anaemia [23, 24] and where anaemia is likely to reduce the transport of oxygen [24], it are probable that a chronic
malaria can reduce the aerobic performance. Our subjects can thus be feeble when they are affected by the malaria.
Moreover, the study of Bongbele and al., (1998) [25] on the blood transport capacity in Congolese sportsmen high level,
apparently healthy, raises that this anaemia is haemolytic by nature [26], but can be also ferriprive.
Moreover, Schmidt and al., showed that the blood capacity of transport of O
2
depends, inter alia, of the infested
percentage of erythrocytes [24]. Moreover, so some of our subjects could be not infested, it is possible that those
suffered from other parasitoses or of deficiencies has minimum, being able to explain an anaemia. It is also probable that
they were also affected by the malaria, but in sufficiently tiny proportions to make a drop thick wrongfully negative [27].
However, several studies showed that the reduction of the rate of haemoglobin induced by the metabolic disturbances
caused by the malaria causes limitation of the maximum consumption of oxygen, by the means of a fall of the affinity of
haemoglobin [28]. It would be then suitable to determine the total number of erythrocytes, the concentration of
haemoglobin, average erythrocytaire volume, the hematocrite and the blood capacity of transport of oxygen. The second
limit is related to the generalization of the results to the whole of the judoists of Congo. Indeed, the power of a statistical
test being related to the sample size, the data obtained from our 14 judoists do not make it possible to draw the
generalizable conclusions to the young Congolese judoists. However, the principal forces of this work hold in several
points.
First of all, no study, to our knowledge, brings back in sub-Saharan Africa (ASS) results associated with the effects of a
drive in ''strength-velocity'' on the biochemical modifications in high level black judoists involved in full growth. Such is
the first force of the study. The second force resides in the use in ASS of spectroscopy IRTF to evaluate the immediately
induced biological modifications by this type of drive. Indeed, alternation at the time of the combat of judo of very short
actions (2 to 4 seconds), very intense (infra-maximum), proceeding during reduced spaces (tatamis of 16m x 16m) and
time of active recovery of variable durations (distributed according to the drawings of lots), characterizes the current
practice of the competitions of judo. If in the plan physiological and more particularly energy, the interaction of these
alternations were the subject of some studies [29, 30], it is on the other hand seldom the case of the variations of the
blood data immediately induced by this drive. Except the directly measurable variations of the lactatemy in the course of
competition and drive, we miss sufficient and reliable information in this field. This deficiency probably results from the
absence of tools and techniques adapted and directly usable on the ground. This explains the choice of spectrometry
IRTF to mitigate the lacks relating to it. In spectrophotometry close to the infra-red, this technique was recently used in a
noninvasive way in sport for, starting from haemoglobin, to study muscular oxygenation [16]. This work brings back
differences in concentration of glucose by the means of a significant increase during engagements in our judoists,
whatever 0the period of evaluation. Already Klassen and al., (1990) had observed from the very start of the combat of
judo, a free passage of glucose coming partly from the catabolism of muscular glycogen [31]. This very transitory
phenomenon can however explain only partially the significant increase of the glycemia observed, especially at the
beginning of the program (Δ = 26.1% of the value before the fight). It is probable that this one is primarily due to a
strong hepatic reactivity under the effect of catecholamines, in connection with the intensity of work. The variation of
definitely high glycemic concentration at the beginning of the program could result from a stronger hepatic, in particular
muscular production and would testify indirectly to the use of the emergency substrates which are the ATP-
phosphorylcréatine couple (PCr) and the muscular glycogen [32]. On the other hand, the reduction in the concentration
in serum glucose between the program and the end of the program could be the sign of a depletion of muscular the
glycogen reserves, synonymous with a beginning of tiredness and/or a food insufficiency in glucides. The recovery of
[Gl], as for it, is made conspicuous by a decrease with the waning of the combat, however faster at the end of the
program (-29.5%) that at the beginning of drive (-26.2%) and with semi-course of the training cycle (-5.4%). The strong
reduction observed during phases 3 and 1 of the program indicates a strong peripheral collecting, in particular muscular
that its hepatic production, probably resulting from a significant activation, especially from the GLUT-4 supported at the
same time by a weak muscular concentration and the presence of the insulin [33], itself allowed at the end of the
program by the fall of the intensity of the muscular activity. Compared to the variations of the concentrations out of
triglycerides and total fatty acids (tables 1 and 3), they show the same kinetics curiously as those of the glucose : (1)
mobilization of [TG] and [AGt)], during phases 1 and 2 of drive, with respective variations of : +11.5% versus +9.9%
for [TG], +12.5%
versus
+9.0% for [AGt] ; (2) inversion of the phenomenon during periods 2 and 3 : -14.8% for [TG]
and -2.0% for [AGt].
This study made it possible to measure the lactatemy in four situations. Firstly, at rest and at comparable age, [La] with
0.99±0.15 mmol/l in our judoists 1.03±0.40 mmol/l in the series of Saïgo amounts against, (2004) [34]. After heating,
the values of [La] of our subjects are respectively of 9.11±1.82 mmol/l before the first combat (beginning of the
program, 9.27±0.12 mmol/l with semi-course and 9.16±0.07 mmol/l at the end of the program, is an average of 9.51
mmol/l. Ba and al., (2012) bring back a lactatemy of 2.33±0.38 mmol/l in young old Senegalese judoists from 14 to 17
years [35]. On the other hand, Victorov and al. (2002) bring back 4.7±2.2 mmol/l at the practise of sambo (discipline
derived from the ju-jitsu, where the keys of neck and leg are allowed) [36]. These results show a disparity of the
lactatemy according to whether the activities solicit more the upper limbs or the lower limbs. Indeed, the meetings of
physical preparation differ from the muscular groups which they bring into play. Concerning our program of judo, the
