Exercises with elastic resistance more effective than passive shockwave treatment
Mar 24th
Shoulder impingement is a common cause of shoulder pain that responds well to active, therapeutic exercise. A more passive “shockwave treatment” has recently been used to treat impingement. This passive modality was compared with an active exercise treatment in shoulder impingement patients in Norway. The study published in the British Medical Journal compared 12 weeks of physiotherapy and home exercise using elastic tubing with 4 to 6 treatments of Radial Extracorporeal Shockwave Treatment (REST).
64% of the exercise patients and only 36% of the shockwave treatment patients had significant improvement in pain and disability, and more patients in the exercise group returned to work. Interestingly however, there were no significant differences between groups in function or range of motion.
This study is consistent with the findings of other studies that show elastic resistance exercises are effective as part of an active care approach to shoulder impingement that includes both clinic- and home-based exercises. Thera-Band® elastic resistance and patient kits are ideal to facilitate both clinical and home exercise programs.

Are elastic resistance squats better than free weight squats?
Mar 1st
The squat exercise is used primarily for hip and knee strengthening. It is considered one of the most fundamental strengthening exercises for strength and power in the legs. Elastic bands have been used to add resistance to the squat exercise while using barbell free weights to offer more dynamic resistance at the top of the squat movement as the resistance of the band is at its highest. No studies have directly compared the effects of squatting with elastic resistance versus free weights.
In a study published in the Journal of Strength and Conditioning Research, researchers compared squatting with equivalent work loads of elastic-resisted and isotonic free-weight squats in trained weight lifters. Subjects squatted with each type of resistance while muscle activity and biomechanical variables were measured. The band-resisted squats resulted in higher force, velocity, power, and quadriceps muscle activity near the top of the squat, which includes the first part of the eccentric phase, as well as the last part of the concentric phase.
The researchers concluded that elastic resistance produces similar resistance patterns as standard free weights, except at the bottom of the squat, where the bands are on less stretch and thus, less tension. More importantly, the researchers stated that elastic band squats More >
Elastic resistance exercise safe and effective for kidney failure patients on dialysis
Feb 11th
The kidneys serve an important function in filtering the blood. Patients with severe kidney disease or kidney failure don’t have the ability to clean their blood. This condition is known as end-stage renal disease (ESRD), and often requires hemodialysis that cleans the blood with a machine. In 2006, over 500,000 Americans had ESRD, with over 350,000 requiring dialysis.
Dialysis patients often have reduced physical function and quality of life because of their disease complications and lack of physical activity. Unfortunately, there is little research on exercise in dialysis patients. Researchers performed a multi-center randomized controlled trial in Spain to determine the effects of a resistance training program with ankle weights and elastic bands.
27 hemodialysis patients were randomly assigned to a resistive-exercise group or a low-level aerobic exercise group. Both groups, supervised by physiotherapists, exercised 3 times a week for 6 months. Each session included 5 minutes of stretching as part of warm-up and cool down, and 25 minutes of either resistance training or stationary bike riding. The resistance training group performed training at an RPE of 12-14, and emphasized lower extremity exercise.
At the end of the study, the resistance training group significantly increased in physical function compared to the control group. The More >
Both Thera-Band and Aquafins resistance improve strength and overall health
Feb 8th
It has been well-established that resistance training improves muscular strength and physical capacity. Other health-related benefits include reduction of body fat and improvement in blood lipids. In addition to traditional isotonic resistance training (free weights, machines), elastic bands and aquatic resistance can be used for strengthening exercises. Research shows that elastic resistance produces the same gains in strength as more expensive weight machines; however, elastic resistance has never been directly compared to aquatic resistance in terms of effectiveness.
Researchers in Spain compared Thera-Band® elastic band strengthening to aquatic strengthening including Aquafins® aquatic training in a group of post-menopausal women. The subjects were randomly assigned to the elastic, aquatic, or non-exercising control group. The 24 week periodized program used the OMNI scale for perceived exertion to ensure both groups trained at the same intensity. Each group performed the same exercises with different types of resistance. After the training program, both the elastic and aquatic groups equally improved their body composition (12-15% reduction in body fat), blood pressure (6-8% reduction), physical capacity (13-52% improvement) and blood chemistry (11% increase in HDL) compared to the control group.
These results confirm that both dry land and aquatic training are effective and beneficial in middle-aged women. This information is particularly useful More >
Thera-Band® resistance or dumbbells? New research supports both in the clinic
Feb 7th
The debate of elastic resistance versus isotonic resistance
Elastic resistance is commonly used in rehabilitation exercises, and has been shown to increase strength and function in over 100 randomized controlled trials (www.thera-bandacademy.com). Even with this amount of clinical evidence, elastic resistance is sometimes criticized because of the difficulty in quantifying intensity. Despite the fact that force elongation charts are available to quantify elastic resistance intensity, it is sometimes difficult to use these clinically. Because of this limitation, few studies have compared elastic and isotonic resistance directly because of the intensity-dosing issue.
Quantifying EMG and RPE of elastic and isotonic resistance
Researchers in Denmark compared elastic and isotonic dumbbell resistances for muscle activation and perceived exertion levels. Healthy females performed 3 different exercises with standard dumbbells ranging from 2 to 7.5 kg, and Thera-Band elastic tubing (red, green, blue, black and silver). The researchers developed a chart comparing isotonic and Thera-Band elastic resistance stretched 125 to 150%.
