The Effect of Two Generic Aerobic Interval Training Methods on Laboratory and Field Test Performance in Soccer Players

Abstract

The purpose of this study was to compare the effects of 2 generic aerobic training models, based on peak running velocity in Carminatti's test (PVT-CAR) in U-20 elite soccer players. Seventeen soccer players (age: 17.9 ± 1.0 years; 178.6 ± 5.0 cm; 73.6 ± 6.6 kg; 11.1 ± 1.3%) from a team competing in a national junior league took part in the study. The athletes performed a series of pre- and posttraining tests (incremental test on a treadmill to determine the maximal oxygen uptake [(Equation is included in full-text article.)], velocity at maximal oxygen uptake [(Equation is included in full-text article.)], the lactate threshold [LT], and T-CAR). The interval training models applied were with 180° direction change (T12:12; n = 9) and without direction change (T6:6; n = 8). No significant interaction (time vs. group) was observed for the majority of variables analyzed (p > 0.05), although significant main effects in time were evident regarding peak treadmill velocity (PVTREAD) (F = 56.3, p < 0.0001), (Equation is included in full-text article.)(F = 35.8, p < 0.0001), LT (F = 57.7, p < 0.0001), and PVT-CAR (F = 52.9, p < 0.0001). Moreover, there was no significant change in (Equation is included in full-text article.)between pre and posttraining period (F = 4.26, p = 0.056) in both training groups. Thus, it can be concluded that the prescribed training with and without direction change in the intensity of the PVT-CAR increases the PVTREAD, the (Equation is included in full-text article.), the LT, and the PVT-CAR similarly.

Physiological Responses During the Time Limit at 100% of the Peak Velocity in the Carminatti’s Test in Futsal Players

“…Previous studies have already shown that efforts lasting ≈ 2 to 4 min at an intensity near to maximal or maximal (e.g. 100%PVT-CAR) are capable to induce a high cardiovascular demand (Da Silva et al, 2015; Ferrari Bravo et al, 2008; Helgerud et al, 2001; Laursen et al, 2004), being an effective approach to improve the cardiorespiratory and metabolic function, and, in turn, to enhance the athletes physical performance (Ferrari Bravo et al, 2008; Helgerud et al, 2001; Impellizzeri et al, 2006). …”

“…Traditionally, the HR and peak velocity derived from intermittent field testing are the two most commonly measured physiological markers used for prescribing and controlling exercise intensity in the field conditions (Buchheit and Laursen, 2013). For instance, Fernandes da Silva et al (2015) showed that training with and without direction change at the intensity of the 100%PVT-CAR was effective in improving aerobic power and capacity, and the ability to perform high-intensity intermittent activities in U-20 elite soccer players. Furthermore, Ferrari Bravo et al (2008) and Helgerud et al (2001) demonstrated that 4 sets of 4 min at 90-95% of the HRmax with 3 min of active recovery at 60-70% of the HRmax were efficient training stimuli to increase the cardiorespiratory function and soccer performance (e.g.…”

“…Moreover, maximal aerobic power plays a key role in determining the magnitude of individual’s perceived exertion during futsal training sessions (Milanez et al, 2011). Thus, the use of the peak velocity (PV) from intermittent field tests with varied distances and direction change has been an interesting alternative to evaluate aerobic power in team sports (Dittrich et al, 2011) and it has been used for the prescription of interval training (Da Silva et al, 2015). Besides its applicability, practicality, low financial cost and high ecological validity (Svensson and Drust, 2005), PV is also associated with maximum aerobic speed (MAS) and repeated sprint ability (Da Silva et al, 2011).…”

“…However, this model was designed primarily based on laboratory tests (Hill et al, 2003), aiming at training of endurance athletes. In light of these applications, Fernandes da Silva et al (2015) reported the effectiveness of maximal aerobic power training prescription from the PV reached in the Carminatti’s Test (PVT-CAR) using set duration (4 x 4 min) according to the traditional model (Helgerud et al, 2001), without the sets being individualized by the athlete’s Tlim. Considering that precision in training prescription is one of the main aspects that can modify metabolic responses of trained athletes (Buchheit and Laursen, 2013), it is fundamental to identify physiological responses in the Tlim to individualize aerobic power training of futsal players.…”

Influence of Transcranial Direct Current Stimulation on Lower Limb Muscle Activation and Balance Ability in Soccer Player

“…7 As leg muscle is employed in jump, kick, tackle, turn, speeding, and turn, enhancement in its strength is relevant to improvement of such skills. 8 Foundation for explosive movement lies in leg muscular strength and leg muscular power has much impact on game performance. 9 Balance can be classified into static balance and dynamic balance.…”
