An overview of the importance of ‘Gravity Fitness
An introduction to Gravitational Physiology and links with theSpace Industry
An overview of the principles of exercise for the GravityFit Exercise Model
Explanation of the subsections for the scientific base"
 
SECTION 2: Four aspects of Gravitational (Bone, Joint and Muscle) Physiology
 
Part 2 A – The Evolution of Bipedalism – the effects of ‘loading’ the musculoskeletal system for human bipedalism in Earth’s Gravity
This section explains that, for our upright posture in Earth’s Gravity, we have a ‘whole body’ framework of Anti-Gravity muscles, with the core muscles most important, to function as springs to protect our joints from injuries caused by the high impact forces caused by gravity. This function is assisted in the spine by intervertebral discs to absorb impact loads to protect the vulnerable structures of the spine.
 
Part 2 B – Basic Gravitational Physiology Research – the effects of ‘unloading’ the musculoskeletal system: Laboratory based research
This section explains how ‘unloading’ the body (or parts) reduces Gravitational Load Cues (Sensory Information) to the joints leading to a neuroplasticity of the nervous system. This results in deterioration of ONLY the Anti-Gravity body framework of muscles, with resulting ‘muscle imbalances’ formed around the ‘weightbearing’ joints. This is why ‘unloading’ the body leads to wear and tear and joint injury.
 
Part 2 C – Human Space Research - the effects of ‘unloading’ the musculoskeletal system in microgravity
This section explains that the Anti-Gravity Body Framework is weakened in zero Gravity (microgravity) and ‘muscle imbalances’ are formed, leading to a loss of spinal posture and painful joint problems (e.g. osteoarthritis) on return to Earth. This weakness of the framework is also related to a loss of bone density (osteopororis), and pelvic floor problems. The spinal Anti-Gravity muscles are most affected by the unloading of the whole body, and this is accompanied by rapid and persistent problems developing in the intervertebral discs. The type of exercise used to counteract this weakness developing in the Anti-Gravity Body Framework of muscles is also considered.
 
Part 2 D – Relevance to Bone and Joint Health on Earth 
This section explains that there are many reasons why, when we live in Gravity, the natural Anti-Gravity Body Framework (which is optimal in most underdeveloped countries) breaks down with our modern lifestyles with the formation of ‘muscle imbalances’ and subsequent bone and joint problems. People in the modern world have no understanding of what the Anti-Gravity Body Framework is, how important it is and what aspects of their lifestyles are causing its rapid decline and leading to major medical problems.
 
SECTION 3: The GravityFit Exercise Model is based on a ‘Sensory- Motor’ exercise approach
This section explains that the GFEM is based on a ‘sensory motor’ approach which is essential to optimise bone and joint health. The ‘sensory motor’ exercise approach is also important as it forms the base or anchor for the optimal development of functional motor skills. This section expands on the principles of the GFEM and explains how Gravitational load cues (i.e. encompassing Gravity Sensory Information, Effective Weightbearing Load and Optimal Holding Endurance) target the gravity sensory receptors of the whole body. It also explains how levels of Gravitational load cues can be quantified for safe progression of exercise load and for assessment purposes.
