To run or not to run? Differences in implicit attitudes towards running: An EEG study.

02 10 2023

DOI: 10.1016/j.bbr.2023.114637 PMID: 37647993

To understand the reasons for individuals do or do not exercise, we examined differences in implicit (affective and instrumental) attitudes between runners and non-runners.... In conjunction with electroencephalography (EEG) technology, 31 participants completed the affective and instrumental implicit associations test (IAT).... Behavioural results showed that runners had more positive implicit (affective and instrumental) attitudes than non-runners. EEG results further explained the underlying mechanisms for the differences,... Higher levels of neural processing efficiency were required for runners to perceive affective expectations towards running. Furthermore, ERP indicators (N1 amplitudes of incompatible tasks) can be use...

Muscle synergies during the walk-run and run-walk transitions.

2024

Studies in walking-running transitions described... Twenty-four trained men participated in this study. A variable speed protocol on a treadmill was developed to record the activity of 14 muscle during walking, running and relative transitions. The pro... We described four different transition strides, two for increasing speed transitions, and two for decreasing speed transitions. Four to six synergy modules were found in each condition. According to t... Transition occurred at step level, and transition strides were composed by walk-like and run-like steps. Compared with previous studies in running and walking, both transitions needed earlier activati...

The Nike Vaporfly line of running shoes improves running economy by ∼2.7% to 4.2% at running speeds of 13 to 18 km·h-1. It is unclear whether similar benefits are conferred at slower speeds. Our purpo... Sixteen runners completed 4 × 5-minute trials at both 10 and 12 km·h-1 on the same day. Each shoe was tested twice at each speed in a counterbalanced, mirrored sequence. Data are displayed as mean (SD... A 2-way repeated-measures analysis of variance showed a significant shoe × speed interaction for oxygen consumption (P = .021).
