Some controversy surrounds the role that stretching exercises play in regard to fitness training, especially group fitness classes. Perhaps more than ever, debate is brewing about the proper time and place to stretch. Exactly when and what type of stretching exercises do we need to include in our classes? Although little definitive research is available on the subject, fitness experts are trying to reach a consensus.
Good news for those who don’t enjoy “pushing a stretch.” Many people think that stretching at an intensity of “8” on a scale of 1–10 is an effective way to enhance flexibility. New research shows otherwise. For increasing active and passive ranges of motion, it seems that conventional stretching is no more effective than either strengthening agonist muscles or decreasing resistance of antagonist muscles through low- intensity stretching.
The condition of our connective tissue depends on two factors—how old we are and what we have done in our lives to keep our tissue healthy, hydrated and flexible.
The health of connective tissue is a serious concern for older people, as movement restrictions can make it hard for them to perform simple activities of daily living. While personal trainers often develop flexibility programs and modify exercises to help senior clients succeed, there is another valuable technique to improve seniors’ range of motion.
Many men struggle with inflexibility and diminished joint range of motion, especially as they age, and stretching is often the most poorly performed component of their exercise programs. You can help male participants to develop an effective active-stretching program by incorporating continuously looped resistance bands into your cool-down. This approach may help men with over tight hips to restore agility, strength, power and balance.
