An exercise ball is a ball constructed of soft elastic, typically in 5 diameters of 10 cm increments, from {{cvt|35|to|95|cm|in}}, and filled with air. The air pressure is changed by removing a valve stem and either filling with air or letting the ball deflate. It is most often used in physical therapy, athletic training and exercise. It can also be used for weight training.
The ball is also known by various other names, for instance: balance ball, birth ball, sitball, body ball, fitness ball, gym ball, gymnastic ball, physio ball, pilates ball, Pezzi ball, stability ball, Swedish ball, Swiss ball, therapy ball, or yoga ball.
History
The physical object known as a "Swiss Ball" was developed in 1963 by Aquilino Cosani, an Italian plastics manufacturer. He developed a process for moulding large puncture-resistant plastic balls.{{cite book|last=Flett|first=Maureen|url=https://archive.org/details/swissballforstre0000flet/page/6/mode/2up|page=6|title=Swiss Ball: For Strength, Tone and Posture|publisher=Sterling Publishing|year=2003|isbn=1-85648-663-X|via=Internet Archive}} According to American physical therapist Joanne Posner-Mayer, the use of the exercise ball as a therapy tool probably begins with the Swiss pediatrician Dr. Elsbeth Köngan, an early advocate of the Bobath concept.{{cite book|url=https://books.google.com/books?id=lFsoDwAAQBAJ&pg=PT23|page=23|title=Pilates on the Ball: The World's Most Popular Workout Using the Exercise Ball|last=Craig|first=Colleen|publisher=Simon & Schuster|year=2001|isbn=9781594775932|via=Google Books}} Those balls, then known as "Pezzi balls", were first used in treatment programs for newborns and infants by Mary Quinton, a British physiotherapist working in Switzerland.
Later, Dr. Susanne Klein-Vogelbach, the director at the Physical Therapy School in Basel, Switzerland, integrated the use of ball exercise as physical therapy for neuro-developmental treatment. In 1985, she published a famous book “Ballgymnastik zur funktionellen Bewegungslehre” (“Ball Gymnastics for functional movement theory”), where she described several exercises with the ball. Klein-Vogelbach advocated the use of ball techniques to treat adults with orthopedic or medical problems.
In 1995, Joanne Posner-Mayer published a book "Swiss Ball Applications for Orthopedic and Sports Medicine" in the US. As American physical therapists began to use ball exercises, the term became common in the US.{{cite book

Benefits

A primary benefit of exercising with an exercise ball as opposed to exercising directly on a hard flat surface is that the body responds to the instability of the ball to remain balanced, engaging many more muscles (so-called “unstable training”).{{cite journal|url=http://www.ptjournal.org/cgi/content/full/80/6/564|title=Abdominal muscle response during curl-ups on both stable and labile surfaces|journal=Physical Therapy|last1=Vera-Garcia|first1=FJ|last2=Grenier|first2=SG|last3=McGill|first3=SM|year=2000|volume=80|issue=6|pages=564–569|doi=10.1093/ptj/80.6.564|pmid=10842409|archive-url=https://web.archive.org/web/20070927011806/http://www.ptjournal.org/cgi/content/full/80/6/564|archive-date=September 27, 2007|doi-access=free|url-access=subscription}}{{cite web|url=https://www.coachmag.co.uk/exercises/core-exercises/3710/the-benefits-of-gym-ball-exercises|title=Gym Ball Exercises That Everyone Should Be Doing|website=coachmag.co.uk|date=March 19, 2021|access-date=April 20, 2021}} Those muscles become stronger over time to keep balance. Some dumbbell exercises, such as dumbbell fly can be performed on a ball.{{cite web|url=https://dumbbellsreview.com/dumbbell-chest-exercises-without-bench/|title=Dumbbell Chest Exercises You Can Do Without a Bench|last=Demoss|first=Daniel|website=dumbbellsreview.com|date=April 2, 2021|access-date=April 20, 2021}} Ball exercises are popular among runners.{{cite journal|url=https://runningmagazine.ca/sections/training/exercise-ball-home-workout-for-runners/|title=Exercise ball home workout for runners|journal=Canadian Running|date=July 20, 2020|access-date=April 20, 2021}}
Most frequently, the core body muscles; the abdominal muscles and back muscles are the focus of exercise ball fitness programs.{{cite web|url=https://www.mayoclinic.org/healthy-lifestyle/fitness/multimedia/core-strength/sls-20076330|title=Fitness ball|publisher=Mayo Clinic|date=April 9, 2019|access-date=April 20, 2021}}
Using an unstable surface recruits more muscle units without increasing the total load. The greatest benefit of moving an exercise onto an unstable surface is achieving a greater activation of the core musculature, exercises such as curl-up or push-up performed on an exercise ball.{{cite journal|title=Electromyographic comparison of the upper and lower rectus abdominis during abdominal exercises|journal=The Journal of Strength and Conditioning Research|last1=Clark|first1=K. M.|last2=Holt|first2=L. E.|last3=Sinyard|first3=J.|year=2003|volume=17|issue=3|pages=475–483|doi=10.1519/1533-4287(2003)017<0475:ecotua>2.0.co;2|pmid=12930172|s2cid=23688868 }} An unstable surface increases activation of the rectus abdominis muscles (abdominals) and allows for greater activity per exercise when compared to a stable surface. Exercises such as a curl-up on an exercise ball yields a greater amount of electromyographic (EMG) activity (electrical activity produced by muscles) compared to exercises on a stable platform. Performing standard exercises, such as a push-up, on an unstable surface can be used to increase activation of core trunk stabilizers and in turn provide increased trunk strength and greater resistance to injury.{{cite journal|url=https://www.tandfonline.com/doi/abs/10.1080/17461391.2011.577240|title=Comparison of EMG activity during stable and unstable push-up protocols|last1=Anderson|first1=Gregory S.|last2=Gaetz|first2=Michael|last3=Holzmann|first3=Matt|last4=Twist|first4=Peter|journal=European Journal of Sport Science|year=2013|volume=13|issue=1|pages=42–48|doi=10.1080/17461391.2011.577240|s2cid=145637535|url-access=subscription}}

This large plastic ball, known as a "birth ball", can also be used during labour to aid the descent of the fetal head into the pelvis. Sitting in an upright position will also aid fetal positioning and is more comfortable for the woman. Sitting on the ball with arms placed on a bed, table or otherwise sturdy object for support and gently rocking the hips may help with the contractions and aid the natural physiological process of birth.{{cite book

}} However, using the ball as an alternative to normal seating (such as in the office) can result in discomfort due to the lack of back support.{{cite web|url=https://www.washingtonpost.com/lifestyle/wellness/stability-ball-balance-core-calories/2020/09/29/0b485c74-feb4-11ea-9ceb-061d646d9c67_story.html|title=You might want to rethink using a stability ball as your desk chair|last=Chang|first=Elizabeth|newspaper=The Washington Post|date=September 29, 2020|access-date=April 20, 2021}}
Eight exercise balls are used in the game Treibball. In the context of this sport, the balls are referred to as "rolling sheep".{{Cite web |last=Hill |first=Poppy |date=2022-08-14 |title=What is the dog sport Treibball? |url=https://dogsportscentral.com/what-is-treibball/ |access-date=2024-08-06 |website=Dog Sports Central |language=en-US}}
