Recent studies point to HRV as being
helpful in deciding how much and when an athlete should train. For example, a
group of Finnish researchers (Kiviniemi et al 2007) compared HRV guided training
during a generic training programme. The researchers monitored two groups of
moderately trained athletes. The athletes trained six days a week for 40
minutes a day. Group 1 followed an identical training plan and group 2 adjusted
their daily workload by using HRV indices. Both groups trained for a period of four
weeks.
The authors found that the HRV-trained group
displayed a greater training effect compared to the generically trained
group. The study gives support to our recommendation that training should
be individualized for optimum gains. We must acknowledge however, that this
study was limited in its duration (only 4 weeks) and as it included only
moderately trained runners its application to better trained athletes is not
clear.
Nevertheless, the findings from
this study and other recent studies do point to the practical usefulness of HRV when
used as a daily guide for training type and intensity.
Team Sport Monitoring
While HRV measurement may be
conveniently used with individual athletes its practical use with team players
has in fact been limited due to the complex nature of gaining a daily reading
with a large number of players. However, the author has noted that in a camp
environment it is relatively straight forward to gain HRV recordings using any
one of a number of commercially available systems. When a team does not come
together on a daily basis it becomes more of a logistical issue however. With
recent advents and innovations in digital and iphone technology there is
potential nonetheless to acquire HRV recordings in team players. For example
the people at www.myithlete.com are preparing a team system where individual
players or athletes can record their HRV reading in the morning and then that
recording can be emailed to the coach or to a common file in dropbox. Other HRV
technologies such as those offered by Firstbeat Technologies offer Team
monitoring systems which can be used to remotely manage athletes who may be
competing in a different continent.
The recent introduction of such
technology offers teams and their coaches a more accessible and convenient
means of gaining regular HRV and other subjective information which will all be
most useful in monitoring the athlete and player no matter where in the world
they train or compete.

i have kept HRV records for a few weeks now, and found that it is down the morning after hard training sessions. Using the HRV along with general feelings of freshness is helping me guide my training and it seems to be working! Thanks for the article!
