Knee strengthening exercises



This routine of knee strengthening exercises will challenge your thigh, hip and leg muscles to improve your strength and balance. Building the support for your knee joint in this way will also help improve your resistance to injury.
As you’ll see below, each exercise can be adjusted to your ability level so you get the right intensity for your workout. Follow the illustrations, instructions  so your routine will be both challenging and safe!







 Prone Leg Curls

(starting position) Reach the top of your head and feet in opposite directions until your upper body, knees and feet are off the floor. Hold your arms straight and squeeze your shoulder blades and your thighs together. From the starting position, bend and straighten your knees slowly, keeping your knees off the ground throughout the exercise. Also keep your knees as close together as possible--squeeze a pillow between your knees if that helps. Repeat 12-15 times. Add light ankle weights to increase the challenge.







 Step ups

Begin with your R foot up on a 9” stair step. Raise up to stand fully upright, and then raise your L knee up toward your chest, driving your R arm up at the same time. Lower slowly in 2-3 seconds to return to the starting position. As you go down, touch your R toes to the ground, but try not to put all of your weight in your foot before you start back up. To increase the challenge, work from the second step, or use a higher platform .Repeat up to 15-20 times on each side.









3 Single leg bridge

Knees bent and feet flat on the floor as above with your heels spaced comfortably from your bottom. Raise your bottom upward slowly until there is a straight line from your shoulders to your knees. Hold this position and stretch your R leg out. Hold 5 seconds, put the R leg back and stretch your L leg out. Repeat 2-3 times for each leg, lower to the start position for a brief rest, and then repeat the entire sequence.







Are you not quite ready for these knee strengthening exercises?

To build up to exercise 1, start with hamstring sets, standing leg curls, . To prepare for exercises 2 and 4, practice the intro routine here, and also try exercise 6 below. You’ll be ready to work on the single leg bridge once you can hold a 2 leg bridge with good form for 20-30 seconds. If you find exercise 5 difficult, practice this routine to build your core strength.





4 Lunge

Step backward with your right foot and lower your weight toward the ground. Stop at the point where you can feel your muscles working. Hold for 10-15 seconds. Keep both of your feet pointing forward and keep your left knee centered over your ankle. Also do not let your knee go forward past your toes. Use a wall to help with balance if needed. Repeat 4-6 times each side.

As with the other knee strengthening exercises, you can adjust this move to match your ability level. A larger, deeper step will make the exercise much more challenging if needed. If this exercise is too difficult, it's fine to skip this one and focus on the other exercises for now.
Are knee problems slowing your progress? Get specialist advice on how to beat knee pain.







5 Stability ball curls

Put your feet up on a stability ball as shown. With your arms on the floor to help you balance, lift your waist up to form a straight line from your shoulders to your knees. Hold this position and curl the ball underneath your legs. Don’t let your body sag toward the floor during the exercise. Straighten your legs all the way and repeat 8-12 times. If this exercise is difficult, start by balancing with straight legs, then do small curls and work your way up.









6 Wall slides


Stand with your back against a wall and step your feet out from the wall about 18”. Then lower yourself down into a squat. As with the lunge, stop at the point where you can feel your muscles working. Keep both of your feet pointing forward and keep your knees centered over your ankles. Hold for 15-20 seconds and repeat 3-5 times. You can squeeze a volleyball or playground ball between your knees during the exercise to isolate the inner quads. This exercise can also be done with a stability ball. Lean against the ball so that your waist is against the center of the ball. Of course, the deeper you go, the more challenging the exercise. Just don't go past a 90 degree angle so that you avoid excessive stress on your knee. The same goes for #4.

BMI Calculator: Are You Overweight?

Do you really need to lose weight? The BMI Calculator above will figure out your body mass index category (underweight, normal weight, overweight, or obese(A condition characterized by excess body fat )

  • This body mass index calculator is based on the standard BMI measurement that takes your weight in kg and square of the persons height in meters.

  •  Basically it tells you if you have an unhealthy body weight. It works for adults, both men and women above age 19. It is a good indicator of the amount of body fat you have, which is directly related to the risk of various diseases.

The BMI calculator uses the following weight categories for your BMI score:

Underweight   = less than 18.5

Normal weight = 18.5 - 24.9

Overweight    = 25.0 - 29.9

Obese         = 30.0 or greater
       


  • Body Mass Index (BMI) represents an index of body weight in relation to height. While BMI is not a measure of body fat, it is recommended as a more accurate way to assess body fatness than measuring weight alone.

In general, people with BMI in Normal range have the lowest health risks.

However, higher BMI does not always mean that a person has too much fat. Although BMI correlates with body fat level, it is not the perfect tool for evaluating the health risks associated with obesity. For example, athletes may have BMI which is higher than Normal because they have more muscle and thus weigh more than average people. But despite their high BMI, they are fit and in good health.

At the same time, BMI which is lower than Normal is usually associated with either extreme natural leanness or, in a worse case, with malnutrition or even starvation.

Scope of problem:

A national health problem : over weight  and obesity

Health risks associated with obesity :
                                                             Hyper tension ,hyper lipidemia ,Type 2 diabetes ,cardio vascular disease ,gall bladder disease ,stroke ,menstrual irregularities ,infertility and cancer(endometrium ,breast ,prostate ,colon)

Causes:

  • An imbalance when energy intake exceeds energy consumption.excess calories are consumed,exceeding those expended through exercise and activity.                                 
  • interaction of psychological and environmental factors(behavioral ,cultural ,social,economic factors)
  •    Genetic factors
  •   Endocrine and metabolic disorder(metabolic syndrome)

Prevention and management:


Life style modifications:

  •   Combination of dietary changes to reduce body weight combined with increased physical activity.
  •  Personalized diet with reduced caloric intake :fat intake with less than 30% of total energy intake ,emphasis on fruits,vegetables,whole grains and lean protein.
  •   Personalized exercise program,including stretching exercises,resistance exercises and aerobic exercises.
  • Instruction in ,self-monitoring of exercise responses(heart rate ,perceived exertion)

Behavior therapy:

  • Self monitoring of eating habits and physical activity(use of a food and exercise diary)stress management .
 
Pharmacology : Before taking any medications please consult your doctor.


  •   Over the counter (OTC) and prescriptive weight loss therapy                       (eg:sibutramine,orlistat)

Surgery(bariatric surgery):

  •   Limited to persons with BMI over 40(or individuals with comorbid conditions and a BMI over 35)
  •   Procedures include gastric banding and gastric bypass.

Exercise prescription:

  •  Before doing any exercises please consult your physical therapist.
  • Start slowly ,provide adequate warm –ups ,cool down. initial   exercise intensity should be moderate(40%-60%HRR)
  • Increase intensity gradually in order to prevent injury :moderate-intensity activity(50%-70% HRR)
  •   Frequency: 5-7 days/week.
  •   Duration:45-60 minutes
  •  Use of circuit training in order to combine resistive training with aerobic training activities.
  •      Provide with short rests between activites/exercise bouts.
ü               Involve the patient in activity selection,incorporating individual preferences and likes.
ü           Aquatic exercise programs can assist in reducing musculo skeletal strain and injury.

Awesome Tips to prevent osteoporosis


 Osteoporosis is a disease of progressive bone loss associated with an increased risk of fractures.

Bone is a living tissue, comprising mainly calcium and protein. Healthy bone is always being remodeled; that is, small amounts are being absorbed in your body and small amounts are being replaced.

If more bone calcium is absorbed than is replaced, the density or the mass of the bone is reduced. The bone becomes progressively weaker, increasing the risk that it may break. Osteoporosis means "porous bone." This condition develops when bone is no longer replaced as quickly as it is removed.

 

The disease often develops unnoticed over many years, with no symptoms or discomfort until a fracture occurs. Osteoporosis often causes a loss of height and dowager's hump (a severely rounded upper back).


Causes of osteoporosis

Aging

Physical inactivity

Reduced levels of estrogen

Heredity

Excessive cortisone or thyroid hormone

Smoking

Excessive alcohol intake

Nutrition and Lifestyle

                        Poor nutrition, including a low calcium diet, low body weight, and a sedentary lifestyle .

Medications and Other Illnesses

                       Osteoporosis has been linked to the use of some medications, including steroids, and to other illnesses, including some thyroid problems.


 Female Athlete Triad:

 Problems Caused by Extreme Exercise and Dieting

Sports and exercise are healthy activities for girls and women of all ages. Occasionally, a female athlete who focuses on being thin or lightweight may eat too little or exercise too much. Doing this can cause long-term damage to health, or even death. It can also hurt athletic performance or make it necessary to limit or stop exercise.

Three interrelated illnesses may develop when a girl or young woman goes to extremes in dieting or exercise. Together, these conditions are known as the "female athlete triad.

  • The loss of bone tends to occur most in the spine, lower forearm above the wrist, and upper femur or thigh-the site of hip fractures. Spine fractures, wrist fractures, and hip fractures are common injuries in older persons.
A gradual loss of bone mass, generally beginning about age 35, is a fact of life for everyone. After growth is complete, women ultimately lose 30% to 50% of their bone density, and men lose 20% to 30%.

Women lose bone calcium at an accelerated pace once they go through menopause. Menstrual periods cease because a woman's body produces less estrogen hormone

  •  Clinical examination will assist in confirming diagnosis

Treatment

 Early treatment for osteoporosis is the most effective way to reduce bone loss and prevent fractures.

To prevent osteoporosis, slow its progression, and protect yourself from fractures you should include adequate amounts of calcium and Vitamin D in your diet and exercise regularly.


Calcium

  •  During the growing years, your body needs calcium to build strong bones and to create a supply of calcium reserves. Building bone mass when you are young is a good investment for your future. Inadequate calcium during growth can contribute to the development of osteoporosis later in life.
  • Whatever your age or health status, you need calcium to keep your bones healthy. Calcium continues to be an essential nutrient after growth because the body loses calcium every day

 Although calcium cannot prevent gradual bone loss after menopause, it continues to play an essential role in maintaining bone quality. Even if women have gone through menopause or already have osteoporosis, increasing intake of calcium and Vitamin D can decrease the risk of fracture.

  •  You can get calcium from dairy foods such as milk, cheese, and yogurt. Calcium is also naturally found in plant foods including broccoli, kale, and Chinese cabbage. Some foods have added calcium, like orange juice and breakfast cereals.

Most adults can get the recommended 1000 mgs over the course of a day by eating a packet of fortified oatmeal, a cup of calcium-fortified orange juice, a cup of yogurt and half a cup of cooked spinach.

 Dairy products, including yogurt and cheese, are excellent sources of calcium.



Vitamin D helps your body absorb calcium. The recommendation for Vitamin D is 200-600 IU (international units) daily. Supplemented dairy products are an excellent source of Vitamin D. (A cup of milk contains 100 IU of Vitamin D

 Many foods have vitamin D, including:

Salmon, tuna, sardines, mackerel, and shrimp

                Egg yolks

                Beef liver

               Mushrooms

               Cod and fish liver oils

               Foods with added vitamin D, such as milk and some cereals, yogurt, and orange juices

The average adult would get more than a day’s recommended vitamin D by eating just one small can of pink salmon.

Another source of vitamin D is the sun. Your body makes vitamin D from sunlight. But you need to wear sunscreen to protect your skin, and that blocks your body from making vitamin D. Also, it can be hard to make enough vitamin D from the winter sun, depending on where you live.


  • Some foods make it harder for the body to absorb calcium. In particular, sodas and carbonated beverages should be avoided, not just for bone health but for many nutritional reasons, including preventing obesity. Sodas decrease calcium absorption in the intestines and contain empty calories. Milk, calcium-fortified juices, and water are better beverage alternatives for all age groups.

Vitamin supplements can be taken if your diet does not contain enough of this nutrient. Again, consult with your doctor before taking a vitamin supplement. Too much Vitamin D can be toxic.

Because lost bone cannot be replaced, treatment for osteoporosis focuses on the prevention of further bone loss




  • Although exercise and nutrition therapy are often key components of a treatment plan for osteoporosis, If you're not getting all the vitamin D and calcium you need from food there are other treatments as well.

Estrogen Replacement Therapy

 Estrogen replacement therapy (ERT) is often recommended for women at high risk for osteoporosis to prevent bone loss and reduce fracture risk. A measurement of bone density when menopause begins may help you decide whether ERT is right for you. Hormones also prevent heart disease, improve cognitive functioning, and improve urinary function. ERT is not without some risk, including enhanced risk of breast cancer; the risks and benefits of ERT should be discussed with your doctor.

Selective Estrogen Receptor Modulators

 New anti-estrogen's known as SERM (selective estrogen receptor modulators) can increase bone mass, decrease the risk of spine fractures, and lower the risk of breast cancer.

Calcitonin

 Calcitonin is another medication used to decrease bone loss. A nasal spray form of this medication increases bone mass, limits spine fractures, and may offer some pain relief.

Bisphosphonates

 Bisphosphonates, including alendronate, markedly increase bone mass and prevent both spine and hip fractures.

ERT, SERMs, calcitonin, and bisphosphonates all offer patient with osteoporosis an opportunity to not only increase bone mass, but also to significantly reduce fracture risk. Prevention is preferable to waiting until treatment is necessary.








Physical therapy:

 Joint/bone protection strategies

Maintain /improve joint mechanics and connective tissue functions

Implementation of aerobic capacity/endurance conditioning or reconditioning,such as aquatic programs



Safe Exercise

When people begin a new exercise program, they often push their bodies too far and put themselves at risk for injury. The common notion that exercise must be really hard or painful to be beneficial is simply wrong. Moderation is the key to safe exercise. Safe exercise programs start slowly and gradually build up in intensity, frequency, and duration.

In addition, if you have an existing health problem, such as high blood pressure, diabetes, a history of heart disease, or are a smoker, you should contact your doctor before beginning any vigorous physical activity

Safe Exercise Guidelines

Use Proper Equipment

Warm Up. Warm up to prepare to exercise, even before stretching. Run in place for a few minutes, breathe slowly and deeply, or gently rehearse the motions of the exercise to follow. Warming up increases your heart and blood flow rates and loosens up other muscles, tendons, ligaments, and joints.

Stretch. Begin stretches slowly and carefully until reaching a point of muscle tension. Hold each stretch for 10 to 20 seconds, then slowly and carefully release it. Inhale before each stretch and exhale as you release. Do each stretch only once. Never stretch to the point of pain, always maintain control, and never bounce on a muscle that is fully stretched.

Take Your Time. During strength training, move through the full range of motion with each repetition. Breathe regularly to help lower your blood pressure and increase blood supply to the brain.

Drink Water. Drink enough water to prevent dehydration, heat exhaustion, and heat stroke. Drink 1 pint of water 15 minutes before you start exercising and another pint after you cool down. Have a drink of water every 20 minutes or so while you exercise.

Cool Down. Make cooling down the final phase of your exercise routine. It should take twice as long as your warm up. Slow your motions and lessen the intensity of your movements for at least 10 minutes before you stop completely. This phase of a safe exercise program should conclude when your skin is dry and you have cooled down.

Rest. Schedule regular days off from exercise and rest when tired. Fatigue and pain are good reasons to not exercise.


Exercise Regularly


Like muscles, bones need exercise to stay strong. No matter what your age, exercise can help minimize bone loss while providing many additional health benefits.

Doctors believe that a program of moderate, regular exercise (3 to 4 times a week) is effective for the prevention and management of osteoporosis. Weight-bearing exercises such as walking, jogging, hiking, climbing stairs, dancing, treadmill exercises, and weight lifting are probably best

 Loss of height and a stooped appearance of a person with osteoporosis results from partial collapse of weakened vertebrae.



Lifestyle Choices To Prevent Falls

 Maintaining your health and staying physically active can help to reduce your risk for falling.

Understand Your Health and Medications

Get an annual eye examination, and a physical that includes an evaluation for cardiac and blood pressure problems.

Maintain a diet with adequate dietary calcium and Vitamin D.

Do not smoke.

Avoid excessive alcohol intake.

Keep an up-to-date list of all medications and frequently provide it to all doctors with whom you consult.

Check with your doctor(s) about any side effects of your medications and over-the-counter drugs, as fatigue or confusion increases your risk of falling.

Make sure all medications are clearly labeled and stored in a well-lit area.

Take medications on schedule with a full glass of water, unless otherwise instructed.

Exercise

Talk to your doctor about starting an exercise program.

If possible, participate in an exercise program that aids agility, strength, balance, and coordination. Climbing stairs, jogging, hiking, dancing, weight training and other activities can help build bone strength and slow progression of osteoporosis, a disorder that causes bones to thin and weaken.

In addition, active pastimes, such as bicycling and gardening, also can improve health and life quality.

Footwear

Wear properly-fitting shoes with non skid soles. Avoid high heels.

Tie your shoe laces.

Use a long-handled shoehorn if you have trouble putting on your shoes.

Never walk in your stocking feet. Replace slippers that have stretched out of shape and are too loose.

Home Modifications To Prevent Falls

 Research shows that even simple safety modifications, such as those at home where most senior falls occur, can substantially cut the risk of falls and related injuries.

Bedroom

Place a lamp, telephone, or flashlight near your bed.

 Sleep on a bed that is easy to get into and out of.

Replace satiny sheets and comforters with products made of non a slippery material such as wool or cotton.

Arrange clothes in your closet so that they are easy to reach.

Install a nightlight along the route between your bedroom

Keep clutter off the bedroom floor.

Living Areas

Arrange furniture so you have a clear pathway between rooms.

Keep low-rise coffee tables, magazine racks, footrests, and plants out of the path of traffic.

Install easy-access light switches at room entrances so you will not have to walk into a dark room in order to turn on the light. Glow-in-the-dark switches also may be helpful.

Walk only in well-lighted rooms, stairs, and halls.

Do not store boxes near doorways or in hallways.

Remove newspapers and all clutter from pathways.

Keep electric, appliance and telephone cords out of walkways, but do not put cords under a rug.

Do not run extension cords across pathways; rearrange furniture.

Secure loose area rugs with double-faced tape, tacks, or slip-resistant backing.

Do not sit in a chair or on a sofa that is so low that it is difficult to stand up.

Repair loose wooden floorboards right away.

Remove door sills higher than a half inch.

Kitchen

 Remove throw rugs.

Clean up immediately any liquids, grease, or food spilled on the floor.

Store food, dishes, and cooking equipment within easy reach.

Do not stand on chairs or boxes to reach upper cabinets.

Use nonskid floor wax.

Stairs

Keep stairs clear of packages, boxes, or clutter

Light switches should be at the top and bottom of the stairs. Or, consider installing motion-detector lights which turn on automatically when someone walks by.

Provide enough light to clearly see each stair and the top and bottom landings.

Keep flashlights nearby in case of a power outage.

Remove loose area rugs from the bottom or top of the stairs.

Replace patterned, dark, or deep-pile carpeting with a solid color, which will show the edges of steps more clearly.

Put non-slip treads on each bare-wood step.

Install handrails on both sides of the stairway. Each should be 30 inches above the stairs and extend the full length of the stairs.

Repair loose stairway carpeting or wooden boards immediately.

Bathroom

 Place a slip-resistant rug adjacent to the bathtub for safe exit and entry.

Mount a liquid soap dispenser on the bathtub/shower wall.

Install grab bars on the bathroom walls.

Keep a nightlight in the bathroom.

Use a rubber mat or place nonskid adhesive textured strips inside the tub.

Replace glass shower enclosures with non-shattering material.

Stabilize yourself on the toilet by using either raised seat or a special toilet seat with armrests.

Use a sturdy, plastic seat in the bathtub if you cannot lower yourself to the floor of the tub or if you are unsteady.

 What to Do If You Fall

 Do not panic. Assess the situation and determine if you are hurt.

Slide or crawl along the floor to the nearest couch or chair and try to get up.

If you cannot get up, call for help.
