Background: Evidence supporting the effectiveness of aerobic training, specific for fatigue, in severely fatigued patients with multiple sclerosis (MS) is lacking.

Objective: To estimate the effectiveness of aerobic training on MS-related fatigue and societal participation in ambulant patients with severe MS-related fatigue.

Methods: Patients ( N = 90) with severe MS-related fatigue were allocated to 16-week aerobic training or control intervention. Primary outcomes were perceived fatigue (Checklist Individual Strength (CIS20r) fatigue subscale) and societal participation. An improvement of ⩾8 points on the CIS20r fatigue subscale was considered clinically relevant. Outcomes were assessed by a blinded observer at baseline, 2, 4, 6 and 12 months.

Results: Of the 89 patients that started treatment (median Expanded Disability Status Scale (interquartile range), 3.0 (2.0-3.6); mean CIS20r fatigue subscale (standard deviation (SD)), 42.6 (8.0)), 43 received aerobic training and 46 received the control intervention. A significant post-intervention between-group mean difference (MD) on the CIS20r fatigue subscale of 4.708 (95% confidence interval (CI) = 1.003-8.412; p  = 0.014) points was found in favour of aerobic training that, however, was not sustained during follow-up. No effect was found on societal participation.

Conclusion: Aerobic training in MS patients with severe fatigue does not lead to a clinically meaningful reduction in fatigue or societal participation when compared to a low-intensity control intervention.

Background: The worldwide rise in the prevalence of noncommunicable diseases has increased the recognition of the need to identify modifiable risk factors for preventing and managing these diseases. The office worker, as a representative group of physically inactive workers, is exposed to risk factors for metabolic syndrome, which is a primary driver of noncommunicable diseases. The use of virtual reality (VR) exergames may offer a potential solution to the problem of increasing noncommunicable disease prevalence, as it can help individuals increase their physical activity levels while providing a more immersive experience.

This study examines the acute effects of post-activation performance enhancement (PAPE) with different loads (84% and 60% 1-RM) and exercises (hip thrust; HT and glute bridge; GB) on sprint performance (SP) and horizontal force-velocity (HF-V) profile components in adolescent male soccer players. The participants were randomly assigned to three groups: hip thrust group (HTG; n = 13), glute bridge group (GBG; n = 13), and control group (CG; n = 14). Sprint tests at distances of 10, 20, and 30 m were conducted pre-PAPE and post-PAPE protocols with a 7 min rest period.

Objectives: Many studies draw attention to the negative consequences of the pandemic or lockdown on the well-being and lifestyle of different sections of the population. This study considers whether changes occurred in dietary regime and level of physical activity during three periods - before the pandemic, during the lockdown, and during the present in older Slovak adults. We also investigate whether individual weights changed during the pandemic.

Background: A small number of reviews have explored lower- versus higher-volume training in non-athletes, but the growing challenge of congested schedules in team sports highlights the need to synthesize evidence specific to team sport athletes. Thus, the objectives of this systematic review with meta-analysis are twofold: (i) to summarize the primary physiological and physical fitness outcomes of lower-volume versus higher-volume training interventions in team sports players; and (ii) to compare the effects of lower-volume training with higher, considering the training modalities used.

Methods: We conducted searches across key databases, including PubMed, Scopus, SPORTDiscus, and Web of Science.

The collective detrimental impact of aged naive lymphocytes and thymus atrophy on the aging of the immune system can be mitigated by exercise. Hence, this research aims to explore the effects of three methods of water-based exercises on immune system aging and thymus atrophy in elderly rats. Thirty-two 24-month-old rats, with an average weight of 320 ± 5 g, were randomly allocated into four groups of endurance training (n = 8), resistance training (n = 8), combined training (n = 8), and control (n = 8).
