In this study, we aimed to determine the effects of varying loads during shoulder external rotation exercises on exerted torque and muscle activity of the infraspinatus, teres minor, and deltoid. Twenty-four upper limbs from 12 healthy adult males (22.5 ± 1.9 years) were included. Participants performed shoulder external rotation exercises with low-, medium-, and high-load conditions using elastic bands of three different tensions. The number of exercises was set so that the total workload during the exercise was equal for each loading condition. The torque of the shoulder external rotation and electromyography (EMG) amplitude of the infraspinatus, teres minor, and the posterior deltoid were measured during the concentric shoulder external rotation task, before and after the exercise. In addition, the muscle activity ratio of the three muscles was calculated. Analysis divided into 30° intervals, under the low-load condition, shoulder external rotation torque and EMG amplitude of the infraspinatus and teres minor did not change; However, the EMG amplitude of the posterior deltoid increased significantly. The muscle activity ratio in the posterior deltoid showed exercise range × time interaction, with a significant increase from pre-exercise (Pre) (13.59 ± 5.70%) to 20 min after the exercise (15.40 ± 6.03%) in the 61°-90° external rotation range. In the medium- and high-load conditions, the EMG amplitude significantly increased for all muscles. However, under the medium-load condition, significant differences were observed between 0-30° (Pre: 25.4 Nm, 20 min: 26.0 Nm), 31-60° (Pre: 24.3 Nm, 20 min: 25.4 Nm), and 61-90° (Pre: 23.7 Nm, 20 min: 24.6 Nm). There was also an increase in the muscle activity ratio in the posterior deltoid, with a main effect on time in the medium load condition (<i>p</i> < 0.05).

Therefore, the present comparative case study aims to apply the new regulation on backstroke finish, examining the swimming efficiency and underwater kinematics of an elite Olympic-level swimmer, and comparing the data with the published ones from a previous study on regional-level swimmers. A 19-year-old male Olympic-level backstroke swimmer performed three all-out 20 m backstroke swims: (i) touching the wall, breaking the water's surface with one part of their body (Classic), (ii) touching the wall with one hand, submerging the body two strokes after passing the last 5 m (Dive-One Hand) and (iii) touching the wall on streamline position, submerging the body two strokes after passing the last 5 m (Dive-Streamline) Kinematic analysis of the intermediate 10 m and the last 5 m was conducted using a digital video camera. Descriptive statistics and the Crawford-Howell <i>t</i>-test were utilized for the comparisons between elite and regional-level swimmers.

In Serbia, however, the absence of national accrediting bodies for standardised qualifications has led to a lack of formal recognition of exercise professionals. The views of personal training clients regarding their training practices and experiences have been explored previously. Building on this, the current study investigated the perspectives of high-level Serbian PTs, examining their professional developmental journeys, educational background, coaching philosophies, professional needs and experiences. The aim was to provide insights for educational institutions and other practitioners to adopt successful approaches that inspire lifelong exercise and promote positive lifestyle changes for increasingly sedentary populations. Using a snowball sampling method, we interviewed 12 high-level PTs, selected for their exceptional practice as recognised by their peers. The findings suggest a need for a shift from traditional, physical performance-focused approaches toward a more holistic model that incorporates psychosocial support and a care for the whole person, fostering an appreciation for the concept of physical literacy. Additionally, the study identifies critical gaps in PTs education and training, particularly concerning the lack of focus on behavior change models and inquiry-based skills essential for their future self-directed learning. These areas were highlighted as vital for continued professional development after formal qualifications are obtained. In conclusion, this research underlines the need for holistic training approaches to improve clients' physical and health outcomes. The study offers guidance to shape industry standards, foster accreditation systems, and start the debate on how best to continually support PTs during their careers.

The demanding sprint format, with most of the race time spent on uphill sections, highlights the importance of body composition and maximal oxygen consumption (V˙O<sub>2max</sub>). While previous studies have primarily focused on male athletes, this study aimed to analyze sex differences in physiological parameters of elite SkiMo athletes, hypothesizing that differences in vertical velocities (vV) would surpass those in V˙O<sub>2</sub> at ventilatory thresholds (VT<sub>1</sub>, VT<sub>2</sub>) and maximal intensity (MAX), respectively. Twenty elite/worldclass Swiss SkiMo athletes (6 women, 14 men, aged 20-32 years) participated in the study. They performed a graded exercise test to exhaustion on a treadmill set at a 25% slope, with breath-by-breath gas exchanges.
