Paragraph 1: Specific Aims Muscle fatigue is the most common symptom athletes experience when training or actively competing. It inhibits their ability to perform to the fullest and decreases their chances of having a successful game, event, or practice. Endurance sports such as cycling, swimming, and long-distance running require a longer time to exhaustion which many athletes lack. Due to the accumulation of H+ and
reduction in sarcoplasmic pH, fatigue is the result which is caused by training (Lino et al., 2021). In order to improve their performance, athletes push themselves, or are pushed, to the point of exhaustion and beyond, which can cause overreaching and overtraining, which affects 30-60% of nonelite and elite endurance athletes (Chung., 2021). Many studies have researched the effects of sodium bicarbonate (SB) as a buffer on high-intensity training lasting from seconds to a couple of minutes, which showed an improvement of 2-3% in performance measures such as power, speed, work capacity, and time to failure (Siegler et al., 2016). What these studies fail to present is whether or not the effects of sodium bicarbonate
supplementation can decrease early muscle fatigue and improve muscle strength in female endurance athletes. Thus, there is an urgent need to test this supplementation to determine a delay in H+ accumulation and an increase in overall strength which can be measured by testing blood pH and a 1 RM (Repetition maximum). Paragraph 2: Our long-term goal
is to decrease early-onset muscle fatigue and increase muscle strength in female endurance athletes. Research containing supplementation dose, preparatory time, and benefits is lacking for female endurance athletes. The suggested dose for male endurance athletes was found to be 0.1-0.3 g. kg-1. BW. Dose recommendation has many factors that lead to its determination since there have been reported side effects, but studies found that “0.3 g · kg–1 BW NaHCO3 increased cycling performance (based on time until exhaustion) and increased lactate levels during the pre-and postexercise period” (Ferreira, et al., 2019). The objective of this application
is to analyze muscle fatigue and muscle strength with the supplementation of sodium bicarbonate in female endurance athletes to determine any benefits that may derive from this supplement. Our central hypothesis
is that when sodium bicarbonate is
consumed 60-180 minutes before exercise increased time to fatigue and muscle strength can be observed over the course of three to seven days. Our hypothesis is based on research showing a decrease in early muscle fatigue and an increase in muscle strength, and power. Long-term supplementation of sodium bicarbonate may improve training adaptations. The rationale for the proposed research
is that early muscle fatigue is a common issue that most endurance athletes face which can inhibit their performance and results. By analyzing sodium bicarbonate supplementation in female endurance athletes, many other endurance athletes can be informed and enjoy the benefits/ physical enhancements that come with taking sodium bicarbonate before a competition.
Paragraph 3: We plan to test our hypothesis and thereby accomplish the objective of this application by pursuing the following specific aims
.
1.
The primary aim is to determine if supplementing sodium bicarbonate can decrease the time to exhaustion in order to prevent early muscle fatigue in female endurance athletes. It is hypothesized that by taking 0.1- 0.3 g. kg- BW of SB 60-180 minutes before exercise will result in a decrease in early muscle fatigue.
2.
The secondary aim is to analyze muscle strength with the supplementation of sodium bicarbonate after the prescribed exercise protocol (strength-based and aerobic). It is hypothesized that taking this supplement can improve exercise performance because of the physiological effects of SB.
Paragraph 4:
With respect to expected outcomes
, by analyzing these physiological changes that come from supplementing sodium bicarbonate, female endurance athletes are able to enjoy the same benefits that their counterparts have with research that proves equal advantage.
