Nineteen federated male soccer players (20.74 ± 4.04 years) performed the SEHE at three different isokinetic velocities (20–40–60 cm/s). These evaluations were conducted in four sessions, two for familiarization and two for registration. The average and maximum load (N) of the three isokinetic velocities was calculated from the values obtained from the FEMD (Dynasystem®, Bangalore). Results The main results of this research showed that the reliability was high for the average load in the condition of 40 cm/s, presenting the highest ICC value (0.94). For maximum load, reliability was high in the condition of 20 cm/s. The manifestation of the most reliable load was the maximum load (ICC = 0.91–0.87). Conclusions FEMD (Dynasystem®, Bangalore) is a reliable device to evaluate the eccentric strength of the hamstring muscles in soccer players.

“…Hence, further studies are needed to confirm the optimal ankle position for prediction of the risk of HSI by peak eccentric force during the NHE. On the other hand, it has been reported that NHE training improves peak eccentric force during the NHE and several variables related to HSI, such as sprint performance and hamstring fascicle length (Bourne et al, 2017;Bautista et al, 2021). The effect of ankle position on the efficacy of NHE training is an interesting matter from the viewpoint of HSI prevention.…”

Peak eccentric force during the Nordic hamstring exercise (NHE) is recognized as a predictive factor for hamstring strain injury (HSI). During the NHE, the knee flexor muscles are eccentrically contracting to resist the knee joint extension. Therefore, it is thought that the action of the gastrocnemius muscle, and thus the ankle position, influences peak eccentric force during the NHE. However, the effect of ankle position on peak eccentric force during the NHE remains unclear. Therefore, we investigated the effect of ankle position on peak eccentric force during the NHE in a cohort of 50 healthy young male rugby players (mean age, 18.7 ± 1.2 years; mean body mass, 81.7 ± 15.2 kg; height, 1.72 ± 0.06 m) with no history of HSI. Each participant performed NHE strength testing with the ankle dorsiflexed or plantarflexed position and was instructed to fall forward as far as possible within 3 s. Peak eccentric force, reported relative to body mass (N/kg), of both legs was recorded, and the mean values of both legs were compared in both ankle positions. The mean peak eccentric force was significantly greater with the ankle plantarflexed position than the dorsiflexed position (3.8 ± 1.1 vs. 3.5 ± 1.1 N/kg, respectively, p = 0.049). These results indicate that ankle position should be carefully considered when measuring peak eccentric force during the NHE and performing NHE training.
