BACKGROUND: Effects of endurance training on adipose insulin sensitivity in association with body composition, circulating adipokines, and markers of inflammation have been studied less in young Asian subjects. METHODS: Adipose insulin sensitivity/resistance was compared between 170 female Japanese collegiate athletes and 311 nonathletes (18-24 years), who underwent measurements of serum adipokines, markers of insulin sensitivity, inflammation, and dual-energy X-ray absorptiometry...

Rapid and accurate diagnosis of malaria is the need of hour for effective management and controlling drug resistance. The conventional and gold-standard method, Light microscopy (LM), is time-consuming, requires trained staff and well-maintained equipments. The newly developed, rapid diagnostic tests (RDT) are fast and reliable, but give only qualitative results, are expensive and have short shelf life. Light Emission Diode fluorescence microscopy (LED FM) may provide a reliable alternative which can be used for routine diagnosis...

BACKGROUND: The purpose of this study was to compare the effects of high and low velocity knee extension training on changes in muscle strength and mobility status in high-functioning older adults. METHODS: Twenty-six (16 female, 10 male) older adults (mean age of 65) were randomized to either 6weeks of low velocity resistance training (LVRT) performed at 75°/s or high velocity resistance training (HVRT) performed at 240°/s. Both groups performed 3 sets of knee extension exercises at maximal effort, 3 times a week...

As in most sensory systems electrosensory images in weakly electric fish are encoded in two parallel pathways, fast and slow. From the work on wave type electric fish these pathways are thought to encode the time and amplitude of electrosensory signals respectively. This article focuses on the primary afferents giving origin to the slow path of the pulse type weakly electric fish Gymnotus omarorum We found that burst duration coders respond with a high-frequency train of spikes to each electric organ discharge...

Similar to muscles, the intestine is also insulin resistant in obese subjects and subjects with impaired glucose tolerance. Exercise training improves muscle insulin sensitivity, but its effects on intestinal metabolism are not known. We studied the effects of high intensity interval training (HIIT) and moderate intensity continuous training (MICT) on intestinal glucose and free fatty acid uptake from circulation in humans. Twenty-eight healthy middle-aged sedentary men were randomized for two weeks of HIIT or MICT...

Due to changes in life style, obesity and obesity related complication such as insulin resistance, type 2 diabetes and non-alcoholic fatty liver disease caused worldwide health problems. Regular exercise has been frequently prescribed to combat metabolic complication of obesity but its molecular mechanism has not been fully illustrated. We investigated molecular mechanism of lipid lowering effect of exercise training in high fat diet fed mice by focusing on miR-33 expression and autophagy pathway. 24 mice were assigned to normal chow (NC) (n=8), high-fat diet (HFD) (n=16) group and subjected to NC and HFD for 13-weeks...

AIMS/HYPOTHESIS: Our aim was to investigate the effects and prevalence of non-responders (NR) to high-intensity interval training (HIIT) and resistant training (RT)in adult woman with insulin resistance on cardiometabolic health parameters. METHODS: Sedentary overweight/obese insulin resistant adult women (age = 33.5 ±6.5 years;BMI=29.9 ± 3.7kg/m2) were randomly assigned to a tri-weekly HIIT program(HIIT;n=18) or resistant training (RT;n=17).Anthropometry (body mass, fat mas, muscle mass, waist circumference and skinfolds thickness),cardiovascular(blood pressure), metabolic (fasting glucose, fasting insulin and HOMA-IR),as well muscle strength, and endurance performance co-variables were measured before and after 12 weeks in both intervention groups...

Eccentric overload is used to enhance performance. The purpose of this study was to investigate the acute effects of eccentric overload on concentric front squat performance. Twenty resistance-trained males (age=23.80±1.82yrs, ht=176.95±5.21cm, mass=83.49±10.43kg, 1 Repetition Maximum [1RM] front squat=131.02±21.32kg) volunteered. A dynamic warm-up and warm-up sets of front squat were performed. Eccentric hooks were added to the barbell. They descended for 3 seconds, until eccentric hooks released, and performed the concentric phase as fast as possible...

PURPOSE: The aim of the present study was to investigate the effect and time course of high-frequent low-load resistance training with blood-flow restriction (BFR) on rapid force capacity (i.e. rate of torque development (RTD)). METHODS: Ten male subjects (22.8±2.3 years) performed four sets of knee extensor exercise (20%1RM) to concentric failure during concurrent BFR of the thigh (100mmHg), while eight work-matched controls (21.9±3.0 years) trained without BFR (CON)...

Acute responses of motor units were investigated during submaximal voluntary isometric tasks following eccentric overload (EO) and constant load (CL) knee extension resistance exercise. Ten healthy resistance-trained participants performed four experimental test sessions separated by 5 days over a 20 day period. Two sessions involved constant load and the other two used eccentric overload. EO and CL used both sessions for different target knee eccentric extension phases; one at 2 sec and the other at 4 sec...

BACKGROUND: Movement velocity is an acute resistance-training variable that can be manipulated to potentially optimize dynamic muscular strength development. However, it is unclear whether performing faster or slower repetitions actually influences dynamic muscular strength gains. OBJECTIVE: We conducted a systematic review and meta-analysis to examine the effect of movement velocity during resistance training on dynamic muscular strength. METHODS: Five electronic databases were searched using terms related to movement velocity and resistance training...

BACKGROUND: The purpose of this study was to examine whether ingesting a pre-workout dietary supplement (PWS) with and without synephrine (S) during training affects training responses in resistance-trained males. METHODS: Resistance-trained males (N = 80) were randomly assigned to supplement their diet in a double-blind manner with either a flavored placebo (PLA); a PWS containing beta-alanine (3 g), creatine nitrate as a salt (2 g), arginine alpha-ketoglutarate (2 g), N-Acetyl-L-Tyrosine (300 mg), caffeine (284 mg), Mucuna pruiriens extract standardized for 15% L-Dopa (15 mg), Vitamin C as Ascorbic Acid (500 mg), niacin (60 mg), folate as folic acid (50 mg), and Vitamin B12 as Methylcobalamin (70 mg); or, the PWS supplement with Citrus aurantium extract containing 20 mg of synephrine (PWS + S) once per day for 8-weeks during training...

Obesity and metabolic syndrome is a worldwide pandemic and associated with high cardiovascular risk. Metabolic endotoxemia (ME) is thought to be an underlying molecular mechanism. It triggers toll-like receptor 4-mediated inflammatory adipokines and causes a chronic low grade inflammatory status, which results in cardiovascular risk increase. Exercise is the best nonpharmacological treatment to improve prognosis. In this study, we examined the circulating endotoxin level in Korean obese women and investigated effects of exercise on it...

Exercise is an effective intervention for prevention and treatment of type 2 diabetes. Skeletal muscle combines multiple signals contributing to the beneficial effects of exercise on cardiometabolic health. Inorganic nitrate increases exercise efficiency, tolerance and performance. The transcriptional regulator peroxisome proliferator-activated receptorγ coactivator1α (PGC1α) coordinates the exercise-stimulated skeletal muscle fiber-type switch from glycolytic fast-twitch (type IIb) to oxidative slow-twitch (type I) and intermediate (type IIa) fibers; an effect reversed in insulin resistance and diabetes...

Adequate protein intake and resistance training are effective strategies to maintain muscle mass, but the effect of their combination on metabolic profile during weight loss remains to be determined in older adults. The main objective of this study was to determine the effect of a 16-week high-protein caloric restriction combined with resistance training on chronic disease risk factors in obese older individuals with metabolic impairments. A total of 26 overweight adults aged between 60 and 75 years (BMI 32...
