Methods: To accomplish this, 15 male elite PP athletes participated in the study (age: 27.

Design: A cross-sectional study with a control group.

Setting: Center of Adapted Sports Training and Special Physical Education.

Can Post-Exercise Hemodynamic Response Be Influenced by Different Recovery Methods in Paraplegic Sportsmen?

Post-exercise hypotension is of great clinical relevance and also in sports training settings, as recovery speed is important. The aim of this study was to compare the influence of different recovery methods on post-exercise hemodynamic response. Twelve male paraplegic sportsmen (25.

Handgrip Strength Cutoff Points for Functional Independence and Wheelchair Ability in Men With Spinal Cord Injury.

Objectives: To determine optimal handgrip strength (HGS) cutoff points for greater functional independence and wheelchair skills in men with spinal cord injury (SCI), and to establish predictive equations for functional independence and wheelchair ability in men with SCI, based on demographic characteristics, HGS, and functionality.

Methods: In this cross-sectional study conducted at a rehabilitation hospital, 54 men with SCI were recruited and stratified into high and low paraplegia groups. All participants performed a maximum HGS test to determine cutoff points for the Spinal Cord Independence Measure (SCIM-III) and Adapted Manual Wheelchair Circuit (AMWC).

Peak Torque Prediction Using Handgrip and Strength Predictors in Men and Women With Motor Complete Spinal Cord Injury.

Objectives: To establish predictive equations for peak torque of muscle groups with totally and partially preserved innervation in individuals with motor complete spinal cord injury (SCI), based on hand dynamometry and strength predictor variables.

Methods: The cross-sectional study conducted at a rehabilitation hospital consecutively recruited 108 men and women with SCI. All participants performed maximum peak torque tests for shoulder abduction/adduction (isokinetic), trunk flexion/extension (isometric), and handgrip strength testing (hand dynamometer) to establish predictive peak torque equations.

Validation of the Repetitions in Reserve Rating Scale in Paralympic Powerlifting Athletes.

The present study aimed to validate the perceived exertion scale based on the repetitions in reserve (RIR) of Paralympic Powerlifting (PP) athletes. Twenty-one PP athletes were assessed in the one-maximum repetition test (1RM) of the bench press exercise, maximum repetition strength tests with loads corresponding to 90, 85, 80, and 75% of 1RM, and 4-repetitions strength tests (4-repST) with 100, 90, 85, 80, and 75% of the 1RM. The RIR scale was assessed after each set of the 4-repST and compared to the 1RM and maximum strength tests.

Evaluation of Strength and Muscle Activation Indicators in Sticking Point Region of National-Level Paralympic Powerlifting Athletes.

Background: The sticking region is considered an intervening factor in the performance of the bench press with high loads.

Objective: To evaluate the strength indicators in the sticking point region in Powerlifting Paralympic athletes.

Methods: Twelve Brazilian Powerlifting Paralympic athletes performed maximum isometric force (MIF), rate of force development (RFD), time at MIF, velocity, dynamic time in sticking, and surface electromyography in several distances from the bar to the chest.

The Torque Referenced to a Perceived Exertion Level Is Affected by the Type of Movement in Men With Spinal Cord Injury.

Objectives: To compare a standardized submaximal intensity (based on the rate of perceived exertion [RPE]) with the percentage of the average and peak torque during a familiarization session in individuals with different spinal cord injury (SCI) levels in gravity-resisted and gravity-assisted movements.

Methods: This was a cross-sectional study at a rehabilitation hospital. Thirty-six individuals stratified in tetraplegia (TP), high paraplegia (HP), and low paraplegia (LP) groups and 12 matched control participants (CG) were enrolled in the study.

Synchronous and asynchronous tele-exercise during the coronavirus disease 2019 pandemic: Comparisons of implementation and training load in individuals with spinal cord injury.

Introduction: Tele-exercise could represent an alternative for remote care in individuals with spinal cord injury at this time of the pandemic of coronavirus disease 2019. However, the differences regarding the training loads and implementation between synchronous and asynchronous types are not yet known. The purpose of this study was to compare the implementation and training load between synchronous and asynchronous tele-exercise programs in individuals with spinal cord injury.

Does prolonged walking cause greater muscle fatigability in individuals with incomplete spinal cord injury compared with matched-controls?

Background: Individuals with incomplete spinal cord injury (iSCI) might show muscle fatigability during walking, primarily over long distances. The cause can be related to the motor impairment and walking compensations identified in this population. However, evidence on the occurrence of muscle fatigability after prolonged walking in individuals with iSCI is conflicting.

Kinesiotaping enhances the rate of force development but not the neuromuscular efficiency of physically active young men.

Objective: To evaluate the NME and RFD of the soleus and gastrocnemius muscles in physically active individuals under KT application.

The interactions between hemostasis and resistance training: a review.

Physical inactivity is considered a risk factor for cardiovascular disease and is strongly associated with changes in arterial structure. Regular physical activity and exercise contributes to the prevention of coronary artery disease. Therefore, cardiovascular and resistance training improve hemostatic parameters and promote a less thrombotic blood profile.
