Blatnik et al. (2014) investigated the effects of relative load between 30 — 100 % of 1RM in the straight bar deadlift reported that ground
reaction forces increased from 30 — 100 % of 1RM.
Comparing the effects of different training variables, Swinton et al. (2011a) found that ground
reaction forces increased with increasing relative loads from 10 to 80 % of 1RM with both the straight bar and hexagonal bar deadlifts.

Clamping the cord, especially at an early stage, may also cause the extra blood trapped within the placenta to be
forced back through the placenta into the mothers blood supply with the third stage contractions.32 33 This feto - maternal haemorrhage (FMH)
increases the chance of future blood group incompatibility problems, which occur when the current baby's blood enters the mother's blood stream, causing an immune
reaction which can be reactivated in a subsequent pregnancy, destroying the baby's blood cells and causing anaemia or even death.
