Review for Exam Two
Chapter Six - Biomechanics of Skeletal Muscle
3. Mechanical Behaviors
Types of Contraction;
Force Production: Force-length (sarcomere and whole muscle), Force-velocity,
Power-velocity, Force-time (EMD);
Muscle Training Modalities - Isokinetic, isotonic, isometric exercises
Chapter Ten - Linear Kinematics
1. Linear Kinematics Quantities (definition, units, direction, applications):
Distance and Displacement, distance formula (compute segment length from given
coordinates)
Speed and Velocity: components, slope/velocity, average/instantaneous
velocity
Finite difference method (equal time interval, end-point constraint): compute
instantaneous velocity and acceleration values
Acceleration: direction and sign
Gait related definitions and applications: gait cycle, stride, step, stride length, stride
frequency, pace
2. Projectile Motion
Constant Acceleration Equations
Concepts: Projectile, Trajectory, Projectile Motion, Trajectory, Gravity and Air-resistance
Calculations: Horizontal and vertical velocity components, projectile height & range
(distance): relative height = 0 and usage of equations of constant acceleration
Vf = Vi + at
(1)
2
(2)
d = Vit + ½ at
(3)
Vf2= Vi2 + 2ad
3. Factors Influencing Projectile Motion
Projectile Angle: optimal angle in theory and practice; Projection Speed
Relative Height; Sports applications: long jump & discus throw (time permitting)
Chapter Eleven - Angular Kinematics
1. Angle Measurement
Definition, Unit of Measurement, Type of Angles and Calculation: absolute angle
(segmental angle) & relative angle (joint angle), Clinical &. Canadian definitions of lower
extremity joints
Useful Trig Functions
sin ± = opp / hyp
cos ± = adj / hyp
tan ± = opp /adj
Note: Bring following items to the test: a calculator
