Adaptations to RT

Week 2 Notes

Adaptations to Resistance Training include: Neural Muscular Cardiovascular Endocrine Connective Tissue
Neural Adaptations: Increased Neural Drive --> Increased Muscle Agonist Increased Firing Rate Increased Pattern and Timing of Discharge
Neural Adaptations: Increase is maximum strength and power --> Increased motor unit recruitment Increased rate of motor unit firing Increased synchronisation of firing
What Muscular Adaptations occur when undertaking a resistance training program? 1. Hypertrophy (cross sectional area, increased synthesis/decreased degradation of contractile proteins, increased no* of myofibrils within muscle fibres) 2. Fibre Size Changes 3. Fibre Type Transitions (slow twitch/fast twitch) 4. Cytoplasmic density
Connective Tissue Adaptations --> Bones: mechanical loading (osteoblasts), increased hypertrophy, increased bone mass, greater BMD in resistance trained athletes Tendons/Ligaments/Fascia: high intensity loads = growth of tissue Cartilage: greater weight bearing abilty
Endocrine Responses include --> 1. Acute changes during/after exercise 2. Chronic changes in the acute responses to a workout 3. Chronic changes in resting concetrations 4. Changes in receptor content (increased testosterone up to 30 mins post exercise
Cardiovascular Adaptations --> 1. Acute responses: HR, SV, CO, BP 2. Increased left ventricular wall thickness
The adaptations to aerobic and resistance training --> Decreased strength and power gains, no effect on aerobic adaptations, concurrent training seems to affect power development more than strength development
