The object of the study was to identify the relationship between the motivation for physical activity, the physical activity index (PAI), and the body mass index (BMI) for a sample of university students, taking into consideration the gender difference. The study subjects were 813 (340 men and 473 women), and the age range of the participants varied between 18 and 25 years. The RM 4-FM (Motivation for Physical Activity and Exercise) and PAI online questionnaires were applied to measure the motivation and the physical activity level. The study’s novelty focused on analyzing how intrinsic and extrinsic motivation interact and correlate BMI and physical activity levels (PAI). Regarding gender, we approached the identification of motivational differences and the level of physical activity of students from non-sports faculties to identify relevant aspects for promoting proactive behaviors. Results revealed significant gender differences: men had a higher PAI (53.48 ± 28.11) than women (36.67 ± 23.92, p < 0.01); BMI (23.25 vs. 21.69, p < 0.01). The Cohen’s value of RAI of RM 4-FM, BMI, and PAI were > 0.5, indicating a large effect size. The analysis presents a unique perspective of the interactions between psychological factors, motivation, and physical characteristics, providing insight into developing strategies to improve and promote a proactive lifestyle.

The present study aimed to investigate the effects of a 12-week Core Stability Training (CST) program on trunk mobility (twisting and bending), upper quarter dynamic balance (UQ-YBT scores), and postural asymmetry indices (Anterior—ATSI—and Posterior Trunk Symmetry Indices—POTSI) of university students. This study examined the effects of a 12-week CST program on trunk mobility and dynamic balance in 181 university students (70 females, 111 males; aged 18–24 years). Participants completed one supervised 90–100-min session per week. Baseline postural symmetry, assessed with the ATSI and POTSI, showed no sex differences. After training, trunk mobility improved significantly (p < 0.001). The female group increased twisting by 5.3° and bending by 6.5 cm, while the male group improved by 4.7–6.1° and 6.0–6.1 cm, respectively (η² = 0.625–0.773). Dynamic balance measured by the UQ-YBT also improved in all directions (p < 0.001). Mean gains ranged from 4.0 to 9.7 points, with large effect sizes, especially in males (η² up to 0.842). CST effectively enhanced trunk mobility and upper trunk stability in both sexes. Although postural asymmetry did not change, the program improved neuromuscular control and balance, demonstrating its value in promoting postural health among university students.

Background/Objectives: In Romania, therapeutic program programs for children with autism spectrum disorder (ASD) focus mainly on behavioral and educational approaches, with limited integration of adapted physical activity (APA). Therapeutic swimming may provide complementary benefits, addressing both physical and psychosocial challenges. This study explored parent-perceived changes across an adapted therapeutic swimming program, following ABA therapy, on the well-being, learning, attention, physical activity, and social functioning of children with ASD. A custom-developed parent-report tool (PPQ-Autism-Swim) was used to measure perceived changes across key developmental domains. Methods: Thirty-nine children with ASD were recruited, of whom 36 completed the full 8-week swimming intervention. Parent-report questionnaires, developed by behavioral therapists under the supervision of a clinical psychologist, were administered at three time points: 8 weeks before swimming (T − 8), immediately before swimming after Applied Behaviour Analysis (ABA) therapy (T0), and 8 weeks after swimming (T + 8). The questionnaire assessed five subscales: general well-being, physical activity and energy, attention and focus, learning and cognitive progress, and self-confidence and social behaviors. Data were analyzed using descriptive statistics, repeated-measures ANOVA, and thematic analysis of qualitative parental feedback. ABA therapy served as a behavioral baseline, allowing comparison with subsequent gains from swimming. Results: Parents reported higher scores across time points, suggesting perceived changes in several domains. From T − 8 to T0, moderate gains followed ABA therapy, while from T0 to T + 8, therapeutic swimming was associated with improvements. At T + 8, 35 of 36 children showed measurable progress, particularly in physical activity regulation and self-confidence. Parental feedback emphasized calmer behavior, improved sleep, increased social interaction, and greater pride in new skills. Reliability testing indicated good to excellent internal consistency (Cronbach’s α = 0.78–0.91). Conclusions: Therapeutic swimming appears to be an effective and motivating form of adapted physical education, complementing behavioral therapies and addressing multiple developmental challenges in children with ASD.

Introduction: This study investigated heart rate variability (HRV) and perceived recovery status (PRS) in relation to sprint performance in competitive athletes involved in sprint events. A secondary aim was to explore potential gender-based differences in these relationships. Methods: Fifty-six sprint-trained athletes (21 males, 35 females; age 16–21) participated in a 5-day in-season microcycle. Daily morning HRV was measured using Polar H10 chest straps and the HRV4Training app, with the root mean square of successive differences (LnRMSSD) used as the primary HRV marker. Perceived recovery was assessed each morning using the PRS scale. On each day, athletes completed 20 m maximal sprint tests. Linear mixed-effects models were used to examine the relationships between LnRMSSD, PRS, gender, and sprint performance while accounting for repeated measurements within athletes. Results: Linear mixed-effects modeling revealed that LnRMSSD was a significant negative predictor of sprint time (β = −0.019, p = 0.003), indicating that higher parasympathetic activity was associated with faster sprint performance. PRS was also a significant negative predictor of sprint performance (β = −0.014, p = 0.008). Conclusions: Daily recovery markers were associated with sprint performance in competitive sprint athletes, with potential gender-specific patterns that should be interpreted cautiously. Both LnRMSSD and PRS were significantly associated with sprint performance, highlighting the relevance of combining physiological and subjective recovery markers in athlete monitoring.

Bilateral morphological asymmetry of the upper limbs may influence grip strength even in semi-active young adults. Understanding this relationship is important for identifying early neuromuscular imbalances with implications for ergonomics and rehabilitation. This study aimed to examine associations between upper limb anthropometric characteristics and grip strength in non-athlete students, considering gender and manual dominance. The sample included 192 healthy university students (110 females, 82 males; mean age 19.92 ± 1.4 years) without prior sports training. Thirteen bilateral anthropometric parameters of the upper limbs were assessed, including hand and palm dimensions, segmental lengths, and arm and forearm circumferences, along with grip strength measured by dynamometry in two positions: arm extended and arm flexed at 90°. Statistical analysis revealed significant differences in forearm length, arm and forearm circumferences, and grip strength (p < 0.001). The dominant limb consistently demonstrated higher grip strength, with mean differences of approximately 2 kg. Male participants showed higher absolute values for all morphological and functional variables, whereas stronger correlations between distal upper-limb morphology and grip strength were observed in females. These findings indicate that, despite largely symmetric skeletal dimensions, moderate functional asymmetries exist and grip strength is influenced primarily by local muscular development rather than overall limb size.

Background: This study examined the relationship between gamification experience, fitness performance, and physical activity patterns according to gender. Methods: A total of 622 students aged 13–14 years (52.1% boys, 47.9% girls) completed a six-week gamified PE program via the Sworkit platform, integrating progress tracking, digital rewards, and challenge-based progression into three weekly instructor-led sessions. Fitness was measured pre- and post-intervention using the Youth Fitness International Test (YFIT) battery—BMI, 20 m shuttle run, handgrip strength, and standing long jump. Gamification experience was assessed with the Gamification User Experience Scale (GAMEX), and the Y-PATHS framework was applied to classify physical activity patterns. Results: Significant improvements were observed across all physical fitness indicators following the six-week gamified intervention. The largest gains occurred in the 20 m shuttle run (Δ = +4.3; F = 48.22; p < 0.001; η² = 0.60) and handgrip strength (Δ = +2.6; F = 39.74; p < 0.001; η² = 0.51), indicating substantial improvements in aerobic and muscular fitness. Standing long jump also showed notable progress (Δ = +7.7 cm; F = 35.12; p < 0.001; η² = 0.48), while BMI decreased modestly but significantly (Δ = −0.3; F = 7.85; p < 0.001; η² = 0.55). Overall, the ANOVA confirmed significant pre–post changes across all domains (p < 0.01; η² = 0.41–0.62). Higher GAMEX scores correlated strongly with total fitness gains (r = 0.54; p < 0.001) and predicted performance improvement (R² = 0.29). Conclusions: Gamified PE can enhance both fitness performance and physical activity patterns, with clear gender-specific trends. Integrating YFIT, GAMEX, and Y-PATHS offers a comprehensive framework for designing targeted, effective PE programs for adolescents.
