The 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.
The aim of this study was to verify and compare the effects of electromyostimulation training (EMS), strength training (ST), and both combined (STEMS), through the analysis of the elbow flexors muscle thickness. Forty subjects (24.45 ± 3.53 years), were randomly divided equally in 4 groups: 3 experimental groups and 1 control group. Each experimental group was submitted to one of three interventions, either an ST protocol, an EMS protocol, or a STEMS protocol. The control group (CG) did not perform any type of physical activity. Ultrasonography (US) was used to measure muscle thickness (MT) at 50 and 60% of the distance between the acromion and the olecranon. The results showed a significant difference in the elbow flexors muscle thickness after 8 weeks, both in the STG, EMSG, and STEMSG, but not in the CG. However, no significant differences were observed between the intervention protocols. It seems that an increase in MT can be obtained using either with ST, EMS, or both combined, however, the results doesn’t support the overlap of one method in relation to the others. EMS can be another interesting tool to induce muscle hypertrophy, but not necessarily better.
Indoor cycling’s popularity is related to the combination of music and exercise leading to higher levels of exercise intensity. It was our objective to determine the efficacy of heart rate and rating of perceived exertion in controlling the intensity of indoor cycling classes and to quantify their association with oxygen uptake. Twelve experienced males performed three indoor cycling sessions of 45 min that differed in the way the intensity was controlled: (i) oxygen uptake; (ii) heart rate; and (iii) rating of perceived exertion using the OMNI-Cycling. The oxygen uptake levels were significantly higher (p = 0.007; μp2 = 0.254) in oxygen uptake than heart rate sessions. Oxygen uptake related to body mass was significantly higher (p < 0.005) in the oxygen uptake sessions compared with other sessions. Strong correlations were observed between oxygen uptake mean in the oxygen uptake and rating of perceived exertion sessions (r =0.986, p < 0.0001) and between oxygen uptake mean in the oxygen uptake and heart rate sessions (r = 0.977, p < 0.0001). Both heart rate and rating of perceived exertion are effective in controlling the intensity of indoor cycling classes in experienced subjects. However, the use of rating of perceived exertion is easier to use and does not require special instrumentation.
Background: This research explored how tele-exercise influenced physical fitness and mental well-being in individuals with and without disabilities and with different training habits. Methods: One hundred and ninety-three participants were categorized into two groups: athletes and non-athletes. Participants were involved in either synchronous or asynchronous tele-exercise programs of two or three sessions of workouts per week, lasting eight weeks. Psychological well-being was evaluated pre- vs. post-intervention by the WHO-Five Well-Being Index (WHO-5), Psychological General Well-Being Index (PGWBI), and Perceived Stress Scale (PSS-10). Fitness assessment tools included the 2-minute step test, curl-up test, forward bending test, and squat test. Body weight was also assessed pre- and post-intervention. Results: The analysis showed a significant increment in all fitness scores (p-value ranged from <0.001 to 0.015) with no change in body weight. Psychological tests indicated an overall increment in the participants’ well-being measured by the WHO-5 and unexpectedly, also in the stress level assessed through PSS-10. Conclusions: Enabled by technology, tele-exercise provides a flexible and convenient complementary approach to conventional workouts, helping individuals maintain an active lifestyle and improve their well-being. Positive effects on the sedentary population’s lifestyles are discussed.
Purpose: 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 DS group performed a dumbbell biceps curl for two days/week, 12 weeks, 4 sets of 3 blocks of 10 repetitions at 75%, 55%, and 35% of their 1 Repetition Maximum (RM), and 8 sets of 11 repetitions at 75% of the 1RM for the TR protocol. Rest interval between sets was 120 seconds. 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.

Breast cancer (BC) is the most common cancer among women, with an incidence of 85–94 per 100,000 people annually in Europe. Despite the increasing incidence of BC, advancements in early detection and novel therapeutic approaches have improved survival rates. However, adjuvant treatments are associated with side effects, including a reduction in the left ventricular ejection fraction (LVEF), which can result in severe cardiac damage and progress to heart failure. Methods: Thirty-eight women undergoing BC treatment were included in the study. Eighteen women (47.2 ± 5.4 years old) participated in a supervised physical exercise (PE) program for 60 min/day, twice weekly, at moderate to high intensity (5 min joint mobilization, 20 min predominantly aerobic training, 30 min of strength training, and 5 min cooldown). The remaining 20 women (51.5 ± 9.5 years) were advised to remain active during treatments, but without specific supervision. In the PE group, a slight reduction in the LVEF was observed after chemotherapy (63.73 ± 3.34% vs. 61.00 ± 6.54%, p = 0.131). In contrast, the control group showed a statistically significant reduction in the LVEF (64.93 ± 4.00% vs. 60.57 ± 4.86%, p = 0.008). Although the results suggest a potential protective effect of regular physical exercise during BC treatment, the study was inconclusive regarding its role in preventing cardiac dysfunction. Further research with a larger sample size and longer follow-up is warranted.
