Thirty elite Swedish football players were divided into two groups. One group underwent specific hamstring training consisting of eccentric overload of the hamstring 1-2 times per week whereas the other did not. |
|
The physical demands during a soccer match, as estimated by heart-rate and body-temperature measurements, correspond to ~70% of maximum oxygen uptake. |
|
A group of sixteen elite soccer players carried out during the season an additional aerobic high-intensity training once a week for 12 weeks. E |
|
During a 4-wk period endurance-trained subjects replaced their ordinary aerobic training with 3-4 weekly sessions of intermittent high-intensity exercise (8-12 sprint runs of 30 s, separated by 3 min of rest). |
|
For a 8-wk training period a group of habitually active subjects performed 3-5 times a week either sprint training (ST; 6-s sprints, 1 min rest; n=6) or speed endurance training (SET; 8 30-s runs at 130% VO2-max separated by 1.5 min of rest; n=7). |
|
After the pre-season, forty-two elite, junior soccer players underwent in a 7-wk period twice a week either an intense aerobic interval (ITG; 4 x 4 min running at 90-95% HRmax, 3 min rest; n=21) or a repeated sprint training (STG; 3 x 6 maximal shuttle sprints of 40 m, n=21) session. |
|
When carrying out fitness training with the ball one should make sure that players are actually exercising at the desired intensity. |
|
A study compared the physiological and performance effects of generic versus specific aerobic training in soccer. |
|
This study analyzed 186 players for a total of 416 individual games in the Italian serie A. |
|
Data collected during a season from 20 professional soccer players of a successful team taking part in a major European National League, and reaching the UEFA Champions League semi-final, showed that: 1) Physical performance during a match is related to the activity completed by the opponent team. The players run further total distance and carry out more high-intensity running when playing against higher quality opponents; 2) First half activity influences physical performance in the second half. |
|
Computerized time motion analysis have revealed that during a game top class soccer players perform ~ 2.5 km at high-intensity running and ~ 0.6 km at sprinting which are 28 and 58% respectively, more than what were performed by moderate level professional players. |
|
Due to its specificity and practicality, the Yo-Yo intermittent recovery (IR) tests (level 1 and 2) are extensively used in soccer to assess players’ abilities to perform repeated high-intensity exercise. |
|
Soccer players have been reported to perform less high-intensity running at the beginning of the second half compared with the first half of a match. Such an effect is likely due to a decline in muscle temperatures during half time. |
|
Fatigue, or rather not optimal physical performance, may develop during high-level soccer games I) after short-term intense periods in both halves, II) in the initial phase of the second half, and III) towards the end of the game. |
|
Eccentric hamstring peak torque measured in 10 professional soccer players was observed to decrease after the half-time interval and progressively during a match. |
|
Neuromuscular and biochemical parameters were evaluated at rest, at the end as well as in the days after a game in 17 elite female soccer players. |
|
Sixteen elite junior players completed the Loughborough Soccer Passing Test (LSPT) both before and after the first and second half of an unofficial game as well as after 5 min of simulation of high-intensity activity (HIS). |
