Mark Your Calendars!
NYC Fitness Conference:
September 17, 18 & 19, 2004
Earn up to 2.0 CECs / 20.0 CEU’s in one weekend!

It’s that time of year again…our annual New York City Fitness Conference, bigger and better than ever!

Since so many Certifying Organizations are now requiring you to earn additional CE’s for renewal, we are pleased to announce that we are planning to add classes on Friday evening, September 17. By attending our program Friday night, Saturday and Sunday you can earn up to 2.0 CEC’s and/or 20 CEU’s of credit in the same weekend. Schedule conflicts? You can just take 1 or 2 workshops if you can’t commit to the whole weekend.

This year we’ll be offering over 30 separate programs, including some of our hottest new courses such as:

• Cardio on the Ball
• Intro to Yoga
• Strength Ball Training
• Double Tube Workout
• Many more

This year’s Conference will be held at the Marriott/East at Lexington and 49 Street. The complete NYC schedule will be posted on our web site July 15, but until then, don’t make any other plans for September 17-18-19.

Training the
Shoulder Depressors
Benefits Clients with
Impingement Syndrome

Strengthening of the shoulder depressors - the rotator cuff - is an important component in the treatment of impingement syndrome. The purpose of this study was to analyze the influence of adduction and abduction forces on the subacromial space. The study evaluated healthy volunteers using various arm positions. Open MRI images were taken with the shoulder at 30°, 60°, 90°, 120°, and 150° of arm elevation during isometric adduction and abduction. The distances in the acromio-humeral and claviculo-humeral spaces were evaluated.

During elevation of the arm, subacromial space width was reduced significantly; abduction decreased the space even more. Interestingly, adduction of the arm led to a significant increase of the acromio-humeral distance in all arm positions.

This study shows for the first time that adduction muscle forces lead to a significant increase of the subacromial space compared to abduction forces. This technique may, in the future, be used to more efficiently and comfortably train clients with impingement syndrome of the shoulder.

Commentary: This study was done with healthy subjects. The results support the benefits of training the rotator cuff and the larger depressors - pectoralis major, latissimus dorsi, and teres major - in the treatment of impingement. One suggested exercise is the seated press down: it keeps the arm in an adducted position while training the depressors/adductors.

Interval Training Slows
Heart Rate Decline
in Older Adults

Heart rate variability is considered to be a reflection of the activity of the autonomic nervous system, and it reportedly declines with aging. This decline has been associated with increased cardiovascular risk and mortality in older adults. The purpose of this study was to compare heart rate variability in older subjects who were sedentary to those who participated in active sports.

The results? Heart rate variability was significantly higher for the sportive adults than for the sedentary adults. It was concluded that since many sporting activities are associated with bursts of high intensity intervals that this type of activity maintains heart rate variability better than routine ADLs.

Commentary: While heart rate variability is beyond the Fitness Professional’s capacity to evaluate, these results suggests yet another physiological benefit to conditioning programs that require bursts of high-intensity efforts. Resistance training and intervals come to mind.
