Training Principles
Tools applicable to all clients to create good training programs for each individual
Overload Principle: the changes in body - training effect
*physical changes from training programs as a result of the overload principle can be the increase in red muscle, or increased amount of capillaries
Symmorphosis → the body is designed to reach an optimized threshold, but not exceed it.
The body builds and maintains just enough capacity to meet its regular workload (no more no less)
When physical demands increase, the body’s adaptations change increases systems such as cardiovascular, respiratory, and muscular systems (up-regulation)
Likewise, when the physical demands decrease, the body’s adaptations change to decrease those systems as the increased energy created by them is no longer necessary. (down-regulation)
Overload + Initial values = How much training you should give someone (inverted “U” model → tip of the arch is the greatest effect)
the amount of overload appropriate for an individual is dictated by their personal fitness level
Progressive Overload Principle:
the physiological systems of the body must continuously be taxed with greater than normal loads
once your body responds to the increase in total demands, by building that extra capacity you need to increase total demands again to see another response
Points
1) have a long-term plan for inducing maximum adaptation
2) 2-10% progression is useful for not adding too much nor too little (for athletes → measure in volume (intensity +time). , for healthy adults → measure in time)
3) for lower fit clients, don’t worry about variation
FITT - determines the amount of overload required for progression
Frequency, Intensity, Time, Type
determines how to employ the initial and progressive overload
Frequency: total number of exercise or structured PA bouts per week
Intensity: the rate of work or effort work (good measurement is weight)
Time: length of PA or exercise bout
Type: type of exercise or PA (important to be motivated and effective)
Intensity + Time → total stress on the body (Volume)
Specificity Principle:
the tissues or body systems that are activated by exercise given their natural placement
follow checklist
1) Component of fitness (e.g cardiovascular, muscular, respiratory system)
2) Mode of activity/exercise → e.g swimming
3) Energy systems involved →e.g if you want to improve your anaerobic then stress out your muscles with heavy lifting
4) Muscle groups involved → e.g goal of developing larger back muscles
**each specificity factor can have a ripple effect on other factors → transferability
Principle of reversibility → the body adjusts to lower levels of stress the same way it adjusts to higher levels of stress
Principle of maintenance → by reducing training frequency, the level of fitness can be maintained if the intensity and duration of remaining workouts are similar (e.g off season)
Example: if you stop putting aerobic exercise demands on your body, your VO2max capacity will decrease
Principle of rest and recovery:
rest = bodily state with minimal functional and metabolic activities
recovery = return to normal levels → homeostasis
*a true rest day can increase training effect and reduce the risk of chronic injury + illness
“niggles” → functional dysfunction (e.g a stiff shoulder)
Principle of Individual differences → limits adaptability
biological ceiling (anthropometric, Cardiovascular-vessel diameter, Muscle morphology - fibre type compositions)
everyone has different genetics → individuals respond differently to exercise
Trainability → some more trainable athletes may require greater overload more quickly compared to the less trainable athletes
Principle of Diminishing Returns: (genetic ceiling, training, amount and quality of training, years spent training)
adaptation is lower as you near your genetic ceiling
e.g an athlete with good trainability but a low genetic ceiling (asthma) will respond fast to training effects, however they cannot overcome the disadvantage asthma has on their cardiorespiratory rate.
this principle helps conclude if adding more training to a persons program will be beneficial to them or not
Maturation Age → the performance of a mature adult and a junior athlete have a significant difference due to maturation age components
Menarche → first menstrual period age ~12-14→ optimal performance time
Principle of Transferability:
doing one sport or fitness activity or type of exercise can transfer to another sport or fitness activity
e.g Skiing → surfing (due to balance and the use of similar muscle groups)
