... Energie pro HIIT program se pokrývá jak anaerobní, tak i aerobní formou, což má za následek zvýšení úrovně klidového metabolismu (Meuret, 2007;King, 2001;Treuth, 1996;Broeder, 1992). Pokud se totiž podíváme na obrázek (obrázek 2), tak lze vyčíst, že při kontinuální zátěži spálíme velké množství kalorií při samotném cvičení, kdežto vlivem intervalového HIIT spálíme část při cvičení, především několik hodin po relaci samotné (Smith, 2008), a to díky pozátěžové extrémní spotřebě kyslíku, která po dalších 24 hodin zvýší klidový metabolismus. ...
The HIIT – High Intensity Interval Training has become an increasingly used term in foreign publications
and this method is frequently implemented in training processes of many athletes. However not
every athlete or trainer is aware of the physiological changes which are caused by this form of training.
In order to improve the training process it is important to compare the effectiveness of HIIT with
the continual training method or other forms of the interval training. The aim of this publication is to
analyze and describe the effect of various forms of HIIT according to the set markers: primarily VO2max
(maximal oxygen uptake) – interval training effectiveness marker, secondarily lipid utilization, and
last but not least hormonal and enzymatic level changes. Another objective of this publication is the
clarification and explanation of energy coverage, metabolism and cardio-respiratory function during
the application of HIIT method.
Within the research plan we focused exclusively on the foreign studies (n = 150) conducted in years
1978–2015 from which we chose 70 studies from databases such as SportDiscus, Web of Science, ACSM
Journal, PubMed. The selection was based on the preselected criteria – length of the research, nature of the research group and intervention frequency etc. For the purpose to extend the theoretical bases
of the problematics of energy coverage, metabolism and cardio-respiratory function were analyzed
several chosen studies from last 10–15 years. The analysis of the individual markers was conducted
based on the publications from the last decade. The research has shown that the HIIT has a significant
effect on the increase of VO2max. Further findings also showed that the subject is able to adapt to this
type of training in just two weeks which enables the duration of training process to shorten. This type
of training also leads simultaneously with EPOC effect (post-exercise oxygen consumption) to higher
energy consumption in tens of hours.
The presented results can be used in Sports practice to overcome the performance stagnation and
lead to performance improvement as a result of the HIIT method implementation.
Certain studies show that the HIIT method is also successfully applicable to the overweight individuals,
patients with Diabetes mellitus and people with sedentary lifestyle.
However, it is always necessary to ensure the individual approach and to avoid the risk of overtraining.
