Aerobic Exercise Improves Mental Performance for Divers

Aerobic Exercise Improves Mental Performance for DiversThe “runner’s high,” a “feel better” sensation often experienced by long-distance runners, is generally attributed to high levels of endorphins in the the brain. Researchers have known for some time that exercise increases endorphin production. In addition to improving the efficiency of the heart, lungs and vascular system, aerobic training can actually produce an anti-depressant type of effect including improvements in emotional and intellectual health.

Aerobic exercise improves mood stability often allowing those under a doctor’s care to reduce anti-depressant and anxiety medications. Improvements in self-esteem, increased confidence, and a more positive outlook for the future are also benefits of the effects of physical activity on brain chemistry.

Studies indicate that aerobic exercise improves mental acuity resulting in better concentration, enhanced ability to direct thoughts, and improved memory, all important mental performance activities for divers. Further neurophysicological advantages include a reduction in the symptoms of diseases such as Parkinson’s, improved sleep patterns, and diminishing the craving responses during smoking cessation.

Cardiorespiratory fitness is essential for scuba diving. Incorporating aerobic exercise in the diver’s daily routine is definitely not a “no-brainer” but it isn’t difficult to achieve. The results of the above-mentioned studies were accomplished in only five weeks with 30 to 60 minutes of exercise three times a week.

Examples of aerobic exercise are walking, jogging, running, swimming, rowing, cycling, jumping rope, aerobics classes, and dancing. Fitness centers and home gyms provide equipment such as treadmills, stairclimbers, ellipiticals and exercise bikes. Aerobic exercise may also be performed outdoors almost anywhere and can be a family activity, social time for moms while children are at school, or tranquil time alone.

Being Coachable

Whether learning to scuba dive or accomplishing goals for scuba fitness; Being Coachable is a mature attitude of learning and collaboration essential to being a healthy and competent diver.

Sporty womanRecently I won a gift certificate for a month of fitness classes. As a fitness professional in high demand my schedule is usually booked. As a necessity my own workouts are typically self-trained sessions at unusually early and late hours. However, this time I had an opening in my schedule that matched an early morning fitness boot camp. It felt great to be coached through a workout for the first time in many years.

10 years ago while I was power lifting competitively I had the pleasure of training with both a coach and teammates. I later coached power lifting athletes more than twice my age. At the same time I owned a private fitness facility and mentored a team of eight personal trainers. Together we conducted 150 private fitness appointments and classes each week.

At monthly team meetings, in addition to discussing necessary day-to-day business like many companies, each trainer shared a list of business and personal goals; what was added to the list or accomplished since our last meeting. A common goal and requirement for employment was maintaining current credentials with continuing education; in other words learning something new. Since my personal trainers were well educated I knew they had the knowledge to bring the best fitness coaching to their clients. Beyond that, sharing our goals with each other helped us to get to know each other better and encourage each other. We made direct positive impact on each other’s success; such as client referrals or team training clients during alternating vacation schedules.

One of my mentors said, “Everyone needs a coach.” I changed it to “Everyone needs a coach sometimes,” because I believe we can each be self-motivated enough to make some improvements on our own. However, there is definitely a place for seeking out a professional to move beyond our own resources and limitations, and learning something new is often a requirement to reach high levels of performance. It is important to choose coaches carefully. Both dive instructors and fitness professionals need to carry current and proper credentials. Divers will often find the most committed and successful instructors are those with regular and consistent continuing education. Good instructors and coaches will respect that an individual is reaching out to them for their expertise and inspiration, and be certain not to exploit or take negative advantage of their position in the relationship. Good students will bring their personal best all the time – physically, mentally and emotionally.

In the book “Awakening the Olympian Within” compiled by Jim Naber, Olympic Gold Medalist Nancy Hogshead, the most decorated swimmer in the 1984 Olympics in Los Angeles, wrote, “Success is a Learned Skill.” About Being Coachable, she said:

“Everyone talks about finding a mentor or mentoring others, but few talk about the skills needed to be mentorable, to be coachable. I define being coachable as giving another person permission to demand the very best of you. I don’t mean following someone blindly, ignoring your ideas or principles. I’m talking about having a goal big enough that you’re willing to step outside your comfort zone – in your relationships with others – and to allow someone else to contribute.”

Fitness boot camp was a lot of fun and I am going again tomorrow…and I did learn something new.

The Pomegranate Gift

A Story For the Heart

Last week a friend of mine who is recovering from a heart valve repair received a bottle of pomegranate juice as a get well gift. The pomegranate gift was perfect. Pomegranates contain polyphenols with powerful antioxidant properties. The touted health benefits of pomegranate juice are sometimes loosely and broadly stated, so I wanted to bring sound information and studies that are particularly interesting for divers.

Here is a link to nearly 300 studies found at the National Institutes of Health, National Center for Biotechnology Information.

The American Heart Association shares a potential warning about drug interactions with pomegranate juice similar to grapefruit juice, and recipes for women’s heart health mentioning the benefits of folic acid and vitamin C found in pomegranate juice.  Studies and discussions center around the heart, blood, cancers and diabetes.  One major conclusion is that there doesn’t seem to be any adverse effects of pomegranate juice consumption regardless of whether studies prove the benefits.

There does seem to be a clear indication that more research will add to the existing data showing benefits of consuming pomegranate juice as part of a healthy diet may include helping to reduce blood pressure, improve cholesterol, slow prostate cancer and limit atherosclerosis.  Remember, antioxidants help counteract free radicals (damaged cells that can lead to disease).

There’s more to the story . . .

Heart Health benefits of Pomegranate Juice My friend’s surgery was two-weeks ago and he is already walking three miles a day and has returned to half days at work. The surgery was performed by Dr. James Hemp, Chief Surgeon at Scripps Mercy Hospital in San Diego with the assistance of da Vinci robotics. A few years ago, one of my fitness clients also received the same surgery by Dr. Hemp. Having personally observed the results and recovery from this less invasive method of heart surgery, I encourage anyone anticipating surgery to research the da Vinci method to see if it is an appropriate option.  I have also had an opportunity to meet Dr. Hemp.  He is a highly respected, trusted surgeon, and a remarkable individual. Dr. Hemp and his team at Scripps have made an amazing contribution to the quality of life for both my friend and my client.
