Materials Things often used Materials Equipment uses many different types of material ○ Plastic, velcro, rivets,, steel/ aluminum buttons etc. As we look into other forms of equipment, we need to start to look at what is being used and why. We have discussed FOAM previously Neoprene Neoprene Advantages: Disadvantages: Tough material Allergies Maintains warmth Too hot for some Great compression Bulky excellent memory No breathablity Form fitting No water absorption Epix/ Bioskin/ Trilaminate Epix/ Bioskin/ Trilaminate Advantages: Disadvantages: Thin Not for all people (very conforming, so think location and Light body type) Great compression Too high compression (size? Breathable mobility?) Excellent memory Cost Hyoallergenic Cool Flex/ Dry Tec Cool Flex / Dry Tec Advantages: Disadvantages: Breathable Low compression (on its own) Comfortable Low Memory/ Conforming Elastic Evoshield Evoshield Advantages: Disadvantages: Multiple products/ pads across Can be bulky (Takes time to adapt various sports to new fit) Combine plastic with other Predetermined sizes and shapes material (neoprene/ polyester etc) Once moulded, cannot be ‘refit’ for multiple Can be formed to individual athlete for best fit Thermoplast/ Sand Splint Thermoplast/ Sand Splint Advantages: Disadvantages: Moldable/ Re-Moldable so once an Can be costly (Depends on athlete is done, can be used for dimensions) another Needs to be cut, so measure twice Cleans easy and cut once Can be cut to fit based on needs Needs to be filed at edges Can be perforated for breathability Excellent strength-to-weight ratio (light but strong) Compression Gear Compression Gear Provides compression (duh…) to muscles while wearing gear Can be worn during exercise or after as a recovery method Studies tend to find evidence that compression prolongs endurance, perceived level of exertion, muscle temperature etc. (These look like perfect places to get exam questions) ○ Like this one... ○ And This One ○ And finally....(but there are lots more) Level of compression can be different over time (wear and tear) or by product and may affect purpose (ie. running sock vs diabetic sock) Compression Gear Advantages: Disadvantages: Can be worn as part of the Level of compression varies from equipment or as recovery attire product to product and over time May decrease recovery time and Benefits may be more promote muscle healing from psychosomatic vs actual (more rigorous activity research needed) So. Many. Colours. Medical grade compression requires a Dr. DX/ Script (diabetic, varicose vein etc) Materials Materials all have a time and place Must balance comfort, fit, restriction, and psych readiness (will this make the athlete feel invincible?) Mid-term Written Feb 10 (1 wk!) and Practicals Feb 18th & 20th (After Family Day) ○ Written in class (50 min) Material up to Feb 3 (Will be done via SLATE online IN CLASS) ○ Practical will be helmet/ shldr pad fitting/ maintenance/ face mask repair/ possible shoe evaluation, gait Come in, pick a card, do what it says, get marks, leave
