Chapter 6: Muscular Fitness
health benefits of resistance training
- Increase lean muscle mass - Decrease body fat - Fortify bone - Lower blood pressure - Improve blood lipids - Enhance body's ability to use glucose - Reduce risk of Diabetes, Heart disease and Osteoporosis - Independent physical functioning - Higher quality of life
men (sex differences)
-anabolic hormonal environment -testosterone -greater number of muscle fibers
muscular fitness and aging
-independent living -activities of daily living (improves balance and restore mobility, makes lifting easier, decrease risk for injury and fall, stresses bone and decreases risk of osteoporosis)
women (sex differenes)
-more estrogen and less progesterone, less testosterone -less strength and muscular gains than men
muscular endurance assesment
-push up test for adults -curl up or push up test for youth -chair stand test for older adults
guidlines for safe and effecticve resistance
-start with lighter weights -use proper techniques to reduce risk of injury -allow time to recover -lift in slow, controlled manner -include all body parts and balance strength of antagonistic muscle groups -customize program to fit your needs -no safe shortcuts to strength or muscle fitness
resistance training
An activity that places an additional force against the muscle or muscle group
muscular endurance training FIT
F: 2 days a week I:<50% of 1RM T: 1-2 sets of 15-20 reps
general muscle fitness training FIT
F: 2 days weekly I: 40-60% 1RM T: 1 set of 8-12 reps
muscular endurance training FIT target zone
F: 2-3 days weekly I: 50% of 1RM T: 2-4 sets of 15-20 reps
general muscle fitness training FIT target zone
F: 2-3 days weekly I: 60-80% 1RM T: 1-3 sets of 8-12 reps
Push up test
Measures muscular endurance of the upper body , primarily the pushing muscles
Basic Eight for Calisthenics
Push Ups, Modified Pull Ups, Dips, Crunch, Trunk Lift, Side Leg Raises, Step Ups, Lunge Walk
muscular strength
ability to exert maximal force in a single effort
muscular power
ability to exhibit maximum effort in very short period of time -strength x speed
free weights
barbells and dumbbells
strength training activites
body weight, free weights, weight machines, elastic tubing, medicine balls, stability balls
musular endurance
capacity of skeletal muscles to continue contracting over long period of time
Jack LaLanne 70th birthday
celebrated it by towing a flotilla of 70 boats for a mile in Long Beach harbor with his hands and feet shackled
frequency
days per week
According to PA guidelines of 2018, you should...
do muscle strengthening activities that involve major muscle groups on 2 or more days of a week
FIT formula
frequency, intensity, time
progressive resistance exercise
gradually and systematically increase overload of skeletal muscles
Circuit Exercises for a Fitness Center
hips and legs, quadriceps, hamstrings, chest, back, shoulders, biceps, triceps, low back, abdominal muscles
hypertrophy
increase in muscle size
eccentric
lengthening of muscle
weight machines
mechanical devices that move weights up and down using a system of cables and pulleys
dynamic training
muscle contractions with movement, full range of motion, improvements measured easily by amount lifted
leverage
muscle produces movement due to the fact that it crosses a joint
components of muscular fitness
muscular strength, muscular endurance, and power
progressive overload (principle of resistance training)
must exercise at a level beyond the point to which your muscles are accustomed -increase repetitions (8-12), sets(2-4), and resistance
arm curl test
number of curls in 30 seconds -men curl 8lbs -women curl 5 lbs
time
number of reps and sets
chair stand test for older adults
number of times over 30 seconds1
muscular strength assesment
one repetition maximum (1RM)
muscles work in..
pairs
intensity
percentage of 1 repetition maximum
Agonist muscle movement
prime mover
principle of resistance training
progressive over load, regularity, specificity
concentric
shortening of muscle
type
specific mode
isometric training
strength gains are specific to angle of muscle contraction
repetiotion
the action of repeating something that has already been said or written.
Why measure muscular fitness?
to educate, motivate, form a foundation for exercise prescription, monitor changes
why should we measure muscular fitness
to educate, motivate, form foundation for exercise prescription and monitor changes
mode of training
two types of training methods to improve strength -isometric (static) -dynamic (isotonic)
atrophy
weakening skeletal muscle
antagonist muscle movement
works in opposition to produce opposite movement
developing resistance training program
• Setting goals • Type of program • Choice of equipment • Muscle groups • Order of exercises - large groups first • Number of sets, reps per set
workout components
• Warm-up - 5 to 10 min low-mod intensity aerobic exercise • Muscle conditioning phase -exercise choice, exercise order, number of sets, repetitions, velocity and rest period between sets • Cool-down
