As we age, we lose muscle mass through a condition called “sarcopenia,” which is the age-related loss of muscle fibers. Sarcopenia can lead to decreases in strength and function in older adults, which can increase the risk for disability and injury.Muscular power and reaction time are also important components of function and injury prevention for older adults; specifically, reduced strength of ankle dorsiflexion is associated with an increased risk of falls (Skelton et al. 2002; Whipple et al. 1987). In addition, decreased reaction time is associated with increased falls and motor vehicle accidents in older adults. Power training, which is essentially strength training performed at higher velocities, is becoming increasingly popular for older adult exercise programs. Many studies have shown that strength training exercises can increase strength and function in older adults, but few if any have examined effects of ankle power training on performance or injury prevention in older adults. In addition, few studies have directly compared elastic and isotonic resistance training programs.

Thera-Band® resistance helps female cancer survivors keep fit after chemotherapy
Aug 10th
Breast cancer survivors often experience weight gain after chemotherapy, particularly pre-menopausal women. This weight gain has been associated with an increased recurrence and death from breast cancer (Chlebowski et al. 2006). Researchers at the University of Washington and Oregon Health Sciences University suggested that exercise may be a low-cost, non-pharmacologic strategy to prevent or reverse weight changes in female cancer survivors. In their randomized controlled study, 112 women newly diagnosed with cancer were randomly assigned to a resistance exercise group, aerobic exercise group, or a control group (usual care). Both exercise groups performed their routines 4 times per week at their home for 12 months. Each exercise routine took 20 to 30 minutes and the exercises used the Borg Scale to maintain a “moderate” intensity level.
The resistance exercise group used Thera-Band® resistance bands or weight equipment in their home. They performed 3 to 4 upper and lower body exercises for 2 sets of 12 to 20 repetitions with progression in the resistance levels. The aerobic exercise group performed enjoyable weight-bearing activities such as walking, jogging, or dancing. Subjects were assessed before the study, half-way through the study (6 months), and at the end of the 12 month study for body weight, More >
Thera-Band® exercises safe and effective for patients with hemophilia and bleeding disorders
Jun 29th
Bleeding disorders such as hemophilia may cause bleeding in the joints, known as ‘hemarthrosis.’ This may lead to arthritis and subsequent joint replacement surgery. Exercise is an important component in managing hemarthrosis; however, many patients are hesitant to exercise for fear of injury and resulting bleeding. Few studies have examined the effectiveness of exercise in hemophilia patients.
Previously, German researchers created a strength and proprioceptive training program using Thera-Band elastic resistance and Stability Trainers. The results, published in 2003 noted improvements in strength and proprioception. The authors felt that a balance training component was important to prevent fall-related injuries in persons with hemophilia.
More recently, researchers at the University of Tennessee Health Sciences Center created an individualized 6-week program using Thera-Band resistance in 33 patients with bleeding disorders. They used 3 levels of progression based the participant’s strength. Download the Thera-Band exercise protocol here. The patients then used a specific color of Thera-Band resistance corresponding to the prescribed intensity (% of an isometric manual muscle test). Subjects also performed stretching and cardiovascular exercise. A physical therapist supervised the program 2 days a week. At the end of the 6-week program, there were no injuries, pain, edema, or bleeding episodes reported. The patients significantly More >
Elastic resistance exercise program effective in high school-based exercises for teens
Jun 22nd
Elastic tubing has been proven as effective as free weights again; this time, in teenagers. Several studies have shown that Thera-Band® elastic resistance has similar effects on muscle activation and strength as isotonic resistance (Andersen et al. 2010; Colado & Triplett 2008). Current physical activity guidelines recommend resistance training to improve muscular fitness in youths. A randomized, controlled study in Preventive Medicine by Australian researchers was performed to compare the effects of a resistance exercise program in 15 year old boys and girls using either elastic or isotonic free weight resistance compared to a control group. During the 8-week program, both groups trained twice a week with a PE teacher with a 1:15 instructor-to-participant ratio. They began each session with 5 minutes of aerobic activity and dynamic stretching. Resistance exercises were performed for 2 sets of 8 to 12 reps (Weeks 1-4 = 10-12 reps; Weeks 5-8 = 8-10 reps) with 60 second rests between sets. The 10 strengthening exercises were performed in 40-50 minutes in the same order. Both groups used the Borg scale at 15-18 with an 8-12RM; in other words, participants used a resistance with each exercise that caused fatigue with the last repetition with an exertion level of 15-18 More >
Thera-Band® strength training for older adults: from acute care to home exercise
May 27th
One of the most common clinical mistakes is to arbitrarily assign resistance training levels to older adults, often choosing very low intensities. These low loads are often insufficient to increase muscle strength. Drs. Dale Avers and Marybeth Brown of the American Physical Therapy Association’s Section on Geriatrics published a whitepaper in the Journal of Geriatric Physical Therapy on strength training for older adults.
Both the Section on Geriatrics and the American College of Sports Medicine recommend strength training at 60% of 1 repetition maximum (RM) as the minimal intensity for strength gains. 1RM is the maximal amount of resistance an individual can move for only one repetition. Unfortunately, it’s often difficult to determine 1RM capabilities in older adults. Even using a multiple RM equation to estimate 1RM may not be accurate, since they haven’t been validated in older adults. However, using Thera-Band® resistance to quantify a multiple RM level has been validated in older adults (Manor et al.)
Using a “rating of perceived exertion” or RPE scale has been advocated to better estimate resistance exercise intensity. There are 2 popular RPE scales: the Borg scale and Omni scale. Several studies on older adults using elastic resistance have used Borg’s RPE scale to dose intensity, and More >
