1 1 Don Arthur, MD Emergency Medicine Physician Rider AND RIDING SMART

2 2 You can’t win without bagging the BIG points. You can’t win without the REST BONUS. You can’t win unless you ride a LOT. Even if you ride a LOT, you can’t win unless you ride SMART. The “Secrets” Endurance Rallying

3 3 Computing Power Fatigue Debt Sleep restores the brain’s chemical balance Wakefulness develops a sleep ‘debt’ Needs are individual and genetic Cycle is normal and cannot be changed Lack of sleep has a cumulative effect We cannot ‘bank’ sleep Sleep & Fatigue “M ore than any other factor, a winning ride almost invariably correlates with total miles ridden. “N ever forget, however, that fatigue can easily take it all back.” Bob Higdon

4 4 Our internal clock controls sleep-wakefulness cycle Tries to keep us on a ‘normal’ 24 hour cycle Synchronized to light (day) and dark (night) cycles Mid day urge to sleep is normal and can help you Sleep Sleep Need Sleep Urge “Normal” 12 NOON Circadian Rhythm

5 5 Yes… and everyone’s internal clock is unique Can easily adapt to sleep cycle shifts Adapts to three time zone shifts in as little as one day Need an additional day for each time zone shift over three Can adapt to work ‘shift’ changes – but slowly (days or weeks) But we cannot decrease our overall sleep need Sleep Sleep Need Sleep Urge “Normal” 12 NOON Can You Change Your Cycle?

6 6 Sleep Need Sleep 12 NOON Sleep Urge Sleeping less than normal results in accumulation of a sleep debt Debt lasts until rest fulfills normal sleep needs and repays the debt Disturbing the Rhythm 8 Awaken early 6

7 7 Less experienced riders are at greater risk! Sleep Sleep Need 12 NOON Gradual and insidious You may not be consciously aware – especially if engaged in high skill or high tempo activity Effects are modified by: Individual task skill level Level of training/experience Fatigue Effects

8 8 “How did I get in this lane?” Microsleeps Variable and unpredictable lapses in full consciousness Can last a few seconds Open-eyed sleep, paralysis, blurred vision, or other effects Victim is unaware except for a vague feeling of missing time May occur during periods of otherwise ‘normal’ functioning At 70 mph, rider covers 103 feet every second! You’ve had a microsleep if… ?

9 The Slowing Phenomenon Brain’s ability to process information and perceive speed Riding speed slows Faulty appreciation for speed Decreasing ‘computing power’ Faulty appreciation for speed Decreasing ‘computing power’ “Ummmm… Hey Don, the speed limit here is 65.”

10 10 Decreased performance  slower thinking Reduced vigilance Loss of situational awareness Impaired decision-making  Tend to choose uncomplicated options ‘Fill in’ perception gaps – especially at night Impaired long and short term memory Task fixation and slowed reaction time You know you’re tired when you try to put drops in your eyes and miss. You know you’re REALLY tired when it’s because you’re still wearing your glasses. You know you’re tired when you try to put drops in your eyes and miss. You know you’re REALLY tired when it’s because you’re still wearing your glasses. Dangerous Mental Changes

11 11 Psychological changes Sleep becomes major subconscious focus Mood slowly degrades and interferes with socialization Motivation declines  faulty decisions Eating and drinking tasks are ignored Inhibitions wane  impatience, frustration, anger Personal hygiene ignored Unexplained refusal to recognize sleep deprivation Impaired ability to take corrective action Deepens fatigue and increases danger The greater the fatigue, the greater is our tendency to underestimate the fatigue burden and magnitude of the drive to sleep. This adds to the danger of unrecognized fatigue effects. The greater the fatigue, the greater is our tendency to underestimate the fatigue burden and magnitude of the drive to sleep. This adds to the danger of unrecognized fatigue effects. Fatigue Manifestations

12 12 Socialization and physical activity Enhances alertness while engaged in activity But… you will be more prone to sleep afterward Prescription medications Effects may be affected by other riding factors May increase susceptibility to problems while riding Consult your primary care provider Other drugs May improve wakefulness but only for very short periods Do not enhance long term (days) performance Significantly decrease performance after dose wears off There is NO place in any sport for stimulant drugs. PERIOD. There is NO place in any sport for stimulant drugs. PERIOD. Countermeasures JUST SAY NO! JUST SAY NO!

13 13 Sleep Need Sleep Timing NOON Sleep Normal circadian rhythm favors sleep at two times Try to time sleep to coincide with circadian rhythm Light and other cues lessened at night  increased risk Fall asleep more quickly Nap effectiveness will be enhanced Sleep Sleep Need SleepNap Sleep Urge NAP

14 14 Resting – naps v. prolonged sleep Repetitive ‘missed sleep’ has cumulative effect Prolonged sleep is necessary to repay fatigue debt Some sleep is better than no sleep Naps provide significant recuperation but not as good as prolonged sleep Any sleep longer than 5 minutes is beneficial Waking after more than 45 minutes but less than 2 hours  sleep inertia Two hours of continuous sleep ensures complete sleep cycle Grogginess during sleep inertia is dangerous! Prophylactic naps help Sleep timing Combine with gas/food stops… or not? Rest without sleep does not pay fatigue debt Sleeping or Napping

15 15 Deep sleep phases Brain function very slow Difficult to awaken Inertia if interrupted Deep sleep phases Brain function very slow Difficult to awaken Inertia if interrupted Light sleep Jerky movement Easily awakened Light sleep Jerky movement Easily awakened 40-50% of sleep time No eye movement Brain function slows Easily awakened 40-50% of sleep time No eye movement Brain function slows Easily awakened Moderately deep sleep Dreaming phase Erratic heart rate and breathing Easily awakened Moderately deep sleep Dreaming phase Erratic heart rate and breathing Easily awakened STAGES 3 & MINUTE SLEEP CYCLE REM = Rapid Eye Movement – the stage of sleep where dreams occur The Sleep Cycle “DON’T WAKE ME UP” Stages of Sleep “DON’T WAKE ME UP” Stages of Sleep Nap for 5-45 minutes to avoid sleep inertia. Sleeping more than 2 hours provides a full sleep cycle. Nap for 5-45 minutes to avoid sleep inertia. Sleeping more than 2 hours provides a full sleep cycle.

16 16 Be physically and mentally comfortable Shelter is better than open air Police guarded rest stops are best Company is good Use a ground cloth or pad to keep dry Stay away from pet walking areas Beware of ants and other creatures Leave your helmet and riding suit on Remove your ear plugs Don’t wake others with your Screamin’ Meanie ® Yes, you can sleep while resting on your tank bag There is no substitute for sleep. “REST TO GO FARTHER.” There is no substitute for sleep. “REST TO GO FARTHER.” Where to Sleep

17 17 The Iron Butt Hotel

18 18 Clear your mind Don’t keep planning your ride If something is bothering you, fix it! Develop a bedtime routine and stick to it Yoga, meditation, reading Train your mind to anticipate sleep Avoid activities which require complex thought Have everything packed and ready to go when you awaken Turn your phone off Pay your bill ahead of time Set your alarm and ask for a wake-up call Have your bike gassed up and ready to ride Have something to eat and drink ready for the morning Sleep where and how you’re comfortable and fall asleep easily Roommate? Find one with similar/complementary habits How to Sleep the Night Before Overcoming Pre-Rally Excitement

19 19 Carefully consider potential riding impact Chronic illnesses Predisposing conditions Carry a card with emergency information Name, address, phone numbers Next of kin and how to contact Significant health history Medications and allergies Health insurance information Vehicle insurance and towing information Make an ICE entry in your cell phone contacts Put a sticker on the back of your driver’s license Take extra medication (in safe and dry place) Prevention is better than treatment When in doubt, talk with your primary care provider Preparing for the Ride

20 20 Can you find your gear… In the dark? In the rain? Can you find your gear… In the dark? In the rain? Begin well rested Maintain physical fitness Eat properly Small, balanced meals Easily digested, low bulk foods Afternoon snack to counter circadian dip Avoid caffeine, alcohol, and tobacco Participate in several small rallies before “the big one” to develop a successful routine and confidence. Personal Preparation

21 21 Consistent systematic packing Communication equipment (phone cards, too) Ergonomics – form and function Comfortable seat that fits YOU If you’re worried about your tires, change them! Tools and tire repair kit – know how to use them! Can you pick it up? “SKERT” Bike Preparation Prepare your bike to eliminate variability

22 22 Know your limits ahead of time and stick to them. Severe time constraints Bad weather Excessive heat or cold Unfamiliar roads Monotonous scenery Extended night riding Increased threats – wildlife and traffic Riding conditions beyond the rider’s ability Complex tasks required while riding Distractions – mechanical or personal problems YOU’RE LATE! Eliminate Riding Stressors PLAN YOUR RIDE. RIDE YOUR PLAN.

23 23 Helmet – proper fit, full face, liner Windshield – laminar flow Eye protection UV filtering sunglasses Prescription lenses/bifocal inserts Hearing protection Skin and lip protection Powder to prevent chaffing Courtesy: Paige Ortiz Sun Wind Dryness Moisture Temperature Vibration Noise ENVIRONMENATL EFFECTS Environmental Stressors

24 24 Full body protection of your choice Waterproofing – including gloves and boots Ballistic contact point pads Make sure everything is ‘broken in’ Heated clothing – vest at least Evaporative cooling garments The perennial undergarment debate… Clothing

25 25 Water loss from heat exposure – primarily sweating Normal vapor loss from lungs Normal ‘insensible’ water loss from skin Increased water loss during heat exposure Keep skin covered Use cooling methods Significantly affects mental and physical functions Can accelerate development of fatigue Accentuates fatigue effects Many symptoms mimic fatigue Dry mouth, headache  nausea, muscle weakness Increases risk for heart and circulation problems Especially when taking some medications Dehydration

26 26 Stay ahead… DRINK before you need to Water AND electrolyte (salt) solution Sweating causes loss of water and electrolytes Need to replenish BOTH Low salt levels can be harmful Read the labels Amounts of electrolytes vary May contain carbohydrates (sugar) Avoid caffeine or alcohol for hydration Both cause water loss by increasing urination And this can accelerate dehydration Rehydration

27 27 Carbohydrate (sugar) in drinks can be dangerous for diabetics Can raise blood sugar level acutely May result in rebound decreased blood sugar May increase water output through urine Most athlete supplements contain sugar + SugarNo Sugar Contains necessary electrolytes No carbohydrates/sugars Add to your water bottle Contains necessary electrolytes No carbohydrates/sugars Add to your water bottle For Diabetics

28 Caffeine is not a substitute for rest! Should be avoided prior to an event – habituation Can be used ‘strategically’ to improve alertness Mental awareness improved by mg Peak effect seen in 30 minutes, lasts 3-4 hours Don’t consume prior to anticipated rest – disturbs sleep Will increase urine output! The ‘Caffeine Nap’ Drink a caffeinated beverage just before a nap The caffeine will be absorbed during the nap Caffeine effects will manifest upon awakening Caffeine is a drug – use it wisely! Caffeine

29 29 Remember, caffeine is a diuretic! Effective dose = mg Caffeine Sources Grande 330mg 10 ounce 130mg 8 ounce 60mg 8 ounce 5-25mg 2 ounce 207mg 8 ounce 80mg 12mg/ Piece 200mg/ Tablet 9mg/ Piece 12 ounce 55mg* 12 ounce 140mg 12 ounce 30-45mg TEA 400mg/ Packet * NOT IN CANADA

30 30 “Regain the feeling of energy and mental alertness with 5-Hour Energy Drinks. It’s better because you can actually feel it working. It starts with a tingle, a sudden rush, then KAPOW. Grogginess is gone and you’re running on all cylinders. Your mind is alert and focused. Your body is ready for action. “5-Hour Energy Drinks provides a boost of energy and mental alertness that lasts for hours – with no crash. That’s because 5- Hour Energy is packed with B-Vitamins, enzymes and amino acids.” “Regain the feeling of energy and mental alertness with 5-Hour Energy Drinks.

31 31 Contains 207mg of caffeine. (“…as much as a cup of coffee”) … and a whopping dose of Niacin (Vitamin B3) which causes dilation of blood vessels and a flushed feeling, giving the impression “It’s working.” These effects may increase water and heat loss due to blood vessel dilation. Side effects include nausea, vomiting, dizziness, insomnia, arm and leg numbness, rapid heart beat. 5-hour Energy Drink Other Ingredients: Purified Water; Natural and Artificial Flavors; Sucralose; Potassium Sorbate, Sodium Benzoate and EDTA (to protect freshness).

32 32 Know when to stop. Stop before you need to Stop to go farther! Have a routine for stops. Gas… log? Food Et cetera Get gas before you need to. Separate gas from rest stops? Avoid high speeds. Greatly increases fatigue Greatly increases risk Consistency wins! Stay away from trucks! NO RIDE IS WORTH YOUR LIFE! Ride Safely

33 33 You’re four times It’s hard to more likely to have concentrate on a road accident two things when you’re on at the same time. a mobile phone. Distracted drivers …are out to kill you! Be On The Lookout!

34 34 Enjoy the Ride!
