Rapid Change in the Direction of Hand Movement to Increase Hand Propulsion During Front Crawl Swimming
This study aims to investigate the difference in hand acceleration induced by rapid changes in hand movement directions and propulsion between fast and slow groups of swimmers during front crawl swimming. Twenty-two participants, consisting of 11 fast and 11 slow swimmers, performed front crawl swimming at their maximal effort. Hand acceleration and velocity and the angle of attack were measured using a motion capture system. The dynamic pressure approach was used to estimate hand propulsion. In the insweep phase, the fast group attained significantly higher hand acceleration than the slow group in the lateral and vertical...

Effect of stroke direction on plantar pressure in each foot during the forehand and backhand stroke among healthy adult tennis players of different performance levels
ConclusionRegarding an appropriate plantar pressure distribution, our results suggest that during training of especially recreational and intermediate players attention should be paid to the feet rather than to stroke direction.

Physical Demands of Tennis Across the Different Court Surfaces, Performance Levels and Sexes: A Systematic Review with Meta-analysis
ConclusionsThe findings from this study provide a comprehensive summary of the physical demands of tennis. These results may guide tennis-specific training programmes. We recommend more consistent measuring and reporting of data to enable future meta-analysts to pool meaningful data.Clinical Trial RegistrationThe protocol for this systematic review was registered a priori at the Open Science Framework (Registration DOIhttps://doi.org/10.17605/OSF.IO/MDWFY).

The Effects of a Wetsuit on Biomechanical, Physiological, and Perceptual Variables in Experienced Triathletes
CONCLUSION: Wetsuit use reduces TI and, thus, drag; increases propelling proficiency; and shows lower fatigability, without modifying motor coordination, compared with swimsuit use at the same speed. The use of a wetsuit during training sessions is recommended to increase comfort and the positive effects on performance.PMID:36626910 | DOI:10.1123/ijspp.2022-0029

Does higher knee hyperextension in patients with hemiplegia affect lateral and medial meniscus volume in the paretic leg? A cross-sectional study
ConclusionsThe knee hyperextension could not be ignored by physicians and needed to be diagnosed and treated as early as possible, the time since hemiplegia could be an indicator of sign of knee hyperextension.

Is he or she the main player in table tennis mixed doubles?
ConclusionThis study considers several competition contexts to analyse the performance of male and female players in table tennis mixed doubles. We propose that the stroke performance of male versus female players is the most important factor affecting the results of mixed doubles matches. In addition, selecting the first server or first receiver in each game reasonably and analysing the stroke orders emphatically are also very important in mixed doubles.

Middle-distance Front Crawl Determinants When Using a
Wetsuit
Int J Sports Med DOI: 10.1055/a-1971-9008Our aim was to establish the determinants explaining the wetsuit advantages in
middle-distance swimming efforts. Thirty-one triathletes and open water swimmers
performed two 400 m front crawl bouts in a 25 m swimming pool
with swim and wetsuits (with 48 h rest in-between). Anthropometric,
kinematic and physiological variables were measured and Pearson correlation
coefficients and stepwise linear regression analysis were used to determine
their relationships. Associations observed in the 400 m front crawl
included time improved using wetsuit...

Biomarkers for warfighter safety and performance in hot and cold environments
Exposure to extreme environmental heat or cold during military activities can impose severe thermal strain, leading to impairment in task performance and increasing the risk of exertional heat (including heat stroke) and cold injuries that can be life-threatening. Substantial individual variability in physiological tolerance to thermal stress necessitates an individualized approach to mitigate the deleterious effects of thermal stress, such as physiological monitoring of individual thermal strain.

IOC consensus statement on recommendations and regulations for sport events in the heat
This document presents the recommendations developed by the IOC Medical and Scientific Commission and several international federations (IF) on the protection of athletes competing in the heat. It is based on a working group, meetings, field experience and a Delphi process. The first section presents recommendations for event organisers to monitor environmental conditions before and during an event; to provide sufficient ice, shading and cooling; and to work with the IF to remove regulatory and logistical limitations. The second section summarises recommendations that are directly associated with athletes’ behaviours...

Effects of paddle dimensions on shoulder joint torque for a swimmer with unilateral transradial deficiency
The objectives of this study were (i) to propose a new index which was the ratios of increased effort at shoulder joints when attaching paddles for the intact and deficient limbs, (ii) to investigate the effects of the paddle dimensions on the index by simulation, and (iii) to design and fabricate an actual paddle based on the determined dimensions. The actual paddle was tested by a participant to confirm its validity. From the parameter study, it was found that the index increased according to the increase in paddle size as well as the length of the forearm section of the paddle. It was also found that the index became cl...
