Changes in Selected Physiological Parameters Following a Training Block of Specific Circuit Training Among National Top-level Basketball Players

International Journal of Exercise Science 13(6): 1156-1166, 2020. The study aims at measuring the effects of six weeks of specific circuit training (SCT) according to the 15-15 modality, on selected physiological parameters in national top-level basketball players. It was an intervention study, undertaken with 44 senior players randomly assigned to two groups depending on the program: intervention (IG: n = 22; SCT) and control (CG: n = 22; usual content of the defending champion team\u27s), submitted to a six-week training block. The heart rate recovery at 1 (HRR1) and then 2 (HRR2) minutes, the double product (DP) and O2max were assessed prior to and at the end of the training period. As appropriate, the Student t-test on paired or independent samples, was used to compare measures and groups. At the end of the training period, the HRR1 decreased by 14.2% (p = 0.01) and 14.1% (p = 0.03) respectively in IG and CG. The mean HRR2 was higher in IG than in GC (63 ± 8 bpm versus 57 ± 6 bpm, p = 0.003) at the end of the training period. The variation of DP in IG was not significant (p = 0. 42) while it increased by 7.2% (p = 0.0005) in CG. The O2max increased by 6.5% (p ˂ 0. 001) in IG but not in CG (p = 0.50). The specific circuit training block in the 15-15 modality improved heart rate recovery at one minute and O2max, but had no effect on the double product in the basketball players studied

Wearing Judogi in a Humid Tropical Environment: Effect on Performance and Hydro-Electrolytic Parameters

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 8, 2022. Extremely high heat stress environmental conditions in sub-Saharan Africa influences sports performance. The aim of this study was to assess physical changes and physiological responses associated with wearing judogi during 8 weeks training session in a hot environment. In this quasi-experimental study, trained male judokas (20.06 ± 1.24 years old), were assessed before and after a training session, while either wearing a judogi (experimental group n = 12) or cotton tee shorts (control group n = 12). All athletes completed testing and were evaluated for anthropometric, physiological and urine parameters. A significant decrease in body mass (BM) (P.02) was observed in the experimental group but not the control group. In contrast, VO2max was significantly improved in the control group (p = 0.018). Special Judo Fitness Test indicators of athletes in the experimental group were lower than those in the control group (p\u3c0.01) after the 8 weeks training. In addition, significant decreases in sodium (Na+) (p = 0.005), potassium (K+) (p\u3c0.001) and chloride (Cl-) (p\u3c0.001) ion concentration were found in athletes in the experimental group. Body mass, fitness and hydroelectrolytic parameters decreased during those 24 training sessions in judogi wearing athletes. Wearing a judogi and training in open environments in a hot environment impairs judo performance

Changes in Renal Parameters during a Training Camp among Handball Players in the Sub-Saharan Environment

The aim of the study was to describe the changes in kidney parameters induced by 10 days of tapering (TP) during a training camp (TC), where the players were preparing for a group competition, in 15 female handball team members of a Division 1 Amateur of Benin, in the sub-Saharan environment. Measures were taken in all the players before and after the intensive training (IT) and tapering (TP) phases in an intervention study. The estimated glomerular filtration rate (eGFR) with the CKD-EPI 4-level race formula, the fractional excretions of sodium (FeNa) and potassium (FeK), the urine potassium-to-sodium ratio (Na/K urine), and the hemoglobin rate [Hb] were determined for all participants. At the end of IT, eGFR and FeNa increased, respectively, by 22.39% (P0.05). The number of abnormally low eGFR values (0.05) but FeNa decreased by 96.32% (P<0.001) and FeK increased by 144.41% (P<0.001). The [Hb] rate increased by 9.80% (P<0.001), and players had inadequate hydration practice. The results suggested that in addition to its already known effects, TP preserves the positive effects of IT on glomerular function in athletes preparing for a competition that presents a major challenge

Knowledge, Attitude and Practices Regarding Muscular Reinforcement among Judokas in Developing Countries: Case Study of the Republic of Benin

This cross-sectional survey determined the level of knowledge, attitude, and practice about muscular reinforcement (MR) among judokas in the Republic of Benin as typical of a developing country. It also examined the relations between the levels of knowledge, attitude, and practice among these judokas. It was undertaken using a non-probabilistic and exhaustive sample of 79 judokas in the cities of Cotonou and Porto-Novo having a minimum rank of green belt. The levels of knowledge, attitude, and practice were assessed by a questionnaire that comprised 43 items. Information relating to the socio-demographic characteristics and judo practice of the participants were also acquired. The levels among the surveyed judokas were low for knowledge (62 78.5%), attitude (49 62.0%), and practice (49 62.0%). The level of knowledge was significantly associated with attitude and practice for MR (x2= 3.99 p = 0.04 Cramer’s V = 0.22). The association between the levels of attitude and that of practice was non-significant (χ2 = 0.29 p = 0.59). The judokas of developing countries like those in southern Benin would benefit from specific training and participation in more competitions to improve their practice regarding MR and their sports performance

EVALUATION DU RISQUE DE MAJORATION DES ANOMALIES ELECTROCARDIOGRAPHIQUES DE REPOS AU COURS D’UNE EPREUVE D’EFFORT CHEZ DES ARBITRES MASCULINS DE FOOTBALL DU BURKINA FASO / INCREASED RISK ASSESSMENT OF RESTING ELECTROCARDIOGRAPHIC ABNOMALIES DURING EXERCISE TEST AMONG MALE SOCCER REFEREES FRON BURKINA FASO

Introduction : L’activité physique régulière est bénéfique pour la santé cardiovasculaire mais chez les sujets présentant des anomalies à l’électrocardiogramme (ECG) standard, l’effort intense peut s’avérer délétère. Le but de cette étude était de déterminer au cours d’une épreuve d’effort, le risque de majoration des anomalies ECG de repos chez des arbitres de football d’élite et de sub-élite masculins du Burkina Faso. Méthodes : Il s’est agi une étude d’intervention, réalisée avec 18 arbitres, répartis en deux groupes : groupe cas (GCA : n = 7) et groupe contrôle (GCO : n = 11) à profil ECG de repos respectivement anomal et normal. GCA et GCO ont été soumis à une épreuve d’effort maximale suivant un protocole de Bruce avancé. Les profils chronotrope et tensionnel, l’accroissement tensionnel systolique, l’électrocardiogramme d’effort, puis l’échocardiogramme ont été étudiés. La pente d’accroissement tensionnel systolique à l’effort a été déterminée à l’aide de la régression Fc-PAS. Résultats : Les profils chronotrope et tensionnel étaient normaux dans les deux groupes mais la pression artérielle systolique était plus élevée (p = 0,01) dans GCA à la récupération. Dans GCA et dans GCO, la pression artérielle systolique s’est accrue de façon linéaire (p &lt; 0,001) en fonction de la fréquence cardiaque, avec une équation de régression significative (p &lt; 0,001). Deux extrasystoles ventriculaires isolées sont apparues chez un arbitre de GCA mais les résultats échocardiographiques n’étaient pas associés à une pathologie. Conclusion : Les résultats indiquent que les paramètres cardiovasculaires étudiés au cours de l’épreuve, chez les arbitres burkinabè à profil ECG de repos anormal, n’étaient pas associés à une maladie cardiaque. Ils devront être autorisés à participer aux compétitions sportives et suivre un contrôle périodique. Introduction: Regular physical activity is beneficial for cardiovascular health but in subjects with standard electrocardiogram (ECG) abnormalities, intense effort can be harmful. The aim of this study was to determine during a stress test, the risk of increased resting ECG abnormalities in male elite and sub-elite football referees from Burkina Faso. Methods: This was an intervention study, carried out with 18 referees, divided into two groups: case group (CAG: n = 7) and control group (COG: n = 11) with respectively abnormal and normal resting ECG profile. CAG and COG were subjected to a maximal exercise test following an advanced Bruce protocol. Results: The chronotropic and blood pressure profiles, the systolic blood pressure increase, the stress electrocardiogram, then the echocardiogram were studied. The systolic pressure increase slope during exercise was determined using Fc-PAS regression. Chronotropic and blood pressure profiles were normal in both groups but systolic blood pressure was higher (p = 0.01) in CAG at recovery. In both CAG and COG, systolic blood pressure increased linearly (p &lt; 0.001) with heart rate, with a significant regression equation (p &lt; 0.001). Two isolated ventricular extrasystoles appeared in one referee in CAG but the echocardiographic findings were not associated with pathology. Conclusion: The results indicate that the cardiovascular parameters studied during the stress test, in Burkinabè referees with an abnormal resting ECG profile, were not associated with heart disease. They must be authorized to participate in sports competitions and undergo periodic checks.  Article visualizations
