Abstract (provisional)

Background

To determine the effects of supplemental fish oil (FO) on resting metabolic rate (RMR), body composition, and cortisol production in healthy adults.

Method

S: A total of 44 men and women (34+13y, mean+SD) participated in the study. All testing was performed first thing in the morning following an overnight fast. Baseline measurements of RMR were measured using indirect calorimetry using a facemask, and body composition was measured using air displacement plethysmography. Saliva was collected via passive drool and analyzed for cortisol concentration using ELISA. Following baseline testing, subjects were randomly assigned in a double blind manner to one of two groups: 4g/d of Safflower Oil (SO); or 4g/d of FO supplying 1,600mg/d eicosapentaenoic acid (EPA) and 800mg/d docosahexaenoic acid (DHA). All tests were repeated following 6wk of treatment. Pre to post differences were analyzed using a treatment X time repeated measures ANOVA, and correlations were analyzed using Pearson's r.

Results

Compared to the SO group, there was a significant increase in fat free mass following treatment with FO (FO= +0.5 +/- 0.5kg, SO= -0.1 +/- 1.2kg, p=0.03), a significant reduction in fat mass (FO= -0.5 +/- 1.3kg, SO= +0.2 +/- 1.2kg, p=0.04). and a tendency for a decrease in body fat percentage (FO= -0.4 +/- 1.3% body fat, SO= +0. 3 +/- 1.5% body fat, p=0.08). No significant differences were observed for body mass (FO= 0.0 +/- 0.9kg, SO= +0.2 +/- 0.8kg), RMR (FO= +17 +/- 260kcal, SO= -62 +/- 184kcal) or respiratory exchange ratio (FO= -0.02 +/- 0.09, SO= +0.02 +/- 0.05). There was a tendency for salivary cortisol to decrease in the FO group (FO= -0.064 +/- 0.142ug/dL, SO= +0.016 +/- 0.272ug/dL, p=0.11). There was a significant correlation in the FO group between change in cortisol and change in fat free mass (r = -0.504, p=0.02) and fat mass (r = 0.661, p=0.001).

CONCLUSION: 6wk of supplementation with FO significantly increased lean mass and decreased fat mass. These changes were significantly correlated with a reduction in salivary cortisol following FO treatment.

Goooooooo for it! Emailed to me by a great triathlon coach Mr. Kypros Nicolaou. I'm out......

Are you one of those trendy Pilates person?

Recently, I came across so many individuals that are crazy about Pilates. They consider it the best exercise ever, and especially women love it. Hhhhhmmm.........is Pilates a complete training philosophy for you? What is Pilates ?...do you really know or you just join cause you want to look cool.

Personally, people's ignorance on the topic is one thing that drives me nuts. Here are my pros and cons on Pilates philosophy.

Pros:

1. It's a form of a less strenuous activity...which is great....targeting mainly the core.

On the other hand, the Cons:

1. Gooofyyy Instructors. These are people that do a 2 weeks certification and they think they are the experts on the topic. They literally do not know anything else. They just know few exercises. They do not have a justification for what is going on and they are the ones that most of the people out there, especially in Cyprus that trust and they consider it as 'value for money'.
   
2. No specificity what so ever. Is there a connection between Pilates and a sport or an activity that you are part of? If you have a back pain...maybe is the right form of exercise for you, but does the trainer understands exactly what is the problem and what he can do to help.
3. Forgotten other important elements of training such as power, cardiovascular endurance, and joint stability and mobility.
4. Not such a variety of equipment used. Challenging the body with different equipment can keep the workouts more fun and surely more beneficial towards your fitness goals.
   
5. Not much resistance used. The resistance that is use is not that much sooooooooo that equals with a lower metabolism and not an effective method if you are goal is to loss excess fat. This goes out to all the women out there who think that weights are bad for them.
6. Low intensity. Have you ever seen someone doing a pilates class and be out of breath or depict that pilates is a tough training regime? Easy workouts are not very beneficial for you health, performance and great results, so accept it and move on. Of course you need easy workouts, but in the long run tough workouts to the point of your goals are crucial.

Finally , I believe that there are some great Pilates instructors out there that know really the WHY of everything. If you want to experience a more complete training philosophy just come by the 3 D studio anytime. The question remains...Why do you use Pilates for? I'm out......
