Comparative Effects of Two Interval Shuttle-Run Training Modes on Physiological and Performance Adaptations in Female Professional Futsal Players

Abstract

The purpose of the present study was to analyze the effects of two shuttle-run interval training (SRIT) models with one and three directional changes per running bout on the aerobic and anaerobic performances of elite female futsal players. Sixteen players competing in the Brazilian National Division League took part in the study. The training protocols consisted of shuttle-run intervals organized in four sets of 4-min bouts with 3- min of rest intervals between the sets. The SRIT models were composed of one (7.5 s running and 7.5 s pause [SRIT7.5x7.5]; n=7) or three (15 s running and 15 s pause [SRIT15x15]; n=9) directional changes. The athletes performed the following tests before and after a 5-week training period: incremental treadmill test (ITT), Futsal Intermittent Endurance Test (FIET) [with respective peak speeds (PS)] and a repeated sprint ability (RSA) test. After the training period, PSFIET and speed at the second lactate turnpoint were very likely and almost certainly increased in both training regimens, respectively. SRIT15x15 induced possibly greater improvements in PSITT (+3.28%, 90%CL -0.16 to 6.82) and RSAmean (+1.17%, 90% CL -0.68 to 3.05) than SRIT7.5x7.5. In addition, SRIT15x15 resulted in a likely greater improvement in running economy (+4.33%, 90% CL -0.35 to 9.23) compared with SRIT7.5x7.5. In elite female futsal players, SRIT15x15 is a promising strategy to enhance performance-related physical fitness attributes in a shortterm period (5 weeks) during the preseason, due to its superior effects on these important aerobic and anaerobic qualities than a protocol with fewer directional changes.

The effects of short term detraining and retraining on physical fitness in elite soccer players

“…On the contrary, improvements in repeated sprint performance through aerobic high-intensity training might be associated with the training period during the preseason. Recently, Teixeira et al [ 29 ] reported that high-intensity aerobic training involving shuttle-run intervals (4 × 4 min) for five weeks during the preseason enhanced repeated sprint ability with increased aerobic performance in elite athletes. When considered, these findings suggest that more than three weeks of high-intensity aerobic training is required to develop repeated sprint performance during preseason in elite players.…”

Importance of Agility Performance in Professional Futsal Players; Reliability and Applicability of Newly Developed Testing Protocols

“…Furthermore, all three field playing positions (e.g., guards, wingers, pivots) must be able to effectively change their positions during the game, which actually accentuate the necessity for their agility performance. In other words, irrespective of their primary game specific tasks (i.e., defender—keeping the ball, making the smart passes; winger—sprinting and passing; pivot [topman]—attacking and scoring), all futsal players must possess exceptional agility with and without the ball [25,26].…”

“…Compared to soccer, futsal players perform more changes of direction during a game, while dribbling a smaller ball across a reduced court size [26]. For these reasons, both CODS and RAG may be especially important physical fitness parameters in futsal [25,26], and hence specific research within the sport is needed. However, no study so far has examined tests of agility-components that involved dribbling with the ball in this sport.…”

“…However, no study so far has examined tests of agility-components that involved dribbling with the ball in this sport. This is particularly important as ball control while executing quick changes of direction in a reduced court size compared to other sports is a common characteristic of futsal [25,26]. The development of reliable and valid agility-based tests involving dribbling in futsal may assist professionals involved in this sport to choose appropriate testing protocols to evaluate players.…”

Predicting Maximal Lactate Steady State from Carminatti’s Shuttle Run Test in Soccer Players

“…Interestingly, for MLSS and all derived parameters during the T-Car test, HR values were above 85 % of HRmax (▶ Table 1). Likewise, a previous study showed that interval sessions in shuttle run mode, at submaximal intensities (86 and 89 % of sPeak), were an effective strategy for improving maximum and submaximal indices in elite futsal athletes [35]. However, that study [35] used another intermittent incremental test (i. e. FIET) and not T-Car; therefore, investigations are necessary regarding the use of submaximal variables derived from T-Car for training prescription.…”
