Does ‘Carb-Loading’ Improve Athletic Performance?

  For generations, endurance athletes have practiced ‘carb-loading’, consuming large amounts of carbohydrates the night before the competition. Studies have found several different carb loading strategies can give athletes a competitive edge.

  During digestion carbohydrates are rapidly turned into glucose, a sugar that is the body’s primary and most immediate energy source. Excess glucose is then stored in the liver and muscles as glycogen. About four hours after a meal, the glycogen in the liver begins to break down and supply the body with glucose, but the glycogen in the muscle is reserved almost exclusively for muscle activity. By eating a high carbohydrate meal the night before a competition, athletes maximize the glycogen stores in their muscles, ensuring that the muscles will have enough glucose for strenuous activity.

  Studies have shown carb-loaded athletes perform better and their muscles do not fatigue as easily. However it is important to watch your calories. Excess calories of any kind have been shown to impair athletic performance. -Sean Kenniff, MD

The Ten Most Effective Abdominal Exercises: #3 The Exercise Ball Crunch

  If you’re trying to tone your tummy, and want that washboard look, try these top ten abdominal exercises. Using electromyography (EMG) Dr. Peter Francis and his team from the Biomechanics Lab at San Diego State University measured abdominal muscle activity, and put some of the most commonly performed exercises to the test. They ranked them from most effective to least effective. The study was sanctioned by the American Council on Exercise (ACE). 

#3 The Exercise Ball Crunch 

  Dr. Francis found the most effective abdominal exercises combined continuous abdominal contraction and rotation of the torso. Overall the Bicycle Maneuver ranked #1 and the Captain’s Chair ranked #2 (see below). The Exercise Ball Crunch was the third most effective exercise for working the abs (it also finished #6 for working the oblique muscles). Here’s how to perform the Exercise Ball Crunch properly according to the ACE.

1. Sit on the ball with your feet flat on the floor.

2. Lie back on the ball until your thighs and torso are parallel to the floor.

3. Cross your arms over your chest, or place them lightly behind your head. Do not pull on your neck.

4. Contract your abdominals raising your torso no more than 45 degrees.

5. Move your feet closer together to work your obliques.

6. Repeat sets of 12-20 repetitions.

The Ten Most Effective Ab Exercises: #2 The Captain’s Chair

  If you want washboard abs this summer, you might want to try the ten exercises most likely to give them to you. Dr. Peter Francis from the Biomechanics Lab at San Diego State University measured abdominal muscle activity with electromyography (EMG) devices, and put some of the most commonly performed exercises to the test, ranking them from most effective to least effective. The study was sanctioned by the American Council on Exercise (ACE).

#2 The Captain’s Chair

  Dr. Francis found the most effective abdominal exercises combined continuous abdominal contraction and rotation of the torso. Overall the Bicycle Maneuver ranked #1 (see below), but the ‘Captain’s Chair’ finished a close second and it strengthened both the abdominal and oblique muscles the best. Here’s how to perform the exercise properly according to the ACE.

     1. Stabilize your upper body by gripping hand holds.

     2. Lightly press your back against the back pad.

     3. Slowly lift your knees to your chest, then return legs to starting.

     4. The motion should be controlled and deliberate, not fast or jerking.
