The present study aimed at (i) investigating weekly variations in wellness ratings relative to Hooper indicators (HI): fatigue (wFatigue), stress levels (wStress), delayed onset muscle soreness (wDOMS), sleep quality/disorders (wSleep), and wHI across the full preparation season (PS) and (ii) comparing the aforementioned variables between three periods: early-PS, week (W) W1 to W11; mid-PS, W12 to W22; end-PS, W23 to W32. Ten elite young wrestlers were involved in this study (age, 16 ± 0.7 years; height, 163 ± 4.8 cm; body mass, 57.7 ± 9.0 kg; VO2max, 48.7 ± 1.4 mL/kg−1/min−1). Wellness status was monitored daily using the HI questionnaire. The main results were found in W26 (24.2 ± 3.9 arbitrary units (AU)) and W14 (17.9 ± 7 AU) with the highest and lowest wDOMS, respectively. Decreases in wDOMS were reported during the PS. For wFatigue, the highest and lowest values belong to W19 (24.3 ± 3.3 AU) and W32 (16.7 ± 3.9 AU), respectively. In the case of wFatigue, the level increased within the PS. The highest wHI was observed in W19 (88.5 ± 7.7 AU) and the lowest in W32 (72.3 ± 6.1 AU). There were no significant changes between early-PS compared to mid- and end-PS, while significant changes were found for mid-PS in comparison to the end-PS. Changes in wDOMS, wStress, and wFatigue were in line with the changes in Hooper’s scoring. All PS daily monitoring results can provide a great standpoint from which coaches can determine wellness status throughout the season in elite youth level athletes. This information can be used to avoid the risk of injury, overtraining, and non-functional overreaching.

Delayed Onset

This study describes the weekly variations of well-being ratings relative to fatigue (wFatigue), stress (wStress), delayed-onset muscle soreness (wDOMS), sleep quality (wSleep), and Hooper questionnaire (wHQ) throughout the season. In addition, the well-being variables for the playing position in different moments of the season were discussed. Twenty-one elite young soccer players U17 took part in this study. From the beginning of the pre-season, well-being status was monitored daily by the HQ method throughout 36 weeks, including four periods: (1) pre-season, (2) early-season, (3) mid-season, and (4) end-season. Players trained at least 3 times per week throughout the season. The main outcome was that, in weeks 33 and 28, the highest [wFatigue: 15.85 ± 3.38 arbitrary units (AU); wHQ: 48.86 ± 9.23 AU] and the lowest (wFatigue: 5.38 ± 1.88 AU; wHQ: 20.43 ± 5.49 AU) wFatigue and wHQ occurred, respectively, although the lowest level of wDOMS happened in week 28 (4.86 ± 2.15 AU), while the highest wDOMS was observed in week 5 (14.65 ± 4.16 AU). The highest wSleep (13.00 ± 2.12 AU) and wStress (11.65 ± 2.92 AU) were observed in weeks 8 and 34, respectively, while the lowest wSleep (5.81 ± 2.29 AU) and wStress (3.76 ± 0.94 AU) were marked in week 29 coincidentally. In the HQ between every weekday, except recovery day, and the day of the match (MD), considerable highest HQ was only revealed in 2 days after MD in contrast to overall team comparison. In the present study, we observed that the well-being changes between different phases of the season as well as between weeks and days of the week with the MD are significant. These results provide a great point of view for coaches and practitioners about well-being variations over a season in elite youth soccer level. As a result, coaches will be more aware about non-functional overreaching and taking measures to prevent it.

Absolute Effect

Delayed onset muscle soreness (DOMS) is a very common musculoskeletal problem in athletes involved in extreme competitions. The aim of this study is to compare the effect of diathermy, sham diathermy and massage on the knee proprioception of athletes treated for DOMS. Forty athletes were enrolled after the second day of a demanding ski mountaineering race. They were randomly assigned to four groups: no treatment [Formula: see text], massage [Formula: see text], diathermy [Formula: see text], and sham diathermy [Formula: see text]. The knee reposition error was measured after the treatments in order to assess knee proprioception. Significant differences between the diathermy and sham diathermy groups were found ([Formula: see text]) with an absolute effect size of [Formula: see text]. No other significant differences were found among groups. This means that diathermy has a negative impact on joint proprioception and can be explained by the spindle desensitization consequent to deeper tissue heating. This information can be important in the DOMS management of athletes, since an altered proprioception may interfere with the athlete’s performance and can increase the risk of injury.

Significant Difference

The current study surveyed weekly and daily variations of well-being ratings relative to the Hooper Index (HI): fatigue (wFatigue), stress (wStress), delayed onset muscle soreness (wDOMS), and sleep quality (wSleep) during a soccer season based on players’ positions. The full-season was divided into three meso-cycles: Early season, week (W)1 to W7; Mid-season, W8 to W13, and End-season, W14 to W20. Twenty-six young players participated in the study (age, 15.5 ± 0.2 years; height, 172.9 ± 4.2 cm; body mass, 61.4 ± 5.6 kg; body fat, 8.6 ± 2.9%; VO2max, 48.4 ± 2.4 mL.kg−1·min−1; maturity offset, 1.9 ± 0.3 years). Participants played in the same team and competed in Iran national under-16 competitions. Well-being status was monitored on training days using the HI questionnaire. The main result was a significant difference between well-being status 5 days before match day (MD) and 4 days before MD, compared to MD for all playing positions (p ≤ 0.001). The highest and lowest records occurred during End-season for wDOMS (strikers = 11.5 ± 8.4 arbitrary units (AU)), Early season (central defenders = 9.5 ± 0.7 AU) and for wFatigue (central midfielders = 11.4 ± 0.9 AU), and Early season (wide defenders = 9.7 ± 0.7 AU), respectively. Overall, the results showed a significant increase in wStress and wSleep for all players’ positions from Early- to End-season. The main application of this study is to make coaches aware of their players’ well-being fluctuations throughout the full season, especially in young elite soccer players, and to avoid injuries, overtraining, and overreaching as much as possible.

This study aimed to analyze the correlations among weekly (w) acute workload (wAW), chronic workload (wCW), acute/chronic workload ratio (wACWR), training monotony (wTM), training strain (wTS), sleep quality (wSleep), delayed onset muscle soreness (wDOMS), fatigue (wFatigue), stress (wStress), and Hooper index (wHI) in pre-, early, mid-, and end-of-season. Twenty-one elite soccer players (age: 16.1 ± 0.2 years) were monitored weekly on training load and well-being for 36 weeks. Higher variability in wAW (39.2%), wFatigue (84.4%), wStress (174.3%), and wHI (76.3%) at the end-of-season were reported. At mid-season, higher variations in wSleep (59.8%), TM (57.6%), and TS (111.1%) were observed. Moderate to very large correlations wAW with wDOMS (r = 0.617, p = 0.007), wFatigue, wStress, and wHI were presented. Similarly, wCW reported a meaningful large association with wDOMS (r = 0.526, p < 0.001); moderate to very large associations with wFatigue (r = 0.649, p = 0.005), wStress, and wHI. Moreover, wTM presented a large correlation with wSleep (r = 0.515, p < 0.001); and a negatively small association with wStress (r = −0.426, p = 0.003). wTS showed a small to large correlation with wSleep (r = 0.400, p = 0.005) and wHI; also, a large correlation with wDOMS (r = 0.556, p = 0.028) and a moderate correlation with wFatigue (r = 0.343, p = 0.017). Wellness status may be considered a useful tool to provide determinant elite players’ information to coaches and to identify important variations in training responses.

AbstractPurpose. To compare the effects of aquatic and land plyometric training on the vertical jump (VJ) and delayed onset muscle soreness (DOMS) in soccer players. Methods. Twenty-four male soccer players aged 16-18 years (16.53 ± 0.5 years) were randomly divided into three groups: aquatic plyometric training (APT) (n = 8; age: 16.4 ± 0.4 years; body mass: 68.3 ± 7.54 kg; height: 179.75 ± 8.13 cm); land plyometric training (LPT) (n = 8; age: 16.5 ± 0.5 years; body mass: 68.2 ± 7.8 kg; height: 177.0 ± 7.4 cm); and control group (n = 8; age: 16.7 ± 0.6 years; body mass: 61.2 ± 6.5 kg; height: 171.43 ± 5.75 cm), not performing any jump program. An identical training program was applied for 6 weeks, totalling 944 jumps. The VJ was evaluated on a leap jump platform and the Visual Analogue Scale measured the change in DOMS perception. Results. There was a significant increase in the VJ height in both experimental groups (LPT and APT) (p < 0.05). A significant reduction in DOMS perception was verified for the APT group in comparison with the LPT group (p < 0.05) between the first and last week of training. The foot contact time significantly decreased (p < 0.05) in the APT group from pre- to posttest. Significant improvements (p < 0.05) were observed in the flight time and jump speed from pre- to post-test in both LPT and APT groups. Conclusions. APT can increase the VJ height and reduce DOMS perception in soccer players.
