Acute and time-course changes in hemodynamic and physical performance parameters following single and multiple resistance training sets in cognitively impaired individuals: A randomized crossover study.

This study analyzed the acute and time-course changes following one resistance training (RT) set (1SET) and three sets (3SET) on hemodynamic and physical performance parameters in individuals with different cognitive impairment levels. Thirty-nine individuals (22 women and 17 men aged 80 ± 9 years) grouped by cognitive impairment (mild [MILD], moderate [MOD], and severe [SEV]) randomly performed two protocols, each separated by one week, of 1SET or 3SET of 10 repetitions. Before (PRE), immediately (POST), and 72 h after (POST72) protocols, the participants performed the following measurements: systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), 1-kg medicine ball throw (MBT) distance, five-repetition sit-to-stand (STS) time, and handgrip strength (HGS).

Ten elite futsal players (24.8 ± 5.

Manipulating the Resistance Training Volume in Middle-Aged and Older Adults: A Systematic Review with Meta-Analysis of the Effects on Muscle Strength and Size, Muscle Quality, and Functional Capacity.

Background: Effective manipulation of the acute variables of resistance training is critical to optimizing muscle and functional adaptations in middle-aged and older adults. However, the ideal volume prescription (e.g.

Load-power relationship in older adults: The influence of maximal mean and peak power values and their associations with lower and upper-limb functional capacity.

Identifying the relative loads (%1RM) that maximize power output (P) in resistance exercises can help design interventions to optimize muscle power in older adults. Moreover, examining the maximal mean power (MP) and peak power (PP) values (Watts) would allow an understanding of their differences and associations with functionality markers in older adults. Therefore, this research aimed to 1) analyze the load-mean and peak power relationships in the leg press and chest press in older adults, 2) examine the differences between mean P (MP) and peak P (PP) within resistance exercises, 3) identify the differences between resistance exercises in MP and PP, and 4) explore the associations between MP and PP in the leg press and chest press with functional capacity indicators.

Validity and Reliability of The Smart Groin Trainer for Measuring Hip Adduction Strength.

We analyzed the Smart Groin Trainer device's validity and reliability to measure the isometric hip adduction strength during the adductor squeeze strength test. Fifteen professional soccer players (25.33±4.

Maximum Isometric and Dynamic Strength of Mixed Martial Arts Athletes According to Weight Class and Competitive Level.

Mixed martial arts (MMA) athletes must achieve high strength levels to face the physical demands of an MMA fight. This study compared MMA athletes' maximal isometric and dynamic strength according to the competitive level and weight class. Twenty-one male MMA athletes were divided into lightweight professional (LWP; = 9), lightweight elite (LWE; = 4), heavyweight professional (HWP; = 4), and heavyweight elite (HWE; = 4).

Development Technologies for the Monitoring of Six-Minute Walk Test: A Systematic Review.

In the pandemic time, the monitoring of the progression of some diseases is affected and rehabilitation is more complicated. Remote monitoring may help solve this problem using mobile devices that embed low-cost sensors, which can help measure different physical parameters. Many tests can be applied remotely, one of which is the six-minute walk test (6MWT).
