How Does Climate Affect Energy Balance in Sport
Climate directly impacts an athlete's energy expenditure and recovery by influencing body temperature regulation, hydration needs, and metabolic rates.
Extreme heat or cold forces the body to expend more energy to maintain core temperature, significantly shifting the energy balance in sport.
Impact of Heat Stress
High ambient temperatures elevate cardiovascular strain and sweat rates, significantly increasing energy expenditure for thermoregulation. "Scientists say August was Earth's hottest month they've measured" highlights the growing prevalence of such conditions. This heightened demand can deplete glycogen stores faster, impairing sustained performance.
Broader Disruption
Beyond immediate physiological effects, climate hazards disrupt training schedules and access to facilities. "Climate hazards disrupted school for 1 in 10 students in 2025: UNICEF" illustrates how climate impacts daily life and opportunities for physical activity. This global trend indirectly affects athlete development and resource allocation for sport.
