BACKGROUND & AIMS: To date, studies assessing the relationship between sarcopenia and delirium, two of the most common geriatric syndromes, are lacking. We sought to explore this association by investigating the co-occurrence of these two conditions and the independent association between them in a population of hospitalized older adults. METHODS: Cross-sectional multicenter analysis of older adults consecutively admitted to 12 acute geriatric units (AGUs). Sarcopenia was assessed upon admission by evaluating the presence of low skeletal mass index (kg/m(2)), and either low handgrip strength or low walking speed (European Working Group on Sarcopenia in Older People, EWGSOP criteria)...

BACKGROUND AND PURPOSE: Muscle weakness predisposes older adults to a fourfold increase in functional limitations and has previously been associated with reduced motor cortex excitability in aging adults. The purpose of this study was to determine whether a single session of anodal transcranial direct current stimulation (tDCS) of the motor cortex would increase elbow flexion muscle strength and electromyographic (EMG) amplitude in very old individuals. METHODS: Eleven very old individuals-85...

The study was aimed at determining the acute effects of two types of occlusal splints on maximum isometric strength and fatigue of the elbow flexors muscles. The hypothesis was that splint-induced masticatory muscle repositioning might improve primary muscles recruitment by stretching masticatory muscles especially with the thicker splint.On nine physically active volunteers with no temporo-mandibular joint and masticatory muscles disorders, we assessed maximum voluntary contraction (MVC) of the elbow flexors with diurnal (OSD, 1-mm thick) and sport (OSSP, 3-mm thick) splints, and without splint (control, Ctrl)...

OBJECTIVE: Exercise-induced muscle damage (EIMD) has been shown to reduce endurance exercise performance. This study examined the effects of EIMD on critical torque (CT) and the sum of the torque integral above CT during (∫ T total) during a 5-min all-out, intermittent isometric knee extension exercise. METHODS: CT was determined in eight participants prior to and 48-h following EIMD. EIMD was induced using electrically stimulated eccentric knee extensions until maximal voluntary strength (MVC) was reduced by 40%...

BACKGROUND: Medial knee collapse can signal an underlying movement issue that, if uncorrected, can lead to a variety of knee injuries. Placing a band around the distal thigh may act as a proprioceptive aid to minimize medial collapse of the knee during squats; however, little is known about EMG and biomechanics in trained and untrained individuals during the squat with an elastic band added. HYPOTHESIS/PURPOSE: To investigate the effects of the TheraBand® Band Loop on kinematics and muscle activity of the lower extremity during a standard barbell back squat at different intensities in both trained and untrained individuals...

BACKGROUND: Deficiency of survival motor neuron (SMN) protein, which is encoded by the SMN1 and SMN2 genes, induces widespread splicing defects mainly in spinal motor neurons, and leads to spinal muscular atrophy (SMA). Currently, there is no effective treatment for SMA. Liuwei dihuang (LWDH), a traditional Chinese herbal formula, possesses multiple therapeutic benefits against various diseases via modulation of the nervous, immune and endocrine systems. Previously, we demonstrated water extract of LWDH (LWDH-WE) protects dopaminergic neurons and improves motor activity in models of Parkinson's disease...

BACKGROUND: Hip adductor flexibility and strength is an important component of athletic performance and many activities of daily living. Little research has been done on the acute effects of a single session of stretching on hip abduction range of motion (ROM). OBJECTIVES: The aim of this study was to compare 3 clinical stretching procedures against passive static stretching and control on ROM and peak isometric maximal voluntary contraction (MVC). DESIGN: Using a randomized crossover study design, a total of 40 participants (20 male and 20 female) who had reduced hip adductor muscle length attended a familiarization session and 5 testing sessions on non-consecutive days...

OBJECTIVE: Although neural adaptations from strength training are known to occur, the acute responses associated with heavy-strength (HST) and hypertrophy training (HYT) remain unclear. Therefore, we aimed to compare the acute behaviour of corticospinal responses following a single session of HST vs HYT over a 72-h period. METHODS: Fourteen participants completed a random counterbalanced, crossover study that consisted of a single HST session [5 sets × 3 repetition maximum (RM)], a HYT session (3 sets × 12 RM) of the leg extensors and a control session (CON)...

After a fall without fracture an 83-year-old man who was treated with warfarin was admitted with severe groin pain on the left hip. A few days later he had reduced strength in hip flexion and knee extension, absent patellar tendon reflex, and decreased sensibility of the anterior thigh and the medial lower leg. A magnetic resonance imaging revealed a large haematoma in the left iliac muscle. Iliac haematoma-induced femoral nerve compression neuropathy is a rare condition but should be considered as a differential diagnosis for L4 root compression in patients, who are receiving anticoagulant therapy...

BACKGROUND: Muscle fatigue, a prominent symptom in older patients, can be assessed by sustained maximal handgrip testing. The force decline during sustained maximal contraction is described for young adults, but data for elderly persons are scarce. The aim of this study was to investigate force-time characteristics during a sustained maximal handgrip effort according to age and clinical condition. METHODS AND MATERIALS: Force-time data were continuously recorded during sustained maximal grip effort in 91 elderly patients (aged 83±5years), 100 elderly controls (aged 74±5years) and 100 young controls (aged 23±3years)...

REVIEW
Thierry Paillard
Although motor output of the postural function clearly influences postural performance in young and older subjects, no relationship has been formally established between them. However, the relationship between lower-extremity muscle strength/power and postural performance is often pointed out, especially in older subjects. In fact, the influence of motor output may vary according to the postural condition considered (e.g., static, dynamic, challenging, disturbing). In static postural condition, there may be a relationship between lower-extremity muscle strength and postural performance when the value of muscle strength is below a certain threshold in older subjects...

Sports analytics is best known as the field of research that focuses on discovering slight but significant improvements within competitions; however, broader sets of athlete- and team-level data from outside of competitions (e.g., strength and conditioning metrics) have been typically left out from such analyses. Given that strength and conditioning programs are perhaps the most common avenue through which people expect extra-competition progress to translate into within-competition performance, it is clear that strength and conditioning metrics warrant closer analytic attention...

Many fishes perform quick and sudden swimming maneuvers known as fast-starts to escape when threatened. In pulse-type weakly electric fishes these responses are accompanied by transient increases in the rate of electric signal production known as novelty responses. While novelty responses may increase an individual's information about their surroundings, they are aerobically powered and may come at a high energetic cost when compared to fast-starts, which rely primarily on anaerobic muscle. The juxtaposition between two key aspects of fast-starts in these fishes - the aerobic novelty response and the anaerobic swimming performance - makes them an interesting model for studying effects of hypoxia on escape performance and sensory information acquisition...

Gregory S Walsh
BACKGROUND: The importance of warm up procedures prior to athletic performance is well established. A common component of such procedures is muscle stretching. There is conflicting evidence regarding the effect of static stretching (SS) as part of warm up procedures on knee joint position sense (KJPS) and the effect of dynamic stretching (DS) on KJPS is currently unknown. The aim of this study was to determine the effect of dynamic and static stretching as part warm up procedures on KJPS and knee extension and flexion strength...
