The purpose of study was to resolve the effect of plyometric training and repeated sprint training on physical performance. The study was conducted on 41 subjects in two experimental groups (plyometric/repeated sprints training). Before and after the training program, subjects were subjected to diagnostic procedures that included standard test protocols. Results proved a statistically significant difference only after the plyometric training program compared to the repeated sprint group in countermovement jump (8.65% vs. 2.21%). In variable repeated jumps, an increased value was recorded (2.9% vs. 4.29%), like in sprint variables after the training program where certain trends of progress happened after the repeated sprint ability training and the specificity of the program (5 m = 0.89%, 10 m = 1.07% and 25 m = 1.35%), while plyometric training recorded unchanged values at 5 and 10 m, and a 0.27% improvement at 25 m. Stagnation of the 20-yard test was recorded in both groups. There was no difference between training programs in any variables of functional capacities, with similar measures recorded in repeated sprint ability. After six weeks of both training types, positive changes can be expected in explosive strength of lower extremities, increases in acceleration area, and maximum speed.

The aim of the study was to determine the effects of short-term (4 weeks, twice a week: 8 sessions) plyometric training on agility, jump, and repeated sprint performance in female soccer players. The study comprised 17 females performing this sports discipline. The players were randomly divided into two groups: with plyometric training (PLY) and the control (CON). All players followed the same training program, but the PLY group also performed plyometric exercises. Tests used to evaluate physical performance were carried out immediately before and after PLY. After implementing the short PLY training, significant improvement in jump performance (squat jump: p = 0.04, ES = 0.48, countermovement jump: p = 0.009, ES = 0.42) and agility (p = 0.003, ES = 0.7) was noted in the PLY group. In the CON group, no significant (p > 0.05) changes in physical performance were observed. In contrast, PLY did not improve repeated sprint performance (p > 0.05) among female soccer players. In our research, it was shown that PLY can also be effective when performed for only 4 weeks instead of the 6–12 weeks typically applied.

El objetivo de esta investigación es analizar el efecto de un programa de fuerza mediante tecnología isoinercial durante cuatro semanas, en la mejora del rendimiento en mujeres de deportes colectivos con carácter intermitente. La muestra estaba compuesta por seis mujeres con una edad media de 21±1.79 años. Se realizaron los test de cambios de dirección V-cut, fuerza explosiva counter movement jump y repeated sprint ability sobre 40 m. Los principales resultados muestran que se mejoraron todas las variables analizadas mediante el entrenamiento con tecnología isoinercial. Además, presentaron diferencias significativas (p<.05) en las variables de fuerza explosiva y de repeated sprint ability. Por lo tanto, un programa de entrenamiento de fuerza a través de tecnología isoinercial durante cuatro semanas de entrenamiento es suficiente para la mejora de los cambios de dirección, la resistencia a la repetición de esprines y la fuerza explosiva de piernas. The aim of this research is to analyse the effect of a four-week strength programme using isoinertial technology on performance improvement in women in team sports on an intermittent basis. The sample was composed of six women with an average age of 21 (±1.79 years). The tests of V-cut direction changes, explosive force counter movement jump and repeated sprint ability over 40 m were performed. The main results show that all the variables analysed are improved by training with isoinertial technology. They present significant differences (p<.05) in the variables of explosive strength and repeated sprint ability. Therefore, a strength training program using isoinertial technology during four weeks of training is sufficient for the improvement of direction changes, resistance to repeated sprinting and explosive leg strength.

The aim of this study was to describe the time course (within 2 h post-exercise) of heart rate variability (HRV) recovery following a traditional repeated sprint ability (RSA) test applied to youth soccer players. Twenty-four young soccer players (18.4 ± 0.5 years) undertook the following assessments: (1) 10 min rest in the seated position for HRV assessment; (2) a repeated sprint ability (RSA) test; (3) passive recovery in the seated position for 10 min, immediately after finishing the RSA test and 1 h and 2 h post-RSA test. During the HRV measurements (using the natural log of root mean square difference of successive normal RR intervals—lnRMSSD) the participants were instructed to assume a comfortable sitting position, remaining awake and breathing spontaneously for 10 min. Magnitude-based inference was used in the analyses. After the RSA test, the post-1 h measure was almost certainly lower than the resting measure, but almost certainly higher than the lnRMSSD measured post-RSA test. The lnRMSSD post-2 h was likely lower than the resting lnRMSSD and very likely higher than post-1 h. In conclusion, lnRMSSD is severely depressed after performing an RSA test, and reactivation is incomplete after 2 h of passive recovery. This result should be considered by practitioners when applying successive training sessions within intervals shorter than 2 h.

The main aim of the study was to investigate the differences in repeated sprint ability of first- compared to second-division referees at the beginning and in the middle of the soccer season. Twenty-seven main and 51 assistant referees, from the first (age 36.2 ± 5.3) and the second (age 28.8 ± 3.9) soccer divisions, performed two fitness tests—at the beginning and at mid-season, consisting of a repeated sprint test of 6 × 40 m and 5 × 30 m sprints for the referees and assistant referees, respectively. While no differences were found among the first division’s main referees, significant improvement ( p < .05) was found among the second division’s main referees at mid-season compared to the beginning of the season in ideal sprint time (31.97 ± 1.5 vs. 32.47 ± 1.3 s) and total sprint time (32.62 ± 1.4 vs. 33.10 ± 1.1 s), respectively. The main referees' ideal sprint time and total sprint time were significantly faster ( p < .05) in the second compared to the first division, at pre-season and at mid-season. Significant correlations were found between age and ideal sprint time ( r = .63) and age and total sprint time ( r = .66) among the main referees, but not between age and performance indices among the assistant referees. The findings demonstrated a superiority of the second over the first division's referees in anaerobic capabilities, suggesting that training program should be specific for each division. It may also indicate that variables other than physical capabilities determine referees' professional status and referee's advancement from second to the first division.
