Muscular Terms
• Strength
• Flexion/Extension
• Endurance
• Elevation/Depression
• Power
• Prone/Supine
• Muscular Fitness
• Abduction/Adduction
• Flexibility
• Anterior/Posterior
• Repetition
• Aerobic/Anaerobic
• Set
• Hypertrophy/Atrophy
• 1RM
• Isotonic (same tension): movement of set resistance
throughout ROM (free weights, machines)
– Concentric – muscle shortening
– Eccentric - muscle lengthening
• Isometric (same length): tension without observable
shortening or lengthening; ↑ strength in limited ROM
• Isokinetic (same speed): realistic ROM, dangerous
• Plyometric (jump training): athletes, est. strength/agility
• Actin/Myosin crossbridge animation:

Resistance training: systematic program that progressively
stresses the musculoskeletal system
Somatotypes: overall body shape and body composition
characteristics
Endomorph (fat): short neck & limbs, no muscle definition
Mesomorph (muscle): slim hips/waist, broad shoulders, thick joints
Ectomorph (lean): small bones, long limbs, little body fat
