Despite the apparent simplicity of running, there are many factors that affect performance, dealing with running injuries and finding the optimal training recipe. Running Science dismantles this apparent simplicity and outlines how much the individual's circumstances (genetics, preferences, injury history) make a difference when in comes to training plans and injury response, for instance, and repeatedly outlines that, although there is an increasing body of research on the topic, there are still many unanswered questions and areas where anecdotal evidence is available, rather than soundly tested scientific proof. No surprise here from my point of view, if we think about how inherently individualistic a sport running is.
The book overall synthesizes major themes of interest for runners and makes constant reference to studies to back up its assertions. I came across it while looking for texts that cover the psychological factors that influence running performance, and while from personal experience I know that finding relevant studies on runners isn't easy, I hoped for a greater number of studies cited or a few separate pages explaining the selection of studies referenced.
Running Science is definitely not an encyclopedia type of book, but it does address quite a few key matters (for instance, I found the chapter about running equipment particularly useful) and comprehensively explains how running works, from the physiological and anatomical point of view, as well as how things such as nutrients, music, equipment may influence your performance. There's also a healthy dose of myth busting. For instance, although the make-up (genetic or otherwise) of each individual can affect the extent of one's knee injury, weight plays the biggest role in knee joint deterioration rather than running itself. The benefits of or lack of scientifically attested gain from stretching is also covered and, among other controversial topics, how to deal with pain is also discussed (Is pain inherently part of the physical and psychological adaptation inherent to running? Should one stop training altogether, when in pain?).
All in all, Running Science provides a good, science driven synthesis of key topics of interest for runners and for those who are into the interworkings of running as a sport. It does so in accessible language and where there are medical terms, they are sufficiently explained so as to be easily understood by readers lacking specialised training. It is more of a road opener into research on running rather than an exhaustive text, for those interested in the topic.
