Aim: The Nordic hamstring curl appears effective in reducing the incidence of injury in physically active young adults, likely through its capacity as an eccentric exercise to increase muscle stiffness. Although eccentric exercises have been shown to increase muscle stiffness, medium- and long-term Nordic hamstring curl training programs have not demonstrated an effect on muscle stiffness. This study examined the acute effects of a single session of Nordic hamstring curls on the stiffness of the biceps femoris, semitendinosus, and semimembranosus muscles using ultrasound shear wave elastography, an accepted method for measuring passive muscle stiffness.

Background: The emergence of telesurgery has received global interest, with secure network transmission identified as a crucial determinant of its success. This study aimed to evaluate the safety and viability of employing quantum cryptography communication in remote partial nephrectomy.
Methods: The surgeon operated on the patient from a distance of over 260 km using remote control of a surgical robot.

This study examined the acute effects of dynamic stretching at different velocities on the neuromuscular system. Fourteen participants underwent four experimental sessions in random order: (1) control (lying at rest with the ankle in a neutral position); (2) slow velocity dynamic stretching (50 beats/min; SLOW); (3) moderate velocity dynamic stretching (70 beats/min; MOD); and (4) fast velocity dynamic stretching (90 beats/min; FAST). The stretching protocols consisted of four sets of 10 repetitions and targeted the plantar flexor muscles of the right ankle.

Background: The foam roller is considered a versatile tool. Along with an active warm-up, it appears to positively affect range of motion, stability, muscle stiffness, and perceived exertion with no reductions in performance.
Hypothesis/purpose: The main purpose of the study was to observe the effects of the utilization of a foam roller during the warm-up on ankle mobility and lower limb stability, and secondarily, to assess if any induced effects were sustained over time.

Introduction: Considering the theory of self-determination and its relationship with human motivation and the play-based approach (PBA), a training program is implemented in young middle and long-distance running athletes with play activities (simple tasks with rules in a ludic mood). The objectives were (1) to analyze the effects of a PBA on the autonomy support interpersonal teaching style (ASITS) perceived by athletes, the psychological variables of satisfaction of basic psychological needs, motivation, enjoyment and intention to continue practicing athletics and depending on sex, and (2) know the athletes' perception of this methodology after the intervention.
Method: Quasi- experimental design with a sample of 50 athletes (27 women and 23 men) with 17.
