Speed And Accuracy

Background: The importance of the serve in tennis players’ performance is well known but no previous studies have analyzed the effects of both physical and cognitive fatigue on the speed and accuracy of the serve. This study analyzed the effect of a High-Intensity Interval Training (HIIT) with and without cognitive load on serve speed and accuracy, spirometry, and strength manifestation. Methods: 32 recreational players (25 men and 7 women; aged 21.40 ± 1.52 years) performed a HIIT and a HIIT with a Stroop in recovery phases before performing a series of tennis services. Speed and accuracy of the services, spirometry, and strength manifestations were registered. Results: The main findings of the study showed that strength manifestations and spirometry were not affected by either protocol. A decrease in serve speed was observed in both protocols (p < 0.001) but service accuracy did not show impairments (p = 0.66). Conclusion: A combination of physical and mental fatigue may decrease serve speed but will not affect strength manifestations or spirometry negatively. These results could be caused by a response of the central nervous system to maintain the accuracy of the ball in presence of fatigue.

Intensity Training

Purpose:To compare the effects of combining high-intensity training (HIT) and sport-specific drill training (MT) versus sportspecific drill training alone (DT) on fitness performance characteristics in young tennis players.Methods:Twenty young tennis players (14.8 ± 0.1 y) were assigned to either DT (n = 10) or MT (n = 10) for 8 wk. Tennis drills consisted of two 16- to 22-min on-court exercise sessions separated by 3 min of passive rest, while MT consisted of 1 sport-specific DT session and 1 HIT session, using 16–22 min of runs at intensities (90–95%) related to the velocity obtained in the 30–15 Intermittent Fitness Test (VIFT) separated by 3 min of passive rest. Pre- and posttests included peak oxygen uptake (VO2peak), VIFT, speed (20 m, with 5- and 10-m splits), 505 Agility Test, and countermovement jump (CMJ).Results:There were significant improvements after the training period in VO2peak (DT 2.4%, ES = moderate; MT 4.2%, ES = large) and VIFT (DT 2.2%, ES = small; MT 6.3%, ES = large) for both DT and MT, with no differences between training protocols. Results also showed a large increase in the 505 Agility Test after MT, while no changes were reported in the other tests (sprint and CMJ), either for MT or DT.Conclusions:Even though both training programs resulted in significant improvements in aerobic performance, a mixed program combining tennis drills and runs based on the VIFT led to greater gains and should be considered the preferred training method for improving aerobic power in young athletes.

EFEKTIVITAS HIGH INTENSITY INTERVAL TRAINING (HIIT) TERHADAP HEART RATE VARIABILITY (HRV) PADA OVERWEIGHT DAN OBESITAS     Desak Made Wahyu Ariningsih   Program Studi Fisiologi Olahraga, Fakultas Kedokteran, Universitas Udayana Jalan PB Sudirman, Denpasar, Bali, Indonesia Email: [email protected]   ABSTRAK Overweight dan Obesitas dikaitkan dengan disfungsi sistem saraf otonom yang menjadi salah satu pertimbangan adanya penyakit jantung, penurunan aktivitas saraf parasimpatis, dan peningkatan aktivitas saraf simpatis yang merupakan pola tidak menguntungkan pada jantung. Pengukuran kinerja sistem saraf otonom dapat dilakukan secara invasif melalui penilaian Heart Rate Variability (HRV). Penurunan nilai HRV pada obesitas berhubungan dengan berat badan dan kadar lemak yang lebih tinggi. Pemberian latihan telah terbukti meningkatkan modulasi vagal, meningkatkan HRV, dan mengurangi aktivitas saraf simpatis serta kadar plasma katekolamin. Pemberian High Intensity Interval Training (HIIT) pada overweight dan obesitas direkomendasikan karena memiliki efektivitas terhadap peningkatan kerja saraf otonom melalui penurunan berat badan atau massa lemak tubuh serta stimulasi dan inhibisi enzim yang berpengaruh pada kinerja sistem saraf simpatis dan parasimpatis. Keseimbangan sistem kerja pada saraf simpatis dan parasimpatis akan memberikan efek kardioprotektif untuk mengurangi risiko penyakit jantung.    Kata Kunci : High Intensity Interval Training, Sistem Saraf Otonom, Heart Rate Variability     ABSTRACT    Overweight and obesity are associated with autonomic nervous system dysfunction that is one of the considerations for heart disease, decrease parasympathetic activity, and increase sympathetic activity, which is an unfavorable pattern to the heart. Autonomic nervous system measurement can be done in an invasive manner through the assessment of Heart Rate Variability (HRV). Decreased HRV values ??in obesity are associated with higher body weight and fat mass. Exercise has been shown to increase vagal modulation, increase HRV, and reduce sympathetic nerve activity and catecholamine plasma levels. Giving High Intensity Interval Training (HIIT) to overweight and obesity is recommended because it has effectiveness in increasing the work of autonomic nerves through weight loss or body fat mass loss also through stimulation and inhibition of enzymes that affect the performance of the sympathetic and parasympathetic nervous systems. The balance of the work system on the sympathetic and parasympathetic nerves will provide a cardio protective effect to reduce the risk of heart disease.   Key Words : High Intensity Interval Training, Autonomic Nervous System, Heart Rate Variability

Practical Implications

The maximal running speed (MRS) achieved in the 30-15 International Fitness Test (30-15IFT) is widely used to prescribe high-intensity interval training (HIIT). The 30-15IFT can be performed in either 40- (30-15IFT-40) or 28-meters (30-15IFT-28) length. Objectives: The aim of this study was to evaluate the MRS achieved in the 30-15IFT-40 and the 30-15IFT-28. Methods: Fifty U-18 players from different sports (handball: n=19, soccer: n=19, tennis n=12) attended two testing sessions. Results: MRS did not differ between the 30-15IFT-40 and the 30-15IFT-28 in either handball or soccer players. However, tennis players showed significantly greater MRS values in the 30-15IFT-28 than in the 30-15IFT-40 (20.80±1.87 vs 20.05±2.09 km·h-1; p = 0.030; ES = 0.38). In addition, tennis player showed significant greater MRS in the 30-15IFT-28 (20.80±1.87 km·h-1) than both handball (18.58±1.13 km·h-1; p < 0.001; ES = 1.53) and soccer players (18.74±0.93 km·h-1; p = 0.001; ES = 1.47). Conclusions: The different MRS values in the 30-15IFT-40 and the 30-15IFT-28, entail significant practical implications for HIIT prescription in tennis players.
