Types of Synovial Joints

Study Notes

Synovial Joints

Hinge Joints: allow movement in one plane, e.g. elbow joint
Ball and Socket Joints: offer a wide range of motion in multiple directions, e.g. shoulder joint
Pivot Joints: allow rotation around a single axis, e.g. neck joint (atlantoaxial joint)
Condyloid Joints: permit movement in two planes, but not rotation, e.g. wrist joint
Saddle Joints: enable movement in two planes with greater freedom than condyloid joints, e.g. thumb joint (first carpometacarpal joint)
Gliding Joints: facilitate sliding or gliding movements between bones, e.g. carpals of the wrist

Body Planes

Sagittal Plane: divides the body into right and left
Frontal/Coronal Plane: divides the body into anterior and posterior (front and back)

Tendons, Ligaments, and Cartilage

Tendons: connect muscles to bones, transmitting muscle force to produce movement
Ligaments: connect bones to other bones, providing stability and preventing excessive movement in joints
Cartilage: acts as a cushion between bones, reducing friction and absorbing shock, while also providing structural support and aiding in joint movement

Blood Vessels

Arteries: large, thick-walled blood vessels that carry blood away from the heart
Veins: thinner than arteries, carrying blood back towards the heart
Capillaries: tiny blood vessels where gas exchange occurs between cells and the cardiovascular system

Types of Bones

Irregular Bones: irregularly shaped bones that don't fit into other categories
Flat Bones: strong, flat plates of bone that typically provide protection
Long Bones: longer than they are wide
Short Bones: roughly the same width and length
Sesamoid Bones: bones that sit fixed within a tendon

Heart Rate, Stroke Volume, and Cardiac Output

Heart rate x stroke volume = cardiac output, showing how heartbeats and blood pumped per beat affect total blood flow

Legal Performance Enhancements

Methods include proper nutrition, hydration, adequate rest, strength training, altitude training, and specialized equipment, all within the rules and regulations of sports organizations

Principles of Training Programs

Specificity: training tailored to match the demands of the sport or activity
Frequency: how often you train per week
Intensity: level of effort during exercise
Time: duration of each training session
Type: specific exercises or activities included
Progression: gradually increasing training difficulty
Individuality: recognizing unique responses to training
Diminishing Returns: rate of improvement slows over time
Variety: incorporating diverse exercises
Maintenance: sustaining fitness gains
Overtraining: excessive training leading to harm
Detraining: loss of gains when training stops

Acute Responses and Chronic Adaptations to Training

Acute Responses

Increased Heart Rate (Cardiovascular)
Elevated Respiration Rate (Respiratory)
Muscle Fatigue (Muscular)
Increased Blood Flow to Muscles (Cardiovascular)

Chronic Adaptations

Muscular Hypertrophy (Muscular)
Improved Cardiovascular Endurance (Cardiovascular)
Increased Lung Capacity (Respiratory)
Enhanced Recovery (Muscular/Cardiovascular)
