The aims of this study were to use a specific all-out 30-sec tethered test to determine the anaerobic parameters in elite kayakers and verify the relationship between these results and sports performance. Twelve elite slalom kayakers were evaluated. The tethered canoe system was created and used for the all-out 30-sec test application. Measurements of peak force, mean force, minimum force, fatigue index and impulse were performed. Performance evaluation was determined by measuring the time of race in a simulated race containing 24 gates on a white-water course. Blood was collected (25-µl) for analysis of lactate concentration at rest and at 2, 4, 6, 8 and 10-min intervals after both the all-out test and the simulated race. The Pearson product moment correlation shows a inverse and significant relationship of peak force, mean force and impulse with time of race. Blood lactate concentrations after the all-out test and the simulated race peak at same time (4 min). Additionally, no interaction was visualized between time and all-out test/simulated race for blood lactate concentrations (P <0.365). These results suggest a relationship between the parameters of the all-out test and performance. Thus, the tethered canoe system is a useful tool for determining parameters that could be used in training control of slalom kayakers.

Plasma nitrate (NO) and nitrite (NO) increase in a dose-dependent manner following NO ingestion. To explore if the same dose-response relationship applies to other nitric oxide (NO) congeners in different blood compartments and skeletal muscle, as well as the subsequent physiological responses, we provided 11 healthy participants with NO depleted beetroot juice (placebo), and beetroot juice (BR) containing 6.4, 12.

This study evaluated the influence of cycle computers on the accuracy of power and cadence data. The research was divided into three phases: (1) a graded exercise test (GXT) at different constant loads to record power and cadence data; (2) a self-paced effort lasting 1 min to measure mean maximal power output (MMP); and (3) a short all-out effort. Eight cyclists completed the GXT, ten participated in the 1-min test, and thirty participated in the sprint effort.

Twenty-four girls and fourteen boys aged 12-13 participated in the study. The movement of the hip rim was analyzed using a specialized inertial device equipped with a triaxial gyroscope and accelerometer to measure changes in angular velocity and acceleration.

We tested the hypothesis that power at maximal metabolic steady state is similar between fitness matched men and women. Eighteen participants (9 men, 9 women) performed a cycling graded exercise test for maximal oxygen consumption (V̇O). Men and women were matched for V̇O normalized to fat free mass (FFM), which was 50.
