What this sub-topic is asking

NESA wants you to apply the principles of training (specificity, progressive overload, FITT, reversibility, individuality, variation) to each of the four physical capacities (strength, power, speed, flexibility), describe the established methods used for each, and integrate them into a periodised plan for an athlete in a chosen sport (typically a team sport).

The answer

Strength training

Strength is the maximal force a muscle (or muscle group) can produce. The dominant method is resistance training, with loading patterns differing by goal:

  • Maximal strength: roughly 1-5 reps per set at 85 to 100% of one-rep max (1RM), longer rest (3-5 min), lower total volume. Trains neural recruitment and high-threshold motor units.
  • Hypertrophy (muscle size): roughly 6-12 reps at 65-80% 1RM, moderate rest (1-2 min), higher total volume. Drives muscle fibre cross-sectional area increase.
  • Muscular endurance: 15+ reps at lower loads, short rest.

These ranges are widely taught in sport-science consensus documents (ACSM, NSCA). Progressive overload is applied by increasing load, reps, sets, or reducing rest over time. Specificity means choosing exercises whose movement pattern resembles the sport (e.g. squat and trap-bar deadlift for athletes who jump and sprint).

The single chart most worth memorising is the rep-load continuum: as the load falls and the reps rise, the dominant adaptation shifts from neural strength, through hypertrophy, to muscular endurance.

The rep-load continuum: heavy loads at low reps build maximal strength, moderate loads at moderate reps build hypertrophy, and light loads at high reps build muscular endurance A horizontal continuum split into three coloured zones. The strength zone covers about 1 to 5 reps at 85 to 100 percent of one-rep max with 3 to 5 minutes rest and a neural adaptation. The hypertrophy zone covers about 6 to 12 reps at 65 to 80 percent 1RM with 1 to 2 minutes rest and a muscle cross-sectional-area adaptation. The muscular-endurance zone covers about 15 or more reps below 65 percent 1RM with short rest and a fatigue-resistance adaptation. An arrow beneath shows load decreasing and reps increasing from left to right. Values are an illustrative training-science consensus. The rep-load continuum illustrative ACSM/NSCA-style consensus ranges STRENGTH 1 - 5 reps 85 - 100% 1RM rest 3 - 5 min neural recruitment HYPERTROPHY 6 - 12 reps 65 - 80% 1RM rest 1 - 2 min muscle size cross-section ENDURANCE 15+ reps < 65% 1RM short rest fatigue resistance load DECREASES →  reps INCREASE → Power sits OFF this continuum Power is not a rep-load zone but a VELOCITY method: a sub-maximal load (about 30 - 60% 1RM) moved at MAXIMAL velocity, low reps (3 - 5), full recovery - see the next figure.

Power training

Power is the rate of force production (work per unit time). It bridges strength and speed.

  • Plyometrics (depth jumps, bounds, hops, medicine-ball throws) train the stretch-shortening cycle and rapid force production.
  • Olympic lift derivatives (power clean, hang clean, snatch pull, push press) train triple-extension at high velocity.
  • Ballistic resistance (jump squats, bench throws) emphasises moving moderate loads as fast as possible.

Typical loading is lower reps (3-5) with full recovery so quality stays high. Volume must be controlled because plyometric ground-reaction forces are large.

The reason power needs its own method is the force-velocity relationship: force and velocity trade off, and power (their product) peaks at an intermediate load. Strength training lives at the high-force end, speed at the high-velocity end, and power in between, which is why it is trained with sub-maximal loads moved as fast as possible.

The force-velocity curve and the power curve: force and velocity trade off, so muscular power peaks at an intermediate load between the strength end and the speed end A graph with relative force on the vertical axis and movement velocity on the horizontal axis. A descending blue force-velocity curve shows that high force occurs at low velocity (the strength end, on the left) and low force occurs at high velocity (the speed end, on the right). An overlaid orange power curve, equal to force multiplied by velocity, rises then falls, peaking in the middle where both force and velocity are moderate - this is the power zone where ballistic training with sub-maximal loads moved fast is most effective. Labels mark strength training at the high-force end, power training at the peak of the power curve, and speed training at the high-velocity end. Values are illustrative. Force-velocity and power curves illustrative - power = force x velocity peaks mid-range relative force movement velocity → force-velocity power = F x v STRENGTH (heavy, slow) POWER (sub-max, fast) SPEED (light, fastest) low v high v Train power with sub-maximal loads moved at MAXIMAL velocity.

Speed training

Speed is movement velocity, usually trained as sprint speed and change-of-direction speed.

  • Sprint mechanics work: acceleration drills, wall drills, A and B skips. Reinforces posture, knee drive, ground contact.
  • Maximal-velocity sprints: typically 20-60 m efforts with full rest (often 2-3 min for short sprints, longer for longer efforts) so the athlete reproduces near-maximal speed each rep.
  • Resisted sprints: sled drags or sled pushes with moderate loads to bias the acceleration phase; heavier sleds train horizontal force production.
  • Hill sprints: uphill bias the push-off; downhill (used carefully) can train overspeed mechanics.

Specificity matters: a rugby winger needs different distances and recoveries from a soccer midfielder.

Flexibility training

Flexibility is the range of motion at a joint. Three main methods:

  • Static stretching: the stretch is held at end-range, typically 20-30 seconds, multiple repetitions. Best used post-session or in dedicated mobility blocks. Long static stretches immediately before a high-power session can transiently reduce force output.
  • Dynamic stretching: controlled movement through range (leg swings, walking lunges with rotation, A-skips). Best used in warm-up before training and competition.
  • Proprioceptive Neuromuscular Facilitation (PNF): contract-relax patterns, often partner-assisted. Highly effective for range gains; more time-intensive.

Periodising the capacities for a team-sport athlete

A team-sport athlete (e.g. a rugby union player, a netballer, a hockey midfielder) needs all four capacities simultaneously plus aerobic and anaerobic conditioning. Periodisation structures the year into phases so capacities are emphasised without all maxing out at once.

A simplified annual structure:

  • Off-season (general preparation): higher volume hypertrophy and base strength; aerobic base; mobility work; reintroduce sprint mechanics at sub-maximal speeds.
  • Pre-season (specific preparation): shift toward maximal strength and power (Olympic-lift derivatives, plyometrics); speed work at higher intensities; sport-specific conditioning.
  • In-season (competition): maintain strength and power with reduced volume; prioritise speed and recovery; technical and tactical training dominate.
  • Post-season (transition): active recovery, reduced training stress, address injuries, light mobility.

Within a microcycle, heavy strength and high-quality speed work go on separate days from high-volume conditioning to protect quality. This is block or conjugate periodisation in different traditions.

Examples in context

Example 1. The Australian Institute of Sport (AIS) strength-and-conditioning model. The AIS publishes athlete-development frameworks that integrate strength, power, speed and mobility around the competition calendar of each sport. The model emphasises sport-specific testing, individualised loading (since 1RMs vary widely between athletes), and a clear weekly structure that separates high-quality power and speed sessions from heavy conditioning. The AIS is a strong example to cite for sport-science consensus applied in an Australian context.

Example 2. Plyometric training for jump performance. A well-replicated finding in sport-science research is that structured plyometric programs (depth jumps, box jumps, bounds), typically performed two to three sessions per week for several weeks, produce measurable improvements in vertical jump height and sprint acceleration in trained team-sport athletes. The mechanism is improved use of the stretch-shortening cycle and faster rate of force development. The example illustrates progressive overload (jump height, contact intensity, total foot contacts) and specificity (jumping trains jumping) operating together.

foundation3 marksIdentify the rep range, intensity and rest period typically used to train maximal strength, and name the main adaptation it targets.
Show worked solution →
  • Reps: roughly 1 to 5 per set.
  • Intensity: 85 to 100 percent of 1RM (very heavy).
  • Rest: 3 to 5 minutes between sets (so the nervous system recovers fully).
  • Main adaptation: neural - improved recruitment of high-threshold motor units, rate coding and synchronisation (especially in the first 4 to 6 weeks).

Marking criteria: 1 mark for the correct rep/intensity pairing (low reps at high load), 1 mark for the long rest period, 1 mark for naming the neural adaptation. Stating "6 to 12 reps" describes hypertrophy and scores nothing for the rep mark.

foundation4 marksDistinguish between static, dynamic and PNF stretching, and recommend when each is best placed in a training session.
Show worked solution →
  • Static stretching: the stretch is held at end-range (about 20 to 30 seconds). Best placed post-session or in a dedicated mobility block; avoid long holds immediately before maximal-effort work because they transiently reduce force.
  • Dynamic stretching: controlled movement through range (leg swings, walking lunges, A-skips). Best placed in the warm-up before training and competition.
  • PNF: contract-relax patterns, often partner-assisted, exploiting autogenic inhibition. Highly effective for range gains but time-intensive, so used in dedicated flexibility blocks rather than a quick warm-up.

Marking criteria: 1 mark for each method correctly described with its mechanism/duration (max 3), plus 1 mark for correctly placing dynamic in warm-up and static/PNF post-session or in a mobility block. A list with no placement recommendation caps at 3.

core4 marksExplain why a coach would use plyometrics and Olympic-lift derivatives to train power rather than heavy slow squats alone, referring to the stretch-shortening cycle and movement velocity.
Show worked solution →

Power is the RATE of force production, so the load must be moved fast. A heavy 1RM squat develops maximal force but at low velocity, so on its own it trains the high-force end of the curve, not the high-velocity end.

  • Plyometrics (depth jumps, bounds) train the stretch-shortening cycle: a rapid eccentric stretch immediately followed by a powerful concentric contraction, storing and releasing elastic energy and improving rate of force development.
  • Olympic-lift derivatives (power clean, hang clean, push press) load triple-extension that must be completed at high velocity to complete the lift, so they train force AT speed.

Together they shift the force-velocity curve up and right, which is what improves jumping and sprinting. Heavy slow squats build the strength base that power is then expressed from, so the two are complementary, not interchangeable.

Marking criteria: 1 mark for defining power as the rate of force production, 1 mark for linking plyometrics to the stretch-shortening cycle / rate of force development, 1 mark for linking Olympic derivatives to high-velocity force, 1 mark for the conclusion that velocity-based methods are needed alongside (not instead of) the strength base.

core5 marksA coach tests an athlete's loads at maximal velocity and records this (illustrative) force-velocity data for a jump-squat: at 90 percent 1RM bar speed = 0.30 m/s and power output = 510 W; at 60 percent 1RM speed = 0.75 m/s, power = 900 W; at 40 percent 1RM speed = 1.05 m/s, power = 840 W; at 20 percent 1RM speed = 1.55 m/s, power = 620 W. (a) At roughly what load is power output maximised? (b) Explain why power falls off at both the heavy and the light ends, using the force-velocity relationship.
Show worked solution →

(a) Power output peaks at the 60 percent 1RM load (900 W), the middle of the range, not at the heaviest or lightest load.

(b) Power = force x velocity, and force and velocity trade off against each other (the force-velocity relationship):

  • At the heavy end (90 percent 1RM) force is high but the bar moves slowly (0.30 m/s), so the product force x velocity is modest (510 W).
  • At the light end (20 percent 1RM) velocity is high (1.55 m/s) but the force applied is small, so power is again modest (620 W).
  • Power is maximised in the middle where force and velocity are both reasonably high - here around 60 percent 1RM. This is why ballistic power work uses sub-maximal loads moved at maximal velocity rather than near-maximal loads.

Marking criteria: (a) 1 mark for identifying the 60 percent 1RM / mid-range load as peak power. (b) 1 mark for stating power = force x velocity, 1 mark for explaining the heavy-end fall-off (high force, low velocity), 1 mark for the light-end fall-off (high velocity, low force), 1 mark for concluding power peaks at an intermediate load. Treat the figures as illustrative; the reasoning earns the marks.

core5 marksExplain how the principles of specificity and progressive overload would shape an eight-week speed program for a rugby winger, naming the methods used.
Show worked solution →

Specificity - the stimulus must match the sport's demands. A rugby winger sprints in straight lines and curves over roughly 10 to 40 m, accelerating from a moving start and reaching near-maximal velocity. So the program uses:

  • Acceleration work (10 to 20 m efforts, sled pushes/drags) to train horizontal force in the drive phase.
  • Maximal-velocity sprints (30 to 60 m, full recovery 2 to 3+ minutes) to train top-end speed with quality maintained each rep.
  • Sprint-mechanics drills (wall drills, A and B skips) for posture and ground contact.

Progressive overload - the stimulus increases over the eight weeks: distances and total high-speed metres rise, resisted-sprint sled loads increase, and recoveries shorten only once quality is secure. Overload is applied to the quality (speed) sessions, not by adding fatiguing volume that would degrade sprint quality.

Marking criteria: 1 mark for defining specificity and matching it to the winger's demands, 1 mark for naming sport-specific speed methods, 1 mark for defining progressive overload, 1 mark for showing how the overload is progressed across weeks, 1 mark for protecting speed quality (full recovery / not on a conditioning day).

exam8 marksEvaluate the use of plyometric training for improving power in a team-sport athlete, including how it would be programmed and monitored alongside other training.
Show worked solution →

This is an 8-mark evaluate: make a JUDGEMENT about how effective and worthwhile plyometrics are, supported by mechanism, programming and limitations.

Band 6 PLAN.

  • Thesis: plyometric training is an effective and time-efficient method for developing power in team-sport athletes, PROVIDED it is built on a strength base and programmed with controlled volume and full recovery; used carelessly it raises injury risk without adding benefit.
  • Argument line 1 - effectiveness/mechanism: plyometrics train the stretch-shortening cycle and rate of force development, improving vertical jump and sprint acceleration - the qualities team sports depend on (contesting marks, first-step quickness).
  • Argument line 2 - programming: low reps (about 3 to 5) per set, controlled total foot contacts, full recovery, 2 to 3 sessions per week, progressed by intensity (box height, depth-jump drop) and contacts; placed on quality (non-conditioning) days and after a dynamic warm-up, not after heavy fatigue.
  • Argument line 3 - integration/monitoring: separate from high-volume conditioning to protect quality; monitor with jump tests (countermovement jump), sprint times and load/contact counts; watch for soreness and technique breakdown as overload signals.
  • Limitation/judgement: large ground-reaction forces mean injury risk if volume is excessive or the athlete lacks a strength base, so plyometrics are most worthwhile in pre-season and as maintenance in-season, integrated with strength and speed rather than replacing them.

Model paragraph (effectiveness). Plyometric training is effective for power because it directly trains the stretch-shortening cycle: a rapid eccentric loading (the landing of a depth jump) immediately followed by an explosive concentric drive, which stores elastic energy and sharpens the rate of force development. For a team-sport athlete this transfers to exactly the qualities matches demand - a higher vertical jump for a contested mark and a faster first step off the line - and it does so with little equipment and modest session time. The judgement, though, must be conditional: because ground-reaction forces in depth jumps are large, the benefit only materialises when the athlete already has a strength base and the coach caps total foot contacts with full recovery between sets, otherwise the method adds injury risk and fatigue without improving output. Programmed this way - two to three quality sessions a week in pre-season, monitored with countermovement-jump tests and progressed by intensity rather than sheer volume - plyometrics are a worthwhile and efficient power method, best used to complement, not replace, heavy strength and maximal-velocity speed work.

Marker's note: top-band answers (1) reach an explicit JUDGEMENT (the verb is evaluate, not describe), (2) ground the claim in the mechanism (stretch-shortening cycle / rate of force development), (3) give concrete programming detail (reps, recovery, frequency, progression) and monitoring (jump tests, contact counts), and (4) weigh a limitation (injury risk, need for a strength base) so the judgement is balanced. A bare description of plyometric exercises with no judgement caps in the middle bands.

exam12 marksAnalyse how a periodised annual plan integrates strength, power, speed and flexibility for a named team-sport athlete, and justify the structure using the principles of training.
Show worked solution →

A 12-mark analyse-and-justify: show how the capacities are sequenced and combined across the year (cause linked to effect) and justify each choice with a named principle. Markers reward a sustained, athlete-specific argument, not four separate lists.

Band 6 PLAN.

  • Name the athlete: e.g. a rugby union forward (or netball goal defence, hockey midfielder) - state the demands (repeated high-force collisions, short sprints, change of direction, an in-season spanning many weeks).
  • Thesis: a periodised plan emphasises one or two capacities per phase so each is overloaded without all maxing out at once, preserving quality and managing fatigue across a long competition year.
  • Off-season (general prep): hypertrophy and base strength (6 to 12 reps, 65 to 80 percent 1RM), aerobic base, and mobility (static/PNF) to restore range - justified by progressive overload building a foundation and reversibility (rebuild what the transition phase lost).
  • Pre-season (specific prep): convert the base into maximal strength (1 to 5 reps, 85 percent+ 1RM) and power (plyometrics, Olympic derivatives), with higher-intensity speed - justified by specificity (now training the sport's force-velocity demands) and progressive overload.
  • In-season (competition): maintain strength and power at reduced volume, prioritise speed quality and recovery, dynamic warm-ups before games - justified by reversibility (maintenance prevents detraining) balanced against fatigue and individuality (loads adjusted to each athlete and game load).
  • Transition (post-season): active recovery and light mobility - justified by recovery and avoiding burnout.
  • Integration rule: within each microcycle, heavy strength and high-quality speed/power sit on separate days from high-volume conditioning, and dynamic stretching precedes sessions while static/PNF follows them - justified by protecting quality and the acute stretch-induced strength-loss evidence.
  • Synthesis/judgement: the plan works because it applies specificity, progressive overload, reversibility, individuality and recovery in the right sequence; name the model (linear, block or conjugate) and say why it suits the athlete.

Model paragraph (pre-season). In the pre-season the plan converts the off-season's hypertrophy base into usable on-field qualities: the strength sessions shift to maximal loads (1 to 5 reps above 85 percent 1RM) to drive neural recruitment, while power is layered on through plyometrics and hang cleans that train the stretch-shortening cycle and rate of force development. This sequencing is deliberate and justified by specificity - the forward now rehearses the exact force-velocity demands of scrummaging and short sprints - and by progressive overload, since the load and intensity rise as the base from the previous phase allows. Crucially, the heavy strength and high-velocity speed work are placed on separate days from the high-volume conditioning so that fatigue does not erode the quality of either, and dynamic stretching opens each session while static and PNF work is reserved for afterwards to avoid the transient force loss that long pre-session static holds cause. The result is an athlete arriving in-season strong, powerful and fast, with each capacity overloaded in turn rather than all at once.

Marker's note: a top-band response (1) names a specific athlete and their demands, (2) sequences all four capacities (and conditioning) across the phases with the correct loading detail, (3) sustains a cause-and-effect argument (why this phase produces this adaptation) rather than listing, and (4) JUSTIFIES choices by explicitly naming principles - specificity, progressive overload, reversibility, individuality, recovery - and names the periodisation model. Anchoring loading with real numbers (rep/intensity ranges) and protecting quality via session spacing are marks of precision.
