Public health guidelines primarily focus on the promotion of physical activity and steady-state aerobic exercise, which enhances cardiorespiratory fitness and has some impact on body composition. However, research demonstrates that resistance exercise training has profound effects on the musculoskeletal system, contributes to the maintenance of functional abilities, and prevents osteoporosis, sarcopenia (loss of body mass), lower-back pain and other disabilities.
More recent seminal research demonstrates that resistance training may positively affect risk factors such as insulin resistance, resting metabolic rate, glucose metabolism, blood pressure, body fat and gastrointestinal transit time, which are associated with diabetes, heart disease and cancer. Research also indicates that virtually all the benefits of resistance training are likely to be obtained in two 15-to-20 minute training sessions a week. Sensible resistance training involves precise controlled movements for each major muscle group and does not require the use of heavy resistance. Along with brief prescriptive steady-state aerobic exercise, resistance training should be a central component of public health promotion programs.
BENEFITS OF AN EFFECTIVE PROGRAM
HEALTH
Increases HDL – High Density Lipoprotein (good cholesterol) and decrease LDL – Low Density Lipoprotein (bad cholesterol).
Reduces risk of diabetes and insulin needs.
Lowers risk of cardiovascular disease.
Lower high blood pressure.
Lowers risk of breast cancer – reduces high estrogen levels linked to the disease.
Decreases or minimizes risk of osteoporosis by building bone mass.
Reduces symptoms of PMS (Premenstrual Syndrome)
Reduces stress and anxiety.
Decreases colds and illness.
STRENGTH
Increased muscle strength, power, endurance and size. Enhanced performance of everyday tasks. You will be able to do everyday tasks like lifting, carrying and walking up stairs with greater ease.
FLEXIBILITY
By working the muscles through a full range of motion, weight training can improve your overall body flexibility. Increased flexibility reduces the risk of muscle pulls and back pain.
LIKELIHOOD OF INJURY
Strong muscles, tendons and ligaments are less likely to give way under stress and are less likely to be injured. Increased bone density and strength reduces back and knee pain by building muscle around these areas.
BODY COMPOSITION
Boosted metabolism (which means burning more calories when at rest). Reduced body fat. Your overall weight may not change, but you will gain muscle and lose fat. Over time you should notice decreases in waist measurements and bodyfat measurement.
MUSCLE TONE
The conditioning effect will result in firmer and better-defined muscles.
POSTURE
The way you sit and stand are influenced by the health of a network of neck, shoulder, back, hip and abdominal muscles. Stronger muscles can help you stand and sit straighter and more comfortably. Improved balance and stability.
STATE OF MIND
As you begin to notice the positive physical changes in your body and develop a regular exercise routine your ability to handle stress effectively will improve. Weight training allows you to sleep better, i.e. fall asleep quicker and sleep deeper. Clinical studies have shown regular exercise to be one of the three best tools for effective stress management.
