: This study examined the influence of competition level and player position on shooting accuracy and kinematic parameters in U18 male basketball players, focusing on two-point jump shots and free throws. : Thirty-eight higher-level (HL-group) and forty-one lower-level (LL-group) participants, categorized into guard, forward, and center subgroups, completed a two-point basketball shooting test, followed by a free-throw shooting test after a 30 min interval. These tests were administered using a crossover, counterbalanced approach with the Latin square method to ensure effective randomization.

Impact of glossopharyngeal insufflation and complete exhalation on breath-hold performance and physiological parameters in elite skin divers.

Purpose: This study examined the physiological responses of ten elite divers to normal breathing (BHn), glossopharyngeal inhalation (BHi), and complete exhalation (BHe) prior to five maximal breath-hold (BH) efforts.

Methods: Breath-hold time (BHT), hemological variables, mean arterial pressure (MAP), other hemodynamic indices, and diaphragmatic activity (DA) were recorded. During BHs, phases were identified as easy-going (EPh: minimal DA), struggling (SPh: increased DA), PhI (MAP transition), PhII (MAP stabilization), and PhIII (steep MAP increase).

Basketball Fatigue Impact on Kinematic Parameters and 3-Point Shooting Accuracy: Insights across Players' Positions and Cardiorespiratory Fitness Associations of High-Level Players.

This study investigated the impact of basketball-induced fatigue on 3-point jump shooting accuracy, the ball's entry angle (EA) into the hoop, shot release time (RT), their relationship with player positions in high-level basketball, and the correlation between cardiorespiratory fitness markers and potential shooting performance changes. Guards (n = 13), forwards (n = 13), and centers (n = 12) underwent physiological assessments. Sequentially, they performed 15 jump shots (PRE), a basketball exercise simulation (BEST) involving 24 × 30 s circuit activities, and a repeated shooting test (POST).

Pre-exercise mangiferin-quercetin may enhance athletic performance. This study investigated the effect of mangiferin-quercetin supplementation on high-level male basketball players during a basketball exercise simulation test (BEST) comprising 24 circuits of 30 s activities with various movement distances. The participants were divided into two groups (EXP = 19 and CON = 19) and given a placebo one hour before the BEST (PRE-condition).

The Effect of a Balance Training Program on the Balance and Technical Skills of Adolescent Soccer Players.

Soccer is a complex sport, and balance appears to play a crucial role in the quality execution of technical skills, which are mostly performed while standing on one foot. Nevertheless, in younger ages, when learning still affects soccer performance, the effect of a balance-training program on the player's balance and technical skills remains unexplored. This research examined the effect of a balance-training program (BTP) on balance and technical skills of adolescent soccer players.

Analysis of a comprehensive dataset: Influence of vaccination profile, types, and severe acute respiratory syndrome coronavirus 2 re-infections on changes in sports-related physical activity one month after infection.

This dataset was created with the primary objective of elucidating the intricate relationship between the incidence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) re-infections and the pre-illness vaccination profile and types concerning alterations in sports-related physical activity (PA) after SARS-CoV-2 infection among adults. A secondary objective encompassed a comprehensive statistical analysis to explore the influence of three key factors-namely, Vaccination profile, Vaccination types, and Incidence of SARS-CoV-2 re-infections-on changes in PA related to exercise and sports, recorded at two distinct time points: one to two weeks prior to infection and one month after the last SARS-CoV-2 infection. The sample population ( 5829), drawn from Hellenic territory, adhered to self-inclusion and exclusion criteria.

Physiological responses during static apnoea efforts in elite and novice breath-hold divers before and after two weeks of dry apnoea training.

This study examined the effect of breath-hold (BH) training on apnoeic performance in novice BH divers (NBH:n = 10) and compared them with data from elite BH divers (EBH:n = 11). Both groups performed 5-maximal BHs (PRE). The NBH group repeated this protocol after two weeks of BH training (POST).

Time Course of Performance Indexes, Oxidative Stress, Inflammation, and Muscle Damage Markers after a Female Futsal Match.

Background: Our aims were to investigate the time-course effects of a futsal match on performance, oxidative stress, and muscle damage markers, as well as inflammatory and antioxidant responses during a 6-day post-match period.

Methods: Thirty-four female high-level futsal players were assessed on several oxidative stress, inflammation, subjective muscle soreness, subjective rate perceived exertion, and performance tests before a futsal match, immediately after, and 24 h to 144 h after.

Results: Counter movement jump, 20 m, and 10 m sprints performance significantly decreased immediately after the match ( < 0.

Pivot Step Jump: A New Test for Evaluating Jumping Ability in Young Basketball Players.

Jumping ability in basketball is usually assessed using standardized vertical jump tests. However, they lack specificity and do not consider the player’s basketball skills. Several studies have suggested performing specific jump tests, which are tailored to the movement patterns and requirements of a basketball game.

Effect of 3 vs. 3 Soccer Small-Sided Game on Various Performance, Inflammatory, Muscle Damage and Hormonal Indicators in Semi-Professional Players.

The purpose of this study was to examine the effect of a soccer small-sided game (SSG) on performance, inflammatory, muscle damage and hormonal indicators. Twenty-two male soccer players participated and were assigned to either experimental (EXP = 12) or control (CON = 10) groups. Subjective fatigue (RPE) and lactate (La¯) were measured during the SSG; vertical squat jump (SJ), 20-m sprint, creatine kinase (CK), interleukin-6 (IL-6), cortisol (C), and testosterone (T) were measured before (PRE), after (POST), 24 h, 48 h, and 72 h after the SSG in the EXP group.

Meta-Analysis of Carbohydrate Solution Intake during Prolonged Exercise in Adults: From the Last 45+ Years' Perspective.

Carbohydrate (CHO) supplementation during prolonged exercise postpones fatigue. However, the optimum administration timing, dosage, type of CHO intake, and possible interaction of the ergogenic effect with athletes' cardiorespiratory fitness (CRF) are not clear. Ninety-six studies (from relevant databases based on predefined eligibility criteria) were selected for meta-analysis to investigate the acute effect of ≤20% CHO solutions on prolonged exercise performance.

PEA: Five maximum repeated apnea maneuvers prior to middle-distance racing.

It was hypothesized that executing repeated maximum apnea efforts would improve performance in a subsequent time to exhaustion test. Indeed, in young moderately fit male subjects without former experience in apnea has been shown that five repeated apnea maximal efforts with face immersion in cold water (PEA) have advantageous effect to consecutive performance in a time to exhaustion ride without being further affected by apnea training of two weeks. So, in the current article, we describe, in details, the protocol procedure and the technical steps of the five maximum-repeated apnea maneuvers prior to a middle-distance racing in order to improve performance, from our previous relevant published research.

Impact of lockdown on smoking and sleeping in the early COVID-19 presence: Datasets of Greek Adults sample.

The impact of lockdown on life style and behaviour have piqued the interest of people and scientific community, all over the world. It has been demonstrated that in some countries, mandatory stay-at-home limitations and self-isolation measures are linked to an increase in sleeping hours and smoking cigarettes per day. However, these results derive from countries that lockdown had different features and length, and it is possible that society, culture, customs, ecological or other factors may independently or in combination affect life style habits (such sleeping and smoking) in different populations.

Return to Basketball Play Following COVID-19 Lockdown.

Due to concerns regarding the spread of coronavirus (COVID-19), major sporting events and activities have been temporarily suspended or postponed, and a new radical sports protocol has emerged. For most sports there are few recommendations based on scientific evidence for returning to team-game activities following the lifting of COVID-19 restrictions, the extended duration of lockdown, and self-training or detraining in the COVID-19 environment, and this is especially true for basketball. A post-lockdown return to the basketball court ultimately depends on the teams-coaches, trainers, players, and medical staff.

Five repeated maximal efforts of apneas increase the time to exhaustion in subsequent high-intensity exercise.

Ten subjects were tested on a cycle ergometer to exhaustion with intensity corresponding to 150 % of their peak power output (TF150) under three conditions [C: base line measurement; PRE: after five repeated breath hold maneuvers (BH); and POST: after 5BH, preceded by two weeks of BH training]. Respiratory and blood measurements were carried out. Upon cessation of 5BH, subjects compared to C condition started TF150 with reduced arterialized blood pH (C:7.

The Role of CO on Respiration and Metabolism During Hypercapnic and Normocapnic Recovery From Exercise.

High intensity exercise can lead to depletion of CO from the body (hypocapnia). This disturbance becomes more noticeable during recovery or between seasons of intermittent exercise, putting the subject in a neural fatigue state. : A possible hypothesis to address this condition would be to provide high CO mixtures (hypercapnic) during the recovery period from exercise in order to relieve hypocapnia.

Repeated apneas and hypercapnic ventilatory response before and after apnea training.

Background: Habitual exposure to carbon dioxide (CO2) is expected, but it is not proven, to dull ventilatory sensitivity to co2 by reducing hypercapnic ventilatory response (HCVR) as it is expressed by the slope of the derived response curve (CO2 sensitivity: ΔVE/ΔPetCO2). It was hypothesized that HCVR is decreased by repeated breath hold maximal efforts (RBHE) before and after apnea training in comparison with no training and the control condition.

Methods: Two groups of breath holders, a control (CBH) group and novices to breath hold activities (NBH), visited the laboratory on four different occasions.
