Slide 4 Overview Part One 1. Considerations based on athlete differences in size and shape. 2. Considerations of rowing technique. 3. Selection procedures to find the right pieces. Part Two 1. Rigging. 2. Training strategies to bring crew together. 3. Traps to avoid. Slide 5 1. Athletes Size and Shape Stroke Length, not height is important. All athletes must row the same length stroke or timing will be off. The boat is moving the same distance. Slippage of blade is not a desirable variable. Slide 6 Athletes Size and Shape Cont. Physical Characteristics affecting Stroke length Length of limbs. Ratio of leg bones. Ratio of Torso to Legs. Shape and thickness of trunk. Slide 7 Athletes size and shape Drawings go here Slide 8 Athletes Size and Shape Cont. Beth K 59 and Cicely M 59 Slide 9 Athletes Size and Shape Cont. Slide 10 2x video Slide 11 Rigging Rigging Adjustments Lowering feet can help with longer shins and allow greater compression. Stretcher angle can help with less flexible ankles to achieve greater compression Raising height can allow greater length of pull. Oar Length/ Use of CLAMs Slide 12 Motion of the Center of Mass While Adjustments to the oar can allow a rower with shorter inboard length to match length at the blade, it is difficult for athletes to row well together when their mass is travelling too great a difference over a stroke cycle. May be an inherent inefficiency??? Cant meet ideal ratio if they arent at the same ratio. Very hard for a shorter slide to follow a longer slide as the rower has to go slower. Slide 13 Motion of Masses Adjusting motion Length of Slide. Compromise to ideal compression More upright position w/ greater compression results in great movement of mass. Less compression and more swing leads to less movement of mass -- more efficient technique (see Fisa Coach). Slide 14 2. Considerations of Rowing Skill Technical flaws that make the rower less effective Technical flaws that make the boat less effective Use of wrong musclesSet: Initiating with back (loss of leg drive) Body control Handle heights Release Blade entryRushing the slide Speed of transition to driveLack of body control at transitions Many many more.Others? Continuum Slide 15 Consideration of rowing skill All skills are situational Discipline (sculling vs sweep). Boat Class Rate/ Speed. Seat in Boat. Length of event (seat race). Slide 16 Considerations of rowing skill Importance of Transitions and drive speed. Speed of motion is trainable and therefore specific. Power = Force x Velocity (more later). All athletes need to match transition speed to be optimally effective. A slower athlete will not be able to apply force effectively chasing the drive. A quicker athletes skills are somewhat wasted in a crew of slower athletes (especially larger, slower athletes). Slide 17 Whats at Stake?

This will affect how I do: Selection and seat racing! Training Drills Slide 23 Rowing Skill cont. A single less skilled athlete has a greater negative effect on a crew than one more skilled rower can have on a less skilled group. Mistakes make all others less effective. Added skills may have some positive long term effect (blade work example), but can do little to help overall boat speed. Putting a skilled rower with less skilled athletes may lead to bad habits. Risk of injury (left alone on drive). Slide 24 Selection Foundation is Evaluation Power/Fitness Ability to apply on the water (Technique) Ability to row with others Slide 25 Selection Establish Timelines How much time to allow for athlete development and skill acquisition. How long will selection procedures take? How much time to allow crew to come together. Can you use early season racing? Control your message about what lineups mean. Slide 26 Selection My Strategy: Identify prime movers, allow them to establish dominant rhythm. Select for best complements. Know your most important goal. YNC 4 x 2k over 3 days. Club Nationals 10 x 2k over 5 days. Top boat or fast crews? What are team goals? Slide 27 Selection My Model Erg Evaluations Seat Racing Time Trials Slide 28 Selection Erg Evaluations Erg Opportunities: earn you a seat race. Not just 2ks Power profile. Know their relative strengths over a range of distances. Repeat sets (4 x 1250). How do they respond to multiple pieces. Fitness is distinct from power. Power = force x velocity (erg doesnt tell you how) Rate Length Must use Weight Adjustment or factor Magic Number (watts/KG^(2/3)) Slide 29 Selection Seat Racing Limitations Boat class factors. Seat racing in smaller boats Favors specific skills Favors specific (slower) drive speed. Seat racing in big boats Chaos. Crews will perform to lowest common denominator of skill (how deep is your team technically). Slide 30 Seat Racing Limitations cont. Format Factors Distance and repetitions will favor certain fitness profile of athletes. Stroke rate. Coxed? Slide 31 Seat Racing Limitations cont. Inherent limitations Favor athletes who adjust quickly. Favors specific combinations/ comfort level. How does proximity effect performance? Know your athletes! Coxns effect. Slide 32 Selection Seat Racing Strategies Variable Stroke rate (40-30-20-10). Variable format. Seat race strong but less fit athletes later in set. Control boat. Three or more crews. Watch for patterns Control pieces (first couple w/ no switches evaluate variability). Never final selection and they know it! Slide 33 Time Trials and Line Up Evaluations Abilities are situational. I am selecting for seats. Athletes perform very differently in specific seats. Skill seats: Seven seat follow by feel, sound; steady. Bow pair Finishes, balance. Six seat rush, catch support. Chemistry 4 piece format. Evaluate using practices pieces (every day is a seat race). Evaluate using early races. Slide 34 Traps Selecting too early Less skilled rowers with more talent may improve forcing dilemma of late season switch. Time together favors selection. Motivation? But Selecting too late Crew isnt left with time to come together. Time to establish boat goals, values, behaviors. Slide 35 Joy of Sculling 2011 Ethan Curren Director of Coaching Education Head Coach, Junior Women Community Rowing, Inc Slide 36 Rigging Rigging Adjustments Feet and Seat Lowering feet or adding butt pad will help athletes with longer shins to allow greater compression. Raising feet may shorten stroke, but allow for more power from legs. Stretcher angle can help with less flexible ankles to achieve greater compression Slide 37 Rigging Raising height can allow greater length of pull. Oar Length/ Use of CLAMs Adjusting leverage can help compensate for length differences. Often rowers with shorter strokes also have more muscle mass and can handle a bigger load. If they dont, be careful about loading. Longer limbed rowers are already dealing with a relative mechanical disadvantage (shorter limbs work better in weight room). Slide 38 Motion of the Center of Mass While Adjustments to the oar can allow a rower with shorter inboard length to match length at the blade, it is difficult for athletes to row well together when their mass is travelling too great a difference over a stroke cycle. May be an inherent inefficiency??? Cant meet ideal ratio if they arent at the same ratio. Very hard for a shorter slide to follow a longer slide as the rower has to go slower. Slide 39 Training them to come together Define your Style Make sure they know it. Attention (dont distract). Intention (Athlete should understand goal and why). Slide 40 Motion of Masses Adjusting motion Length of Slide. Compromise to ideal compression More upright position w/ greater compression results in great movement of mass. Less compression and more swing leads to less movement of mass -- more efficient technique (see Fisa Coach). Slide 41 Training them to come together Establish a uniform recovery first Organizing point of the stroke Finish Pause? Bodies over? Set up and speed into the catch will determine drive. Slide 42 Training them to come together Direct attention to body spacing Distance of head, shoulders. If bodies move together, catch and finish timing can be established quickly. If blade timing is established first, it can take a long time (if ever) to change rhythm. Slide 43 Training them to come together On water drills. Pause Drill define a gathering point beware timing to pause position be aware of body proportions. Longer arms take longer to extend. Longer torsos take longer to bodies over Are you allowing athletes to compensate for differences? pause to oar angles? Slide 44 Drills Teach rowers to be adaptable and they will be better at making adjustments Ratio Drill 15 strokes each at ratio 5:1, 4:1, 3:1, 2:1, 1:1 all at 75% pressure. Short strokes. Pick drill full boat. 1/2 and 3/4 slide Slide 45 Drills Speed work. Hones handle quickness. Builders Starts Slide 46 Drills Train them to sense the timing Auditory Clues Tap Drill. Tap handle on gunnels at perpendicular. Slap. Flat blade strikes the water at the catch. Boat feel Pulse drill. Half crew at pressure others paddling and feeling then join in support. Slide 47 Training them to come together Erg Excercises Sliders. Erg together, watch handle speed. Tape handles. Match pairs facing. Look through more experienced athlete in mirror (Bill Manning). Slide 48 Taped handles Slide 49 Training them to come together Long Term Strategies Pairings. Small boat partners Seat race pairs. Core groups. Core four Race in smaller boats. (Winning pair history) Manipulate ergs in winter. Develop expertise! Allows rower to be effective in more situations so you can put your best athletes in the boat. Small boats. Switch Sides. Sculling. Quickness. Slide 50 Traps Rowers who look pretty What are you looking at? Do you know you tendencies? Easier to see posture than blade work, particularly in the water. Does it really matter? Slide 51 Traps Rowers who cant sustain technique How do they hold up under fatigue? How do they hold up on race day? How do they respond to conditions? Slide 52 Traps The Rower who you just cant wait until she gets it Will she ever? How does having her in the boat affect the quality of practice? How does it effect morale? How does it effect the rower whos out? What message does it send? Slide 53 Traps The rower who just wants to make the boat. Your own foibles: I can fix her! reward performance, not potential. Need for control: let athletes take ownership, dont tinker too much as the competition approaches (unless you need to). Slide 54 Traps Technique Timing the feather, not the release. Drills that dont allow for athletes to adjust to each other (careful when you use them).
