Safe and effective training for active, aging adults requires an understanding of the human life span. Senescence (biological aging) begins at age 30! Who they are in their 30’s, 40’s, 50’s, changes when reaching 60, 70, 80 and beyond. Using the same fitness programming for all these age spans can range from downright risky to simply ineffective. An understanding of the human life span is required if trainers are able to match the training to goals, skills, abilities and needs from decade to decade. Determine appropriate methods for training the aging populations by understanding what you (the fitness professional can do) to effect change in fall risks, functional fitness and assessment. Take an educated and purposeful approach to fitness programming for this quickly growing and ever increasing market.
