Mastering the Drive Phase & Acceleration
Lesson 1: Starting Mechanics
The Reaction Challenge
The Ball Drop Drill
Partner 1 holds a tennis ball at shoulder height.
Partner 2 stands in a ready position, hands over the ball.
Partner 1 drops the ball without warning.
Partner 2 must catch it before the second bounce!
"How fast can your brain tell your muscles to move?"
3 Keys to a Powerful Start
01
Low Center
Stay low! Your body should be a coiled spring ready to release energy forward, not upward.
02
Triple Extension
Push through your ankle, knee, and hip simultaneously for maximum ground force.
03
Arm Drive
Aggressive "pocket to chin" arm swings balance the force generated by your legs.
The Drive Phase
The first 10-15 meters
Form Check
1 Head Down: Keep your eyes looking 2-3 feet in front of your start line.
2 Positive Shin Angle: Shins should point forward, not vertical.
3 Piston Action: Drive the knees forward with power.
Don't stand up too early!
Track Mission: The 3-Step Drive
The Drill
Line up in a "Falling Start" position (lean forward until you have to step).
Explode for exactly 3 steps focusing ONLY on the drive angle.
Freeze on the 4th step to check your body height.
Repeat 5 times with partner feedback.
Pro Tip
Imagine you are pushing a heavy sled. Your body should be at a 45-degree angle to the ground during those first few steps.

Lesson 1: Starting Mechanics & Drive Phase
Teacher Resource
Grade 7 • PE • Track & Field
Instructional Focus
The goal of this lesson is to move students from a "standing and running" mindset to a "pushing and driving" mindset. In 7th grade, many students pop straight up during the start. This lesson emphasizes horizontal power and staying low to overcome inertia.
Materials Needed
Tennis balls (1 per pair)
Track or flat 40m space
Cones (start/stop markers)
Whistle
Lesson Timeline
0-10m
The Hook: Reaction Ball Drop
Engage neuromuscular systems. Challenge students: "Your body is a machine. How fast is the signal from eyes to legs?"
Check for: Soft knees, balls of feet, focus on the partner's hand.
10-25m
Direct Instruction: The Drive Mechanics
Model the "Falling Start." Demonstrate the difference between popping up (slow) and pushing away (fast). Highlight the 45-degree angle.
Key Cues: "Big arms," "Push the ground away," "Eyes on the ground."
25-45m
Practice: 3-Step & 10m Sprints
Students perform the 3-step freeze drill. Progression: move to 10m explosive starts. Pairs give feedback using the "Low-Push-Swing" checklist.
45-50m
Debrief & Exit Ticket
Gather in a circle. Ask: "Where should your eyes be in the first 5 meters? Why?"
Troubleshooting Common Mistakes
Mistake: The "Pop Up"
Student stands upright immediately, losing horizontal momentum.
Fix: Have them run under a low horizontal line (visualize a garage door) for 5 meters.
Mistake: Small Arms
Tiny, fast arm movements that don't match leg power.
Fix: Cue "Pocket to Chin" or "Hammer the nail" backwards with the elbows.

Spot the Difference
Compare an Olympic sprinter to a beginner runner in slow motion. Look for:
Knee Height at peak stride
Where the foot hits the ground
Relaxation in the shoulders/face
[Slow Motion Comparison]
The Max Velocity Checklist
Tall Posture
"Run tall." Imagine a string pulling your head toward the sky. Hips should be high, not sitting back.
Relaxed Tension
"Hands like you're holding an egg." Tension in the face and shoulders slows you down. Stay smooth.
The Science of Drills
A-Skips & B-Skips
A-Skip: High Knee
Focuses on Knee Drive and Dorsiflexion (toes up!).
"The higher the knee, the more space you have to generate downward force."
B-Skip: Clawing
Focuses on the Foot Strike . Pull the foot back under your center of mass.
"Don't reach forward! Reach down and back to grab the track."

Grade 7 • PE • Track & Field
The Mechanics of Maintenance
Once acceleration ends, sprinting becomes a game of "maintenance and relaxation." Students often tighten up as they get tired, which causes deceleration. This lesson teaches them to use skeletal alignment and efficient foot strikes to stay fast without wasting energy.

The "Form Fix" Drills
A-Skips (Drive)
Goal: Isolate knee drive and dorsiflexion.
Cues: "Step over the opposite knee," "Toes to shins," "Rhythmic bounce."
Look for: Soft landings on the balls of the feet. No flat-footed slaps.
B-Skips (Claw)
Goal: Active foot strike under center of mass.
Cues: "Extend and paw," "Pull the track backward," "Cycling motion."
Look for: Active "clawing" sound on the track surface.
Class Flow & Transition
1
Warm Up (8 min)
Dynamic stretching followed by 4x20m builds. Each build gets progressively faster but stays relaxed.
2
Skill Block (15 min)
Teach A-Skips and B-Skips. Walk through slowly, then add rhythm. Students should perform 2x15m of each.
3
Fly-Ins (20 min)
Mark a 50m zone. 0-20m: Acceleration. 20-40m: Max Velocity (The Zone). 40-50m: Deceleration. Only grade the middle 20m.
Quick Diagnostic Key
Head bobbing = Weak core / Lack of focus
Reaching forward = Braking effect (slows runner)
Fists clenched = Shoulder tension (energy waste)
Looking back = Disrupts mechanics/safety hazard

Infinite Baton Challenge
The Mission
Keep the baton moving for 5 minutes straight as a whole class or group.
No dropping the baton.
No stopping.
Everyone must touch it.
"The baton is the brain of the race. Don't let it go to sleep!"
The Blind Exchange
Outgoing
Position: Inside of lane, looking back at mark.Action: Explode when incoming runner hits the mark.Hand: "High-V" or "Hand-Back" on verbal command.NEVER look back once you start!
Incoming
Position: Outside of lane to avoid collision.Command: Loud "STICK!" or "GO!" when 2m away.Action: Reach forward, place baton firmly in hand.Maintain speed through the zone!
The 30-Meter Zone
ACCEL
Exchange Zone (30m)
The Mark
The spot on the track where the outgoing runner starts moving.
The Stick
The verbal command given by the incoming runner.
The Pass
Ideally happens in the middle of the zone at full speed.
Avoid the DQ!
Out of Zone
Baton must change hands entirely within the 30m exchange zone.
The Drop
If you drop it, the person who dropped it must pick it up without interfering.
Interference
Stay in your lane after the pass until the track is clear.
Pro Tip
Trust your teammate. If you look back, you slow down!

Lesson 3: Blind Exchanges & Team Timing
Teacher Resource
Grade 7 • PE • Track & Field
The Baton is Brain
The 4x100m relay is often won by the team with the best handoffs, not the fastest runners. At the 7th grade level, the primary challenge is trust . Students naturally want to look back. This lesson focuses on the verbal command and the spatial timing of the 30m zone.
Setup Checklist
Batons (1 per 4 students)
Half-cones (for "marks")
Tape or chalk (for zone lines)
Drill Progression
01
Stationary Handoffs
Pairs stand 2m apart. Practice the "Stick!" command and the "Hand-back" (palm up, thumb out). Switch roles every 10 passes.
02
Walking/Jogging Passes
Pairs move at 50% speed. Emphasize "Lane Integrity": Incoming on the outside, Outgoing on the inside. Pass from Right hand to Left hand.
03
The "Mark" Challenge
Full speed in the zone. Outgoing runner places a cone 10-15 steps behind them. When the incoming runner hits that cone, the outgoing runner EXPLODES.
Cues for the Incoming
"Be loud! Yell 'STICK' when you can touch them."
"Run THROUGH the zone. Don't slow down."
"Place it firmly. Don't just slap at them."
Cues for the Outgoing
"Trust the eyes in the back of your head."
"Accelerate like a 100m dash start."
"Big target. Keep the hand still."
Problem: Runners are colliding
Solution: Reinforce Right-to-Left passing. Runner 1 (R hand) → Runner 2 (L hand). This keeps them on opposite sides of the lane.

Lesson 4: Middle Distance Pacing
The Pacing Paradox
Why can't we just sprint?
If you run the first 100m of a 400m race at 100% effort... what happens at the 300m mark?
"The Piano on the Back" effect.
The Challenge
Predict your 400m time.
Sprint the first 100m "All Out".
Record your split times every 100m.
Analyze where the "crash" happened.
Energy Management
Positive Split
Starting very fast and getting progressively slower.
"Fly and Die" — Usually results in a slower overall time and extreme fatigue.
Negative Split
Starting controlled and running the second half faster than the first.
"Finish Strong" — The secret of elite middle-distance runners.
The 400m Strategy Map
0-100m
Explode
Get up to speed. Aggressive drive phase on the curve.
100-200m
Transition
"Float" on the straight. Maintain speed with 90% effort.
200-300m
Re-Engage
Attack the second curve. Knees up, arms driving hard.
300-400m
Dig Deep
Maintain form through the "Burn". Focus on your finish line.
The Split Challenge
Run 2 x 200m Repeats.
Run 1 (Tempo)
Run at 75% effort. Focus on a steady split time.
Run 2 (Strategy)
First 100m at 70%, Second 100m at 100%. Aim for a Negative Split!
"Control your pace, or your pace will control you."

Lesson 4: Energy Management & Splits
Teacher Resource
Grade 7 • PE • Track & Field
Beyond the Sprint
Middle distance (400m/800m) is the bridge between sprinting and endurance. The primary learning outcome is Self-Regulation . 7th graders often lack the kinesthetic awareness to judge their own speed. This lesson uses split times to provide objective data on their internal "governor."
Tools for Success
Stopwatches (1 per pair)
Cones at 100m, 200m, 300m
Split Trackers (Worksheets)
The 400m Coaching Blueprint
Phase 1: The Build (0-100m)
Cue: "Drive out of the blocks." They should reach 95% of top speed quickly but efficiently.
Phase 2: The Float (100-200m)
Cue: "Relax the shoulders." The goal is to maintain the speed generated in Phase 1 with the least amount of effort possible.
Phase 3: The Attack (200-300m)
Cue: "Turn the corner." This is where the race is usually won or lost. Students must consciously increase their effort to combat fatigue.
Phase 4: The Dig (300-400m)
Cue: "Eyes on the finish." Focus on mechanics: high knees and pumping arms to offset "heavy legs."
The Split-Time Experiment
Step 1: The "Fly and Die"
Have half the class run a 400m. Tell them to sprint the first 200m as hard as they can. Partners record splits at 200m and 400m. Expect a massive difference (positive split).
Step 2: The "Calculated Finish"
Tell them to run the first 200m at a "comfortable fast" pace (approx 80%). Then, "Sprint" the final 200m. Compare times. Usually, total time is faster even though they felt slower.
Closing Discussion: "Why did your body feel more 'in control' during the second run? How did that control affect your final time?"

Lesson 5: Performance Assessment
Teacher Resource
Grade 7 • PE • Track & Field
The Performance Model
Assessment should be based on the execution of technique under pressure, rather than just raw speed. A student who finishes last but maintains a perfect drive phase and relaxed shoulders shows more mastery than a naturally fast student with poor mechanics.
Standard Met
Proper Form + Strategic Application
Technique Rubric
Category Level 4: Mastery Level 3: Proficient Level 2: Developing Start & Drive Phase Maintains 45° lean for 10m+; triple extension visible; head down. Leans during first 3-5 steps; full leg extension; reaction time is good. Stands up immediately; arms crossing midline; slow reaction. Max Velocity Form Upright posture; high knees (toes up); complete relaxation in face/hands. Mostly upright; good knee drive; some tension in shoulders. Sitting back in hips; reaching forward (heel strike); very tense. Relay / Pacing Strategy Blind handoff executed at full speed; OR negative split confirmed by split data. Successful pass but slows down; OR even splits recorded. Looked back during pass; OR "flew and died" (heavy positive split).
Official's Logistics
1. Heats & Lanes
Group students by estimated ability to keep races competitive. Assign 1 student per lane for sprints, or 1 team per lane for relays.
2. Timing & Recording
Use "Backup Timers." Have non-running students use phones or stopwatches to catch splits for their peers. Record all data on the master sheet.
Safety First
No one enters the track during a race. Finishers must stay in their lanes until they have decelerated to a walk and the "track clear" call is made.
