Google Trends "pulled quad" vs. "pulled hamstring" (https://www.google.com/trends/explore#q=%22pulled%20quad%22%2C%20%22pulled%20ham string%22&cmpt=q&tz=Etc%2FGMT%2B5)

Why are hamstrings so susceptible to being pulled? Also, I love the seasonal effect visible in the graph below.

Article suggests bicep femoris is shorter than the other two hamstring muscles, thus requiring a longer stretch. (http://www.heraldsun.com.au/news/victoria/researchers-discover-why-hamstring-muscle-is-so-prone-to-injury/news-story/c4027887be86d5619e658a85d6d417eb)

的f you think about the hamstrings being constrained by the hip and knee joint, obviously when you move your knee, all three hamstring muscles have to move to their maximum length at the same time, Dr Dolman said.

典hey have to stretch together. One can稚 stretch while the other is shortening.

的t has to complete a larger stretch in the same time frame as the other two hamstring muscles, so it痴 more prone to fatigue.


The Academic Study (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4241430/) cited in the above article has this advice.

Until further research is completed, only theoretical applications on the value of the findings of this study can be applied. One such application would be that, as the biceps femoris is more susceptible to injury because it exerts more force to complete a longer stretch in the same amount of time than either the semimembranosus or semitendinosus muscles, it seems feasible to suggest that, if these other muscles of the hamstring group could be trained to stretch further during hamstring action then the biceps would require less force to sustain eccentric muscle action. This application might have relevance when the total postural/muscle factors including gluteal muscles and lower lumbar spine can be appropriately assessed and acted upon. Finally, enhancing fatigue resistance by training may also be a fruitful area in preventing hamstring injuries. This has been the basis of some in the field hamstring injury prevention programs

Bad design. Like the knee as a whole (and the shoulder), this stuff just wouldn't pass QA today given the current specs. Change requests must be filed...
