Almost Everyone Can Participate in Physical Activity.

When performing moderate-intensity activities in quantities that satisfy the Physical Activity Guidelines, most individuals are unlikely to get harmed. However, injuries and other negative occurrences do occur from time to time. Musculoskeletal injuries are the most frequent issues. Despite this, studies indicate that for every 1,000 hours of walking for exercise, only one injury occurs, and for every 1,000 hours of running, only four injuries occur.

Musculoskeletal injury risk is influenced by both physical fitness and overall quantity of physical activity. Physically fit individuals have a reduced risk of harm than those who are not. People who engage in greater physical exercise have a higher risk of injury than those who engage in less physical activity. People should: To engage in physical exercise safely and minimise the chance of injuries and other negative consequences, they should:

Recognize the dangers while remaining convinced that physical exercise is safe for almost everyone.

Because certain activities are safer than others, people should choose kinds of physical exercise that are suitable for their current fitness level and health objectives.

When additional physical activity is required to fulfil standards or health objectives, increase it gradually over time. Inactive individuals should “start small and build up” by progressively increasing the frequency and duration of their activities.

They can protect themselves by wearing proper clothing and sporting equipment, seeking out safe settings, adhering to laws and regulations, and making informed decisions about when, where, and how they exercise.

If they have persistent illnesses or symptoms, they should seek medical help. People with chronic illnesses and symptoms should discuss the kinds and quantities of exercise that are suitable for them with their health-care practitioner.

Select the Appropriate Activity Types and Amounts

People may lower their risk of harm by engaging in the right kinds of activities. The safest activities are those that are moderately intense and low impact, as well as those that do not entail intentional collision or contact. The activities with the lowest injury rates include walking for exercise, gardening or yard work, biking or exercise cycling, dance, swimming, and golf. Walking (a moderate–intensity, low-impact exercise) has a third or less of the injury risk of running in the quantities typically done by people (a vigorous-intensity and higher impact activity).

The risk of harm for a particular kind of physical exercise varies depending on the activity's aim. Bicycling for leisure or commuting, for example, causes less injuries than preparing for and participating in bicycle races. People who have previously injured a bodily part are at danger of hurting it again. By engaging in suitable levels of exercise and establishing acceptable personal objectives, the chance of injury may be minimised. Taking part in a range of physical activities may also help to decrease the risk of overuse injury. The difference between a person's normal level of activity and a new level of activity is directly linked to the risk of damage to bones, muscles, and joints.

Gradually increase your physical activity.

According to scientific research, the difference between a person's normal level of activity and a new level of activity is directly linked to the risk of damage to bones, muscles, and joints. The amount of overload refers to the magnitude of this gap. The danger of damage is reduced by creating a modest overload and then waiting for the body to adjust and recover. No matter what the person's current level of physical activity is, if more physical activity is required to achieve the Guidelines or personal objectives, physical activity should be increased gradually over time. Scientists have yet to develop a guideline for increasing physical activity progressively over time. The following suggestions provide basic advice on how to improve physical activity for sedentary individuals and those with low levels of physical activity:

To determine the degree of effort for aerobic exercise, use relative intensity (the intensity of the activity in relation to a person's fitness).

In general, begin with moderate-intensity aerobic exercise. Avoid activities that require a lot of energy, such as shovelling snow or jogging. Adults with a low degree of fitness may need to begin with light exercise or a combination of light and moderate activities.

First, increase the length (number of minutes per session) and frequency (number of days per week) of moderate-intensity exercise. Increase the intensity later if desired.

Keep track of the proportional magnitude of each week's increase in physical activity, since this is linked to injury risk. A 20-minute increase per week, for example, is safer for a person who walks 200 minutes per week (a 10% increase) than a person who walks 40 minutes per week (a 50 percent increase).

According to the current scientific data, adding a modest amount of light- to moderate-intensity exercise to one's regular activities, such as 5 to 15 minutes of walking each session, 2 to 3 times per week, has a minimal risk of musculoskeletal injury and no known risk of serious cardiac events. Because this range is so large, individuals should take three things into account when determining their rate of increase: age, fitness level, and previous experience. The length of time it takes to adjust to a new level of exercise is likely to be determined by age. Young people and young adults may probably safely increase their physical activity by a modest amount every week or two. It seems that older people need longer time to adjust to a new level of exercise, ranging from 2 to 4 weeks.

Physical Condition

While compared to fitter adults, less fit individuals are at a greater risk of injury when performing the same amount of exercise. Injury risk may be reduced if the rate of growth is slower over time. Because overweight and obese people are often less physically fit, this advice applies to them.
