Equation for analyzing the peak power in aquatic environment: An alternative for olympic rowing athletes.

ABSTRACT:

Purpose

To develop an equation to provide the peak power (PP) through a specific stimulus performed in an aquatic environment, as well as to correlate morphological, anthropometric and strength variables with rowing performance.

Methods

The sample consisted of 16 elite young rowing athletes of both sexes (15.7 ± 1.21 years). The strength of upper limbs and lower limbs was verified. To analyze the PP, a 100-m Sprint test was performed on an indoor rowing type ergometer, and after a 72-hour wash-out, the test was repeated in an aquatic environment on a vessel equipped with a global position system. Body composition was analyzed by examining bone densitometry with an X-ray source and maturation was verified by anthropometry.

Results

The tests for water sprint and indoor rowing showed significant reliability (ICC = 0.695; p = 0.0007). The PP aquatic showed reliability with that acquired in indoor rowing (ICC = 0.897; p<0.0001) and was related to maturation (p<0.05). The morphology, anthropometry and strength of the upper limbs were related to the sprint and peak strength in both tests (p<0.05).

Conclusion

The equation for the PP in aquatic environment presented by the present study is highly reliable with an indoor ergometer digital ergometer.

Project description:IntroductionElite and Olympian athletes are often stretching the upper limits of normal physiology and biomechanics of the musculoskeletal system in their efforts to excel in their sport. For them to get back to their sport at the same level after injury, the management, repair techniques, and rehabilitation protocols should be robust to permit healing of tissues to allow supra-normal loading and performance. The knee and the meniscus are commonly injured in these sports. Yet, the incidence, mechanisms, types of injuries to the meniscus, and their management are not known across different sports in the Olympics.MethodsWe set out to look into the incidence and the trends of publications on meniscal injuries of the knee in Olympic games. A search of the PubMed and Scopus for these injuries using a search strategy gave 79 and 116 articles, respectively.ResultsThere were very few publications giving the incidence of meniscal injuries in the Olympics. Football is the sport with the highest rate of meniscal injuries. Different sports are popular in different countries, and depending on the popularity and the country reporting these injuries, incidences differed. There was data available from India and Brazil for Elite athlete from diverse sports, whereas most data from other countries were for football and soccer. Knee was found to be the second most commonly injured part of the body in both Winter and Summer Olympics as well as the Youth Winter Olympics. Data were not available from the Youth Summer Olympics to make any conclusions. The number of publications on this topic is low. We presented the timeline of publications and citations of articles on this topic. The top country, language, journal, university, and author were USA, English, American Journal of Sports Medicine, Hospital of Special Surgery in New York and Brophy RH, respectively. The data on the risk factors for meniscal injuries were analyzed, discussed, and presented for football, as this was the most extensively studied sport.ConclusionsEven though the knee is one of the commonly injured anatomical locations in elite athletes, there is a lack of literature on meniscal injuries in this subset of population. We looked at possible reasons and made recommendations to improve data collection on these injuries.

Project description:BackgroundAthletes can experience exercise-induced transient arrythmias during high-intensity exercise or competition, which are difficult to capture on traditional Holter monitors or replicate in clinical exercise testing. The aim of this study was to investigate the reliability of a portable single channel ECG sensor and data recorder (PluxECG) and to evaluate the confidence and reliability in interpretation of ECGs recorded using the PluxECG during remote rowing.MethodsThis was a two-phase study on rowing athletes. Phase I assessed the accuracy and precision of heart rate (HR) using the PluxECG system compared to a reference 12-lead ECG system. Phase II evaluated the confidence and reliability in interpretation of ECGs during ergometer (ERG) and on-water (OW) rowing at moderate and high intensities. ECGs were reviewed by two expert readers for HR, rhythm, artifact and confidence in interpretation.ResultsFindings from Phase I found that 91.9% of samples were within the 95% confidence interval for the instantaneous value of the changing exercising HR. The mean correlation coefficient across participants and tests was 0.9886 (σ = 0.0002, SD = 0.017) and between the two systems at elevated HR was 0.9676 (σ = 0.002, SD = 0.05). Findings from Phase II found significant differences for the presence of artifacts and confidence in interpretation in ECGs between readers' for both intensities and testing conditions. Interpretation of ECGs for OW rowing had a lower level of reader agreement than ERG rowing for HR, rhythm, and artifact. Using consensus data between readers' significant differences were apparent between OW and ERG rowing at high-intensity rowing for HR (p = 0.05) and artifact (p = 0.01). ECGs were deemed of moderate-low quality based on confidence in interpretation and the presence of artifacts.ConclusionsThe PluxECG device records accurate and reliable HR but not ECG data during exercise in rowers. The quality of ECG tracing derived from the PluxECG device is moderate-low, therefore the confidence in ECG interpretation using the PluxECG device when recorded on open water is inadequate at this time.
