Transcript Benefits of Resistance Training

RESISTANCE
TRAINING (RT)
PSE4UI
What is it?
• Resistance training can also be called strength
training or weight training.
• It’s the use of resistance to muscular contraction
to build the strength, anaerobic endurance and
size of skeletal muscles.
• Based on the principle that muscles of the body
will work to overcome a resistance force when
required to do so!
Why do it?
• As the body gets introduced to these types of
exercise stresses, it adapts in a variety of ways.
** The body usually adapts to these stresses in
positive ways, but it will always depend on type,
technique, and style of exposure to resistance
training.
• When you do resistance training repeatedly and
consistently in appropriate ways, your body
becomes more efficient in multiple aspects…

Resistance Training
Advanced Exercise Prescription
Periodization
Training for Power
Training for Strength
Training for Hypertrophy
Exercise Prescription for Weight Loss
Speed & Agility Training
Youth and Resistance Training
Benefits & Effects (p. 66)
• Increased muscularity or hypertrophy
• Size & efficiency of fast- and slow-twitch fibres
• Body composition with fat-free weight gain
• Increase in resting metabolic rate
• Increased efficiency with motor unit recruitment
• Neural unit efficiency & coordination
• Strength, power, endurance throughout entire joint
• Increased strength of connective and support tissues
• Bone density, ligament & tendon strength, joint
stability
Benefits & Effects (p. 66)
• Increased fuel storage capacity of muscle fibers
• Muscles become more efficient at storing ATP &
glucose storage
• Increases in anaerobic threshold
• Increased blood supply to muscles
• O2 delivery & CO2 removal meaning more efficient CV!
• Specific adaptations to exercised muscles
• Improvement to local joints, power, speed, &
endurance
What does this mean
for youth?
2009 Position Statement from National Strength and
Conditioning Association in the Journal of Strength
and Conditioning Research
• Relatively safe for youth.
• Enhances the muscular strength & power of
youth.
• Improves the cardiovascular risk profile of youth.
• Improves motor skill performance & may
contribute to enhanced sports performance of
youth.
2009 Position Statement from National Strength and
Conditioning Association in the Journal of Strength
and Conditioning Research
• Increases a young athlete’s resistance to sportsrelated injuries!
• Can help improve the psychosocial well-being of
youth.
• Can help promote and develop exercise habits
during childhood and adolescence.
A Few Training
Principles/Goals
• Principle of Overload
• Body must be subjected to greater stresses than accustomed to
see physiological change
• FITT
• Frequency, Intensity, Type, Time
• Importance of Technique
• Muscle activation
• Safe stress exposure & avoiding injuries
• Primary Resistance Training Goals
• Strength & Power
• Hypertrophy
• Muscular Endurance
Growth & Development
• Bone formation and growth.
• Weight-baring forces on the body often exhibits
strengthening of:
• Cartilage
• Ligaments
• Tendons.
• Preventative measure against Osteoporosis
• Strengthens bones via remodeling, benefiting in joint
integrity, stability, & injury prevention
Growth & Development
• Hormonal differences
• Testosterone is seen as a natural male steroid hormone
responsible for muscle gain, with males showing higher
increases in its production than females.
• Females tend to show an increase more estrogen, resulting in
body fat deposition, breast development and widening of the
hips.
• Peak Muscle Development: occurs between 16-20 years in
females and 18-25 years in males unless affected by exercise
and/or diet.
More Benefits & Concerns
• Increases in the seemingly obvious:
• strength, power, endurance,
• anatomical & psychosocial parameters,
• improved motor skills & sport performance,
• improved body composition in obese and
overweight children & adolescents,
• improved cardiovascular fitness.
More Benefits & Concerns
• Reduced injury occurrence in sports and recreational
activities
• Forces placed on joints can be much greater in sport
activity when compared to RT.
• Most evidence suggests these injuries occur without
supervision and during very heavy overhead
movements
More Benefits & Concerns
• Most concern with RT and youth is injury to the
epiphyseal plate
• An epiphyseal plate fracture has not occurred when
adhering to established guidelines
• When RT is taught properly the risk of injury of an
epiphyseal fracture is minimal
