*ATHLETIC ability, *COLLEGE athletes, *STATISTICAL correlation, *JUMPING, *MUSCLE contraction, *MUSCLE strength, *STATISTICAL hypothesis testing, *STATISTICS, *T-test (Statistics), *EFFECT sizes (Statistics), *INTER-observer reliability, *DATA analysis software, *DESCRIPTIVE statistics
Abstract

The article cites a study which determined the relationship between isometric strength and performance during the squat jump (SJ) and countermovement jump (CMJ). The study results demonstrates that absolute isometric peak force (IPF) and IMP are related to vertical jump (VJ) peak force (PF) and peak power (PP), but not VJ height.

The article discusses research which was conducted to investigate and compare the internal and external training loads during basketball training. Researchers evaluated eight male semiprofessional players.They found that significant relationships were found between internal and external training and that internal training load models measured different constructs of the training process than the accelerometer training load model in basketball settings. They concluded that coaches should use both types of training.

Abstract

The article discusses research which was conducted to examine the relationship between lactate threshold (LT) as a percentage of maximal oxygen consumption (Vo2max) and power output of LT (LTw) and also to investigate to what extent Vo2max, oxygen cost of cycling (Cc), and maximal aerobic power (MAP) determine LTw in cycling. Researchers evaluated 108 male cyclists. After evaluating the cyclists, researchers found that they were able to develop a new time-saving method for calculating LTw in well-trained cyclists.

Abstract

The article presents a study of the effects of the medicinal herb Rhodiola rosea on endurance exercise performance, including perceived rate of exertion, mood, and cognition. Subjects performed a 6-mile time trial on a bicycle ergometer following acute dose of Rhodiola or placebo and were evaluated for blood lactate and salivary cortisol and alpha-amylase before and after exercise. The results indicate that R. rosea decreased heart rate and perceived exertion, which produced faster trial times.
