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?

Hopefully rowers can start to banish the preventable problem. STRESSED spelled backwards is DESSERTS.

Why delaying back swing is hard
The power phase is most effective when legs drive first and back follows yet so few masters rowers do this. Why? Timestamps 00:45 Good power phase requirements The alignment of the womens double in the photo shows that the crew hasn't used their back while having legs nearly straight. Getting into this position requires having shoulders sternwards of the hips at the catch and to use their legs first in the power phase. 03:00 Pulling with arms is easy We have a lot of practice using hands and arms in daily life. We are good at this. At the catch you want to feel the oars loaded up under the water surface. If you pull with your arms you feel this earlier. By pulling with your arms and lifting the shoulders and lifting your chin you feel the workload on the spoon. Rowing is a pushing not a pulling sport in the main. Rowing legs only is 60% of the power; back swing is 25-30% of your power and so your arms add 5-10% of your power ONLY. 06:00 Small muscles v big muscles The rowing stroke uses a range of body muscles from legs, thighs and calves through to arms and hands. In daily life we use small muscles a lot - they fire quickly when we use them in daily life. We are practiced using them. The quads and glutes are slower to activate so we have to train them - we're less habituated using these. Connecting the handle of the oars through the footstretcher is unfamiliar and you have to train it. The first activation in the power phase is the calves to push the heels down onto the footstretcher, Then the quads join in to straighten your legs. When your legs are 3/4 straight you start the glute activation - hinging to connect legs to the back. Using the glutes to sustain pressure on the footstretcher while you swing your back. If you lose pressure on the footstretcher you are no longer accelerating the boat. Your feet are the only part of your body connected to the boat. As your back starts to activate you draw with your arms. 10:00 Why delaying the back is hard Connecting to the footstretcher early in the power phase is our goal. If you take the catch with the arms or swinging the shoulders/back this is a problem. When delivering power through the stroke you can only use each muscle group once per stroke. If you swing your back to take the catch you've got no back swing to use later in the power phase because you are already leaning backwards. It also prevents you from activating your leg drive - they do straighten but not as dynamically as you should. By not activating your legs this removes up to 60% of your possible total power which is a lot. And as a consequence you probably don't activate your glutes because you aren't using your legs enough. There's a correlation between the water being slower at the catch than later in the stroke. The angle of the oar spoon is also going into the slower water at an acute angle to the side of the boat. Use the slower water speed along the slower muscles to generate that early power in the stroke. 15:00 The solution to delaying your back swing Is to train yourself to use the big muscles, learn what it feels like to activate the quads and glutes early in the stroke. Then you know what it feels like to grip the water at the catch with your feet (rather than hands or shoulders). This is the beginning point to learn how to activate big muscles first and layer the smaller muscles on top as later activations. Want easy live streams like this?
