Abstract The aim of this study was to assess physical fitness, match performance and development fatigue during competitive matches at two high standards professional soccer. Computerized time-motion analyses were performed 2-7 times the season on 18 top-class 24 moderate soccer players. In addition, players Yo-Yo intermittent recovery test. 28 58% more (P < 0.05) high-intensity running sprinting, respectively, than (2.43 ± 0.14 vs 1.90 0.12 km 0.65 0.06 0.41 0.03 km, respectively). better...

Sports Exerc., Vol. 35, No. 4, pp. 697–705, 2003. Purpose To examine the physiological response reproducibility of intermittent recovery test its application to elite soccer. Methods Heart rate was measured, metabolites were determined in blood muscle biopsies obtained before, during, after 17...
Purpose: To examine muscle and blood metabolites during soccer match play relate it to possible changes in sprint performance. Methods: Thirty-one Danish fourth division players took part three friendly games. Blood samples were collected frequently the game, biopsies taken before after game as well immediately an intense period each half. The performed five 30-m sprints interspersed by 25-s recovery periods half (N = 11) or exercise 20). Results: Muscle lactate was 15.9 ± 1.9 16.9 2.3...
Purpose: To examine the activity profile and physical loading of elite female soccer players during match play to study relationship between training status performance. Methods: Time-motion analysis HR recordings were performed on 14 competitive matches. In addition, carried out a laboratory treadmill test Yo-Yo intermittent recovery test. Results: The total distance covered game was 10.3 km (range: 9.7–11.3) with high-intensity running (HIR) accounting for 1.31 (0.71–1.70). HIR 125 times...
Abstract To examine the activity profile and physiological demands of top-class soccer refereeing, we performed computerized time-motion analyses measured heart rate blood lactate concentration 27 referees during 43 competitive matches in two top Danish leagues. relate match performance to physical capacity training, several tests were before after intermittent exercise training. Total distance covered was 10.07 - 0.13 km (mean s x ), which 1.67 0.08 high-intensity running. High-intensity...
In elite outfield players, the average work rate during a soccer match, as estimated from variables such heart rate, is approximately 70% of maximal oxygen uptake ( max). This corresponds to an energy production ~5700 kJ (1360 kcal) for person weighing 75 kg with max 60 ml kg-1 min-1. Aerobic appears account more than 90% total consumption. Nevertheless, anaerobic plays essential role matches. During intensive exercise periods game, creatine phosphate, and lesser extent stored adenosine...
Purpose: To examine the physiological response, reliability, and validity of Yo-Yo intermittent recovery level 2 test (Yo-Yo IR2). Methods: Thirteen normally trained male subjects carried out four IR2 tests, an incremental treadmill (ITT), various sprint tests. Muscle biopsies blood samples were obtained, heart rate was measured before, during, after test. Additionally, 119 Scandinavian elite soccer players on two to occasions. Results: performance 591 ± 43 (320-920) m or 4.3 (2.6-7.9) min....
The relationship between quadriceps muscle temperature ( T m ) and sprint performance was evaluated during soccer matches in 25 competitive players. In one game, determined frequently n =9). another eight players performed low‐intensity activities at half‐time (re‐warm‐up, (RW), whereas recovered passively (CON). 36.0±0.2 °C rest increased P <0.05) to 39.4±0.2 before the game remained unaltered first half. At half‐time, decreased 37.4±0.2 °C, but 39.2±°C second CON RW, core c were similar...
1. Eight subjects performed one‐legged, dynamic, knee‐extensor exercise, first at 10 W followed by min rest, then an intense, exhaustive exercise load (65 W) lasting 3.2 min. After 60 recovery, was for 8‐10 each 20, 30, 40 and 50 W. Measurements of pulmonary oxygen uptake, heart rate, blood pressure, leg flow, femoral arterial‐venous differences content lactate were as well determination ATP, creatine phosphate (CP) inosine monophosphate (IMP) concentrations on biopsy material from the...
We sought to study the physical demands and match performance of women soccer players. Nineteen top-class 15 high-level players were individually videotaped in competitive matches, time-motion analysis performed. The changed locomotor activity >1,300 times a game corresponding every ~4 seconds covered 9-11 km total. ran 28% longer (P < 0.05) at high intensities than (1.68 ± 0.09 1.33 0.10 km, respectively) sprinted 24% 0.05). group had decrease 25-57% intensity running final minutes compared...
Ageing is thought to be associated with decreased vascular function partly due oxidative stress. Resveratrol a polyphenol, which in animal studies has been shown decrease atherosclerosis, and improve cardiovascular health physical capacity, part through its effects on Sirtuin 1 signalling an improved antioxidant capacity. We tested the hypothesis that resveratrol supplementation enhances training-induced improvements parameters aged men. Twenty-seven healthy physically inactive men (age: 65...
From 19th to 22nd November 2018, 26 researchers representing nine countries and a variety of academic disciplines met in Snekkersten, Denmark, reach evidence-based consensus about physical activity older adults. It was recognised that the term ‘older adults’ represents highly heterogeneous population. encompasses those remain active healthy throughout life-course with high intrinsic capacity very old frail low capacity. The is drawn from wide range research methodologies within epidemiology,...
This study investigated isokinetic peak‐ and angle‐specific hamstring/quadriceps strength ratios (conventional H/Q ratio) obtained during concentric eccentric muscle contraction examined the influence of joint angular velocity effect gravity correction on these ratios. Also, a ‘functional’ ratio was defined by calculating hamstring relative to quadriceps (H eee /Q eon representative for knee extension) flexion). The calculated based peak moment 50 o ‐moment (0 = full at velocities 30, 120...
The effect of intense training on endothelial proliferation, capillary growth and distribution vascular factor (VEGF) basic fibroblast (bFGF) was examined in human skeletal muscle. Two intermittent knee extensor protocols (at approximately 150% (Study 1) versus 90% 2) leg (O(2) max)) were conducted. Muscle biopsies obtained throughout the periods for immunohistochemical assessment capillarization, cell proliferation (Ki-67-positive cells), VEGF bFGF. In Study 1, microdialysis samples...
