David Frost reviews Practical and Personal Looks at Coronary Artery Diseases (CAD) in Master's Rowers - download the additional information link below. Timestamps 00:45 David Frost's journey through CAD Coronary artery calcification - men need checking after age 70 more than women. Even rowers who are known for being stoic - if you feel something in your chest, get it checked out. "You have the coronary arteries of a 92 year old" was my signal that I needed help. The Agatston Score is is a proxy for heart health. 04:30 Five things that cause inflammation - environmental stress - toxins stress - too much sunlight - smoking - exercise Inflammation in your arteries can cause an issue if you work too hard, too fast for too long. 08:00 Rowers have a higher than average incidence of atrial fibrillation (AFIB) Maybe rowers are doing themselves a disservice by training long and hard. What to do about this? 12:00 Heart age vs calendar age There are interesting heart age metrics - pulse wave velocity measure tells how elastic your arteries are. Heart Rate Variability - the higher it is the better you are recovering. David encourages masters to measure these and track their trends. Dr Churchill in Boston is studying masters rowers' aorta for ASCVD. Get a calcium CT scan - it helped David understand his condition. 18:00 A self-scan system Perceived exertion, rest and hydration are a good guide to how you are feeling each day. David is mindful of recovery as well. What age should you start getting the calcium CT scan done? For men from age 40 and women maybe 50. For the plus wave velocity test this could be done from mid life - age 40 maybe ladies a bit later. Note David is a layman, not a doctor. Rowing training is more 80% steady state and 20% higher intensity. This has trended upwards from about 60% when David was younger. As humans we are slow to recognise when our body moved into the "next" stage. The competitive mindset can make us live in denial of aging. It's not good for you to carry to much body fat - your waist to hip ratio is worth checking. 25:00 Burden or banish? David's new book Sloth and gluttony contribute to heart disease - 80% is preventable. Lifestyle measures can defer the onset of heart disease. Hopefully rowers can start to banish the preventable problem. STRESSED spelled backwards is DESSERTS.

How wide is a boat lane?
When racing, how much space do you have in a buoyed boat lane? Timestamps 00:45 Boat lane width How can you fit a wide boat like an eight into a lane and why is it that you still find yourself rowing near the buoy line? An eight is nearly 12 meters long and the rules of racing state that a standard rowing lane is 13.5 meters (44 feet) wide, with a minimum requirement of 13.5 meters for Olympic and international races, though 12.5 meters may be used in special circumstances. The lanes are marked by buoys and must remain a consistent width along the entire straight course. 02:00 Width perception The outboard from your rigger is 2 plus meters at either side. Your boat is about 6-7 meters wide with the oars. This perception problem is aggravated when you think you're closer to one buoy line. Boat position within the lane matters. A toe-steered boat has more control over the alignment but you have to keep the boat straight through the race - there's a tendency to over-steer in buoyed lanes. You have to know where the middle of the lane is. Some people forget that when you steer in one direction, you have to correct the steering to go straight after the boat is re-positioned. When the boat is straight. the middle of the hull is in the middle of the lane, you have to correct the foot steering so the boat stays in the middle after completing a manoeuvre. This relies on using your perception of the mid-point of the lane as your guide. But if you're in the bow seat, the boat doesn't pivot under where you're sitting. 05:30 The vanishing point This is where parallel lines appear to converge in the far distance. This is useful for rowers on a buoyed course. The only time you don't have a vanishing point to refer to is at the start. The human eye is sensitive to width - using the horizon vanishing point you can tell if you're in the middle of the lane. But confusion comes when you use the buoys near to your boat to align with. Buoys are every 10 meters down a rowing course, and if you think your hull is parallel to one of the buoy lines this probably means you are actually steering towards that buoy line. You need the vanishing point to correctly position the boat. 08:00 Boat position When looking around during the race (to left or right) we tend to use the buoys nearest us as a steering guide. This is a mistake. You have to adjust your width perception to take account of the tips of your blades and also to acknowledge the vanishing point to position your hull centrally. Learn to ignore the buoys close to your boat. The vanishing point is the skill to develop to help you stay in your lane.
