Special Issue Information

Dear Colleagues,

Exercise is a cornerstone of physical health, influencing a wide array of bodily functions and characteristics. From enhancing muscle strength and cardiovascular fitness to preventing eye disease and improving bone density and metabolic health, exercise plays a pivotal role in shaping our physical attributes.

We are pleased to invite you to contribute studies that delve into the physiological, biomechanical, and morphological changes induced by different types of exercise regimens. The aim of this Special Issue is to explore the multifaceted impacts of various exercise modalities on the human body, encompassing both the general population and specific groups such as athletes, older adults, and individuals with chronic conditions. We seek to gather multidisciplinary, innovative research and comprehensive reviews that delve into the physiological, biomechanical, and morphological changes prompted by physical activity. By highlighting cutting-edge research and fostering interdisciplinary dialogue, this Special Issue aspires to deepen our understanding of how exercise interventions can be optimized to enhance physical health and performance.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the role of exercise under the following parameters:

  1. Muscle hypertrophy and bone density;
  2. Eye health;
  3. Cardiovascular health;
  4. Metabolic adaptations;
  5. Visual adaptations;
  6. Sports vision;
  7. Mitigating age-related physical decline.

We look forward to receiving your contributions.

This study aimed to investigate the relationship between visual system parameters (visual acuity and refractive error) and postural balance under controlled conditions in elite football players. Visual acuity (monocular and binocular) and refractive errors were assessed in 34 male athletes using retinoscopy and subjective refraction. Postural stability was assessed with the Cyber-Sabots™ platform, recording the center of pressure (CoP) metrics, including sway amplitude, velocity, and distribution area. Visual and postural parameter correlations were assessed using Pearson’s test (p < 0.05). Athletes demonstrated good binocular visual acuity (−0.03 ± 0.09 logMAR) and were predominantly emmetropic. Visual acuity and postural parameters showed significant negative correlations, whereby visual acuity was associated with reduced CoP displacement (r = −0.352) and sway area (r = −0.367), indicating enhanced stability. Hyperopia and oblique astigmatism were moderately correlated with increased sway (r = 0.343) and antero-posterior sway amplitude in the sagittal plane (r = 0.324). Anisometropia showed moderately negative correlations with antero-posterior control (r = −0.421), suggesting a disruptive effect on postural stability. The postural analysis showed adaptations characteristic of football players, including anterior body inclination, increased forefoot loading, and medio-lateral sway. Romberg’s quotients highlighted significant visual input reliance for maintaining postural balance. Visual acuity, refractive errors, and interocular refractive asymmetries significantly influence postural stability in elite football players. These results support incorporating visual function assessment into training and injury prevention in elite sports. Full article

Effective mass, the portion of an athlete’s mass contributing to a punch, is a key biomechanical factor influencing punching strength in boxing. This study examines its relationship with punch mechanics, impulse dynamics, and body composition, identifying techniques that maximize effective mass and enhance force transfer efficiency. Thirty trained male boxers performed jab, cross, lead hook, and rear hook punches while punching force and limb acceleration were measured using an AMTI MC12-2K force plate and Noraxon Ultium EMG sensors. Effective mass was calculated as the ratio of peak force to fist acceleration at impact. Statistical analysis compared punching techniques and examined correlations with body composition and training experience. Straight punches (jab, cross) exhibited significantly higher effective mass than hooks (KW-H = 235.24; p < 0.001; η2 = 0.468), despite hooks generating greater peak forces. Cross punches had the highest effective mass (31.17 ± 16.20 kg), followed by jabs (30.39 ± 15.09 kg). No significant correlation was found between effective mass and body composition or training tenure, suggesting technique is more critical than absolute body mass. These findings highlight the importance of optimizing linear punch mechanics and impulse-to-acceleration synchronization in training to enhance effective mass transfer and striking performance.

This study aimed to investigate the effectiveness of low-load high-volume (LL-HV) resistance training compared to traditional high-load low-volume (HL-LV) protocols in eliciting functional and structural adaptations in powerlifters. Twenty-six well-trained male powerlifters were randomly assigned to LL-HV and HL-LV groups and participated in a 12-week supervised training intervention. The LL-HV protocol involved an initial bench press set performed at 45–60% of one-repetition maximum (1RM), with very high repetitions, while the HL-LV group performed the initial set at 75–90% of 1RM, following matched total training volume for accessory exercises. Both groups trained twice weekly, with identical proximity to failure based on repetitions in reserve (RIR). Functional outcomes included changes in bench press 1RM and mean velocity (MV) measured at various submaximal loads, while structural adaptations were assessed through arm and chest circumferences. Statistical analyses were conducted using a two-factor mixed analysis of variance (ANOVA) to assess the effects of “time” and “training group” on these outcomes. Percent changes were comparable between groups for most variables, with significant improvements observed in the LL-HV group for MV at 80% of 1RM and arm circumference. These findings suggest that LL-HV, emphasizing high-repetition sets, offers an effective alternative to HL-LV protocols for enhancing performance and structural adaptations in powerlifters.

Background: Visual and oculomotor skills are essential components of athletic performance, particularly in sports that demand rapid visual processing and precise motor execution. This study aimed to provide a descriptive analysis of the visual and oculomotor abilities of federated university athletes and explore their relationship with self-perceived performance. Methods: A total of 52 federated university athletes (34 men and 18 women), aged 18 to 37 years, participated in this observational and descriptive study. Visual assessments were conducted using the digital COI-Sport Vision system, evaluating static and dynamic visual acuity, stereopsis, vergence, contrast sensitivity, visual memory, hand-eye coordination, anticipation time, peripheral awareness, and identification. Results: The findings revealed patterns in the visual and oculomotor skills of this cohort, particularly in parameters such as dynamic visual acuity, stereopsis, and hand-eye coordination, which are relevant to the demands of their sports. Athletes reporting a higher satisfaction with their performance exhibited faster response times in visual memory (p = 0.039) and anticipation tasks (p = 0.022). These results suggest a potential relationship between self-perceived performance and specific visual skills, although further research is needed to establish causal links. Conclusions: This study provides valuable insights into the visual and oculomotor abilities of federated university athletes, emphasizing the potential influence of self-perceived performance on visual skill execution. While the results do not allow for direct comparisons with other populations, they lay the groundwork for future research into sport-specific visual demands. Incorporating validated psychological assessments and exploring longitudinal designs could further enhance an understanding of the interplay between visual skills, motivation, and athletic performance.
