What is the most basic principle in physical activity that indicates doing more than normal improvement to happen Brainly?

The Borg Rating of Perceived Exertion (RPE) is a way of measuring physical activity intensity level. Perceived exertion is how hard you feel like your body is working. It is based on the physical sensations a person experiences during physical activity, including increased heart rate, increased respiration or breathing rate, increased sweating, and muscle fatigue. Although this is a subjective measure, your exertion rating based on a 6 to 20 rating scale, may provide a fairly good estimate of your actual heart rate during physical activity* (Borg, 1998).

As you exercise you can rate your perceived exertion using several anchors. These include a rating of 6 perceiving “no exertion at all” to 20 perceiving a “maximal exertion” of effort. Practitioners generally agree that perceived exertion ratings between 12 to 14 on the Borg Scale suggests that physical activity is being performed at a moderate level of intensity. During activity, use the Borg Scale to assign numbers to how you feel (see instructions below). Self-monitoring how hard your body is working can help you adjust the intensity of the activity by speeding up or slowing down your movements.

Through experience of monitoring how your body feels, it will become easier to know when to adjust your intensity. For example, a walker who wants to engage in moderate-intensity activity would aim for a Borg Scale level of “somewhat hard” (12-14). If he describes his muscle fatigue and breathing as “very light” (9 on the Borg Scale), he would want to increase his intensity. On the other hand, if he felt his exertion was “extremely hard” (19 on the Borg Scale), he would need to slow down his movements to achieve the moderate-intensity range.

*A high correlation exists between a person’s perceived exertion rating times 10 and the actual heart rate during physical activity; so a person’s exertion rating may provide a fairly good estimate of the actual heart rate during activity (Borg, 1998). For example, if a person’s rating of perceived exertion (RPE) is 12, then 12 x 10 = 120; so the heart rate should be approximately 120 beats per minute. Note that this calculation is only an approximation of heart rate, and the actual heart rate can vary quite a bit depending on age and physical condition. The Borg Rating of Perceived Exertion is also the preferred method to assess intensity among those individuals who take medications that affect heart rate or pulse.

In order to get the most out of your training, you must follow some basic simple training principles which are overload, specificity, reversibility, and variance.

Overload means we must put our bodies under more stress than normal in order for adaptive changes to be made. Specificity relates to ensuring the training done is specific to the sport or activity. Reversibility means if you don’t keep it up you will lose it and variance relates to varying the training activities.

What are the basic principles of training?

The basic training principles for all physical exercise are:

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 this higher level of performance. Overloading can be achieved by following the acronym FITT:

Frequency: Increasing the number of times you train per week

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 each session. 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.

Specificity

This principle of training relates to the type of training that you do. It should be specific to you and your sport. You should train the energy system which you use predominantly (i.e. don’t run 5,000 meters in training if you’re a sprinter!) and the fitness and skill components most important to your sport, for example, agility, balance, or muscular endurance.

Another example is to swim a lot in training and then expect your running to improve significantly. Your general fitness will improve so therefore your running may also improve, not nowhere near as much as if you focus on running instead of swimming.

You should also test the components which are important in your sport to see your strengths and weaknesses. With this information, you can focus on improving your weak points.

Reversibility

Use it or lose it! Basically, if you stop training then the improvements you have made will be reversed. So if you are ill or have a holiday and do not train for a period of time (even as little as a week) you may not be able to resume training at the point where you left off.

Variance

Try to vary your training. This keeps you interested and gives your body different challenges. Remember a change is as good as a rest with this training principle. Many professional athletes will play a completely different sport in-between their main season, to keep their fitness up whilst still having a rest!

If you are new to exercise or are coming back from a long period of inactivity, there are things you should do to make sure that your exercise program is effective and brings benefits, not injury or pain.

Pre-exercise screening

Pre-exercise screening is used to identify people with medical conditions that may put them at a higher risk of experiencing a health problem during physical activity. It is a filter or ‘safety net’ to help decide if the potential benefits of exercise outweigh the risks for you, and whether you require referral to a GP or allied health professional prior to undertaking physical activity. Print a copy of the adult pre-exercise screening tool and discuss it with your doctor or exercise professional.

You may need to visit your doctor before starting physical activity

If you answer ‘yes’ to some of the questions from the adult pre-exercising screening tool, see a doctor before starting physical activity. These questions include:

• Has your doctor ever told you that you have a heart condition or have you ever suffered a stroke?
• Do you ever experience unexplained pains in your chest at rest or during physical activity and exercise?
• Do you ever feel faint or have spells of dizziness during physical activity and exercise that causes you to lose balance?
• Have you had an asthma attack requiring immediate medical attention at any time over the last 12 months?
• If you have diabetes (type I or type II), have you had trouble controlling your blood glucose in the last three months?
• Do you have any diagnosed muscle, bone or joint problems that you have been told could be made worse by participating in physical activity or exercise?
• Do you have any other medical condition(s) that may make it dangerous for you to participate in physical activity or exercise?

Setting goals for physical activity

Setting goals gives you something to work towards and provides you with a way to measure how well you are doing over a period of time. When it comes to succeeding at your exercise program, setting goals and monitoring your progress will help you stay on track and get you to where you want to go.

One of the first steps is to identify why your health is important to you. Ask yourself what you want to get out of becoming more active. Think about the benefits you want to experience if you choose to be more active, as well as the barriers that are holding you back. It may be helpful to make a list of the pros and cons. Which barriers do you feel strongest about? What are the benefits that you want to experience?

Start physical activity gently

If you are currently inactive or feel your fitness level is low, it is highly recommended that you consult a health or exercise professional before commencing activity. Otherwise, start gently with a short session of an activity that you feel you can manage. Build your confidence and fitness level with a number of short sessions.

Exercise progression is unique to every person, so if you have not exercised for some time, progress slowly. Increase the length and the intensity of your exercise session gradually. Don’t push yourself straight away. Injury or discomfort can occur and this may reduce your motivation levels.

Stretching, warming up and cooling down

As the name suggests, the warm-up is designed to increase your body’s internal temperature and warm your muscles to prevent muscle strains and joint sprains. The best way is to start off at a leisurely pace, and then pick up speed. Usually a 5 to 10-minute warm-up is all you'll need, but this will vary from person to person and if the weather is cold.

Start with light aerobic exercise such as walking, cycling or rowing – you can do these easily using the exercise machines at the gym, but if you are at home, here is another five-minute warm-up suggestion – and a few dynamic stretches.

Dynamic stretching involves slow, repetitive, controlled movements through the full range of motion, performing movements you will be using in your chosen physical activity. You can start slower, and with a smaller range of motion, and increase speed and range of motion gradually.

For the last five minutes of your exercise, slow down and allow your body to cool down gradually, letting your heart rate and breathing rate come back to normal.

Stretching suggestions

Stretching should be part of your warm-up and cool-down routines. Stretching can help prepare your body and mind for exercise. Recent research suggests that including dynamic stretching in your warm up, which focuses on the muscles you are about to use, is probably best.

Wear comfortable clothes and shoes for physical activity

Make sure you have comfortable clothing, a suitable pair of shoes and water (as well as sunscreen and a hat if you are outside). Your shoes should provide good support and the best type will depend on the activity you are doing. The wrong type of shoe may cause foot pain or blisters.

Getting the technique right for your chosen physical activity

If you are trying something new, or getting back into an activity you have not done for a while, it might pay to get some coaching or expert instruction. Depending on the activity, incorrect or poor technique may lead to injury or soreness.
