IB SEHS | Sliding Filament Theory and Muscle Contraction | Complete Lesson Pack | B.1 HL

IB SEHS | Sliding Filament Theory and Muscle Contraction | Complete Lesson Pack | B.1 HL

Subject: Physical education

Age range: 16+

Resource type: Lesson (complete)

Last updated

14 June 2026

pptx, 2.48 MB
pptx, 2.48 MB

This fully resourced 9-slide lesson pack covers IB Sports, Exercise and Health Science (SEHS) Option B — B.1: Movement and Sports Injuries, explaining the sliding filament theory and the mechanism of muscle contraction at the molecular level for Higher Level (HL) students.

WHAT’S INCLUDED (9 slides):
• Sarcomere structure — Z-lines, M-line, actin (thin filaments) and myosin (thick filaments)
• The sliding filament mechanism — how actin and myosin interact during contraction
• Cross-bridge cycle — attachment, power stroke, detachment and reset
• Role of ATP, calcium ions and troponin-tropomyosin complex in initiating contraction
• Neuromuscular junction — motor neuron signal to muscle fibre contraction
• Visual diagrams of sarcomere shortening during contraction and relaxation
• Links to muscle fibre types (Type I, IIa, IIb) and energy system use
• Applied context — how sliding filament theory underpins understanding of sports performance and fatigue

PERFECT FOR:
✔ IB SEHS HL students studying Option B
✔ Teaching molecular mechanisms of muscle contraction in depth
✔ Linking theory to sport and exercise performance contexts
✔ International school teachers delivering the IB SEHS HL course
