Soft Robotic Engines with Non‐Reciprocal Motion by Physical Intelligence

Advanced Materials, Volume 37, Issue 45, November 13, 2025.
Movement is vital, and it requires breaking symmetry. This study introduces a hydrogel engine that achieves non‐reciprocal motion through kinetic asymmetry in repeated actuation cycles. This approach for breaststroke‐swimming‐like motion is embedded inside the material and establishes a new paradigm of physical intelligence for soft robotics.

Wave Characteristics in Breaststroke Technique with and Without Snorkel Use [PDF]

Journal of Human Kinetics, 2013
Abstract The purpose of this paper was to examine the characteristics of waves generated when swimming with and without the use of Aquatrainer® snorkels. Eight male swimmers performed two maximal bouts of 25 m breaststroke, first without the use of a snorkel (normal condition) and then using a snorkel (snorkel condition).

The Water Polo Intermittent Shuttle Test in Women's Water Polo Players

European Journal of Sport Science, Volume 25, Issue 11, November 2025.
ABSTRACT This study aimed to (a) establish the test‐retest reliability of the water polo intermittent shuttle test (WIST) in elite female water polo players, (b) investigate the validity of the WIST to determine positional differences in WIST scores within this population and (c) distinguish between competitive female playing standards.

Acute metabolite responses to swimming exercise of different intensities in highly trained male and female swimmers

Physiological Reports, Volume 13, Issue 16, August 2025.
Abstract We investigated metabolite responses to different swimming intensities in 16 highly trained swimmers (9 males, 7 females, aged 16–24 years). After determining critical swimming speed (CS) with a 12 × 25 m maximal effort test, participants completed three swimming trials at moderate (below CS), heavy (at CS), and severe (above CS) intensities ...

Using acousmatic storytelling to facilitate communication and social interactions in people living with dementia: An iterative exploratory 12‐week study

Australasian Journal on Ageing, Volume 44, Issue 2, June 2025.
Abstract Objective Communication challenges in people living with dementia can limit social interactions with fellow residents and hinder professional carers' ability to provide person‐centred care. While research highlights the benefits of reminiscence, storytelling and music interventions in facilitating social interaction, the potential of using ...

A Catalog of “Knee Friendly” Aerobic Exercises Developed for Patients With Knee Osteoarthritis: An International Patient Survey

ACR Open Rheumatology, Volume 7, Issue 5, May 2025.
Objective Aerobic exercise is recommended for the management of knee osteoarthritis (OA), but knee pain is often a barrier for participation. Some types of aerobic exercise may be less painful to undertake than others, though little is known about which are the most “knee friendly,” that is, unlikely to exacerbate knee pain to an unacceptable level ...

A Multidisciplinary Comparison of Different Techniques Among Skilled Water Treaders

Frontiers in Physiology, 2021
In an immersion incident, a person may be required to tread water for extended periods of time in order to survive. Treading water, or maintaining a stable head position above the water surface, can be achieved in several different ways.
