[Guest guest]

Thank you Hakan for this information in the JSSM I really appreciate the

articles.

A question to all Rugby coaches and other combat team sport coaches

In this JSSM Combat Special Spoprts Issue there is an article about

measuring the lactate threshold of Judo practitioners and comparing this to

a 3000 meter run (800m at a time to allow sampling of blood). This study

showed that the metabolic response to Judo specific training ws the same as

for the 3000m run.

I have an athlete I am preparing for provincial/international competition.

He is a tighthead prop a position that requires significant work rate in

wrestling type roles, in rucks , mauls and scrums. I add in the

tackling/hitting training which is different from Judo and the running

around the field is also different. However, the province that my athlete

is going to test the players and set a target for a maximum 15 minute 3km

run (5min/km which is not very hard unless you are 120kg). Of course I will

prepare my athlete for the tests as required, but I would also like to

challenge this practice and suggest that they replace the test with more

specific rugby related tests.

My questions are this:

1. does this study have enough similarities with a rugby type situation to

be able to argue my point.

2. Are there many(any) similar studies for rugby.

3. What drills could one complete with some measure of repeatability that

compare to the Judo type drills that we can test perhaps they may be willing

to look at the testing and improve their testing protocols.

4. Have I missed the boat completely and 3km runs are the best test?

Oddly it seems that forwards in rugby need to have much better lactate

threshold than backs as well as greater strength. This is because while

forwards are scrumming, rucking and mauling the backs stand still waiting to

get the ball and run short duration sprints (says a former forward:). The

high intesity wrestling type movements of the forwards take significant

energy resources from players.

Any comments

*ABSTRACT* This study aimed to evaluate the viability to use Uchi-komi

(UK) in the evaluation of the judo endurance performance and using lactate

threshold the analysis of the blood lactate ([Lac]) and heart rate (HR)

determined through a lactate minimum test. The subjects were a group of 6

male, volunteer judokas, from 25.17 ± 5.76 years old, weight 84.50 ±

23.78kg and height

1.78 ± 0.10 m, competitors of different levels of performance (from regional

to international competitions) and match experience of (11 ± 6) years old.

Three tests were performed: a) 3000 m dash in track, the adapted test of

lactate minimum for running and c) for UK, with execution of the blow

ippon-seoi-nague. No significant difference was evident for the track tests

and UK in relation to blood lactate and heart rate (p > 0.05) (3.87 ± 0.38vs

4.17 ± 0.54 mmol·L-1 and 167 ± 2 vs 152 ± 7 b·min-1, respectively). In

conclusion it is stressed that: 1) The specific test for lactate minimum in

judo sport is a promising possibility of aerobic capacity evaluation and a

instrument of intensity training control; 2) The metabolic profile in Vlmand UK

lm is similar, because there are not differences in the [Lac] and in the HR

at this intensity; 3) It is possible to estimate the training intensity

through the determination of the lactate minimum intensity in running (Vlm)

and the Heart Rate associated (HR) from the execution of ippon-seoi- nague

(uchi-komi) in judo training; 4) The Vlm for judo athletes is approximately

88% of the V3000.
