Sports Nutrology: Major Guidelines And Clinical Approaches
SPORTS NUTROLOGY & PERFORMANCE
Evidence-Based Nutrition for Peak Athletic Performance
Built as a field guide for clinicians, dietitians, and performance staff, this book links athletic outcomes to four controllable levers: fuel periodization across training and competition, protein distribution and timing, hydration and electrolytes under heat/altitude, and management of low energy availability (RED-S). Each chapter converts consensus from ACSM/AND/DC, ISSN, and the IOC into decision trees, monitoring metrics, and recovery checkpoints that fit real calendars and travel schedules.
Authored by Walter Ludwig Armin Schroff, Karyne Jorge Elias Schroff, Barbara Elisabeth Schroff, Marcos Rodrigues Pontes, and Lucas Augusto Rodrigues de Oliveira, the volume emphasizes actionable tools—sport-specific menus, checklists, and case maps—plus a pragmatic supplement-appraisal framework that integrates efficacy tiers with anti-doping safeguards and third-party certification cues.
PERFORMANCE INSIGHTS
Optimized fueling across training and competition
Performance nutrition is structured around four levers: session-specific carbohydrate availability and periodization; strategic protein distribution to drive adaptation; hydration and electrolytes for heat, altitude, and travel; and proactive screening for low energy availability (RED-S). Supplements are evaluated for efficacy and risk within anti-doping safeguards. Each element converts major consensus statements into clinic-ready actions that fit real training calendars and game demands.
Book Highlights
Training-Aligned Fuel Periodization: Structure carbohydrate availability by session and across microcycles to target adaptations and sustain competition performance, integrating energy-availability surveillance to mitigate RED-S risk. Practical pre/during/post fueling checklists align with ACSM/AND/DC guidance and the IOC’s 2023 RED-S clinical assessment framework for screening and return-to-play decisions.
Protein Timing & Distribution: Apply ISSN guidance on total daily intake alongside per-meal dosing to stimulate MPS, support recovery, and protect lean mass during heavy training or energy deficit. Protocols emphasize dose (≈0.3–0.4 g/kg), spacing (every 3–4 hours), and exercise pairing to maximize adaptations across sport contexts.
Hydration & Electrolytes in Demanding Environments: Build individualized fluid and sodium strategies via sweat-rate assessment, pre-exercise euhydration, and in-event replacement that accounts for heat, altitude, and travel. Guidance translates ACSM position stands into simple planning and monitoring tools to safeguard health and performance.
Supplement Strategy & Anti-Doping Safeguards: Use efficacy-tiered frameworks for staples like creatine and caffeine while reducing contamination risk through third-party certification and constant review of the WADA Prohibited List. Practical decision trees balance potential ergogenic value with athlete safety and eligibility.
Why is this book indispensable?
Consensus-grounded, not opinion-based
Built on authoritative positions from ACSM/AND/DC and ISSN, plus the IOC’s 2023 REDs consensus, the book aligns fueling, protein, hydration, and energy-availability practices with what leading bodies actually recommend. Readers get clear, up-to-date guardrails—especially around REDs screening and management—so policies and protocols track with current science rather than anecdote.
Actionable protocols for real calendars
Instead of abstract theory, chapters translate consensus into stepwise workflows: session-specific carbohydrate periodization, protein distribution across the day, individualized hydration/electrolyte plans for heat or altitude, and return-to-play checkpoints when low energy availability is suspected. These are mapped to practical decision trees and monitoring metrics clinicians can deploy in camps, travel, and congested competition windows.
Athlete-safe supplementation and compliance
A pragmatic supplement framework ties efficacy tiers to anti-doping safeguards, emphasizing third-party certification and continuous review of the current WADA Prohibited List. The result is a risk-managed approach that preserves eligibility while focusing on evidence-supported options like creatine and caffeine where appropriate.
Who is this book essential for?
Sports Dietitians & Clinical Nutritionists
Translate consensus on fueling, protein distribution, and hydration into day-to-day meal plans, microcycle periodization, and competition menus. The book turns joint positions into checklists and monitoring metrics you can use in consults, camps, and travel—bridging lab evidence with locker-room realities. It also helps you align documentation and education materials with widely recognized practice standards so stakeholders stay coordinated.
Team Physicians & Sports Medicine Clinicians
Use clear pathways for screening and managing low energy availability (RED-S), integrating return-to-play checkpoints with broader medical oversight. Practical algorithms connect symptom clusters, risk stratification, and follow-up testing with training modifications and nutrition interventions, so care plans are defensible and athlete-centered. Guidance is mapped to the IOC’s 2023 consensus and the RED-S Clinical Assessment Tool (CAT2).
Strength & Conditioning Coaches & Performance Directors
Convert nutrition principles into training-aligned targets: carbohydrate availability by session goal, protein timing to support adaptation, and hydration protocols for heat/altitude blocks. Workflows show how to integrate these levers with load management and recovery dashboards, helping you brief athletes and staff with numbers that matter. Protein guidance and dosing ranges are tied to established position stands to maintain consistency across the program.
Athletic Trainers, Compliance Leads & Athlete Support Personnel
Operationalize supplement decisions with a risk-managed playbook—efficacy tiers, third-party certification cues, and red-flag categories—while staying aligned with the current Prohibited List and education resources. The section supports pre-participation reviews, travel kits, and incident response when questions arise around substances or therapeutic use. It’s designed to keep athletes safer and eligible without stifling legitimate performance strategies.
