Electro Cut Your Body Fat Study Shows 5 6 cm and 4 9 Reduction in Waist Body Fat in Young Women in 6 Weeks

No sweat, just some wires? Study shows: It does not take much effort to lose belly fat.

Liposuction is an invasive procedure that is not without risk. Against that background its no wonder that people are marketing alternative methods like high-frequency current therapy as allegedly safe go-to methods to rid yourself of unwanted body fat. The question is: Do these currents actually help you to lose body fat? That is: Can electrocuting your belly "electro-cut" significant amounts of body fat? Practitioners who use this technology will say "yes". From a scientific standpoint, though, the question is difficult to answer, because the use of high-frequency current therapy has been given little attention in the scientific community.

As Kim et al. point out in a recent paper in the J. Phys. Ther. Sci., some previous studies have failed to provide evidence for the effectiveness of high-frequency current therapy in women with obesity, whereas more recent studies have indicated that a high-frequency current therapy decreases female abdominal obesity (Kang. 2005; Han. 2010). Accordingly, their latest study aimed to determine whether high-frequency current therapy can be effectively used to reduce female abdominal obesity.

To this ends, the researchers recruited twenty-two female volunteers who were randomly allocated to either the experimental group (EG) (n = 12; age, 21.17 ± 0.72 years; weight, 63.17 ± 7.91 kg; height, 159.63 ± 4.56 cm) or the control group (CG) (n = 10; age, 21.10 ± 0.74 years; weight, 68.79 ± 11.73 kg; height, 161.69 ± 5.25 cm). Inclusion criteria were as follows:

• a body mass index (BMI) of ≥23 kg/m2 and a waist-hip circumference ratio of  ≥ 0.8013
• no past or present neurological, musculoskeletal, or cardiopulmonary disorders that would have affected health condition;
• no smoking and drinking habits; and
• no psychological problems.

Futhermore, pregnant women were excluded as well. The subjects of both groups were asked to keep a regular dietary habit during the experimental process. A nutritionist drew up a diet plan of 2,000 to 2,500 kcal/day across 3 meals (8 a.m., 1 p.m., and 6 p.m.) for the 6-week intervention. In addition, subjects were asked to avoid extra activities and exercises beyond daily routine activities.

Figure 1. Changes in BMI, waist circumference, subcutaneous body fat and total body fat (%) after 18 sessions of high-frequency current therapy in Korean women (Kim. 2015).

Only the subjects in the EG group were subjected to high-frequency current therapy, with a frequency of 0.5 Mhz. The treatments were performed exclusively on the abdominal region while subjects were supine using specific equipment (CWM-9200; Chungwoo Medical, Seoul, South Korea) for 60 minutes, 3 times per week, for 6 weeks (a total of 18 sessions).

"High-frequency current therapy was performed in 2 phases: 2 sets of 15-minute applications of capacitive electric transfer (CET) and resistive electric transfer (RET) with the pulsed current option (current conduction time, 0.7 seconds; rest interval, 0.3 seconds) for the fist 3 weeks, followed by a 30-minute application of the CET and RET modes with continuous current conduction in the final 3 weeks. The intensity was individualized within a range of 6–7 mA to comfortably adjust the heating sensation during the intervention. An insulated electrode and a stainless steel electrode (8 cm in diameter) were used for the CET and RET modes, respectively. Conductive gel (Body Rubbing Cream; SA’COS, Incheon, South Korea) was used to facilitate skin moisture and current conduction, and high frequency current therapy was delivered by making circular motions of the electrode over the abdominal region at a moving speed of 5 cm/s, avoiding focused pressure on therapeutic areas" (Kim. 2015)

The comparison of the pre- vs. post-data showed here significant main effects of time with respect to waist circumference, abdominal obesity, subcutaneous fat mass, and body fat percentage, which differed significantly between the groups (see Figure 1), "suggesting the effects of high-frequency current therapy in decreasing obesity" (Kim. 2015).

Bottom line: I must say that I am impressed. I havent been there to control whether the scientists cheated, but considering the fact that the control group received the same controlled diet as the women in the experimental group, the loss of body fat and the reduction in waist circumference that was achieved within only 6 weeks in young women is impressive.

In the end, the mechanism of action is simple and is believed to rely mostly on the heat induced dilatation of subcutaneous vessels and the subsequent facilitation of the lipolytic process (Song. 2006). Which would also explain why the effect was highly localized and there were no significant inter-group difference with respect to the BMI of the women in the study at hand. A study that is yet limited by the low number of participants, a lack of safety data (no blood analyses, for example), the absence of measurements of the reductions in visceral fat and the lack of a rigid dietary and activity control as it would be possible in a metabolic chamber | Comment on Facebook!

Squat or Sled Study Compares Muscle Activation During Squatting Sled Pushing One For Quads One For Hams!

Original image from the publication.

As Meaghan E. Maddigan, Duane C. Button and David G. Behm from the Memorial University of Newfoundland rightly point out, "the back squat is a traditional resistance training exercise." (Maddigan. 2014).

The use of resisted sled exercises, on the other hand, is a relatively new phenomenon of which we dont even know yet how it compares to the classics.

Accordingly, Maddigan et al. set out to compare the muscle activation between squatting and sled pushing on the activity of leg and trunk muscles in ten healthy resistance-trained men in the context of a randomized crossover design study.

The study consisted of 2 preparation sessions and 2 testing sessions. Electromyographic (EMG) activity of the rectus femoris, biceps femoris, gastrocnemius, lower erector spinae, and the transversus abdominis/ internal obliques (TrA/IO) were monitored during a 20-step maximum push with the weighted sled apparatus and a 10 repetition maximum with a bilateral back squat.

All ten subjects were healthy resistance-trained men (age 24.6 years, mass 84.5 kg, height 178.3cm) who had at least 2 years of resistance training and squat experience and were also familiar with performing the sled exercises (however, the volume of squat experiences exceeded sled training volumes or training durations).

Figure 1: Average root mean square (RMS) EMG recorded in exercise phase 1, 2, and 3 (EMG signal was calculated over a 1-second segment of the concentric contraction phase of each step or repetition) from (A) rectus femoris, (B) biceps Femoris, (C) gastrocnemius, and (D) erector spinae during the concentric portion of the sled and squat exercises. Open circles represent the sled condition, whereas the filled squares represent the squat condition (Maddigan. 2014).

As you can see in Figure 1 there were nonsignificant trends for the rectus femoris ( p = 0.092: 8.6– 16.7%) and biceps femoris ( p = 0.09: 10.5–32.8%) to demonstrate higher activity with the sled and squat exercises, respectively. A result based on which you could conclude that

• squatting is better for the quads, while
• sled pushing is th better hamstring exercise

Maddigan et al. also observed main effects for condition with 61.2% greater gastrocnemius EMG with the sled exercise ( p = 0.01) and 74.5% greater erector spinae EMG activity with the squat (p = 0.002). For the transversus abdominis/ internal obliques, however, there were no significant differences between the exercises for the.

Bottom line: As the authors write in their conclusion, "the sled and squat exercises provided similar EMG activity for the quadriceps, hamstrings, and ransversus abdominis/ internal obliques." In that the squat may be more favorable for developing the quads, while the sled is the better hamstring activator and calf (gastrocnemius) builder.

As Maddigan et al. say, the decision which of the exercises is "best" for you will depend "on the movement-training specificity of the sport" you compete in. "[E]ither exercise may be used in a training program while acknowledging the differences in gastrocnemius and erector spinae activity." (Maddigan. 2014)

One question remains, though. Will the long-term adaptations reflect the different EMG-activation in the study at hand? To a certain extend this will probably be the case, whether and to which extent you would make better progress with one over the other exercise and if it makes sense to do both (maybe in an A-B workout style) will still have to be elucidated | Comment on Facebook!

Lack Of Protein Linked To Overeating And Obesity Study Finds

If youre struggling to lose weight or unable to suppress hunger pangs, it might be due to a lack of protein in your diet.

According to researchers at the University of Sydney, humans appetite for protein is so strong (and instinctive) that people will continue to eat until they get a sufficient amount of it.

As a result, authors conclude, this lack can cause over-eating and obesity.

"We found that regardless of your age or body mass index, your appetite for protein is so strong that you will keep eating until you get enough protein, which could mean eating much more than you should," said lead study author Dr Alison Gosby.



Protein is crucial to the bodys make-up. It helps build bones, muscles, skin, and blood, as well creating enzymes, hormones, and vitamins.

The food found in modern diets are tend to be higher in carbohydrates and fats with lower protein, say experts. This means that in order to reach optimum protein intake, people can find themselves over-eating carbs and fats.

Most people do eat the right amount of protein, the authors explain, just eat too much to get it.

"It has been shown numerous times that eating more protein is a good way to be satisfied from food," says Sam Feltham, HuffPost UK blogger, personal trainer and founder of Smash The Fat.

"Although natural fat is just if not more satisfying, but then there is a massive contradiction in conventional advice of limiting meat consumption, the best source for a full profile of proteins."

According to Sam, eating meat - particularly organ meat, "which has even more vitamins and minerals than regular muscle meat" - is the best way to increase protein intake.

Of course, it isnt the only way. Here are some great meat-free foods that are high in protein, to make sure you get enough of what you need.
