Reliability of a standing isokinetic shoulder rotators strength test using a functional electromechanical dynamometer: effects of velocity [PDF]

PeerJ, 2020
Background The evaluation of the force in internal rotation (IR) and external rotation (ER) of the shoulder is commonly used to diagnose possible pathologies or disorders in the glenohumeral joint and to assess patient’s status and progression over time.

Erythrocyte nicotinamide adenine dinucleotide concentration is enhanced by systematic sports participation

BMC Sports Science, Medicine and Rehabilitation
Background Nicotinamide adenine dinucleotide (NAD+), nicotinamide adenine dinucleotide phosphate (NADP+), and their reduced forms (NADH and NADPH) are the vital cofactors for most cellular oxidation/reduction reactions and therefore influence most ...

Subjective assessment and biochemical evaluation of traction therapy in women with chronic low back pain: does body mass index matter? A clinical study

BMC Musculoskeletal Disorders, 2023
Background Apart from the positive effect of lumbar traction on structural changes within the spine in patients with low back pain, it is likely that therapeutic effects are correlated with pain biomarkers in the blood.

Effect of Power Output and Pedaling Cadence on Plantar Pressures in Professional Cyclists with Overuse Injuries

Sports
Background: Plantar pressure analysis provides insight into load distribution at the foot–pedal interface during cycling; however, its modulation by pedaling power, cadence, and overuse injury status remains poorly understood by professional cyclists. It

Effect of a 3-month L-carnitine supplementation and resistance training program on circulating markers and bone mineral density in postmenopausal women: a randomized controlled trial

Nutrition & Metabolism, 2023
Background Higher circulating levels of trimethylamine N-oxide (TMAO), which is a metabolite that can be produced by the gut microbiota from L-carnitine (LC), have been associated with bone mineral density (BMD).

Kinetic analysis of change of direction simulating a defensive action in soccer players with and without acute fatigue

Heliyon
The objective of this study is to analyse the kinetic effects of acute fatigue during a 45° change of direction executed with the non-dominant limb, emulating a typical defensive action during pressing in soccer.
