Backseat Inclination Affects the Myoelectric Activation During the Inclined Leg Press Exercise in Recreationally Trained Men.

Marchetti, PH, Gomes, WA, Da Silva, JJ, Magalhaes, RA, Teixeira, LFM, and Whiting, WC. Backseat inclination affects the myoelectric activation during the inclined leg press exercise in recreationally trained men. J Strength Cond Res 37(10): e541-e545, 2023-Changes in the angle between the seat and backrest during the inclined leg press (ILP) exercise may influence myoelectric activity.

Centre of mass kinematics of the hammer and thrower during different hammer-throwing drills utilised for training.

During elite-level hammer throws, the vertical displacement of the centre of mass (COM) of the thrower and hammer are approximately 180° out of phase (the hammer's COM is at its high point when the thrower's COM is at its low point, and vice versa) prior to the hammer's release. This out-of-phase coordination pattern contributes to the velocity of the hammer, which ultimately contributes to the distance thrown. Several drills are used to improve coordination between the thrower's and hammer's COM, but it is not currently known if the out-of-phase pattern is present during these drills.

Different Knee and Ankle Positions Affect Force and Muscle Activation During Prone Leg Curl in Trained Subjects.

Marchetti, PH, Magalhaes, RA, Gomes, WA, da Silva, JJ, Stecyk, SD, and Whiting, WC. Different knee and ankle positions affect force and muscle activation during prone leg curl in trained subjects. J Strength Cond Res 35(12): 3322-3326, 2021-Different joint positions for biarticular muscles may affect force and muscular activity during single-joint exercises.

Nortriptyline Abuse: A Case Report and Review of the Literature.

The tricyclic antidepressants have long been a tool in the physician's armament for numerous indications, the most prominent of which being depression. Although their efficacy and side effects have been well documented, less known is their abuse. Prior literature has discussed this more for the tertiary amines such as amitriptyline, but currently, there are no documented cases of abuse with the secondary amine nortriptyline.

Treatment of Depression With Duloxetine in Mitochondrial Encephalopathy, Lactic Acidosis, and Stroke-Like Episodes.

The mitochondrial cytopathies are a heterogeneous group of diseases characterized by heteroplasmic maternal transmission and selective dysfunction of tissues and organs highly dependent on aerobic respiration (eg, skeletal muscle, cardiac muscle, and brain). Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) is a specific subtype of mitochondrial cytopathy that is commonly associated with mood disturbances in individuals who survive until adulthood. Because of the altered cellular metabolism inherent in MELAS, it is often difficult to determine drug dosing, drug choice, and treatment response in patients with this rare disease.

Muscle activation patterns while lifting stable and unstable loads on stable and unstable surfaces.

In an attempt to mimic everyday activities that are performed in 3-dimensional environments, exercise programs have been designed to integrate training of the trunk muscles with training of the extremities. Many believe that the most effective way to recruit the core stabilizing muscles is to execute traditional exercise movements on unstable surfaces. However, physical activity is rarely performed with a stable load on an unstable surface; usually, the surface is stable, and the external resistance is not.

Effectiveness of collision-involved motorcycle helmets in Thailand.

The purpose of this study was to analyze variables present in selected motorcycle crashes involving helmeted riders to find the best injury predictors. The helmets used in this study were collected from motorcycle crashes in Thailand. Pertinent data were collected, a conventional helmet impact drop test apparatus was used to quantify the head impact forces, and stepwise multiple regression analyses were performed.
