Strength and conditioning lab notes (need to extract notes from other deck) Flashcards
When lifting does increasing force reduce velocity?
Yes
Describe the evaluation of the sport through the eyes of a sport and conditioning coach?
Movement analysis:
Sport specific movements and range of motion
Muscles involved in the movement
Muscle actions and movement velocities
Physiological analysis:
Metabolic specificity
Strength, hypertrophy, power, muscular endurance
Game duration, work to rest ratio
Common injuries associated with the sport
How is an athlete profile deployed by an strength and conditioning coach?
Training status:
Injuries - current and previous history
Exercise technique skill level
Training background:
Training age
Recent training history
What’s good posture and bad posture?
Good posture is that state of muscular and skeletal balance which protects the supporting structures of the body against injury or progressive deformity
Poor posture is a faulty relationship of the various parts of that produce increased strain on the supporting structures and in which there is less efficient balance of the body over its base of support
Optimal standing posture?
Head - nuetral and absence of tilt and rotation
Cervical spine - slight anterior convex curve
Shoulders - level, no elevation or depression
Scapulae - neutral , Flat on rib cage, medial borders run parallel
Thoracic spine - slight posterior convex curve
Lumbar spine - Slight anterior convex curve
Pelvis, hip joints, knee joints, ankle joints all neutral
Feet parallel or slightly out
Common postural defects?
Forward head travel
Shoulder height discrepancy
Protacted/rounded shoulders
Winged scapulae
Kyphosis
Scoliosis
Lordosis and flat back
Knee valgus and varus
Pigeon toe and duck fee
Potential causes of postural defects?
Injury
Sports and stress related activities, adaptive muscle shortening or lengthening
Limb length discrepancies
Nerve compression or stretching
Can posture adaptation be good?
Yes can enhance performance and prevent injury in sport
What is motor control?
Integration of sensory information (internal and external) and prior experience for the production of a motor response
What is motor learning?
Motor control processes associated with learning and experience resulting in a relatively stable change to the ability to produce skilled movements
What is motor development?
Changes to motor behaviour across time and over an individuals lifetime
Stages of motor learning?
Cognitive (verbal-motor stage):
Gathering information
Large gains, inconsistent performance
Associative (Motor stage):
Putting actions together
Small gains, disjoinnted performance
Autonomous (automatic stage)
Much time and practice
performance seems unconscious and automatic
2 types of coaching?
Internal:
Focus on body movement
External:
Focus on movement effects
External focus is better
Sometimes internal can still be used
Constrained action hypothesis
Individuals who try to consciously control their movements (i.e., adopt an internal attentional focus) tend to constrain their motor system and interfere with automatic control processes. That is, the automatic control mechanisms that have the capacity to control movements effectively and efficiently are disrupted.
In contrast, focusing on the movement’s effect allows for a more automatic mode of control. It promotes the utilization of unconscious, fast, and reflexive control processes, with the result that the desired outcome is achieved almost as a by-product.”
Process of a training camp?
Alarm phase - its new so performance declines
Resistance phase - adapting so performance increases
Super-compensation phase: performance is better than initial this is where we want it to end
exhaustion phase or detraining phase - did too much performance declines
