Maximal tolerated power (MTP), peak values of oxygen uptake (VO2peak) and heart rate (HRpeak), anaerobic threshold (VT1) were determined during an incremental cycling exercise test before and after training periods. TL, quantified using the session rating of perceived exertion, did not differ between both modalities (CT: 4 438±572 vs. AT: 4 346±592 AU, p=0.300). Improvements in VO2peak were larger after CT (+36.4±24.7% of pre-training VO2peak, i. e., +4.4±2.3 mL.min-1.kg-1, n=14) than observed after AT (+20.1±9.1% of pre-training VO2peak, i. e., +2.6±1.0 mL.min-1.kg-1, n=12) (p=0.014). Additionally, CT significantly improved power (54.6±23.8 vs. 75.1±21.2 watts, p=0.001) and VO2 associated at VT1 (VO2: 9.8±2.5 vs. 12.6±2.9 mL.min-1.kg-1, p=0.001). This might be taken into account when prescribing exercise rehabilitation for CHD patients with different initial clinical limitations.

Methods Eleven well-trained cyclists completed a 70-s all-out cycling effort, in double-blind trials, after oral ingestion of either 0.3 g kg of sodium bicarbonate (NaHCO3) or 0.2 g kg body mass of calcium carbonate (PLA). Blood samples were taken to assess changes in acid–base balance before the start of the supramaximal exercise, and 0, 5 and 8 min after the exercise; ventilatory parameters were also measured at rest and during the SXT. Results At the end of the PLA trial, which induced mild acidosis (blood pH = 7.20), subjects presented a significant decrease in V̇ O2 (P < 0.05), which was related to the Communicated by Carsten Lundby. * Claire Thomas claire.thomas@univ-evry.fr 1 French National Institute of Sports (INSEP), 11 Tremblay Avenue, 75012 Paris, France 2 STAPS Department, University of Evry Val d’Essonne, François Mitterrand Boulevard, 91025 Evry, France 3 Institute of Sport, Exercise and Active Living (ISEAL), College of Sport and Exercise Science, Victoria University, Melbourne, Australia 4 EuroMov: Movement to Health, University of Montpellier, Montpellier, France amplitude of the decrease in minute ventilation (V̇E) during the SXT (r = 0.70, P < 0.01, n = 11). Pre-exercise metabolic alkalosis significantly prevented the exercise-induced decrease in V̇ O2 in eleven well-trained participants (PLA: 12.5 ± 2.1 % and ALK: 4.9 ± 0.9 %, P < 0.05) and the decrease in mean power output was significantly less pronounced in ALK (P < 0.05). Changes in the V̇ O2 decrease between PLA and ALK trials were positively related to changes in the V̇E decrease (r = 0.74, P < 0.001), but not to changes in power output (P > 0.05). Conclusions Pre-exercise alkalosis counteracted the V̇ O2 decrease related to mild acidosis, potentially as a result of changes in V̇E and in muscle acid–base status during the all-out supramaximal exercise.

A hundred and 81 soccer players from the region of Athens (age 23.4 ± 5.0 yrs, body mass 73.4 ± 7.7 kg, height 180.0 ± 5.9 cm, body fat (BF) 14.4 ± 3.6%), classified into quartiles according to 20 m sprint time (group A, 2.84-3.03 s; group B, 3.04-3.09 s; group C, 3.10-3.18 s; group D, 3.19-3.61 s), participated. Soccer players in group A were younger and had better performance in vertical jumps and in the Wingate anaerobic test (WAnT, p < 0.05). Sprint time correlated to age (r = 0.27), body mass (r = 0.23), body height (r = 0.20), BF (r = 0.23), vertical jumps (-0.58 ≤ r ≤ -0.50) and the WAnT (-0.45 ≤ r ≤ -0.30, p < 0.05). In summary, the magnitude of correlations of sprint time with measures of lower limbs muscle strength and power (WAnT and jumps) was larger than with anthropometric measures (body mass and BF).

TL model related performance at a specific time to the initial performance level and the superimposition of residual training effects. However, in team sport, the calendar of competitions imposed multi peak performances during the season. Additionally, physiological and model responses did not increase linearly with training load. If TL model was used to evaluate the effects of training strategies, in order to provide sufficient training stimuli to help highly qualified team sport athletes to progress and predict the physical performance, we argued that the respective time course of the physiological responses must be considered in elite team sport players when discussing performance changes that occur with training session interaction.

Concept of successful ageing is in first line on a preventive approach of care for older people. Promotion of regular physical activity is one of the main non-pharmaceutical measures proposed to older subjects as low rate of physical activity is frequently noticed in this age group. Moderate but regular physical activity is associated with a reduction in total mortality among older people, a positive effect on primary prevention of coronary heart disease and a significant benefit on the lipid profile. Improving body composition with a reduction in fat mass, reducing blood pressure and prevention of stroke, as well as type 2 diabetes, are also well established. Prevention of some cancers (especially that of breast and colon), increasing bone density and prevention of falls are also reported. Moreover, some longitudinal studies suggest that physical activity is linked to a reduced risk of developing dementia and Alzheimer's disease in particular.
