Two mature elite Sambo wrestlers were studied during a 22-day pre-European Championship period, during which they were to lose weight and maintain their top physical performance characteristics. During this time the athletes underwent intensive training coupled with a hypocaloric diet. Both lost approximately 8% of their initial body weight, while maintaining their pre-weight loss maximum oxyge...

PURPOSE CrossFit(®) is a new but extremely popular method of exercise training and competition that involves constantly varied functional movements performed at high intensity. Despite the popularity of this training method, the physiological determinants of CrossFit performance have not yet been reported. The purpose of this study was to determine whether physiological and/or muscle strength m...

purpose the purpose of this investigation was to assess the effects of listening to music during warm-up on short-term supramaximal performances during the 30-s wingate test in highly trained athletes. methods twelve young male athletes (20.6±1.8 yrs, 177±4.4 cm and 72.3±5.3 kg) underwent two wingate tests in separate sessions with a recovery period of 48 h in-between, either after a 10 min of ...

Five male subjects performed three successive incremental work tests on an electronically braked cycle ergometer. The first and second tests were separated by thirty minutes of rest, the second and third by three minutes of maximum work. During the third test, venous blood lactate concentrations were still decreasing at work rates where they were increasing during the first two tests. The work ...

PURPOSE The aim of this study was to quantify the intensity of competition during two professional bicycle stage races: the Tour de France (Tour) and Vuelta a España (Vuelta). METHODS The HR responses of 18 world class cyclists were recorded during the races and compared with HR ranges that corresponded to four intensities of exercise that were measured in the laboratory with an incremental t...

BACKGROUND Many methods are used for determining the Anaerobic Threshold (AT) by means of sophisticated ergospirometer. OBJECTIVE To test the AT variation, detected by mathematical models and visual inspection, when low cost ergospirometer is used and intended for clinical application. METHODS Seventy nine apparently healthy subjects were volunteers in this study; from these, 57 men. The VO...

This study was designed to assess the validity of Conconi’s method, by means of heart rate and lactate threshold measurements to predict anaerobic threshold. The results presented in this paper, clearly demonstrate significant difference between anaerobic threshold values obtained by means of Conconi’s test (Conconi’s threshold) and anaerobic threshold values obtained by direct lactate blood co...

[Purpose] The purpose of this study was to clarify the validity of salivary α-amylase as a method of quickly estimating anaerobic threshold and to establish the relationship between salivary α-amylase and double-product breakpoint in order to create a way to adjust exercise intensity to a safe and effective range. [Subjects and Methods] Eleven healthy young adults performed an incremental exerc...

The objective of the study was to verify whether young males' balance was affected by 30min prolonged treadmill running (TR) at individual ventilatory (IVT) and anaerobic (IAT) thresholds in recovery time. The VO2max, IAT and IVT during an incremental TR were determined. Mean displacement amplitude (Acp) and velocity (Vcp) of center of pressure were recorded before (pre) and after (0min post; 5...
