Warm-up

ExRx.net > Exercise Information > Outline

Types of Warm-ups

  • Passive: increase temperature by external means
  • General: increase temperature using non-specific body movements
  • Specific: increase temperature using similar biomechanics used in subsequent, more strenuous activity.
    • best option since it provides rehearsal of activity or event

Warm-up Benefits

  • Rehearsal of movement
  • Elevation of body temperature
    • increase dissociation of oxygen from hemoglobin an myoglobin
    • lowering of activation energy rates of metabolic chemical reactions
    • increase muscle blood flow
    • reduction in muscle viscosity
    • increase sensitivity of nerve receptors
    • increase speed of nervous impulses
  • Reduces incidence and likelihood of musculoskeletal injuries
  • Supplies adequate blood flow to heart
    • warm up of two minutes prior to sudden exertion can decrease relative myocardial hypoxia and decrease blood pressure during exercise.
    • warm up may precede strenuous exercise by as much as 10 to 15 minutes and still decreased arrhythmias indicative of inadequate oxygen to the heart.
    • warm up may be particularly crucial for those with a degree of underlying coronary artery disease.
      • although the original study examined men ages 21 to 52 years who where asymmptomatic to heart disease

Weight Training Warm-up

  • 12 to 15 reps performed before workout set
    • Approximately 50% of workout weight (10 RM)
    • 30 seconds to 3 minutes rest before workout set
  • Benefits of specific warmup
    • muscles and joint can be warmed up with the exact mechanics which will be performed during the workout set(s)
      • muscle and joint is less susceptible to injury
      • muscle can contract with greater intensity
      • motor skill and breathing can be rehearsed
    • Specific warm up can be considered more effective for weight training than general warmup
      • Example of general warmup: jumping jacks, aerobic warm up, etc.
  • No warm up set is required for high repetition exercises
    • Example: 20-30 or 20-50 reps on abdominal training
    • high repetition sets are not as intense and serves as a warm up in themselves.
  • A second warm up may be performed on heavy movements or if the muscles and joints involved may be more susceptible to injury (based on past experience)
    • Example: squats, deadlift, and possibly bench press
