KIN 3304 1nd Edition Lecture 33Outline of Last Lecture I. Review for finalOutline of Current Lecture I. Review for final 2Current LectureI. Review for final 2a. Know the Nerve Impulse picture i. Steps in Initiating Muscle Contraction1. Ach Released2. Action Potential reaches T Tubule3. SR releases Ca2+4. Active-Site exposure; Cross bridge formation5. Contraction begins6. Ach removed by Ache7. SR recaptures Ca2+8. Active sites covered9. Contraction ends10. Relaxation occurs; return to resting lengthb. Strength: Absolute vs. Speed vs. ExplosiveThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.i. Absolute Strength1. Time is not a factor2. Measure of max volitional muscle force3. How much force you can applyii. Speed Strength1. Relatively no or little resistance2. Ex. Throwing a baseballiii. Explosive Strength1. Ex. Sprinting up hill2. Ex. Vertical jump3. Ex. Clean and Jerkc. Repetitive/Dynamic vs. Brief Maximal Tensioni. Repetitive Effort1. More sets which equals more reps2. Not more repetitionsii. Brief Maximal Tension1. Lifting something very heavy for a short moment of timed. Strength Endurancei. Ex. Running across Sahara deserte. TQ: Know that increases in strength = neuronal apparatusf. Know the table:Load (% of 1RM)Reps per set Optimal Total RepsRange of Total Reps55-65% 3-6 24 8-3070-80% 3-6 18 12-2480-90% 2-7 15 10-2090+% 1-2 4 1-10g. Someone starts a marathon. What energy system are they using? All of them, just one is more predominanth. Know the ATP, ATP-PC, etc. charti. On the ATP, ATP-PC chart, which one is missing? i. ATP because it is very fastj. Rigor Mortisi. When you’re stiff and run out of ATPii. Muscles are tenseiii. Tissues decompose, so Ca2+ is just released and when you run out of ATP, you cannot uncontractk. Fill in hormones chartl. Label the sarcolemmam. Know the image of the triad, SR, T Tubulen. Meth users have an epinephrine rusho. Know the Angiotensin Pathwayp. Know about ACE Inhibitorsq. Know concentric, eccentric,
