We investigated the effects of leg stiffness on running speed, jump height and leg power in 13 male 2(nd)- and 3(rd)-series ranked tennis players (23 ± 3 years old, 73.2 ± 8.4 kg, 1.81 ± 0.06 m). Leg stiffness and jump height were assessed using jumping and hopping tests. Mean running speeds over 20 m and 40 m (speed₂₀ and speed₄₀, respectively) were(More)
The aim of this study was to evaluate the energy cost of speedway open-wheel race car driving using actimetry. Eight pilot students participated in a training session consisting of 5 successive bouts of around 30 minutes driving at steady speed on the Bugatti speedway of Le Mans (France). Energy expenditure (EE, kcal) was determined continuously by the(More)
Based on a theoretical approach from world record running data, we have previously calculated that the most suitable duration for measuring maximal aerobic velocity (Vamax) by a field test was 5 min (Vamax(5)). The aim of this study was, therefore, to check this hypothesis on 48 men of various levels of physical fitness by comparing (Vmax(5)) with (Vamax)(More)
BACKGROUND The sit-to-stand movement requires balance control and coordination between the trunk and lower limbs. For these reasons, it is commonly used in clinics for evaluating lower limb muscle function in the elderly. The aim of the present study was to point out re levant biomechanical and neurophysiological sit-to-stand parameters allowing comparison(More)
BACKGROUND Sit-to-stand (STS) movement is useful for evaluating lower limb muscle function, especially from force platforms. Nevertheless, due to a lack of standardization of the STS movement (e.g., position, subject's instructions, etc.), it is difficult to compare results obtained in previous studies. AIMS The aim of the present study was to determine(More)
