Brief Summary:
To overcome the lack of knowledge regarding the impact of different living low training high methods on swimming performance a 4-week intervention will be carried out to determine and compare the effects of three Repeated Sprints in Hypoxia RSH methods with each other and with a control group Our goal is to characterize and compare the adaptations in swimming performance and in cardiorespiratory metabolic and muscle oxygenation responses that can arise after a 4-week training period of RSH and RSH-voluntary hypoventilation VHL performed in a ski-ergometer
Detailed Description:
Recently several new living low training high LLTH methods involving repeated sprints in hypoxia have shown promising results especially in team sports However the underlying mechanisms remain mostly unclear as does its effectiveness in improving swimming performance
Hypoxemia can be induced by exposure to ambient hypoxia conditions by voluntary hypoventilation at low lung volume or by vascular occlusion namely blood flow restriction Swimming performance is influenced by aerobic and anaerobic metabolism and could benefit from these different LLTH methods
This project aims to compare the effects of repeated sprint training performed with a ski-ergometer 1 in a hypoxic chamber and 2 with voluntary hypoventilation on the performance of swimmers as well as to characterize cardiorespiratory metabolic and muscle oxygenation adaptations that may contribute to the improvements achieved after four weeks of each of these types of training
All groups will be evaluated before and after the supervised training period in three testing sessions in normoxia separated by at least 24 hours within 7 days Swimmers will perform 1 time-trial 100 m front crawl in the swimming pool to determine performance VO2 peak and lactate concentration following the test 2 incremental test to exhaustion in the swim-ergometer to determine aerobic peak power cardiorespiratory responses VO2max ventilatory thresholds and maximal tissue deoxygenation 3 time-trial test in the ski-ergometer 100 m to access performance muscle and pulmonary oxygen uptake kinetics and the relative contribution of energetic systems
Training sessions will be performed in the ski-ergometer and consist of 4 sets of 5x6s all-out sprints with 24s and 5 min of passive rest between the sprints and sets respectively In all testing and training sessions pulse oxygen saturation will be measured for safety purposes
