HYDRATION AND TEMPERATURE IN TENNIS – A PRACTICAL REVIEW
Dehydration heat stress body temperature electrolytes
2015/3/18
Competitive tennis is typically played in warm and hot environments. Because hypohydration will impair
tennis performance and increases the risk of heat injury, consumption of appropriate fluid leve...
CREATINE SUPPLEMENTATION AND SWIM PERFORMANCE: A BRIEF REVIEW
Phosphocreatine breaststroke butterfly ergometer
2015/3/18
Nutritional supplements are popular among athletes participating in a wide variety of sports. Creatine is
one of the most commonly used dietary supplements, as it has been shown to be beneficial in ...
FLEXIBILITY IS NOT RELATED TO STRETCH-INDUCED DEFICITS IN FORCE OR POWER
Flexibility force jumps static stretching
2015/3/18
Previous studies have demonstrated that an acute bout of static stretching may cause significant
performance impairments. However, there are no studies investigating the effect of prolonged stretch ...
CONTRIBUTION OF HAMSTRING FATIGUE TO QUADRICEPS INHIBITION FOLLOWING LUMBAR EXTENSION EXERCISE
Superimposed burst technique electromyography spectral median frequency
2015/3/18
The purpose of this study was to determine the contribution of hamstrings and quadriceps fatigue to
quadriceps inhibition following lumbar extension exercise. Regression models were calculated consi...
A COMPARISON OF THE EFFECTS OF FATIGUE ON SUBJECTIVE AND OBJECTIVE ASSESSMENT OF SITUATION AWARENESS IN CYCLING
Endurance cognition psychophysiology
2015/3/18
Maximal effort on a 30 km Time Trial (TT30) was examined to assess whether it would elicit changes in
objective and subjective tests of the participants’ perception of the environment and their abil...
EFFECTS OF CREATINE, GINSENG, AND ASTRAGALUS SUPPLEMENTATION ON STRENGTH, BODY COMPOSITION, MOOD, AND BLOOD LIPIDS DURING STRENGTH-TRAINING IN OLDER ADULTS
Exercise aging creatine loading strength training
2015/3/18
The effects of supplemental dietary creatine and a botanical extract consisting of ginseng and astragalus
were evaluated in 44 adults aged 55-84 years participating in a 12-week strength-training pr...
COMPRESSION GARMENTS AND RECOVERY FROM ECCENTRIC EXERCISE: A 31P-MRS STUDY
Magnetic resonance spectroscopy muscle damage
2015/3/18
The low oxidative demand and muscular adaptations accompanying eccentric exercise hold benefits for
both healthy and clinical populations. Compression garments have been suggested to reduce muscle
...
RECOVERY OF POWER OUTPUT AND HEART RATE KINETICS DURING REPEATED BOUTS OF ROWING EXERCISE WITH DIFFERENT REST INTERVALS
Interval training maintenance of power output
2015/3/18
This study examined the effect of recovery time on the maintenance of power output and the heart rate
response during repeated maximal rowing exercise. Nine male, junior rowers (age: 16 ± 1 years; b...
A COMPARISON OF UPPER-EXTREMITY REACTION FORCES BETWEEN THE YURCHENKO VAULT AND FLOOR EXERCISE
Gymnastics injuries biomechanics vaulting kinetics
2015/3/17
The purpose of this study was to examine reaction forces transmitted to the upper extremities of highlevel gymnasts during the round-off phase of the Yurchenko vault. A secondary purpose of this study...
RELIABILITY AND VALIDITY TESTING OF AN ARCHERY CHRONOMETER
Archery, electromyography (EMG)
2015/3/17
Keeping the arrow velocity constant during consecutive shots and responding to “clicker’s fall” are
considered to be an important feature of archery performance. A specially designed device called a...
A PILOT STUDY COMPARING TWO FIELD TESTS WITH THE TREADMILL RUN TEST IN SOCCER PLAYERS
Yo-Yo test, beep test, maximal oxygen uptake
2015/3/17
This study compares the performances obtained during soccer-specific field tests of the 20 m multistage
shuttle run test (MST) and the Yo-Yo intermittent endurance test (YIET), with the measured max...
STARTING BLOCK PERFORMANCE IN SPRINTERS: A STATISTICAL METHOD FOR IDENTIFYING DISCRIMINATIVE PARAMETERS OF THE PERFORMANCE AND AN ANALYSIS OF THE EFFECT OF PROVIDING FEEDBACK OVER A 6-WEEK PERIOD
Feedback, kinetic, kinematic, performance, sprint.
2015/3/17
The purpose of this study was twofold: (a) to examine if kinetic and kinematic parameters of the
sprint start could differentiate elite from sub-elite sprinters and, (b) to investigate whether
pro...
KINETIC CONSEQUENCES OF CONSTRAINING RUNNING BEHAVIOR
Ground reaction force, impact attenuation, shock
2015/3/17
It is known that impact forces increase with running velocity as well as when stride length increases.
Since stride length naturally changes with changes in submaximal running velocity, it was not c...
中国和德国具有不同的文化背景，幼儿所处的家庭、社会环境以及幼儿园的教育理念方法有很大的差别，通过用国际M-ABC测评工具测量比较两国幼儿的运动协调能力，不仅能掌握M-ABC在东西方不同文化环境下的适用性，而且有助于了解两国幼儿协调能力从4岁到6岁的发展变化特征和影响因素，为促进两国儿童的运动能力发展和健康成长具有重要的意义。
