Walkmans were popular then though. I never said that mp3s enhanced performance - music does. I doubt that the Walkmans of the 80s enhanced performance of elite athletes given the bulk but it may have encouraged more people to get out running, thus strengthening the base of the performance pyramid:
If you can provide me with some firm evidence that listening to music whilst training is more dangerous then I'm quite prepared to admit I was wrong. However, at the moment, all I've heard is anecdotal 'evidence' and in your own words, 'your experiences do not set a precedence for everyone else'.
How many world records did Heile Gebrselassie broke whilst listening to Scatman? Ridiculous?
Also, Jos Hermans (Gebrsellasie and Bekele's manager) broke 2 one hour world records whilst listening to 'tempo tracks'. Music has also been used with boxers involved in world title fights - are they not elite level athletes?
That generalisation is ridiculous.non elite runner who cant necessarily motivate themselves fully
