of resistance training in the development of the
health related fitness components
Objectives: To demonstrate confidence, sensitivity,
style, safety, creativity and individuality in planning
and teaching resistance training programmes in a
variety of situations

Resistance Training
The performance of an action that requires the
body’s musculature to exert force in order to equal,
or overcome, an externally applied force
Benefits of
Resistance Training
 Improvements in muscular strength
 Increased muscular endurance
 Increased muscular hypertrophy (fibre
recruitment/diameter)
 Reduced injury potential
 Facilitates calorific expenditure and favourable
changes in body composition
 Promotes postural development
Benefits contd.
 Improves body image/self-perceptions of
appearance
 Facilitates functional fitness and improved quality
of life
 Performance enhancement
Resistance Training
Terminology
 Isotonic contraction: The muscle develops tension
while shortening or lengthening (the joint angle
changes)
 Concentric contraction: The muscle develops tension
while shortening (positive)
 Eccentric contraction: The muscle develops tension
while lengthening (negative)
Terminology contd.
 Isometric contraction: The muscle develops tension
without changing length (joint angle stays the same)
 Isokinetic contraction: Maximal tension is developed
throughout the full range of movement. Speed is also
kept constant throughout the movement. Requires
specialised equipment.
Terminology contd.
 Agonist: The muscle that is working, i.e.
causing the joint movement
 Antagonist:A muscle that acts in
opposition to the action caused by the
agonist
Terminology contd.
 Stabiliser: A muscle that, though not involved in the
action itself, contracts isometrically in order to offer
stability during the performance of the exercise
 Synergist: A muscle that aids another muscle in its
action
Terminology contd.
 Valsalva manoeuvre: The act of holding one’s breath
(closed epiglottis) while performing a lift, causing
increased pressure in the thoracic cavity, which can
lead to a sudden increase in blood pressure and a
blackout
 Intra-abdominal pressure: Increased pressure in the
abdominal cavity, which facilitates spinal stabilization
(abdominal tension)
Terminology contd.
 Repetition (rep): One single lift
 Repetitions (reps): The number of times an exercise
movement is repeated without rest
 Set: A group of repetitions of an exercise, e.g. 3 sets of
8 reps = 3 x 8
 Resistance: The load against which we exert, or the
weight lifted
Terminology cond.
 Muscular failure: The point at which maximal lactate
tolerance occurs and at which the individual is
unable to complete the repetition in perfect form,
e.g. Rep Max
 Isolation exercise: Targets one specific muscle
group as the prime mover
 Compound exercise: Targets more than one muscle
group
Terminology contd
 Sticking point: The point of least biomechanical
assistance, where gravitational effect is greatest and
the application of muscular force is weakest
 Repetition maximum: The max number of reps that
can be completed with a given resistance to the
point of fatigue, e.g. 10 RM
Terminology contd.
 Over-grip: Palms of the hands facing the body in a
natural front grip position
 Under-grip: Palms of the hands facing away from the
body
 Alternate/reverse-grip: One hand in over-grip position,
the other in under-grip
Manual Lifting
Procedures
 Approach as near as
possible to the load
 Relax the knees
 Position the feet to ensure a
sound/stable base of
support
 Lower the hands
 Look down
 Grasp the bar (firmly)
 Test the weight - if
too heavy, summon
a spotter
 Raise the
head/inhale
 Lift through the
legs
 Exhale on exertion
 Keep the load close
to the body
 Do not rush
Session 2 Objectives
 Aim: To introduce students to safety issues and various types of
resistance equipment, and to teaching a range of exercises for
the chest
 Objectives:
 Outline the key safety considerations for (a) handling weights (b)
a lifting area (c) supervision of a weights room
 Identify different types of resistance training equipment and
outline the main characteristics of each type
 Compare and contrast free weights and machine weights and the
advantages/disadvantages of each



Demonstrate effective instructional skills for teaching
resistance training exercises
Demonstrate correct personal technique, posture,
3Bs, stability, alignment, momentum, control, safety
and use of equipment when performing (a)
bench/inclined press, (b) supine/inclined fly
Analyse each of the above lifts in terms of movement
and biomechanical principles

Structure of a
Resistance Session
Warm up: General (CV work) or localised (a number of
reps completed with light weight)
Pre-stretch: Muscle groups to be used in the session
(approx 10 secs)
Main body of session: Commencing with low intensity
(light weight/low reps) and progressing to
moderate/high intensity

Definition of Terms
 Programme: The sequential arrangement of
exercises in documented format, designed to enhance
a specific training effect
 Conditioning: A training programme designed to
systematically exercise all parts of the body and to
provide a broad base of strength on which to build a
higher level of strength
 Strength: The ability to exert maximal force in a onceoff effort e.g. 1 RM
 Endurance: The ability to repetitively exert force over
an extended period of time e.g. 15 RM
 Sticking point: The point of least biomechanical
assistance at which maximal muscle-loading occurs
 Training plateau: The point of diminishing returns at
which no further improvements in strength can be
achieved. Programme manipulation is necessary.
