48 to 72 hours
assessments during phase 2: 2
movement screens
core muscular endurance
ability to develop speed at high velocities an relies on a person’s reactive ability
speed strength
Muscle spindles sense differences in
Rate and magnitude of stretch being imposed on the muscle
Performance training phase will last
At least 4 weeks
best small group combination
people with similar fitness goals
1-3 sets per exercise
6-15 reps
Two or three non consecutive training days / week
Guidelines for youth resistance training: 3
spot training : 2
muscles can be spot trained
fat cannot be spot reduced
2 long-term adaptations to resistance training
increase in muscular strength
increase in muscle size - hypertrophy
upper body plyometric sets counted as
of hand contacts
of throws or catches
Anaerobic training causes shift number of muscle fibers from
Type IIa to type IIx
many people can complete 10 reps with _% of their 1-RM weightload
75%
1-RM = 100lbs
100 x .75 = 10 reps at 75 lbs
free weights require
greater activation of joint stabilizing muscles
repetition range for enhancing muscular endurance is _ reps that fatigue muscle within _ seconds
12- 16 reps
75 - 100 seconds
muscle repair after strength training takes _ during which RMR is elevated
72 hours
example of 12 week training cycle
12 weeks = macrocycle
three mesocycles = 4 weeks each
two microcycles = 2 weeks each
in 10 weeks resistance training can decrease resting BP by:
SBP
DBP
3% SBP
4% DBP
distance from joint axis of rotation to the muscle tendon insertion point
muscle force arm
advantage to machine training: 2
proportionately provides resistance when more can ce lifted and less resistance is positions of lower force production
muscle isolation
_ muscular endurance increases as muscular strength increases
absolute muscular endurance
shorter limbs provide
leverage advantages over longer limbs
combination of strength training and aerobic exercise can improve
insulin sensitivity for patient with type 2 diabetes
if resistance training stops, person will lose their strength in
one-half the rate it was gained
begin with: bi-lateral, fixed level machines
progress to:
unilateral, free moving machines
Most important factor for muscular strength
Progressive resistance
Person attempts to lift as much weight as possible using movements that test speed Strength
Olympic lifting
work to recovery ratio for training circuit for muscular endurance
75 seconds work
15 seconds recovery
A response to resistance training resulting in increase of cross sectional area or size of the muscle
Sarcoplasmic hypertrophy
advanced exercisers should train _ times per week
4-7
client who should NOT use creatine:
creatine can boost muscle strength by:
diabetes
hypertension
decreased kidney function
10%
client with a _ forearm can curl heavier dumbbell than client with a _ forearm
shorter, longer
Power can be defined as
Velocity of force production
training muscle to fatigue, then receiving manual assistance from a trainer in the lifting phase for 3-5 post fatigue reps
assisted training
*people are 40% stronger on the eccentric phase
in regard to training range of 8 -12 reps:
8 reps can be completed with _% maximal resistance
12 reps can be completed with _% maximal resistance
80%
70%
recommended sets for hypertrophy training
3-6 sets per exercise
More power production is produced in _ lifting than in _ lifting
Olympic
Powerlifting
cycles of 2-4 weeks, regular reinforcement making small steps
microcycle
skill related parameters 6
power speed balance coordination agility reactivity
supplements that delay fatigue and can enhance muscle force and power output
- PH buffers in muscle tissue
B-alanine and sodium bi-carbonate
Equipment that requires contraction of stabilizer muscles to maintain proper posture
Exercises:
Cables
Triceps pull down
Lay pull down
Chest crossover
Overhead chops
basic strength training can add _ lbs of muscle in _ months
3 lbs
3 months
intensity for hypertrophy training
70 to 80% of max resistance
2 tools not recomended for lunges
barbells
resistance bands
training intensity for muscular endurance
60-70% of maximal resistance
preadolescent strength training most effective means
for young people to build bone density
frequency for hypertrophy training
split routines
six-day split
rep range for muscular strength
increase weightload by_% when _ reps can be completed
4-6 reps
5%, 7 reps
volume =
sets x reps
tendon insertion further from the joint axis =
longer muscle arm = able to lift heavier
regular strength training decreases 4

reverse order that they accumulated the fat
distance from the joint axis of rotation to the resistance application point
resistance force arm
single linear jumps or hops
only plyometric jump with rest in between
10-15 reps
60-70% max resistance
Avoid holding breath to prevent increase in BP
Training older adults:3
recommended weightloads for muscular strength training
80-90% of 1-RM
Stretching shortening cycle
Eccentric contraction of a muscle followed by an immediate shortening (concentric contraction) of the same muscle
- plyometrics
supplement that has potential to increase strength, speed and recovery and prevent over training
glutamine
workout that pairs opposing muscle groups and movement patterns with little rest time between sets
supersets
intermediate exercisers should train _ times per week
3-4
consistent training protocol WITHIN each microcycle that changes variables at the end of each microcycle
linear periodization
Adaptations to endurance and resistance training shift the number of fibers from
From type IIx to type IIa
