Which principle of training is used when a person increases the number of repetitions of an exercise?

Summary

• Resistance training increases muscle strength by making your muscles work against a weight or force.
• Different forms of resistance training include using free weights, weight machines, resistance bands and your own body weight.
• A beginner needs to train two or three times per week to gain the maximum benefit.
• Complete the adult pre-exercise screening tool and consult with professionals, such as your doctor, exercise physiologist, physiotherapist or AUSactive registered professional before you start a new fitness program.
• Rest each muscle group for at least 48 hours to maximise gains in strength and size.
• Varying your workouts can help you push past a training plateau.

In order to get the most out of your training, you need to apply these key principles of training – overload, specificity, reversibility and variation.

Overload

In order to progress and improve our fitness, we have to put our bodies under additional stress. Applying this training principle will cause long-term adaptations, enabling our bodies to work more efficiently to cope with a higher level of performance the next time we train.

Overloading can be achieved by following the acronym FITT:

• Frequency: Increasing the number of times you train per week or the number of reps you perform.
• Intensity: Increasing the difficulty of the exercise you do. For example, running at 12 km/h instead of 10 or increasing the weight you are squatting with.
• Time: Increasing the length of time that you are training for. For example, cycling for 45 minutes instead of 30.
• Type: Increase the difficulty of the training you are doing. For example progress from walking to running, from accessory to free weights.

Specificity

This principle relates to the type of training that you do. It should be specific to you and your chosen sport. You should train the energy system which you use predominantly (e.g. a runner and weight lifter will require different processes), and the fitness and skill components most important to your sport, for example, agility, balance or muscular endurance. You should also test the components which are important in your sport to see your strengths and weaknesses, such as imbalances, speed, power, posture etc.

So this principle means you should consider what key conditioning you can work on, in order to boost your performance.

Reversibility

You can lose what you've gained if it's not maintained. If you stop training then the improvements you have made will be reversed. So if you do not train for a period of time, or reduce the amount you are training, you may not be able to resume training to the same level as before, so it’s important to build the body back up progressively until you reach that level again.

You want to be careful with overtraining though. It is a very common problem when you don’t get enough rest during your training schedule, overdoing workouts to a point where it is having adverse effects on your results and progress. This should not be confused with overload, which is the planned exposure to an increased workload and the right amount of rest in-between. Without the correct amount of rest, you will suffer from overtraining and your body won’t be able to correctly and safely perform the movements you need it to.

Variance

Try to vary your training, to keep you interested and to give your body (and the muscles you’re using) a different challenge. This can be by switching up the movements to circuits in your usual training, or doing something else entirely. Many athletes will take part in a completely different sport in-between their main season to keep their fitness up whilst still having a rest! 

Experts recommend that training programs should limit periods of complete inactivity to no more than two to three weeks. Prolonged periods of inactivity should be avoided, and your training programme should incorporate some form of "maintenance" training where an extended break is desired.

Think about your current training. Do you incorporate the above? If not, it's worth considering each principle and adding the relevant elements into your routine, so you can maintain and progress as best as possible.
