The objective of this study was to confirm whether gymnastics practice from a young age can induce greater vertical jump reliability. Fifty young female gymnasts (8.84 ± 0.62 years) and 42 females in the control group (8.58 ± 0.92 years) performed the following jump tests on a contact mat: squat jump, countermovement jump, countermovement jump with arm swing and drop jump from heights of 40 and 60 cm. The two testing sessions had three trials each and were separated by one week. A 2 (groups) × 2 (sessions) × 3 (trials) repeated measures analysis of variance (ANOVA) and a test-retest correlation analysis were used to study the reliability. There was no systematic source of error in either group for non-plyometric jumps such as squat jump, countermovement jump, and countermovement jump with arm swing. A significant group per trial interaction revealed a learning effect in gymnasts' drop jumps from 40 cm height. Additionally, the test-retest correlation analysis and the higher minimum detectable error suggest that the quick drop jump technique was not fully consolidated in either group. At an introductory level of gymnastics and between the ages of 8-10 years, the condition of being a gymnast did not lead to conclusively higher reliability, aside from better overall vertical jump performance.

Purpose: Competitive cheerleading (cheersport) is a physically demanding sport; however, there is a lack of information regarding its acute physiological responses during training or competition in these athletes. Thus, this study aimed to investigate these responses during both training sessions and simulated cheerleading competition routines (full-outs) among elite cheersport athletes.
Methods: Six Coed and 10 All Girl elite cheerleaders were included in this study.

The objective of the present study was to examine the impact of different plyometric training (PT) surfaces on the adaptive changes of jumping ability, sprinting speed, change of direction ability and strength performance in volleyball players. Forty male players participated in the study and were divided into four equal groups performing PT in aquatic (APT), sand (SPT), and land (LPT) surfaces, or an active control group (CON). All training groups indicated small to large significant (p = 0.

The countermovement jump (CMJ) is a widely used test to assess lower body neuromuscular performance. This study aims to analyze the validity and reliability of an iOS application using artificial intelligence to measure CMJ height, force, velocity, and power in unloaded and loaded conditions. Twelve physically active participants performed 12 CMJs with external loads ranging from 0% to 70% of their body mass while being simultaneously monitored with a pair of force platforms and the My Jump Lab application.

Vertical jump height from a countermovement jump is a widespread metric to assess the lower limb functionality. Motion capture systems and force platforms are considered gold standards to estimate vertical jump height; however, their use in ecological settings is limited. This study aimed to evaluate the feasibility of low-sampling-rate inertial measurement units as an alternative to the gold standard systems.

Background: Consuming collagen hydrolysate (CH) may improve symptoms of exercise-induced muscle damage (EIMD); however, its acute effects have not been compared to dairy protein (DP), the most commonly consumed form of protein supplement. Therefore, this study compared the effects of CH and DP on recovery from EIMD.
Methods: Thirty-three males consumed either CH ( = 11) or DP ( = 11), containing 25 g of protein, or an isoenergetic placebo ( = 11) immediately post-exercise and once daily for three days.
