Speed and Agility: July Fitness Theme

Friday, July 1st, 2011

Monthly Theme:  Speed

July’s theme is speed and agility.  Almost all of us need speed and agility whether we realize it or not; even the elderly sometimes need to move quickly in order to stop themselves from falling or to catch something quickly.  Most sports require significant amounts of quickness in order to execute perfect shots, run really fast, change direction, dodge another person, or to maintain their balance.  Strength training allows an athlete to develop more muscle mass and create more force in the muscle, but speed and agility training helps to make that force into something an athlete can use to do their sport better.   “Train slow, be slow” is a good catch phrase to keep in mind for training, and that is why it is good to stress quickness at certain times of the year.

So how often should people train for speed and agility, and what types of exercises should you choose?  At minimum, most people would benefit from doing basic footwork agility once per week.  This could be as simple as stepping forwards and backwards over a single line as quickly as you can for 20 seconds X 3 sets.   The type of exercises you choose should vary based on the demands of your lifestyle and sports that you choose.   Some athletes will have 3-4 workouts per week that are dedicated to combinations of jumps and sprinting, while some people may only need to do a couple of agility exercises in their garage once per week.  Some speed/ agility drills can also put significant loads on the joints of the body, and so anyone who has arthritis or any other medical problem that could be worsened by exercise should be careful what exercises they choose.

The following is a list of various speed and agility drills that you can try.  Be careful to choose only exercises that are similar to exercises that you have done in the last 2 months – if they are new to you, you should do the minimum amounts of sets and make sure your quality is good before progressing toward to going 100% with your efforts.  Start with the low impact ones and slowly progress (over 3-6 months) toward the higher impact ones.

Sample Speed/ Agility Drills

Perform between 3-6 of the following drills in any given workout, for 1-3 sets per exercise.  Keep the time for each set to less than 20 seconds.  You should stop before the body starts to feel fatigued, and always allow lots of rest (1-2 minutes) between sets if you want to make the most improvement possible.

Fish Oil Prevents Aging

A study from the American Journal of Medicine demostrates an association between blood levels of Omega 3 fatty acids and a lower rate of DNA ‘wear and tear’.

Antidepressants work…if you really need them

A new meta-analysis was published in the Journal of the American Medical Association that suggests that antidepressants might only be effect for moderate to severe depression.  The study used only studies that used the Hamilton rating system to determine depression severity.

Platelet Rich Plasma Therapy May Not Work

A popular treatment for tendon injuries is still under question as to whether it works or not.  This latest study compared it to salt water injections – another study that suggests that the injects alone may be what is therapeutic, not the actual agent injected.

MMR Vaccine and Autism – The Lancet takes back the 12 year old paper

The Lancet medical journal had finally taken back its 12-year old paper that suggested links between the MMR vaccine and Autism.  The backlash to this article is significant, with authorities considering legal action against the physician responsible for the article.  The avoidance of the MMR vaccine due to fears of Autism has led to an increased incidence of measles infections worldwide.

Is the Jury Still Out on a Low Sodium Diet?

This NYT article talks about the hot debate over whether ‘anti-salt’ campaigns should be increased or decreased.  Too much salt is probably bad, but too little salt is also bad.  For now, keep checking your blood pressure from time to time and watch your salt intake if your numbers start to climb.

Fitter Students do Better on Exams

A group of researchers showed that students who had better cardiorespiratory fitness also did better academically.  Reportedly, more studies need to be done to prove a causal relationship before schools start to bring back physical education into their curriculum.  In the meantime, more than 1/3 of our children are overweight or obese…but, I guess we need more proof!

Stress EKG’s Help, but Who Wants to Pay for it?

Electrocardiograms can save lives in young athletes by alerting them that they may have an unknown heart condition.  Because these heart conditions are fairly rare, screening is not advocated because it would not be cost effective.  If you perform regular, intense physical activity, the test deserves serious consideration.

Interesting Research Ties Appetite to Your Gut Bacteria

Altering the bacteria in your intestines may lead to better digestion, lower appetite, and weight loss…some day.

A Good Review of Reasons to Exercise

Jane Brody of the NYT reviews the scientific evidence that supports the use of exercise for good health.

Vit D – More Evidence

Every month or two another study comes out to reinforce the importance of having adequate Vit D.  This article highlights the mechanisms through which Vit D may be helping to prevent cancer and autoimmune disease.

PSA – Should it be Used to Screen for Prostate Cancer?

The PSA test is costing the US billions of dollars per year with limited success in fighting prostate cancer.  The author of this NYT article does a good job at reviewing the evidence.   Click here to view some of the follow up from this article.

Breast Cancer Screening Works – Rarely

“Evidence now suggests that for every 2,000 women who are screened over 10 years, only one stands to have her life saved by the mammogram program, he said, whereas the risk of getting an unnecessary breast cancer diagnosis is 10 times that”.

Following the adjustments to the recommended screening age for mammography in the US (from 40-50 years of age), some are questioning the use of mammography altogether.

Statins Become Preventive Medicine

The FDA has approved the use of Crestor, a medication used to lower cholesterol, for preventive medicine uses.  It has been long been known that statins can act like anti-inflammatories in the body with can theoretically help to prevent a heart attack or a stroke.  Crestor’s main mechanism of action is to block the body’s production of cholesterol, an essential lipid that the body uses to make cell membranes, hormones, and other things in the body.  Time will tell if this drug will do more harm than good in patients with normal cholesterol levels.

Weak Preventive Medical Screening Policies Lead to Debate

Why is there so much debate about cancer screening tests like the PSA and Mammogram?  Because they don’t seem to be very effective.  So what’s the solution?

Hormone Therapy Protects Against Colon Cancer

Another study confirms that hormone replacement therapies can protect against colon cancer.  Long term users experience over a 50% reduction in cancer rates.

Diet Prevents 40% of Alzheimer’s Cases

A diet rich in fruits and vegetables, olive oil, nuts, seeds and fish is shown to lead to less cases of Alzheimer’s disease.

Processed Meats, not Red Meats are Associated with Cancer

A new harvard study had found an association between eating processed and developing cancer.  The same study was not able to show a significant association between those that ate unprocessed meats like beef, pork or lamb and those that developed cancer.
