Behavior of female judo weight divisions on approach and grip phases in different judo rules: The top 20 athletes from the 2016 and 2020 Olympic cycles.

In judo combat, the approach and gripping phases play a crucial role in determining victory, and it is believed that they can be influenced by the current rules. The objective of this study was to compare the technical-tactical actions executed by female judokas in the approach and gripping subphases during international competitions held in the 2016 and 2020 Olympic cycles, which featured different rules. We analyzed 1332 combat videos from the top 20 female judo athletes in the world rankings.

Physically active men with high brown adipose tissue activity showed increased energy expenditure after caffeine supplementation.

This study measured the effect of caffeine on brown adipose tissue (BAT) activity and the energy expenditure (EE) of subjects with high (HBAT) or low (LBAT) activation. We performed a quasi-experimental double-blind protocol in which 24 physically active healthy men were measured (age: 24.1 ± 6.

10 Years on Time-Motion and Motor Actions of Paired Mixed Martial Arts Athletes.

This study verified the performance probabilities by mixed martial arts rounds by the same athletes, doing paired comparisons of time-motion and actions before and after 10 y. The sample was composed of 845 Ultimate Fighting Championship rounds of 45 athletes separated into before (M1, age range 34-44 y) and after (M2, age range 44-54 y). Motor-control (takedowns, submissions, chokes, locks, strike actions to the head, and body and leg strikes attempted and landed) and time-motion (high and low intensities and standing and ground times) analyses were done.

Reproducibility (Reliability and Agreement) of Post-exercise Hypotension.

This study determined the reproducibility of post-exercise hypotension (PEH) calculated by the following methods: PEH_I=post-exercise BP - pre-exercise BP; PEH_II=post-exercise BP - post-control BP; and PEH_III=[(post-exercise BP - pre-exercise BP)-(post-control BP - pre-control BP)]. Twenty-five participants underwent four sessions divided in two blocks (test and retest). Each block consisted of one exercise and one control session.

Captopril does not Potentiate Post-Exercise Hypotension: A Randomized Crossover Study.

To evaluate whether captopril (3×50 mg/day) potentiates post-resistance exercise hypotension (PREH) in hypertensives (HT), 12 HT men received captopril and placebo for 4 weeks each in a double-blinded, randomized-crossover design. On each therapy, subjects underwent 2 sessions: Control (C - rest) and Resistance Exercise (RE - 7 exercises, 3 sets to moderate fatigue, 50% of 1 RM -repetition maximum). Measurements were taken before and after 30-60 min (Post1) and 7 h (Post2), and ambulatory blood pressure (BP) was monitored for 24 h.

Effects of resistance training on blood pressure in the elderly.

The aging process drastically reduces muscle mass, strength and power, decreasing the capacity to perform the activities of daily living. The practice of resistance exercises can reverse this picture, helping to maintain the muscular mass and improving muscular strength and resistance. However, the aging process causes cardiovascular alterations, which can result in increased blood pressure levels at rest and it is important to analyze the effects of resistance exercises on the blood pressure of elderly individuals.

Acute and chronic effects of aerobic and resistance exercise on ambulatory blood pressure.

Hypertension is a ubiquitous and serious disease. Regular exercise has been recommended as a strategy for the prevention and treatment of hypertension because of its effects in reducing clinical blood pressure; however, ambulatory blood pressure is a better predictor of target-organ damage than clinical blood pressure, and therefore studying the effects of exercise on ambulatory blood pressure is important as well. Moreover, different kinds of exercise might produce distinct effects that might differ between normotensive and hypertensive subjects.
