Short Post-warm-up Transition Times Are Required for Optimized Explosive Performance in Team Sports

Although a 3- to 7-min re-warm up (RW) elicits performance and physiological benefits after half-time (HT), a time-efficient and feasible RW protocol is required for the use of an RW in the athletic setting. This study aimed to investigate the effect of a 1-min RW at high-intensity on the performance and physiological responses during the Loughborough Intermittent Shuttle Test (LIST). In a randomized and counterbalanced cross-over design, 12 male amateur intermittent team sports players (soccer, basketball, handball, and lacrosse; age, 22 ± 2 years; height, 1.70 ± 0.08 m; body mass, 65.1 ± 8.3 kg; body mass index, 22.4 ± 1.9 kg m−2; VO2max, 53.5 ± 4.5 ml kg−1 min−1) performed the LIST. The LIST comprised two 45-min halves separated by a 15-min HT. Each half comprised repetitions of exercise cycles consisting of 3 × 20-m walking, 1 × 20-m maximal sprint, 3 × 20-m jogging, and 3 × 20-m running. During the HT, the participants were assigned to a control trial (CON; 15-min seated rest) or an RW trial (1-min running at 90% of the maximal oxygen uptake after a 14-min seated rest). Compared to the CON, the RW prevents reductions in sprint performance at the fourth and sixth periods of the LIST (fourth: 2.4%, p = 0.002, d = 1.68, sixth: 3.6%, p = 0.012, d = 1.74) and a decrement of gastrointestinal temperature during HT (0.5°C, p = 0.010, d = 1.41). Moreover, the RW decreased the electromyogram amplitude of maximal voluntary contraction (MVC) after HT (12%, p = 0.017, d = 1.12) without a decrease of maximal voluntary contraction force, suggesting an increased neuromuscular efficiency (9%, p = 0.048, d = 0.58). The RW also increased the mean heart rate in the initial part of the second half (4 bpm, p = 0.016, d = 0.38). In conclusion, the RW improved sprint performance, core temperature, muscle activation, and heart rate in the second half of the LIST. The findings suggest that the RW should be recommended for intermittent team sports players when longer RWs are not possible.

Rhythmic Gymnasts

Τhis study examined changes in hip joint flexion angle after an intermittent or a continuous static stretching protocol of equal total duration. Twenty-seven female subjects aged 19.9 ± 3.0 years (14 artistic and rhythmic gymnasts and 13 team sports athletes), performed 3 min of intermittent (6 × 30 s with 30 s rest) or continuous static stretching (3 min) of the hip extensors, with an intensity of 80–90 on a 100-point visual analogue scale. The order of stretching was randomized and counterbalanced, and each subject performed both conditions. Hip flexion angle was measured with the straight leg raise test for both legs after warm-up and immediately after stretching. Both stretching types equally increased hip flexion angle by ~6% (continuous: 140.9° ± 20.4° to 148.6° ± 18.8°, p = 0.047; intermittent: 141.8° ± 20.3° to 150.0° ± 18.8°, p = 0.029) in artistic and rhythmic gymnasts. In contrast, in team sports athletes, only intermittent stretching increased hip flexion angle by 13% (from 91.0° ± 7.2° to 102.4° ± 14.5°, p = 0.001), while continuous stretching did not affect hip angle (from 92.4° ± 6.9° vs. 93.1° ± 9.2°, p = 0.99). The different effect of intermittent vs. continuous stretching on hip flexion between gymnasts and team sports athletes suggests that responses to static stretching are dependent on stretching mode and participants training experience.

Final Round

Porprov VI East Java Province will be held in four districts namely Gresik, Bojonegoro, Tuban and Lamongan. Banyuwangi Regency participates in this multi-event sports event held every 2 years with great enthusiasm. Where preparation as well as pre Porprov has been followed. One of the sports that is attracting enough attention is the women's Basketball sports. Where in the pre-warm-up event Porprov was able to wipe out all matches with a win. Plus in this generation there are 2 heroines from Gandrung who represent East Java to take part in Pre-PON, adding to the solid Banyuwangi women's basketball team. Naturally, the management of the coach is targeting this team to enter the final round in this VI VI porprov. In this Porprov we provide assistance to the women's basketball coach team to help maintain the physical and psychological condition of the athletes in attending this event. With a fairly tight schedule to compete 1 time a day makes the athlete's physical and psychological decline. So we provide the right method to recover physically and psychologically from athletes who face a hectic schedule. The method for carrying out this activity is (a) the preparation phase (b) the implementation phase of the mentoring at each match (c) the evaluation phase, which is to make a final report. The results of this mentoring activity were very positive, this can be seen (1) the Banyuwangi basketball women's team entered the final round and won the silver medal (2) the physical and psychological condition of the athlete was always maintained every day proved that there were no athletes who were injured and under perform, (3) the assistance process went smoothly without any significant obstacles.

Mean Reaction Time

Context: Referees’ physical and cognitive performance are important for successful officiating in team sports. There is a lack of research on cognitive performance of referees in general, and none in futsal. Purpose: To assess referees’ performance on the psychomotor vigilance task (PVT) before and after competitive futsal matches during the Football Association (FA) National Futsal League 2015/16. Methods: Fourteen futsal referees (mean [SD] age 34.3 [10.0] y) from the FA National Futsal group were included. The referees were required to undertake a 10-min PVT 60 min before the match kickoff time (pretest) and immediately after matches (posttest). They also completed the Brunel Mood Scale (BRUMS) questionnaire before the prematch PVT and after the postmatch PVT. Result: Data were analyzed by paired t tests comparing prematch and postmatch results. There was a significant difference in BRUMS parameters vigor (9.5 [2.5] prematch vs 6.3 [2.4] postmatch, P = .001) and fatigue (1.4 [1.3] prematch vs 5.6 [3.1] postmatch, P < .001). However, PVT performance was significantly improved (mean reaction time 248.3 [26.2] ms prematch vs 239.7 [22.4] ms postmatch, P = .023). Conclusions: The present results show, contrary to the authors’ initial hypothesis, that psychomotor performance is improved as opposed to decreased after a single match. The postmatch improvement suggests that exercise can acutely enhance cognitive performance, which could be used to inform warm-up practices (eg, optimal duration and intensity) geared toward optimizing referees’ cognitive performance during matches.

Small Improvement

High-intensity, short-duration warm-up techniques improve acute physical performance, but sparse research has examined their consequence when followed by intermittent activity, which is pertinent to team sports. The authors compared a 5-repetition-maximum (5RM) leg-press, a small-sided game (SSG), and a current team-sport warm-up in 10 semiprofessional soccer players after 2 intermittent-activity protocols consisting of 15 repetitions of a 60-s circuit that included sprinting, slalom, walking, jogging, decelerations, changes of direction, backward running, and striding activities. There was a large improvement in countermovement-jump height in the 5RM after the 1st intermittent-activity protocol (mean, ±90% CL 6.0, ±4.0%, P = .03) and a small improvement after the 2nd (4.6, ±4.0%, P = .04) compared with team sport. Reactive agility was moderately faster via 5RM after the 1st intermittent-activity protocol (3.1, ±2.6%: P = .04) and the 2nd (5.7, ±2.7%, P = .001) than via SSG. There was a small improvement in reactive agility after the 1st intermittent-activity protocol in the 5RM, compared with team sport (3.3, ±2.9%, P = .04). There was a small improvement in mean 20-m-sprint times after both intermittent-activity protocols in the 5RM, compared with SSG (4.2, ±2.0%, P = .01, and 4.3, ±2.0%, P = .01) and, after the 1st intermittent-activity protocol only, compared with team sport (4.2, ±2.1%, P = 0.02). Small increases in blood lactate concentration were observed (46.7, ±18.6%, P = .01) in the 5RM compared with the SSG after the 2nd intermittent-activity protocol. Improved performances after the 5RM warm-up should encourage practitioners to reduce activity time and include high-intensity tasks in team-sport warmups aimed at inducing a potentiating effect.
