2018/4/24
Purpose The aim was to determine the feasibility of a 6-wk speed-based exercise program that could be used to initiate new exercise behaviors and to improve rapid movement in older adults approaching ...
Effects of Pedal Speed and Crank Length on Pedaling Mechanics during Submaximal Cycling
BIOMECHANICS COORDINATION ENDURANCE CYCLING CRANK LENGTH
<
2017/4/13
During submaximal cycling, the neuromuscular system has the freedom to select different intermuscular coordination strategies. From both a basic science and an applied perspective, it is important to ...
Oral L-citrulline supplementation enhances cycling time trial performance in healthy trained men: Double-blind randomized placebo-controlled 2-way crossover study
Ergogenic Human L-Citrulline Nitric oxide (NO) Sport performance
<
2016/3/1
Background: Many human studies report that nitric oxide (NO) improves sport performance. This is because NO is
a potential modulator of blood flow, muscle energy metabolism, and mitochondrial respira...

<
2016/2/23
The purpose of the study was to measure the demands of off-road cycling via portable spirometry, leg-power output (PO), heart rate (HR) and blood lactate (BLa) concentration. Twenty-four male competit...
The effect of turmeric (Curcumin) supplementation on cytokine and inflammatory marker responses following 2 hours of endurance cycling
Immunity Interleukins Natural polyphenols
<
2015/7/30
Endurance exercise induces IL-6 production from myocytes that is thought to impair intracellular defence mechanisms. Curcumin inhibits NF-κB and activator protein 1, responsible for cytokine transcrip...

2015/7/29
In a double-blind placebo-controlled crossover study, 13 male cyclists (26 ± 10 y, 71 ± 9 kg, 176 ± 6 cm) were randomized into 2 groups and received caffeine (CAF) ...
Post-prandial carbohydrate ingestion during 1-h of moderate-intensity, intermittent cycling does not improve mood, perceived exertion, or subsequent power output in recreationally-active exercisers
Recreational exercise Non-caloric Sport beverage
<
2015/7/27
This study compared the effects of ingesting water (W), a flavored carbohydrate-electrolyte (CE) or a
flavored non-caloric electrolyte (NCE) beverage on mood, ratings of perceived exertion (RPE), and...

<
2015/7/14
Under these experimental conditions, liquid C+P ingestion immediately after
exercise increases fat oxidation, increases recovery, and improves subsequent same day, 60 min
efforts relative to isoener...
