But
during spring drills he was hampered by a
strained right
hamstring, giving Clarett, sophomore Maurice Hall and redshirt freshman JaJa Riley a chance to shine.
Despite some reports in the football media yesterday suggesting that the
hamstring strain, if that is what it was, picked up by the Arsenal and Chile international forward Alexis Sanchez
during the Premier League away game with Norwich City would mean three weeks on the sidelines, there is still no definite timescale.
Symptoms of a
hamstring strain include: sudden sharp pain at the back of the thigh
during exercise, possible snapping or popping feeling, pain with walking, tender to touch and sometimes bruising.
As a result, stretching, particularly of the groin, hip,
hamstrings, Achilles tendon, and quadriceps,
during warm - ups before practices and games and
during the cool - down after playing, is particularly vital in reducing the risk of
strains and sprains.
They work especially hard
during sprinting, and generally
hamstring strains occur when someone is running as fast as they can.
The Nordic
hamstring curl allows coaches to load the ECCENTRIC portion of the lift, which is key to increasing the tensile strength and resistance to
strain during explosive movements where the hips and quadriceps kick into full force mode.
The greater anterior pelvic tilt and peak hip flexion on the injured side may lead to a greater maximum length of this
hamstring muscle
during running, which may predispose them to greater risk of recurrent
hamstring strain injury.
It was originally suggested that
hamstring strain injury occurred most commonly
during the early stance phase, as this is where both knee flexion and hip extension moments are highest (Mann & Sprague, 1980).
The Nordic
hamstring curl is the primary exercise used for performing eccentric training of the
hamstring musculature
during long - term trials investigating
hamstring strain injury prevention (Gabbe et al. 2006b; Engebretsen et al. 2008; Arnason et al. 2010; Petersen et al. 2011; Van der Horst et al. 2015) although a range of others have also been developed that may also be suitable (Askling et al. 2013; Orishimo & McHugh, 2015).
Therefore, much of the anatomical research into the
hamstrings has focused on their role
during running and the potential for
strain injury.
Comparing
hamstring strain injury prevention and rehabilitation exercises, Orishimo & McHugh (2015) found that the supine sliding leg curl (Slider) produced greater gluteus maximus EMG amplitude
during the eccentric phase than the standing elastic - band resisted hip extension, the standing trunk flexion (Glider) or the standing split (Diver).
Indeed, Arumugam et al. (2015) reported that the increase in gluteus maximus EMG amplitude
during walking was present in individuals with and without a history of prior
hamstring strain injury.
