As a dedicated Fitness Professional, and long-time, enthusiastic sports and training student/practitioner, it is an on-going mystery as to why so many Hamstring injuries still remain as such a prevailing problem. As has been indicated previously in these blogs, strictly applied progressive strength, range and motion loads to the muscles and structures along the posterior chain (of which Hamstrings are an integral component) will produce inherent strength adaptations in this vitally important muscular/structural sequence.
It is of increasing concern, that the greatest emphasis in this area of gross sports related weakness seems to be more about injury treatment and rehabilitation than it is about prevention. (If this is not the case, current statistics and perceptions bely any such assertion). Modern training methods recognise the principal areas of note, but do not seem to apply systemic practices to alleviate/protect against these all too common interruptions to athletes in the performance of their chosen sports.
While it is conceded that there is no absolute guarantee against even one kind of soft tissue injury, absolute prevention is not the only focal area to be considered, as even if these injuries do occur, if relevant training adaptations have been of any benefit at all, then the period required to return to athletic performance should be diminished. That is to say, if a hamstring injury in earlier sporting eras kept an athlete out for a period of three to four weeks, then in this more knowledgeable time, training/medical understanding should be limiting this to one to two weeks. However, this is most definitely not the case, as clearly there has been no progress in this area. It seems that there are multiple Hamstring injuries to athletes on a weekly basis, not only in fierce competitive situations, but also on the training track. Once again, a clear indication that not only is not enough being done on the posterior chain, but it is not consistent enough, and does not carry with it correctly applied loads to the relevant inclusions along this vulnerable region. Furthermore, this responsibility lies within the scope of the strength & conditioning experts, as once the injury has occurred, medical/rehab personnel are powerless in limiting the extent of damage, and the recovery timeframe.
Notwithstanding all that has been said earlier in this piece, the most common error in preparing the posterior chain, is all too often a narrowly constructed and single minded specificity approach towards the Hamstrings, and even the posterior chain in isolation to other key physiological/anatomical factors. Due to the enormous reciprocal role of Hamstrings and the Lumbar spine, and by extension the co-operative intrinsic relationship of deep spinal inclusions and Transverse abdominis, essential Hamstring strength & conditioning is not complete without appropriate inclusion of primary, secondary and peripheral core adaptations, and how each individual athlete is able to respond and adapt to recently conceived multi-directional, tri-planar proprioceptive strength and fitness innovations.
