Background: whole body vibration (WBV) training appears to be an efficient alternative for conventional resistance training in older individuals. So far, no data exist about the vibratory effect on cardiorespiratory fitness.
Objectives: this randomised controlled trial assessed the effects of 1-year WBV training on cardiorespiratory fitness and muscle strength in community-dwelling adults over the age of 60.
Methods: a total of 220 adults (mean age 67.1 years) were randomly assigned to a WBV group, fitness group or control group. The WBV group exercised on a vibration platform, and the fitness group performed cardiovascular, resistance, balance and stretching exercises. The control group did not participate in any training. Heart rate was measured during a single WBV session. Peak oxygen uptake (VO(2peak)) and time-to-peak exercise (TPE) were measured during progressive bicycle ergometry. Muscle strength was assessed by a dynamometer.
Results: heart rate increased significantly during WBV training. After 1 year, VO(2peak), TPE and muscle strength increased significantly in the WBV and fitness groups. Both training groups improved similarly in VO(2peak) and muscle strength. The fitness group improved significantly more in TPE than the WBV group.
Conclusion: WBV training in community-dwelling elderly appears to be efficient to improve cardiorespiratory fitness and muscle strength.

Background: In osteoarthritis quadriceps strength is an important outcome to assess exercise capacity and recovery after arthroplasty. However, its measurement is limited due to lack of time and the need for trained personnel and equipment whose accuracy is verified.
Objectives: To find out the determinants of a reduced quadriceps strength and to establish a score to screen for it.

Purpose: Poland syndrome is a congenital malformation characterized by agenesis or hypoplasia of pectoralis muscles. There is a limited literature on how the anatomic anomalies of PS may impact the movement of the shoulder. This study analyzes the effects of absence of the pectoralis muscles on the shoulder kinematic.

Unlabelled: This study examines how power training affects estimated bone strength, revealing that females benefit more than males, especially in the upper limbs (radius). These findings highlight the importance of designing sex-specific exercise programs to enhance bone health. Further research is needed to optimize training duration and address site-specific differences.

Objective: The aim of the study was to analyze the effects of 16 weeks of Jazz Dance training compared to a control group in postmenopausal women, postintervention, and at the 6- and 12-month follow-ups, on cardiorespiratory fitness, body composition, muscle strength, and sleep quality.
Methods: Two-arm randomized clinical trial with a total of 47 women (jazz dance intervention group [JDIG] [n = 23] and control group (CG) [n = 24]) with a mean age of 53.41 ± 2.

Shoulder and elbow injuries are prevalent among baseball players, particularly pitchers, who experience repetitive eccentric loading of the shoulder, leading to muscle damage and increased injury risk. Nearly 40% of shoulder injuries in baseball occur in pitchers, with many facing low rates of return to sport. The rotator cuff (RC) muscles-supraspinatus (SSP), infraspinatus (ISP), subscapularis (SSC), and teres minor (TMin)-are crucial for shoulder stability, movement, and force generation, particularly in overhead sports.
