and in swimming flume conditions. It was hypothesized that using a wetsuit would enhance 400-m front crawl performance, reduce physiological responses, and increase swimming efficiency. Complementarily, lower physiological and higher technical variables values were expected with performance in the

As an alternative and an inexpensive method that simulates speed skating conditions

, enhancement of straight-line running fitness should potentially focus on CS and D ′ parameters derived from the linear AOT. Knowing the CS has important implications for training and testing given its utility as a fatigue threshold. Exercise above or below CS elicits different physiological responses in

a wide range of players’ density showing contrasting results as per physiological responses. 2 Recently, densities of 300 m 2 were proposed to develop anaerobic performance in soccer players using all-out SSG (ie, SSG 300 ; functional training). 4 The SSG 300 was shown to induce BLc in the range

-sprint training might not account for these individual differences and thus could be a contributing factor in the varying outcomes and levels of success ( 11 ). The issue of individual differences in the recovery between sprints is particularly pertinent in young athletes, where the physiological responses to

The quality of the swimming session was assessed by the physiological responses and biomechanical alterations during a 5 × 400-m endurance training set and a 10-second sprint of tethered swimming.
