How to Measure PHVHow to Measure PHV

• Tools and equipment for measuring• If stature data is going to be heavily incorporated into training

plans, data must be very accurate, and thus, the more expensive the purchased equipment should be.

• Ideal equipment:• A free standing or wall mounted stadiometer• This stadiometer would need to have sliding headboards and a dial

or digital (or digital read outs), which would aid in the ease of use• Acceptable equipment includes:• An anthropometer or retractable steel measuring tape• A headboard• A platform for measuring, about 1 m2 made out of standard ply

wood, ideally with adjustable feet

Unacceptable equipment includes:

• A cloth measuring tape• Flexible material• Carpeted floor• An uneven floor• No backboard

Example 1 – Two measurements within 0.4 cm of each other

Stature measurement #1 166.2 cmStature measurement #2 166.3 cm

The above two measurements are within the acceptable range and the mean measurement recorded as 166.3 cm.

Example 2 – Two measurements not within 0.4 cm each other

Stature measurement #1 158.2 cmStature measurement #2 162.9 cmStature measurement #3 162.6 cm

The above two measurements are not within 0.4 cm of each other; therefore, the median of the three

scores needs to be used, and the recorded score is 162.6 cm.

Determining a Velocity Curve

To determine the velocity curve, the increase in stature from one measurement time period to the next consecutive measurement time period is subtracted one from the other. For example, from 9 years to 10 years the increase in stature is 4.8 cm.

•By plotting the velocity curves it will be possible to clearly distinguish the rate of growth from one point in time to another.

•The velocity curve will immediately show distinctive growth points (for example, the onset of the acceleration in the curve, the peak in the curve and the deceleration in the curve).

• Protocol for Standing Height Measurement

• The student stands erect in bare feet with heels, buttocks and shoulders pressed against the stadiometre

• Heels together with arms hanging freely by the side (palms facing thighs)

• The tester applies gentle upward traction to the skull behind the ears

• The student is instructed to look straight ahead, take a deep breath and stand as tall as possible

• Draw down the measuring bar to the student’s head and record standing height to the nearest 0.1cm

The orbitale (O) is located on the lower or most inferior margin of the eye socket. The tragion (T) is the notch above or superior to the tragus or flap of the ear, at the superior aspect of the zygomatic bone. This position corresponds almost exactly to the visual axis when the subject is looking directly ahead.

Protocol for Sitting Height MeasurementProtocol for Sitting Height Measurement

• Athlete sits on the base of the stadiometre with knees slightly bent. Hands rested on knees

• The buttocks and shoulders rest lightly against the standiometre, which is positioned vertically behind the student. Ensure there is no gap between buttocks of student and stadiometre

• The tester applies gentle upwards traction to the skull behind the ears to ensure the trunk is fully stretched

• Draw down the measuring bar to the students head and record sitting height to the nearest 0.1cm

• Once sitting height is calculated, it can be subtracted from the stature

Protocol for Arm Length MeasurementProtocol for Arm Length Measurement

• Mount a tape measure on the wall about shoulder height of the students being tested. Ensure the starting point of the tape measure is fixed to a corner of a wall. This is where the student’s fingers must be fixed

• The student stands erect with their stomach and toes facing the wall, feet together and head turned to the right

• The arms are extended laterally at shoulder level (horizontal) with palms facing forwards. Fingers stretched

• The tip of the middle finger is aligned with the beginning of the tape measure (corner of wall) and arms are out-stretched along the tape measure

• Use a ruler held vertically to the tape measure to record total arm span to the nearest 0.1cm.

• Windows of Trainability refers to the sensitive periods of accelerated adaptation to training, which occurs prior, during and early post puberty.

• All systems are always trainable, thus the windows are always open

• The window is fully open during the sensitive periods of accelerated adaptation to training and partially open outside of the sensitive periods.

Viru et.al. Age periods of accelerated improvements of muscle strength, power, speed and endurance in

the age intervals of 6 – 18 years.(Biology of Sport. Vol.15, No 4, pp.211-227)

• 31 studies and 11 reviews (peer reviewed, internationally verified)

• Cross sectional studies, number of subjects 83 to 21175• Longitudinal studies 65 to 90• Age range 6 to 18 years• Clearly defined endurance, strength and speed windows

• A remarkable increase in aerobic power was not observed in trained boys before the age of PHV.

• Beginning approximately 1 yr prior to the age of PHV and thereafter, training effectively increased aerobic power above the normal increase attributable to age and growth.

Rushall, B. The Growth of Physical Characteristics in Male and Female Children.

In: Sports Coach, Australia. Vol.20. No 64, Summer, 1998. pp. 25 – 27.(Electronic Version)

• “… studies at the International Centre for Aquatic Research in Colorado Springs have shown that swimmer’s aerobic capacity reaches its ceiling level at the time of the onset of the adolescent growth spurt.”

• Sport Science Summit for Young Swimmers: Learning about Athlete Development.

• VO2 max shows significant growth from 10-13 to 14 years and peaks between 17-21 for males and 12-15 for females.

• This time frame, when significant growth can occur (sensitive periods), should be maximised in training to develop the athlete’s long term potential

• Pre-pubescent athletes show significant improvements in long duration, low intensity events

• Coaches should optimise aerobic training during this “sensitive period” (12-15 for females / 17-21 years for males) to maximise athlete’s aerobic development.

• It is suggested that pre-pubescent athletes (ages 9-12/15) should focus on longer distances for reasons related to both skill development and aerobic capacity development.

AEROBIC VS ANAEROBIC TRAINING [rationale]

Pre-pubescent children are more predisposed to extensive aerobic training since heart size and blood volume increase in proportion with body size (peak increase of heart size in boys - at the age of 13-14 years; in girls 11-12).

Intensive training exercises should be applied with caution and their volume increased gradually.

A.R.Vorontsov,

THEORY OF SENSITIVE (critical) PERIODS IN PHYSICAL DEVELOPMENT AND MOTOR

LEARNING

Maximal effect on growth patterns and development of motor abilities may be achieved by: 1) exposing juvenile athletes to specialized training during the periods of rapid growth 2) changing training accents and content in accordance with the rhythm of the growth

A.R.VorontsovA.R.Vorontsov,,

Theory of “Sensitive Periods” in motor learning and development

• Purposeful training for development of cardio-respiratory and vascular systems may be effectively used in pre-pubescent and early in pubescent periods of individual development. This training aims first the development of aerobic capacity and efficiency.

• Onset of growth spurt and maturation - most appropriate time for development of aerobic power (VO2 max)

• Training of maximal strength and anaerobic endurance will be most efficient in post-pubescent young athletes.

MYT should be subdivided into stages in accordance withparticularities and rhythm of the growth and development

Aerobic Capacity Aerobic Power

• After the onset of the growth spurt train the aerobic system selecting non-weight bearing training methods (i.e., stationary, mountain or road bike, treadmill, swimming or water running, rowing or kayaking,etc.)

• Keep weight bearing training for sport-specific technical-tactical training

The Trainability of the Five SThe Trainability of the Five S’’ssStrength:Strength:

• Always trainable• Critical window of accelerated

adaptation to strength training:• Window 1 for females immediately

after PHV• Window 2 for females with the onset

of menarche• 12 – 18 month after PHV for males

Accelerated Adaptation to TrainingStrength

• Strength training before maturation is Central Nervous System training and motor coordination improvements

• Medicine balls• Swiss balls• Own body weight

• When the legs are growing train upper body and core (trunk)

• When the arms are growing train lower body and core

• When the trunk is growing train lower body and upper body and the core!

The Trainability of the Five S’sSpeed:

• Always trainable but declines with age• Sensitive period - window of accelerated adaptation

to speed training (Viru, 1995: Borms, 1986):• Males:

– Window 1: 7 - 9 years of age– Window 2: 13 – 16 years of age

• Females: – Window 1: 6 – 8 years of age– Window 2: 11 – 13 years of age– (Chronological age)

• Paradigm shifts in coaching – speed all year round

SpeedSpeed

• Window 1 is agility, quickness window.• Change of direction, linear, lateral and multi

directional speed• Segmental speed• Duration of intervals less then 5 seconds

• Window 2 is anaerobic alactic power and capacity window

• Linear, lateral, multi directional and chaotic speed• Duration of intervals 5 – 20 seconds

• It should be noted that speed should be trained all year round regardless of the annual phases of training

• It should be trained at the end of the warm-up (no CNS or metabolic fatigue) – thus, no interference with any other training activity and the volume should be low

• Appropriately periodized “block” speed training should be implemented within the annual cycle

• These speed training blocks should be longer during the sensitive periods for speed training

Skill - Review ArticleJan Borms - The child and exercise: an overview

Journal of Sports Sciences, 1986, 4, 3-20

• Numerous publications have emphasized the importance of a “golden age” period to learn all kinds

of movement patterns”

• "Most authors agree that this sensitive period can be located between 9 and 12 years of age."

SkillSkill

• In late specialisation sports the window is open longer, (until the onset of PHV) especially when the fundamental movement and fundamental sports skills have been acquired

• The onset of PHV will have a strong negative impact on skill acquisition

• However, as a policy, we want to encourage all sports to develop fundamental movement and sports skills before age 12-13

Training PrioritiesTraining Priorities

• During the General Preparatory Phase and the Specific Preparatory Phase the sensitive periods of accelerated adaptation to stamina, strength, speed, skill and suppleness should be prioritized

• Competition programs should be carefully planned and are secondary in importance to optimal training (exploiting the periods of accelerated adaptation)(Viru, 1995)

• “Adolescent maintenance” should be introduced in early specialization sports

ConclusionConclusion

• Children are not miniature adults– Physical, mental-cognitive and emotional development

• Monitor growth– Proper measurements

• Reactive periodization– Adjust the training, competition and recovery programmes

to the tempo of growth

• Ensure that “adolescent maintenance” will be implemented when required in all sports
