Book excerpt: ABSTRACT: Heart rate variability (HRV) measurements vary depending on a person's body position. The purpose of this study was to compare the postural effects on HRV between Division III swimmers and Division III runners. This was an experimental and cross-section study. Division III swimmers and cross-country runners (N = 29), ages 18 to 22 years old, participated in an orthostatic stressor while HRV measurements were taken after 10 minutes of laying down, immediately standing, and after 10 minutes of continued standing. Three separate 2x3 mixed factorial ANOVAs were used for heart rate (HR), low frequency to high frequency (LF/HF) ratio, and high frequency (HF) measurements, to compare the two types of athletes across the three time points. For both types of athletes HR significantly increased when comparing 10 minutes of supine to immediately standing (p

This book was released on 2014 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: It is important for elite endurance athletes to have practical and reliable means of measuring fatigue throughout their training. Variations in Autonomic Nervous System activity (ANS) may provide an effective marker of fatigue and of recovery. ANS control of heart rate is well known to be affected by exercise training, and those adaptations can be determined using measures of heart rate variability (HRV). Previous research has examined the effect of training on HRV and ANS control of heart rate in males, there is a lack of any comprehensive studies that address adaptations in female athletes. Therefore, the purpose of this study was to investigate the changes in HRV and ANS fluctuations in female swimmer athletes throughout an entire collegiate swim season. 9 Division I female swimmers (Age: 20.6±1.01) were used to determine HRV at three different points in their competitive training: pre-season, mid-season, and post-season. During each testing session, HRV was measured both at rest and during a maximal 400 yd freestyle swim. Heart rate values were determined using Polar heart rate monitors, and the HRV analyses was conducted using Kubios 2.0 HRV analysis software. Global ANS balance was shown to significantly shift towards Sympathetic (SNS) predominance during the mid-season testing and significantly shift towards parasympathetic (PNS) predominance during post-season testing. HRV analysis appears to be an appropriate tool to monitor the effects of physical training loads on performance and fitness in female athletes, and it can be used to help identify and prevent overtraining states.

Download or read book The Influence of Sleep and Heart Rate Variability on the Occurrence of Injuries Illnesses and Missed Participation Days in NCAA Collegiate Swimmers written by Bruin Armwald and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Athlete populations are at an increased risk of suffering an injury or illness due to their high level of physical activity. Additionally, athletes may not attain adequate bodily recovery following their training and/or competition sessions. This is particularly true of collegiate athletes who balance the demands of their sport with academic responsibilities. Recent innovations in wearable technology have allowed researchers to track specific recovery metrics such as sleep and heart rate variability. This study utilized the WHOOP Performance Optimization System to measure sleep and heart rate variables in a group of 11 NCAA Division 1 swimmers (Males= 8, Females= 3) for the duration of their season. Data related to covariables including training load and body composition were also recorded. Outcomes of interest were injuries, illnesses, and missed participation days. Descriptive statistics as well as stepwise logistical regression were used to discern the influence of predictor variables on the occurrence of adverse health events. Ten athletes completed data collection and were used for analysis. Average total sleep time was 6.51 ( 0.23) hours, and average HRV was 78.08 ( 7.54) ms. Regression analysis identified total sleep as a significant predictor of illnesses (OR= 0.70, 95% CI= 0.55-0.89, P

This book was released on 2015 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: New technology continuously develops to assist with enhancing athletic performance. Assessing the physiological responses athletes experience from training is crucial when developing programs to simultaneously optimize performance and improve fitness levels. By combining coaching expertise with scientific technology, coaches can monitor and obtain their athletes' individual objective physiological responses (i.e. heart rates) on the effectiveness of the applied external stimuli or training program(s). PURPOSE: To examine the physical training doses through heart rate monitoring of strength and condition (S&C) sessions compared to a typical game setting in female soccer and basketball collegiate athletes. METHODS: Participants were nine female soccer players [age: 20.5 +/- 0.34 yr., height: 172.2 +/- 1.25 cm, mass: 66.8 +/- 1.72 kg, BMI: 22.6 + 0.34] and nine female basketball players (mean + SD) [age: 20.3 +/- 0.33 yr., height: 178.4 +/- 2.27 cm, mass: 73.3 +/- 3.43 kg, BMI: 22.9 + 0.78] from a NCAA Division I university. Participants wore a heart rate chest strap monitor during the summer S&C training sessions and preseason games. Each subject's height, weight, age-predicted max heart rate, and player position were recorded into Polar Team2 Pro system. After each training session and game, each subjects' data from the transmitter was uploaded for analysis. Data was subsequently analyzed to determine the training load (TL), average calories expended per minute (kcal/min), average heart rate, maximum heart rate, and percent of time spent in each training zone (Z1-Z5) for the selected S&C sessions (T1 and T2) and one pre-season game (T3). RESULTS: One-way ANOVA with repeated measures detected significant differences in the women's soccer TL with post hoc comparisons revealing the TL in T3 (239.1 +/- 112.4) was higher than T1 (147.1 +/- 63.4) and T2 (149.6 +/- 36.4) and percent time in Z3 was lower in T3 (13.7 +/- 2.7) compared to T1 (22.5 +/- 6.5) and T2 (21.7 +/- 8.1). One-way ANOVA with repeated measures detected significant differences in the women's basketball kcal/min, average heart rate and percent of time spent in Z1-Z5. Post hoc comparisons revealed T3 had the lowest values in both kcal/min (9.7 +/- 3.0) and average heart rate (133.8 +/- 16.8). T1 had the greatest amount of time spent in Z4 (25.9 +/- 10.0) and Z5 (32.8 +/- 21.1) and the least amount of time spent in Z1 (13.0 +/- 22.1) and Z2 (12.9 +/- 9.0). T2 had the highest percent time spent in Z2 (12.9 +/- 9.0) and Z3 (20.1 +/- 6.3). T3 had the greatest percent time spent in Z1 (13.0 +/- 22.1) and the least amount of time spent in Z3 (11.3 +/- 6.3) and Z4 (15.2 +/- 7.1). CONCLUSION: Summer strength and conditioning sessions for soccer produced physiological responses that were relatively similar to the responses experienced in preseason games. However, summer strength and conditioning sessions for basketball had similar training loads to preseason games but it did not replicate the physiological responses in preseason games. Heart rate monitoring systems may be useful in helping strength and conditioning coaches and the sport coaches to quantify physiological responses to game and practice sessions in their athletes.

Download or read book Sport Training Individualization written by Alexander P. Isaev and published by Nomos Verlagsgesellschaft. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the essence of sports training, new concepts and technologies, the prerequisites and scope of an individualised approach to training as well as how to integrate the main methodological paradigms of sports training systems using the theory of adaptation. Modernisation and analysis of a body's potential plus features of efficient adaptation make it possible to adjust training loads and to ensure excellent sporting performances, particularly with the help of artificially controlled training environments. This book suggests the use of modern training methods in endurance sports. For example, it shows the benefits of focused application of exercises in developing local and regional muscular endurance, and provides recommendations on training for important competitions. It also describes the peculiarities of short-term reactions and the long-term adaptation of athletes to the techniques mentioned and to a higher level of performance.
