Although side-to-side asymmetry of the shoulder rotators calculated by independent peak torque (IPT) has been used for interpretation of injury risks in athletes, it may not measure strength through the entire range of motion (ROM) tested. The aim of this study was to compare side-to-side asymmetry of the shoulder rotators between independent peak torque (IPT) and ten-degree angle specific torq...

CONTEXT The use of isokinetic dynamometers playing an important role in different settings of sports and medicine. Therefore, a high reliability of these devices is required. OBJECTIVE The aim of this study was to examine the inter-session reliability of the dynamometer BTE PrimusRS regarding to the isolated single-joint exercises extension / flexion of the knee and elbow for isokinetic testi...

Objectives: To evaluate ultrasound’s effectiveness after eccentric-exercise-induced muscle damage. Participants: 22 subjects. Intervention: Random assignment to ultrasound (UT) or placebo (PT). Ultrasound was applied immediately and 24, 48, and 72 h after 50 maximum eccentric contractions of the biceps. Outcome Measures: Concentric and eccentric peak torques, resting elbow angle, and subjective...

The aim of this study was to evaluate and compare acute effects of a reciprocal action protocol and a super-set protocol on knee extensor performance during concentric isokinetic exercise. Fourteen men aged 29.4 ± 6.1 years were tested on three different protocols, with 1 min of rest between sets: control (3 sets of 10 isokinetic knee extension repetitions), reciprocal action protocol (3 sets o...

In this study the torque output of intermittently stimulated paralyzed human knee extensor muscles during imposed isokinetic cyclical lower leg movements was investigated in four paraplegic subjects. During prolonged (10 min) experiments the influence of knee angular velocity and stimulation parameters on fatigue-induced torque decline was studied. Pulse width and amplitude were set to obtain m...

It is thought that time to peak torque and joint angle at parameters provide important data for the functional evaluation of quadriceps hamstring muscles. known studies with these are rare in literature. The aim this study investigate relationship between hamstring/quadriceps (H/Q) ratio, female football players. sample group consisted 20 footballers performing national women's league (3rd Divi...

OBJECTIVE To assess knee flexor-extensor muscular strength in elderly women with no previous history of musculoskeletal disorders on the lower limbs using an isokinetic dynamometer, in order to obtain data that could be used as a comparative parameter in the evaluation of elderly women with knee disorders, thus facilitating a better rehabilitation of these patients. METHODS Twenty-six volunte...

We tested whether explosive resistance training with partial range of motion (ROM) would be as effective full ROM using a noninferiority trial design. Fifteen subjects strength experience took part in an explosive—concentric only—leg press program, three times per week for 10 weeks. One leg was randomly assigned to exercise (ie, 9º) and the other ROM. Before after training, we assessed performa...

BACKGROUND Nicotine use amongst athletes is high and increasing, especially team sports, yet the limited previous studies investigating the performance consequences of this behaviour have not examined the effects of the principal active ingredient, nicotine, per se. Therefore, we determined whether nicotine gum affected muscular and anaerobic performance. METHODS Nine active males (24 ± 3 yea...
