Criteria Feedback
The student communicates a relevant biological topic clearly and shows that they understand the basic relationship they want to investigate.
The student's introduction gives the reader a sensible overview of the population, measurement approach, and practical relevance of the study.
The student includes a range of relevant methodological steps such as repeated trials, rests between attempts, and participant consent.
The research focus is still broader than it needs to be because several outcomes are combined into one question.
Some parts of the rationale blur together strength, muscle mass, and metabolic risk without always separating the ideas clearly.
Several important methodological details are missing or inconsistent, especially around how the blood data were obtained and how measurement conditions were controlled.

Moderate
Criteria Feedback
The student shows a sound grasp of metabolic syndrome and related biological ideas before moving into their own data.
The student uses relevant terminology such as insulin resistance, dyslipidemia, cytokines, triglycerides, and HDL appropriately in many places.
The student connects the biological discussion to the investigation rather than leaving the source material as isolated background information.
Some biological claims are too broad or imprecise, especially where strength, muscle mass, hypertrophy, and metabolic regulation are treated as if they are the same thing.
A few clinical definitions and thresholds are inaccurate or inconsistently applied.
Several source-based claims are generalized from populations that do not fully match the student's sample, which weakens how convincingly the evidence supports their discussion.
