I started coaching High Jumpers after college in 1979 (two years on Ice Breaker was my break from track) - This allowed me a place to train - learned some stuff along the way.
Have had some reasonable success and enjoyed working with the many jumpers at many levels since then - D1, D2, D3 and high School
This info will hopefully help - some geared towards us masters folks - been watching alot of the Diamond League - knee drive and quicken the last two steps is so important - I will develop as I can - any questions please ask.
Many young jumpers do not want to pay attention to this part - which I feel is the most important part - running a good consistent approach that puts you in the correct position to maximize the jump - convert horizontal to vertical - practice this at almost every jump session -
below are two articles that go over this - can get a bit technical - but heck - I am an Engineer so I did not mind reading
Good site that has lots of training info and video links - I have had some jumpers go to their camps with very positivie results -- Kangaroo Track CLub
Basic concept is early season lots of drills and approach work - as you get to bigger meets - you have to jump high (or attempt higher hgts) - since this is geared towards flop - I will address rollers later
Big sit out over the bar (not recommended) versus rotate and flip or straighten the legs to clear - here is where an example helps - how does a figure skater spin or rotate faster - pull arms in - since we are rotating about axis near hips the splayed leg or frog leg position can help this rotation - Noel Ruebel does this well -
