8               Factors that must exist
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting popliteal entrapment syndrome or death from popliteal entrapment syndrome with the circumstances of a person's relevant service:
(1)          running or jogging an average of at least 20 kilometres per week for the six months before the clinical onset of popliteal entrapment syndrome;
(2)          undertaking vigorous physical activity involving repeated active plantar flexion of the foot of the affected leg, or repetitive sudden and forceful contraction of the calf of the affected leg, at a minimum intensity of six METs, for an average of at least 20 hours per week for a continuous period of at least the six months before the clinical onset of popliteal entrapment syndrome;
Note 1: Vigorous physical activity may include driving heavy vehicles, martial arts, physical training, and sports such as rugby, soccer, basketball, rowing or cycling.  Patients typically have hypertrophy of the plantar flexor muscles, including the gastrocnemius, soleus and plantaris muscles.
Note 2: MET is defined in the Schedule 1 - Dictionary.
(3)          having trauma to the affected limb, involving the popliteal fossa and displacing the popliteal artery, within the five years before the clinical onset of popliteal entrapment syndrome;
(4)          having a disease involving the popliteal fossa and displacing the popliteal artery, at the time of the clinical onset of popliteal entrapment syndrome;
Note: disease involving the popliteal fossa is defined in the Schedule 1 - Dictionary.
(5)          running or jogging an average of at least ten kilometres per week for the three months before the clinical worsening of popliteal entrapment syndrome;
(6)          undertaking vigorous physical activity involving repeated active plantar flexion of the foot of the affected leg, or repetitive sudden and forceful contraction of the calf of the affected leg, at a minimum intensity of six METs, for an average of at least 20 hours per week for a continuous period of at least the three months before the clinical worsening of popliteal entrapment syndrome;
Note 1: Vigorous physical activity may include driving heavy vehicles, martial arts, physical training, and sports such as rugby, soccer, basketball, rowing or cycling.  Patients typically have hypertrophy of the plantar flexor muscles, including the gastrocnemius, soleus and plantaris muscles.
Note 2: MET is defined in the Schedule 1 - Dictionary.
(7)           having trauma to the affected limb, involving the popliteal fossa and displacing the popliteal artery, within the five years before the clinical worsening of popliteal entrapment syndrome;
(8)          having a disease involving the popliteal fossa and displacing the popliteal artery, at the time of the clinical worsening of popliteal entrapment syndrome;
Note: disease involving
