Strenght & Resistance Training

Strenght & Resistance Training

Strenght & Resistance Training

Equipment/Organizational

equipment - ensure platforms - ensure lifting surfaces are non slip - ensure barbells are evenly loaded, use collars - ensure squat rack, pins in good order - ensure dics are not lying around on platforms or lifting area.
medical - first kit available - ice readily available - emergency withdrawal, evavuation procedures established
athlete - ensure correct footwear - suitable attire - teach correct hand care

Terminology

power training - explosive resistance training/plyometrics
resistance training - overall sciencetifically corrrst term encompassing all the above
strenght training - strenght developement
bodybuilding - hyperthrophy emphasis - non strenght, power dependent
powerlifting - squat, deadlift, bench press -strenght base
weightlifting - competitive sport of lifting barbells - power base
weight training - weight lifting, sport performance, physical appearance

Resistance training program design variables

rest period
volume
training load and repetition
exercise order
training frequency

Resistance training system

split training - working on specific muscle each time.
circuit training - a variety of different moves that are performed without rest.
total body training - total body routine training major muscle each time
drop set - a series of sets of the same exercise
compund sets - involve two different exercise for the same muscle group
supersets - involved tw sequentially performed exercise

Picking the right repetition range

muscular endurance - repetition >13 reps - set 2-3 - to increase strenght endurance
hypertrophy - repetititon 8-12 reps - set 3-6 - to increase muscle mass and improve strenght - weight 70-77% of 1RM
strength - repetition: 6-7 reps - set 2-6 - increase in muscle strengt and size - weight 78-83% of 1RM
power - repetition:<1-5 reps - set 3-5 - to increase muscle strenght and power - weight 85-100% of 1RM

Biomechanical principle of strenght training

to contract target muscle
natural path movement
not haunched
proper body alignment

Pre-Preparatory participation

good understanding
instruction
familiar with exercise
stretching and warm up
objective/goal
pre-screening

Personal safety

Techniques - teach correct mechanically sound body position while lifting - teach correct breathing- teach beginners to 'miss' correctly - use low resistance when new skills are being learned - progress resistance steadily - progress resistance at each individuals own rate
discipline - insist good behaviour - do not allow lifters to train alone - ensure spotters are used correctlywhere required - teach correct spotting techniques - limit attempt for beginner - insist on correct warm up, stretching

Objective safety principles in strenght training

set up a save and effective weightlifting and power training facility
teach effective skills in a progressive stage format
teach athletes to be aware of safety principles
ensure athletes are correctly attired
teach safe spotting techniques
recognize possible at risk situation

Exercise technique fundamentals

Spotter - assists to protect athlete from injury
Handgrips - pronated, supinated, alternated, hook grips

Basic terminologies

atrophy - decrease in muscle mass
hypertrophy - increase volume of muscle
1RM - max weight lifted in one time
delay onset muscle soreness(DOMS) - pain or stiffness after uncommon intensity
isokinetic contraction - tension developed by muscle while shortening at constant speed.
isometric contraction - tension in muscle without changes in lenght
synergist - when it assists indirectly in a movement
antagonist - muscle slow down or stop move
agonist - prime mover
eccentric contraction - tension in the muscle while lengthening
concentric contraction - tension in the muscle while shortening
isotonic contraction - the muscle shorten with varying tension

Periodization in resistance training

anatomical adaptation - the body adapt situation during exercise
hypertrophy - enlargement of muscle fibers
maximal strenght - strenght developement
conversion to power/end/speed - movement/muscle specific

Objective resistance training

optimize performance potential
prevention of injuries

Benefits

improve physical function
improve mobility
prevent injury
decrease body fat
increase bone density
increase muscle mass
