The existing publications on biomechanics of weight lifting tend to concentrate on injury prevention or performance evaluation through various kinetic or kinematic evaluation of the athletes (GAR98, CAR04). An analytical model could prove effective in an individualized approach to performance enhancement. The athlete can be represented by a planar 6 degrees of freedom robotic manipulator where ...

Methods Twelve recreationally active men, 28.5 ± 5 years of age and 197.1 ± 32.4 pounds body weight, took part in this double-blind, placebo-controlled trial on a volitional basis. Study participants were randomly assigned to receive either Adenoflex (AD) or Placebo (PL) for a 14 day period and were directed to take two servings per day for the first 8 days (immediately after training and five ...

The aim of this study was to evaluate the effectiveness of free-weight and machine-based exercises to increase different strength and speed-strength variables. One hundred twenty male participants (age: 23.8 ± 2.5 years; body height: 181.0 ± 6.8 cm; body mass: 80.2 ± 8.9 kg) joined the study. The 2 experimental groups completed an 8 week periodized strength training program that included 2 trai...

This study examined the levels of hip and knee torques produced during a one repetition maximum (1RM partial) squat and full squat in order to determine if there would be a difference in the peak torque created at the two depths. Eight male athletes (standing height = 1.84  0.07 m; mass = 87  14 kg; age 23 ± 2.1 years) volunteered for the study. Each subject performed a 1RM squat at full squa...

In order to reduce the amplitude of bench press, athletes use a specific technical element "arch", which involves significant bending back. The "arch" allows indicators mechanical work, amount applied force, trajectory vertical movement bar and distance travelled by bar. problem using an extremely high press arch during is important task modern sports practice. goal study ways objectifying rule...
