Description
What you’ll learn
-
Explain force in sport and daily movement, including magnitude and direction
-
Define moment (torque) and moment arm, and understand the basic idea as force multiplied by distance
-
Predict how changing distance and joint angle can dramatically change joint loading, even with the same external load
-
Describe why muscles must counter external moments with higher internal forces, and how that can increase internal joint loading beyond the external weight
-
Apply a simple biomechanics lens to common movements like squat, deadlift, landing, running, and throwing to improve performance and reduce injury risk
Sports Biomechanics Simplified is designed to give you clear and practical intuition about how the human body handles load, movement, and stress in sport and everyday activities.
Many people assume that injuries and performance problems are mainly about how much weight is involved. In reality, joints rarely respond to weight alone. They respond to moments, the rotational demands created when forces act at a distance from a joint. This simple idea explains why two people can perform the same movement, with the same load, yet experience very different levels of difficulty, fatigue, or injury risk.
In this course, you will learn the two foundational concepts that govern almost all movement: force and moment (torque). Using simple visuals, real sport examples, and everyday movements, we show why distance and joint angle often matter more than load magnitude itself. You will see how small technique changes can dramatically alter joint loading at the spine, knee, hip, and shoulder.
A key focus of the course is understanding internal loading. When an external load creates a large moment, muscles must generate even larger forces to counter it. Because muscle moment arms are small, this compensation can multiply internal joint forces, sometimes far beyond the external load you see.
This course avoids heavy mathematics and expensive laboratory concepts. Instead, it builds biomechanical intuition you can apply immediately. By the end, you will be able to analyze movement more confidently, reduce unnecessary joint stress, and make smarter decisions about training, technique, and performance.
This is biomechanics you can use starting right now.
Who this course is for:
- Coaches and strength and conditioning practitioners who want a simple way to analyze technique and joint loading
- Athletes and gym-goers who want safer training and better performance using clear biomechanics
- Physio, rehab, sports science, PE, and biomechanics students who want the fundamentals without heavy math
- Clinicians and movement professionals who want a clean framework to explain loading, posture, and technique to clients
