The Effects of Weight Lifting on Degenerative Disc Disease

Author
by JESSICA BRUSO

Some people begin to suffer from degenerative disc disease, or DDD, as they age. This happens when the discs in between your vertebra begin to wear down and become damaged. If you have back pain that spreads down to your upper thighs and buttocks, you may have DDD. Weightlifting may help improve your DDD symptoms if done properly, but you shouldn't start to lift weights without first discussing it with your doctor or physical therapist.

Stabilization Program

If you suffer from lower back pain due to DDD, your physical therapist may have you undergo a stabilization program, which involves exercises using your body weight that increase the strength of your core muscles. This can help prepare you for safely lifting weights to further strengthen your muscles and limit your back pain. Examples of stabilization exercises include lying on your back and marching your feet, bridges and lying on your stomach and raising opposite arms and legs

Weight Training

Once your doctor or physical therapist approves weight training, choose exercises that strengthen your back, abdominals, legs and arms so you limit the pressure put on your spine during your daily activities. While lifting weights, pause at the top before lowering the weights, as a study published in 2001 in the "British Journal of Sports Medicine" found that this combination of dynamic and static weight training most effective for strengthening the muscles involved in chronic lower back pain.

Weight Lifting Safety

While weight training, take steps to limit your risk for further injury. Use low weights and higher repetitions rather than using heavy weights, try to use machines instead of free weights and use a spotter when you do use free weights. Ask your doctor whether he recommends you wear a weight belt while lifting to help protect your back.

Considerations

If you have degenerative disc disease, speak with your doctor or physical therapist to verify which exercises you should perform and how much weight you should lift. Certain exercises are not recommended for people with back problems, including the dead-lift, snatch, clean-and-jerk and squat, as these are more likely to harm your back.

Gym Exercises You Can Do With a Slipped Disc

Author
by KYLE CLAYTON

The role of a spinal disc is to provide a cushion between the vertebrae of your spine. When one of these discs slips out of place, the result is back in the lower back, with pain and numbness sometimes extending down into the legs with the constriction of the sciatic nerve. After the initial pain of a slipped disc has settled, you can carefully begin rehabilitation with exercise. Consult with your doctor to ensure you are healthy enough to begin an exercise program. Exercising without a doctor's consent may worsen a slipped disc.

Lower Back Stretch

The lower back stretch can relieve tightness of the muscles around the spine that may be causing discomfort to your slipped disc. To perform a lower back stretch, lie on your back on the floor. Keep your arms at your sides and bend your knees. Rotate your knees over to one side as far as they can go, and hold the position for at least 20 seconds. Breathe normally, do not hold your breath. Once 20 seconds has passed, move your knees to the other side for another 20 seconds.

Aerobic Exercise

In addition to cardiovascular benefits, aerobic exercise is a low-impact way of strengthening the muscles of your back, glutes and legs. In particular, swimming has been shown to decrease back pain, according to the "New York Times Health Guide." Other options include jogging and riding a bicycle.

Crunches

Abdominal strength is a major component of a healthy back, according to the Sports Injury Bulletin. To perform abdominal crunches, lie flat on your back with your knees bent and your feet on the ground. Your hands should be at your chest. Contract your abdominal muscles to crunch the shoulders and head off the floor, then return to neutral position. Do not sit up all the way. Repeat for a total of 8 to 10 repetitions.

Supermans

Supermans strengthen your abdominal muscles and your glutes. To perform a superman, get down on all fours. Both knees and both hands should be touching the ground in a neutral position. Slowly extend your left arm straight forward. At the same time, raise your right leg and extend it straight backwards. Hold the position for three seconds and then do the other side. Perform 8 to 20 repetitions per side.

Plank

Lie on your stomach on the floor. Prop yourself up on your elbows, then raise up to your toes so that only your elbows and toes are touching the ground. Keep your back straight, do not let your hips dip or curve. Hold this position for 10 to 30 seconds.

Back Extensions

Lie face down on the ground with your hands behind your head. Raise your chest and head off the ground while simultaneously contracting your glutes to raise your legs. Lower, and repeat for 8 to 10 repetitions.

Highlights

•

A simple yet efficient “top-down” method for fabricating anisotropic transparent paper directly from wood was developed.

•

The wood-derived paper has anisotropic microstructures and light scattering due to the well-aligned cellulose fibers.

•

The anisotropic paper possesses both high transparency and high haze, enabling its utilization in GaAs solar cells.

•

The “top-down” approach for preparing anisotropic transparent paper is facile, scalable, cost-effective and “green”.

Abstract

The growing demand for flexible electronics and solar energy conversion devices has fueled a search for high-quality paper-based materials with excellent mechanical flexibility and optical properties such as high transparency and haze. Despite the tremendous efforts have been dedicated to developing paper-based materials with high transparency or high haze, challenges still remain in achieving both due to the general exclusivity between them. Here, for the first time, we develop a novel anisotropic paper material possessing high mechanical flexibility and fantastic optical properties with both high transmittance (~90%) and high haze (~90%) simultaneously via a simple yet effective “top-down” approach by directly shear pressing the delignified wood material. The anisotropic transparent paper demonstrates a high efficiency as a light management coating layer for GaAs solar cell with a significant efficiency enhancement of 14% due to its excellent light management capability with both high transparency and high haze. The presented “top-down” approach is facile, scalable, cost-effective and “green”, representing a promising direction for developing flexible electronics, solar energy conversion devices and beyond.

Graphical abstract

We demonstrated a highly simple yet efficient “top-down” method for fabricating anisotropic transparent paper by directly shear pressing the delignified wood. The anisotropic paper with both high transmittance of ~90% and high haze of ~90% can be used as a light management coating layer to significantly improve the energy conversion efficiency of GaAs solar cells.
