Article Synopsis
- A study was conducted to assess physical fitness trends among Lithuanian adolescents from 1992 to 2022, including data from nearly 18,000 individuals aged 11-17.
- Significant declines were observed in various fitness tests like the 20-m shuttle run and bent arm hang, while some improvements were noted in balance and short shuttle run performance.
- The results highlight a worrying trend of decreased health-related fitness, especially among low performers, indicating a need for national health promotion policies to address these issues.
Article Synopsis
- - The study investigates the anaerobic fitness of elite amateur boxers and how various performance metrics, like peak power and punching frequency, relate to physiological responses such as heart rate and blood lactate levels.
- - Twelve male Olympic boxers underwent several tests, including cycling and treadmill exercises, revealing that performance indices from different anaerobic tests were generally not closely linked.
- - The findings indicate a complex relationship between aerobic and anaerobic capacities in elite boxers, suggesting that improvements in one does not necessarily correlate with the other.
Carbohydrate (CHO) metabolism is crucial for short-duration, high-intensity exercise performance, but the effects of variations in glycogen availability have not been investigated in field trials of trained athletes. This study was designed to test how 1500 m time trial (TT) performance is affected by the manipulation of pre-race glycogen reserves. Competitive middle-distance runners ( = 11 (4 females)) completed a 1500 m individually paced indoor TT after abundant (high, >5 g/kg/d) or restricted (low, <1.

The tissue remodeling that happens during recovery from atrophy or injury involves changes in different cell types such as muscle fibers, and satellite and immune cells. Here, we show that the previously uncharacterized gene and protein Zfp697 is a damage-induced regulator of muscle remodeling.
