Research background and hypothesis. Replete schedule of competitions and intense training are features of contemporary team sports. Athletes, especially the most involved ones, may not have enough time to recover. As a consequence, aggregated fatigue can manifest in some undesirable form and affect athlete’s performance and health.Research aim. The aim of this study was to evaluate the changes in heart rate recovery (HRR) and investigate possible relations with sport-specifi c measures of effi cacy in professional basketball players during competition season.Research methods. Eight male high-level basketball players (mean ± SD, body mass, 97.3 ± 11.33 kg; height 2.02 ± 0.067 m, and age 23 ± 3.12 years) were investigated. The same basketball specifi c exercise was replicated several times from September till April during the practice sessions in order to assess the personal trends of HRR. Heart rate monitoring was performed using POLAR TEAM SYSTEM. Investigated athletes were ranked retrospectively according to the total amount of minutes played and the coeffi cients of effi cacy. Research results. There were signifi cant differences in the trends of HRR between the investigated players. The most effective players showed decreasing trends of HRR in all cases of ranking.Discussion and conclusions. Research fi ndings have shown that the quality of heart rate recovery differs between basketball players of the same team and could be associated with sport-specifi c effi cacy and competition playing time.Keywords: adaptation, autonomic control, monitoring training.

Dynamic Postural Stability

The production of manifold and rapidly varying movements in team sports requires maintaining an erect posture. This paper aimed to study dynamic postural stability in athletes engaged in team sports. Among the participants were high-level basketball players (n = 15), rugby players (n = 15) and football players (n = 12), as well as 30 young people not professionally involved in sports, all aged 18–21 years. Postural stability was evaluated using stability analyser Stabilan-01 (OKB Ritm, Taganrog). We utilized the Evolventa test, which simulates the real situation of tracking movements in the games, allowing us to quickly assess not only the quality of the athlete’s tracking movement, but also the reserves of maintaining the stability of erect posture. Classical and vector stabilographic characteristics of upright posture stability were analysed. To assess the quality of tracking, special game indicators were used. Athletes demonstrated a significant superiority in the accuracy of performing motor tasks and at the same time in maintaining postural stability over young men not playing sports (p ≤ 0.05). Noteworthy, basketball players had the highest tracking accuracy in the frontal and, especially, in the sagittal plane (p ≤ 0.05). Moreover, basketball players kept their balance much better, surpassing rugby players and, above all, football players in most indicators in both planes (p ≤ 0.05). Thus, the effectiveness, accuracy and speed of completing tasks, as well as fewer errors in high-level athletes were combined with an automated ability, due to the stereotype formed over many years of training, to confidently maintain an upright position even in the most difficult game situations. However, when analysing postural stability, one must take into account the specifics of the sports under study, where a wide variety of ball-handling techniques is combined with competitive activity of the hands or feet.

Son on yılda, resmi müsabaka sırasında yıldız kız basketbolcuların fizyolojik tepkileri ve yüklenme yoğunluğu ile ilgili sınırlı sayıda araştırma rapor edilmiştir. Bu bağlamda, bu çalışmanın amacı, yıldız kız basketbolcuların resmi müsabaka sırasında kalp atım hızı (KAH) yanıtlarını belirlemektir. Çalışmaya 12 yıldız kız basketbolcu (yaş: 14,75±0,55, boy: 168,48±5,30, vücut ağırlığı: 62,6±9,52, tahmini VO²maks: 49,76±3,64 ml/kg/dk) katıldı. KAH ölçümleri resmi bölgesel klüpler lig şampiyonasında alındı. Maçtan iki gün sonra KAH seviyelerini belirlemek için 20 m. Mekik Koşusu Testi (20MKT) uygulandı. Basketbolcuların müsabaka ve 20MKT sırasında kalp atım hızları Polar Team2 (Finland) sistem ile ölçüldü. Elde edilen veriler için frekans analizi uygulandı. Yarılar arasındaki KAH farkı için Wilcoxon Rank Testi kullanıldı. Periodlar arasındaki KAH farkları Friedman’s Testi ile tespit edildi. Analiz sonuçlarına göre, oyuncuların 20MKT sırasında elde edilen maksKAH değerleri 196,33±10.04 olarak tespit edildi. Basketbolcuların tüm müsabaka ortKAH 175,93±10,19 (maks KAH’ın %89.66). İlk yarı ortKAH 177,16±13,19 (maksKAH'ın %90.23), ikinci yarı ortHR 175,00±11,56 (maksKAH'ın 89.13), ilk period ortHR 177,16±13,94 (maksKAH'ın %90.00), ikinci period ortHR 176,87 ± 12,10 (maksKAH'ın %88.88), üçüncü period ortHR 176,88±12,10 (maksKAH'ın %90.08), dördüncü period ortHR 179,40±10,71 (maksKAH'ın %91.73) olarak tespit edildi. Periyotlar ve yarılar arasında ortKAH bakımından anlamlı fark bulunmamıştır (p>0.05). Bu çalışmanın bir sonucu olarak, yıldız kız basketbol müsabakasında KAH cevaplarının maxKAH'ın yaklaşık %89,66 şiddetinde olduğu görüldü. Bu sonuçlar, müsabaka yoğunluğunun tüm yarılar ve periyotlar için çok yüksek olduğunu göstermektedir. Yıldız oyuncuların resmi müsabaka yoğunluğunun belirlenmesi, genç oyuncuların spor performansını geliştirdiklerine dair antrenörlere önemli bilgi sağlayabilir.
