Most physiological profiles of élite soccer players originate from Western Europe and North America. Unfortunately, there is a scarcity of descriptive data on the physical characteristics of Asian soccer players. Therefore, the purpose of this study was to evaluate the physiological profiles of élite soccer players in Hong Kong. It was conducted in conjunction with the selection of the Hong Kong team before the 1990 Beijing Asian Games. In all, 24 professional soccer players were selected from a pool of 180 players as subjects for the study. The following means(s.d.) were observed: height 173.4(4.6) cm; weight 67.7(5.0) kg; body fat 7.3(3.0)%; forced vital capacity (FVC) 5.1(0.6) l; maximum oxygen uptake (VO2max) 59.1(4.9) ml kg-1 min-1; anaerobic threshold (AT 80.0(7.2)% of VO2max; alactic power index 13.5(2.4) W kg-1; lactic work index 298(27) J kg-1; peak isokinetic dominant knee extensor and flexor strengths 2.72(0.36) Nm kg-1 and 1.65(0.20) Nm kg-1. On average the physique of Hong Kong soccer players appeared to be smaller and lighter than those found in Europe, which may be one of the key factors that contribute to the lack of success of Hong Kong soccer teams in international competition.

Strength ratio between agonist and antagonist muscles provides significant information about muscular equilibrium, which helps to detect musculoskeletal changes and to guide preventive and rehabilitation programs. Isokinetic dynamometry provides reliable values for muscle torque and subsequently on the force ratio between knee flexors and extensors. However, this method is not clinically accessible. A possible alternative to evaluate this force is the One-Repetition Maximum test (One-Rep Max or just 1-RM), which is the most commonly used test for dynamic force assessment. However, there is no report in the literature of the use of 1-RM test for the quantification of knee flexors and extensors ratio. For this reason, the objective of this study was to use the 1-RM test to measure the ratio between knee extensors and flexors in young adults in order to find reference values. The studied sample was composed of 80 young adults (40 men and 40 women), mean age of 22.21 (±3.58) years with no musculoskeletal injuries. They were submitted to the following procedure: IPAQ-short version, weighing and prognostic of 1-RM, warm-up, and unilateral 1-RM test (at the flexor and extensor machine). After the test application, the data were analyzed and the mean values for the ratio between agonist/antagonist found were 52.34% (±9.72) for men and 43.19% (±5.82) for women (which were significantly different between groups). The values found in the present study may be used as reference for asymptomatic individuals with similar age.

“…Specific to the hip joint, a number of studies have assessed the reliability of voluntary torque generation with subjects in different positions (Calmels et al, 1997;Donatelli et al, 1991;Emery et al, 1999;Kea et al, 2001;Poulmedis, 1985), and from a variety of populations (Arokoshi et al, 2002;Eng et al, 2002;Hsu et al, 2002). Cahalan et al (1988) reported high test-retest reliability (intraclass correlation (ICC) coefficient = 0.96) of standing isokinetic concentric and eccentric hip abduction, adduction, flexion, and extension strength.…”
