Definitions
Warm – up
Activities and movements that increase body temperature
prior to exercise
Stretching
Activities or motions that increase the extensibility of muscles
Purposes
Warm-up
– Improve performance
• Increase body temperature
– Increases muscle force, nerve conduction, rate of chemical reactions,
strength and power
• Increase heart rate and respiratory rate
– Increase blood flow and exchange of O2 and CO2
• Mental/psychological preparation
– Imagery, Focus of attention, Motivation, Arousal
– Decrease injuries
• Increase body temperature
– Improve extensibility of muscles
Purposes
Stretching
– Long term (daily stretching over months and years):
• Improve flexibility
– Attain proper positions or postures for sport
– Improved performance
• Avoid muscle or joint imbalances
– Maintain proper mechanics
– Short term (stretching prior to exercise):
• Improve extensibility of muscles and pain free range of motion
– Prevent muscle strains or other injuries
Effectiveness
Stretching
– Limited and conflicting evidence that stretching PRIOR to
exercise decreases injury rates
• Pre-participation stretching is
– Ineffective in reducing over use injuries (military, running, team
sports)
– Only somewhat effective in reducing muscle strains
– Stretching PRIOR to performance decreases force
production of muscles
• Pre-participation stretching:
– Decreases strength output
– Can decrease power output
Recommendations
Warm-up
– Focus on active (dynamic) components:
• Generally improve performance
• May lessen injury rates
– To enhance performance:
• Raise body temperature (avoid excessive thermoregulatory strain)
• Elevate VO2
• Include brief task-specific bursts
– To prevent acute sport specific injuries:
•
•
•
•
Warm up exercises – about 5 min
Technique alignment exercises – about 5 minutes
Balance exercises – about 5 minutes
Strength & Power exercises – about 2 minutes
Specifics for Skaters – Warm-up
Practice – Off ice
• 5 minutes of activities to raise body temperature
– Jump rope , Exercise bike, Slide board, Jogging
• 5 minutes dynamic stretching
– Ankles, Knee flexors/extensors, Hip flexion/extension, Hip
Abduction/Adduction
• 5 minutes balance/strength/speed /power
– Lunges
– Off ice jumps & Landings
– Sprints or quick bursts with jump rope, bike, slide board
Specifics for Skaters – Warm-up
Practice – On ice
• 5 minutes of skating to raise body temperature
• 5 minutes dynamic stretching
– Next to board
• Knee flexors/extensors, Hip flexion/extension, Hip Abduction/Adduction
– While skating
• Lunges, squats
• 5 minutes balance/speed/power
– Crossovers and glide length of ice on one foot
– Waltz jumps focus on height and landing
– Power stroking, footwork, …
Specifics for Skaters – Warm-up
Competition
• Off ice warm up (about 15 minutes) prior to on ice group warm-up
• Depending on skate order, after group warm-up
– Short wait:
• Skates on:
– Mental run through
– Dynamic stretches to stay warm
– Long wait
• Skates off:
– 5-10 minutes warm up that can be repeated
– Walk through program off ice
• Skates on
– Mental run through
– Dynamic stretches to stay warm
Specifics for Skaters – Warm-up
Things to remember:
– Rinks are cold
– Skaters will cool off quickly
• Have Layers
• Keep Moving
Recommendations
Stretching
– Flexibility is important
– Skaters can easily develop muscle imbalances
A habitual stretching program is important
– Stretch after practices, in evenings
– Raise body temp prior to stretching
– Target muscle groups that:
• Tend to get tight and are over worked
• Allow needed flexibility for sport performance
Specifics for Skaters – Habitual Stretching
Types of Stretches
• Static
– Recommended 5 minutes of total stretch per muscle group
– Typically do 5 x 60 seconds
• PNF Stretching - common technique is Contract-Relax
– Contract muscle against resistance for 10 seconds
– Relax and stretch for 30 + seconds
– Repeat 2 to 5 times
• Dynamic Stretching
– Move joints through ROM with controlled exaggerated motions
– Can do set time or repeat set distances
Specifics for Skaters – Habitual Stretching
Muscles that tend to get tight:
– Calf (gastrocnemius and soleus)
Specifics for Skaters – Habitual Stretching
Muscles that tend to get tight:
– Tibialis Anterior
Specifics for Skaters – Habitual Stretching
Muscles that tend to get tight:
– Low back (erector spinae)
Specifics for Skaters – Habitual Stretching
Muscles that tend to get tight:
– Hip Abductors (TFL, Gluteus
Medius)
Specifics for Skaters – Habitual Stretching
Muscles that tend to get tight:
– Hip Adductors (Iliopsoas, rectus
femoris)
Specifics for Skaters – Habitual Stretching
Muscles that tend to get tight:
– Hip Flexors (Iliopsoas, rectus
femoris)
Specifics for Skaters – Habitual Stretching
Muscles that tend to get tight:
– Hip Extensors (gluteus
maximums, hamstrings)
Specifics for Skaters – Habitual Stretching
Muscles that tend to get tight:
– Hip Lateral Rotators (piriformis,
gluteus maximus)
Stretching Tips
1. After practice, training, or evenings is recommended
2. Warm up muscles before stretching
– If at rink, find a warm room
3. Aim for 5 minutes of each muscle group
– Many stretches will do more than one muscle group at a time
4. Focus on:
– Muscles prone to tightness/imbalances
– Joints needing range of motion
5. Flexibility does not necessarily
• decrease injury rates
• Improve performance
Three Keys to Success
• Warm–up
– Raise your body temp,
HR, breathing rate
• Warm-up
– Use dynamic stretching
to take muscles through
ROM
• Warm-up
– Add balance, speed, and
power activities
And Lastly
• Maintain muscle
balances and joint
ranges of motion with
stretching as part of
your conditioning
program not as part of a
warm-up
