C , which helps w/ absorption of iron is necessary
Overweight Athletes
-Often engaged in sports that require large size & mass, like football, basketball, & wrestling -Athletes should be carefully assessed for risks -Athletes should have their body masses double-checked, since indiv. w/ extreme muscle mass are often inaccurately categorized as overweight -More likely to suffer from injury
Buffer Zones
-Open spaces surrounding areas of sports activity w/in a sports facility -Needed b/c athletes often leave playing area @ a high speed (sports like basketball) or may not be looking where they are going -Standards for buffer zones for all sports, like distance from windows to prevent breaking glass from injuring athletes -Sometimes danger arises when coaches or trainers use "found" space for practice activities rather than gymnasium -Should always be adequate, & should not be used for any other purpose, like equipment storage or scoring tables -Only spaces intended for athletic activities should be used for practice, & these areas should always be supervised

-Should be part of PPE for children & adolescents to determine level of sexual, dental, & skeletal maturity -Only physician/physician's assistant may assess an athlete for sexual maturity Skeletal Maturity: -Assessed by measurements of hand/wrist as well as weight/height for age. (ex) age is 14.3 & skeletal age is 15.5, expressed as 15.5-14.3=SA + 1.2 OR Chronological age: Divide Skeletal age by chrono. age -Score greater than indicates adv. skeletal maturity & score less than one indicates delay in skeletal maturity -Most common assessment tool for sexual maturity is Tanner's 5 stages of assessment, assess maturity both males/females based on direct obs. of breasts/genitals: Females: -Breast development, onset of menses, & pubic hair distribution Males: -Penis & testes development & pubic hair distribution
Treatment Chlamydia
-Should be referred for diagnostic testing & treatment -Azithromycin 1 g orally in one dose OR -Doxycycline 100 mg orally twice daily for 1 wk -Avoidance of sexual contact for 1 wk -Very important to avoid reinfection after treatment
Initial Treatment from Near Drowning
-Should be removed from water & CPR immediately while awaiting emergency transfer -Those who recover promptly & are breathing indep. should be taken to ED for eval, as physiological responses may be delayed Treatment: -Estab. ABC's -Hight flow 100% O2 w/ facemasks -Monitoring for @ least 72 hrs for respiratory, cardiac, or neuro deterioration
Minimize Effects of Travel and Jet Lag
-Sleep well night before -Hydrate prior to boarding plane, avoiding alcohol -Avoid drinking juices, sodas, caffeinated beverages, & alcohol during flight -Try to eat/sleep on schedule that coincides w/ home time , when ext. period of adjustment is not possible -Remove shoes, stretch, & walk about periodically to improve circulation -Schedule rest time during day if necessary
Prevention of Keratoderma
-Soaking feet & using callus files to reduce thickness of existing calluses -Wearing double socks to cushion sole of foot -Wearing properly fitted shoes -Applying emollients to feet/hands to prevent friction & keep skin supple -Wearing protective gloves, tape, or moleskin to protect palms from friction
Frostnip
-Superficial freeze injury that is reversible
Marfan Syndrome Traits
-Tall, thin stature w/ loose jts., w/ long bones disproportionately long -Scoliosis -Flat feet -Pectus carinatum (pigeon chest) or Pectus excavatum (funnel chest) -Long, narrow face w/ high-arched roof of mouth & crowding of teeth -Dislocation of lenses of eyes & sometimes retinal detachment, myopia -Aortic dilation (w/ risk of dissection) -Cardiac valve disorders w/ hear murmurs -Stretch marks -Abdominal/inguinal hernia -Sleep apnea (rare)
PPE: Skinfold Measurement Component
-Using special calipers is way to est. body fat & may be performed on triceps (TST), biceps, suprailiac, & subscapular areas -Actual measurement divided by standard measurement & multiplied by 100. -Males (TST) measured 11.8: 11.8/12.5=0.944 x 100= 94.4% Males (adults): -TST 12.5 mm Females (adults): -TST 16.5 mm
Strength Training & Weightlifting
-Utilize same equipment, like free weights & weight machines, but goals are diff. -Strength training aims to improve physical conditioning, while weightlifting (not recommended for children or adolescents) is a competitive sport that involves lifting max. amounts of weight There is a number of steps that should be taken to reduce safety hazards: -Exercise equipment should be checked daily & cleaned to ensure it is safe -Instruction in lifting techniques & supervision should be provided -Athletes should be advised to do warm-up & stretching exercises b4 using equipment -Use of weights & equipment should be based on age-& size-appropriate standards to prevent injury -Weightlifting requires a spotter@ all times -One or more spotters must assist w/ free-weight exercises in which the bar passes over face or head, the athlete is positioned on back, or bar is racked in front of the shoulders
Steps to Prevent Heat Loss
-Utilize wet bulb temp index, which monitors effects of humidity, temp, & solar energy to determine risks. High risk are diabetes mellitus or overweight -Provide adequate hydration: 16 oz of fluid (sports drink, not sodas) b4 activity & 8 oz every 20 mins during activity to percent thirst. Pre- and Post-activity weight measurement, w/ 16 oz for every 1 lb loss of weight -Allow time for acclimatization (7-10 days) -Monitor for signs of hyperthermia -Provide 10 min breaks @ least every hr. -Promote evaporation, change wet shirt -Provide shelter
Breast Support
-Vulnerable to breast injuries, w/ nipple the most commonly injured b/c of sensory stimuli causing erection of the nipple tissue & subsequent friction from clothing, resulting in pain & bleeding -Breasts may have contusions, abrasion, & lacerations from impact, especially in contact sports & sports where balls or other things are hurrled @ high speeds -Breast injuries have shown to increase risk of cancer -Breast supportive devices should support Cooper's lig., which suspends breasts
Safety Measures that can be Taken Against Hypothermia
-Wearing clothes appropriate for enviro., temp, & chill index, as wind & humidity increase heat loss -Doing warm-up exercises to increase circulation -Begin exercises slowly & avoid slippery surfaces -Removing wet clothes & replacing w/ dry clothes -Avoid a lot of moisture in clothing by overheating -Wearing layers that allow for ventilation -Ensuring head & neck covered, 50% heat loss is from these areas -Wearing mittens/gloves approp. for temp & conditions -Wearing moisture-wicking socks, like those made of wool or polypropylene, to keep feet dry -Avoiding alcohol, results in vasodilation, increased heat loss & impaired reasoning
Minimizing Injury: Running shoes
-Wearing improper fitted/worn out shoes is major cause of foot injuries -Should be constructed of breathable material w/ soft but sturdy midsole, good forefoot flexibility, a strong heel -Shoes should be able to support 350 to 550 miles of running, but shock absorption weakens w/ time may need to be replaced by obvious wear occurs -Shoes should be worn for @ least 10 mins to ensure comfort -New shoes should be broken in slowly (3 mile runs) & never be worn in a marathon or other race immediately after purchase
3 Zones of Injury
1) Coagulation: Usually distal, is severe irreversible cellular damage 2) Hyperemia: Usually prox, is minimal cellular damage 3) Stasis: Between two zones, is severe, but damage is sometimes reversible
PPE: BMI Assessment
BMI formula: BMI= (weight (lbs) X 703)/ Height (inch2) OR BMI= weight (kg)/Height (m2) -Indicator of obesity/malnutrition -Cannot be used alone to diagnose obesity, as types differ considerably -Women have more body fat than men Resulting scores for adults age 20 & over are by chart: -Below 18.5 Underweight -18.5-24.9 Normal weight -25.0-29.9 Overweight -30 & above Obese BMI under age 20 uses age- & gender-specific -< 5th% Underweight -85th-<95% @ risk for overweight ->95th% Overweight
Standard Protective Equipment: Sport-Specific
Baseball: -Batting helmets w/ mouth guards -Catchers: Mouth guard, shin guards, chest protector, & protective mitt Football: -Football, helmet & mouth guard; shoulder, hip, & tailbone padding; & thigh guards Basketball: -Basketball shoes (med. tops providing ankle support) & mouth guards Gymnastics: -Wrist guards, handgrips, & soft gymnastic footwear; floor pads should be in use & equipment properly padded Skateboarding: -Helmet, knee & elbow pads, & slip-resistant shoes w/ closed toes Soccer: -Shin guards & special molded cleats or ribbed0sole shoes; goal posts should be padded to prevent head injuries Volleyball: -Kneepads, protective pants, & shoes w/ ankle/arch support
Diet Modifications for Exercise
Carbo loading & protein diet mods are often used to increase storage of glycogen be4 endurance sports, & to prevent energy loss & anemia: -Intake simple carbs immediately be4 an event may increase dehydration & cause increase in insulin, thus lowering blood sugar. If activity lasts longer than 90 mins, then stored glycogen is adequate. Lasting for more than 2 hrs, then sports drinks that are 6-8% glucose may be used during event -While high carb diet (70%) should not be used to for prolonged periods, carbo loading diets often used for 3 days b4 endurance events. Shorter durations (1 day) may cause water retention & muscular stiffness -Exercise increases need for protein, & insufficient intake may result in anemia. Endurance activities require 1.2-1.4 g protein/kg of body weight. Resistance & strength activities require 1.6-1.7 g protein/kg. Protein supplements should be avoided -Pre-event meals should be0500-1000 cal. 3-4 hrs be4 event
Syphilis: 3 Phases to Disease, w/ incubation period of about 3 weeks
Primary: -Chancre (painless) in areas of sexual contact, persisting 3-6 wks Secondary: -General flu-like symptoms (sore throat, fever, & headaches) & red popular rash on trunk, flexor surfaces, palms, & soles; lymphadenopathy occurs about 3-6 wks after end of primary phase & eventually resolves Tertiary (latent): -Affects about 30% & includes CNS & cardiovascular symptoms 3-20 yrs. after initial infection
