5 What Really is Functional Training? Function is purpose. When we ask what an items function is, we want to know its purpose. Think of functional training as purposeful training. Functional training is literally training muscles based on their function! From a scientific perspective it is the application of functional anatomy to training Function is purpose.

6 Movements, Not Muscle Groups Forget bodypart divisions- chest and back etc. Think of movement action, not muscle group Learn basic anatomy Learn true functional anatomy, it will change the way you think.

7 PAY ATTENTION TO ANATOMY If you dont get this nothing else makes sense. If you didnt pay attention, go back and study If you dont get this nothing else makes sense. If you didnt pay attention, go back and study

8 The Basics Ligament- bone to bone, noncontractile, slow to heal, slow to adapt, Ligaments provide joint stability and proprioceptive input ( where the joint is in space) Made up of varying degrees of collagen ( tensile strength) and elastin (flexibility and recoil) Innervated by nervous system Ligament- bone to bone, noncontractile, slow to heal, slow to adapt, Ligaments provide joint stability and proprioceptive input ( where the joint is in space) Made up of varying degrees of collagen ( tensile strength) and elastin (flexibility and recoil) Innervated by nervous system

9 Muscles Think of muscles as elastics or springs that connect bone to bone Muscles move or stabilize bones Unlike ligaments muscles have the ability to lengthen and shorten Tendon connects muscle to bone Tendons are the anchors for contraction and also have poor blood supply and heal slowly Think of muscles as elastics or springs that connect bone to bone Muscles move or stabilize bones Unlike ligaments muscles have the ability to lengthen and shorten Tendon connects muscle to bone Tendons are the anchors for contraction and also have poor blood supply and heal slowly

10 Muscle Fiber Types Type 1- Slow Twitch, smaller, produce less force, more mitochondria, slower to fatigue Type 2- Fast twitch, opposite of above in all regards Type 1- Slow Twitch, smaller, produce less force, more mitochondria, slower to fatigue Type 2- Fast twitch, opposite of above in all regards

11 Types of Muscle Contraction Concentric- shortens Eccentric- lengthens Isometric- static, no change in length Curl example Concentric- shortens Eccentric- lengthens Isometric- static, no change in length Curl example

12 Time Under Tension The length of a set =TUT Set is a group of repetitions A rep is expressed by tempo Tempo is described by three numbers - Eccentric ( lengthen) - Pause ( isometric) - Concentric ( shorten) Time under tension is the time it takes to complete a set The length of a set =TUT Set is a group of repetitions A rep is expressed by tempo Tempo is described by three numbers - Eccentric ( lengthen) - Pause ( isometric) - Concentric ( shorten) Time under tension is the time it takes to complete a set

13 Response Muscle response is a function of time under tension ( tempo-rep, TUT-set) For size ( hypertrophy) TUT must be sec For strength less than 1-20 sec. Muscle response is a function of time under tension ( tempo-rep, TUT-set) For size ( hypertrophy) TUT must be sec For strength less than 1-20 sec.

14 Length Tension Length tension relationship There is an optimum length at which a muscle can produce its greatest force. A muscle must be lengthened to be able to shorten effectively Max force is at normal length Hamstring example Length tension relationship There is an optimum length at which a muscle can produce its greatest force. A muscle must be lengthened to be able to shorten effectively Max force is at normal length Hamstring example

15 Velocity Velocity is displacement/ time Acceleration is change in velocity Sport is about acceleration not velocity Sprints measure acceleration, not speed 4.5 forty? Is that velocity? 40 yds in 4.5 sec. Velocity is 8,8 yds/sec Displacement is 40 yds Velocity is displacement/ time Acceleration is change in velocity Sport is about acceleration not velocity Sprints measure acceleration, not speed 4.5 forty? Is that velocity? 40 yds in 4.5 sec. Velocity is 8,8 yds/sec Displacement is 40 yds

16 Force Velocity Curve Muscle has an inherent capacity to adjust force to match load. This is what separates it from simple elastic contractions. ( Edman in Komi p 105) Max load= minimal velocity-- (strength) Minimal Load= high velocity- (power) Training must be at various loads and speeds Muscle has an inherent capacity to adjust force to match load. This is what separates it from simple elastic contractions.

17 Stretch Shortening Cycle Finger Trick? Muscle has elasticity but, not simple elasticity SSC= the natural combination of eccentric lengthening progressing into concentric shortening Plyometrics are intended to facilitate this process ( incorporating Force Velocity) Finger Trick? Muscle has elasticity but, not simple elasticity SSC= the natural combination of eccentric lengthening progressing into concentric shortening Plyometrics are intended to facilitate this process ( incorporating Force Velocity)

18 What Are Plyometrics?

19 Eccentric to Concentric Switching Plyometrics are designed to use the stretch shortening cycle to effect the force velocity curve. In other words, they teach you to move heavier loads faster.

Increased strength yields increased ground reaction force For every action there is an an equal and opposite reaction This is the key to strength training.

57 Power

58 Ground Reaction Force The effect of action- reaction on the body. Every step you take is subject to gravity (how much you weigh) and momentum ( how fast you are moving). Ground reaction forces move up the chain and cause all our injury problems. The effect of action- reaction on the body.

They can no longer stand from the toilet ( lack of leg strength) They can no longer wipe ( lack of trunk rotation) Standing exercise is the ideal but, how do we get there?
