Q

Joint stability and injury prevention

A
  • Strong muscles help stabilize joints and supports the MSK system
  • Provide better protection and reduce the risk of injuries (strains and sprains)
  • Especially important as people age and are more susceptible to MSK injuries

Q

Metabolic health

A
  • Muscles are metabolically active tissues and an increase in muscle mass can contribute to higher resting metabolic rate
  • This can have positive effects on weight management and overall metabolic health (reduces risk of obesity and T2D)

Q

Functional independence

A
  • Maintaining muscular strength is essential for performing daily activities
  • Lifting groceries, carrying backpack
20
Q

Posture and alignment

A
  • Strong muscles help support proper posture and body alignment
  • Good posture is associated with reduced strain on spine and can alleviate/prevent neck and back pain
21
Q

Cardiovascular health

A
  • RT has been linked to improvements in cardiovascular health
  • some studies suggest it can contribute to lower BP and improved lipid profiles
22
Q

Mental health

A
  • Regular PA (including strength training) has shown to have positive improvements on mental health
  • Exercise can help reduce symptoms of anxiety and depression, improve mood and enhance overall well being
23
Q

Healthy aging

A

Natural loss of muscle mass and strength known as sarcopenia
- maintaining muscular strength can help slow this process allowing individuals to maintain independence and quality of life

24
Q

Chronic disease management

A

RT has been associated with improved outcomes in individuals with chronic diseases like arthritis, heart disease and COPD

25
Power generation
Muscle strength is closely linked to power - weight lifting, sprinting, jumping
26
Enhanced performance
Muscle strength contributes to improved performance in activities that involve lifting, pushing, pulling, carrying - greater advantage as athlete with more MS - ME is key for events that need sustained effort over time (rowing)
27
Neural adaptations to resistance training
1 . Increased synchronization of motor units - more units recruited = greater force production = better overall strength 2. Increased firing frequency to muscle - more coordinated firing = enhanced force production and control 3. Less GTO activity (inhibition) - GTO inhibits over activation, reduced GTO means more muscle force used 4. Less co activation of antagonist muscles - smoother more precise movements, reducing injury risk 5. Improved motor unit synchronization - more efficient and powerful contractions and movements
28
Structural adaptations to resistance training
1. Increased CSA - more contractile proteins (not fiber) = more strength and power 2. Increased tendon-ligament stiffness - attached to muscles = better integrity, joint stability and less injury risk 3. BMD - increases and will decline risk of fractures and osteoporosis 4. More muscle capillary density - more mitochondria = more energy supply and efficiency
29
Acute hormonal responses to RT
ALL INCREASE - Catecholamines (EP, NPE, dopamine) - GH - IGF-1 - Cortisol - Testosterone
30
Catecholamines
EP (adrenaline) helps prepare body for PA (increases HR, dilates airways and mobilizes energy stores) to meet increased demands for fuel NPE acts as neurotransmitter and hormone, supports fight/flight (increase alertness, HR, blood flow to muscles) Dopamine is linked to reward, motivation and motor control - overall neurochemical response to exercise
31
Growth Hormone (GH)
Has anabolic effects, stimulating protein synthesis and supporting tissue repair and growth
32
Insulin-like growth factor (IGF-1)
Closely linked to GH and plays role in muscle growth, tissue repair and overall anabolic processes
33
Cortisol
Catabolic hormone involved in breakdown of tissues and mobilization of energy - its increase during RT is part of body's stress response
34
Testosterone
Anabolic hormone that promotes muscle protein synthesis, contributing to muscle growth and repair
35
Hormonal responses to RT
Greatest acute hormonal elevations with moderate-high intensity, using short rest intervals and stressing large muscle mass - low volume, high intensity, long rest not as beneficial
36
Periodization
Systematic and planned approach to organizing and structuring training programs over specific period - vary intensity, volume and type of exercise to prevent burnout and promote long term improvement - macro-, meso-, and microcycles
37
Goals of periodization
- To create training plan that will transfer to real-life goal - Improve adaptation of body to demands being placed upon it - Help to peak when necessary for competition/event
38
Benefits of periodization
- structured progression (broken into manageable chunks) - prevention of plateaus (introduce variety in exercises, intensity and volume) - avoid overtraining (planned recovery to prevent injury and burnout) - holistic approach (strength, cardio, flexibility, mobility) - adapt to individual needs - sustainable lifestyle changes (supports development of long-term lifestyle changes) - injury prevention - improved mental well being (better motivation, less stress) - enhanced motivation and accountability - versatility and adaptability
39
Seyle's General Adaptation Syndrome
three-stage process describes our body's reaction to stress: alarm, resistance, exhaustion
40
Macrocycle
Addresses overall annual/seasonal training goals. It's the big picture that outlines general progression, major events and areas of focus - usually 6 months to 1 year (or more) - based on individual needs, responses to training, long term goals
41
Mesocycle
More detailed planning and focus on specific aspects of training. Each will have their own distinct goal ex: strength, power development, skill - usually 2-6 weeks (multiple per macrocyle) - short term goal to reach the long term goal
42
Microcycle
Breaks down training plan into short term phases, and details daily/weekly training sessions. Allows for adjustments and immediate feedback - focus on specific FITT variables to meet goals of mesocycle - include rest/recovery/adaptation weeks - usually few days up to 2 weeks
43
Linear periodization
- Start with low reps (intensity) and high volume - As approaching competition, should switch to high volume and lower intensity - hypothetically best for beginners - May be limited to diverse training or multiple peaks in the season
44
Undulating periodization
(aka Non-linear periodization) Training approach involving frequent changes in intensity and volume within short time frames such as micro and mesocycles - prevent boredom, address multiple goals, prevent plateaus - requires frequent monitoring and adjusting, possible to overtrain
45
Block periodization
Spend few weeks on particular aspect of fitness - more concentration and specialized improvement - shorter, more intense than linear periodization - good for advanced athletes, can allow numerous peaks - can be complex and fatiguing
