Some links in studies between sports and intense physical activity and MND/ALS though causation far from proven.
Perhaps nerve damage caused by oxidative stress under anaerobic conditions in particular? i.e. repeatedly undertaking sprinting type activity where your body needs more energy output than your lungs can immediately provide oxygen for, rather than running at a sustainable rate.
Probably not from head impacts - may explain why cross-country skiers are also possibly at increased risk despite the lack of beatings.
The flipside of course is exercise improves cardiovascular health more than the risk of MND.
