Sample Answer
- The muscular system experiences increased fatigue due to poor biomechanical loading, particularly in the quadriceps and calves, leading to reduced force production and potential strain injuries.
- The skeletal system absorbs irregular impact forces through misaligned joints, especially in the ankles, knees and hips, which increases the risk of stress fractures and joint inflammation.
- The circulatory system works harder than necessary to maintain oxygen delivery as inefficient movement patterns require greater energy expenditure, potentially leading to early onset of cardiovascular fatigue.
- The respiratory system struggles with increased oxygen demand due to biomechanical inefficiency causing greater energy requirements and faster onset of anaerobic threshold.
- Immediate first aid requires monitoring vital signs including heart rate, blood pressure and signs of heat exhaustion or dehydration to prevent system failure.
- Secondary first aid responses must address specific muscular and joint injuries through the RICER protocol while assessing for more serious conditions like compartment syndrome.
- Long-term management protocols should include technique analysis and correction through video assessment and professional coaching to prevent recurring system stress.
- Prevention strategies need to incorporate proper warm-up routines, regular technique checks and appropriate training loads to maintain efficient movement patterns and reduce system strain.
