There are many opportunities for athletes to show off their skills, get experience, and have fun in the athletic world. Nowadays, there is a lot of science and math involved in sporting activities, from biomechanics and physiology to nutrition and sociology to psychology and computer science to growth and development and sports medicine, among several other disciplines. Recognising potential, being fit, and training using scientific techniques are all necessities of international sports. Athletes' exceptional performances are influenced by several factors such as their genetics, physical condition, training, skill level, biomechanics, and psychology. As stated by Conway et al. (2010). A number of nations are sending their best athletes to show the world who's boss. Athletes' strength, stamina, and ability have been tested to their limits as they've been driven to run faster, more nimble, and more flexible by the national spirit.

Because of their inherent competitiveness, athletes from all areas of life are always pushing themselves to set new marks. In addition, there is a constant quest for innovative methods by which coaches may improve their players' performance. Physical education instructors, coaches, fitness experts, and others in the athletic and active professions depend significantly on their knowledge of exercise physiology in their daily job. Modern exercise physiology, biomechanics, and psychological tools are many for researchers to choose from. This may be useful for fitness experts, instructors, and trainers in the field as it allows them to collect and exchange data on people's exercise and physical activity levels. It could be useful for the scientific design and implementation of training and exercise programs for athletes of all types.

Athletes should pay close attention to their pre-exercise diets since they have a significant impact on vital physiological variables including heart rate, exercise capacity, VO2 max, and oxygen saturation. A lot of people are interested in the dietary approach of drinking a sports drink before exercise. The reasoning behind this is that it will help you utilise energy more efficiently, delay fatigue, and have a better workout overall. Despite ongoing research, there is currently no consensus on how long it is best to wait after drinking a sports drink before engaging in physical performance. Sports drinks, which could include carbohydrates, electrolytes, and other performance-enhancing ingredients, primarily serve to hydrate the user, regulate electrolyte levels, and replace glycogen stores. Important for promoting physical activity over the long term and mitigating performance declines, these factors must be present. Knowing how the body responds to different amounts of fluids before exercise could be very helpful for coaches, athletes, and sports nutritionists.

We want to get a better understanding of the relative benefits of consuming sports drinks at various pre-game intervals from this study. The duration of the advantages of pre-workout beverages is a question that researchers are attempting to answer by examining several aspects. Also, the effects of pre-workout supplements on outcomes will be examined, taking into account factors like training history and individual physiological variances.

The findings of this research have the potential to inform the development of evidence-based nutrition plans that can benefit athletes across different sports. Gaining an advantage and enhancing exercise efficiency in the pursuit of peak athletic performance requires an understanding of the nuances of when to drink before activity.

Selection of subjects

The study's participants were 45 students chosen at random from the Physical Education program at Devi Ahilya Vishwavidyalaya in Indore. The participants' ages varied from eighteen to twenty-five. Using a randomisation procedure, these people were separated into three groups of fifteen each. We called the three sets of participants "Group A," "Group B," and "Control Group C" respectively. Each group received a different beverage in order to study the impact of various fluids on physiological performance measures. As a control, Group C got ordinary filtered water, Group B got freshly squeezed lemon juice, and Group A got Gatorade, a commercially available sports drink.

Experimental Design

A randomized group design was implemented to ensure objective results and minimize bias. Initially, all 45 subjects were randomly allocated into three groups. Sports drinks were also randomly assigned to each group to reduce any influence of selection bias. This design allowed for a comparative analysis of how different types and timings of fluid intake affected exercise performance and physiological response.

Description of Sports Drinks Administered

·                     Gatorade (Group A): Commercially available sports drink (orange flavor), 500 ml per serving.

·                     Fresh Lemon Juice (Group B): Prepared by mixing 500 ml filtered water with 10 ml lemon extract, 30 grams sugar, and 1 gram salt.

·                     Plain Water (Group C): 500 ml of UV-filtered water.

Statistical procedures

We used the right statistical methods to look at the differences within and between the groups. To evaluate differences among groups between the pre- and post-tests, the paired t-test was used. To make sure the treatment effects were accurately interpreted, Analysis of Covariance (ANCOVA) was used to compare the three groups' means, with pre-test scores adjusted for as variables. When it came to examining disparities between groups, one was more suited than the other.

Analysis of heart rate: pre- and post-test comparisons (1 hour before exercise)

Table 1: Paired Sample t-Test on Heart Rate Measurements Before and After Games Workout When drinks were administered 1 hour prior to exercise

*Significant at 0.05 level

All three groups' heart rates decreased considerably after each recorded period following the games activity, according to the paired t-test results: Gatorade Group: Significant reductions were observed immediately after exercise (t = 9.50), at 2 minutes post (t = 10.51), and at 5 minutes post (t = 6.05). These results suggest Gatorade had a consistent effect in supporting heart rate recovery across all time points. Lemon Juice Group: The t-values for immediate (5.62), 2 minutes (3.94), and 5 minutes post-exercise (3.38) were also statistically significant, indicating a beneficial effect on heart rate reduction, though the effect size was slightly lower compared to the Gatorade group. Control Group (Water): Surprisingly, even plain water led to significant heart rate reductions (t-values = 8.29, 3.30, and 8.41). While effective, the trends suggest a slightly less consistent or sustained impact than Gatorade.

*Note: Low statistical significance (p < 0.05). For df(2,42) and df(2,41), the F ratio needed for significance at the 0.05 level is 3.22.

The groups administered the Gatorade drink (93.8 ± 1.32), the lemon juice (93.67 ± 1.23), and the control (93.8 ± 1.26), were given the pre-test oxygen saturation mean and standard deviation, respectively. At 0.05, the estimated F-value fell short of the 3.22 crucial table F-value. This proves that the random assignment of participants worked as there was no discernible variation in oxygen saturation among the three groups before the beverages were given.

*Note: Insignificant at the 0.05 level. The F ratio for significance at the 0.05 level for df(2,42) and df(2,41) is 3.22.

Pre-Test Observations

The control group had a heart rate of 131 ± 5.56 beats per minute, the group given Gatorade a heart rate of 130.6 ± 4.96 beats per minute, and the group given fresh lemon juice a heart rate of 130.73 ± 5.87 beats per minute. Compared to the necessary table F value of 3.22, the computed F value of 0.02 was much lower. This result verifies that there were no notable variations in heart rates across the three groups prior to drink delivery, suggesting that individuals were successfully randomised.

Post-Test Observations

Post-test heart rate means and standard deviations were recorded as: Gatorade drink group at 123.67 ± 5.82, fresh lemon juice group at 124.53 ± 4.34, and control group at 125.2 ± 5.74. The computed F value of 0.31 was less than the table F value of 3.22, showing no significant variation. This suggests that consuming Gatorade, fresh lemon juice, or water four hours prior to the workout had no substantial effect on heart rate immediately after the games workout.

Adjusted Post-Test Observations

Following the test, the groups whose heart rates were adjusted showed the following: the control group (125.2), the Gatorade drink group (123.67), and the fresh lemon juice group (124.53). At the 0.05 threshold of significance, the computed F-value of 0.38 was not significant, as it was lower than the table F-value of 3.22. Heart rate after exercise was unaffected by drinking Gatorade, fresh lemon juice, or water four hours before to the exercise, according to the data.

Figure 3: Heart Rate Pre-, Post-, and Adjusted Post-Workout Comparison of Heart Rate Two Minutes After Workout Among Experimental and Control Groups (Following Drink Administration 4 Hours Before Exercise)

To evaluate the impact of pre-workout drinks on heart rate recovery, data were collected from three groups those who consumed Gatorade, fresh lemon juice, and plain water (control) with heart rate recorded two minutes post-exercise. The analysis involved comparing pre-test, post-test, and adjusted post-test means using ANCOVA.

Note: The critical F-value at the 0.05 level for df(2,42) and df(2,41) is 3.22. All observed F-ratios were below this threshold, indicating statistical insignificance.

Pre-Test Comparison: The pre-test oxygen saturation means for the Gatorade (95.8 ± 0.77), lemon juice (95.73 ± 0.88), and control (95.87 ± 0.74) groups showed no statistically significant differences. The calculated F-value of 0.10 was far below the critical F-value of 3.22. This supports the assumption that participants were randomly and evenly distributed among the groups prior to the intervention.

Post-Test Analysis: Two minutes after the workout, the post-test means recorded were 95.87 ± 0.74 (Gatorade), 95.93 ± 0.96 (lemon juice), and 96 ± 0.92 (control). The F-ratio of 0.09 also fell below the significance threshold, indicating that the consumption of different drinks had no significant impact on post-exercise oxygen saturation at this interval.

Adjusted Post-Test Outcomes: After adjusting for covariates, the oxygen saturation means were 95.87 (Gatorade), 95.97 (lemon juice), and 95.96 (control). The F-ratio remained low at 0.10, confirming the absence of statistically meaningful differences between the groups even after adjustments. Thus, the findings suggest that drinking Gatorade, lemon juice, or water four hours before exercise does not produce a significant effect on oxygen saturation measured two minutes post-workout.

Assessment of exercise capacity at baseline and post-workout in experimental and control groups

Table 5: Paired t-Test Analysis of Exercise Capacity After a Games Workout (Drinks administered 4 hours before workout)

*Note: No significance at the 0.05 level (calculated t below tabulated t of 1.76).

Gatorade Drink Group

For the Gatorade group, the baseline exercise capacity mean and standard deviation were 708.73 ± 43.07, with post-test values at 703.53 ± 45.67. The calculated t-value of 1.28 is below the tabulated t-value of 1.76, indicating no significant difference. This suggests that consuming Gatorade four hours before a games workout had no notable impact on exercise capacity.

Fresh Lemon Juice Group

In the fresh lemon juice group, the baseline mean and standard deviation were 706.13 ± 65.80, and post-test values were 705.47 ± 65.79. The calculated t-value of 1.62 is less than the tabulated t-value of 1.76, showing no significant change. Thus, the administration of fresh lemon juice four hours prior to the workout did not significantly affect exercise capacity.

Water (Control) Group

For the control group (water), the baseline mean and standard deviation were 707.53 ± 53.93, with post-test values at 706.8 ± 47.34. The calculated t-value of 0.06 is well below the tabulated t-value of 1.76, confirming no significant difference. This indicates that water consumption four hours before the workout had no substantial effect on exercise capacity.

*Note: No significance at the 0.05 level (calculated t below tabulated t of 1.76).

Gatorade Drink Group

In the Gatorade group, the baseline VO2 max mean and standard deviation were 49.42 ± 2.62, with post-test values at 49.58 ± 2.74. The calculated t-value of 0.20 is well below the tabulated t-value of 1.76, indicating no significant difference. This suggests that consuming Gatorade four hours before a games workout had no notable impact on VO2 max.

Fresh Lemon Juice Group

For the fresh lemon juice group, the baseline mean and standard deviation were 49.01 ± 3.72, and post-test values were 49.40 ± 3.75. The calculated t-value of 0.95 is less than the tabulated t-value of 1.76, showing no significant change. Thus, the administration of fresh lemon juice four hours prior to the workout did not significantly affect VO2 max.

Water (Control) Group

In the control group (water), the baseline mean and standard deviation were 48.63 ± 2.96, with post-test values at 48.83 ± 2.72. The calculated t-value of 1.74 is slightly below the tabulated t-value of 1.76, confirming no significant difference. This indicates that water consumption four hours before the workout had no substantial effect on VO2 max.

Figure 6: VO2 Max Pre- and Post-Workout

The study revealed that the timing of pre-exercise ingestion of Gatorade, lemon juice, or water did not yield significant differences in performance or oxygen metrics, except for heart rate, which improved across all groups. These outcomes suggest that while heart rate may be sensitive to hydration and rest, neither drink type nor timing had a substantial impact on overall aerobic performance or oxygenation. Based on these results, it is recommended that future studies be conducted with larger sample sizes, across different age groups and sexes, and by incorporating additional variables.
