1 HORIZONTAL JUMPS LONG JUMP / TRIPLE JUMP Presented by Ian Dube Horizontal Jumps Chair USATF VP USATFGA Managing Director INSIDE THE OVAL TV ian@insidetheovaltv.com (770)

2 FUNDAMENTALS OF JUMPING Aims Maximize measured distance or height TJ maximize the distance of three consecutive jumps Biomechanical Aspects (a)velocity at take off (b) Angle of take off (c) Height of COM at take off

3 FUNDAMENTALS OF JUMPING Movement Structure 1. Approach 1. To achieve desired velocity 2. To achieve accuracy in the takeoff 3. To achieve perfect body positions for takeoff 2. Takeoff 1. Good posture 2. Large ranges of motion (hips 3. Displacement: Effective stride length should be conserved as the athlete moves through these steps 4. Conservation of horizontal velocity final four steps (Priority) 5. Dorisflexed ankle (Last two steps) 6. Rolling foot action upon contact to ground 7. Body should move in front of the foot while in contact with thee ground 8. Penultimate step is the 2 nd to last which sets up an effective takeoff

4 FUNDAMENTALS OF JUMPING 1. Flight 2. Landing

5 FUNDAMENTALS OF JUMPING Characteristics of a good approach It s fast (Maximize Horizontal Velocity) It s accurate and consistent It prepares the athlete for a powerful take The athlete must run in a hips tall position at take-off (rolling contact dorsiflexed foot) At take off ground contact time should equal.15 secs. males /.17 secs. Females The knee of the free leg should exhibit a forceful upward swing from the hips The athlete should exhibit triple extension

6 FUNDAMENTALS OF JUMPING Teaching progression Take off from a running approach Movements in the flight phase Landing Teaching Points Inverse relationship between acceleration and deceleration Active foot plant with the entire sole at take off. Forceful lead leg action at take off Triple extension of the ankle, knee and hip joints at take off

7 FUNDAMENTALS OF JUMPING Training inventory Sprint skills of a sprinter Acceleration Runs Loads Exercises Distance Reps Sets Load Level Acceleration Runs Meters High

8 FUNDAMENTALS OF JUMPING Training Inventory cont d Plyometrics Standing Bounds Short approach Bounds Bounding from a fast approach Bounding uphill (Crown of football field) Bounding for distance (i.e. 5x10 bounds for distance) Bounding for speed (i.e. 5x30m bounding timed) Exercises Distance Reps Sets Load Level Bounding from a standing start m Low Bounding from a short approach Bounding from a fast approach Bounding uphill / Resisted m m m Medium High Low

9 FUNDAMENTALS OF JUMPING Training Inventory cont d Single leg hops Load Exercise Distance Reps Sets Loading Hopping from standing start m Medium Hopping from a short approach m Medium Hopping from fast approach m High Rhythmic Hopping m Medium Hopping up stairs m Medium

10 FUNDAMENTALS OF JUMPING Training Inventory cont d Hurdle jumps Exercises Distance Height # Reps Sets Loading Ankle flips m cm Low Dbl. Legged m cm Medium Repetitive take offs 3-4m (1 Step) 7-8 m (3 Steps) cm Medium Single Leg take off with take off leg landing 3-4m (1 Step) 7-8 m (3 Steps) cm High

11 FUNDAMENTALS OF JUMPING Training Inventory cont d Games A variety of boxes and other objects are set up in a marked off area. The athletes move freely within the area jumping over each object as they come to it. The jumping movements can be varied (landing on the take off leg, swing leg or both legs) An obstacle course is set up around a square area. A number of hunters are designated. Their task is to capture the other athletes. Captured athletes must run a lap of the obstacle course before being allowed back inside the square. The goal of the hunters is to get all the other athletes out of the square at the same time An obstacle course is set up for each team. The members of each team are split into two groups which are positioned at opposite ends of the course. The first runners completes the course and starts the second runner with a hand slap, etc. The race is over when all runners are back to their original position

12 LONG JUMP

13 LONG JUMP

14 LONG JUMP CONSIDERATIONS Running Mechanics Smooth and consistent acceleration Proper desired acceleration and maximal velocity mechanics are crucial because they effect accuracy and body position at take off

15 LONG JUMP CONSIDERATIONS Visual Focus during the Approach Jumpers adjust inherently the length of their final steps in order to insure accuracy at take off Checkmark System Athletes Check Point Coaches Check Point

16 LONG JUMP CONSIDERATION The Penultimate Steps Lowering of the athletes COM (Minimizing horizontal velocity loss) Body moving well past take off foot establishing a strong swing of the free leg

17 LONG JUMP CONSIDERATIONS Takeoff Actions Takeoff foot should land slightly in front of the COM Reduction of horizontal velocity should be mitigated as much as possible Takeoff should be forward and upward Arms should exhibit a split and forceful swing Free leg should exhibit a similar powerful upward swing

18 LONG JUMP CONSIDERATIONS Flight Forward rotation is controlled Torso should be upright Styles Hang Technique Hitch-Kick Technique

19 LONG JUMP CONSIDERATIONS Landing Preparation for landing should begin midway the flight Torso should remain upright

20 LONG JUMP CONSIDERATIONS Landing Impact and Post impact Characteristics 1. Leg Extension 2. Arm Sweep and movements 3. Absorption of Forces 4. Post Absorption

31 TRIPLE JUMP

32 TRIPLE JUMP CONSIDERATIONS Sprint Mechanics Visual Focus during the approach Checkmark System

33 TRIPLE JUMP TAKEOFF The Athlete should not make a radical mechanical change on the penultimate step Vertical pushing associated with maximal velocity mechanics are especially import in the final steps of the triple jump approach Conservation of Postural Integrity Conservation of maximal desired Velocity Mechanics Takeoff step should be under the athlete s COM Large horizontal displacement of the body Free leg should swing powerfully in a forward and upward direction

34 LEAVING FROM THE BOARD Strong swinging movement of the arms Single arm techniques are preferred because they help the jumper mitigate horizontal velocity loss through the board Double arm actions can be used at takeoff, but not prior to takeoff

35 PHASE CONSIDERATIONS Conservation of postural integrity Stability Pelvic alignment

36 PHASE CONSIDERATIONS Contact should occur slightly in front of the athlete s COM Dorsiflexed ankle Heel to toe, rolling contact with foot Slight give in takeoff leg sets up stretch reflex Takeoff leg should extend continually and completely during takeoff

37 PHASE CONSIDERATIONS Swinging Segment Movements Elastic Energy Amplitude of movement Arm movements Swing leg radii and Pelvic Alignment Blocking

38 PHASE CONSIDERATIONS Free Lig should straighten and fall back underneath the jumper s body Hop Leg should be relaxed and late

39 STEP PHASE Low and Straight swing leg sweep will help control rotation Lifting the knees in the step phase should not be overemphasized The ability to hold or ride the step phase is always determined by pelvic posture

40 JUMP PHASE 1. Excessive forward lean is a common error 2. Good posture should be conserved 3. Hang technique is the most common jump tecnique

41 LANDING Movements of landing are the same as those of the Long Jump
