The single leg squat and single leg step down are two commonly used functional tasks to assess movement patterns. It is unknown how kinematics compare between these tasks. The purpose of this study was to identify kinematic differences in the lower extremity, pelvis and trunk between the single leg squat and the step down. Fourteen healthy individuals participated in this research and performed...

This paper presents a method for generating a whole-body squat motion for humanoid robot HRP-4 from human motion data. We convert joint angle trajectories into linear combination of base functions which are cubic B splines. In order to take into account the interactions with the environment and the stability conditions, we added appropriate kinematics constraints to the trajectory optimization ...

The specific aim of this study was to quantify muscle activity while performing squat with technique variations. Eight healthy volunteers performed squats under 5 types of foot positions: neutral position, under a 10o descending wedge, under a 10o ascending wedge, under a 10o medial wedge and under a 10o lateral wedge. It was evaluated electromyographic data of vastus medialis oblique, vastus l...

Six species of squat lobsters from a cold seep field in the northeastern South China Sea are studied. Two new species, Uroptychus jiaolongae n. sp. and U. spinulosus n. sp., are described, and their distinctions from the related species are detailed. Two species, Munidopsis tuberosa Osawa, Lin & Chan, 2008 and M. verrilli Benedict, 1902, are herein reported for the first time from a cold seep/h...

Muscle strength and power are important requirements in many sports. The correlation of jumping performance as manifestation muscle squatting one-repetition maximum (1RM) has been shown several investigations. Correlations with force a linear isokinetic leg press still pending. Since different testing devices produce relationships rotational measurements show conflicting results, further eviden...

purpose the purpose of this study was to describe the body structure and morphological characteristics of tunisian elite handball players, and to determine the effect of these variables on functional and physical performance levels. methods a sample of 42 male handball players (mean age 21.98±3.24 years; training duration 12 years) at international level was submitted to a test battery comprisi...

BACKGROUND The purpose of this study was to examine the efficacy of 15 days of betaine supplementation on muscle endurance, power performance and rate of fatigue in active college-aged men. METHODS Twenty-four male subjects were randomly assigned to one of two groups. The first group (BET; 20.4 +/- 1.3 years; height: 176.8 +/- 6.6 cm; body mass: 77.8 +/- 13.4 kg) consumed the supplement daily...
