A Balanced Diet and Exercise Improve Reproductive Ability

A healthy exercise routine combined with a balanced diet is an excellent way to improve fertility associated with ovary-related disorders in women. Exercise reduces high stress levels linked to the development of heart and blood vessel diseases and depression, which subsequently can have negative effects on female ovulation (formation of eggs in the ovary) and menstruation.

A 2007 study by researchers at the Harvard School of Public Health found that women who exercise and eat a balanced diet containing reduced amounts of saturated fats, more dairy products and less meat had less ovulation problems.1 A more recent study on a group of infertile, obese women has shown that a 12-week program of specific diet and exercise has favorable effect on the metabolic and menstrual parameters in these women.2

Evidence-based guidelines also indicate that a regular exercise routine before and during gestation is an important part of a healthy pregnancy. In addition to maintaining physical fitness, a healthy exercise routine may also be beneficial in preventing or treating many diseases affecting the mother and her child growing in the womb.3

Furthermore, some specific yoga postures may increase fertility, as these postures help to stimulate the blood flow to the reproductive system, stimulate ovulation and make the uterus healthier for conception.4 Therefore, this type of physical activity can also be used as an adjunct to infertility treatment.

Exercise Benefits HIV/AIDS Patients

Exercise is a key strategy employed in the rehabilitation of HIV/AIDS patients in order to address problems such as bodily impairments (pain or weakness), activity limitations (such as inability to walk) and participation restrictions (problems faced in life situations such as inability to work). In addition, exercise has clinically significant effects on immune responsiveness (the body’s ability to oppose infections) of HIV-infected patients, causing a slowdown on the progression of the disease.

An analysis on the safety and effectiveness of aerobic exercise interventions in adults living with HIV/AIDS confirmed that aerobic exercise is safe and beneficial for HIV/AIDS patients. The study noted improvements in the immune response, heart and lung functions and psychological behavior in those individuals studied. 1 Similarly, another study stated that aerobic exercise for at least 20 minutes at a minimum of three times per week for four weeks appears to be beneficial and safe for adults living with HIV/AIDS.2 Further, supervised aerobic exercise training has also been shown to safely decrease fatigue, weight, and fat reduction in HIV-infected individuals.3

The benefits of aerobic exercising may result from the direct effect on immune response adjustment (exercise boosts the immune system) or from the psychological effects of exercise. Regular physical exercise helps to slow HIV progression and raise HIV patients’ blood count of certain specialized cells known as CD4 cells. CD4 is a type of white blood cell that helps in protection against infections and is specifically targeted by HIV. The higher the CD4 count in the blood, the better the ability of the patients to resist infections.

Moderate Exercise Boosts the Body’s Defense (Immune) System

Regular sessions of moderate exercise has been linked to an improvement in the body’s defense (immune) system, which could protect individuals against infections of the throat and nose (commonly referred to as parts of the upper respiratory tract). 1 People who exercise regularly report fewer incidences of colds than those who lead sedentary lifestyles. Regular, consistent, moderate exercise can lead to substantial benefits in the immune system over the long term. Nevertheless, this benefit is not seen when people are doing intense exercise, as it may cause a temporary decrease in immune system function.

A long-term study in Columbia has demonstrated a 23% reduction in risk of upper respiratory tract infection in those engaging in regular physical activity compared to those who engage in irregular moderate-to-vigorous exercise.2 In addition, a recent study on the effect of exercise on the immune system of healthy older adults suggested that regular aerobic exercise appears to benefit the immune system by helping to balance the responses of the immune system and reducing the symptoms of inflammation.3

There are physiological changes in the immune system as a response to regular, moderate exercise. During moderate exercise, the immune cells circulate through the body more rapidly and have a better ability to kill the infecting pathogens (disease-causing bacteria or virus). Although the immune system returns to pre-exercise levels immediately after the exercise session, each session represents an expansion in the immune system surveillance, and this cumulative effect appears to reduce the risk of infection over the long-term.

Health Fitness Exercise Prevents Fatigue and Pain

Chronic fatigue syndrome (CFS) refers to a group of disorders commonly characterized by extreme tiredness (fatigue) that lasts for a long time and restricts the ability to perform everyday chores. Muscle aches, body ache and joint pains may also be noted in individuals suffering from CFS. Long-term physical inactivity can further complicate the symptoms of CFS and have detrimental effects on mood, energy level and an increase in the occurrence of other related disorders. A guided exercise program is the usually recommended intervention in such fatigue conditions. 1

In patients with CFS, a guided exercise program (that involves monitoring and documenting a person’s daily activity levels to establish a threshold point for experiencing chronic fatigue symptoms) was found to be an effective treatment in improving exercise and functional capacity, reducing fatigue syndromes and improving daily function.2

In a review of several studies by researcher M. Edmonds with the Cochrane Collaboration research group, both fatigue and quality of life in individuals suffering from CFS were shown to be improved with three months of health fitness exercise therapy. Patients who were on health fitness exercise therapy were less fatigued, less depressed, had better physical functioning, slept better and were able to work better, compared with patients who did not exercise. Compared to patients who were taking antidepressant as their only therapy, those who exercised had lesser fatigue and a better quality of life.3

Exercise Regularizes Bowel Movement and Relieves Constipation

Constipation is a common disorder of the digestive system that is often affects individuals for a long period of time and has a negative impact on the daily lives of such people. Persistent difficulty with bowel movements may lead to severe complications such as fecal impaction (accumulation of hard feces in the rectum that is difficult to expell without assistance) and life-threatening situations such as volvulus (twisting of a part of the bowel).

One of the key risk factors for constipation is physical inactivity. Regular exercise can help in reducing and preventing the incidence of constipation. Physical activity helps to tone and strengthen the muscles of the large bowel. It also helps to decrease the time taken for food to move through the large intestine, thus limiting the amount of water absorbed from the stool during the transition period.

Regular exercise may also relieve constipation in patients who suffer from irritable bowel syndrome, a functional bowel disorder characterized by mild to severe abdominal pain, bloating and alteration of bowel habits.1 In a study at University of Birmingham, Birmingham, United Kingdom, a 12-week exercise intervention program significantly reduced constipation and bloating symptoms in individuals suffering from irritable bowel syndrome.

A team of researchers from the Netherlands, led by a scientist known as A. M. De Schryver, concluded that, in middle-aged inactive people with constipation, it is advisable to promote regular physical activity. They noted that exercise would improve both the motility (capacity of demonstrating movement by independent means) of the intestines and the time taken for the stool to pass in the lower part of the intestine, thereby alleviating the symptoms of constipation.2

Love & Loss

In wake of the recent passing of Steve Jobs I’d like to share another powerful lesson he left us.
Enjoy.

Steve Jobs gave this as his second story of his Commencement Address at Stanford University on June 12, 2005.

Love and Loss

I was lucky. I found what I loved to do early in life. Woz and I started Apple in my parents garage when I was 20. We worked hard, and in 10 years Apple had grown from just the two of us in a garage into a $2 billion company with over 4000 employees. We had just released our finest creation – the Macintosh – a year earlier, and I had just turned 30. And then I got fired. How can you get fired from a company you started?

Well, as Apple grew we hired someone who I thought was very talented to run the company with me, and for the first year or so things went well. But then our visions of the future began to diverge and eventually we had a falling out. When we did, our Board of Directors sided with him. So at 30 I was out. And very publicly out. What had been the focus of my entire adult life was gone, and it was devastating.

I really didn’t know what to do for a few months. I felt that I had let the previous generation of entrepreneurs down – that I had dropped the baton as it was being passed to me. I met with David Packard and Bob Noyce and tried to apologize for screwing up so badly. I was a very public failure, and I thought about running away from the valley. But something slowly began to dawn on me – I still loved what I did. The turn of events at Apple had not changed that one bit. I had been rejected, but I was still in love. And so I decided to start over.

I didn’t see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.

During the next five years, I started a company named NeXT, another company named Pixar, and fell in love with an amazing woman who would become my wife. Pixar went on to create the worlds first computer animated feature film, Toy Story, and is now the most successful animation studio in the world. In a remarkable turn of events, Apple bought NeXT.

I returned to Apple, and the technology we developed at NeXT is at the heart of Apple’s current renaissance. And Laurene and I have a wonderful family together.

I’m pretty sure none of this would have happened if I hadn’t been fired from Apple.It was awful tasting medicine, but I guess the patient needed it. Sometimes life hits you in the head with a brick. Don’t lose faith. I’m convinced that the only thing that kept me going was that I loved what I did. You’ve got to find what you love. And that is as true for your work as it is for your lovers.

Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven’t found it yet, keep looking.

Don’t settle. As with all matters of the heart, you’ll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don’t settle.

Steve Jobs
1955-2011

Apple updated its website Wednesday to reflect the death of Steve Jobs.

Exercise Protects Your Joints from Pain and Disease

Arthritis is a common disorder characterized by pain and swelling in the affected joints. This condition is usually limited to certain specific joints such as the knees, hips or spine. Exercise can play a vital role in the management of arthritis. Regular physical activity can keep the muscles around affected joints strong, reduce bone loss and may help control joint swelling and pain. Regular activity increases lubrication to the supporting tissues of the joint and reduces pain and stiffness in these tissues.1

There are three main types of exercise that can be beneficial in arthritis:

  • Range-of-motion exercises that help to reduce stiffness and keep the joints flexible.
  • Strengthening exercises that help to maintain or increase muscle strength.
  • Fitness exercises that help to increase endurance.

Physical activity need not be strenuous to achieve health benefits. Older adults can obtain significant health benefits with moderate amounts of physical activity, preferably on a regular basis. The Arthritis Foundation recommends that active range of motion exercises be performed 1 to 2 times daily while strengthening training can be done 2 to 3 times per week. Fitness exercise is recommended 3 to 5 times per week.2 Range of motion exercises such as shoulder circles, leg swings and lying knee-to-chest pulls will improve the flexibility of joints and prevent gradual losses in motion.

In an extreme condition, a joint may need to be replaced completely to cure the painful joint condition.

Exercise is the cornerstone of rehabilitation therapy following total joint replacement for arthritis. Evidence shows that increased bone quality will improve fixation of the artificial joint and reduce the incidence of early loosening.3 Additionally, preoperative exercise prior to total joint replacement has been documented to significantly reduce the need of rehabilitation procedures following surgery.4

Exercise Helps in Prevention of Back Pain

Back pain is very common among adults and is often caused by muscle strain or injury. Regular exercise therapy, including stretching or strengthening may improve pain and function in individuals suffering low back pain for prolonged durations.1 Regular exercise may not only help decrease low back pain but may also prevent re-injury to the back, help in faster recovery and reduce the risk of disability from back pain. Some sources recommend that these exercises be done under appropriate supervised physical training.

A 2005 Swiss study concerning the long-term effects of exercise therapy in prevention of low back pain has shown that supervised exercise can effectively improve functional ability and reduce low back pain up to a period of one year.2 More recently, another study by Finnish researchers confirmed this long-term benefit of exercise by indicating that home-based exercise programs can reduce low back pain and the beneficial effects can be seen to last over five years.3

Other than reducing the need for physical therapy, doctor referrals and pain medication prescriptions, regular low-to-moderate aerobic exercise appears to improve the mood and work capacity in individuals suffering from low back pain.4 Exercises to reduce low back pain are not complicated and can be done at home without any special equipment. However, these exercises should be performed under appropriate supervised physical training to prevent further complications and to obtain maximum relief.
