Creatine (CR) and sodium bicarbonate (SB) alone improve anaerobic performance. However, the ergogenic effects of CR SB co-ingestion on taekwondo performance remains unknown. Forty trained athletes (21 ± 1 y.; 180.5 7.3 cm; 72.7 8.6 kg) were randomized to: (i) (CR + SB; 20 g CR+ 0.5 g·kg− 1·d− SB), (ii) CR, (iii) SB, (iv) placebo (PLA), or (v) control (CON) for 5 days. Before after supplementation, participants completed 3 bouts a Taekwondo Anaerobic Intermittent Kick Test (TAIKT) to...
Caffeine is widely consumed among elite athletes for its well-known ergogenic properties, and ability to increase exercise performance. However, studies date have predominantly focused on the anhydrous form of caffeine in male participants. The aim study was investigate effect caffeinated coffee ingestion lower-upper body muscular endurance, cognitive performance, heart rate variability (HRV) female athletes. A total 17 participants (mean ± standard deviation (SD): age = 23 2 years, mass 64...
Background The ergogenic properties of acute caffeine (CAF) and sodium bicarbonate (NaHCO3) ingestion on athletic performance have been previously investigated. However, each sport has unique physiological technical characteristics which warrants optimizing supplementations strategies for maximizing performance. This study examined the effects CAF NaHCO3 responses rate perceived exertion during a Karate-specific aerobic test (KSAT) in competitive karatekas.Methods In double-blind, crossover,...
Beetroot juice (BJ) and caffeine (CAF) are considered as ergogenic aids among athletes to enhance performance, however, the effects of BJ CAF co-ingestion unclear during team-sport-specific performance. This study aimed investigate acute on compared with placebo (PL), BJ, alone.Sixteen semi-professional male soccer players (age: 19.8 ± 2.2 years, body mass: 69.2 6.1 kg, height: 177.3 6.0 cm) completed four experimental trials using a randomized, double-blind design: + CAF, PL, PL PL....
To examine the effects of varying doses caffeine on autonomic reactivation following anaerobic exercise. Recreationally active males (N = 20; 24 ± 2y) participated in a randomized, double-blind, placebo-controlled, crossover study where participants ingested: [1] Control (CON; no supplement), [2] non-caffeinated placebo (PLA), [3] 3-mg∙kg− 1 (CAF3) or [4] 6-mg∙kg− (CAF6) prior to Wingate testing. Parasympathetic (lnRMSSD, primary outcome) and global HRV (lnSDNN, secondary were assessed at...
Studies have shown that nitrate (NO3−)-rich beetroot juice (BJ) supplementation improves endurance and high-intensity intermittent exercise. The dose–response effects on taekwondo following BJ are yet to be determined. This study aimed investigate two acute doses of 400 mg NO3− (BJ-400) 800 (BJ-800) taekwondo-specific performance cognitive function tests compared with a placebo (PL) control (CON) conditions. Eight trained male athletes (age: 20 ± 4 years, height: 180 2 cm, body mass: 64.8...
Background Carbohydrate (CHO) ingestion enhances exercise performance; however, the efficacy of CHO intake on repeated bouts simulating a taekwondo tournament is unknown. Therefore, purpose was to compare effects two different doses sports-specific kicking test during simulated compared placebo (PLA).Methods In double-blind, randomized-placebo controlled, cross-over trial, eleven junior male professional athletes (age: 16 ± 0.8 years, body mass: 55.3 7.3 kg) ingested one three solutions: (i)...
Muscle carnosine is an intracellular buffer. The intake of β-alanine, combined with carbohydrate and protein, enhanced loading in human muscle. aim the present study was to examine if muscle by β-alanine co-ingestion glucose male rats. Thirty-six rats were divided into three groups supplemented for four weeks: (βA group, 1.8% drinking water), (βAGL 5% control (C water). During supplementation period, exercised (20 m·min-1, 10 min·day-1, 4 days·week-1 weeks). concentration quantified soleus...
Background: Dysmenorrhea (painful menstruation) is a common health problem in women of reproductive age, affecting the individual’s health, job performance, and quality life. Objectives: This research investigated effect three ten-day yoga courses zinc sulfate on primary dysmenorrhea non-athlete girls. Methods: Forty-eight girls (18 to 25 years old) suffering from Karaj participated this clinical trial. Cluster sampling was used select subjects, they were allocated four groups: The placebo...
Leptin and adiponectin, adipose tissue secreted cytokines, play key role inobesity cardiovascular disease. Although the physiopathological mechanisms underlying these associations are largely unknown. Venous blood samples were obtained before after an acute bout of moderate cycling test in eighty nonâ€trained adult obese men (BMI: 33.54 ± 3.43 kg/m2) that participated this study by accidentally. Blood used for measuring serum leptin adiponectin. No significant differences found exercise...
PURPOSE: To investigate effects of 14 days spirulina supplementation on oxidative stress responses climbers at high altitude. Spirulina is a source antioxidants, which can protect against damage. METHODS: Eighteen apparently healthy men and women mountaineers (age 24.87±5yr, height 170.7±15.34cm, weight 75.92±17.21kg) volunteered to participate in one group pretest-posttest study design. All participants completed two winter ascents the summit (4,000meters) week before as well after...
Background Ingesting creatine and sodium bicarbonate alone or together improves anaerobic performance; however, the combined effects on taekwondo athletes remain unknown. METHODS In a double‐blind, randomized, placebo‐controlled study, 40 elite male (21.4±1y; 180.5±7.31cm; 72.7±8.59kg) were assigned to 5 groups: monohydrate+sodium (Cr+SB: 20gr Cr+0.5gr.kg −1 SB+0.5g.kg maltodextrin), monohydrate (Cr: Cr+0.5g.kg (SB: 0.5gr.kg placebo (PL: cellulose+0.5g.kg control (CO). Participants ingested...
Background: the supinated foot is one of lower limb abnormalities that associated with navicular drop and may be affected by leg muscles. The aim this study was to investigate effects 8-week corrective exercises improve static dynamic balance foot.Materials methods: current research a quasi-experimental study, in which twenty 18-25 male subjects all suffer were chosen purposefully into two groups (10) experimental control. Before training program legs test subjects, measured force platform....
Abstract Background : To examine the effects of varying doses caffeine on autonomic reactivation following anaerobic exercise. Methods Recreationally active males (N=20; 24±2y) participated in a randomized, double-blind, placebo-controlled, crossover study where participants ingested: (1) Control (CON; no supplement), (2) non-caffeinated placebo (PLA), (3) 3-mg∙kg -1 (CAF3) or (4) 6-mg∙kg (CAF6) prior to Wingate testing. Parasympathetic (lnRMSSD, primary outcome) and global HRV (lnSDNN,...
