This study aimed to define the movement analysis and metabolic model in tennis on hard courts and clay courts. Twenty-four tennis players were equipped with a 15 Hz GPS and a Polar. H7 and played a match on each playing surface. The average duration of matches was 76 A} 24 (C) and 69 A} 17 min (H). The maximum heart rate (HRmax) was 185 A} 14 (C) and 178 A} 10 bpm (H), the average heart rate (HRav) was 144 A} 14 (C) and 139 A} 12 bpm (H). The average metabolic power (MPav) was 3.93 A} .34 (C) and 3.70 A} .34 W A~ kg−1 (H) (ES = .72, C > H, +6%). The ANOVA and the post hoc showed significant differences regarding the considered parameters on both the surfaces. The t-test highlighted significant surface-related differences (ES = .88, C > H, +26%) concerning accelerations performed between 50 and 60% of the maximum value, decelerations between 40 and 50% of the maximum (ES = 1.28, H > C, +37%), metabolic power between 0 and 10 W A~ kg−1 (ES = .71, H > C, +1%), and 10 and 20 W A~ kg−1 (ES = .78, C > H...

This research aims to investigate the direct and indirect effects of physical training on psychological health in a sample of individuals with Multiple Sclerosis (MS). Thirty-five women affected by relapsing-remitting MS, with a mean age of (40 ± 5) years and an Expanded Disability Status Scale (EDSS) score ranging between 0 and 3, participated in the study. After baseline tests, in accordance with pairing techniques, participants were assigned to an experimental (EG) and a control group (CG). The EG attended a 12-week combined aerobic and strength program. Those in the EG and the CG were homogeneous at baseline and were treated similarly except for the intervention. Participants of both groups were tested before and after the intervention with the following instruments: 1. Modified Fatigue Impact Scale (MFIS); 2. Beck Depression Inventory scale (BDI); 3. Multiple Sclerosis Quality of life–54 (MSQOL-54). Data was analyzed with non-parametric tests for unpaired samples, linear regression and mediation analysis. The results showed: (a) the benefits of physical training on the perception of fatigue, depression, social activity and Quality of Life (QoL) in the EG; (b) the role of fatigue as a mediator of the relationship between participation in physical training and depression, social activity and QoL. Findings suggested the effectiveness of a combined aerobic and strength training for the improvement of psychological aspects in women affected by MS and the mediation role of fatigue in such a relationship.
