- Are male soccer players accumulating sufficient load across varying microcycle structures? Examining the load, wellness and training/match ratios of a professional teamPublication . Oliveira, Rafael; Canário-Lemos, Rui; Morgans, Ryland; Peixoto, Rafael; Vilaça-Alves, José; BRITO, JOÃO PAULOProfessional soccer involves varying numbers of training sessions and matches each week, which can influence load distribution. Understanding the exact distribution may allow appropriate load periodisation and planning for players. Thus, this study aimed to (i) compare accumulated load and wellness between weeks with different numbers of training sessions and (ii) compare training/match ratio (TMr) of external and internal load between weeks with different numbers of training sessions. Ten players with a minimum of 45 minutes of weekly match-play were analysed over 16 weeks. The microcycle structures consisted of three (3dW), four (4dW), five (5dW) and six (6dW) training sessions plus match-day per week. The following measures were used for analysis: duration, fatigue, quality of sleep, muscle soreness, stress, mood, rating of perceived exertion (RPE), session-RPE (s-RPE), high-speed running distance (HSR), sprint distance (SPD), number of accelerations (ACC) and decelerations (DEC). Accumulated wellness/load were calculated by adding all training and match sessions, while TMr was calculated by dividing accumulated load by match data. The main results showed that accumulated wellness and load were significantly different, with moderate to very large effect sizes, except regarding mood, duration, s-RPE, SPD during 5dW vs. 6dW and s-RPE, HSR, SPD, ACC and DEC during 3dW vs. 4dW (all p > 0.05). Moreover, 6dW was significantly higher than 4dW regarding TMr of duration (p < 0.05, moderate effect size), RPE, HSR and SPD (all p < 0.05 with very large effect sizes) and for 3dW of HSR and ACC (p < 0.05 with very large effect sizes). This study showed that 5dW and 6dW had higher training measures than 3dW or 4dW. Additionally, higher wellness was presented in the microcycles with higher training frequencies. These findings suggest that physical load and wellness were not adjusted according to the number of training sessions within a microcycle.
- Drop set versus traditional strength training protocols equated in volume on muscle thickness in womenPublication . Vilaça-Alves, José; Brito, João; Machado, Beatriz; Canário-Lemos, Rui; Moreira, Tiago; Matos, Filipe; Peixoto, Rafael; Monteiro, Gabriéla; Garrido, Nuno; Casanova, Filipe; Costa, Pablo; Reis, Victor MachadoPurpose The aim of this study was to investigate the effects of two strength training protocols, equated in volume, on the elbow flexor muscle thickness (MT) in women. Methods Twenty-seven women (mean±sd, age 21.89±2.85 years; stature,167.82±5.90 cm; body mass 63.01±7.20 kg; estimate of body fat mass, 19.19±2.88%) were divided in three experimental groups: a drop-set (DS), a traditional (TR), and a control group (CG). The CG maintained regular strength training without perform any upper body exercises. The participants performed a dumbbell biceps curl for two days per week for 12 weeks 4 sets of 3 blocks of 10 repetitions at 75%, 55%, and 35% of their 1 Repetition Maximum (RM) for the DS group, and 8 sets of 11 repetitions at 75% of the 1RM for the TR protocol. Rest interval between sets was 120 seconds for both groups. The MT was acquired in the anterior face of both upper arms at 50% and 60% of the distance between the lateral epicondyle of the humerus and the acromial process of the scapula before (T0) and after the 24 training sessions (T1). Results There was a significant increase in all MT measurements between T0 and T1for the training groups(p<0.05). In addition, significantly higher values of MT were found in the training groups compared to the control group for all local measurements in T1 (p<0.05). No significant differences were found between training the groups for MT. Conclusion It appears that both training groups (DS and TR), were effective in promoting MT of the elbow flexors muscles of young women with no differences between training strategies.
- The relationship between wellness and training and match load in professional male soccer playersPublication . Oliveira, Rafael Franco Soares; Canário-Lemos, Rui; Peixoto, Rafael; Vilaça-Alves, José; Morgans, Ryland; Brito, JoãoThe aims of this study were to: (i) analyse the within-microcycle variations in professional soccer players; (ii) analyse the relationships between wellness and training and match load demands; (iii) analyse the relationships between match-day (MD) demands and wellness during the following day (MD+1); and (iv) analyse the relationships between MD and wellness during the day before match-play (MD-1). Thirteen professional soccer players (age: 24.85±3.13 years) were monitored daily over 16-weeks for wellness and training and match-play intensity. The daily wellness measures included fatigue, quality of sleep, muscle soreness, mood and stress using a 1–5 scale. Internal intensity was subjectively measured daily using the rating of perceived exertion (RPE) and the multiplication of RPE by session duration (s-RPE). While external intensity was quantified utilising high-speed running, sprinting, and acceleration and deceleration metrics. Data was analysed from each training session before (i.e., MD-5) or after the match (i.e., MD+1). Repeated measures ANOVA or Friedman ANOVA was used to analyse the aims (i) where Spearman correlation was applied to analyse the relationships between the aims (ii) and (iii) between sleep quality and training intensity. The main results for aim (i) showed that MD+1 presented the lowest values for wellness variables (p < 0.05). While MD-1 presented the lowest internal and external load values (for all variables), with MD presenting the highest values (p < 0.05). Regarding aim (ii), the main result showed significant large negative correlations between fatigue and s-RPE (r = -0.593; p = 0.033). Considering aim (iii), significant small to very large negative correlations were found for sleep quality, fatigue and muscle soreness with all internal and external variables (p < 0.05). Lastly, the main results for aim (iv) showed large negative correlations for fatigue and session duration; fatigue and s-RPE; muscle soreness and session duration; muscle soreness and s-RPE; and muscle soreness and decelerations (p < 0.05, for all). The main conclusions were that MD had an influence on wellness and internal and external training intensity, notably MD-1 and MD+1 were most affected. In this regard, a tendency of higher internal and external intensity on MD was associated with lower wellness measures of sleep quality, muscle soreness and fatigue on MD+1.
