model would suggest a certain training load (reps, sets) and diet (food plus supplements) should yield the same response. The reality is that the musculoskeletal, digestive and nervous systems interact and can either enhance or supress each other’s responses. The non-responding client may, for example, have a gut microbiome imbalance preventing absorption of the nutrients required to increase muscle mass. They may also have central nervous system problems: mental fatigue, poor sleep patterns and emotional issues such as depression and anxiety have been shown to have a negative influence on physical training outcomes. From a therapist’s point of view, it is important to understand that chronic (long term) pain actually alters both brain chemistry (neurotransmitter profiles change) and affects how different areas of the brain communicate. Neurotransmitters are the chemicals that brain cells use to The 30-second article • Human bodies respond differently to the same training or treatment intervention • The body’s various systems, including the nervous, musculoskeletal, endocrine, digestive and cardiovascular systems, interact and can either enhance or supress each other’s responses • A gut microbiome imbalance, for example, may prevent absorption of the nutrients required to increase muscle mass, and thereby negatively affect hypertrophy • The nervous system has three elements: the central nervous system (brain, spinal cord and nerves), autonomic nervous system (parts of the brain and nervous system that control automatic functions of the body) and enteric nervous system (gut) • The far-reaching nature of these three elements means that positively influencing the nervous system will have a corresponding effect on the rest of the body’s systems.
