Thera-Band exercises help cancer recovery
Jul 22nd
As cancer survival rates increase, older adults are living longer, but often at a lower functional level after cancer treatments. Researchers at Duke University combined home-based Thera-Band exercises for cancer survivors with dietary information in a 12-month program using telephone counseling and mailed print material. The randomized, controlled clinical trial included 641 survivors of colorectal, breast, and prostate cancer between 65 and 91 years old. The results, published in the Journal of the American Medical Association (JAMA), showed that cancer surviors participating in the exercise and diet program had less functional decline than the control group not receiving the program. The program participants also significantly improved in lower extremity function, physical activity level, dietary behavior, quality of life, and lost nearly twice as much weight as the control group. The “RENEW” (Reach out to Enhance Wellness) study was supported by Thera-Band Academy for several years.
Elastic resistance improves function in older adults
Jul 9th
An article recently published by USAToday about a Cochrane review of research on improving function in older adults with resistance training noted that elastic resistance bands are effective:
“In a review of 121 clinical trials that looked at weight-lifting in people over age 60, researchers led by Chiung-ju Liu of Indiana University at Indianapolis, conclude that weight lifting two to three times a week makes everyday tasks easier for the elderly.
“Older adults seem to benefit from this type of exercise even at the age of 80, and even with some type of health condition,” Liu says, in a statement. “The data support the idea that muscle strength is largely improved after the training, and the impact on older adults’ daily activities can be significant.”
Free weights, exercise machines or elastic “resistance” bands (their weight adjusted to the progress of the study participants) all showed benefits. They included “large improvement” in strength and “moderate to large improvement” in tasks such as climbing stairs, according to the study the Cochrane Database of Systematic Reviews.”

Thera-Band Program Teaches Exercises for Pregnancy in India
Jun 11th
Finding safe exercises during pregnancy for both mom and baby is quite challenging. In India, physiotherapist Shabnam Agarwal is leading both pre- and post-natal exercise classes at the Belle Vue Clinic in Kolkata. They use Thera-Band resistance bands both in weekly classes, and at home. “It helps them carry and lift the baby, and eventually be able to do it better with less physical strain,” said Agarwal. The Thera-Band resistance exercises strengthen the chest, arms, and help with abdominal strength as well. Participants then progress to a Thera-Band exercise ball. She added, “It’s fun to see the mothers gaining more confidence with their exercises and feeling that they have more fit bodies.” Learn more about the Thera-Band program from a participant’s point of view.

Top 10 Myths of Elastic Resistance
May 7th
by Phil Page, PT, ATC
1. There is very little scientific evidence on elastic resistance. FALSE! There are over 100 published randomized, clinical trials (the highest level of evidence) that have used elastic resistance. In addition, there are over 60 basic and applied studies that have been published to describe the scientific foundation for elastic resistance, including electromyographic (EMG) evidence and biomechanical analysis. The most comprehensive and updated list of these references is available at www.Thera-BandAcademy.com.
2. Isotonic or machine-based resistance is more safe & effective than elastic resistance. FALSE! The injuries and rates reported with using elastic resistance in the literature are as small if not smaller than using isotonic resistance. Scientific evidence proves that the resistance provided by elastics is very similar to isotonic resistance in physiologic response, strength outcomes, and patterns of muscle activation.
Thera-Band Torque, compared to isotonic weights
3. In contrast to isotonic resistance, the strength curve (torque at the joint) of elastic resistance is linear & ascending. FALSE! Many people confuse FORCE (resistance) with TORQUE (force x distance). This has led to the misperception that isotonic resistance is more “functional” to the strength capacity of muscles than elastic resistance. The FORCE produced by elastic resistance is linear and ascending, meaning that resistance increases proportional More >
