The aim of this study is to investigate the effects of four weeks of land- and water-based inspiratory muscle training (IMT) on performance and selected physiological variables in young swimmers. A total of 30 competitive swimmers (22 males and 8 females), who have been training regularly for at least two years, will be voluntarily recruited and assigned to three groups: Land + IMT, Swimming + IMT, and Water + IMT. To compare the effects of different training protocols and evaluate their specific contributions to performance, participants will undergo assessments before the intervention and after the completion of the four-week training period. These assessments will include anthropometric measurements, pulmonary function tests, respiratory muscle strength, 100- and 200-meter freestyle swimming performance, stroke rate and stroke efficiency, as well as cardiopulmonary capacity. Previous studies investigating the effects of inspiratory muscle training in swimmers have generally applied the intervention in land-based settings and reported positive physical and physiological adaptations. However, to the best of our knowledge, no previous study has examined the effects of IMT performed in the water in swimmers. This novel approach is expected to better simulate the actual breathing demands encountered during swimming, thereby improving respiratory control, promoting a more efficient breathing rhythm during competition, and enhancing swimming performance.

This randomized controlled trial investigated the effects of a four-week inspiratory muscle training (IMT) program on physical and motor performance parameters and shooting accuracy in elite male air pistol athletes. Twenty athletes were randomly assigned to either an IMT group or a control group. Outcome measures included jumping performance, reaction time, flexibility, and shooting accuracy assessed via the SCATT system. The findings demonstrated that IMT significantly improved lower-limb explosive power and shooting performance without affecting reaction time or flexibility.

A total of 18 participants are planned to be included in the study. Participants will be randomly assigned into two groups in the order of their arrival. One group will perform strength exercises in addition to standard swim training (strength group), while the other group will perform plyometric exercises in addition to standard swim training (plyometric group). Both groups will participate in two training sessions per week for a duration of 8 weeks. The 50m sprint biomechanics, stroke frequency, or overall performance will be evaluated before and after the intervention.

Pre-workout supplements (PWS) consumption in recreationally or physically trained males lead to many performance-enhancing benefits, including improvements in mean power output during single and repeated sprints, agility, reaction times, lower body muscular endurance and reduced fatigue. PWS ingestion also improves anaerobic performance and prolongs time to exhaustion during high-intensity intermittent exercise. However, PWSs' effectiveness is not constant, as they do not alter anaerobic power, jumping performance or blood lactate concentrations after a training session, at least in recreationally trained males and strength-power athletes. Moreover, the effects of long-term PWS supplementation, where some nutritional agents were combined (e.g., β-alanine, creatine, citrulline malate, etc.) to assess endurance-trained runners or elite cyclists' performance, are mixed and less clear. Even though the popularity of PWS use has increased among trained/professional athletes, most of the data in this area are derived from recreationally and not from well-trained athletes of a competitive level (especially in team sports). Therefore, the present study aimed to examine the acute and chronic effects of a PWS, containing 200 mg caffeine, 3.3 g creatine monohydrate, 3.2 g βalanine, 6 g citrulline malate and 5 g BCAA per dose, on shooting, jumping, sprinting, agility, aerobic and anaerobic performance in well-trained basketball players.

Only very few studies have prospectively looked at the effect of repeated intensive plasma donation. In collaboration with the Rode Kruis Vlaanderen, we have recently found that repeated whole blood donation with a 3-month interval in between induced a drop in markers for iron status, which worsened with the number of donations. The repetition effect of the donations, whether whole blood or plasma, can be different from the effects measured after one single donation. It is therefore critical to test and document this repetitive effect to build trustable and valid guidelines concerning repetitive plasma donation.

Whereas beetroot juice (BJ) supplementation is shown to increase physical performance in endurance activities, its benefits in team sports has been barely studied. In this randomized placebo-controlled study, we investigated the effects of BJ acute supplementation in improving neuromuscular performance and physical match activity in basketball.
