ALTITUDE TRAINING 6
This fourth issue of Volume 17 of Coaching Science Abstracts is the sixth issue that reviews articles concerned with altitude training. It adds to the abstracts presented in Volume 2(4), Volume 5(4), Volume 8(4), Volume 11(4), and Volume 14(4). Many of the research problems noted in those issues persist to this day.
[Editor's note: In this and previous issues related to this topic, altitudes greater than 2,500 m are often referenced. It is a rare event where serious sporting competitions are held at altitudes greater than 2,500 m – that being a legacy of the 1968 Mexico Olympic Games. For altitudes greater than 3,000 m, the relevance of those studies is more appropriate for mountain climbing and some military activities. When reading these abstracts, this difference should be remembered and exact credence for sports be given to studies that relate findings at altitudes no higher than 2,500 m.]
