ZHANG Rui is back
I think TANG Peng will come tomorrow.
YIP Pui Yin beated ZHU Lin
I think the super-endurnace resistant training and high-lactic running intervals are both taking effect on her body.

Introduction: In the past years, there is a rapid growth of soccer standard in Asia countries (FIFA, 2006). However, to our knowledge, the information about the fitness among Chinese elite youth soccer players is not available in the literature. Therefore, the purpose of this study was to investigate the maximal oxygen uptake (VO2max), sprint, jump, and ball shooting speed among Chinese elite youth soccer players.
Method: 47 Hong Kong elite youth soccer players (age: 13.6±0.6; weight: 52.3±9.4kg; height: 1.65±0.1m) participated in the study. Players have 2 training sessions per week each last for 90mins. Informed consent was obtained from players and their parents prior to the study. All players were free from injury at the time of data collection. VO2max test was conducted in the laboratory where the environment was well controlled (temperature: 23.7±0.8 °C; humidity: 59.2±5.5%; ambient pressure: 1010±2mmHg). The VO2max protocol has been used by elite youth soccer players and running economy was determined during the last 30s of the 4min run at 7km/h (Chamari et al, 2005). VO2 and heart rate (HR) were recorded during the whole running test. The other 3 tests were conducted outdoor where players performed: a) 30m sprints with a standing-start position, 3min rest between each of the 3 trials; countermovement jump on a portable force mat, 2min rest between each of the 3 jumps; c) 3-step shoot 4m from the goal (1m x 1m), 2min rest between each of the 8 trials. Best results of these tests were used for analysis.
Results and discussion: VO2max (relative: 58.6±5.3ml/min/kg; absolute: 3.01±0.5L/min); HRmax (199.4±7.8bpm); running economy (relative VO2: 42.5±4.4ml/min/kg; absolute VO2: 2.2±0.4L/min; HR: 161±12bpm); sprint time (5m: 1.22±0.1s; 10m: 2.04±0.1s; 15m: 2.75±0.2s; 20m: 3.45±0.2s; 30m: 4.81±0.3s); countermovement jump height (54.9±6.1cm); and ball shooting speed (77.1±9.5km/h). Compared with African players at the same age (Charami et al, 2005), Chinese elite youth soccer players have lower VO2max (65.3 vs 42.5ml/min/kg; 3.49 vs 3.01L/min) and running economy (38.8 vs 42.5ml/min/kg). To our knowledge, no comparable literature is available for sprint, jump, and ball shooting performances at the same age.

Introduction: The golden standard to assess aerobic ability is to measure the oxygen consumption (VO2) by using metabolic measurement device when subject running on a motorized treadmill until exhaustion (Stolen et al., 2005). However, the metabolic measurement device is expensive and may not be available to every soccer team/club. In addition, organizing one soccer team to continuously assess players’ VO2max require a huge amount of time and manpower. Therefore, heart rate (HR) has been used to estimate/predict the exercise intensity among soccer players (Esposito et al., 2004; Kemi et al., 2003). Once the relationship between HR and VO2 is established, coaches can use HR to estimate players’ VO2 in on-field situation. The purpose of this study is to examine the prediction of VO2 using HR among Chinese elite youth soccer players.
Method: 47 Hong Kong elite youth soccer players (age: 13.6±0.6; weight: 52.3±9.4kg; height: 1.65±0.1m) participated in the study. Players have 2 training sessions per week each last for 90mins. All players were free from injury at the time of data collection. VO2max test was conducted in the laboratory where the environment was well controlled (temperature: 23.7±0.8 °C; humidity: 59.2±5.5%; ambient pressure: 1010±2mmHg). The VO2max protocol has been used by elite youth soccer players (Chamari et al, 2005). VO2 and HR were recorded throughout the experiment at 5s interval.
Results and discussion: Correlation between HR and VO2 was 0.76 (p<0.001)>.
Sarah is back!!
She is the first athlete i picked up when i joined HKSI last year. The most tough girl i have ever met in elite sport area.
Come on! Get some muscle and power. And then some more medals...

WONG Steven - BMX
Recetnly, I train him for more than one month during which he gained 3kg muscle. At this same time, his anaerobic sprinting ability became stronger also. But this is not easy, he trained 6 days a week each with almost 2 hrs. He told me that why I never give him an "easy training", then i said "if i give u an easy training, then i am wasting your time". Your hard time in our training center will eventually show on your bike performance.
Below are his race results as from his personal website:
2005:
All China Games Gold Medalist
Flanders Cup Series #1 Elite Men (I won 3 out of 4 rounds)
Flemish Champion Junior Men
Regional Champion Junior Men
TC Keerbergen #1 Elite Men
AK Berlicum #1 Elite Men
2004:
In National Races I promoted to the Elite Category at the age of 16.
Belgian #3 in Elite Men
Belgian #2 in Elite Cruiser
World #7 in Cruiser 16
