While ab stimulators can force the abdominal muscles to lớn contract, they will not burn fat or cause significant weight loss.

Very little retìm kiếm has assessed how well ab stimulators work for toning muscles. We look at the evidence lớn tư vấn their use & explain alternative ways lớn strengthen the abdominal muscles.

Doctors & physical therapists have used electrical devices khổng lồ treat injured or paralyzed muscles for decades. Functional electrical stimulation (FES) uses an electrical pulse to force muscles to lớn contract. By doing this, it prevents muscle wasting và encourages blood flow lớn the muscles. It may also help repair damage.

More recently, ab stimulator manufacturers have begun selling these devices to lớn the general public. Some companies clayên that their devices tư vấn weight loss or build strong ab muscles without requiring exercise. However, there is no evidence that a muscle stimulator can substantially change a person’s body toàn thân.

The Food and Drug Administration (FDA) regulate these devices as medical devices, but some manufacturers — especially outside the United States — now sell unregulated devices.

Is it effective? 

FES works well as a physical therapy tool for people with serious muscle injuries.

For example, a doctor might recommover ab stimulation following a spinal cord injury lớn restore some abdominal muscle function và help a person breathe on their own. A năm nhâm thìn nhận xét of 14 previous studies found that, following FES, people with spinal cord injuries were better able lớn breathe on their own than those acting as controls.

There is less evidence that abdominal stimulators can train the abs in people seeking increased muscle strength, better posture, or a slimmer waistline. The limited retìm kiếm that has looked at these devices has reported very small changes that were insufficient to lớn change a person’s appearance significantly.

For example, a 2005 study followed 24 adults who did no exercise but used ab stimulators 5 days per week for 8 weeks. Each session lasted for 20–40 minutes. The researchers compared them with 16 adults who neither used ab stimulators nor did any ab exercises for the study period.

The study group had a 58% increase in ab strength, which the team measured using an isokinetic dynamometer. A curl-up kiểm tra showed that these individuals had a 100% increase in abdominal endurance, compared with a 28% increase in the control group.

The study group also had an average 3.5-centimeter (1.4-inch) decrease in waist circumference. All 24 people in the stimulation group said that their abs were more toned, and 54% reported that their posture had improved. The control group did not report similar outcomes và had no reduction in waist circumference.

These findings suggest that ab stimulators might improve sầu strength và posture while offering a very small change in waist kích cỡ. However, the study was very small, & researchers have sầu not replicated it. Therefore, it is impossible to lớn draw strong scientific conclusions about the effectiveness of ab stimulators.

A more recent study involving trained athletes found that 12 weeks of FES did not increase the form size of the abdominal muscles.

Although the evidence that ab stimulators work well for toning the muscles is weak, FDA-regulated stimulators are safe khổng lồ try.

Ab stimulators cannot burn fat. To burn fat, a person must create a calorie deficit, using more calories through exercise & movement than they eat each day. Even when ab stimulators do slightly strengthen muscles, therefore, a person will not notice a difference in their appearance if they are not also burning fat.

Some of the most popular ab stimulators are available online, with reviewers promising rapid results and significant changes in body toàn thân shape.

However, many of these review are giả. People should be especially mindful of short đánh giá, Reviews that make extreme claims, và reviewers who have not reviewed other products or leave five sầu stars for every sản phẩm. Fakespot and ReviewMeta are examples of sites that can help with detecting giả online review.

Most ab stimulators are adhesive sầu pieces of cloth that a person sticks to lớn their abs. Each portion of the cloth delivers an electric current khổng lồ the abdominal muscles, causing contractions that a person might not even feel.

Some stimulators are belts that require no adhesive sầu và wrap around the body toàn thân. These may stimulate only the abs, or they might also stimulate the baông xã.

A few stimulators offer apps lớn traông chồng progress, and most allow a user khổng lồ adjust the intensity of muscle contractions. The stimulator should not hurt, sting, or burn, & it should not cause muscle spasms.
