Table 1 Summary of IPET concept and alterations

From: Intelligent Physical Exercise Training (IPET) in the offshore wind industry: a feasibility study with an adjusted conceptual model

  ACSM [29] IPET concept [32] IPET for WTs Justification for alterations
Concept Generic Individually tailored exercise program informed by occupational demands, musculoskeletal health, and physical performance Individually tailored exercise program informed by occupational demands, musculoskeletal health, and physical performance - N/A
Exercises Compound exercises prioritized Mix between isolation and compound exercises Compound exercises prioritized Compound exercises prioritized based on the physical demand profile (full body, heavy physical) and to allow more sets per muscle group [29]
Equipment Body weight, elastic bands, and free weights Body weight, elastic bands, and free weights Free weights prioritized Alterations based on availability of equipment and participant preferences (free weights preferred over elastic bands)
No. of set per exercise 6–15 sets per muscle group/week 2–4 sets per muscle group/week (varies) 4–10 sets per muscle group/week (varies) More sets per muscle group allowed when compound exercises are prioritized over isolation exercises
Intensity 12-8 RM (increasing over time) 15-8 RM (increasing over time) 15-5 RM (increasing over time) Trained individuals allowed to start at a higher intensity than previously untrained. RIR used to prescribe intensity instead of RM or Borg perceived exertion [35]
Frequency per week 2–3 1 (can be split between up to five shorter sessions) 1 on average (two on offshore rotation weeks, 0 on off-shift weeks) 1-hour sessions preferred by target group and management
Duration per session ~60 min 10–60 min 60 min - N/A
Time expenditure per week 2–3 h 1 h 1 h - N/A
Volume Progressive overload Steady state Progressive overload Increase in volume is considered important for continuous and optimal improvements in physical capacities with exercise over time [29, 36]
Periodization Linear periodization Varied (linear, undulating) Linear Linear periodization is simple and has shown equally effective among previously untrained individuals [35]
Outcomes General physical health and capacity Varied, e.g., musculoskeletal symptoms
- Physical capacity
- Workplace performance indicators
- Relative work intensity
- Feasibility
- Musculoskeletal symptoms
- Physical capacity
- Workplace performance indicators
