Photobiomodulation on Performance in Female Futsal Athletes

The aim of this study is to investigate the effects of photobiomodulation therapy (PBMT) on physical performance in female futsal athletes. It is hypothesized that PBMT is superior to placebo condition in improving the ability to perform repeated sprints and aerobic capacity in high-intensity, intermittent activity (i.e., Bangsbo sprint test and yoyo intermittent recovery level-1, respectively).

Acute Effects of Patellar Tendon Ultrasound on Countermovement Jump Performance

This randomized, double-blind, controlled trial aims to investigate the acute effects of therapeutic ultrasound applied to the patellar tendon on vertical jump performance in healthy university students. Therapeutic ultrasound is widely used in physiotherapy to influence soft tissue properties through thermal and mechanical effects; however, its immediate impact on explosive lower-extremity performance and neuromuscular function remains unclear. Participants will be randomly assigned to either a therapeutic ultrasound group or a sham ultrasound (placebo) group. In the intervention group, therapeutic ultrasound will be applied to the patellar tendon using a frequency of 1 MHz and an intensity of 1.5 W/cm² in continuous mode for 5 minutes. In the control group, a sham ultrasound procedure will be performed using the same device and duration without delivering therapeutic energy. Both the participants and the outcome assessor will be blinded to group allocation. Vertical jump performance will be evaluated using the countermovement jump (CMJ) test recorded with the My Jump 2 smartphone application. In addition, quadriceps muscle strength will be measured using a hand-held dynamometer, and knee joint position sense will be assessed using a joint position reproduction test. All measurements will be conducted before and immediately after the intervention. This study will provide evidence regarding whether therapeutic ultrasound applied to the patellar tendon can acutely influence explosive performance, muscle strength, and proprioception in healthy individuals.

Effects of Weekly Set Volume on Muscle Adaptation

The progressive loss of strength and muscle mass is a natural aging process, with direct implications for functional capacity. Resistance training (RT) is considered the main intervention to counteract this decline. Although the RT guidelines are well established, the ideal weekly set volume to maximize strength and hypertrophy gains in older adults remains unknown. The purpose of this study is to investigate the effects of different volumes of weekly sets of RT on muscle strength and hypertrophy in older adults
