New study: Effects of Energy Drinks

There is a new study on the effects of energy drinks and the conclusion is not good news. Peveler, WW, Sanders, GJ, Marczinski, CA, and Holmer, B. have been published their study to determine the effect of 3 different energy drinks on cardiovascular and performance measures. It is important to recognize the difference between these new products and traditional soft drinks such as coffee, tea, sports drinks (such as Gatorade), sodas, juices, or flavored water.

“Fifteen recreational runners completed 5 trials. The first trial consisted of a graded exercise protocol. The 4 remaining trials consisted of 15-minute economy trials at a treadmill. An hour before subjects ingested 1 of the 3 energy drinks or a placebo. HR, BP, VO2, and rating of perceived exertion (RPE) were recorded during the 15-minute trial.

Fifteen-minute systolic BP readings were significantly lower in the placebo trials in relation to the 3 energy drink trials.

  • There were no significant differences in diastolic BP and HR.
  • There were no significant differences found in VO2 or RPE measures.
  • The findings show no performance benefits under the conditions of this study.
  • However, there does appear to be a significant increase in systolic BP.”

Translated, performance is not a reason to drink energy drinks. Caffeine and taurine will not enhance your performance. Your heart will beat faster and this may induce you to think you´re performing better. False impression.

Actually, if you take a look at a previous study (John P. Higgins, Santi Yarlagadda, and Benjamin Yang. Cardiovascular Complications of Energy Drinks), there is no reason at all to drink these beverages. This study concludes that energy drinks are “associated with complications not only patients with underlying cardiovascular conditions but also in young people.”

It would be a disaster if doing sports, trying to perform better, you get serious health issues because of a bad choice. Choose traditional: water, juices, sports drinks, and enjoy the process of a healthy living.

  2. Ever since they came out I’ve always gotten a bad vibe from them, like something just isn’t right. I used to partake in a green Monster once a month or so but it’s been years.

    I do take issue with the notion that caffeine doesn’t improve performance though. Science has clearly shown it has. Taurine may not, and energy drinks are obviously crap, but caffeine was made in Heaven. By angels.

    1. I gave Red Bull a chance at first, but my stomach couldn´t handle it and I didn´t like its taste either. So my romance with energy drinks ended pretty soon :)
      Let me say that the study finds the mix caffeine-taurine useless for performance. It doesn´t say anything about taking one or another separately.
      Taurine is an antioxidant involved in the transmission of nerve impulse, the processes of the immune system, the inhibition of the oxidation of fats and is a key element in sugar metabolism.
      Caffeine also looks esential, specially in the mornings :D
      Big hugs!

Lower Back

The Erector Spinae is not just one muscle, but a bundle of muscles and tendons. Paired, they run more or less vertically. It extends throughout the lumbar, thoracic and cervical regions, and lies in the groove to the side of the vertebral column.

Latissimus Dorsi

The latissimus dorsi is the larger, flat, dorsolateral muscle on the trunk, posterior to the arm, and partly covered by the trapezius on its median dorsal region.

Deltoids

The Deltoid muscle is the muscle forming the rounded contour of the shoulder. It is divided into three portions, anterior, lateral and posterior, with the fibers having different roles due to their orientation.

Infraspinatus

The Infraspinatus muscle is one of the four rotator cuff muscles crossing the shoulder joint and is commonly injured. It is the main external rotator of the shoulder joint.

Biceps

The Biceps brachii is  actually two separate bundles of muscles (heads). The two heads of the Biceps vary in length and as a result, are called the Short and the Long Biceps heads.

Triceps

The Triceps Brachii muscles  have three muscle heads: Lateral, Medial and Long head. Primarily responsible for the extension of the elbow joint. The lateral head is used for movements requiring occasional high-intensity force, while the medial fascicle enables more precise, low-force movements.

Forearm
(Anterior muscles)

The Pronator teres pronates the forearm, turning the hand posteriorly. If the elbow is flexed to a right angle, then pronator teres will turn the hand so that the palm faces inferiorly. It is assisted in this action by pronator quadratus.

Forearm
(Posterior muscles)

The Extensor Digitorum muscle helps in the movements of the wrists and the elbows. It extends the phalanges, then the wrist, and finally the elbow. It acts principally on the proximal phalanges. It tends to separate the fingers as it extends them.

Pecs

The pectoralis major makes up the bulk of the chest muscles in the male and lies under the breast in the female.

The pectoralis minor is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major. 

Abs

The Rectus Abdominis is the most superficial of the abdominal muscles. It is this muscle which forms the six-pack shape! It is a paired muscle running vertically on each side of the anterior wall of the abdomen. There are two parallel muscles, separated by a midline band of connective tissue called the linea alba.

Obliques

The External Oblique is situated on the lateral and anterior parts of the abdomen. It is broad, thin, and irregularly quadrilateral. It is the largest and the most superficial (outermost) of the three flat muscles of the lateral anterior abdomen. 

Glutes

The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur. The functions of the muscles include extension, abduction, external rotation, and internal rotation of the hip joint.

Quadriceps

The Quadriceps Femoris is the knee extensor muscle.  As a group, the quadriceps femoris is crucial in walking, running, jumping and squatting. It´s subdivided into four separate “heads”.

Hamstrings

A hamstring is any one of the three posterior thigh muscles in between the hip and the knee (from medial to lateral: semimembranosus, semitendinosus and biceps femoris). The hamstrings are quite susceptible to injury.

Lower Leg

The gastrocnemius and the soleus form what we know as calf. They are involved in activities such as walking, running, jumping…

Trapezius

The trapezius is a broad, flat and triangular muscle. The muscles on each side form a trapezoid shape. It is the most superficial of all the back muscles.
