Strength and Power Qualities Are Highly Associated With Punching Impact in Elite Amateur Boxers
TLDR
This study investigated the relationship between punching impact and selected strength and power variables in 15 amateur boxers from the Brazilian National Team and provides important information for coaches to specifically design better training strategies to improve punching impact.
Intersession and Intrasession Reliability and Validity of the My Jump App for Measuring Different Jump Actions in Trained Male and Female Athletes
TLDR
The iPhone app named My Jump provides reliable intersession and intrasession data, as well as valid measurements for maximal jump height during fast and slow stretch-shortening cycle muscle actions, and during concentric-only explosive muscle actions in both male and female athletes in comparison with a professional contact platform.
Differences in Muscle Mechanical Properties Between Elite Power and Endurance Athletes: A Comparative Study
TLDR
The power group presented better performance in vertical jumps, supporting the validity of these tests to distinguish between endurance and power athletes, and TMG can discriminate the "athlete-type" using noninvasive indices moderately correlated with explosive lower-body performance.
Effect of Match Importance on Salivary Cortisol and Immunoglobulin A Responses in Elite Young Volleyball Players
TLDR
Monitoring session-RPE, sC, and SIgA responses, in conjunction, during training and competition, would provide valuable informations regarding how athletes cope with sports induced stress.
Predicting MAOD using only a supramaximal exhaustive test.
TLDR
Data indicate that the MAOD(ALT) can be used to estimate the maximal accumulated oxygen deficit (MAOD), which was determined by calculating the difference between predicted O( 2) demand and accumulated O(2) uptake during the supramaximal test.
Physical and Physiological Demands of Field and Assistant Soccer Referees During America's Cup
TLDR
Top-class American FR and AR exhibited similar physical demands as previously reported by their European counterparts during international tournaments, and a new index of performance efficiency (Effindex) may provide an important tool for the evaluation of referees' and players' performance that requires further investigation.
Physiological responses to shuttle repeated-sprint running.
TLDR
The present results suggest that the ability to repeat sprints can be considered as a general quality and suggest that repeated shuttle sprints might be an effective training practice for eliciting a greater systemic physiological load, but perhaps not a greater loading of the vastus lateralis.
Sensitivity of physiological and psychological markers to training load intensification in volleyball players.
TLDR
The results suggest that performance in the CMJ is not a sensitive variable to the fatigue caused by intensification of training loads during a pre-competitive period in volleyball, whereas CK, TQR and RESTQ-Sport were shown to be sensitive measures.
Repeated Acceleration Ability (RAA): A New Concept with Reference to Top-Level Field and Assistant Soccer Referees
TLDR
The results of the present study would appear to support the appropriateness of a repeated acceleration ability (RAA) concept, instead of the repeated sprint ability(RSA) concept) in soccer referees.
The role of aerobic fitness on session rating of perceived exertion in futsal players.
TLDR
The VO2max plays a key role in determining the magnitude of an individual's perceived exertion during futsal training sessions, as measured by the session rating of perceived exertedion (session-RPE) method.
