Patients achieved similar reductions in knee pain with single- and three-set resistance training.

Patients improved self-reported function to a similar extent with single- and three-set resistance training.

Both training approaches produced comparable gains in muscle strength and hop performance.

Single-set resistance training represents an effective and time-efficient intervention for the initial management of patellofemoral pain (PFP).

Supervised, moderate-intensity, multimodal training delivered over 16 weeks improves sleep in older adults.

Those who underwent training experienced an increase in sleep efficiency, achieved by reducing sleep latency, average awakenings, sleep fragmentation, and WASO.

Older adults showed high adherence to the training programme. Therefore, these findings provide valuable information for decision-making when choosing the most appropriate exercise modalities for older populations.

These findings could contribute to the recommendation of multimodal training as a strategy to improve sleep.

BacKS was successfully translated into Brazilian Portuguese (BacKS-BR).

The BacKS-BR has adequate content, construct, and structural validity.

Internal consistency and reliability were both acceptable (>0.70).

BacKS-BR showed acceptable cross-cultural measurement invariance.

BacKS-BR can be used to assess evidence-based understanding of low back pain.

The DPEBBS-BP presented adequate measurement properties.

Overall, participants scored benefits higher than barriers.

Younger and physically active individuals perceived greater benefits.

Barriers showed moderate correlations with DASI and the functional capacity domain (SF-36).

This is a valuable tool for Brazilian professionals to evaluate people on hemodialysis.
