Kegel exercise

Kegel exercise is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kegel exercise rather than just read about it. In short: Kegel exercise, also known as pelvic floor exercise, involves repeatedly contracting and relaxing the muscles that form part of the pelvic floor, also sometimes colloquially referred to as the "Kegel muscles". The exercise can be performed many times a day, for several minutes at a time, but takes one to three months to begin to have an effect.

Key takeaways

  • Kegel exercise belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Kegel exercise to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Kegel exercise from memory before moving on to harder problems.

Reference excerpt

Kegel exercise, also known as pelvic floor exercise, involves repeatedly contracting and relaxing the muscles that form part of the pelvic floor, also sometimes colloquially referred to as the "Kegel muscles". The exercise can be performed many times a day, for several minutes at a time, but takes one to three months to begin to have an effect. Kegel exercises aim to strengthen the pelvic floor muscles. These muscles have many functions within the human body. In women, they are responsible for holding up the bladder, preventing urinary stress incontinence (especially after childbirth), vaginal and uterine prolapse. In men, these muscles are responsible for urinary continence, fecal continence, and ejaculation. Several tools exist to help with these exercises, although various studies debate the relative effectiveness of different tools versus traditional exercises. The American gynecologist Arnold Kegel published a description of such exercises in 1948, but they had previously been published in 1936 by a woman, Margaret Morris, who was given little credit at the time.

Mechanism of action Kegel exercises aim to improve muscle tone by strengthening the pubococcygeus muscles of the pelvic floor. Kegel exercises are commonly prescribed for pregnant women to prepare the pelvic floor for physiological stresses of the later stages of pregnancy and childbirth. Various advisors recommend Kegel exercises for treating vaginal prolapse and preventing uterine prolapse in women and for treating prostate pain and swelling resulting from benign prostatic hyperplasia (BPH) and prostatitis in men. Kegel exercises may have benefits in treating urinary incontinence in both men and women. Kegel exercises may also increase sexual gratification, allowing women to complete pompoir and aiding men in reducing premature ejaculation. The many actions performed by Kegel muscles include holding in urine and avoiding defecation. Reproducing this type of muscle action can strengthen the Kegel muscles. The action of slowing or stopping the flow of urine may be used as a test of the correct pelvic-floor exercise technique. The components of levator ani (the pelvic diaphragm), namely pubococcygeus, puborectalis, and iliococcygeus, contract and relax as one muscle. Hence pelvic-floor exercises involve the entire levator ani rather than pubococcygeus alone. Pelvic floor exercises may help in cases of fecal incontinence and pelvic organ prolapse, such as rectal prolapse.

Health effects

Women Factors such as pregnancy, childbirth, aging, and being overweight often weaken the pelvic muscles. This can be assessed by either digital examination of vaginal pressure or using a Kegel perineometer. Kegel exercises are useful in regaining pelvic floor muscle strength in such cases. The symptoms of prolapse and its severity can be decreased with pelvic floor exercises. Effectiveness can be improved with feedback on how to do the exercises.

Men Kegel exercises can train the perineal muscles by increasing the oxygen supply and the strength of those muscles. The names of the perineal muscles are: ischiocavernosus (erection), bulbocavernosus (ejaculation), external sphincter of the anus, striated urethral sphincter, transverse perineal, levator of the prostate, and puborectalis. Premature ejaculation is defined as when male ejaculation occurs after less than one minute of penetration. The perineal muscles are involved in ejaculation when they are involuntarily contracted. The ischiocavernosus muscle is responsible for male erection, and the bulbocavernosus muscle is responsible for ejaculation. By actively contracting the perineal muscles with Kegel exercises regularly, strength and control of these muscles increase, possibly aiding in the avoidance of premature ejaculation.

Urinary incontinence Pelvic floor exercises (muscle training) can be included in conservative treatment approaches for women with urinary incontinence. There is tentative evidence that biofeedback may give added benefit when used with pelvic floor muscle training (PFMT). There is no clear evidence that teaching pelvic floor exercises alters the risk of stress urinary incontinence in men who develop this condition post prostatectomy. In pregnant women, antenatal PFMT probably helps prevent urinary incontinence during pregnancy and up to six months after giving birth, but for pregnant women who already have incontinence, it is not clear if antenatal PFMT helps to reduce symptoms.

Fecal incontinence In pregnancy, it is not yet clear if antenatal PFMT helps to prevent or treat fecal incontinence.

Pelvic toning devices Some devices, marketed to women, are for exercising the pelvic floor muscles and to improve the muscle tone of the pubococcygeal or vaginal muscle. As of 2013, there was no evidence that doing pelvic floor exercise with weights worked better than doing Kegel exercises without weights; there is greater risk with weights, because a foreign object is introduced into the vagina.

Marketing During the latter part of the 20th century, several medical and pseudo-medical devices were marketed to consumers as improving sexual performance or orgasms, increasing "energy", "balancing hormones", and as having other health or lifestyle benefits. There is no evidence for any of these claims, and many of them are pseudoscience.

Worked examples

Example 1 — a first encounter with Kegel exercise

Start with the simplest possible case. Write down what Kegel exercise claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kegel exercise before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kegel exercise ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kegel exercise

In research
Kegel exercise appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Kegel exercise in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Kegel exercise is common in secondary-school and first-year university syllabi. It links to neighbouring topics Health issues in pregnancy, Obstetrical and gynaecological procedures, Physical exercise, so understanding it makes those chapters shorter.
In everyday life
Look for Kegel exercise outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Kegel exercise matter?

How should I study Kegel exercise?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
