- Isometric exercises are when the muscle contracts without changing in length, like when you are flexing. An example of this type of exercise would be wall sits or planking.
- Isotonic exercises are when the muscle changes in length. there are 2 types of isotonic movements:
a. Concentric: this is when the muscle is shortening. Example, the upward motion when you do a bicep curl.
b. Eccentric: this is when the muscle is lengthening. Example, moving your arm back to straight from the bicep curl.
Isometric exercises are less stressful than isotonic exercises, so when individuals are recovering from an injury, they should start with isometric exercises and gradually move on the isotonic exercises.
There are 5 components of fitness:
Some may call it the 4 components of fitness as they combine muscular strength and muscular endurance.
To prevent yourself from getting injured, living a healthy lifestyle is a form or primary prevention. Warming up before you exercise, eating healthy, and exercising prevent injuries and illnesses.
2. Secondary prevention
If you do get injured, secondary prevention prevents further damaging the injury and trying to recover. This can be done by rehab, antibodies, bracing etc.
3. Tertiary Prevention
This level of prevention is for catastrophic injuries that people cannot recover from and return to their pre-injury condition. These people will work to to improve quality of life
Body mass index (BMI) is a tool we use to compare our weight to height by using a chart. It can be calculated by the equation BMI= (weight/height²), where weight is in kilograms and height is in meters. Many assume that this number can accurately depict a human of being overweight, underweight or at a health risk. BMI is a good indicator for the overall population but not for an individual. Someone could be categorized as obese in the BMI chart but that doesn’t mean this person is obese or unhealthy, they could just have a lot of muscle, for example a bodybuilder. For a BMI rating to accurately describe an individuals body composition it must be accompanied by the waist circumference.
|30.0 and above||Obese|
Carpal Tunnel Syndrome (CTS) is a chronic condition in the wrist area that can affect the arm and hands. An individual with CTS may experience numbness, tingling, and weakness in the affected hand. CTS is caused by the compression of the median nerve due to inflammation which runs through “carpal tunnel”. The carpal tunnel consists of the carpal bones (wrist bones) which create the base of the “tunnel” and the transverse carpal ligament that creates the roof.
Compression of the median nerve can be caused by many different aspects, most commonly due to the overuse of the wrist in an overextended position. Many individuals spend most of their time typing on the computer either due to work or gaming, the position the wrist is in when typing is in this overextended position and are more at risk for CTS. It is important to take notice of your hand position and make sure there aren’t long periods of time in the overextended position. If you are in this position due typing, ergonomic keyboards or rests for your wrist can help with the positioning.
There are many ways to maintain a good posture and avoid the experience of back pain.
- Pay attention to your standing and sitting posture throughout the day.
- If you are sitting for long periods of time, stand up and move around every 30 minutes to an hour.
- A rolled towel can be used to maintain the normal lumbar curve while sitting.
- Doing physical activity regularly can help build strong abdominal and back muscles.
- Aquatic exercises can help with your strength, posture, and balance.
- Phones or books should be held at eye level.
- Make sure your shoes are comfortable and supportive.
- Consider placing a small pillow under your neck and a rolled towel at your lower back when you sleep.
The plantar fascia helps support the arch of your foot. It is a thick band of tissue located at the bottom of the foot and connects your heel bone to your toes. Plantar fasciitis is when the plantar fascia becomes weak, swollen, and inflamed. Pain usually occurs with your first steps in the morning when you get out of bed or after sitting for a long time. Then the stiffness and pain decreases as you move more, however the pain may come back after long periods of standing.
People who walk, stand, or run for long periods of time are more likely to have plantar fasciitis. People who have high arches, flat feet, or tight Achilles tendons or calf muscles may experience plantar fasciitis. Overall, it is important to wear well fitted shoes and shoes that are not worn out.
Someone who has gastroesophageal reflux disease (acid reflux) can experience heartburn. A painful burning occurs behind the breastbone and you may feel pain that goes up toward your throat. When you lie down or bend over, the pain will get worse. You may have the feeling that food is entering back into your mouth. These symptoms usually occur after you finish a large or spicy meal.
Angina (when there is not enough blood flowing to your heart) can cause pain in your chest. Angina or a heart attack can cause tightness, squeezing, pressure, or dull pain in the middle of the chest. The pain can radiate to your neck, shoulders, or arms. Moreover, you may have trouble breathing, have an irregular heartbeat, or feel lightheaded, weak, or dizzy. Extreme stress or physical activity can lead to these symptoms.
A high-arched foot can cause someone to have too much weight on the ball and heel of the foot when he or she is walking or standing. The heel of the foot is tilted inward and leads to an unstable foot. Therefore, a high-arched foot can increase the risk of getting an ankle sprain.
One may experience symptoms, such as pain when standing or walking and on the ball, side or heel of the foot one may find calluses. Also, hammertoes (bent toes) or claw toes (toes clenched like a fist) may be present. In some cases, one may drag his or her foot when he or she takes a step due to the weak muscles of the foot and ankle. This is known as foot drop. Therefore, custom orthotics can be used to help treat a high-arched foot because it gives us stability and acts as a cushion for the foot.
Flat feet (pes planus) is usually a painless condition in which the arches of your feet are flattened and when you are standing the entire soles of your feet touches the floor. Flat feet can change the alignment of your legs and can lead to knee and ankle problems. Infants and toddlers have flat feet since the arches of their feet have not yet developed. As they get older, the arches will develop. However, some people’s arches never develop and this would lead to flat feet. A foot or an ankle injury, aging, rheumatoid arthritis and obesity can all increase your risk of flat feet. One may experience pain in the heel or arch area of the foot and the pain may get worse with activity. Orthotics or supportive shoes can help reduce symptoms and make your feet feel more comfortable.
