| - | here's a bit of reading for those of us concerned with age and possibly related balance issues. There's something in here about cell death of fast twitch muscles depending one certain gene activity and physical activity. I read until I noticed onset of brain cell death. | + | here's a bit of reading for those of us concerned with age and possibly related balance issues.

| In addition to the death of the fast twitch muscle fibres there is a decline in blood flow to the brain which is asscociated with a decrease in reaction time and affects our balance. | In addition to the death of the fast twitch muscle fibres there is a decline in blood flow to the brain which is asscociated with a decrease in reaction time and affects our balance. | ||

| - | Males peak at 24 females at 19. Between the ages of 25 to 50 muscle decreases by about 5 - 10%. At the age of 50 - 65 about 15% and 65 - 70 a whopping 25%. Most of this decrease is in the fast twitch muscle fibre. We can stay stronger in the slow twitch which is endurance...explains LG's trips to Eliza and wherever else he goes on those long excursions without tiring. Derek our oldest ski paddler up here is the same, he can paddle forever. I have no problem with distance at a moderate pace. | + | Males peak at 24 females at 19.

| The fast twitch is what we use in a surfski in rough water. Add the decline in VO2 max which provides blood flow to the brain which means less blood flow to the brain and a decrease in reaction time. So a double whammy with less fast twitch muscle fibre and decreased reaction time from the brain. Most people wouldn't notice it much but I think in a sport where balance is crucial we will find it affects us more. One of my friends in Aus complained the other day he has never dumped so much as this past year. | The fast twitch is what we use in a surfski in rough water.
