“…To our knowledge, no study has reported power averaged for a single contact period during sprint running. Further, F max and V max were also consistent with values reported in previous studies (Cheetham et al, 1985;Jaskolska et al, 1999a;Jaskolski et al, 1996). These measurements of P max showed a high reproducibility, and could be performed during one single sprint, since P max and F-V relationships did not differ significantly when subjects ran against their default load vs. against a higher or lower load, or when taking all these conditions into account.…”

“…Power output is then measured as the product of the treadmill belt velocity and the horizontal component of the force exerted on the tether, measured by force transducers and goniometers. These treadmills are either non-motorized (Belli and Lacour, 1989;Cheetham et al, 1985;Funato et al, 2001;Lakomy, 1987;Nevill et al, 1989) or motorized (Chelly and Denis, 2001;Falk et al, 1996;Jaskolska et al, 1999b;Jaskolski et al, 1996) and in this case, the default motor torque is set to compensate for the friction of the treadmill belt-bed due to subjects' body weight.…”

“…Furthermore, in endurance-trained male children (11 ± 13 yrs), AerT GE was reported to occur at very high relative intensities, i.e.,~80 % V Ç O 2max [147]. This might indicate a less well-developed acidosis tolerance in the young [39,157] ± particularly marked after predominantly aerobic endurance training ± which can lead to comparably lower maximal lactate concentrations [26].…”

A Conceptual Framework for Performance Diagnosis and Training Prescription from Submaximal Gas Exchange Parameters - Theory and Application

The first part of this article intends to give an applicable framework for the evaluation of endurance capacity as well as for the derivation of exercise prescription by the use of two gas exchange thresholds: aerobic (AerTGE) and anaerobic (AnTGE). AerT GE corresponds to the first increase in blood lactate during incremental exercise whereas AnTGE approximates the maximal lactate steady state. With very few constraints, they are valid in competitive athletes, sedentary subjects, and patients. In the second part of the paper, the practical application of gas exchange thresholds in cross-sectional and longitudinal studies is described, thereby further validating the 2-threshold model. It is shown that AerTGE and AnTGE can reliably distinguish between different states of endurance capacity and that they can well detect training-induced changes. Factors influencing their relationship to the maximal oxygen uptake are discussed. Finally, some approaches of using gas exchange thresholds for exercise prescription in athletes, healthy subjects, and chronically diseased patients are addressed.

“…Such short duration, but high intensity, tests are used widely, not only to establish a subject's characteristic indices of power generation (e.g. peak and 30 s mean values), but also as a means of investigating aspects of tissue metabolic control (Boobis, Williams & Wootton, 1982;Jacobs, Tesch, Bar-Or, Karlsson & Dotan, 1983;Cheetham, Williams & Lakomy, 1985) and pulmonary gas exchange (Katch, 1973;Lamarra, Whipp, Ward & Wasserman, 1987).…”

SUMMARYThis study assessed blood flow in the common femoral, superficial femoral and profunda femoris arteries, the effects of vasodilator metabolites and changes in blood pressure and pulse during recovery after high intensity exercise (Wingate test). Mean common femoral artery flow increased sevenfold in response to the exercise. The subsequent decline in mean common femoral artery flow was mono-exponential with a mean time constant of 19 min. The post-exercise increase in profunda femoris artery flow (ninefold) was significantly greater than the superficial femoral artery flow (fourfold, P < 0.05). Systolic blood pressure and heart rate decreased monotonically throughout recovery. In contrast, diastolic blood pressure showed a significant fCll below batseline at 3 min (P < 0 05) with a return to baseline at 60 min. The greatest drop below baseline (approximately 20 mmHg) occurred around 7 min. Lactate reached a maximum of 13 6 + 2 3 mmol 1 at 8 min (P < 0.05) and was still significantly above baseline at 60 min. pH remained below 7-2 until 20 min of recovery. The results demonstrate that following high intensity exercise, blood flow to the limbs appears to be controlled by complex interactions of various vaso-active metabolites, each contributing proportionally more at different times during recovery.
