Adding elastic resistance to free weight bench press better for muscular strength and power
Feb 18th
Free weight isotonic resistance using barbells continues to be the ‘gold standard’ for strength training for power lifting. Recently, strength and conditioning professionals have added elastic resistance to free-weight exercises such as the bench press and squat to increase strength, power and speed. The additional downward force of the band during the early phases of the lift provides increased eccentric loading which may provide greater stimulus for gains in strength and power. In theory, the greater eccentric velocities may shorten deceleration time, which may increase the rate of force development with training.
Adding ‘variable resistance training’ using elastic bands is also thought to provide increased resistance where the joints have more leverage in earlier phases of the lift, with decreasing loads during periods of less leverage near later phases of the movement such as the bottom of the squat. When reviewing the literature on the benefits of adding elastic resistance bands to free weight exercises, some studies suggest it improves strength and power, while others do not.
A study published in the Journal of Strength and Conditioning Research compared traditional bench press training with and without the addition of external variable resistance loads (elastic bands and heavy chains). 36 Division-I AA football players were More >
Thera-Band® elastic bands as effective as expensive weight machines
Jan 27th
Muscle strengthening activities are now recommended as part of a regular exercise program. The recent Physical Activity Guidelines issued by the Centers for Disease Control (CDC) in the United States recommend strengthening exercises for all adults at least twice a week. Unfortunately, only about 20% of adults participate in regular strengthening exercises (CDC, 2006). Access to strength training equipment is frequently cited as a barrier to meeting this recommendation. Researchers in Spain compared 2 training programs using either weight machines or Thera-Band® resistance bands. They wanted to determine if there were any differences between band or machine strength training. 45 middle-aged women were randomly assigned an elastic group, a machine group, or a non-exercising control group. The 2 strength training groups performed the same exercises, using the OMNI scale of perceived exertion to be sure both groups trained and progressed at the same intensity. The periodized program lasted 10 weeks for 2 sessions per week. After the training, both groups significantly increased their muscle mass and decreased their fat mass, as well as improved in muscular endurance. There was no significant difference between the groups; both groups improved significantly more than the control group. Researcher Drs. Juan Carlos Colado and N. Travis Triplett noted that elastic bands were 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.
New book helps develop “Effective Functional Progressions in Sport Rehabilitation”
May 20th
Developing functional exercise programs for athletes is sometimes difficult, particularly for rehabilitation professionals without much experience in their patients’ sport. Human Kinetics recently released the book, Effective Functional Progressions in Sport Rehabilitation by Todd Ellenbecker, Mark De Carlo, and Carl DeRosa. The book is divided into 2 parts. Part I provides the benefits and guidelines for developing successful sports rehabilitation programs, while Part II reviews functional progressions for 3 body regions: upper extremity, lower extremity, and trunk.
Functional Exercise Progressions
Each regional chapter reviews relevant functional anatomy and describes appropriate functional tests with normative data. The normative data can be used to set goals for the athletes’ rehabilitation, which can be very helpful to practicing clinicians. Exercises are grouped into specific progressions and labeled with different stages in the progression. The exercises start with isolated, joint-specific exercises and progress to more functional movements. Some exercises also include “Pearls of Performance,” which provide additional hints on performing and progressing the exercise. The 3 chapters also include interval programs that provide specific exercise protocols for returning to sports such as tennis, baseball, football, soccer, and basketball. The exercises include easy to use and convenient equipment such as elastic tubing, dumbbells, and exercise balls, making them More >
New article reviews different forms of variable resistance testing
Apr 6th
A new article in the Strength and Conditioning Journal reviews the latest biomechanical research on 3 types of variable resistance training: cams and levers, chains, and rubber-based resistance.
