What principle of training is improved by increasing the frequency or intensity of the physical activity normally done?

Every Personal Trainer should have The Exercise Principles as a foundation for their programme design work with clients.

With 79% of adults participating in sport and recreation activities every week and 34.9% of adults currently signed up to a fitness club or center, it’s fair to say that physical activity plays a large role in peoples lives in New Zealand.

Whether people take part in activity for enjoyment or because they’re aiming to achieve a specific goal, exercise will place stress on our bodies.  Understanding exercise principles allows trainers to monitor the stress (exercise load) placed upon their client in order to make the training safe and effective, helping the client to achieve their goals.

So let’s take a look at the principles, their definitions and what they actually mean in lay terms.

Individualisation

Exercise should be specific to the individual completing the training.

People respond differently to exercise so in order to maximise the benefits, therefore training programmes should be built around the person’s needs and capabilities.

Specificity

Exercise should be specific to the client’s goals, needs and capabilities.

Our bodies response to training is based on the specific stimulus (training) applied.  So, to increase adaptation (results) exercise should be specific to an individual’s goals, tasks, movements and capabilities.

Overload

Exercise should overload the body in order for a positive adaptation to occur.

For the body to adapt it needs to be overloaded.  This means it needs to be placed under greater stress than it is accustomed to.

This is accomplished by using the F.I.T.T principle to make the body do more than it has done before.

F = Frequency of training

I = Intensity of training

T = Type of training

T = Time of training (duration)

Progressive Overload

Exercise needs to continually overload the body if positive adaptations (change) are to continue to take place.

For the body to keep adapting to exercise the stress it is placed under should progressively increase.  Therefore, the intensity and loads should continually increase over time.  Similar to overload, stress can be gradually increased using the F.I.T.T principle.

Variety

Exercise needs to be varied for optimal adaptation to occur, avoiding boredom, overuse, injury or hitting a plateau.

For optimal change to occur and to decrease the risk of an individual getting bored, overtraining, getting injured or reaching a plateau, the training must constantly be varied.

Rest and Recovery

Rest and recovery are required to allow the body time to adapt to exercise.

Optimal adaptation requires recovery time.  It is only during the recovery phase (days between workouts) that the body is able to change and adapt to the stress of the workout.

Recovery can be improved in a variety of ways, such as effective nutrition and hydration, light aerobic exercise and stretching sessions.  It is believed that 90%+ of an individuals time is spent recovering from exercise. If we get this wrong positive adaptations will not occur as quickly.

Reversibility

If you don’t use it you lose it.

Adaptations which occur through exercise are reversible, so when training is stopped for prolonged periods the adaptations from previous exercise will be lost.

Maintenance

Fitness can be maintained by altering the F.I.T.T principle.

By maintaining the intensity of training and decreasing the volume or frequency of training by 1/3 – 2/3 the current fitness levels of an individual can be maintained.

Ceiling

Room for positive development decreases the fitter you become.

As we get fitter, the amount of improvement possible decreases based on the client getting closer to their genetic potential (ceiling).

Interference

Training contrasting fitness components at the same time can reduce adaptation (results) in both.

Training certain components of fitness at the same time can lead to interference.  For example, training to increase muscle size and increase aerobic endurance at the same time will lead to the client making slower progress to both goals, even though there will be increases in both of the components being trained.

We Know the Exercise Principles… Now What?

It’s imperative that every fitness professional understands the exercise principles and how to use them with clients.  Abiding by the principles will help trainers create a safe, injury free, exciting and effective programme, allowing clients to achieve their goals.

What principle of training means that fitness is improved by increasing the frequency or intensity of the physical activity normally done?

According to the principle of overload, an individual must work (“load”) the body using a step-by-step increase in physical activity duration, time, and/or intensity in order to facilitate optimal fitness improvements (American College of Sports Medicine, 2013). This step-by-step increase is often known as progression.

What is the principle of training frequency?

Overload and progression can be applied to training using the FITT principle. Frequency is how often you train, for example, three times a week. Frequency is increased by training a greater number of times each week. Intensity is how hard you train, for example faster, heavier, less recovery.

What is the principle of exercise intensity?

The FITT principles are an exercise prescription to help participants understand how long and how hard they should exercise. FITT is acronym that stands for Frequency, Intensity, Time, and Type. FITT can be applied to exercise in general or specific components of exercise.

What principle of exercise states that the only way to improve fitness is to increase one variable such as resistance or repetitions as your fitness level improves?

The overload principle is one of the seven big laws of fitness and training. Simply put, it says that you have to increase the intensity, duration, type, or time of a workout progressively in order to see adaptations. The adaptations are improvements in endurance, strength, or muscle size.
