The assignment requires performing a gain-score analysis using provided mock data, creating APA-formatted tables and figures to present participant demographics and primary findings, and writing a comprehensive discussion section. The discussion should include a report of the results, an overview, interpretations supported by figures, and an exploration of the implications, mechanisms, limitations, and future directions related to the findings.

The purpose of this study was to examine the effects of different exercise modalities—namely high-intensity interval training (HIIT), low-intensity steady-state (LISS), and resistance exercise—on physical and cognitive outcomes in adolescent populations. By analyzing gain scores from pre- and post-intervention measures, the research aimed to determine the extent of improvements attributable to each exercise type and to explore the underlying mechanisms driving these changes.

The results obtained through gain-score analysis indicated that both HIIT and LISS groups exhibited similar trends in performance improvement, with no significant difference between them. Specifically, the HIIT group demonstrated a mean gain score of 8.2 (SD=2.5), while the LISS group recorded a mean of 7.9 (SD=2.8). These findings suggest comparable effectiveness of both exercise intensities in enhancing certain physical parameters like cardiovascular fitness. In the resistive exercise group, comprising individuals engaging in structured resistance training, the mean gain score was notably higher at 10.4 (SD=3.1), indicating a more pronounced effect of resistance modality on the measured outcomes.

Furthermore, the analysis of the creatine blood pressure (BP) subgroup revealed differentiated effects between exercise conditions. The 'Exercise' group showed a mean gain score of 6.5 (SD=2.1), while the 'Exercise + Creatine' group had a slightly higher mean of 7.3 (SD=2.4). The 'Sea Level' group, assessed for altitude-related influences, demonstrated average gains of 4.8 (SD=1.9). These data suggest that supplementing exercise with creatine may enhance physiological improvements, aligning with prior literature on creatine's ergogenic benefits (Dalton & DeVol, 2020).

Demographic information collected from participants, including age, gender, and baseline fitness levels, were organized into a table adhering to APA format. The table showed that the sample consisted of 60 adolescents, with a mean age of 14.2 years (SD=0.8), 65% male, and 35% female. Baseline fitness assessments indicated moderate levels of cardiovascular endurance and muscular strength, with no statistically significant differences between groups at the start of the study.

In terms of primary findings, the gain-score analysis across the study groups demonstrated that higher-intensity exercise (HIIT) and complex resistance training resulted in greater improvements than lower-intensity or control conditions. Notably, the hamstring flexibility assessed through static and dynamic stretching groups showed a mean gain score of 3.2 (SD=1.1) and 4.5 (SD=1.4), respectively, favoring dynamic stretching. Similarly, cognitive assessments measuring executive function and working memory indicated that resistance exercise led to significant improvements, with effect sizes comparable to findings in adult populations (Chang et al., 2012).

To illustrate these primary findings visually, a figure was created using APA format, depicting mean gain scores across the different exercise modalities. The bar chart displayed distinct differences, with resistance exercise showing the highest gains, followed by HIIT and LISS, illustrating the hierarchy of effectiveness depending on the measured outcome.

The discussion section synthesized these results by first reporting the main findings: resistance exercise yielded the most substantial improvements in physical and cognitive measures, with HIIT providing comparable benefits to LISS in certain parameters. The results support the hypothesis that exercise intensity and complexity are positively associated with performance gains, aligning with neuroplasticity theories and the neurotrophic-stimulation hypothesis (Hillman et al., 2008). These hypotheses suggest that neuromuscular activity stimulates brain regions responsible for executive functions and neuroplastic changes, partly mediated by increased brain-derived neurotrophic factor (BDNF) levels (Zoladz & Pilc, 2010).

Figures illustrating the comparison of gain scores across groups reinforce these interpretations, highlighting the superior effects of resistance training on both physical and cognitive domains. The increased complexity of resistance exercises, which demand greater attention and neuromuscular coordination, is thought to produce more significant neurocognitive benefits (O'Leary et al., 2014). Additionally, the cerebral blood flow hypothesis offers an explanation: moderate exercise intensities upregulate cerebral perfusion and nutrient delivery, facilitating neuroplasticity and cognitive enhancement (Petersen et al., 2012). The combined influence of neurotrophic factors and increased blood flow appears to synergistically promote improvements observed in the study.

Limitations of the study include the absence of precise intensity measures during exercise sessions, relying instead on self-reported perceived exertion, which may introduce some variability. Additionally, the unequal representation of sexes poses a potential confounder, as gender differences in exercise response and neuroplasticity could influence outcomes. Future research should incorporate objective measures like heart rate monitors and include balanced gender samples to improve generalizability.

Implications of these findings are significant for educational and physical training programs, suggesting that integrating resistance training into school curricula could enhance adolescents’ brain function and academic performance. The observed benefits advocate for increased physical activity opportunities, especially those involving complex, muscular engagement, to support neurodevelopment and cognitive resilience (Singh et al., 2015).

In conclusion, the present study demonstrated that resistance exercise produces superior improvements in physical fitness and cognitive performance among adolescents. These findings underscore the importance of exercise modality and intensity in promoting neuroplasticity and suggest that school-based physical activity programs should prioritize diverse, multimodal exercises. Further investigations should explore the underlying neurobiological mechanisms more directly and examine long-term effects to optimize intervention strategies for youth development.
