The role of physical activity in improving overall aspects of health regardless of age is well documented. Due to the coronavirus disease 2019 outbreak, preventive measures to limit airborne infection have been introduced, with people, especially older adults, advised to stay at home, thus increasing sedentary lifestyle and the risk of chronic diseases. As one of the few possible ways to stay active is home-based training, this review aims to provide evidence on alternative and feasible home-based activity programs as a tool to improve the fitness level in older adults, especially when preventive measures are needed to ensure isolation and limit interpersonal contacts. During quarantine, older adults, especially those with chronic diseases, are recommended to regularly exercise. Combined balance and muscle-strengthening training has proven to be particularly useful in limiting falls and mobility limitations. In addition, the use of virtual reality systems seems to be a potential strategy in remaining physically active, reducing physical inactivity time and significantly increasing the compliance of the older adults with physical activity programs. In conclusion, home-based programs induce improvements in physical functions in general and quality of life in older people with or without co-morbidities, and it can be considered in the future as one of the feasible and economic ways to increase physical well-being. This may be of unique importance in the setting of coronavirus disease 2019 enforced limitations in out-of-home activity.

This study aimed to evaluate whether the type and degree of physical activity commitment (i.e., team sport athletes, highly active individuals, sedentary behavior) influence body image and exercise behavior. A total of 96 participants (46 women and 50 men; age: 22.7 ± 2.7 years; height: 170 ± 8.6 cm; weight: 67.6 ± 10.8 kg) were divided in six groups: female volleyball and male football players (student athletes classified as Tier 2), highly physically active women and men, with high sitting time completed the Body Image Dimensional Assessment and the 21-item Exercise Dependence Scale to evaluate body dissatisfaction and level of dependency on exercise. The Body Image Dimensional Assessment is a silhouette-based scale, where three direct indices are derived from the participants’ responses: body dissatisfaction, sexual body dissatisfaction, and comparative body dissatisfaction. The Exercise Dependence Scale is a six-point Likert scale that evaluates seven dimensions of exercise dependence (tolerance, withdrawal, intention effects, lack of control, time, reductions in other activities, and continuance) and provides an overall score. A multivariate analysis of variance was used to examine the effects of different levels of physical activity, team sport participation (volleyball and football), and sedentary behavior (i.e., high sitting time) on participants’ body image indices and dimensions of exercise dependence according to sex. Volleyball players showed significantly higher body dissatisfaction than football players (d = 0.99) and the physically active men group (d = 2.31), who had lower values than sedentary women group (d = 1.68). Football players had lower comparative body dissatisfaction values than volleyball players (d = 1.70) and sedentary women (d = 1.69), who had higher values than sedentary men (d = 1.04). Sedentary women had a significantly lower exercise dependence scale score than volleyball players (d = 1.71), football players (d = 1.12), and physically active men (d = 1.21). The findings highlight the impact of regular physical activity on body dissatisfaction and the variance in body image perceptions between the sexes. Moreover, the high exercise dependence values found in volleyball and football players and physically active men suggest an effect of intense training and maladaptive exercise behaviors, underlining the need for comprehensive strategies to address exercise dependence.

Inter-limb asymmetry is defined as the performance imbalance of a limb with respect to the other one. Studies demonstrated how plyometric training could minimize inter-limb imbalance by reducing asymmetries and the relative risk of musculoskeletal injuries. Among the different plyometric training modalities, SuperJump^® represented a reliable method. This study aimed to evaluate the acute effects of SuperJump^® training on dynamic balance Unilateral Asymmetry and Bilateral Asymmetry Indexes. Thirty-seven subjects were randomly allocated in two groups: SuperJump^® (N = 20) and Control (N = 17). The SuperJump^® group participated in the SuperJump^® session, whereas the Control group did not receive any workout session. Before (PRE) and after (POST) the SuperJump^® session, both groups performed the Wobble Board balance test. A significant difference (p < 0.003) between the SuperJump^® in POST and Control groups in PRE intervention for dominant leg was found. No significant differences (p > 0.05) emerged between groups in testing time on Bilateral Asymmetry Index. Significant differences (p = 0.005) between PRE and POST in the SuperJump^® group and an 18.9% Unilateral Asymmetry Index threshold reduction for the subjects were found. A strong relationship (R² = 0.79) between delta (∆) change Unilateral Asymmetry Index and Unilateral Asymmetry Index baseline parameters was tested. Lastly, no significant differences (p > 0.05) in Unilateral Asymmetry Indexes between the Bilateral Asymmetry equal and change categories in the SuperJump^® group was found. In conclusion, SuperJump^® training played a key role in reducing Unilateral Asymmetry Index.

The purpose of this study was to evaluate the acute effects of a mini trampoline training session (SuperJump^®) on leg stiffness and reactive power (R_P) while examining its relation to participants’ sex. A total of 20 participants (11 females, age: 24.4 ± 1.0 yrs; 9 males, age: 27.3 ± 2.9 yrs) performed continuous jump repetitions (RJs), measured on a force plate, before (PRE) and after (POST) a 30 min Superjump^® session. Linear repeated measures mixed models were used to examine the effects of the Superjump^® session on the leg stiffness mean (K_MEAN), mean of the best RJs (K_BEST), and R_P in relation to sex. Before and after the mini trampoline training session, females showed lower K_MEAN and K_BEST values compared with males. Despite the significant (p < 0.002) decreases in R_P after the Superjump^® session in both males (PRE: 23.1 ± 6.5 W/kg; POST: 21.2 ± 6.1 W/kg) and females (PRE: 23.6 ± 5.5 W/kg; POST: 21.9 ± 5.3 W/kg), leg stiffness remained unchanged, suggesting a potential protective effect of mini trampoline training on leg stiffness during acute adaptations. These findings suggest that Superjump^® training might exert a protective effect on leg stiffness, which prevents acute decreases that are commonly observed in other training modalities. The sex-related differences emerging from the present study emphasize the need for personalized approaches when integrating this innovative training tool into athletes’ regimens.

Background: Student-athletes face the dual challenge of balancing academic and athletic commitments, which may simultaneously promote healthy lifestyle habits while increasing psychosocial and physiological stressors, particularly among female student-athletes. Understanding how these competing demands affect key behavioral (e.g., dietary habits, sleep, and chronotype) and psychological (e.g., body image) factors is essential for supporting their overall well-being. Therefore, this cross-sectional study investigated body dissatisfaction, adherence to the Mediterranean diet, sleep quality, and chronotype in female student-athletes compared to sedentary peers. Methods: Twenty-eight female participants voluntarily participated in the study. Twelve volleyball student-athletes (age 21.6 ± 2.4 years) were assessed during their competitive in-season period, and sixteen non-athlete students with a high sitting time (age 24.0 ± 3.2 years) completed the Mediterranean Diet Adherence questionnaire (PREDIMED), Pittsburgh Sleep Quality Index (PSQI), Morningness–Eveningness Questionnaire (MEQ), and Body Image Dimensional Assessment (body dissatisfaction) to assess their overall well-being. Results: Student-athletes showed significantly (p < 0.05) higher adherence to the Mediterranean diet (PREDIMED: 8.5 ± 1.5 score), although experiencing poorer sleep quality (PSQI: 6.8 ± 3.0 score) compared to non-athlete students with higher sitting times (PREDIMED: 6.7 ± 1.6 score; PSQI: 4.6 ± 2.3 score). Conversely, comparative body dissatisfaction was significantly higher in non-athlete students with a high sitting time (19.4 ± 24.5%) than in student-athletes (5.6 ± 10.5%). No significant differences emerged for chronotype or overall body dissatisfaction. Conclusions: These findings highlight a paradoxical health pattern in female student-athletes who combine healthier eating habits with poorer sleep quality. The results emphasize the importance of comprehensive wellness strategies that integrate dietary habits, sleep hygiene, and psychophysiological factors to better support female student-athletes in managing dual-career demands.

Anthropometrics and sex influence balance performances, and visual information can change anthropometrics’ relation and the postural sway. Therefore, the aim of the present study was to evaluate the effect of anthropometric characteristics, sex, and visual biofeedback and/or their interaction on a computerized wobble board. Twenty-seven (14 females, 13 males) young adults performed three 30-s double leg stance trials on a wobble board during two conditions: with visual and without visual biofeedback. Visual biofeedback improved (p = 0.010) balance on a wobble board with respect to the condition without visual biofeedback. Regardless of sex, no differences between conditions were found (p = 0.088). When investigating the effect of anthropometrics variables, sex, and their interactions on conditions, a significant main effect of the lower limb/height ratio, sex, and their interaction on the condition without visual biofeedback was found (p = 0.0008; R² = 0.57). For the visual biofeedback condition, significant effects for sex and body mass (p = 0.0012; R² = 0.43) and sex and whole-body moment of inertia (p = 0.0030; R² = 0.39) were found. Results from the present study showed (1) visual biofeedback improved wobble board balance performance; (2) a significant main effect of lower limb/height ratio, sex, and their interaction on the wobble board performances without visual biofeedback emerged; (3) significant effects were found for sex and body mass and sex and moment of inertia in the visual biofeedback condition. Findings from the present study could have an impact on training and evaluations protocols, especially when several populations such as children, athletes, older adults and people with balance disorders are involved.
