Exam 1 Flashcards
define intensity
estimated as a percentage of 1 Repetition Maximum (RM)
what is the minimal intensity to increase strength
60-65% of 1 RM
what is the optimal intensity for maximal strength gains
80% 1 RM
define training volume
measure of the total amount of work performed.
Measured in joules
how do you estimate training volume
add together the number of repetitions performed in a time period
calculate the total amount of weight lifted and then calculate the total work performed
which is more important for affecting strength gains: total training volume, training frequency, or number of sets
total training volume
what is the optimal rest period for strength/power programs
several minutes between sets
what is the optimal rest period for high intensity/volume
less than one minute
what is the optimal rest period for aerobic power programs
less than 30 seconds
what does training at a fast velocity against light resistance and training at a slower velocity against heavy resistant result in?
velocity specific strength gains
define muscle action with regards to specificity
gains in strength are specific to the type of muscle action used in training (isometric, variable resistance, isokinetic)
define testing with regards to specificity
gains in strength are greater when a muscle is tested the same way it is trained
define muscle group training with regards specificity
each muscle group requiring strength gains or other adaptations to the training program must be trained
define energy source with regards to specificity
physical training may bring about adaptations of the metabolic systems predominantly used to supply the energy needed by muscles to perform a given physical activity
define progressive overload
practice of continually increasing the stress placed on the body as force, power, or endurance capabilities increase due to training
define progressive resistance
stress of resistance training is gradually increased as fitness gains are achieved with training
what is the chance of injury during resistance training
very slim
what are the common injuries of resistance training
muscle sprains and strains
who experiences the most accidental injury during resistance training
children
3 functions of spotters
- to assist the trainee with completion of a rep if needed
- to critique the trainees exercise technique
- to summon help if an accident does occur
purpose of training belts
helps to raise the intra-abdominal pressure, which supports the lumbar vertebrae from the anterior
for isometric training:
- maximal vs submaximal actions?
- # of muscle actions and duration
- effect on muscular hypertrophy
- effecont on joint angle specificity
- effect on motor performance
- use maximal actions for isometric
- 15 reps 3-5 seconds; 3x/week
- can result in hypertrophy but not as well as regular lifting
- very specific for joint angle
- some effect on motor performance
what athletes benefit from isometric training?
rock climbers
define Dynamic Constant external resistance training
(isointernal)
resistance lifted is held constant
describes exercises using free weights and weight training machines
