Study Notes
Ankle Joint Anatomy
- The articulating part of the talus is wedge-shaped, broader anteriorly and narrower posteriorly.
- Dorsiflexion: the anterior part of the talus is held in the mortise, making the joint more stable.
- Plantarflexion: the posterior part of the talus is held in the mortise, resulting in a less stable joint.
- The ankle joint is a hinge joint, allowing movement in only one plane.
- Plantarflexion is enabled by muscles in the posterior leg compartment (gastrocnemius, soleus, plantaris, and posterior tibial).
- Dorsiflexion is facilitated by muscles in the anterior leg compartment (tibialis anterior, extensor hallucis longus, and extensor digitorum longus).
Medial Ligament
- The medial ligament is connected to the medial malleolus (a bony prominence projecting from the medial aspect of the distal tibia).
- It consists of four ligaments that fan out from the malleolus and attach to the talus, calcaneus, and navicular bones.
- Its primary function is to resist over-eversion of the foot.
Lateral Ligament
- The lateral ligament originates from the lateral malleolus (a bony projection from the lateral distal fibula).
- It resists over-inversion of the foot and comprises three distinct ligaments:
- Anterior talofibular
- Posterior talofibular
- Calcaneofibular
Types of Cartilage
-
Articular Cartilage
- Connective tissue covering bone ends, providing a load-bearing, low-friction, and wear-resistant surface for joint movement.
- Creates smooth surfaces for movable (synovial) joints.
- Offers shock absorption and protection.
- Has poor regenerative (healing) capacity.
- Damage can lead to tissue degeneration.
- Primarily subjected to compression forces.
-
Growth Cartilage (physis or growth plate)
- Responsible for height growth.
- Fuses (ossifies) in late adolescence, halting growth.
- Bumps (tubercles) on bones for tendon attachment also have growth plates.
-
Fibrocartilage
- Acts as a shock absorber and provides stability within joints.
Biomechanics
-
Newton's Laws of Motion
- First Law: An object at rest remains at rest, and an object in motion remains in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
- Second Law: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
- Third Law: For every action, there is an equal and opposite reaction.
- Work: Done when a force moves an object through a distance.
- Power: The rate of doing work.
-
Energy: The capacity for doing work.
-
Kinetic Energy: Resulting from motion.
- Kinetic Energy of Translation: ½m∙v2
-
Potential Energy: Resulting from position.
- Potential Energy: m.g.h
- Mechanical Energy: The sum of kinetic and potential energy.
-
Kinetic Energy: Resulting from motion.
Physiology
- The type of energy system used and their interaction depend on:
- Frequency of activity
- Duration of activity
- Intensity of activity
- Fitness level
-
ATP (adenosine triphosphate) is utilized in all three energy systems:
- Phosphagen system (ATP-PCr System)
- Lactic acid system (anaerobic glycolysis)
- Aerobic system (oxidative phosphorylation)
Energy System Contribution for Gymnastics

- Training
- Type of training, Altitude
- Sex
- Supplements / Drugs
- Genetics

- Time (Duration): Number of minutes
- Type (Mode): Running
Training the Anaerobic Lactic System
- Type of training: Sport Specific
