Neuromuscular training program reduces injury and improves performance in female athletes
Jul 20th
Balance training using Thera-Band® Stability Trainers and balance boards has been shown to prevent sports injuries in several studies. Researchers in Finland investigated the effects of an in-season neuromuscular training program in female floorball players. 27 teams were randomized into either a control group or intervention group that performed a 6-month neuromuscular exercise program. Each team was provided with an instruction book, 8 wobble boards, 8 balance pads, and 8, 1-kg soft weights. The program (download the sports neuromuscular warm-up protocol here) included balance, agility, plyometric, and stretching exercises.
After the 6-month season, participants in the exercise group significantly improved their static balance and jumping speed. There was no difference in improvement between groups in their jump height or agility running speed. In addition, the researchers found 66% lowered risk for leg injuries in the exercise group (the authors published a separate article in the British Medical Journal in 2008). These studies show that an in-season neuromuscular training program including Thera-Band stability trainers, wobble boards, and soft weights can prevent injury and improve performance in female athletes.

Researchers encourage proprioceptive exercises for shoulder rehabilitation
Apr 27th
Proprioceptive exercises are commonly prescribed for lower extremity rehabilitation. More recently, sensorimotor (SMT) proprioceptive exercises have been used for shoulder rehabilitation. It’s thought that shoulder injury (in particular, shoulder instability) is related to proprioceptive deficits. Researchers speculate that deafferentation (loss of sensory information) from the mechanoreceptors of the shoulder joint capsule and altered proprioceptive information create these sensorimotor deficits (Lephart et al. 1997; Tibone et al. 1997)
A review paper in Athletic Training and Sports Healthcare discussed the adaptations of the sensorimotor system following shoulder rehabilitation. The authors used the PEDro system for inclusion criteria to review 23 articles. The most common techniques the paper reviewed included:
- Joint repositioning
- Closed-kinetic chain exercises
- Proprioceptive Neuromuscular Facilitation (PNF)
- Plyometrics
- Joint Perturbations
- Activation of muscle through elastic tubing, free weights or oscillation
The authors concluded that sensorimotor rehabilitation after shoulder injury is crucial, and that the sensorimotor system is, in fact, trainable. A proprioceptive and sensorimotor training program including Thera-Band® elastic bands and tubing, FlexBar® Oscillation, and closed-kinetic shoulder exercises with Stability Trainers should be included as part of a shoulder rehabilitation or prevention program.

Training program improves throwing accuracy in baseball players
Mar 31st
Core training is thought to be important to improve functional sport activities, particularly those involving force transfer through the abdominals and back, into the extremities. For example, much of the strength and power required to throw a baseball comes from the force transmitted through the core from the legs. This is an example of the ‘kinetic chain,” where different parts of the body are interconnected and all contribute in some way to performing a functional activity.
Few studies have investigated the effects of core training on functional performance. Athletic training researchers investigated the effects of a shoulder training program with and without core stability exercises. 19 baseball players were randomly assigned to an open and closed-chain exercise program, or the same program with additional core training. 15 healthy age-matched non athletes were used as a quasi-control group. Each subject was tested for throwing accuracy, core stability, and proprioception before and after the 6-week program.
Both groups performed a shoulder training program that included free weights, closed-chain balance board, step-up, and exercise ball exercises, as well as plyometric ball tosses. The core training group also performed stabilization exercises such as the dead bug, sit-up, bridge, wall slides, and sitting on an exercise ball.

The Best Exercises for Rotator Cuff Strengthening
Mar 2nd
For years, the debate has continued on the ‘best’ exercises for strengthening shoulder muscles. Using electromyography (EMG) to measure muscle activity, researchers have attempted to determine which exercises have the highest levels of muscles activity for strengthening exercises. Several studies have examined EMG of common shoulder exercises to find the best exercises to strengthen the rotator cuff; in particular, the supraspinatus muscle. The “empty can” or “full can” exercises have been the most commonly performed exercise for supraspinatus strengthening, but controversy still exists in the literature.
While high muscle activation levels are often desirable, what’s more important is the relative activation of other muscles during the movement. For example, Dr. Michael Reinold and colleagues suggested in their 2007 paper that a good rotator cuff exercise should produce the greatest supraspinatus activity while minimizing the deltoid activation. Theoretically, reducing deltoid activation decreases the upward shear of the humerus during arm elevation, which may be desirable when prescribing exercise to strengthen the suprapsinatus in impingement patients.
In a study published in Medicine and Science and Sports and Exercise, subjects performed 5 isometric exercises in random order while measuring the EMG activity of the deltoid, supraspinatus, and infraspinatus. The exercises were: full can, empty can, prone elevation, elastic external More >
Thera-Band Exercises for Tennis Players to Prevent Injuries
Sep 13th
As with all sports, tennis injuries are all too common. The repetitive nature of tennis predispose players to many injuries as a result of muscle imbalance. Believe it or not, tennis players suffer from lower extremity injuries more than shoulder injuries. Todd Ellenbecker DPT, MS, CSCS, Director of the Physiotherapy Associates Scottsdale Sports Clinic, recently published an article in Strength & Conditioning Journal on exercises to reduce injury risk in tennis players. In the August 2009 issue, Ellenbecker and his co-authors provided a list of exercises to help reduce injury risk for the shoulder, elbow, hip, and core in tennis players. The exercises dont require expensive machines or equipment; instead, portable and inexpensive Thera-Band® products are suggested including Thera-Band bands, tubing and loops, Thera-Band Soft Weights and Exercise Balls, and cuff weights. As Director of Sports Medicine for the ATP Tour, Ellenbecker and the international team of physiotherapists regularly use Thera-Band products for testing and training professional tennis players.
